Rydygier</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the mitotic delay, poor mitotic index and disappearance of lymphocytes from peripheral blood circulation, assessing the DNA damage after high dose exposure is less effective. Conventional chromosome aberration analysis or cytokinesis-blocked micronucleus assay do not provide an accurate dose estimation or radiosensitivity prediction in doses higher than 6.0 Gy. For this reason, there is a need to establish reliable methods allowing analysis of biological effects after exposure in high dose range i.e., during particle radiotherapy. Lately, Premature Chromosome Condensation (PCC) has become an important method in high dose biodosimetry and a promising treatment modality to cancer patients. The aim of the study was to evaluate the usefulness of drug-induced PCC scoring procedure in an experimental mode, where 100 G2/M cells were analyzed in different dose ranges. To test the consistency of obtained results, scoring was performed by 3 independent persons in the same mode and following identical scoring criteria. Whole-body exposure was simulated in an in vitro experiment by irradiating whole blood collected from healthy donors with 60 MeV protons and 250 keV X-rays, in the range of 4.0 – 20.0 Gy. Drug-induced PCC assay was performed on human peripheral blood lymphocytes (HPBL) isolated after in vitro exposure. Cells were cultured for 48 hours with PHA. Then to achieve premature condensation, calyculin A was added. After Giemsa staining, chromosome spreads were photographed and manually analyzed by scorers. The dose-effect curves were derived by counting the excess chromosome fragments. The results indicated adequate dose estimates for the whole-body exposure scenario in the high dose range for both studied types of radiation. Moreover, compared results revealed no significant differences between scores, which has an important meaning in reducing the analysis time. These investigations were conducted as a part of an extended examination of 60 MeV protons from AIC-144 isochronous cyclotron, at the Institute of Nuclear Physics in Kraków, Poland (IFJ PAN) by cytogenetic and molecular methods and were partially supported by grant DEC-2013/09/D/NZ7/00324 from the National Science Centre, Poland. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cell%20response%20to%20radiation%20exposure" title="cell response to radiation exposure">cell response to radiation exposure</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20induced%20premature%20chromosome%20condensation" title=" drug induced premature chromosome condensation"> drug induced premature chromosome condensation</a>, <a href="https://publications.waset.org/abstracts/search?q=premature%20chromosome%20condensation%20procedure" title=" premature chromosome condensation procedure"> premature chromosome condensation procedure</a>, <a href="https://publications.waset.org/abstracts/search?q=proton%20therapy" title=" proton therapy"> proton therapy</a> </p> <a href="https://publications.waset.org/abstracts/45763/the-usefulness-of-premature-chromosome-condensation-scoring-module-in-cell-response-to-ionizing-radiation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45763.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">352</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> Effects of Different Load on Physiological, Hematological, Biochemical, Cytokines Indices of Zanskar Ponies at High Altitude</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prince%20Vivek">Prince Vivek</a>, <a href="https://publications.waset.org/abstracts/search?q=Vijay%20Kumar%20Bharti"> Vijay Kumar Bharti</a>, <a href="https://publications.waset.org/abstracts/search?q=Deepak%20Kumar"> Deepak Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Rohit%20Kumar"> Rohit Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Kapil%20Nehra"> Kapil Nehra</a>, <a href="https://publications.waset.org/abstracts/search?q=Dhananjay%20Singh"> Dhananjay Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Om%20Prakash%20Chaurasia"> Om Prakash Chaurasia</a>, <a href="https://publications.waset.org/abstracts/search?q=Bhuvnesh%20Kumar"> Bhuvnesh Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> High altitude native people still rely heavily on animal transport for logistic support at eastern and northern Himalayas regions. The prevalent mountainous terrains and rugged region are not suitable for the motorized vehicle to use in logistic transport. Therefore, people required high endurance pack animals for load carrying and riding. So far to the best of our knowledge, no studies have been taken to evaluate the effect of loads on the physiology of ponies in high altitude region. So, in this view, we evaluated variation in physiological, hematological, biochemical, and cytokines indices of Zanskar ponies during load carrying at high altitude. Total twelve (12) of Zanskar ponies, mare, age 4-6 years selected for this study, Feed was offered at 2% of body weight, and water ad libitum. Ponies were divided into three groups; group-A (without load), group-B (60 kg), and group-C (80 kg) of backpack loads. The track was very narrow and slippery with gravel, uneven with a rocky surface and has a steep gradient of 4 km uphill at altitude 3291 to 3500m. When we evaluate these parameters, it is understood that the heart rate, pulse rate, and respiration rate was significantly increased in 80 kg group among the three groups. The hematology parameters viz. hemoglobin significantly increased in 80 kg group on 1st day after load carrying among the three groups which was followed by control and 60 kg whereas, PCV, lymphocytes, monocytes percentage significantly increased however, ESR and eosinophil % significantly decreased in 80 kg group after load carrying on 7th day after load carrying among the three groups which were followed by control and 60 kg group. In biochemical parameters viz. LA, LDH, TP, hexokinase (HK), cortisol (CORT), T3, GPx, FRAP and IL-6 significantly increased in 80 kg group on the 7th day after load carrying among the three groups which were followed by control and 60 kg group. The ALT, ALB, GLB, UR, and UA significantly increased in 80 kg group on the 7th day before and after load carrying among the three groups which were followed by control and 60 kg group. The CRT, AST, and CK-MB were significantly increased in 80 kg group on the 1st and 7th day after load carrying among the three groups which were followed by control and 60 kg group. It has been concluded that, heart rate, respiration rate, hematological indices like PCV, lymphocytes, monocytes, Hb and ESR, biochemical indices like lactic acid, LDH, TP, HK, CORT, T3, ALT, AST and CRT, ALB, GLB, UR, UA, GPx, FRAP and IL-6 are important biomarkers to assess effect of load on animal physiology and endurance. Further, this result has revealed the strong correlation of change in biomarkers level with performance in ponies during load carry. Hence, these parameters might be used for the performance of endurance of Zanskar ponies in the high mountain region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biochemical" title="biochemical">biochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=endurance" title=" endurance"> endurance</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20altitude" title=" high altitude"> high altitude</a>, <a href="https://publications.waset.org/abstracts/search?q=load" title=" load"> load</a>, <a href="https://publications.waset.org/abstracts/search?q=ponies" title=" ponies"> ponies</a> </p> <a href="https://publications.waset.org/abstracts/89435/effects-of-different-load-on-physiological-hematological-biochemical-cytokines-indices-of-zanskar-ponies-at-high-altitude" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89435.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">283</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> Do Immune Organ Weights Indicate Immunomodulation of Polyunsaturated Fatty Acids?</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Al-Khalifa">H.

During an immune response, mature lymphocytes and other immune cells interact with antigens in these tissues. Consequently, the mass of these organs can in some cases indicate immune status. The objective of the current study was to investigate the effect of feeding flaxseed on immune tissue weights. Cobb 500 broiler chickens were fed flaxseed at 15%, the control diet did not contain any flaxseed. Results showed that dietary supplementation with flaxseed did not affect the weights of the spleens of broiler chickens. However, it significantly lowered bursa weights (p<0.01), compared to the control diet. In addition, the bursae were thinner in appearance compared with bursii from chickens fed the control diets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bursa%20of%20fabricius" title="bursa of fabricius">bursa of fabricius</a>, <a href="https://publications.waset.org/abstracts/search?q=flaxseed" title=" flaxseed"> flaxseed</a>, <a href="https://publications.waset.org/abstracts/search?q=spleen" title=" spleen"> spleen</a>, <a href="https://publications.waset.org/abstracts/search?q=thymus" title=" thymus"> thymus</a> </p> <a href="https://publications.waset.org/abstracts/28247/do-immune-organ-weights-indicate-immunomodulation-of-polyunsaturated-fatty-acids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28247.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">444</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> Association between G2677T/A MDR1 Polymorphism with the Clinical Response to Disease Modifying Anti-Rheumatic Drugs in Rheumatoid Arthritis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alan%20Ruiz-Padilla">Alan Ruiz-Padilla</a>, <a href="https://publications.waset.org/abstracts/search?q=Brando%20Villalobos-Villalobos"> Brando Villalobos-Villalobos</a>, <a href="https://publications.waset.org/abstracts/search?q=Yeniley%20Ruiz-Noa"> Yeniley Ruiz-Noa</a>, <a href="https://publications.waset.org/abstracts/search?q=Claudia%20Mendoza-Mac%C3%ADas"> Claudia Mendoza-Macías</a>, <a href="https://publications.waset.org/abstracts/search?q=Claudia%20Palafox-S%C3%A1nchez"> Claudia Palafox-Sánchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Miguel%20Mar%C3%ADn-Rosales"> Miguel Marín-Rosales</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%81lvaro%20Cruz"> Álvaro Cruz</a>, <a href="https://publications.waset.org/abstracts/search?q=Rub%C3%A9n%20Rangel-Salazar"> Rubén Rangel-Salazar </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: In patients with rheumatoid arthritis, resistance or poor response to disease modifying antirheumatic drugs (DMARD) may be a reflection of the increase in g-P. The expression of g-P may be important in mediating the effluence of DMARD from the cell. In addition, P-glycoprotein is involved in the transport of cytokines, IL-1, IL-2 and IL-4, from normal lymphocytes activated to the surrounding extracellular matrix, thus influencing the activity of RA. The involvement of P-glycoprotein in the transmembrane transport of cytokines can serve as a modulator of the efficacy of DMARD. It was shown that a number of lymphocytes with glycoprotein P activity is increased in patients with RA; therefore, P-glycoprotein expression could be related to the activity of RA and could be a predictor of poor response to therapy. Objective: To evaluate in RA patients, if the G2677T/A MDR1 polymorphisms is associated with differences in the rate of therapeutic response to disease-modifying antirheumatic agents in patients with rheumatoid arthritis. Material and Methods: A prospective cohort study was conducted. Fifty seven patients with RA were included. They had an active disease according to DAS-28 (score >3.2). We excluded patients receiving biological agents. All the patients were followed during 6 months in order to identify the rate of therapeutic response according to the American College of Rheumatology (ACR) criteria. At the baseline peripheral blood samples were taken in order to identify the G2677T/A MDR1 polymorphisms using PCR- Specific allele. The fragment was identified by electrophoresis in polyacrylamide gels stained with ethidium bromide. For statistical analysis, the genotypic and allelic frequencies of MDR1 gene polymorphism between responders and non-responders were determined. Chi-square tests as well as, relative risks with 95% confidence intervals (95%CI) were computed to identify differences in the risk for achieving therapeutic response. Results: RA patients had a mean age of 47.33 ± 12.52 years, 87.7% were women with a mean for DAS-28 score of 6.45 ± 1.12. At the 6 months, the rate of therapeutic response was 68.7 %. The observed genotype frequencies were: for G/G 40%, T/T 32%, A/A 19%, G/T 7% and for A/A genotype 2%. Patients with G allele developed at 6 months of treatment, higher rate for therapeutic response assessed by ACR20 compared to patients with others alleles (p=0.039). Conclusions: Patients with G allele of the - G2677T/A MDR1 polymorphisms had a higher rate of therapeutic response at 6 months with DMARD. These preliminary data support the requirement for a deep evaluation of these and other genotypes as factors that may influence the therapeutic response in RA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pharmacogenetics" title="pharmacogenetics">pharmacogenetics</a>, <a href="https://publications.waset.org/abstracts/search?q=MDR1" title=" MDR1"> MDR1</a>, <a href="https://publications.waset.org/abstracts/search?q=P-glycoprotein" title=" P-glycoprotein"> P-glycoprotein</a>, <a href="https://publications.waset.org/abstracts/search?q=therapeutic%20response" title=" therapeutic response"> therapeutic response</a>, <a href="https://publications.waset.org/abstracts/search?q=rheumatoid%20arthritis" title=" rheumatoid arthritis"> rheumatoid arthritis</a> </p> <a href="https://publications.waset.org/abstracts/96486/association-between-g2677ta-mdr1-polymorphism-with-the-clinical-response-to-disease-modifying-anti-rheumatic-drugs-in-rheumatoid-arthritis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96486.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">208</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> Granulomatous Mycoses Fungoides: A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Girum%20Tedla%20Assefa">Girum Tedla Assefa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Granulomatous mycosis fungoides is an extremely rare type of cutaneous T-cell lymphoma (<55 cases reported worldwide). Case report: A 36-year-old female presented with soft tissue atrophy of right lower limb (dermis + hypodermis) of 22 years and plaques over trunk of 3 years duration. Histological examination of a biopsy taken from the atrophied tissue showed a granulomatous reaction with epidermotropic atypical lymphocytes. However, in other areas there were only ﬁndings of conventional MF without granuloma. Conclusion: The diagnosis of a granulomatous mycosis fungoides depends exclusively on the histological demonstration of granulomas. Distinct clinical characteristics are not present. This case highlights the importance of thorough investigation of lipoatrophic skin changes in the adult to exclude underlying causes, including MF. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cutaneous%20lymphoma" title="cutaneous lymphoma">cutaneous lymphoma</a>, <a href="https://publications.waset.org/abstracts/search?q=granulomatous%20skin%20lymphoma" title=" granulomatous skin lymphoma"> granulomatous skin lymphoma</a>, <a href="https://publications.waset.org/abstracts/search?q=mycoses%20fungoides" title=" mycoses fungoides"> mycoses fungoides</a>, <a href="https://publications.waset.org/abstracts/search?q=skin%20atrophy" title=" skin atrophy"> skin atrophy</a> </p> <a href="https://publications.waset.org/abstracts/34215/granulomatous-mycoses-fungoides-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34215.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">371</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> Sublethal Effects of Industrial Effluents on Fish Fingerlings (Clarias gariepinus) from Ologe Lagoon Environs, Lagos, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akintade%20O.%20Adeboyejo">Akintade O.

The fish were cultured in varying concentrations of industrial effluents: 0% (control), 5%, 15%, 25%, and 35%. Trials were carried out in triplicates for twelve (12) weeks. The culture system was a static renewable bioassay and was carried out in the fisheries laboratory of the Lagos State University, Ojo-Lagos. Weekly physico-chemical parameters: Temperature (0C), pH, Conductivity (ppm) and Dissolved Oxygen (DO in mg/l) were measured in each treatment tank. Length (cm) and weight (g) data were obtained weekly and used to calculate various growth parameters: mean weight gain (MWG), percentage weight gain (PWG), daily weight gain (DWG), specific growth rate (SGR) and survival. Haematological (Packed Cell Volume (PCV), Red blood cells (RBC), White Blood Cell (WBC), Neutrophil and Lymphocytes etc) and histological alterations were measured after 12 weeks. The physico-chemical parameters showed that the pH ranged from 7.82±0.25–8.07±0.02. DO range from 1.92±0.66-4.43±1.24 mg/l. The conductivity values increased with increase in concentration of I.E. While the temperature remained stable with mean value range between 26.08±2.14–26.38±2.28. The DO showed significant differences at P<0.05. There was progressive increase in length and weight of fish during the culture period. The fish placed in the control had highest increase in both weight and length while fish in 35% had the least. MWG ranged from 16.59–35.96, DWG is from 0.3–0.48, SGR varied from 1.0–1.86 and survival was 100%. Haematological results showed that C. gariepinus had PCV ranging from 13.0±1.7-27.7±0.6, RBC ranged from 4.7±0.6–9.1±0.1, and Neutrophil ranged from 26.7±4.6–61.0±1.0 amongst others. The highest values of these parameters were obtained in the control and lowest at 35%. While the reverse effects were observed for WBC and lymphocytes. This study has shown that effluents may affect the health status of the test organism and impair vital processes if exposure continues for a long period of time. The histological examination revealed several lesions as expressed by the gills and livers. The histopathology of the gills in the control tanks had normal tissues with no visible lesion, but at higher concentrations, there were: lifting of epithelium, swollen lamellae and gill arch infiltration, necrosis and gill arch destruction. While in the liver: control (0%) show normal liver cells, at higher toxic level, there were: vacoulation, destruction of the hepatic parenchyma, tissue becoming eosinophilic (i.e. tending towards Carcinogenicity) and severe disruption of the hepatic cord architecture. The study has shown that industrial effluents from the study area may affect fish health status and impair vital processes if exposure continues for a long period of time even at lower concentrations (Sublethal). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sublethal%20toxicity" title="sublethal toxicity">sublethal toxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=industrial%20effluents" title=" industrial effluents"> industrial effluents</a>, <a href="https://publications.waset.org/abstracts/search?q=clarias%20gariepinus" title=" clarias gariepinus"> clarias gariepinus</a>, <a href="https://publications.waset.org/abstracts/search?q=ologe%20lagoon" title=" ologe lagoon"> ologe lagoon</a> </p> <a href="https://publications.waset.org/abstracts/9114/sublethal-effects-of-industrial-effluents-on-fish-fingerlings-clarias-gariepinus-from-ologe-lagoon-environs-lagos-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9114.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">610</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> Clinical and Laboratory Diagnosis of Malaria in Surat Thani, Southern Thailand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manas%20Kotepui">Manas Kotepui</a>, <a href="https://publications.waset.org/abstracts/search?q=Chatree%20Ratcha"> Chatree Ratcha</a>, <a href="https://publications.waset.org/abstracts/search?q=Kwuntida%20Uthaisar"> Kwuntida Uthaisar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Malaria infection is still to be considered a major public health problem in Thailand. This study, a retrospective data of patients in Surat Thani Province, Southern Thailand during 2012-2015 was retrieved and analyzed. These data include demographic data, clinical characteristics and laboratory diagnosis. Statistical analyses were performed to demonstrate the frequency, proportion, data tendency, and group comparisons. Total of 395 malaria patients were found. Most of patients were male (253 cases, 64.1%). Most of patients (262 cases, 66.3%) were admitted at 6 am-11.59 am of the day. Three hundred and fifty-five patients (97.5%) were positive with P. falciparum. Hemoglobin, hematocrit, and MCHC between P. falciparum and P. vivax were significant different (P value<0.05).During 2012-2015, prevalence of malaria was highest in 2013. Neutrophils, lymphocytes, and monocytes were significantly changed among patients with fever ≤ 3 days compared with patients with fever >3 days.

Urothelial carcinoma (UC) is the most prevalent subtype among BLCA patients, which can be categorized into muscle-invasive bladder cancer (MIBC) and non-muscle-invasive bladder cancer (NMIBC). Currently, various therapeutic options are available for UC patients, including (1) transurethral resection followed by intravesical instillation of chemotherapeutics or Bacillus Calmette-Guérin for NMIBC patients, (2) neoadjuvant platinum-based chemotherapy (NAC) plus radical cystectomy is the standard of care for localized MIBC patients, and (3) systematic chemotherapy for metastatic UC. However, conventional treatments may lead to several challenges for treating patients. As an illustration, some patients may suffer from recurrence of the disease after the first line of treatment. Recently, immune checkpoint therapy (ICT) has been introduced as an alternative treatment strategy for the first or second line of treatment in advanced or metastatic BLCA patients. Although ICT showed lucrative results for a fraction of BLCA patients, ~80% of patients were not responsive to it. Therefore, novel treatment methods are required to augment the ICI response rate within BLCA patients. It has been shown that the infiltration of T-cells into the tumor microenvironment (TME) is positively correlated with the response to ICT within cancerous patients. Therefore, the goal of this study is to enhance the infiltration of cytotoxic T-cells into TME through the identification of target genes within the tumor that are responsible for the non-T-cell inflamed TME and their inhibition. BLCA bulk RNA-sequencing data from The Cancer Genome Atlas (TCGA) and immune score for TCGA samples were used to determine the Pearson correlation score between the expression of different genes and immune score for each sample. The genes with strong negative correlations were selected (r < -0.2). Thereafter, the correlation between the expression of each gene and survival in BLCA patients was calculated using the TCGA data and Cox regression method. The genes that are common in both selected gene lists were chosen for further analysis. Afterward, BLCA bulk and single-cell RNA-sequencing data were ranked based on the expression of each selected gene and the top and bottom 25% samples were used for pathway enrichment analysis. If the pathways related to the T-cell infiltration (e.g., antigen presentation, interferon, or chemokine pathways) were enriched within the low-expression group, the gene was included for downstream analysis. Finally, the selected genes will be used to calculate the correlation between their expression and the infiltration rate of the activated CD+8 T-cells, natural killer cells and the activated dendric cells. A list of potential target genes has been identified and ranked based on the above-mentioned analysis and criteria. SUN-1 got the highest score within the gene list and other identified genes in the literature as benchmarks. In conclusion, inhibition of SUN1 may increase the tumor-infiltrating lymphocytes and the efficacy of ICI in BLCA patients. BLCA tumor cells with and without SUN-1 CRISPR/Cas9 knockout will be injected into the syngeneic mouse model to validate the predicted SUN-1 effect on increasing tumor-infiltrating lymphocytes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=data%20analysis" title="data analysis">data analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=gene%20expression%20analysis" title=" gene expression analysis"> gene expression analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=gene%20identification" title=" gene identification"> gene identification</a>, <a href="https://publications.waset.org/abstracts/search?q=immunoinformatic" title=" immunoinformatic"> immunoinformatic</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20genomics" title=" functional genomics"> functional genomics</a>, <a href="https://publications.waset.org/abstracts/search?q=transcriptomics" title=" transcriptomics"> transcriptomics</a> </p> <a href="https://publications.waset.org/abstracts/143621/identification-of-the-target-genes-to-increase-the-immunotherapy-response-in-bladder-cancer-patients-using-computational-and-experimental-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143621.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">156</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> Improved Approach to the Treatment of Resistant Breast Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lola%20T.%20Alimkhodjaeva">Lola T.

The essential obstacle to the full anti-tumor therapy implementation is drug resistance development. Taking into account the fact that chemotherapy is main antitumor treatment in BC patients, the important task is to improve treatment results. Certain success in overcoming this situation has been associated with the use of methods of extracorporeal blood treatment (ECBT), plasmapheresis. Materials and Methods: We examined 129 women with resistant BC stages 3-4, aged between 56 to 62 years who had previously received 2 courses of CAF chemotherapy. All patients additionally underwent 2 courses of CAF chemotherapy but against the background ECBT with ultrasonic exposure. We studied the following parameters: 1. The highlights of peripheral blood before and after therapy. 2. The state of cellular immunity and identification of activation markers CD23 +, CD25 +, CD38 +, CD95 + on lymphocytes was performed using monoclonal antibodies. Evaluation of humoral immunity was determined by the level of main classes of immunoglobulins IgG, IgA, IgM in serum. 3. The degree of tumor regression was assessed by WHO recommended 4 gradations. (complete - 100%, partial - more than 50% of initial size, process stabilization–regression is less than 50% of initial size and tumor advance progressing). 4. Medical pathomorphism in the tumor was determined by Lavnikova. 5. The study of immediate and remote results, up to 3 years and more. Results and Discussion: After performing extracorporeal blood treatment anemia occurred in 38.9%, leukopenia in 36.8%, thrombocytopenia in 34.6%, hypolymphemia in 26.8%. Studies of immunoglobulin fractions in blood serum were able to establish a certain relationship between the classes of immunoglobulin A, G, M and their functions. The results showed that after treatment the values of main immunoglobulins in patients’ serum approximated to normal. Analysis of expression of activation markers CD25 + cells bearing receptors for IL-2 (IL-2Rα chain) and CD95 + lymphocytes that were mediated physiological apoptosis showed the tendency to increase, which apparently was due to activation of cellular immunity cytokines allocated by ultrasonic treatment. To carry out ECBT on the background of ultrasonic treatment improved the parameters of the immune system, which were expressed in stimulation of cellular immunity and correcting imbalances in humoral immunity. The key indicator of conducted treatment efficiency is the immediate result measured by the degree of tumor regression. After ECBT performance the complete regression was 10.3%, partial response - 55.5%, process stabilization - 34.5%, tumor advance progressing no observed. Morphological investigations of tumor determined therapeutic pathomorphism grade 2 in 15%, in 25% - grade 3 and therapeutic pathomorphism grade 4 in 60% of patients. One of the main criteria for the effect of conducted treatment is to study the remission terms in the postoperative period (up to 3 years or more). The remission terms up to 3 years with ECBT was 34.5%, 5-year survival was 54%. Carried out research suggests that a comprehensive study of immunological and clinical course of breast cancer allows the differentiated approach to the choice of methods for effective treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title="breast cancer">breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=immunoglobulins" title=" immunoglobulins"> immunoglobulins</a>, <a href="https://publications.waset.org/abstracts/search?q=extracorporeal%20blood%20treatment" title=" extracorporeal blood treatment"> extracorporeal blood treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=chemotherapy" title=" chemotherapy"> chemotherapy</a> </p> <a href="https://publications.waset.org/abstracts/65515/improved-approach-to-the-treatment-of-resistant-breast-cancer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65515.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">274</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> Studying the Antiapoptotic Activity of Β Cells from Cord Blood Based Mesenchymal Stem Cells as an Approach to Treat Diabetes Mellitus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Parcha%20Sreenivasa%20Rao">Parcha Sreenivasa Rao</a>, <a href="https://publications.waset.org/abstracts/search?q=P.%20Lakshmi"> P.

The lack of β cells leads to the reduced insulin levels. The β cell death generally occurs due to apoptosis induced by the several cytokines. IL-1β, IFN- ϒ and TNF –α cytokines that are generally cause apoptosis to the β cell. The nutrient based apoptosis is generally seen with high glucose and free fatty acids. It is also noted that the β cell death triggered by Fas ligand and its receptor Fas at the surface of the activated CD8+ T- lymphocytes. Reports also reveal that the β cell apoptosis is under control of the transcription factors NF-kB and STAT- 1. The arresting or opposing of the β cell apoptosis can be overcome by the different growth factors like GLP-1, growth hormone, prolactin, VEGF, Dipeptidyl peptidase-4, Vildagliptin, suberoylanilidehydroxamic acid, trichistatin-A, XIAP, Bcl-2, FGF-21.

This paper gives an update to patient management and treatment modalities. Folliculitis decalvans is classified as primary neutrophilic cicatricial alopecia and predominantly occurs in middle-aged adults. The cause of folliculitis decalvans (FD) remains unknown. Staphylococcus aureus and a deficient host immune response seem to play an important role in the development of this disfiguring scalp disease. Lesions occur mainly in the vertex and occipital area. Clinically, the lesions present with follicular pustules, lack of ostia, diffuse and perifollicular erythema, follicular tufting, and, oftentimes, hemorrhagic crusts and erosions. Histology displays a mainly neutrophilic inflammatory infiltrate in early lesions and additionally lymphocytes and plasma cells in advanced lesions. Treatment is focused on the eradication of S. aureus and anti-inflammatory agents. Although the etiology of FD is unclear, S. aureus is almost always isolated from affected areas, and eradication is an important part of therapeutic management, in combination with systemic and ⁄ or topical anti-inflammatory treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cicatricial%20alopecia" title="cicatricial alopecia">cicatricial alopecia</a>, <a href="https://publications.waset.org/abstracts/search?q=folliculitis%20decalvans" title=" folliculitis decalvans"> folliculitis decalvans</a>, <a href="https://publications.waset.org/abstracts/search?q=tufted%20folliculitis" title=" tufted folliculitis"> tufted folliculitis</a>, <a href="https://publications.waset.org/abstracts/search?q=erosion" title=" erosion"> erosion</a> </p> <a href="https://publications.waset.org/abstracts/23424/folliculitis-decalvans-update" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23424.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">412</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> Studying the Anti-Cancer Effects of Thymoquinone on Tumor Cells Through Natural Killer Cells Activity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nouf%20A.%20Aldarmahi">Nouf A.

Nigella sativa can be effective in a variety of diseases such as hypertension, diabetes, bronchitis, gastrointestinal upset, and cancer. The anticancer effect of Nigella sativa appeared to be mediated by immune-modulatory effect through stimulating human natural killer (NK) cells. This is a type of lymphocytes which is part of the innate immunity, also known as the first line of defense in the body against pathogens. This study investigated the effect of thymoquinone as a major component of Nigella sativa on the molecular cytotoxic pathway of NK cell and the role of thymoquinone therapeutic effect on NK cells. NK cells were cultured with breast tumor cells in different ways and cultured media was collected and the concentration of perforin, granzyme B and interferon-α were measured by ELISA. The cytotoxic effect of NK cells on breast tumor cells was enhanced in the presence of thymoquinone, with increased activity of perforin in NK cells.

However, less attention has been given to their toxicity effect. Thus, the study is an attempt to examine the protective effect of A. excelsa on the pancreas and to determine possible toxicity mediated by the extract. Diabetes was induced experimentally in rats by high-fat-diet for 16 weeks followed by intraperitoneal injection of streptozotocin at dosage of 35 mg/kg of body weight. Declination of the fasting blood glucose level was observed after continuous administration of A. excelsa for 14 days twice daily. This is due to the refining structure of the pancreas. However, surprisingly, the plant extract reduced the leukocytes, erythrocytes, hemoglobin, MCHC and lymphocytes. In addition, the rat treated with the plant extract exhibited increment in AST and eosinocytes level. Overall, the finding shows that A. excelsa possesses antidiabetic activity by improving the structure of pancreatic islet of Langerhans but involved in ameliorating of hematology and biochemical parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azadirachta%20excelsa" title="Azadirachta excelsa">Azadirachta excelsa</a>, <a href="https://publications.waset.org/abstracts/search?q=diabetes" title=" diabetes"> diabetes</a>, <a href="https://publications.waset.org/abstracts/search?q=pancreas" title=" pancreas"> pancreas</a>, <a href="https://publications.waset.org/abstracts/search?q=hemato-biochemical%20parameters" title=" hemato-biochemical parameters"> hemato-biochemical parameters</a> </p> <a href="https://publications.waset.org/abstracts/13139/attenuation-of-pancreatic-histology-hematology-and-biochemical-parameters-in-type-2-diabetic-rats-treated-with-azadirachta-excelsa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13139.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">418</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> Homing of B Cells via Afferent Lymphatics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sara%20Pereira-Nogueira">Sara Pereira-Nogueira</a>, <a href="https://publications.waset.org/abstracts/search?q=Tim%20Worbs"> Tim Worbs</a>, <a href="https://publications.waset.org/abstracts/search?q=Marc%20Permanyer-Bosser"> Marc Permanyer-Bosser</a>, <a href="https://publications.waset.org/abstracts/search?q=Reinhold%20F%C3%B6rster"> Reinhold Förster</a> </p> <p class="card-text"><strong>Abstract:</strong></p> While the entry mechanism of lymphocytes into the lymph node via the blood are well described, it is still largely unknown how cells enter lymph nodes that arrive via afferent lymphatics. In order to address this, our group has established a micro-injection technique in mice through which cells are delivered directly into the lymphatic vessel immediately afferent to the popliteal lymph node. Injected cells can then be tracked via multi-colour fluorescence or 2-photon microscopy, and their localization can be analysed within the popliteal or downstream lymph nodes by immunohistology. Since naïve B cells express the chemokine receptor CXCR5 we intra-lymphatically co-injected B cells derived from wildtype and Cxcr5-deficient mice. While CXCR5 does not play a role in guiding B cells out of the subcapsular sinus, it affects their positioning within the lymph node parenchyma, since CXCR5-deficient B cells are impaired in migrating into the B cell follicle. The knowledge obtained by studying B-cell migration may prove beneficial in clinical settings regarding tumor metastasis or autoimmune diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=afferent%20lymphatics" title="afferent lymphatics">afferent lymphatics</a>, <a href="https://publications.waset.org/abstracts/search?q=B%20cell%20migration" title=" B cell migration"> B cell migration</a>, <a href="https://publications.waset.org/abstracts/search?q=chemokine" title=" chemokine"> chemokine</a>, <a href="https://publications.waset.org/abstracts/search?q=intra-lymphatic%20injection" title=" intra-lymphatic injection"> intra-lymphatic injection</a> </p> <a href="https://publications.waset.org/abstracts/75819/homing-of-b-cells-via-afferent-lymphatics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75819.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">264</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> Radix Saposhnikoviae Suppresses Allergic Contact Dermatitis in Mice by Regulating DCs Activated Th1-Type Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hailiang%20Liu">Hailiang Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yan%20Ni"> Yan Ni</a>, <a href="https://publications.waset.org/abstracts/search?q=Jie%20Zheng"> Jie Zheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaoyan%20Jiang"> Xiaoyan Jiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Min%20Hong"> Min Hong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Allergic contact dermatitis (ACD) is a commonly clinical type IV allergic skin disease, with the pathological features of infiltration by mononuclear cells and tissue necrosis. Traditional Chinese medicine Radix Saposhnikoviae (RS) is traditionally employed to treat exogenous evils, rubella, itching, rheumatism and tetanus. Meanwhile, it is an important component of the commonly used anti-allergy compound. It’s now widely used as an immuno-modulating agent in mixed herbal decoctions to treat inflammation. However, its mechanism of anti-allergy remains unknown. RS was found to reduce ear thickness, as well as the infiltration of eosinophils. The proliferation of T lymphocytes was inhibited significantly by RS, markedly decreased IFN-γ levels in the supernatant of cells cultured and serum were detected with the treatment of RS. RS significantly decreased the amount of DCs in the mouse lymph nodes, and inhibited the expression of CD4 0 and CD86. Meanwhile, T-bet mRNA expression was down remarkably regulated by RS. These results indicate that RS cures Th1-induced allergic skin inflammation by regulating Th1/Th2 balance with decreasing Th1 differentiation, which might be associated with DCs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=allergic%20contact%20dermatitis" title="allergic contact dermatitis">allergic contact dermatitis</a>, <a href="https://publications.waset.org/abstracts/search?q=Radix%20saposhnikoviae" title=" Radix saposhnikoviae"> Radix saposhnikoviae</a>, <a href="https://publications.waset.org/abstracts/search?q=dendritic%20cells" title=" dendritic cells"> dendritic cells</a>, <a href="https://publications.waset.org/abstracts/search?q=T-bet" title=" T-bet"> T-bet</a>, <a href="https://publications.waset.org/abstracts/search?q=GATA-3" title=" GATA-3"> GATA-3</a>, <a href="https://publications.waset.org/abstracts/search?q=CD4%2B%20CD25%2B%20Foxp3%2B%20treg%20cells" title=" CD4+ CD25+ Foxp3+ treg cells "> CD4+ CD25+ Foxp3+ treg cells </a> </p> <a href="https://publications.waset.org/abstracts/3023/radix-saposhnikoviae-suppresses-allergic-contact-dermatitis-in-mice-by-regulating-dcs-activated-th1-type-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3023.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">374</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 Multiple Sclerosis and the Role of Human Herpesvirus 6 in Its Progression</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sina%20Mahdavi">Sina Mahdavi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and Objective: Multiple sclerosis (MS) is an inflammatory autoimmune disease of the CNS that affects the myelination process in the central nervous system (CNS). Complex interactions of various "environmental or infectious" factors may act as triggers in autoimmunity and disease progression. The association between viral infections, especially Human Herpesvirus 6 (HHV-6), and MS is one potential cause that is not well understood. In this study, we aim to summarize the available data on HHV-6 infection in MS disease progression. Materials and Methods: For this study, the keywords "Multiple sclerosis", " Human Herpesvirus 6 ", and "central nervous system" in the databases PubMed and Google Scholar between 2017 and 2022 were searched, and 12 articles were chosen, studied, and analyzed. Results: HHV 6 tends towards TCD 4+ lymphocytes and enters the CNS due to the weakening of the blood-brain barrier due to inflammatory damage. Following the observation that the HHV-6 U24 protein has a seven amino acid sequence with myelin basic protein, which is one of the main components of the myelin sheath, it could cause a molecular mimicry mechanism followed by cross-reactivity. Reactivation of HHV-6 in the CNS can cause the release of proinflammatory cytokines, including TNF-α, leading to immune-mediated demyelination in patients with MS. Conclusion: There is a high expression of endogenous retroviruses during the course of MS, which indicates the relationship between HHV-6 and MS, and that this virus can play a role in the development of MS by creating an inflammatory state. Therefore, measures to modulate the expression of HHV-6 may be effective in reducing inflammatory processes in demyelinated areas of MS patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multiple%20sclerosis" title="multiple sclerosis">multiple sclerosis</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20herpesvirus%206" title=" human herpesvirus 6"> human herpesvirus 6</a>, <a href="https://publications.waset.org/abstracts/search?q=central%20nervous%20system" title=" central nervous system"> central nervous system</a>, <a href="https://publications.waset.org/abstracts/search?q=autoimmunity" title=" autoimmunity"> autoimmunity</a> </p> <a href="https://publications.waset.org/abstracts/159261/the-multiple-sclerosis-and-the-role-of-human-herpesvirus-6-in-its-progression" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159261.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">111</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> Haplotypes of the Human Leukocyte Antigen-G Different HIV-1 Groups from the Netherlands</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Alyami">A.

To date, 16 untranslated regions (UTR) HLA-G haplotypes have been previously defined by sequenced SNPs in the coding region. From these, UTR-1, UTR-2, UTR-3, UTR-4, UTR-5, UTR-6 and UTR-7 are the most frequent 3’UTR haplotypes at the global level. UTR-1 is associated with higher levels of soluble HLA-G and HLA-G expression, whereas UTR-5 and UTR-7 are linked with low levels of soluble HLA-G and HLA-G expression. Human immunodeficiency virus type 1 (HIV-1) infection results in the progressive loss of immune function in infected individuals. The virus escape mechanism typically includes T lymphocytes and NK cell recognition and lyses by classical HLA-A and B down-regulation, which has been associated with non-classical HLA-G molecule up-regulation, respectively. We evaluated the haplotypes of the HLA-G 3′ untranslated region frequencies observed in three HIV-1 groups from the Netherlands and their susceptibility to develop infection. The three groups are made up of mainly men who have sex with men (MSM), injection drug users (IDU) and a high-risk-seronegative (HRSN) group. DNA samples were amplified with published primers prior sequencing. According to our results, the low expresser frequencies show higher in HRSN compared to other groups. This is indicating that 3’UTR polymorphisms may be identified as potential prognostic biomarkers to determine susceptibility to HIV. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Human%20leukocyte%20antigen-G%20%28HLA-G%29" title="Human leukocyte antigen-G (HLA-G) ">Human leukocyte antigen-G (HLA-G) </a>, <a href="https://publications.waset.org/abstracts/search?q=men%20who%20have%20sex%20with%20men%20%28MSM%29" title=" men who have sex with men (MSM)"> men who have sex with men (MSM)</a>, <a href="https://publications.waset.org/abstracts/search?q=injection%20drug%20users%20%28IDU%29" title=" injection drug users (IDU)"> injection drug users (IDU)</a>, <a href="https://publications.waset.org/abstracts/search?q=high-risk-seronegative%20%28HRSN%29%20group" title=" high-risk-seronegative (HRSN) group"> high-risk-seronegative (HRSN) group</a>, <a href="https://publications.waset.org/abstracts/search?q=high-untranslated%20region%20%28UTR%29" title=" high-untranslated region (UTR) "> high-untranslated region (UTR) </a> </p> <a href="https://publications.waset.org/abstracts/76538/haplotypes-of-the-human-leukocyte-antigen-g-different-hiv-1-groups-from-the-netherlands" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76538.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">153</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> Immunologically Non-Treated Vascular Xenografts in Long-Term Survival Animals </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=W.%20G.%20Kim">W.

For immunologically non-treated xenografts, bilateral porcine carotid arteries were harvested, and after short-term freezing at -70°C, were implanted into goats. The preparation of acellularized xenograft vessels has been performed with Nacl-SDS solution and stored at the freezer until use. The goats were randomly assigned for three periods of observation (3, 6, and 12 months after implantation), four animals were observed at each of these times. Periodic ultrasonographic examinations were performed during observation period. Following the predetermined periods, the explanted grafts were analyzed. Among 12 animals, one goat died prematurely, and a total of 22 grafts were evaluated. Gross observations revealed non-thrombotic patent smooth lumens. Microscopic examinations of the explanted grafts showed satisfactory cellular reconstruction up to the 12-month observation period. The proportions of CD3 positive T lymphocytes among inflammatory cells infiltrations were very low. In conclusion, these findings, as a whole, suggest that porcine vessel xenografts can be clinically acceptably implanted in the goats as a form of small-diameter vascular graft, regardless of the acellularized xenograft or immunologically non-treated xenograft. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=xenograft" title="xenograft">xenograft</a>, <a href="https://publications.waset.org/abstracts/search?q=arterial%20graft" title=" arterial graft"> arterial graft</a>, <a href="https://publications.waset.org/abstracts/search?q=long-term%20survival%20animals" title=" long-term survival animals"> long-term survival animals</a>, <a href="https://publications.waset.org/abstracts/search?q=immunology" title=" immunology"> immunology</a> </p> <a href="https://publications.waset.org/abstracts/9211/immunologically-non-treated-vascular-xenografts-in-long-term-survival-animals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9211.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">349</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> Current Approach in Biodosimetry: Electrochemical Detection of DNA Damage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcela%20Jelicova">Marcela Jelicova</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Lierova"> Anna Lierova</a>, <a href="https://publications.waset.org/abstracts/search?q=Zuzana%20Sinkorova"> Zuzana Sinkorova</a>, <a href="https://publications.waset.org/abstracts/search?q=Radovan%20Metelka"> Radovan Metelka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> At present, electrochemical methods are used in various research fields, especially for analysis of biological molecules. The fact offers the possibility of using the detection of oxidative damage induced indirectly by γ rays in DNA in biodosimentry. The main goal of our study is to optimize the detection of 8-hydroxyguanine by differential pulse voltammetry. The level of this stable and specific indicator of DNA damage could be determined in DNA isolated from peripheral blood lymphocytes, plasma or urine of irradiated individuals. Screen-printed carbon electrodes modified with carboxy-functionalized multi-walled carbon nanotubes were utilized for highly sensitive electrochemical detection of 8-hydroxyguanine. Electrochemical oxidation of 8-hydroxoguanine monitored by differential pulse voltammetry was found pH-dependent and the most intensive signal was recorded at pH 7. After recalculating the current density, several times higher sensitivity was attained in comparison with already published results, which were obtained using screen-printed carbon electrodes with unmodified carbon ink. Subsequently, the modified electrochemical technique was used for the detection of 8-hydroxoguanine in calf thymus DNA samples irradiated by 60Co gamma source in the dose range from 0.5 to 20 Gy using by various types of sample pretreatment and measurement conditions. This method could serve for fast retrospective quantification of absorbed dose in cases of accidental exposure to ionizing radiation and may play an important role in biodosimetry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodosimetry" title="biodosimetry">biodosimetry</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20detection" title=" electrochemical detection"> electrochemical detection</a>, <a href="https://publications.waset.org/abstracts/search?q=voltametry" title=" voltametry"> voltametry</a>, <a href="https://publications.waset.org/abstracts/search?q=8-hydroxyguanine" title=" 8-hydroxyguanine"> 8-hydroxyguanine</a> </p> <a href="https://publications.waset.org/abstracts/97358/current-approach-in-biodosimetry-electrochemical-detection-of-dna-damage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97358.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">274</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> Cimifugin Inhibited Th2-Type Allergic Contact Dermatitis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xiaoyan%20Jiang">Xiaoyan Jiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Huizhu%20Wang"> Huizhu Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Lili%20Gui"> Lili Gui</a>, <a href="https://publications.waset.org/abstracts/search?q=Dandan%20Shen"> Dandan Shen</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiao%20Wei"> Xiao Wei</a>, <a href="https://publications.waset.org/abstracts/search?q=Xi%20Yu"> Xi Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Hailiang%20Liu"> Hailiang Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Min%20Hong"> Min Hong </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: Applicate FITC to establish Th2-type allergic contact dermatitis model, and study the effect and mechanism of Cimifugin on Th2-type allergic contact dermatitis.

Sixteen wrestlers (weight = 75/45 ± 12/92 kg, age = 22/29 ± 0/90 years, BMI = 26/23 ± 2/64 kg/m²) were randomly divided into two groups: control (water), glucose (2 gr per kg body weight). Blood samples were obtained before, immediately, and 90 minutes of the post-exercise recovery period. Glucose (2 g/kg of body weight, 1W/5V) and water (equal volumes) solutions were given immediately after the second blood sampling. Data were analyzed by using an ANOVA (a repeated measure) and a suitable post hoc test (LSD). A significant decrease was observed in lymphocytes glycogen immediately after exercise (P < 0.001). In the experimental group, increase Lymphocyte glycogen concentration (P < 0.028) than in the control group in 90 min post-exercise.

Tissue biopsy is an established procedure for tumor cell sampling that aids diagnosis, tumor grading, and prediction of prognosis. We studied and compared the levels of liquid biopsy markers in patients with different grades of glioma. Also, it tried to establish the potential association between glioma and specific blood groups antigen. Result: 78 patients were identified, among whom maximum percentage with glioblastoma possessed blood group O+ (53.8%). The second highest frequency had blood group A+ (20.4%), followed by B+ (9.0%) and A- (5.1%), and least with O-. Liquid biopsy biomarkers comprised of ALT, LDH, lymphocytes, Urea, Alkaline phosphatase, AST Neutrophils, and CRP. The levels of all the components increased significantly with the severity of glioma, with maximum levels seen in glioblastoma (grade IV), followed by grade III and grade II respectively. Conclusion: Gliomas possess significant clinical challenges due to their progression with heterogeneous nature and aggressive behavior. Liquid biopsy is a non-invasive approach which aids to establish the status of the patient and determine the tumor grade, therefore may show diagnostic and prognostic utility. Additionally, our study provides evidence to demonstrate the role of ABO blood group antigens in the development of glioma. However, future clinical research on liquid biopsy will improve the sensitivity and specificity of these tests and validate their clinical usefulness to guide treatment approaches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GBM%3A%20glioblastoma%20multiforme" title="GBM: glioblastoma multiforme">GBM: glioblastoma multiforme</a>, <a href="https://publications.waset.org/abstracts/search?q=CT%3A%20computed%20tomography" title=" CT: computed tomography"> CT: computed tomography</a>, <a href="https://publications.waset.org/abstracts/search?q=MRI%3A%20magnetic%20resonance%20imaging" title=" MRI: magnetic resonance imaging"> MRI: magnetic resonance imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=ctRNA%3A%20circulating%20tumor%20RNA" title=" ctRNA: circulating tumor RNA"> ctRNA: circulating tumor RNA</a> </p> <a href="https://publications.waset.org/abstracts/185991/liquid-biopsy-and-screening-biomarkers-in-glioma-grading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185991.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">51</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> Growth Performance and Blood Characteristics of Broilers Chicken Fed on Diet Containing Brewer Spent Grain at Finisher Phase</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=O.%20A.%20Anjola">O.

Three hundred and fifteen (4 weeks old) Oba – Marshall Broilers were used for the experiment. Five experimental diets were formulated with diet 1 (T1) containing 100% soya bean meal as the control, Diet 2, 3, 4 and 5 had BSG as replacement for soya bean meal at 0%, 36%, 57%, 76% and 100% respectively. The birds were allocated into each dietary group in a completely randomized design with 63 chicks in 3 replicates of 21 chicks each. The birds were offered these diets ad libitum from four weeks old to nine weeks old (35 days). Feed intake, body weight, weight gain, and feed conversion ratio (FCR) were assessed. Blood samples were also collected to examine the effect of BSG waste on hematology and serum biochemistry of broilers. Result indicated that BSG did not significantly (P>0.05) affect feed intake and weight gain. However, FCR and final weight of finishing broilers differs significantly (P<0.05) among treatments. The blood hematology and serum biochemistry indices did not follow a particular trend. Cholesterol concentration reduced with increasing level of BSG in the diet. Hb, RBC, WBC, neutrophils, lymphocytes, heterophiles and MCHC were significant (P<0.05) while MHC and MVC were not significantly (P>0.05) affected by BSG in diets. serum total protein, albumin, and cholesterol concentration also showed significance (P<0.05) difference. Thus, BSG can replace soya bean meal up to 14% in the broiler finisher diet without deleterious effect on the growth, hematology and the serum biochemistry of broiler chicken. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=broilers" title="broilers">broilers</a>, <a href="https://publications.waset.org/abstracts/search?q=growth%20performance" title=" growth performance"> growth performance</a>, <a href="https://publications.waset.org/abstracts/search?q=haematology" title=" haematology"> haematology</a>, <a href="https://publications.waset.org/abstracts/search?q=serum%20biochemistry" title=" serum biochemistry"> serum biochemistry</a> </p> <a href="https://publications.waset.org/abstracts/41982/growth-performance-and-blood-characteristics-of-broilers-chicken-fed-on-diet-containing-brewer-spent-grain-at-finisher-phase" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41982.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">349</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">40</span> Inflammatory Changes in Postmenopausal Women including Th17 and Treg</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ae%20Ra%20Han">Ae Ra Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Seoung%20Eun%20Huh"> Seoung Eun Huh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ji%20Yeon%20Kim"> Ji Yeon Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Joanne%20Kwak-Kim"> Joanne Kwak-Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung%20Ki%20Lee"> Sung Ki Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: Prevalence of osteoporosis, cardiovascular disorders, and Alzheimer's disease rapidly increase after menopause. Immune activation and inflammation are suggested as an important pathogenesis of these serious diseases. Several pro-inflammatory cytokines are increased in women with surgical or natural menopause. However, the little is known about IL-17 producing T cells and Foxp3+ regulatory T (Treg) cells in post-menopause. Methods: A total of 34 postmenopausal women, who had no active cardiovascular, endocrine and infectious disorders were recruited as study group and healthy premenopausal women participated as controls. Peripheral blood mononuclear cells were isolated. Immuno-morphologic (CD3, CD4, CD8, CD19, CD56/CD16), intracellular cytokine (TNF-alpha, IFN-gamma, IL-10, IL-17), and Treg cell (Foxp3) studies were carried out using flow cytometry. The proportion of peripheral lymphocytes, including IL-17 producing and Foxp3+ Treg cells immune cell in each group were statistically analyzed. Results: The proportion of NK cells was significantly increased in menopausal women as compared to that of controls (P=.005). The ratios of TNF-alpha/IL-10 producing CD3+CD4+ T cells were increased in postmenopausal women. CD3+IL-17+ T cell level was higher in postmenopausal women and CD4+ Foxp3+ Treg cells was lower than that of controls. The ratios of CD3+IL-17+ T cell to CD3+Foxp3+ and to CD4+Foxp3+ Treg cells were significantly increased in postmenopausal women (P=.001). Conclusions: We found enhanced innate immunity and Th1- and Th17-mediated adaptive immunity in postmenopausal women. This may explain increasing prevalence of chronic inflammatory diseases after menopause. Further studies are needed to elucidate what factors contribute to this inflammatory shift in the postmenopause. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inflammation" title="inflammation">inflammation</a>, <a href="https://publications.waset.org/abstracts/search?q=immune%20cell" title=" immune cell"> immune cell</a>, <a href="https://publications.waset.org/abstracts/search?q=menopause" title=" menopause"> menopause</a>, <a href="https://publications.waset.org/abstracts/search?q=Th17" title=" Th17"> Th17</a>, <a href="https://publications.waset.org/abstracts/search?q=regulatory%20T%20cell" title=" regulatory T cell"> regulatory T cell</a> </p> <a href="https://publications.waset.org/abstracts/51106/inflammatory-changes-in-postmenopausal-women-including-th17-and-treg" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51106.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">323</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> Development of Programmed Cell Death Protein 1 Pathway-Associated Prognostic Biomarkers for Bladder Cancer Using Transcriptomic Databases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shu-Pin%20Huang">Shu-Pin Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Pai-Chi%20Teng"> Pai-Chi Teng</a>, <a href="https://publications.waset.org/abstracts/search?q=Hao-Han%20Chang"> Hao-Han Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chia-Hsin%20Liu"> Chia-Hsin Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yung-Lun%20Lin"> Yung-Lun Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Shu-Chi%20Wang"> Shu-Chi Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsin-Chih%20Yeh"> Hsin-Chih Yeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Chih-Pin%20Chuu"> Chih-Pin Chuu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiun-Hung%20Geng"> Jiun-Hung Geng</a>, <a href="https://publications.waset.org/abstracts/search?q=Li-Hsin%20Chang"> Li-Hsin Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei-Chung%20Cheng"> Wei-Chung Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Chia-Yang%20Li"> Chia-Yang Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The emergence of immune checkpoint inhibitors (ICIs) targeting proteins like PD-1 and PD-L1 has changed the treatment paradigm of bladder cancer. However, not all patients benefit from ICIs, with some experiencing early death. There's a significant need for biomarkers associated with the PD-1 pathway in bladder cancer. Current biomarkers focus on tumor PD-L1 expression, but a more comprehensive understanding of PD-1-related biology is needed. Our study has developed a seven-gene risk score panel, employing a comprehensive bioinformatics strategy, which could serve as a potential prognostic and predictive biomarker for bladder cancer. This panel incorporates the FYN, GRAP2, TRIB3, MAP3K8, AKT3, CD274, and CD80 genes. Additionally, we examined the relationship between this panel and immune cell function, utilizing validated tools such as ESTIMATE, TIDE, and CIBERSORT. Our seven-genes panel has been found to be significantly associated with bladder cancer survival in two independent cohorts. The panel was also significantly correlated with tumor infiltration lymphocytes, immune scores, and tumor purity. These factors have been previously reported to have clinical implications on ICIs. The findings suggest the potential of a PD-1 pathway-based transcriptomic panel as a prognostic and predictive biomarker in bladder cancer, which could help optimize treatment strategies and improve patient outcomes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bladder%20cancer" title="bladder cancer">bladder cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=programmed%20cell%20death%20protein%201" title=" programmed cell death protein 1"> programmed cell death protein 1</a>, <a href="https://publications.waset.org/abstracts/search?q=prognostic%20biomarker" title=" prognostic biomarker"> prognostic biomarker</a>, <a href="https://publications.waset.org/abstracts/search?q=immune%20checkpoint%20inhibitors" title=" immune checkpoint inhibitors"> immune checkpoint inhibitors</a>, <a href="https://publications.waset.org/abstracts/search?q=predictive%20biomarker" title=" predictive biomarker"> predictive biomarker</a> </p> <a href="https://publications.waset.org/abstracts/173666/development-of-programmed-cell-death-protein-1-pathway-associated-prognostic-biomarkers-for-bladder-cancer-using-transcriptomic-databases" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173666.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">78</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">38</span> Dietary N-6/N-3 PUFA Ratios Affect the Homeostasis of CD4+ T Cells in Mice with Dextran Sulfate Sodium-Induced Colitis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cyoung-Huei%20Huang">Cyoung-Huei Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chiu-Li%20Yeh"> Chiu-Li Yeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Man-Hui%20Pai"> Man-Hui Pai</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung-Ling%20Yeh"> Sung-Ling Yeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study evaluated the effect of different dietary n-6/n-3 polyunsaturated fatty acid (PUFA) ratios on modulating helper T (Th) and regulatory T (Treg) lymphocytes in mice with dextran sulfate sodium (DSS)-induced colitis. There were 3 control and 3 colitis groups in this study. Mice were fed for 24 d with an AIN-93G diet either with soybean oil (S), a mixture of soybean oil and low fish oil content (LF) or high fish oil content (HF). The ratio of n-6/n-3 PUFA in the LF diet was 4:1, and that in the HF diet was 2:1. The control groups drank distilled water while colitis groups provided 2% DSS in drinking water during day 15-19. All mice drank distilled water from day 20-24 for recovery and sacrificed on day 25. The results showed that colitis resulted in higher Th1, Th2, and Th17 and lower Treg percentages in the blood. Also, plasma haptoglobin and proinflammatory chemokines were elevated in colon lavage fluid. Colitic groups with fish oil had lower inflammatory mediators in the plasma and colon lavage fluid. Further, the percentages of Th1, Th2, and Th17 cells in the blood were lower, whereas Treg cell percentages were higher than those in the soybean oil group. The colitis group with n-6/n-3 PUFA ratio 2:1 had more pronounce effects than ratio 4:1. These results suggest that diets with an n-6/n-3 PUFA ratio of 2:1 or 4:1 regulate the Th/Treg balance and attenuate inflammatory mediator production in colitis. Compared to the n-6/n-3 PUFA ratio 4:1, the ratio of 2:1 was more effective in reducing inflammatory reactions in DSS-induced colitis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inflammatory%20bowel%20disease" title="inflammatory bowel disease">inflammatory bowel disease</a>, <a href="https://publications.waset.org/abstracts/search?q=n-3%20polyunsaturated%20fatty%20acids" title=" n-3 polyunsaturated fatty acids"> n-3 polyunsaturated fatty acids</a>, <a href="https://publications.waset.org/abstracts/search?q=helper%20T%20lymphocyte" title=" helper T lymphocyte"> helper T lymphocyte</a>, <a href="https://publications.waset.org/abstracts/search?q=regulatory%20T%20lymphocyte" title=" regulatory T lymphocyte"> regulatory T lymphocyte</a> </p> <a href="https://publications.waset.org/abstracts/23343/dietary-n-6n-3-pufa-ratios-affect-the-homeostasis-of-cd4-t-cells-in-mice-with-dextran-sulfate-sodium-induced-colitis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23343.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">297</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">37</span> Green Tea Extract: Its Potential Protective Effect on Bleomycin Induced Lung Injuries in Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azza%20EL-Medany">Azza EL-Medany</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamila%20EL-Medany"> Jamila EL-Medany</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lung fibrosis is a common side effect of the chemotherapeutic agent, bleomycin. Current evidence suggests that reactive oxygen species may play a key role in the development of lung fibrosis. The present work studied the effect of green tea extract on bleomycin–induced lung fibrosis in rats. Animals were divided into three groups: (1) Saline control group; (2) bleomycin group in which rats were injected with bleomycin (15mg/kg,i.p.) three times a week for four weeks; (3) bleomycin and green tea group in which green tea extract was given to rats (100mg/kg/day, p.o) a week prior to bleomycin and daily during bleomycin injections for 4 weeks until the end of the experiment. Bleomycin–induced pulmonary injury and lung fibrosis that was indicated by increased lung hydroxyproline content, elevated nitric oxide synthase, myeoloperoxidase (MPO), platelet activating factor (PAF), tumor necrosis factor α (TNF_α), transforming growth factor 1β (TGF1β) and angiotensin converting enzyme (ACE) activity in lung tissues. On the other hand, bleomycin induced a reduction in reduced glutathione concentration (GSH). Moreover, bleomycin resulted in a severe histological changes in lung tissues revealed as lymphocytes and neutrophils infiltration, increased collagen deposition and fibrosis. Co-administration of bleomycin and green tea extract reduced bleomycin–induced lung injury as evaluated by the significant reduction in hydroxyproline content, nitric oxide synthase activity, levels of MPO, PAF, TNF-α, and ACE in lung tissues. Furthermore, green tea extract ameliorated bleomycin– induced reduction in GSH concentration. Finally, histological evidence supported the ability of green tea extract to attenuate bleomycin–induced lung fibrosis and consolidation. Thus, the finding of the present study provides that green tea may serve as a novel target for potential therapeutic treatment of lung fibrosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bleomycin" title="bleomycin">bleomycin</a>, <a href="https://publications.waset.org/abstracts/search?q=lung%20fibrosis" title=" lung fibrosis"> lung fibrosis</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20tea" title=" green tea"> green tea</a>, <a href="https://publications.waset.org/abstracts/search?q=oxygen%20species" title=" oxygen species"> oxygen species</a> </p> <a href="https://publications.waset.org/abstracts/15399/green-tea-extract-its-potential-protective-effect-on-bleomycin-induced-lung-injuries-in-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15399.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">452</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">36</span> Redirection of Cytokine Production Patterns by Dydrogesterone, an Orally-Administered Progestogen</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raj%20Raghupathy">Raj Raghupathy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recurrent Spontaneous Miscarriage (RSM) is a common form of pregnancy loss, 50% of which are due to ‘unexplained’ causes. Evidence exists to suggest that RSM may be caused by immunologic factors such as cytokines which are critical molecules of the immune system, with an impressive array of capabilities. An association appears to exist between Th2-type reactivity (mediated by Th2 or anti-inflammatory cytokines) and normal, successful pregnancy, and between unexplained RSM and Th1 cytokine dominance. If pro-inflammatory cytokines are indeed associated with pregnancy loss, the suppression of these cytokines, and thus the ‘redirection’ of maternal reactivity, may help prevent cytokine-mediated pregnancy loss. The objective of this study was to explore the possibility of modulating cytokine production using Dydrogesterone (Duphaston®), an orally-administered progestogen. Peripheral blood mononuclear cells from 34 women with a history of at least 3 unexplained recurrent miscarriages were stimulated in vitro with a mitogen (to elicit cytokine production) in the presence and absence of dydrogesterone. Levels of selected pro- and anti-inflammatory cytokines produced by peripheral blood mononuclear cells were measured after exposure to these progestogens. Dydrogesterone down-regulates the production of pro-inflammatory cytokines and up-regulates the production of anti-inflammatory cytokines. The ratios of Th2 to Th1 cytokines are markedly elevated in the presence of dydrogesterone, indicating a shift from potentially harmful maternal Th1 reactivity to a more pregnancy-conducive Th2 profile. We used a progesterone receptor antagonist to show that this cytokine-modulating effect of dydrogesterone is mediated via the progesterone receptor. Dydrogesterone also induces the production of the Progesterone-Induced Blocking Factor (PIBF); lymphocytes exposed to PIBF produce higher levels of Th2 cytokines, affecting a Th1 → Th2 cytokine shift which could be favourable to the success of pregnancy. We conclude that modulation of maternal cytokine production profiles is possible with dydrogesterone which has the merits that it can be administered orally and that it is safe. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cytokines" title="cytokines">cytokines</a>, <a href="https://publications.waset.org/abstracts/search?q=dydrogesterone" title=" dydrogesterone"> dydrogesterone</a>, <a href="https://publications.waset.org/abstracts/search?q=progesterone" title=" progesterone"> progesterone</a>, <a href="https://publications.waset.org/abstracts/search?q=recurrent%20spontaneous%20miscarriage" title=" recurrent spontaneous miscarriage"> recurrent spontaneous miscarriage</a> </p> <a href="https://publications.waset.org/abstracts/34106/redirection-of-cytokine-production-patterns-by-dydrogesterone-an-orally-administered-progestogen" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34106.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">289</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">35</span> Screening of Selected Medicinal Plants from Jordan for Their Protective Properties against Oxidative DNA Damage and Mutagenecity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karem%20H.%20Alzoubi">Karem H.

Toxic compounds act as environmental agents having various effects, from irritation to death of cells and tissues. A toxic agent is defined an adverse response in a biological system. There is a particular class that produces some kind of alteration in the genetic material or associated components, so they are recognized as genotoxic agents. Within cells, they interact directly or indirectly with DNA, causing mutations or interfere with some enzymatic repair processes or in the genesis or polymerization of proteinaceous material involved in chromosome segregation. An air pollutant may cause or contribute to increased mortality or serious illness and even pose a potential danger to human health.

Tests, reduction of MTT, trypan blue, NRU, comet assay, sister chromatid exchange (SCE) and chromosomal aberrations allowed evidence reduction in cell viability in cell lines CHO-K1 and Jurkat and damage to the DNA from cell line CHOK1, however, no significant effects were observed in the number of SCEs and chromosomal aberrations. The results suggest that PM2.5 material has genotoxic potential and can induce cancer development, as has been suggested in other studies. <p class="card-text"><strong>Keywords:</strong> <a
