In addition to their critical roles in bone formation and remodeling, parathyroid hormone-related protein (PTHrP) and its receptor (PTHR1) are involved in progression and metastasis of many types of tumours in humans. The aims of this study were to determine the localisation and expression levels of PTHrP and PTHR1 in canine OS tissues using immunohistochemistry and to investigate if this expression is correlated with survival time. Formalin-fixed, paraffin-embedded tissue samples from 44 dogs with known survival time that had been diagnosed with primary osteosarcoma were analysed for localisation of PTHrP and PTHR1. Findings showed that both PTHrP and PTHR1 were present in all OS samples. The dogs with high level of PTHR1 protein (16%) had decreased survival time (P<0.05) compared to dogs with less PTHR1 protein. PTHrP levels did not correlate with survival time (P>0.05). The results of this study indicate that the PTHR1 is expressed differently in canine OS tissues and this may be correlated with poor prognosis. This may mean that PTHR1 may be useful as a prognostic indicator in canine OS and could represent a good therapeutic target in OS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dog" title="dog">dog</a>, <a href="https://publications.waset.org/abstracts/search?q=expression" title=" expression"> expression</a>, <a href="https://publications.waset.org/abstracts/search?q=osteosarcoma" title=" osteosarcoma"> osteosarcoma</a>, <a href="https://publications.waset.org/abstracts/search?q=parathyroid%20hormone%20receptor%201%20%28PTHR1%29" title=" parathyroid hormone receptor 1 (PTHR1)"> parathyroid hormone receptor 1 (PTHR1)</a>, <a href="https://publications.waset.org/abstracts/search?q=parathyroid%20hormone-related%20protein%20%28PTHrP%29" title=" parathyroid hormone-related protein (PTHrP)"> parathyroid hormone-related protein (PTHrP)</a>, <a href="https://publications.waset.org/abstracts/search?q=survival" title=" survival"> survival</a> </p> <a href="https://publications.waset.org/abstracts/55383/parathyroid-hormone-receptor-1-as-a-prognostic-indicator-in-canine-osteosarcoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55383.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">276</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">67</span> CSPG4 Molecular Target in Canine Melanoma, Osteosarcoma and Mammary Tumors for Novel Therapeutic Strategies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paola%20Modesto">Paola Modesto</a>, <a href="https://publications.waset.org/abstracts/search?q=Floriana%20Fruscione"> Floriana Fruscione</a>, <a href="https://publications.waset.org/abstracts/search?q=Isabella%20Martini"> Isabella Martini</a>, <a href="https://publications.waset.org/abstracts/search?q=Simona%20Perga"> Simona Perga</a>, <a href="https://publications.waset.org/abstracts/search?q=Federica%20Riccardo"> Federica Riccardo</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariateresa%20Camerino"> Mariateresa Camerino</a>, <a href="https://publications.waset.org/abstracts/search?q=Davide%20Giacobino"> Davide Giacobino</a>, <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Gola"> Cecilia Gola</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Licenziato"> Luca Licenziato</a>, <a href="https://publications.waset.org/abstracts/search?q=Elisabetta%20Razzuoli"> Elisabetta Razzuoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Katia%20Varello"> Katia Varello</a>, <a href="https://publications.waset.org/abstracts/search?q=Lorella%20Maniscalco"> Lorella Maniscalco</a>, <a href="https://publications.waset.org/abstracts/search?q=Elena%20Bozzetta"> Elena Bozzetta</a>, <a href="https://publications.waset.org/abstracts/search?q=Angelo%20Ferrari"> Angelo Ferrari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Canine and human melanoma, osteosarcoma (OSA), and mammary carcinomas are aggressive tumors with common characteristics making dogs a good model for comparative oncology. Novel therapeutic strategies against these tumors could be useful to both species. In humans, chondroitin sulphate proteoglycan 4 (CSPG4) is a marker involved in tumor progression and could be a candidate target for immunotherapy. The anti-CSPG4 DNA electrovaccination has shown to be an effective approach for canine malignant melanoma (CMM) [1]. An immunohistochemistry evaluation of CSPG4 expression in tumour tissue is generally performed prior to electrovaccination. To assess the possibility to perform a rapid molecular evaluation and in order to validate these spontaneous canine tumors as the model for human studies, we investigate the CSPG4 gene expression by RT qPCR in CMM, OSA, and canine mammary tumors (CMT). The total RNA was extracted from RNAlater stored tissue samples (CMM n=16; OSA n=13; CMT n=6; five paired normal tissues for CMM, five paired normal tissues for OSA and one paired normal tissue for CMT), retro-transcribed and then analyzed by duplex RT-qPCR using two different TaqMan assays for the target gene CSPG4 and the internal reference gene (RG) Ribosomal Protein S19 (RPS19). RPS19 was selected from a panel of 9 candidate RGs, according to NormFinder analysis following the protocol already described [2]. Relative expression was analyzed by CFX Maestro™ Software. Student t-test and ANOVA were performed (significance set at P<0.05). Results showed that gene expression of CSPG4 in OSA tissues is significantly increased by 3-4 folds when compared to controls. In CMT, gene expression of the target was increased from 1.5 to 19.9 folds. In melanoma, although an increasing trend was observed, no significant differences between the two groups were highlighted. Immunohistochemistry analysis of the two cancer types showed that the expression of CSPG4 within CMM is concentrated in isles of cells compared to OSA, where the distribution of positive cells is homogeneous. This evidence could explain the differences in gene expression results.CSPG4 immunohistochemistry evaluation in mammary carcinoma is in progress. The evidence of CSPG4 expression in a different type of canine tumors opens the way to the possibility of extending the CSPG4 immunotherapy marker in CMM, OSA, and CMT and may have an impact to translate this strategy modality to human oncology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=canine%20melanoma" title="canine melanoma">canine melanoma</a>, <a href="https://publications.waset.org/abstracts/search?q=canine%20mammary%20carcinomas" title=" canine mammary carcinomas"> canine mammary carcinomas</a>, <a href="https://publications.waset.org/abstracts/search?q=canine%20osteosarcoma" title=" canine osteosarcoma"> canine osteosarcoma</a>, <a href="https://publications.waset.org/abstracts/search?q=CSPG4" title=" CSPG4"> CSPG4</a>, <a href="https://publications.waset.org/abstracts/search?q=gene%20expression" title=" gene expression"> gene expression</a>, <a href="https://publications.waset.org/abstracts/search?q=immunotherapy" title=" immunotherapy"> immunotherapy</a> </p> <a href="https://publications.waset.org/abstracts/141925/cspg4-molecular-target-in-canine-melanoma-osteosarcoma-and-mammary-tumors-for-novel-therapeutic-strategies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141925.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">174</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">66</span> Hydrogen, a Novel Therapeutic Molecule, in Osteosarcoma Disease</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Priyanka%20Sharma">Priyanka Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajeshwar%20Nath%20Srivastava"> Rajeshwar Nath Srivastava</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hydrogen has a high level of efficacy in suppressing tumour growth. The role of hydrogen in cancer treatment is unclear. This groundbreaking research will focus on the most effective therapeutic approach for osteosarcoma. Recent data reveals that hydrogen, a naturally occurring gaseous chemical, can protect cells from death. However, little is known about the signalling pathways that regulate cardiac cell death and individual apoptosis signalling by H2 and its downstream targets. According to certain research, the anti-tumor effect of H2 released by magnesium-based biomaterials is mediated by the P53-mediated lysosome-mitochondria apoptosis signalling pathway, bolstering the biomaterial's therapeutic potential as a localised anti-tumor treatment. The role of the H2 molecule in the signalling of apoptotic, autophagic, necroptotic, and pyroptotic cell death in Osteosarcoma is discussed in this paper. Potential Hydrogen-based therapy techniques will broaden the treatment horizon for Osteosarcoma. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=osteosarcoma" title="osteosarcoma">osteosarcoma</a>, <a href="https://publications.waset.org/abstracts/search?q=metastasis" title=" metastasis"> metastasis</a>, <a href="https://publications.waset.org/abstracts/search?q=hhydrogen" title=" hhydrogen"> hhydrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=therapeutic" title=" therapeutic"> therapeutic</a> </p> <a href="https://publications.waset.org/abstracts/146908/hydrogen-a-novel-therapeutic-molecule-in-osteosarcoma-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146908.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">139</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">65</span> Comparison of Transforming Growth Factor-β1 Levels in the Human Gingival Sulcus during Canine Retraction Using Elastic Chain and Closed Coil Spring </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sri%20Suparwitri">Sri Suparwitri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> When an orthodontic force is applied to a tooth, an inflammatory response is initiated then lead to bone remodeling process, and the process accommodates tooth movement. One of cytokine that plays a prominent role in bone remodeling process was transforming growth factor-beta 1 (TGF-β1). The purpose of this study was to identify and compare changes of TGF-β1 in human gingival crevicular fluid during canine retraction using elastic chain and closed coil spring. Ten patients (mean age 20.7 ± 2.9 years) participated. The patients were entering the space closure phase of fixed orthodontic treatment. An upper canine of each patient was retracted using elastic chain, and the contralateral canine was retracted using closed coil spring. Gingival crevicular fluid samples were collected from the canine teeth before and 7 days after the force was applied. Transforming growth factor-beta 1 was determined by enzyme-linked immunosorbent assay (ELISA). The concentrations of TGF-β1 at 7 days were significantly higher compared to before canine retraction in both groups. In the evaluation of between-group difference, before retraction, the difference was insignificant, whereas at 7 days significantly higher values were determined in the closed coil spring group compared to elastic chain group. The result suggests that TGF-β1 is associated with the bone remodeling that occurs during canine distalization movement. Closed coil spring gave higher TGF-β1 concentrations thus more bone remodeling occurred and may be considered the treatment of choice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=closed%20coil%20spring" title="closed coil spring">closed coil spring</a>, <a href="https://publications.waset.org/abstracts/search?q=elastic%20chain" title=" elastic chain"> elastic chain</a>, <a href="https://publications.waset.org/abstracts/search?q=gingival%20crevicular%20fluid" title=" gingival crevicular fluid"> gingival crevicular fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=TGF-%CE%B21" title=" TGF-β1"> TGF-β1</a> </p> <a href="https://publications.waset.org/abstracts/75727/comparison-of-transforming-growth-factor-v1-levels-in-the-human-gingival-sulcus-during-canine-retraction-using-elastic-chain-and-closed-coil-spring" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75727.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">170</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">64</span> Impacted Maxillary Canines and Associated Dental Anomalies </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Athanasia%20Eirini%20Zarkadi">Athanasia Eirini Zarkadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Despoina%20Balli"> Despoina Balli</a>, <a href="https://publications.waset.org/abstracts/search?q=Olga%20Elpis%20Kolokitha"> Olga Elpis Kolokitha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: Impacted maxillary canines are a frequent condition and a common reason for patients seeking orthodontic treatment. Their simultaneous presence with dental anomalies raises a question about their possible connection. The aim of this study was to investigate the association of maxillary impacted canines with dental anomalies. Materials and Methods: Files of 874 patients from an orthodontic private practice in Greece were evaluated for the presence of maxillary impacted canines. From this sample, a group of 97 patients (39 males and 58 females) with at least one impacted maxillary canine were selected and consisted of the study group (canine impaction group) of this study. This group was compared to a control group of 97 patients (42 males and 55 females) that was created by random selection from the initial sample without maxillary canine impaction. The impaction diagnosis was made from the panoramic radiographs and confirmed from the surgery. The association between maxillary canine impaction and dental anomalies was examined with the chi-square test. A classification tree was created to further investigate the relations between impaction and dental anomalies. The reproducibility of diagnoses was assessed by re-examining the records of 25 patients two weeks after the first examination. Results: The found associated anomalies were cone-shaped upper lateral incisors and infraocclusion of deciduous molars. There is a significant increase in the prevalence of 12,4% of distal displacement of the unerupted mandibular second premolar in the canine impaction group compared to the control group that was 7,2%. The classification tree showed that the presence of a cone-shaped maxillary lateral incisor gave rise to the probability of an impacted canine to 83,3%. Conclusions: The presence of cone-shaped maxillary lateral incisors and infraocclusion of deciduous molars can be considered valuable early risk indicators for maxillary canine impaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cone-shaped%20maxillary%20lateral%20incisors" title="cone-shaped maxillary lateral incisors">cone-shaped maxillary lateral incisors</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20anomalies" title=" dental anomalies"> dental anomalies</a>, <a href="https://publications.waset.org/abstracts/search?q=impacted%20canines" title=" impacted canines"> impacted canines</a>, <a href="https://publications.waset.org/abstracts/search?q=infraoccluded%20deciduous%20molars" title=" infraoccluded deciduous molars "> infraoccluded deciduous molars </a> </p> <a href="https://publications.waset.org/abstracts/133892/impacted-maxillary-canines-and-associated-dental-anomalies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133892.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">148</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">63</span> Palliative Orthovoltage Radiotherapy and Subcutaneous Infusion of Carboplatin for Treatment of Appendicular Osteosarcoma in Dogs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kathryn%20L.%20Duncan">Kathryn L.

This can preclude the use of palliative radiation therapy for the treatment of appendicular osteosarcoma in dogs. The objective of this study was to retrospectively assess the adverse effects and survival times of dogs with appendicular osteosarcoma that were treated with hypofractionated orthovoltage radiation therapy and adjunctive carboplatin chemotherapy administered via a single subcutaneous infusion. Medical records were reviewed retrospectively to identify client-owned dogs with spontaneously occurring appendicular osteosarcoma that was treated with palliative orthovoltage radiation therapy and a single subcutaneous infusion of carboplatin. Data recorded included signalment, tumour location, results of diagnostic imaging, haematologic and serum biochemical analyses, adverse effects of radiation therapy and chemotherapy, and survival times. Kaplan-Meier survival analysis was performed, and log-rank analysis was used to determine the impact of specific patient variables on survival time. Twenty-three dogs were identified that met the inclusion criteria. Median survival time for dogs was 182 days. Eleven dogs had adverse haematologic effects, 3 had adverse gastrointestinal effects, 6 had adverse effects at the radiation site and 7 developed infections at the carboplatin infusion site. No statistically significant differences were identified in survival times based on sex, tumour location, development of infection, or pretreatment serum alkaline phosphatase. Median survival time and incidence of adverse effects were comparable to those previously reported in dogs undergoing palliative radiation therapy with megavoltage or cobalt radiation sources and conventional intravenous carboplatin chemotherapy. The use of orthovoltage palliative radiation therapy may be a reasonable alternative to megavoltage radiation in locations where access is limited. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=radiotherapy" title="radiotherapy">radiotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=veterinary%20oncology" title=" veterinary oncology"> veterinary oncology</a>, <a href="https://publications.waset.org/abstracts/search?q=chemotherapy" title=" chemotherapy"> chemotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=osteosarcoma" title=" osteosarcoma"> osteosarcoma</a> </p> <a href="https://publications.waset.org/abstracts/147082/palliative-orthovoltage-radiotherapy-and-subcutaneous-infusion-of-carboplatin-for-treatment-of-appendicular-osteosarcoma-in-dogs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147082.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">73</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">62</span> Production of Recombinant VP2 Protein of Canine Parvovirus 2a Using Baculovirus Expression System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soo%20Dong%20Cho">Soo Dong Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=In-Ohk%20Ouh"> In-Ohk Ouh</a>, <a href="https://publications.waset.org/abstracts/search?q=Byeong%20Sul%20Kang"> Byeong Sul Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyeon%20Park"> Seyeon Park</a>, <a href="https://publications.waset.org/abstracts/search?q=In-Soo%20Cho"> In-Soo Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae%20Young%20Song"> Jae Young Song</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An VP2 gene from the current prevalent CPV (Canine Parvovirus) strain (new CPV-2a) in the Republic of Korea was expressed in a baculovirus expression system.

Propagation of recombinant baculoviruses and expression of the VP2 protein were performed in the Sf9 cell line maintained. The proteins were detected to Western blot anlaysis. CPV-2a VP2 was detected by Western blotting the monoclonal antibodies recognized 6x His and the band had a molecular weight of 65 KDa. We demonstrated that recombinant CPV-2a VP2 expression in baculovirus. The recombinant CPV-2a VP2 may able to development of specific diagnostic test and vaccination of against CPV2. This study provides a foundation for application of CPV2 on the development of new CPV2 subunit vaccine. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=baculovirus" title="baculovirus">baculovirus</a>, <a href="https://publications.waset.org/abstracts/search?q=canine%20parvovirus%202a" title=" canine parvovirus 2a"> canine parvovirus 2a</a>, <a href="https://publications.waset.org/abstracts/search?q=Dog" title=" Dog"> Dog</a>, <a href="https://publications.waset.org/abstracts/search?q=Korea" title=" Korea"> Korea</a> </p> <a href="https://publications.waset.org/abstracts/93351/production-of-recombinant-vp2-protein-of-canine-parvovirus-2a-using-baculovirus-expression-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93351.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">244</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">61</span> Apoptosis Inducing Potential of Onosma Bracteata Wall. in Mg-63 Human Osteosarcoma Cells via cdk2/Cyclin E Pathway</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ajay%20Kumar">Ajay Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Satwinderjeet%20Kaur"> Satwinderjeet Kaur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Onosma bracteata Wall. (Boraginaceae), is known to be a medicinal plant, useful in the treatment of body swellings, abdominal pain and urinary calculi, etc. The present study focused on the radical scavenging and cancer growth inhibitory properties of isolates from O. bracteata. Obea fraction demonstrated noticeable free radical scavenging ability along with antiproliferative activity in human osteosarcoma MG-63, human neuroblastoma IMR-32, and human lung cancer A549 cell lines using MTT assay with GI50 values of 88.56, 101.61 and 112.7 μg/ml, respectively. The scanning electron and confocal microscopy studies showed morphological alterations including nuclear condensation and formation of apoptotic bodies in osteosarcoma MG-63 cells. Obea fraction in osteosarcoma MG-63 cells augmented the reactive oxygen species (ROS) level and decreased the mitochondrial membrane potential. Flow cytometry analysis revealed the Obea treated cells to be arrested in the G0/G1 phase in a dose dependent manner supported by the observed increase in the early apoptotic cell population. Western blotting analysis showed that the expression of p-NF-kB, COX-2, p-Akt, and Bcl-xL decreased whereas, the expression of GSK-3β, p53, caspase-3 and caspase-9 proteins increased. The downregulation of Bcl-2, Cyclin E, CDK2 and mortalin gene expression and upregulation of p53 genes was unfolded in RT-qPCR studies. The presence of catechin, kaempferol, Onosmin A and epicatechin, as revealed in high-performance liquid chromatography (HPLC) studies, contributes towards the chemopreventive potential of O. bracteata which can be tapped for chemotherapeutic use. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=apoptosis" title="apoptosis">apoptosis</a>, <a href="https://publications.waset.org/abstracts/search?q=confocal%20microscopy" title=" confocal microscopy"> confocal microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=HPLC" title=" HPLC"> HPLC</a>, <a href="https://publications.waset.org/abstracts/search?q=mitochondria%20membrane%20potential" title=" mitochondria membrane potential"> mitochondria membrane potential</a>, <a href="https://publications.waset.org/abstracts/search?q=reactive%20oxygen%20species" title=" reactive oxygen species"> reactive oxygen species</a> </p> <a href="https://publications.waset.org/abstracts/136286/apoptosis-inducing-potential-of-onosma-bracteata-wall-in-mg-63-human-osteosarcoma-cells-via-cdk2cyclin-e-pathway" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136286.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">136</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">60</span> From Dog to Dog: Potential Probiotic and Immunomodulatory Strains Isolated from Canine Milk</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paula%20Buldres">Paula Buldres</a>, <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Toledo"> Jorge Toledo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objectives: This study aimed to characterize potential probiotic strains isolated from canine breast milk for use in dogs with enteropathies. Methodology: Six canine breast milk strains, one canine colostrum strain, and one control porcine breast milk strain were characterized. According to its functional properties of resistance to acids, different concentrations of bile salts, and pancreatin, its presumptive properties of safety and inhibitory effect on pathogens, non-cytotoxic characteristics, and adhesion to the intestine. The immunomodulatory effect of formulations with better probiotic characterization in vitro and in vivo was also analyzed. Results: Two strains characterized as potential probiotics were obtained, which corresponded to the canine strains (TUCO-16 and TUCO-17), presenting resistance to acidic pH, bile salts, and pancreatin, as well as an inhibitory effect on pathogenic Escherichia coli, Salmonella sp., and Clostridium perfringens. Strains TUCO-16 and TUCO-17 induced a significant increase in the expression of TNF-α and IL-8 in canine macrophages, respectively. Expression analyses of pattern recognition receptors in DH82 cells suggest that TUCO-16 and TUCO-17 might increase the TLR2 expression marker, and porcine strain (TUCO-4) increases the NOD2 expression marker. Based on the count obtained and the encapsulation yield, the best formulations correspond to FOS-Inulin for the TUCO-17 and TUCO-4 strains; Maltodextrin-Inulin for TUCO-16. All the strains are non-cytotoxic. The strain that showed the highest adhesion to intestinal epithelial cells was TUCO-17 with the FOS-Inulin formulation. On the other hand, the probiotics decreased the expression of pro-inflammatory markers in vivo, both in the intestine and in the spleen of mice. Conclusion: The combination of these three strains under study (TUCO-16, TUCO-17, and TUCO-4) would cover the probiotic properties in formulation and immunomodulation of all the markers under study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=probiotics" title="probiotics">probiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=gastrointestinal%20infec" title=" gastrointestinal infec"> gastrointestinal infec</a>, <a href="https://publications.waset.org/abstracts/search?q=dog" title=" dog"> dog</a>, <a href="https://publications.waset.org/abstracts/search?q=probiotic%20formulation" title=" probiotic formulation"> probiotic formulation</a>, <a href="https://publications.waset.org/abstracts/search?q=immunomodulatory%20probiotics" title=" immunomodulatory probiotics"> immunomodulatory probiotics</a> </p> <a href="https://publications.waset.org/abstracts/163977/from-dog-to-dog-potential-probiotic-and-immunomodulatory-strains-isolated-from-canine-milk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163977.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">68</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59</span> Trial of Faecal Microbial Transplantation for the Prevention of Canine Atopic Dermatitis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Caroline%20F.%20Moeser">Caroline F.

Low diversity within the gut can predispose to the development of allergic skin conditions, and a greater diversity of the gastrointestinal microflora has been associated with a reduction of skin flares in people with atopic dermatitis. Manipulation of the gut microflora has been used as a treatment option for several conditions in people, but there is limited data available on the use of faecal transplantation as a preventative measure in either people or dogs. Six, 4-month-old pups from a litter of ten were presented for diarrhea and/or signs of skin disease (chronic scratching, otitis externa). Of these pups, two were given probiotics with a resultant resolution of diarrhea. The other four pups were given faecal transplantation, either as a sole treatment or in combination with other treatments. Follow-up on the litter of ten pups was performed at 18 months of age. At this stage, the four pups that had received faecal transplantation had resolved all clinical signs and had no recurrence of either skin or gastrointestinal symptoms. Of the remaining six pups from the litter, all had developed at least one episode of Malassezia otitis externa within the period of 5 months to 18 months of age. Two pups had developed two Malassezia otitis infections, and one had developed three Malassezia otitis infections during this period. Favrot’s criteria for the diagnosis of canine atopic dermatitis include chronic or recurrent Malassezia infections by the age of three years. Early results from this litter predict a reduction in the development of canine atopic disease in dogs given faecal microbial transplantation. Follow-up studies at three years of age and within a larger population of dogs can enhance understanding of the impact of early faecal transplantation in the prevention of canine atopic dermatitis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=canine%20atopic%20dermatitis" title="canine atopic dermatitis">canine atopic dermatitis</a>, <a href="https://publications.waset.org/abstracts/search?q=faecal%20microbial%20transplant" title=" faecal microbial transplant"> faecal microbial transplant</a>, <a href="https://publications.waset.org/abstracts/search?q=skin-gut%20axis" title=" skin-gut axis"> skin-gut axis</a>, <a href="https://publications.waset.org/abstracts/search?q=otitis" title=" otitis"> otitis</a> </p> <a href="https://publications.waset.org/abstracts/133176/trial-of-faecal-microbial-transplantation-for-the-prevention-of-canine-atopic-dermatitis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133176.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">158</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">58</span> Antibacterial Effects of Garcinia mangostana on Canine Superficial Pyoderma Pathogen, Staphylococcus pseudintermedius</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sineenat%20Kempubpha">Sineenat Kempubpha</a>, <a href="https://publications.waset.org/abstracts/search?q=Phornpa-Ngan%20Muadmuang"> Phornpa-Ngan Muadmuang</a>, <a href="https://publications.waset.org/abstracts/search?q=Putthamas%20%20Phetmuangprab"> Putthamas Phetmuangprab</a>, <a href="https://publications.waset.org/abstracts/search?q=Surin%20Promphet"> Surin Promphet</a>, <a href="https://publications.waset.org/abstracts/search?q=Sopita%20Bandit"> Sopita Bandit</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Discarded pericarp of mangosteen (Garcinia mangostana) is a benefit to be developed as veterinary phytopharmacal products since it made up of abundance pharmacological active compounds. The active compounds of mangosteen pericarp not only act as an antihistamine, an anti-inflammatory, heart disease and HIV therapeutic substances but also act as antibacterial and antifungal agents. Aim: This study was an in vitro procedural attempt to determine the antibacterial effects of mangosteen pericarp 95% ethanol extract on the main causative pathogen of canine superficial pyoderma, Staphylococcus pseudintermedius. Methods: S. pseudintermedius were collected from various sites of the skin of canine superficial pyoderma dogs and were revived and lawn cultured. The S. pseudintermedius growth inhibition study was determined by disc diffusion technique, the mangosteen pericarp crude extracted was dissolved in 3 types of solvents (95% ethanol, 2% DMSO and distilled water, respectively). The micro broth dilution technique was used for determining both minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values. Statistical analysis was done by calculating the mean of the zones of inhibition of tested microorganisms. Results: S. pseudintermedius growth inhibition study showed that the inhibition efficacy of 95% ethanol was greater than the inhibition efficacy of 2% DMSO and distilled water (9.10±0.18 mm, 6.95±0.60 mm and 6.80±0.18 mm, respectively). The MIC value was 125 µg/ml and the MBC value was 1 mg/ml. Conclusion: Mangosteen pericarp extract dissolved with 95% ethanol showed the highest zone of inhibition against the tested microorganisms. The MIC value was 125 µg/ml and the MBC value was 1 mg/ml which suggests its potent antibacterial action against S. pseudintermedius. However, further analytical studies are needed to isolate the key molecules of mangosteen pericarp for higher effect on canine superficial pyoderma microorganism therapeutic products. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mangosteen" title="mangosteen">mangosteen</a>, <a href="https://publications.waset.org/abstracts/search?q=Garcinia%20mangostana" title=" Garcinia mangostana"> Garcinia mangostana</a>, <a href="https://publications.waset.org/abstracts/search?q=Staphylococcus%20pseudintermedius" title=" Staphylococcus pseudintermedius"> Staphylococcus pseudintermedius</a>, <a href="https://publications.waset.org/abstracts/search?q=canine%20superficial%20pyoderma" title=" canine superficial pyoderma"> canine superficial pyoderma</a>, <a href="https://publications.waset.org/abstracts/search?q=in%20vitro%20study" title=" in vitro study"> in vitro study</a> </p> <a href="https://publications.waset.org/abstracts/92382/antibacterial-effects-of-garcinia-mangostana-on-canine-superficial-pyoderma-pathogen-staphylococcus-pseudintermedius" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92382.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">280</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">57</span> Identification and Characterization of 18S rRNA Gene of Demodex Canis From the Dog Population of Mizoram, India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Moneesh%20Thakur">Moneesh Thakur</a>, <a href="https://publications.waset.org/abstracts/search?q=Hridayesh%20Prasad"> Hridayesh Prasad</a>, <a href="https://publications.waset.org/abstracts/search?q=Nikitasha%20Bora"> Nikitasha Bora</a>, <a href="https://publications.waset.org/abstracts/search?q=Parimal%20Roy%20Choudhary"> Parimal Roy Choudhary</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20K.%20Samanta"> A.

Demodicosis in dogs is due the prominent growth of Demodex. Out of various canine Demodex spp., Demodex canis is the most often involved species. Canine demodicosis can occur as either a localized or generalized form of demodicosis severely affect the dogs and in non-treated dogs may cause death. This study was planned with the aim to screen and characterize the 18S rRNA gene of isolated Demodex canis. A total of 1200 dogs were screened during this study period. The skin scrapings of all the suspected dogs were examined under a microscope at 100X magnification for the presence of Demodex canis. The skin scrapings positive for Demodex canis were examined using PCR for confirmation. A total of 35 dogs were confirmed a positive result for D. canis based on 18S rRNA gene amplification by PCR. Further, the 18S rRNA gene of isolated Demodex canis was cloned and sequenced for genome analysis. On the sequence analysis, it was found that isolated sequence (GenBank Accession No. MK177513) had close similarity (99.7%) to that of D. canis genotype of China (Accession No. MG372254). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PCR" title="PCR">PCR</a>, <a href="https://publications.waset.org/abstracts/search?q=phylogenetic%20analysis" title=" phylogenetic analysis"> phylogenetic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=cloning%20and%20sequening" title=" cloning and sequening"> cloning and sequening</a>, <a href="https://publications.waset.org/abstracts/search?q=Demodex%20canis" title=" Demodex canis"> Demodex canis</a> </p> <a href="https://publications.waset.org/abstracts/172036/identification-and-characterization-of-18s-rrna-gene-of-demodex-canis-from-the-dog-population-of-mizoram-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172036.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">93</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">56</span> Research on the Role of Platelet Derived Growth Factor Receptor Beta in Promoting Dedifferentiation and Pulmonary Metastasis of Osteosarcoma Under Hypoxic Microenvironment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enjie%20Xu">Enjie Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhen%20Huang"> Zhen Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Kunpeng%20Zhu"> Kunpeng Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jianping%20Hu"> Jianping Hu</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaolong%20Ma"> Xiaolong Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Yongjie%20Wang"> Yongjie Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiazhuang%20Zhu"> Jiazhuang Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Chunlin%20Zhang"> Chunlin Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Abstract: Hypoxia and dedifferentiation of osteosarcoma (OS) cells leads to poor prognosis. We plan to identify the role of hypoxia on dedifferentiation and the associated signaling pathways. We performed a sphere formation assay and determined spheroid cells as dedifferentiated cells by detecting stem cell-like markers. RNAi assay was used to explore the expression relationship between hypoxia inducible factor 1 subunit alpha (HIF1A) and platelet derived growth factor receptor beta (PDGFRB). We obtained PDGFRB knockdown and overexpression cells through lentiviral infection experiments and the effects of PDGFRB on cytoskeleton rearrangement and cell adhesion were explored by immunocytochemistry. Wound-healing experiments, transwell assays, and animal trials were employed to investigate the effect of PDGFRB on OS metastasis. Dedifferentiated OS cells were found to exhibit high expression of HIF1A and PDGFRB, and HIF1A promoted the expression of PDGFRB, subsequently activated ras homolog family member A (RhoA), and increased the phosphorylation of myosin light chain (MLC). PDGFRB also enhanced the phosphorylation of focal adhesion kinase (FAK). The OS cell morphology and vinculin distribution were altered by PDGFRB. PDGFRB also promoted cell dedifferentiation and had a significant impact on the metastasis of OS cells both in vitro and in vivo. Our results demonstrated that HIF1A up-regulated PDGFRB under hypoxic conditions, and PDGFRB regulated the actin cytoskeleton by activating RhoA and subsequently phosphorylating MLC, thereby promoting OS dedifferentiation and pulmonary metastasis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=osteosarcoma" title="osteosarcoma">osteosarcoma</a>, <a href="https://publications.waset.org/abstracts/search?q=dedifferentiation" title=" dedifferentiation"> dedifferentiation</a>, <a href="https://publications.waset.org/abstracts/search?q=metastasis" title=" metastasis"> metastasis</a>, <a href="https://publications.waset.org/abstracts/search?q=cytoskeleton%20rearrangement" title=" cytoskeleton rearrangement"> cytoskeleton rearrangement</a>, <a href="https://publications.waset.org/abstracts/search?q=PDGFRB" title=" PDGFRB"> PDGFRB</a>, <a href="https://publications.waset.org/abstracts/search?q=hypoxia" title=" hypoxia"> hypoxia</a> </p> <a href="https://publications.waset.org/abstracts/184648/research-on-the-role-of-platelet-derived-growth-factor-receptor-beta-in-promoting-dedifferentiation-and-pulmonary-metastasis-of-osteosarcoma-under-hypoxic-microenvironment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184648.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">47</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">55</span> Targeting the EphA2 Receptor Tyrosine Kinases in Melanoma Cancer, both in Humans and Dogs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shabnam%20Abdi">Shabnam Abdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Behzad%20Toosi"> Behzad Toosi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Melanoma is the most lethal type of malignant skin cancer in humans and dogs since it spreads rapidly throughout the body. Despite significant advances in treatment, cancer at an advanced stage has a poor prognosis. Hence, more effective treatments are needed to enhance outcomes with fewer side effects. Erythropoietin-producing hepatocellular receptors are the largest family of receptor tyrosine kinases and are divided into two subfamilies, EphA and EphB, both of which play a significant role in disease, especially cancer. Due to their association with proliferation and invasion in many aggressive types of cancer, Eph receptor tyrosine kinases (Eph RTKs) are promising cancer therapy molecules. Because these receptors have not been studied in canine melanoma, we investigated how EphA2 influences survival and tumorigenicity of melanoma cells. Methods: Expression of EphA2 protein in canine melanoma cell lines and human melanoma cell line was evaluated by Western blot. Melanoma cells were transduced with lentiviral particles encoding Eph-targeting shRNAs or non-silencing shRNAs (control) for silencing the expression of EphA2 receptor, and silencing was confirmed by Western blotting and immunofluorescence. The effect of siRNA treatment on cellular proliferation, colony formation, tumorsphere assay, invasion was analyzed by Resazurin assay Matrigel invasion assay, respectively. Results: Expression of EphA2 was detected in canine and human melanoma cell lines. Moreover, stably silencing EphA2 by specific shRNAs significantly and consistently decreased the expression of EphA2 protein in both human and canine melanoma cells. Proliferation, colony formation, tumorsphere and invasion of melanoma cells were significantly decreased in EphA2 siRNA-treated cells compared to control. Conclusion: Our data provide the first functional evidence that the EphA2 receptor plays a critical role in the malignant cellular behavior of melanoma in both human and dogs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ephA2" title="ephA2">ephA2</a>, <a href="https://publications.waset.org/abstracts/search?q=targeting" title=" targeting"> targeting</a>, <a href="https://publications.waset.org/abstracts/search?q=melanoma" title=" melanoma"> melanoma</a>, <a href="https://publications.waset.org/abstracts/search?q=human" title=" human"> human</a>, <a href="https://publications.waset.org/abstracts/search?q=canine" title=" canine"> canine</a> </p> <a href="https://publications.waset.org/abstracts/173830/targeting-the-epha2-receptor-tyrosine-kinases-in-melanoma-cancer-both-in-humans-and-dogs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173830.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">60</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">54</span> A Study on Reliability of Gender and Stature Determination by Odontometric and Craniofacial Anthropometric Parameters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Churamani%20Pokhrel">Churamani Pokhrel</a>, <a href="https://publications.waset.org/abstracts/search?q=C.%20B.%20Jha"> C.

The determination of adult sex and stature are two of the four key factors (sex, stature, age, and race) in identification of an individual. Craniofacial and odontometric parameters are important tools for forensic anthropologists when it is not possible to apply advanced techniques for identification purposes. The present study provides anthropometric correlation of the parameters with stature and gender and also devises regression formulae for reconstruction of stature. A total of 312 Nepalese students with equal distribution of sex i.e., 156 male and 156 female students of age 18-35 years were taken for the study. Total of 10 parameters were measured (age, sex, stature, head circumference, head length, head breadth, facial height, bi-zygomatic width, mesio-distal canine width and inter-canine distance of both maxilla and mandible). Co-relation and regression analysis was done to find the association between the parameters. All parameters were found to be greater in males than females and each was found to be statistically significant. Out of total 312 samples, the best regressor for the determination of stature was head circumference and mandibular inter-canine width and that for gender was head circumference and right mandibular teeth. The accuracy of prediction was 83%. Regression equations and analysis generated from craniofacial and odontometric parameters can be a supplementary approach for the estimation of stature and gender when extremities are not available. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=craniofacial" title="craniofacial">craniofacial</a>, <a href="https://publications.waset.org/abstracts/search?q=gender" title=" gender"> gender</a>, <a href="https://publications.waset.org/abstracts/search?q=odontometric" title=" odontometric"> odontometric</a>, <a href="https://publications.waset.org/abstracts/search?q=stature" title=" stature"> stature</a> </p> <a href="https://publications.waset.org/abstracts/83118/a-study-on-reliability-of-gender-and-stature-determination-by-odontometric-and-craniofacial-anthropometric-parameters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83118.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">191</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">53</span> Fluoride-Induced Stress and Its Association with Bone Developmental Pathway in Osteosarcoma Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Deepa%20Gandhi">Deepa Gandhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Pravin%20K.%20Naoghare"> Pravin K.

Present study reports oxidative/inflammatory signatures in fluoride exposed human osteosarcoma (HOS) cells and its possible association with the genes involved in bone developmental pathway. Microarray analysis was performed to understand the possible molecular mechanisms of stress-mediated bone lose in HOS cells. Cells were chronically exposed with sub-lethal concentration of fluoride. Global gene expression is profiling revealed 34 up regulated and 2598 down-regulated genes, which were associated with several biological processes including bone development, osteoblast differentiation, stress response, inflammatory response, apoptosis, regulation of cell proliferation. Microarray data were further validated through qRT-PCR and western blot analyses using key representative genes. Based on these findings, it can be proposed that chronic exposure of fluoride may impair bone development via oxidative and inflammatory stress. The present finding also provides important biological clues, which will be helpful for the development of therapeutic targets against diseases related bone. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bone" title="bone">bone</a>, <a href="https://publications.waset.org/abstracts/search?q=HOS%20cells" title=" HOS cells"> HOS cells</a>, <a href="https://publications.waset.org/abstracts/search?q=microarray" title=" microarray"> microarray</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a> </p> <a href="https://publications.waset.org/abstracts/40877/fluoride-induced-stress-and-its-association-with-bone-developmental-pathway-in-osteosarcoma-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40877.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">377</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">52</span> In vitro Modulation of Cytokine Expression by an Aqueous Licorice Extract in Canine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Watson">A.

Such activities could have value for the management of common immunological diseases in dogs, such as environmental allergy. This study investigated the potential of a Licorice root extract (LRE) to influence the relative expression of Th-1, Th-2, and Th-17 cytokines in canine peripheral blood mononuclear cells (PBMC). Methods: A LRE was prepared using an alcoholic-aqueous-based solvent method. The extract was tested in three in vitro assays using canine leukocytes to determine its toxicity and immunoregulatory profile. Extract toxicity was assessed using the human T-lymphocyte cell line, Jurkat E6.1. The impact of the extract on the proliferation of concanavalin-activated canine PBMC was also determined. Finally, the extract was assessed for its ability to influence cytokine release in activated PBMC, measuring culture medium concentrations of interleukin-17, interferon gamma, and interleukin-4. One-way ANOVA followed by Dunnett’s post-test was used for statistics using concanavalin positive control as reference (p ≤ 0.05). Results: There was evidence that the LRE had specific immunomodulatory properties, causing significant inhibition of IL4 expression over a non-toxic/non-cytostatic concentration range (p < 0.001). In the same cell incubations, there was no significant impact on IL17 nor IFNg over the same non-toxic/non-cytostatic concentration range. Conclusion: The study provides in vitro evidence that LRE preferentially reduces the expression of a Th-2-type cytokine, IL4. The dog population, as with humans, is prone to conditions associated with a Th-2 bias of the immune system, such as environmental allergy. Based on these results, licorice merits further evaluation as a useful immune modulator for such allergic diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cytokine" title="cytokine">cytokine</a>, <a href="https://publications.waset.org/abstracts/search?q=Glycyrrhiza%20glabra" title=" Glycyrrhiza glabra"> Glycyrrhiza glabra</a>, <a href="https://publications.waset.org/abstracts/search?q=peripheral%20blood%20mononuclear%20cells" title=" peripheral blood mononuclear cells"> peripheral blood mononuclear cells</a>, <a href="https://publications.waset.org/abstracts/search?q=T-cell%20activation" title=" T-cell activation"> T-cell activation</a> </p> <a href="https://publications.waset.org/abstracts/137155/in-vitro-modulation-of-cytokine-expression-by-an-aqueous-licorice-extract-in-canine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137155.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">121</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">51</span> Molecular Detection of Tuberculosis in Dogs in the Three North-Eastern States Assam, Mizoram and Nagaland of India </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20G.%20Barua">A.

MTB, the primary agent of human tuberculosis (TB), can develop clinical TB in animals as 75 percent of canine mycobacterial infection is caused by close contact with an infected human being. In the present study, molecular detection of TB in dogs in three North-eastern states of India, Assam Mizoram, and Nagaland was carried out. So far, there has been a lack of systematic study in these regions, hampered by slow diagnostic methods and poor infrastructure. In an attempt to rectify this situation, molecular epidemiology was carried out for nine months to detect canine TB in a sample of 340 dogs. Isolation of DNA was done with swabs (throat/nasal), nodules of lungs and fluids from 100 suspected dogs and the molecular study were carried out with the help of conventional and real-time PCR. Post-mortem study was also carried out. Our results showed that the prevalence of clinical TB in dogs from a high-risk setting was 1 percent. However, the prevalence of immunological sensitization to M. tuberculosis antigen in dogs living in contact with sputum smeared positive TB cases was almost 50 percent. The latter setting had the maximum impact in terms of TB transmission. During the study period, a survey with a standard questionnaire was carried out in the TB hospitals to study reverse zoonosis. It was observed that an infected human being was one of the major risk factors for dogs to contract the infection. This observation was drawn by examining the probable airborne transmission from humans to their pets or strays. The present study helped to discover the nuances of TB transmission more clearly and systematically as compared to other sporadic tests to detect MTB in canine. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Assam%20and%20Nagaland" title="Assam and Nagaland">Assam and Nagaland</a>, <a href="https://publications.waset.org/abstracts/search?q=canine%20TB" title=" canine TB"> canine TB</a>, <a href="https://publications.waset.org/abstracts/search?q=India" title=" India"> India</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20detection" title=" molecular detection"> molecular detection</a>, <a href="https://publications.waset.org/abstracts/search?q=tuberculosis" title=" tuberculosis"> tuberculosis</a> </p> <a href="https://publications.waset.org/abstracts/117497/molecular-detection-of-tuberculosis-in-dogs-in-the-three-north-eastern-states-assam-mizoram-and-nagaland-of-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117497.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">144</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">50</span> Intensive Crosstalk between Autophagy and Intracellular Signaling Regulates Osteosarcoma Cell Survival Response under Cisplatin Stress</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jyothi%20Nagraj">Jyothi Nagraj</a>, <a href="https://publications.waset.org/abstracts/search?q=Sudeshna%20Mukherjee"> Sudeshna Mukherjee</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajdeep%20Chowdhury"> Rajdeep Chowdhury</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Autophagy has recently been linked with cancer cell survival post drug insult contributing to acquisition of resistance. However, the molecular signaling governing autophagic survival response is poorly explored. In our study, in osteosarcoma (OS) cells cisplatin shock was found to activate both MAPK and autophagy signaling. An activation of JNK and autophagy acted as pro-survival strategy, while ERK1/2 triggered apoptotic signals upon cisplatin stress. An increased sensitivity of the cells to cisplatin was obtained with simultaneous inhibition of both autophagy and JNK pathway. Furthermore, we observed that the autophagic stimulation upon drug stress regulates other developmentally active signaling pathways like the Hippo pathway in OS cells. Cisplatin resistant cells were thereafter developed by repetitive drug exposure followed by clonal selection. Basal levels of autophagy were found to be high in resistant cells to. However, the signaling mechanism leading to autophagic up-regulation and its regulatory effect differed in OS cells upon attaining drug resistance. Our results provide valuable clues to regulatory dynamics of autophagy that can be considered for development of improved therapeutic strategy against resistant type cancers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=JNK" title="JNK">JNK</a>, <a href="https://publications.waset.org/abstracts/search?q=autophagy" title=" autophagy"> autophagy</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20resistance" title=" drug resistance"> drug resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer" title=" cancer"> cancer</a> </p> <a href="https://publications.waset.org/abstracts/63712/intensive-crosstalk-between-autophagy-and-intracellular-signaling-regulates-osteosarcoma-cell-survival-response-under-cisplatin-stress" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63712.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">290</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">49</span> Production of Recombinant VP2 Protein of Canine Parvovirus Type 2c Using Baculovirus Expression System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jae%20Young%20Song">Jae Young Song</a>, <a href="https://publications.waset.org/abstracts/search?q=In-Ohk%20Ouh"> In-Ohk Ouh</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyeon%20Park"> Seyeon Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Byeong%20Sul%20Kang"> Byeong Sul Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Soo%20Dong%20Cho"> Soo Dong Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=In-Soo%20Cho"> In-Soo Cho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Canine parvovirus (CPV) is a major pathogen of diarrhea disease in dogs. CPV type 2 has three of antigenic variants such as 2a, 2b, and 2c. CPV constructs a small non-enveloped, icosahedral capsid that contains single-stranded DNA. It has capsids that two largely overlapping virion proteins (VP), VP1 (82 kDa), and VP2 (65 kDa). Baculoviruses are insect pathogens that regulate insect populations in nature and are being successfully used to control insect pests. The proteins produced in the baculovirus-expression system are used for instance for functional studies, vaccine preparations, or diagnostics. The vaccines produced by baculovirus-expression system showed elicitation of antibodies. The recombinant baculovirus infected SF9 cells showed broken shape. The recombinant VP2 proteins from cell pellet or supernatant were confirmed by western blotting. The result showed that the recombinant VP2 protein bands were appeared at 65 kDa molecular weight in both cell pellet and supernatant of infected SF9 cell. These results indicated that the recombinant baculovirus infected SF9 cell express the recombinant VP2 protein successfully. In addition, the expressed recombinant VP2 protein is secreted from cell to supernatant. The baculovirus expression system can be used to produce the VP2 protein of CPV 2c. In addition, the secretion property of the expression of VP2 protein may decrease the cost of production, because it can be skipped the cell breaking step. The produced VP2 protein could be used for vaccine and the agent of diagnostic tests. This study provides the foundation of the production of CPV 2c vaccine and the diagnostic agent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=baculovirus" title="baculovirus">baculovirus</a>, <a href="https://publications.waset.org/abstracts/search?q=canine%20parvovirus%202c" title=" canine parvovirus 2c"> canine parvovirus 2c</a>, <a href="https://publications.waset.org/abstracts/search?q=dog" title=" dog"> dog</a>, <a href="https://publications.waset.org/abstracts/search?q=Korea" title=" Korea"> Korea</a> </p> <a href="https://publications.waset.org/abstracts/93353/production-of-recombinant-vp2-protein-of-canine-parvovirus-type-2c-using-baculovirus-expression-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93353.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">48</span> The Incidence of Maxillary Canine Ankylosis: A Single-Centre Analysis of 206 Canines Following Surgical Exposure and Orthodontic Alignment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sidra%20Suleman">Sidra Suleman</a>, <a href="https://publications.waset.org/abstracts/search?q=Maliha%20Suleman"> Maliha Suleman</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinesh%20Shah"> Jinesh Shah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Maxillary canines play a crucial role in occlusion and aesthetics. Successful management of impacted canines requires early identification and intervention to prevent complications such as resorption of adjacent teeth and cystic changes. Although removal of the deciduous canine can encourage normal eruption of its successor, this is not always successful. Some patients may require surgical exposure and bonding of a gold chain to mobilise and align the canine, which can take up to 3 years. As this procedure has various risks, patients need to be appropriately consented to. Failure of such treatment commonly occurs due to inadequate anchorage or failure of the gold chain attachment, but in some cases, this is due to ankylosis. Aim: The aim of this study was to determine the incidence of ankylosis of unerupted maxillary ectopic canines following surgical exposure and orthodontic alignment at the Maxillofacial and Orthodontic Department, Royal Stoke University Hospital (RSUH), United Kingdom. Methodology: Patients treated from January 1, 2017, to December 31, 2019, were retrospectively studied. Electronic records with post-treatment follow-up at 3-6 months and 12-15 months were extracted and analysed. Patients were excluded based on three criteria, non-compliance with orthodontic treatment post-surgery, presence of canine transposition, and external orthodontic treatment. Sample: Overall, 159 suitable patients were selected from the 171 patients identified. Surgical exposure and gold chain bonding was carried out for a total of 206 maxillary canines, with the pattern of impaction being 159 (77.2 %) palatal, 46 (22.3%) buccal, and 1 (0.49%) in line of the arch. The sample consisted of 57 (35.8%) males and 102 (64.2%) females between the age range of 10 to 32 years, with the mean age being 15 years. The procedures were carried out under general anaesthesia for all but three patients, with two cases being repeats. Closed exposure was carried out for 189 (91.7%) canines. Results: The incidence of ankylosis from this study was 0.97%. In total, two patients had upper left canine ankylosis, which was identified at their 12-15 months orthodontic follow-up. Both patients were males, one having closed exposure at age 15 and the other having open exposure at age 19. Conclusions: Although this data shows that there is a low risk of ankylosis (0.97%), it highlights the difficulty in predicting which patients may be affected, and thus, a thorough pre-treatment assessment and careful observation during treatment is necessary. Future studies involving larger cohorts are warranted to further analyse factors affecting outcomes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ankylosis" title="ankylosis">ankylosis</a>, <a href="https://publications.waset.org/abstracts/search?q=ectopic" title=" ectopic"> ectopic</a>, <a href="https://publications.waset.org/abstracts/search?q=maxillary%20canines" title=" maxillary canines"> maxillary canines</a>, <a href="https://publications.waset.org/abstracts/search?q=orthodontics" title=" orthodontics"> orthodontics</a> </p> <a href="https://publications.waset.org/abstracts/139035/the-incidence-of-maxillary-canine-ankylosis-a-single-centre-analysis-of-206-canines-following-surgical-exposure-and-orthodontic-alignment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139035.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">209</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">47</span> Production, Characterization and In vitro Evaluation of [223Ra]RaCl2 Nanomicelles for Targeted Alpha Therapy of Osteosarcoma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yang%20Yang">Yang Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Luciana%20Magalh%C3%A3es%20Rebelo%20Alencar"> Luciana Magalhães Rebelo Alencar</a>, <a href="https://publications.waset.org/abstracts/search?q=Martha%20Sahyl%C3%AD%20Ortega%20Pijeira"> Martha Sahylí Ortega Pijeira</a>, <a href="https://publications.waset.org/abstracts/search?q=Beatriz%20da%20Silva%20Batista"> Beatriz da Silva Batista</a>, <a href="https://publications.waset.org/abstracts/search?q=Alefe%20Roger%20Silva%20Fran%C3%A7a"> Alefe Roger Silva França</a>, <a href="https://publications.waset.org/abstracts/search?q=Erick%20Rafael%20Dias%20Rates"> Erick Rafael Dias Rates</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruana%20Cardoso%20Lima"> Ruana Cardoso Lima</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Gemini-Piperni"> Sara Gemini-Piperni</a>, <a href="https://publications.waset.org/abstracts/search?q=Ralph%20Santos-Oliveira"> Ralph Santos-Oliveira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Radium-²²³ dichloride ([²²³Rₐ]RₐCl₂) is an alpha particle-emitting radiopharmaceutical currently approved for the treatment of patients with castration-resistant prostate cancer, symptomatic bone metastases, and no known visceral metastatic disease. [²²³Rₐ]RₐCl₂ is bone-seeking calcium mimetic that bonds into the newly formed bone stroma, especially osteoblastic or sclerotic metastases, killing the tumor cells by inducing DNA breaks in a potent and localized manner. Nonetheless, the successful therapy of osteosarcoma as primary bone tumors is still a challenge. Nanomicelles are colloidal nanosystems widely used in drug development to improve blood circulation time, bioavailability, and specificity of therapeutic agents, among other applications. In addition, the enhanced permeability and retention effect of the nanosystems, and the renal excretion of the nanomicelles reported in most cases so far, are very attractive to achieve selective and increased accumulation in tumor site as well as to increase the safety of [²²³Rₐ]RₐCl₂ in the clinical routine. In the present work, [²²³Rₐ]RₐCl₂ nanomicelles were produced, characterized, in vitro evaluated, and compared with pure [²²³Rₐ]RₐCl2 solution using SAOS2 osteosarcoma cells. The [²²³Rₐ]RₐCl₂ nanomicelles were prepared using the amphiphilic copolymer Pluronic F127. The dynamic light scattering analysis of freshly produced [²²³Rₐ]RₐCl₂ nanomicelles demonstrated a mean size of 129.4 nm with a polydispersity index (PDI) of 0.303. After one week stored in the refrigerator, the mean size of the [²²³Rₐ]RₐCl₂ nanomicelles increased to 169.4 with a PDI of 0.381. Atomic force microscopy analysis of [223Rₐ]RₐCl₂ nanomicelles exhibited spherical structures whose heights reach 1 µm, suggesting the filling of 127-Pluronic nanomicelles with [²²³Rₐ]RₐCl₂. The viability assay with [²²³Rₐ]RₐCl₂ nanomicelles displayed a dose-dependent response as it was observed using pure [²²³Rₐ]RₐCl2. However, at the same dose, [²²³Rₐ]RₐCl₂ nanomicelles were 20% higher efficient in killing SAOS2 cells when compared with pure [²²³Rₐ]RₐCl₂. These findings demonstrated the effectiveness of the nanosystem validating the application of nanotechnology in targeted alpha therapy with [²²³Ra]RₐCl₂. In addition, the [²²³Rₐ]RaCl₂nanomicelles may be decorated and incorporated with a great variety of agents and compounds (e.g., monoclonal antibodies, aptamers, peptides) to overcome the limited use of [²²³Ra]RₐCl₂. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanomicelles" title="nanomicelles">nanomicelles</a>, <a href="https://publications.waset.org/abstracts/search?q=osteosarcoma" title=" osteosarcoma"> osteosarcoma</a>, <a href="https://publications.waset.org/abstracts/search?q=radium%20dichloride" title=" radium dichloride"> radium dichloride</a>, <a href="https://publications.waset.org/abstracts/search?q=targeted%20alpha%20therapy" title=" targeted alpha therapy"> targeted alpha therapy</a> </p> <a href="https://publications.waset.org/abstracts/152850/production-characterization-and-in-vitro-evaluation-of-223raracl2-nanomicelles-for-targeted-alpha-therapy-of-osteosarcoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152850.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">117</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">46</span> High Prevalence of Canine Mammary Gland Tumor in Nulliparous Compared with Multiparous Female Dogs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sudson%20Sirivaidyapong">Sudson Sirivaidyapong</a>, <a href="https://publications.waset.org/abstracts/search?q=Ratthanan%20Sathienbumrungkit"> Ratthanan Sathienbumrungkit</a>, <a href="https://publications.waset.org/abstracts/search?q=Nongnapas%20Ruangpet"> Nongnapas Ruangpet</a>, <a href="https://publications.waset.org/abstracts/search?q=Nattanun%20Uaprayoon"> Nattanun Uaprayoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Chawisa%20Wejjakul"> Chawisa Wejjakul </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many factors initiate mammary gland tumor in female dogs such as age, breed, sex, estrous cycle, birth control and pseudopregnancy.

The results revealed that breed, age, birth control age and birth control methods were not different in both groups; most dogs in both groups were various purebreds, geriatric age, and low incidence of hormonal contraception while 100% of multiparous dogs and 83.7% of nulliparous dogs had been neutered at over two years old. The significant differences between two groups were the frequency of pseudopregnancy and estrus which were much higher in nulliparous female dogs. It can be concluded from our study that nulliparous dogs may be more likely at higher risk of mammary tumor compared to multiparous dogs from various factors especially, the frequency of estrus and the occurrence of pseudopregnancy which related to more times of sex hormonal contact. This study was a preliminary data for further studies to determine the other risk factors of mammary gland tumors in dogs, and to our knowledge, it is the first report on a significantly higher prevalence of mammary tumor in nulliparous female dogs than that in multiparous dogs. This finding corresponds with the study of breast cancer in women but may be from different causes and factors due to the differences in estrous physiology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=canine" title="canine">canine</a>, <a href="https://publications.waset.org/abstracts/search?q=female%20dogs" title=" female dogs"> female dogs</a>, <a href="https://publications.waset.org/abstracts/search?q=nulliparous" title=" nulliparous"> nulliparous</a>, <a href="https://publications.waset.org/abstracts/search?q=multiparous" title=" multiparous"> multiparous</a>, <a href="https://publications.waset.org/abstracts/search?q=mammary%20tumor" title=" mammary tumor"> mammary tumor</a>, <a href="https://publications.waset.org/abstracts/search?q=prevalence" title=" prevalence"> prevalence</a> </p> <a href="https://publications.waset.org/abstracts/75486/high-prevalence-of-canine-mammary-gland-tumor-in-nulliparous-compared-with-multiparous-female-dogs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75486.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">471</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> Proteomic Analysis of Cytoplasmic Antigen from Brucella canis to Characterize Immunogenic Proteins Responded with Naturally Infected Dogs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20J.%20Lee">J.

There are, nonetheless, not clear symptoms so that it may go unnoticed in most of the cases. Serodiagnosis for canine brucellosis has not been confirmed. Moreover, it has substantial difficulties due to broad cross-reactivity between the rough cell wall antigens of B. canis and heterospecific antibodies present in normal, uninfected dogs. Thus, this study was conducted to characterize the immunogenic proteins in cytoplasmic antigen (CPAg) of B. canis, which defined the antigenic sensitivity of the humoral antibody responses to B. canis-infected dogs. In analysis of B. canis CPAg, first, we extracted and purified the cytoplasmic proteins from cultured B. canis by hot-saline inactivation, ultrafiltration, sonication, and ultracentrifugation step by step according to the sonicated antigen extract method. For characterization of this antigen, we checked the sort and range of each protein on SDS-PAGE and verified the immunogenic proteins leading to reaction with antisera of B. canis-infected dogs. Selected immunodominant proteins were identified using MALDI-MS/MS. As a result, in an immunoproteomic assay, several polypeptides in CPAg on one or two-dimensional electrophoresis (DE) were specifically reacted to antisera from B. canis-infected dogs but not from non-infected dogs. The polypeptides with approximate 150, 80, 60, 52, 33, 26, 17, 15, 13, 11 kDa on 1-DE were dominantly recognized by antisera from B. canis-infected dogs. In the immunoblot profiles on 2-DE, ten immunodominant proteins in CPAg were detected with antisera of infected dogs between pI 3.5-6.5 at approximate 35 to 10 KDa, without any nonspecific reaction with sera in non-infected dogs. Ten immunodominant proteins identified by MALDI-MS/MS were identified as superoxide dismutase, bacteroferritin, amino acid ABC transporter substrate-binding protein, extracellular solute-binding protein family3, transaldolase, 26kDa periplasmic immunogenic protein, Rhizopine-binding protein, enoyl-CoA hydratase, arginase and type1 glyceraldehyde-3-phosphate dehydrogenase. Most of these proteins were determined by their cytoplasmic or periplasmic localization with metabolism and transporter functions. Consequently, this study discovered and identified the prominent immunogenic proteins in B. canis CPAg, highlighting that those antigenic proteins may accomplish a specific serodiagnosis for canine brucellosis. Furthermore, we will evaluate those immunodominant proteins for applying to the advanced diagnostic methods with high specificity and accuracy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brucella%20canis" title="Brucella canis">Brucella canis</a>, <a href="https://publications.waset.org/abstracts/search?q=Canine%20brucellosis" title=" Canine brucellosis"> Canine brucellosis</a>, <a href="https://publications.waset.org/abstracts/search?q=cytoplasmic%20antigen" title=" cytoplasmic antigen"> cytoplasmic antigen</a>, <a href="https://publications.waset.org/abstracts/search?q=immunogenic%20proteins" title=" immunogenic proteins"> immunogenic proteins</a> </p> <a href="https://publications.waset.org/abstracts/86209/proteomic-analysis-of-cytoplasmic-antigen-from-brucella-canis-to-characterize-immunogenic-proteins-responded-with-naturally-infected-dogs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86209.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">147</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">44</span> Analysis of Differentially Expressed Genes in Spontaneously Occurring Canine Melanoma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Simona%20Perga">Simona Perga</a>, <a href="https://publications.waset.org/abstracts/search?q=Chiara%20Beltramo"> Chiara Beltramo</a>, <a href="https://publications.waset.org/abstracts/search?q=Floriana%20Fruscione"> Floriana Fruscione</a>, <a href="https://publications.waset.org/abstracts/search?q=Isabella%20Martini"> Isabella Martini</a>, <a href="https://publications.waset.org/abstracts/search?q=Federica%20Cavallo"> Federica Cavallo</a>, <a href="https://publications.waset.org/abstracts/search?q=Federica%20Riccardo"> Federica Riccardo</a>, <a href="https://publications.waset.org/abstracts/search?q=Paolo%20Buracco"> Paolo Buracco</a>, <a href="https://publications.waset.org/abstracts/search?q=Selina%20Iussich"> Selina Iussich</a>, <a href="https://publications.waset.org/abstracts/search?q=Elisabetta%20Razzuoli"> Elisabetta Razzuoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Katia%20Varello"> Katia Varello</a>, <a href="https://publications.waset.org/abstracts/search?q=Lorella%20Maniscalco"> Lorella Maniscalco</a>, <a href="https://publications.waset.org/abstracts/search?q=Elena%20Bozzetta"> Elena Bozzetta</a>, <a href="https://publications.waset.org/abstracts/search?q=Angelo%20Ferrari"> Angelo Ferrari</a>, <a href="https://publications.waset.org/abstracts/search?q=Paola%20Modesto"> Paola Modesto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Human and canine melanoma have common clinical, histologic characteristics making dogs a good model for comparative oncology. The identification of specific genes and a better understanding of the genetic landscape, signaling pathways, and tumor–microenvironmental interactions involved in the cancer onset and progression is essential for the development of therapeutic strategies against this tumor in both species. In the present study, the differential expression of genes in spontaneously occurring canine melanoma and in paired normal tissue was investigated by targeted RNAseq. Material and Methods: Total RNA was extracted from 17 canine malignant melanoma (CMM) samples and from five paired normal tissues stored in RNA-later. In order to capture the greater genetic variability, gene expression analysis was carried out using two panels (Qiagen): Human Immuno-Oncology (HIO) and Mouse-Immuno-Oncology (MIO) and the miSeq platform (Illumina). These kits allow the detection of the expression profile of 990 genes involved in the immune response against tumors in humans and mice. The data were analyzed through the CLCbio Genomics Workbench (Qiagen) software using the Canis lupus familiaris genome as a reference. Data analysis were carried out both comparing the biologic group (tumoral vs. healthy tissues) and comparing neoplastic tissue vs. paired healthy tissue; a Fold Change greater than two and a p-value less than 0.05 were set as the threshold to select interesting genes. Results and Discussion: Using HIO 63, down-regulated genes were detected; 13 of those were also down-regulated comparing neoplastic sample vs. paired healthy tissue. Eighteen genes were up-regulated, 14 of those were also down-regulated comparing neoplastic sample vs. paired healthy tissue. Using the MIO, 35 down regulated-genes were detected; only four of these were down-regulated, also comparing neoplastic sample vs. paired healthy tissue. Twelve genes were up-regulated in both types of analysis. Considering the two kits, the greatest variation in Fold Change was in up-regulated genes. Dogs displayed a greater genetic homology with humans than mice; moreover, the results have shown that the two kits are able to detect different genes. Most of these genes have specific cellular functions or belong to some enzymatic categories; some have already been described to be correlated to human melanoma and confirm the validity of the dog as a model for the study of molecular aspects of human melanoma. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=animal%20model" title="animal model">animal model</a>, <a href="https://publications.waset.org/abstracts/search?q=canine%20melanoma" title=" canine melanoma"> canine melanoma</a>, <a href="https://publications.waset.org/abstracts/search?q=gene%20expression" title=" gene expression"> gene expression</a>, <a href="https://publications.waset.org/abstracts/search?q=spontaneous%20tumors" title=" spontaneous tumors"> spontaneous tumors</a>, <a href="https://publications.waset.org/abstracts/search?q=targeted%20RNAseq" title=" targeted RNAseq"> targeted RNAseq</a> </p> <a href="https://publications.waset.org/abstracts/141871/analysis-of-differentially-expressed-genes-in-spontaneously-occurring-canine-melanoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141871.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">199</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">43</span> Management of Renal Malignancies with IVC Thrombus: Our Experience</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sujeet%20Poudyal">Sujeet Poudyal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Renal cell carcinoma is the most common malignancy associated with Inferior vena cava (IVC) thrombosis. Radical nephrectomy with tumor thrombectomy provides durable cancer-free survival. Other renal malignancies like Wilms’ tumors are also associated with IVC thrombus. We describe our experience with the management of renal malignancies associated with IVC thrombus. Methods: This prospective study included 28 patients undergoing surgery for renal malignancies associated with IVC thrombus from February 2017 to March 2023. Demographics of patients, types of renal malignancy, level of IVC thrombus, intraoperative details, need for venovenous bypass, cardiopulmonary bypass and postoperative outcomes were all documented. Results: Out of a total of 28 patients, 24 patients had clear cell Renal Cell Carcinoma,1 had renal osteosarcoma and 3 patients had Wilms tumor. The levels. of thrombus were II in eight, III in seven, and IV in six patients. The mean age of RCC was 62.81±10.2 years, renal osteosarcoma was 26 years and Wilms tumor was 23 years. There was a need for venovenous bypass in four patients and cardiopulmonary bypass in four patients, and the Postoperative period was uneventful in most cases except for two mortalities, one in Level III due to pneumonia and one in Level IV due to sepsis. All cases followed up till now have no local recurrence and metastasis except one case of RCC with Level IV IVC thrombus, which presented with paraaortic nodal recurrence and is currently managed with sunitinib. Conclusion: The complexity in the management of renal malignancy with IVC thrombus increases with the level of IVC thrombus. As radical nephrectomy with tumor thrombectomy provides durable cancer-free survival in most cases, the surgery should be undertaken in an expert and experienced setup with a strong cardiovascular backup to minimize morbidity and mortality associated with the procedure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=renal%20malignancy" title="renal malignancy">renal malignancy</a>, <a href="https://publications.waset.org/abstracts/search?q=IVC%20thrombus" title=" IVC thrombus"> IVC thrombus</a>, <a href="https://publications.waset.org/abstracts/search?q=radical%20nephrectomy%20with%20tumor%20thrombectomy" title=" radical nephrectomy with tumor thrombectomy"> radical nephrectomy with tumor thrombectomy</a>, <a href="https://publications.waset.org/abstracts/search?q=renal%20cell%20carcinoma" title=" renal cell carcinoma"> renal cell carcinoma</a> </p> <a href="https://publications.waset.org/abstracts/168963/management-of-renal-malignancies-with-ivc-thrombus-our-experience" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168963.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">62</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">42</span> Other End of the Leash: The Volunteer Handlers Perspective of Animal-Assisted Interventions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Julie%20A.%20Carberry">Julie A.

In the past 30 years, there has been a dramatic increase in popularity. AAIs are now part of the lives of persons of all ages in many types of institutions. Anecdotal evidence of the benefits of AAIs have led to widespread adoption, yet there remains a lack of solid research base for support. The research question was, what are the lived experiences of AAI volunteer handlers are? An interpretive phenomenological methodology was used for this qualitative study. Data were collected from 1 - 2 hour-long semi-structured interviews and 1 observational field visit. All interviews were conducted, transcribed, and coded for themes by the principal investigator. Participants must have been an active St. John Ambulance Therapy Dog Program volunteer for a least one year. In total, 14 volunteer handlers, along with some of their dogs, were included. The St. John Ambulance is a not for profit organization that provides training and community services to Canadians. The Therapy Dog Program is 1 of the 4 nationally recognized core community service programs. The program incorporates dogs in the otherwise traditional therapeutic intervention of friendly visitation with clients. The lack of formal objectives and goals, and a trained therapist defines the program as an Animal-Assisted Activity (AAA), which is a type of AAI. Since the animals incorporated are dogs, the program is specifically a Canine-Assisted Activity (CAA), which is a type of Canine-Assisted Intervention (CAI). Six themes emerged from the analysis of the data: (a) a win-win-win situation for all parties involved – volunteer handlers, clients, and the dogs, (b) being on the other end of the leash: functions of the role of volunteer handler, (c) the importance of socialization: from spreading smiles to creating meaningful connections, (d) the role of the dog: initiating interaction and providing comfort, (e) an opportunity to feel good and destress, and (f) altruism versus personal rewards. Other insights were found regarding the program, clients, and staff. Possible implications from this research include increased organizational recruitment and retention of volunteer handlers and as well as increased support for CAAs and other CAIs that incorporate teams of volunteer handlers and their dogs. This support could, in turn, add overall support for the acceptance and broad implementation of AAIs as an alternative and or complementary non-pharmaceutical therapeutic intervention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=animal-assisted%20activity" title="animal-assisted activity">animal-assisted activity</a>, <a href="https://publications.waset.org/abstracts/search?q=animal-assisted%20intervention" title=" animal-assisted intervention"> animal-assisted intervention</a>, <a href="https://publications.waset.org/abstracts/search?q=canine-assisted%20activity" title=" canine-assisted activity"> canine-assisted activity</a>, <a href="https://publications.waset.org/abstracts/search?q=canine-assisted%20intervention" title=" canine-assisted intervention"> canine-assisted intervention</a>, <a href="https://publications.waset.org/abstracts/search?q=perspective" title=" perspective"> perspective</a>, <a href="https://publications.waset.org/abstracts/search?q=qualitative" title=" qualitative"> qualitative</a>, <a href="https://publications.waset.org/abstracts/search?q=volunteer%20handler" title=" volunteer handler"> volunteer handler</a> </p> <a href="https://publications.waset.org/abstracts/126021/other-end-of-the-leash-the-volunteer-handlers-perspective-of-animal-assisted-interventions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126021.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">139</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> Association between Bottle-Feeding Habit and Occlusal Disorders in Children 4-6 Years Old</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Roberta%20S.%20Ilinsky">Roberta S.

The aim of this study was to investigate the effect of low-level LASER irradiation on congenital septal defects in dogs. Subjects and Methodology: six male dogs who have congenital septal defects in their hearts -with age ranged 6-10 months- enrolled in this study for one and half months. They were assigned into two groups: Group (A): The study group consisted of 3 canine hearts who received routine animal care associated with LASER irradiation. Group (B): The control group consisted of 3 canine hearts who received only routine animal care. Sizes of the septal defects were measured for both groups at the beginning and after the end of the study. Results: There was a significant decrease in the size of the diameter of the congenital septal defect with the study group (percentage of improvement was 42.19%) when compared with control group. Conclusion: It was concluded that low-level LASER therapy can be considered as a promising therapy for congenital heart defects in animals and to be examined on children with similar congenital lesions after then. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laser" title="laser">laser</a>, <a href="https://publications.waset.org/abstracts/search?q=congenital%20septal%20defects" title=" congenital septal defects"> congenital septal defects</a>, <a href="https://publications.waset.org/abstracts/search?q=dogs" title=" dogs"> dogs</a>, <a href="https://publications.waset.org/abstracts/search?q=infants" title=" infants"> infants</a> </p> <a href="https://publications.waset.org/abstracts/51648/effect-of-low-level-laser-on-healing-of-congenital-septal-defects-on-dogs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51648.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">280</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">39</span> Comparison of Leeway Space Predictions Using Moyers and Tanaka-Johnston Upper Jaw and Lower Jaw on Batak Tribe Between Male and Female in Elementary School Students in Medan City, Sumatera Utara, Indonesia: A Cross-sectional Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hilda%20Fitria%20Lubis">Hilda Fitria Lubis</a>, <a href="https://publications.waset.org/abstracts/search?q=Erna%20Sulistyawati"> Erna Sulistyawati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: The study aims to compare Leeway space averages between Moyers and Tanaka-Johnston's analysis of elementary school students from the Batak tribe in Medan City.
