between victims and suspects, but to make a deduction of more various facts in cases. Therefore, the aim of this study is to identify criminal tools through secretion on clothes by using amino acid reagents such as Ninhydrin, DFO(1,8-dizafluoren-9-one), 1,2 – IND (1,2-indanedione) which are reacting to skin secretion. For more effective collecting condition, porcine skin which is physiologically similar to human was used. Although there were little differences of shape identification according to sensitivity, amino acid reagents were able to identify the fist, foot, and baseball bat. Furthermore, we conducted the experiments for developmental variations through change over time setting up 5-weeks period including first damage as variation factor, and developing materials in each action through certain reagents. Specimen level of development depending on change over time was identified. As a result, each of initial level of development was seen no changes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hit%20marks" title="hit marks">hit marks</a>, <a href="https://publications.waset.org/abstracts/search?q=amino%20acid%20reagents" title=" amino acid reagents"> amino acid reagents</a>, <a href="https://publications.waset.org/abstracts/search?q=porcine%20skin" title=" porcine skin"> porcine skin</a>, <a href="https://publications.waset.org/abstracts/search?q=criminal%20tool" title=" criminal tool"> criminal tool</a> </p> <a href="https://publications.waset.org/abstracts/65482/development-of-hit-marks-on-clothes-using-amino-acid-reagents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65482.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">263</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">7999</span> Anterior Segment Optical Coherence Tomography Study of Cornea and Tear Film Parameters in Juvenile Systemic Lupus Erythematous Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Salah%20El-Din%20Mahmoud">Mohamed Salah El-Din Mahmoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Hamed"> Ahmed Hamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Asmaa%20Anwar%20Mohamed"> Asmaa Anwar Mohamed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: To study the tear film parameters, total corneal thickness (CT), corneal epithelial thickness and, corneal power in Juvenile systemic lupus erythematosus (JSLE) patients compared to age-matched controls using anterior segment optical coherence tomography (AS-OCT). Methods: This was a cross-sectional study. Study participants were divided into 2 groups: Group A: 75 eyes of JSLE patients, Group B: 75 eyes of healthy controls. Tear meniscus height (TMH), tear meniscus depth (TMD), and tear meniscus area (TMA) were the lower tear meniscus parameters that were measured. The corneal power, CT, and epithelial thickness were all determined automatically. Results: In the JSLE group, the range of age was 10 to 15 years while the control group was 11 to 16 years. TMH, TMA, and TMD were 527.7±46.8, 0.059±0.015 and 343.3±59.9 respectively in JSLE group while 525.4±44.6, 0.058±0.011 and 340.6±58.0 respectively in control group without significant difference (p-value<0.001). The corneal power was 43.3±0.55 in the JSLE while 43.2±0.54 in the control group without significant difference (p-value= 0.407). CT was 551.1±13.5 in JSLE group while 551.2±15.3 in control group without significant difference (p-value= 0.982). Epithelial thickness was 52.66±1.35 in the JSLE group while 52.60±1.36 in the control group without significant difference (p-value= 0.765). Conclusion: We demonstrated no significant difference in tear meniscus dimensions, CT, epithelial thickness, and corneal power in the JSLE patients compared to age-matched controls using AS-OCT. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tear%20film" title="tear film">tear film</a>, <a href="https://publications.waset.org/abstracts/search?q=ASOCT" title=" ASOCT"> ASOCT</a>, <a href="https://publications.waset.org/abstracts/search?q=JSLE" title=" JSLE"> JSLE</a>, <a href="https://publications.waset.org/abstracts/search?q=pachymetry" title=" pachymetry"> pachymetry</a>, <a href="https://publications.waset.org/abstracts/search?q=corneal%20thickness" title=" corneal thickness"> corneal thickness</a> </p> <a href="https://publications.waset.org/abstracts/143829/anterior-segment-optical-coherence-tomography-study-of-cornea-and-tear-film-parameters-in-juvenile-systemic-lupus-erythematous-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143829.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">172</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">7998</span> The Physiological Effect of Cold Atmospheric Pressure Plasma on Cancer Cells, Cancer Stem Cells, and Adult Stem Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeongyeon%20Park">Jeongyeon Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Yeo%20Jun%20Yoon"> Yeo Jun Yoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiyoung%20Seo"> Jiyoung Seo</a>, <a href="https://publications.waset.org/abstracts/search?q=In%20Seok%20Moon"> In Seok Moon</a>, <a href="https://publications.waset.org/abstracts/search?q=Hae%20Jun%20Lee"> Hae Jun Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Kiwon%20Song"> Kiwon Song</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cold Atmospheric Pressure Plasma (CAPP) is defined as a partially ionized gas with electrically charged particles at room temperature and atmospheric pressure. CAPP generates reactive oxygen species (ROS) and reactive nitrogen species (RNS), and has potential as a new apoptosis-promoting cancer therapy. With an annular type dielectric barrier discharge (DBD) CAPP-generating device combined with a helium (He) gas feeding system, we showed that CAPP selectively induced apoptosis in various cancer cells while it promoted proliferation of the adipose tissue-derived stem cell (ASC). The apoptotic effect of CAPP was highly selective toward p53-mutated cancer cells. The intracellular ROS was mainly responsible for apoptotic cell death in CAPP-treated cancer cells. CAPP induced apoptosis even in doxorubicin-resistant cancer cell lines, demonstrating the feasibility of CAPP as a potent cancer therapy. With the same device and exposure conditions to cancer cells, CAPP stimulated proliferation of the ASC, a kind of mesenchymal stem cell that is capable of self-renewing and differentiating into adipocytes, chondrocytes, osteoblasts and neurons. CAPP-treated ASCs expressed the stem cell markers and differentiated into adipocytes as untreated ASCs. The increase of proliferation by CAPP in ASCs was offset by a NO scavenger but was not affected by ROS scavengers, suggesting that NO generated by CAPP is responsible for the activated proliferation in ASCs. Usually, cancer stem cells are reported to be resistant to known cancer therapies. When we applied CAPP of the same device and exposure conditions to cancer cells to liver cancer stem cells (CSCs) that express CD133 and epithelial cell adhesion molecule (EpCAM) cancer stem cell markers, apoptotic cell death was not examined. Apoptotic cell death of liver CSCs was induced by the CAPP generated from a device with an air-based flatten type DBD. An exposure of liver CSCs to CAPP decreased the viability of liver CSCs to a great extent, suggesting plasma be used as a promising anti-cancer treatment. To validate whether CAPP can be a promising anti-cancer treatment or an adjuvant modality to eliminate remnant tumor in cancer surgery of vestibular schwannoma, we applied CAPP to mouse schwannoma cell line SC4 Nf2 ‑/‑ and human schwannoma cell line HEI-193. A CAPP treatment leads to anti-proliferative effect in both cell lines. We are currently studying the molecular mechanisms of differential physiological effect of CAPP; the proliferation of ASCs and apoptosis of various cancer cells and CSCs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cold%20atmospheric%20pressure%20plasma" title="cold atmospheric pressure plasma">cold atmospheric pressure plasma</a>, <a href="https://publications.waset.org/abstracts/search?q=apoptosis" title=" apoptosis"> apoptosis</a>, <a href="https://publications.waset.org/abstracts/search?q=proliferation" title=" proliferation"> proliferation</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer%20cells" title=" cancer cells"> cancer cells</a>, <a href="https://publications.waset.org/abstracts/search?q=adult%20stem%20cells" title=" adult stem cells"> adult stem cells</a> </p> <a href="https://publications.waset.org/abstracts/55506/the-physiological-effect-of-cold-atmospheric-pressure-plasma-on-cancer-cells-cancer-stem-cells-and-adult-stem-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55506.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">282</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">7997</span> Pathways and Mechanisms of Lymphocytes Emigration from Newborn Thymus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olena%20Grygorieva">Olena Grygorieva</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays mechanisms of thymocytes emigration from the thymus to the periphery are investigated actively. We have proposed a hypothesis of thymocytes’ migration from the thymus through lymphatic vessels during periodical short-term local edema. By morphological, hystochemical methods we have examined quantity of lymphocytes, epitelioreticulocytes, mast cells, blood and lymphatic vessels in morpho-functional areas of rats’ thymuses during the first week after birth in 4 hours interval. In newborn and beginning from 8 hour after birth every 12 hours specific density of the thymus, absolute quantity of microcirculatory vessels, especially of lymphatic ones, lymphcyte-epithelial index, quantity of mast cells and their degranulative forms increase. Structure of extracellular matrix, intrathymical microenvironment and lymphocytes’ adhesive properties change. Absolute quantity of small lymphocytes in thymic cortex changes wavy. All these changes are straightly expressed from 0 till 2, from 12 till 16, from 108 till 120 hours of postnatal life. During this periods paravasal lymphatic vessels are stuffed with lymphocytes, i.e. discrete migration of lymphocytes from the thymus occurs. After rapid edema reduction, quantity of lymphatic vessels decrease, they become empty. Therefore, in the thymus of newborn periodical short-term local edema is observed, on its top discrete migration of lymphocytes from the thymus occurs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lymphocytes" title="lymphocytes">lymphocytes</a>, <a href="https://publications.waset.org/abstracts/search?q=lymphatic%20vessels" title=" lymphatic vessels"> lymphatic vessels</a>, <a href="https://publications.waset.org/abstracts/search?q=mast%20cells" title=" mast cells"> mast cells</a>, <a href="https://publications.waset.org/abstracts/search?q=thymus" title=" thymus"> thymus</a> </p> <a href="https://publications.waset.org/abstracts/41730/pathways-and-mechanisms-of-lymphocytes-emigration-from-newborn-thymus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41730.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">225</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">7996</span> Targeting Mre11 Nuclease Overcomes Platinum Resistance and Induces Synthetic Lethality in Platinum Sensitive XRCC1 Deficient Epithelial Ovarian Cancers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adel%20Alblihy">Adel Alblihy</a>, <a href="https://publications.waset.org/abstracts/search?q=Reem%20Ali"> Reem Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Mashael%20Algethami"> Mashael Algethami</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Shoqafi"> Ahmed Shoqafi</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20S.%20Toss"> Michael S.

Platinating agents induce DNA damage which activate Mre11 nuclease directed DNA damage signalling and response (DDR). Upregulation of DDR may promote chemotherapy resistance. Here we have comprehensively evaluated Mre11 in epithelial ovarian cancers. In clinical cohort that received platinum- based chemotherapy (n=331), Mre11 protein overexpression was associated with aggressive phenotype and poor progression free survival (PFS) (p=0.002). In the ovarian cancer genome atlas (TCGA) cohort (n=498), Mre11 gene amplification was observed in a subset of serous tumours (5%) which correlated highly with Mre11 mRNA levels (p<0.0001). Altered Mre11 levels was linked with genome wide alterations that can influence platinum sensitivity. At the transcriptomic level (n=1259), Mre11 overexpression was associated with poor PFS (p=0.003). ROC analysis showed an area under the curve (AUC) of 0.642 for response to platinum-based chemotherapy. Pre-clinically, Mre11 depletion by gene knock down or blockade by small molecule inhibitor (Mirin) reversed platinum resistance in ovarian cancer cells and in 3D spheroid models. Importantly, Mre11 inhibition was synthetically lethal in platinum sensitive XRCC1 deficient ovarian cancer cells and 3D-spheroids. Selective cytotoxicity was associated with DNA double strand break (DSB) accumulation, S-phase cell cycle arrest and increased apoptosis. We conclude that pharmaceutical development of Mre11 inhibitors is a viable clinical strategy for platinum sensitization and synthetic lethality in ovarian cancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MRE11%3B%20XRCC1" title="MRE11; XRCC1">MRE11; XRCC1</a>, <a href="https://publications.waset.org/abstracts/search?q=ovarian%20cancer" title=" ovarian cancer"> ovarian cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=platinum%20sensitization" title=" platinum sensitization"> platinum sensitization</a>, <a href="https://publications.waset.org/abstracts/search?q=synthetic%20lethality" title=" synthetic lethality"> synthetic lethality</a> </p> <a href="https://publications.waset.org/abstracts/151440/targeting-mre11-nuclease-overcomes-platinum-resistance-and-induces-synthetic-lethality-in-platinum-sensitive-xrcc1-deficient-epithelial-ovarian-cancers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151440.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">129</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">7995</span> Characteristics of Children Heart Rhythm Regulation with Acute Respiratory Diseases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20F.%20Zeynalov">D.

However, they do not allow the evaluation of features related to a period of the cardiac cycle, so how electromechanical phenomena during cardiac subphase are characterized by differently directed changes. Therefore, we have proposed a method of subphase analysis of the cardiac cycle, developed in the department of hominal physiology Novosibirsk State Medical University to identify the features of the dispersion subphase of the cardiac cycle. In the present paper we have examined the 5-minute intervals cardiointervalography (CIG) to isolate RR-, QT-, ST-ranges in healthy children and children with acute respiratory diseases (ARD) in comparison. It is known that primary school-aged children suffer at ARD 5-7 times per year. Consequently, it is one of the most relevant problems in pediatrics. It is known that the spectral indices and indices of temporal analysis of heart rate variability are highly sensitive to the degree of intoxication during immunological process. We believe that the use of subphase analysis of heart rate will allow more thoroughly evaluate responsiveness of the child organism during the course of ARD. The study involved 60 primary school-aged children (30 boys and 30 girls). In order to assess heart rhythm regulation, the record CIG was used on the "VNS-Micro" device of Neurosoft Company (Ivanovo) for 5 minutes in the supine position and 5 minutes during active orthostatic test. Subphase analysis of variance QT-interval and ST-segment was performed on the "KardioBOS" software Biokvant Company (Novosibirsk). In assessing the CIG in the supine position and in during orthostasis of children with acute respiratory diseases only RR-intervals are observed typical trend of general biological reactions through pressosensitive compensation mechanisms to lower blood pressure, but compared with healthy children the severity of the changes is different, of sick children are more pronounced indicators of heart rate regulation. But analysis CIG RR-intervals and analysis subphase ST-segment have yielded conflicting trends, which may be explained by the different nature of the intra- and extracardiac influences on regulatory mechanisms that implement the various phases of the cardiac cycle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acute%20respiratory%20diseases" title="acute respiratory diseases">acute respiratory diseases</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiointervalography" title=" cardiointervalography"> cardiointervalography</a>, <a href="https://publications.waset.org/abstracts/search?q=subphase%20analysis" title=" subphase analysis"> subphase analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiac%20cycle" title=" cardiac cycle"> cardiac cycle</a> </p> <a href="https://publications.waset.org/abstracts/43025/characteristics-of-children-heart-rhythm-regulation-with-acute-respiratory-diseases" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43025.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">275</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">7994</span> Comparison of the Performance of GaInAsSb and GaSb Cells under Different Temperature Blackbody Radiations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Liangliang%20Tang">Liangliang Tang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chang%20Xu"> Chang Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Xingying%20Chen"> Xingying Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> GaInAsSb cells probably show better performance than GaSb cells in low-temperature thermophotovoltaic systems due to lower bandgap; however, few experiments proved this phenomenon so far. In this paper, numerical simulation is used to evaluate GaInAsSb and GaSb cells with similar structures under different radiation temperatures. We found that GaInAsSb cells with n-type emitters show slightly higher output power densities compared with that of GaSb cells with n-type emitters below 1,550 K-blackbody radiation, and the power density of the later cells will suppress the formers above this temperature point. During the temperature range of 1,000~2,000 K, the efficiencies of GaSb cells are about twice of GaInAsSb cells if perfect filters are used to prevent the emission of the non-absorbed long wavelength photons. Several parameters that affect the GaInAsSb cell were analyzed, such as doping profiles, thicknesses of GaInAsSb epitaxial layer and surface recombination velocity. The non-p junctions, i.e., n-type emitters are better for GaInAsSb cell fabrication, which is similar to that of GaSb cells. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermophotovoltaic%20cell" title="thermophotovoltaic cell">thermophotovoltaic cell</a>, <a href="https://publications.waset.org/abstracts/search?q=GaSb" title=" GaSb"> GaSb</a>, <a href="https://publications.waset.org/abstracts/search?q=GaInAsSb" title=" GaInAsSb"> GaInAsSb</a>, <a href="https://publications.waset.org/abstracts/search?q=diffused%20emitters" title=" diffused emitters"> diffused emitters</a> </p> <a href="https://publications.waset.org/abstracts/50509/comparison-of-the-performance-of-gainassb-and-gasb-cells-under-different-temperature-blackbody-radiations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50509.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">7993</span> Biological Activities of Flaxseed Peptides (Linusorbs)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Youn%20Young%20Shim">Youn Young Shim</a>, <a href="https://publications.waset.org/abstracts/search?q=Ji%20Hye%20Kim"> Ji Hye Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae%20Youl%20Cho"> Jae Youl Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20J.%20T.%20Reaney"> Martin J.

The flax plant synthesizes an array of biologically active cyclic peptides or linusorbs (LOs, a.k.a. cyclolinopeptides) from three or more ribosome-derived precursors. [1–9-NαC]-linusorb B3 and [1–9-NαC]-linusorb B2, suppress immunity, induce apoptosis in human epithelial cancer cell line (Calu-3) cells, and inhibit T-cell proliferation, but the mechanism of LOs action is unknown. Using gene expression analysis in nematode cultures and human cancer cell lines, we have observed that LOs exert their activity, in part, through induction of apoptosis. Specific LOs’ properties include: 1) distribution throughout the body after flaxseed consumption; 2) induce heat shock protein (HSP) 70A production as an indicator of stress and address the issue in Caenorhabditis elegans (exposure of nematode cultures to [1–9-NαC]-linusorb B3 induced a 30% increase in production of the HSP 70A protein); 3) induce apoptosis in Calu-3 cells; and 4) modulate regulatory genes in microarray analysis. These diverse activities indicate that LOs might induce apoptosis in cancer cells or act as versatile platforms to deliver a variety of biologically active molecules for cancer therapy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flaxseed" title="flaxseed">flaxseed</a>, <a href="https://publications.waset.org/abstracts/search?q=linusorb" title=" linusorb"> linusorb</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20peptide" title=" cyclic peptide"> cyclic peptide</a>, <a href="https://publications.waset.org/abstracts/search?q=orbitides" title=" orbitides"> orbitides</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20shock%20protein" title=" heat shock protein"> heat shock protein</a>, <a href="https://publications.waset.org/abstracts/search?q=apoptosis" title=" apoptosis"> apoptosis</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-cancer" title=" anti-cancer"> anti-cancer</a> </p> <a href="https://publications.waset.org/abstracts/148070/biological-activities-of-flaxseed-peptides-linusorbs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148070.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">137</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">7992</span> Paramecuim as a Model for the Evaluation of Toxicity (Growth, Total Proteins, Respiratory and GSH Bio Marker Changes) Observed after Treatment with Essential Oils Isolated from Artemisia herba-alba Plant of Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bouchiha%20Hanene">Bouchiha Hanene</a>, <a href="https://publications.waset.org/abstracts/search?q=Rouabhi%20Rachid"> Rouabhi Rachid</a>, <a href="https://publications.waset.org/abstracts/search?q=Bouchama%20Khaled"> Bouchama Khaled</a>, <a href="https://publications.waset.org/abstracts/search?q=Djebar%20Berrebbah%20Houraya"> Djebar Berrebbah Houraya</a>, <a href="https://publications.waset.org/abstracts/search?q=Djebar%20Mohamed%20Reda"> Djebar Mohamed Reda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, some natural products such as essentials oils (EOs) have been used in the fields as alternative to synthetic compounds, to minimize the negative impacts to the environment. This fact has led to questions about the possible impact of EOs on ecosystems. Currently in toxicology, the use of alternative models can help to understand the mechanisms of toxic action, at different levels of organization of ecosystems. Algae, protozoa and bacteria form the base of the food chain and protozoan cells are used as bioindicators often of pollution in environment. Unicellular organisms offer the possibility of direct study of independent cells with specific characteristics of individual cells and whole organisms at the same time. This unicellular facilitates the study of physiological processes, and effects of pollutants at the cellular level, which makes it widely used to assess the toxic effects of various xenobiotics. This study aimed to verify the effects of EOs of one famous plant used tremendously in our folk medicine, namely Artemisia herba alba in causing acute toxicity (24 hours) and chronic (15 days) toxicity for model cellular (Paramecium sp). To this end, cellular’s of paramecium were exposed to various concentrations (Three doses were chosen) of EOs extracted from plant (Artemisia herba alba). In the first experiment, the cellular s cultures were exposed for 48 hours to different concentrations to determine the median lethal concentration (DL50). We followed the evolution of physiological parameters (growth), biochemical (total proteins, respiratory metabolism), as well as the variations of a bio marker the GSH. Our results highlighted a light inhibition of the growth of the protozoa as well as a disturbance of the contents of total proteins and a reduction in the reduced rate of glutathione. The polarographic study revealed a stimulation of the consumption of O2 and this at the treated cells. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=essential%20oils" title="essential oils">essential oils</a>, <a href="https://publications.waset.org/abstracts/search?q=protozoa" title=" protozoa"> protozoa</a>, <a href="https://publications.waset.org/abstracts/search?q=bio%20indicators" title=" bio indicators"> bio indicators</a>, <a href="https://publications.waset.org/abstracts/search?q=toxicity" title=" toxicity"> toxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=Growth" title=" Growth"> Growth</a>, <a href="https://publications.waset.org/abstracts/search?q=bio%20marker" title=" bio marker"> bio marker</a>, <a href="https://publications.waset.org/abstracts/search?q=proteins" title=" proteins"> proteins</a>, <a href="https://publications.waset.org/abstracts/search?q=polarographic" title=" polarographic"> polarographic</a> </p> <a href="https://publications.waset.org/abstracts/40445/paramecuim-as-a-model-for-the-evaluation-of-toxicity-growth-total-proteins-respiratory-and-gsh-bio-marker-changes-observed-after-treatment-with-essential-oils-isolated-from-artemisia-herba-alba-plant-of-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40445.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">346</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">7991</span> Identification of Functional T Cell Receptors Reactive to Tumor Antigens from the T Cell Repertoire of Healthy Donors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Isaac%20Quiros-Fernandez">Isaac Quiros-Fernandez</a>, <a href="https://publications.waset.org/abstracts/search?q=Angel%20Cid-Arregui"> Angel Cid-Arregui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tumor-reactive T cell receptors (TCRs) are being subject of intense investigation since they offer great potential in adoptive cell therapies against cancer. However, the identification of tumor-specific TCRs has proven challenging, for instance, due to the limited expansion capacity of tumor-infiltrating T cells (TILs) and the extremely low frequencies of tumor-reactive T cells in the repertoire of patients and healthy donors. We have developed an approach for rapid identification and characterization of neoepitope-reactive TCRs from the T cell repertoire of healthy donors. CD8 T cells isolated from multiple donors are subjected to a first sorting step after staining with HLA multimers carrying the peptide of interest. The isolated cells are expanded for two weeks, after which a second sorting is performed using the same peptide-HLA multimers. The cells isolated in this way are then processed for single-cell sequencing of their TCR alpha and beta chains. Newly identified TCRs are cloned in appropriate expression vectors for functional analysis on Jurkat, NK92, and primary CD8 T cells and tumor cells expressing the appropriate antigen. We have identified TCRs specifically binding HLA-A2 presenting epitopes of tumor antigens, which are capable of inducing TCR-mediated cell activation and cytotoxicity in target cancer cell lines. This method allows the identification of tumor-reactive TCRs in about two to three weeks, starting from peripheral blood samples of readily available healthy donors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cancer" title="cancer">cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=TCR" title=" TCR"> TCR</a>, <a href="https://publications.waset.org/abstracts/search?q=tumor%20antigens" title=" tumor antigens"> tumor antigens</a>, <a href="https://publications.waset.org/abstracts/search?q=immunotherapy" title=" immunotherapy"> immunotherapy</a> </p> <a href="https://publications.waset.org/abstracts/153990/identification-of-functional-t-cell-receptors-reactive-to-tumor-antigens-from-the-t-cell-repertoire-of-healthy-donors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153990.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">69</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">7990</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.

The basic requirements for such scaffolds are biocompatibility, biodegradation, high cell adhesion, which promotes cell proliferation and differentiation. In many cases, synthetic polymers scaffolds have proven advantageous because they are easy to shape, they are tough, and they have high tensile properties. The regeneration of nerve tissue still remains a big challenge for medicine, and neural stem cells provide promising therapeutic potential for cell replacement therapy. However, experiments with stem cells have their limitations, such as low level of cell viability and poor control of cell differentiation. Whereas the study of already differentiated neuronal cell culture obtained from newborn mouse brain is limited only to cell adhesion. The growth and implantation of neuronal culture requires proper scaffolds. Moreover, the polymer scaffolds implants with neuronal cells could demand specific morphology. To date, it has been proposed to use numerous synthetic polymers for these purposes, including polystyrene, polylactic acid (PLA), polyglycolic acid, and polylactide-glycolic acid. Tissue regeneration experiments demonstrated good biocompatibility of PLA scaffolds, despite the hydrophobic nature of the compound. Problem with poor wettability of the PLA scaffold surface could be overcome in several ways: the surface can be pre-treated by poly-D-lysine or polyethyleneimine peptides; roughness and hydrophilicity of PLA surface could be increased by plasma treatment, or PLA could be combined with natural fibers, such as collagen or chitosan. This work presents a study of adhesion of both induced pluripotent stem cells (iPSCs) and mouse primary neuronal cell culture on the polylactide scaffolds of various types: oriented and non-oriented fibrous nonwoven materials and sponges – with and without the effect of plasma treatment and composites with collagen and chitosan. To evaluate the effect of different types of PLA scaffolds on the neuronal differentiation of iPSCs, we assess the expression of NeuN in differentiated cells through immunostaining. iPSCs more effectively differentiate into neurons on PLA scaffolds with high adhesive properties for primary neuronal cells. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PLA%20scaffold" title="PLA scaffold">PLA scaffold</a>, <a href="https://publications.waset.org/abstracts/search?q=neurons" title=" neurons"> neurons</a>, <a href="https://publications.waset.org/abstracts/search?q=neuronal%20differentiation" title=" neuronal differentiation"> neuronal differentiation</a>, <a href="https://publications.waset.org/abstracts/search?q=stem%20cells" title=" stem cells"> stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=polylactid" title=" polylactid"> polylactid</a> </p> <a href="https://publications.waset.org/abstracts/164951/ipscs-more-effectively-differentiate-into-neurons-on-pla-scaffolds-with-high-adhesive-properties-for-primary-neuronal-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164951.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">85</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">7988</span> Gastroprotective Effect of Copper Complex On Indomethacin-Induced Gastric Ulcer In Rats.

Indomethacin induces an injury to gastrointestinal mucosa in experimental animals and humans and their use is associated with a significant risk of hemorrhage, erosions and perforation of both gastric and intestinal ulcers. The anti-inflammatory action of copper complexes is an important activity of their anti-ulcer effect achieved by their intermediary role as a transport form of copper that allow activation of the several copper-dependent enzymes. Therefore, several copper complexes were synthesized and investigated as promising alternative anti-ulcer therapy. Aim of the work: The purpose of this study was to evaluate a copper chelating complex consisting of egg albumin and copper as one of the copper peptides that can be used as anti-inflammatory agent and effective in ameliorates the hazards of the indomethacin on the histological structure of the fundus of the stomach that could be added to raise the efficacy of the currently used simple and cheap gastric anti-inflammatory drug mucogel. Material &methods: This study was carried out on 40 adult male albino rats,divided equally into 4 groups;Group I(control group) received distilled water,Group II(indomethacin treated group) received (25 mg/kg body weight, oral intubation) once, Group III (mucogel treated group)2 mL/rat once daily, oral incubation, Group IV(copper complex group) 1 mL /rat of 30 gm of copper albumin complex was mixed uniformly with mucogel to 100 mL. Treatment has been started six hour after Induction of Ulcers and continued till the 3rd day. The animals sacrificed and was processed for light, transmission electron microscopy(TEM) and immunostaining for inducible nitric oxide synthase(iNOS). Results: Fundic mucosa of group II, showed exfoliation of epithelial cells lining the gland, discontinuity of surface epithelial cells (ulcer formation), vacuolation and detachment of cells, eosinophilic infiltration and congestion of blood vessels in the lamina propria and submucosa. There was thickening and disarrangement of mucosa, weak positive reaction for PAS and marked increase in the collagen fibers lamina propria and the submucosa of the fundus. TEM revealed degeneration of cheif and parietal cells.Marked increase positive reactive of iNOS in all cells of the fundic gland. Group III showed reconstruction of gastric gland with cystic dilatation and vacuolation, moderate decrease of collagen fibers, reduced the intensity of iNOS while in Group IV healthy mucosa with normal surface lining epithelium and fundic glands, strong positive reaction for PAS, marked decrease of collagen fibers and positive reaction for iNOS. TEM revealed regeneration of cheif and parietal cells. Conclusion: Co treatment of copper-albumin complex seems to be useful for gastric ulcer treatment and ameliorates most of hazards of indomethacin. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=copper%20complex" title="copper complex">copper complex</a>, <a href="https://publications.waset.org/abstracts/search?q=gastric%20ulcer" title=" gastric ulcer"> gastric ulcer</a>, <a href="https://publications.waset.org/abstracts/search?q=indomethacin" title=" indomethacin"> indomethacin</a>, <a href="https://publications.waset.org/abstracts/search?q=rat" title=" rat"> rat</a> </p> <a href="https://publications.waset.org/abstracts/27415/gastroprotective-effect-of-copper-complex-on-indomethacin-induced-gastric-ulcer-in-rats-histological-and-immunohistochemical-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27415.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">339</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">7987</span> Effective Tandem Mesh Nebulisation of Pulmonary Vasodilator and Bronchodilators in Critical Respiratory Failure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nathalie%20Bolding">Nathalie Bolding</a>, <a href="https://publications.waset.org/abstracts/search?q=Marta%20Montero"> Marta Montero</a>, <a href="https://publications.waset.org/abstracts/search?q=Joaquim%20Cevallos"> Joaquim Cevallos</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20F.%20Martin-Lazaro"> Juan F.

Objective: To evaluate the response to continuous nebulization of iEPO and intermittent nebulization of Salbutamol/Ipratropium bromide in adults with severe respiratory failure through a double mesh nebulisation in tandem. Methods: This observational study included two mechanical ventilated adults under hourly ventilatory, gasometrical and clinical measurements during 48h. Both had severe respiratory failure treated with continuous iEPO (50 – 200 micrograms/h) and BD (Salbutamol 2.5 mg and Ipratropium bromide 500 mcg every 6 hours) through double mesh nebulisation (Aerogen solo®) placed in tandem in the dry side of the humidificator. The primary endpoints were the variables associated with a positive response to this tandem nebulised therapy (PaFiO2 index, ROX index). Secondary endpoints were laboratory (ABG) clinical and ventilatory variables. Statistical analysis (SPSS v29) included linear regression and ANOVA.

Severe acute respiratory failure had a positive response rate to continuous iEPO and intermittent BD: PaFiO2 increased (7.40 to 30.91; P75: 27%) as well as ROX index (2.91 to 11.43; P75: 33%). There was a linear correlation of improvement between iEPO with PaFiO2 (ANOVA, r=0.393, p<0.002) and ROX (r=0.419, p<0.001). iEPO+BD therapy did not show any complications. Conclusion: Continuous and intermittent mesh tandem nebulisation can be effectively delivered with this method with a positive effect in ventilatory parameters without observed complications. Randomised studies will be able to provide reassurance in this new therapy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tandem" title="tandem">tandem</a>, <a href="https://publications.waset.org/abstracts/search?q=mesh" title=" mesh"> mesh</a>, <a href="https://publications.waset.org/abstracts/search?q=nebulisers" title=" nebulisers"> nebulisers</a>, <a href="https://publications.waset.org/abstracts/search?q=pulmonary" title=" pulmonary"> pulmonary</a>, <a href="https://publications.waset.org/abstracts/search?q=vasoldilators" title=" vasoldilators"> vasoldilators</a>, <a href="https://publications.waset.org/abstracts/search?q=bronchodilators" title=" bronchodilators"> bronchodilators</a>, <a href="https://publications.waset.org/abstracts/search?q=respiratory" title=" respiratory"> respiratory</a>, <a href="https://publications.waset.org/abstracts/search?q=failure" title=" failure"> failure</a> </p> <a href="https://publications.waset.org/abstracts/173820/effective-tandem-mesh-nebulisation-of-pulmonary-vasodilator-and-bronchodilators-in-critical-respiratory-failure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173820.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">83</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">7986</span> In vitro Study on Characterization and Viability of Vero Cell Lines after Supplementation with Porcine Follicular Fluid Proteins in Culture Medium </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mayuva%20Youngsabanant">Mayuva Youngsabanant</a>, <a href="https://publications.waset.org/abstracts/search?q=Suphaphorn%20Rabiab"> Suphaphorn Rabiab</a>, <a href="https://publications.waset.org/abstracts/search?q=Hatairuk%20Tungkasen"> Hatairuk Tungkasen</a>, <a href="https://publications.waset.org/abstracts/search?q=Nongnuch%20Gumlungpat"> Nongnuch Gumlungpat</a>, <a href="https://publications.waset.org/abstracts/search?q=Mayuree%20Pumipaiboon"> Mayuree Pumipaiboon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The porcine follicular fluid proteins (pFF) of healthy small size ovarian follicles (1-3 mm in diameters) of Large White pig ovaries were collected by sterile technique. They were used for testing the effect on cell viability and characterization of Vero cell lines using MTT assay. Two hundred microliter of round shape Vero cell lines were culture in 96 well plates with DMEM for 24 h. After that, they were attachment to substrate and some changed into fibroblast shape and spread over the surface after culture for 48 h. Then, Vero cell lines were treated with pFF at concentration of 2, 4, 20, 40, 200, 400, 500, and 600 µg proteins/mL for 24 h. Yields of the best results were analyzed by using one-way ANOVA. MTT assay reviewed an increasing in percentage of viability of Vero cell lines indicated that at concentration of 400-600 µg proteins/mL showed higher percentage of viability (115.64 ± 6.95, 106.91 ± 5.27 and 116.73 ± 20.15) than control group. They were significantly different from the control group (p < 0.05) but lower than the positive control group (DMEM with 10% heat treated fetal bovine serum). Cell lines showed normal character in fibroblast elongate shape after treated with pFF except in high concentration of pFF. This result implies that pFF of small size ovarian follicle at concentration of 400-600 µg proteins/mL could be optimized concentration for using as a supplement in Vero cell line culture medium to promote cell viability instead of growth hormone from fetal bovine serum. This merit could be applied in other cell biotechnology researches.

Such tumors could be benign, malignant, or a combination of both. The exact mechanism of origin for collision tumors is predicted to be tumor heterogeneity or concurrent occurrence of neoplasm in the same organ. We present two cases of plasmacytoma presenting as a collision tumor, one with a tumor of hematological origin and another with a non-hematological origin, namely Chronic Lymphocytic Leukemia and Adenocarcinoma of the colon, respectively. The immunohistochemical stains and flowcytometry analysis performed on the specimens aided incorrect diagnosis. Interestingly, neoplastic cells of plasmacytoma in the first case demonstrated strong cytokeratin along with weak Epithelial Specific Antigen/ Epithelial cell adhesion molecule Monoclonal Antibody (MOC31) positivity, indicating that the tumor may influence the microenvironment of the tumor in the vicinity. Furthermore, the next-generation sequencing studies performed on the specimen with plasmacytoma and chronic lymphocytic lymphoma demonstrated BReast CAncer gene (BRCA2) and Tumor Necrosis Factor Alpha Induced Protein 3 (TNFAIP3) as a disease associated variants suggestive of risk for multiple tumors including collision tumors. Our reports highlight the unique collision tumors involving plasmacytoma, which have never been reported previously, as well as provide necessary insights about the underline genetic aberrations and tumor heterogeneity through sequencing studies and allow clonality assessment for subsequent tumors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BRCA2" title="BRCA2">BRCA2</a>, <a href="https://publications.waset.org/abstracts/search?q=collision%20tumor" title=" collision tumor"> collision tumor</a>, <a href="https://publications.waset.org/abstracts/search?q=chronic%20lymphocytic%20leukemia" title=" chronic lymphocytic leukemia"> chronic lymphocytic leukemia</a>, <a href="https://publications.waset.org/abstracts/search?q=plasmacytoma" title=" plasmacytoma"> plasmacytoma</a> </p> <a href="https://publications.waset.org/abstracts/162721/collision-tumor-of-plasmacytoma-with-hematological-and-non-hematological-malignancies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162721.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">190</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">7984</span> Effects of Local Decongestive Agents at Trachea and Lungs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sertac%20Arslan">Sertac Arslan</a>, <a href="https://publications.waset.org/abstracts/search?q=Guven%20Guney"> Guven Guney</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayse%20Ipek%20Akyuz%20Unsal"> Ayse Ipek Akyuz Unsal</a>, <a href="https://publications.waset.org/abstracts/search?q=Emre%20Demir"> Emre Demir</a>, <a href="https://publications.waset.org/abstracts/search?q=Buket%20Demirci"> Buket Demirci</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: There is little histologic data concerning effects of nasal decongestants on the respiratory tract. We aimed to put forth the effects of nasal decongestants on the trachea and lower airways of rats. Materials and Methods: Four to six months old 60 male rats were randomly categorized into 6 groups. Experimental drugs were applied to the same nostril of rats twice daily for 8 weeks (Xylometazolin, Benzalkolyum, EDTA, Sorbitol and combined drug solutions). We applied normal saline solution (NaCl %0.9) for the control group. In the end, trachea and both lungs were dissected and kept in formaldehyde for histopathologic evaluation. Results: Inflammation and bronchial edema were most common findings. While all rats in sorbitol group had increased numbers of type 2 pneumocytes; 80% of BAC group had increased numbers of type 2 pneumocytes. Spillover of tracheal epithelium was seen mostly in sorbitol, EDTA and combined drug groups (60%, 87.5%, 50% respectively). Bronchial smooth muscle hypertrophy was seen mostly in BAC and EDTA group (70%, 62.5% respectively). The number of goblet cells showed the significant difference between control-combined drug (p=0.025) and control-BAC (p=0.001) groups. Conclusions: Nasal decongestants can cause permanent changes at lower respiratory tract in addition to changes in upper respiratory tract. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decongestive%20agents" title="decongestive agents">decongestive agents</a>, <a href="https://publications.waset.org/abstracts/search?q=xylometazoline" title=" xylometazoline"> xylometazoline</a>, <a href="https://publications.waset.org/abstracts/search?q=lung" title=" lung"> lung</a>, <a href="https://publications.waset.org/abstracts/search?q=trachea" title=" trachea"> trachea</a> </p> <a href="https://publications.waset.org/abstracts/88759/effects-of-local-decongestive-agents-at-trachea-and-lungs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88759.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">176</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">7983</span> Development and Evaluation of a Gut-Brain Axis Chip Based on 3D Printing Interconnecting Microchannel Scaffolds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhuohan%20Li">Zhuohan Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Jing%20Yang"> Jing Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yaoyuan%20Cui"> Yaoyuan Cui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The gut-brain axis (GBA), a communication network between gut microbiota and the brain, benefits for investigation of brain diseases. Currently, organ chips are considered one of the potential tools for GBA research. However, most of the available GBA chips have limitations in replicating the three-dimensional (3D) growth environment of cells and lack the required cell types for barrier function. In the present study, a microfluidic chip was developed for GBA interaction. Blood-brain barrier (BBB) module was prepared with HBMEC, HBVP, U87 cells and decellularized matrix (dECM). Intestinal epithelial barrier (IEB) was prepared with Caco-2 and vascular endothelial cells and dECM. GBA microfluidic device was integrated with IEB and BBB modules using 3D printing interconnecting microchannel scaffolds. BBB and IEB interaction on this GBA chip were evaluated with lipopolysaccharide (LPS) exposure. The present GBA chip achieved multicellular three-dimensional cultivation. Compared with the co-culture cell model in the transwell, fluorescein was absorbed more slowly by 5.16-fold (IEB module) and 4.69-fold (BBB module) on the GBA chip. Accumulation of Rhodamine 123 and Hoechst33342 was dramatically decreased. The efflux function of transporters on IEB and BBB was significantly increased on the GBA chip. After lipopolysaccharide (LPS) disrupted the IEB, and then BBB dysfunction was further observed, which confirmed the interaction between IEB and BBB modules. These results demonstrated that this GBA chip may offer a promising tool for gut-brain interaction study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decellularized%20matrix" title="decellularized matrix">decellularized matrix</a>, <a href="https://publications.waset.org/abstracts/search?q=gut-brain%20axis" title=" gut-brain axis"> gut-brain axis</a>, <a href="https://publications.waset.org/abstracts/search?q=organ-on-chip" title=" organ-on-chip"> organ-on-chip</a>, <a href="https://publications.waset.org/abstracts/search?q=three-dimensional%20printing." title=" three-dimensional printing."> three-dimensional printing.</a> </p> <a href="https://publications.waset.org/abstracts/188857/development-and-evaluation-of-a-gut-brain-axis-chip-based-on-3d-printing-interconnecting-microchannel-scaffolds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188857.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">36</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">7982</span> Histogenesis of the Stomach of Pre-Hatching Quail: A Light and Electron Microscopic Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soha%20A%20Soliman">Soha A Soliman</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasser%20A%20Ahmed"> Yasser A Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20A%20Khalaf"> Mohamed A Khalaf</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although the enormous literature describing the histology of the stomach of different avian species during the posthatching development, the available literature on the pre-hatching development of quail stomach development is scanty. Thus, the current study was undertaken to provide a careful description of the main histological events during the embryonic development of quail stomach. To achieve this aim, daily histological specimens from the stomach of quail of 4 days post-incubation till the day 17 (few hours before hatching) were examined with light microscopy. The current study showed that the primitive gut tube of the embryonic quail appeared at the 4th day post incubation, and both parts of stomach (proventriculus and gizzard) were similar in structure and composed of endodermal epithelium of pseudostratified type surrounded by undifferentiated mesenchymal tissue. The sequences of the developmental events in the gut tube were preceded in a cranio-caudal pattern. By the 5th day, the endodermal covering of the primitive proventriculus gave rise to sac-like invaginations. The primitive gizzard was distinguished into thick-walled bodies and thin-walled sacs. In the 6th day, the prospective proventricular glandular epithelium became canalized and the muscular layer was developed in the cranial part of the proventriculus, whereas the primitive muscular coat of the gizzard was represented by a layer of condensed mesenchyme. In the 7th day, the proventricular glandular epithelial invaginations increased in depth and number, while, the muscularis mucosa and the muscular layer began to be distinguished. In the 8th day, the myoblasts differentiated into spindle shaped smooth muscle fibers. In the 10th day, branching of the proventricular glands began. The branching continued later on. The surface and the glandular epithelium were transformed into simple columnar type in the 12th day. The epithelial covering of the gizzard gave rise to tubular invaginations lined by simple cuboidal epithelium and the surface epithelium became simple columnar. Canalization of the tubular glands was recognized in the 14th day. In the 15th day, the proventricular surface epithelium invaginated in an concentric manner around a central cavity to form immature secretory units. The central cavity was lined by eosinophilic cells which form the ductal epithelia. The peripheral lamellae were lined by basophilic cells; the undifferentiated oxyntico-peptic cells. Entero-endocrine cells stained positive for silver impregnation in the proventricular glands. The mucosal folding in the gizzard appeared in the 15th day to form the plicae and the sulci. The wall of the proventriculus and gizzard in the 17th day acquired the main histological features of post-hatching birds, but neither the surface nor the ductal epithelium were differentiated to mucous producing cells. The current results shoed be considered in the molecular developmental studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quail" title="quail">quail</a>, <a href="https://publications.waset.org/abstracts/search?q=proventriculus" title=" proventriculus"> proventriculus</a>, <a href="https://publications.waset.org/abstracts/search?q=gizzard" title=" gizzard"> gizzard</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-hatching" title=" pre-hatching"> pre-hatching</a>, <a href="https://publications.waset.org/abstracts/search?q=histology" title=" histology"> histology</a> </p> <a href="https://publications.waset.org/abstracts/17859/histogenesis-of-the-stomach-of-pre-hatching-quail-a-light-and-electron-microscopic-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17859.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">616</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">7981</span> Effect of Operative Stabilization on Rib Fracture Healing in Porcine Experimental Model: A Pilot Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Stepankova">Maria Stepankova</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucie%20Vistejnova"> Lucie Vistejnova</a>, <a href="https://publications.waset.org/abstracts/search?q=Pavel%20Klein"> Pavel Klein</a>, <a href="https://publications.waset.org/abstracts/search?q=Tereza%20Blassova"> Tereza Blassova</a>, <a href="https://publications.waset.org/abstracts/search?q=Marketa%20Slajerova"> Marketa Slajerova</a>, <a href="https://publications.waset.org/abstracts/search?q=Radek%20Sedlacek"> Radek Sedlacek</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Bartos"> Martin Bartos</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaroslav%20Chlupac"> Jaroslav Chlupac</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Clinical outcome benefits of the segment rib fracture surgical therapy are well known and follow from better stabilization of the chest wall. Despite this, some authors still incline to conservative therapy and point out to possible rib fracture healing failure in connection with the bone vascular supply disturbance caused by metal plate implantation. This suggestion met neither experimental nor clinical verification and remains the object of discussion. In our pilot study we investigated the titanium plate fixation effect on the rib fracture healing in porcine model and its histological, biomechanical and radiological aspects. Materials and Method: Two porcine models (experimental group) underwent the operative chest wall stabilization with a titanium plate implantation after osteotomy. Two other porcine models (control group) were treated conservatively after osteotomy. Three weeks after surgery, all animals were sacrificed, treated ribs were explanted and the histological analysis, µCT imaging and biomechanical testing of the calluses tissue were performed. Results: In µCT imaging, experimental group showed a higher cortical bone volume compared to the control group. Histological analysis using the non-decalcified bone tissue blocks demonstrated more maturated callus with higher newly-formed osseous tissue ratio in experimental group in comparison to controls. In contrast, no significant differences in bone blood vessels supply in both groups were observed. This finding suggests that the bone blood supply in experimental group was not impaired. Biomechanical analysis using 3-point bending test demonstrated significantly higher bending stiffness and the maximum force in experimental group. Conclusion: Based on our observation, it could be concluded, that the titanium plate fixation of the rib fractures leads to faster bone callus maturation whereas does not cause the vascular supply impairment after 3 weeks and thus has a beneficial effect on the rib fracture healing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bone%20vascular%20supply" title="bone vascular supply">bone vascular supply</a>, <a href="https://publications.waset.org/abstracts/search?q=chest%20wall%20stabilization" title=" chest wall stabilization"> chest wall stabilization</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture%20healing" title=" fracture healing"> fracture healing</a>, <a href="https://publications.waset.org/abstracts/search?q=histological%20analysis" title=" histological analysis"> histological analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium%20plate%20implantation" title=" titanium plate implantation"> titanium plate implantation</a> </p> <a href="https://publications.waset.org/abstracts/121410/effect-of-operative-stabilization-on-rib-fracture-healing-in-porcine-experimental-model-a-pilot-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121410.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">141</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">7980</span> Anti-Inflammatory Studies on Chungpye-Tang in Asthmatic Human Lung Tissue</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20H.%20Bang">J.

Genetic and environment factors may result in asthma, but there are no the exact causes of asthma. Chungpye-tang (CPT) has been prescribed as a representative aerosol agent for patients with dyspnea, cough and phlegm in the respiratory clinic at Kyung Hee Korean Medicine Hospital. This Korean herbal medicines have the effect of dispelling external pathogen and dampness pattern. CPT is composed of 4 species of herbal medicines. The 4 species of herbal medicines are Ephedrae herba, Pogostemonis(Agatachis) herba, Caryophylli flos and Zingiberis rhizoma crudus. CPT suppresses neutrophil infiltration and the production of pro-inflammatory cytokines in lipopolysaccharide (LPS)-induced acute lung injury (ALI) mouse model. Moreover, the anti-inflammatory effects of CPT on a mouse model of Chronic Obstructive Pulmonary Disease (COPD) was proved. Activation of the NF-κB has been proven that it plays an important role in inflammation via inducing transcription of pro-inflammatory genes. Over-expression of NF-κB has been believed be related to many inflammatory diseases such as arthritis, gastritis, asthma and COPD. So we firstly hypothesize whether CPT has an anti-inflammatory effect on asthmatic human airway epithelial tissue via inhibiting NF-κB pathway. In this study, CPT was extracted with distilled water for 3 hours at 100°C. After process of filtration and evaporation, it was freeze dried. And asthmatic human lung tissues were provided by MatTek Corp. We investigated the precise mechanism of the anti-inflammatory effect of CPT by western blotting analysis. We observed whether the decoction extracts could reduce NF-κB activation, COX-2 protein expression and NF-κB-mediated pro-inflammatory cytokines such as TNF-α, eotaxin, IL-4, IL-9 and IL-13 in asthmatic human lung tissue. As results of this study, there was a trend toward decreased NF-κB expression in asthmatic human airway epithelial tissue. We found that the inhibition effects of CPT on COX-2 expression was not determined. IL-9 and IL-13 secretion was significantly reduced in the asthmatic human lung tissue treated with CPT. Overall, our results indicate that CPT has an anti-inflammatory effect through blocking the signaling pathway of NF-κB, thereby CPT may be a potential remedial agent for allergic asthma. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chungpye-tang" title="Chungpye-tang">Chungpye-tang</a>, <a href="https://publications.waset.org/abstracts/search?q=allergic%20asthma" title=" allergic asthma"> allergic asthma</a>, <a href="https://publications.waset.org/abstracts/search?q=asthmatic%20human%20airway%20epithelial%20tissue" title=" asthmatic human airway epithelial tissue"> asthmatic human airway epithelial tissue</a>, <a href="https://publications.waset.org/abstracts/search?q=nuclear%20factor%20kappa%20B%20%28NF-%CE%BAB%29%20pathway" title=" nuclear factor kappa B (NF-κB) pathway"> nuclear factor kappa B (NF-κB) pathway</a>, <a href="https://publications.waset.org/abstracts/search?q=COX-2" title=" COX-2"> COX-2</a> </p> <a href="https://publications.waset.org/abstracts/42524/anti-inflammatory-studies-on-chungpye-tang-in-asthmatic-human-lung-tissue" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42524.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">335</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">7979</span> Effect of Surfactant Level of Microemulsions and Nanoemulsions on Cell Viability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sonal%20Gupta">Sonal Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Rakhi%20Bansal"> Rakhi Bansal</a>, <a href="https://publications.waset.org/abstracts/search?q=Javed%20Ali"> Javed Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Reema%20Gabrani"> Reema Gabrani</a>, <a href="https://publications.waset.org/abstracts/search?q=Shweta%20Dang"> Shweta Dang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nanoemulsions (NEs) and microemulsions (MEs) have been an attractive tool for encapsulation of both hydrophilic and lipophillic actives. Both these systems are composed of oil phase, surfactant, co-surfactant and aqueous phase. Depending upon the application and intended use, both oil-in-water and water-in-oil emulsions can be designed. NEs are fabricated using high energy methods employing less percentage of surfactant as compared to MEs which are self assembled drug delivery systems. Owing to the nanometric size of the droplets these systems have been widely used to enhance solubility and bioavailability of natural as well as synthetic molecules. The aim of the present study is to assess the effect of % age of surfactants on cell viability of Vero cells (African Green Monkeys’ Kidney epithelial cells) via MTT assay. Green tea catechin (Polyphenon 60) loaded ME employing low energy vortexing and NE employing high energy ultrasonication were prepared using same excipients (labrasol as oil, cremophor EL as surfactant and glycerol as co-surfactant) however, the % age of oil and surfactant needed to prepare the ME was higher as compared to NE. These formulations along with their excipients (oilME=13.3%, SmixME=26.67%; oilNE=10%, SmixNE=13.52%) were added to Vero cells for 24 hrs. The tetrazolium dye, 3-(4,5-dimethylthia/ol-2-yl)-2,5-diphi-iiyltclrazolium bromide (MTT), is reduced by live cells and this reaction is used as the end point to evaluate the cytoxicity level of a test formulation. Results of MTT assay indicated that oil at different percentages exhibited almost equal cell viability (oilME ≅ oilNE) while surfactant mixture had a significant difference in the cell viability values (SmixME < SmixNE). Polyphenon 60 loaded ME and its PlaceboME showed higher toxicity as compared to Polyphenon 60 loaded NE and its PlaceboNE that can be attributed to the higher concentration of surfactants present in MEs. Another probable reason for high % cell viability of Polyphenon 60 loaded NE might be due to the effective release of Polyphenon 60 from NE formulation that helps in the sustenance of Vero cells. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cell%20viability" title="cell viability">cell viability</a>, <a href="https://publications.waset.org/abstracts/search?q=microemulsion" title=" microemulsion"> microemulsion</a>, <a href="https://publications.waset.org/abstracts/search?q=MTT" title=" MTT"> MTT</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoemulsion" title=" nanoemulsion"> nanoemulsion</a>, <a href="https://publications.waset.org/abstracts/search?q=surfactants" title=" surfactants"> surfactants</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasonication" title=" ultrasonication"> ultrasonication</a> </p> <a href="https://publications.waset.org/abstracts/14115/effect-of-surfactant-level-of-microemulsions-and-nanoemulsions-on-cell-viability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14115.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">436</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">7978</span> Redox-labeled Electrochemical Aptasensor Array for Single-cell Detection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shuo%20Li">Shuo Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Yannick%20Coffinier"> Yannick Coffinier</a>, <a href="https://publications.waset.org/abstracts/search?q=Chann%20Lagadec"> Chann Lagadec</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabrizio%20Cleri"> Fabrizio Cleri</a>, <a href="https://publications.waset.org/abstracts/search?q=Katsuhiko%20Nishiguchi"> Katsuhiko Nishiguchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Akira%20Fujiwara"> Akira Fujiwara</a>, <a href="https://publications.waset.org/abstracts/search?q=Soo%20Hyeon%20Kim"> Soo Hyeon Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Cl%C3%A9ment"> Nicolas Clément</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The need for single cell detection and analysis techniques has increased in the past decades because of the heterogeneity of individual living cells, which increases the complexity of the pathogenesis of malignant tumors. In the search for early cancer detection, high-precision medicine and therapy, the technologies most used today for sensitive detection of target analytes and monitoring the variation of these species are mainly including two types. One is based on the identification of molecular differences at the single-cell level, such as flow cytometry, fluorescence-activated cell sorting, next generation proteomics, lipidomic studies, another is based on capturing or detecting single tumor cells from fresh or fixed primary tumors and metastatic tissues, and rare circulating tumors cells (CTCs) from blood or bone marrow, for example, dielectrophoresis technique, microfluidic based microposts chip, electrochemical (EC) approach. Compared to other methods, EC sensors have the merits of easy operation, high sensitivity, and portability. However, despite various demonstrations of low limits of detection (LOD), including aptamer sensors, arrayed EC sensors for detecting single-cell have not been demonstrated. In this work, a new technique based on 20-nm-thick nanopillars array to support cells and keep them at ideal recognition distance for redox-labeled aptamers grafted on the surface. The key advantages of this technology are not only to suppress the false positive signal arising from the pressure exerted by all (including non-target) cells pushing on the aptamers by downward force but also to stabilize the aptamer at the ideal hairpin configuration thanks to a confinement effect. With the first implementation of this technique, a LOD of 13 cells (with5.4 μL of cell suspension) was estimated. In further, the nanosupported cell technology using redox-labeled aptasensors has been pushed forward and fully integrated into a single-cell electrochemical aptasensor array. To reach this goal, the LOD has been reduced by more than one order of magnitude by suppressing parasitic capacitive electrochemical signals by minimizing the sensor area and localizing the cells. Statistical analysis at the single-cell level is demonstrated for the recognition of cancer cells. The future of this technology is discussed, and the potential for scaling over millions of electrodes, thus pushing further integration at sub-cellular level, is highlighted. Despite several demonstrations of electrochemical devices with LOD of 1 cell/mL, the implementation of single-cell bioelectrochemical sensor arrays has remained elusive due to their challenging implementation at a large scale. Here, the introduced nanopillar array technology combined with redox-labeled aptamers targeting epithelial cell adhesion molecule (EpCAM) is perfectly suited for such implementation. Combining nanopillar arrays with microwells determined for single cell trapping directly on the sensor surface, single target cells are successfully detected and analyzed. This first implementation of a single-cell electrochemical aptasensor array based on Brownian-fluctuating redox species opens new opportunities for large-scale implementation and statistical analysis of early cancer diagnosis and cancer therapy in clinical settings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioelectrochemistry" title="bioelectrochemistry">bioelectrochemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=aptasensors" title=" aptasensors"> aptasensors</a>, <a href="https://publications.waset.org/abstracts/search?q=single-cell" title=" single-cell"> single-cell</a>, <a href="https://publications.waset.org/abstracts/search?q=nanopillars" title=" nanopillars"> nanopillars</a> </p> <a href="https://publications.waset.org/abstracts/171369/redox-labeled-electrochemical-aptasensor-array-for-single-cell-detection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171369.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">7977</span> Differential Infection of Primary Human B-Cells and EBV Positive B-Lymphoma Cell Lines by Recombinant AAV Serotypes </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elham%20Ahmadi">Elham Ahmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehrdad%20Ravanshad"> Mehrdad Ravanshad</a>, <a href="https://publications.waset.org/abstracts/search?q=Joyce%20Fingeroth"> Joyce Fingeroth</a>, <a href="https://publications.waset.org/abstracts/search?q=Mazyar%20Ziyaeyan"> Mazyar Ziyaeyan</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20Panigrahi"> Rajesh Panigrahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jun%20Xie"> Jun Xie</a>, <a href="https://publications.waset.org/abstracts/search?q=Gao%20Guangping"> Gao Guangping</a> </p> <p class="card-text"><strong>Abstract:</strong></p> B-cell proliferative disorders often occur among persons that are T-cell compromised. These disorders are primarily EBV+ and can first present with a focal lesion. Direct introduction of oncolytic viruses into localized tumors provides theoretical advantages over chemotherapy and immunotherapy by reducing systemic toxicity, to which the immunocompromised host is most vulnerable. Widely studied as a vehicle for gene therapy, AAV has only rarely been applied to treat cancer. As a prelude to development of a therapeutic vehicle, we assessed the ability of 15 distinct recombinant AAV serotypes (rAAV1, rAAV2, rAAV3b, rAAV4, rAAV5, rAAV6, rAAV6.2, rAAV6TM, rAAV7, rAAV8, rAAVrh8, rAAV9, rAAVrh10, rAAV39, rAAV43) bearing eGFP to infect human B-cell tumor lines compared with primary B-cells in vitro. Enhanced infection of tumor lines by AAV 6.2 was demonstrated by flow cytometry. EBV superinfection of EBV negative B-cell tumor lines increased susceptibility to AAV6.2 infection. As proof of concept, AAV6.2 bearing HSV-1 thymidine kinase in place of eGFP eliminated tumor cells upon exposure to ganciclovir. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AAV" title="AAV">AAV</a>, <a href="https://publications.waset.org/abstracts/search?q=gene%20therapy" title=" gene therapy"> gene therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=lymphoma" title=" lymphoma"> lymphoma</a>, <a href="https://publications.waset.org/abstracts/search?q=malignancy" title=" malignancy"> malignancy</a>, <a href="https://publications.waset.org/abstracts/search?q=tropism" title=" tropism"> tropism</a> </p> <a href="https://publications.waset.org/abstracts/112865/differential-infection-of-primary-human-b-cells-and-ebv-positive-b-lymphoma-cell-lines-by-recombinant-aav-serotypes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112865.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">120</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">7976</span> Phylogenetic Differential Separation of Environmental Samples</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amber%20C.%20W.%20Vandepoele">Amber C.

Marciano</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biological analyses frequently focus on single organisms, however many times, the biological sample consists of more than the target organism; for example, human microbiome research targets bacterial DNA, yet most samples consist largely of human DNA. Therefore, there would be an advantage to removing these contaminating organisms. Conversely, some analyses focus on a single organism but would greatly benefit from the additional information regarding the other organismal components of the sample. Forensic analysis is one such example, wherein most forensic casework, human DNA is targeted; however, it typically exists in complex non-pristine sample substrates such as soil or unclean surfaces. These complex samples are commonly comprised of not just human tissue but also microbial and plant life, where these organisms may help gain more forensically relevant information about a specific location or interaction. This project aims to optimize a ‘phylogenetic’ differential extraction method that will separate mammalian, bacterial and plant cells in a mixed sample. This is accomplished through the use of size exclusion separation, whereby the different cell types are separated through multiple filtrations using 5 μm filters. The components are then lysed via differential enzymatic sensitivities among the cells and extracted with minimal contribution from the preceding component. This extraction method will then allow complex DNA samples to be more easily interpreted through non-targeting sequencing since the data will not be skewed toward the smaller and usually more numerous bacterial DNAs. This research project has demonstrated that this ‘phylogenetic’ differential extraction method successfully separated the epithelial and bacterial cells from each other with minimal cell loss. We will take this one step further, showing that when adding the plant cells into the mixture, they will be separated and extracted from the sample. Research is ongoing, and results are pending. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DNA%20isolation" title="DNA isolation">DNA isolation</a>, <a href="https://publications.waset.org/abstracts/search?q=geolocation" title=" geolocation"> geolocation</a>, <a href="https://publications.waset.org/abstracts/search?q=non-human" title=" non-human"> non-human</a>, <a href="https://publications.waset.org/abstracts/search?q=phylogenetic%20separation" title=" phylogenetic separation"> phylogenetic separation</a> </p> <a href="https://publications.waset.org/abstracts/122792/phylogenetic-differential-separation-of-environmental-samples" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122792.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">112</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">7975</span> Mannosylated Oral Amphotericin B Nanocrystals for Macrophage Targeting: In vitro and Cell Uptake Studies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rudra%20Vaghela">Rudra Vaghela</a>, <a href="https://publications.waset.org/abstracts/search?q=P.%20K.%20Kulkarni"> P.

AmB Nc were prepared by liquid anti-solvent precipitation technique (LAS). Poloxamer 188 was used to stabilize the prepared AmB Nc and grafted with mannose for actively targeting M cells in Peyer’s patches. To prevent shedding of the stabilizer and ligand, N,N’-Dicyclohexylcarbodiimide (DCC) was used as a cross-linker. The prepared AmB Nc were characterized for particle size, PDI, zeta potential, X-ray diffraction (XRD) and surface morphology using scanning electron microscope (SEM) and evaluated for drug content, in vitro drug release and cell uptake studies using caco-2 cells. The particle size of stabilized AmB Nc grafted with WGA was in the range of 287-417 nm with negative zeta potential between -18 to -25 mV. XRD studies revealed crystalline nature of AmB Nc. SEM studies revealed that ungrafted AmB Nc were irregular in shape with rough surface whereas, grafted AmB Nc were found to be rod-shaped with smooth surface. In vitro drug release of AmB Nc was found to be 86% at the end of one hour. Cellular studies revealed higher invasion and uptake of AmB Nc towards caco-2 cell membrane when compared to ungrafted AmB Nc.

Disruption of the balance among the microbiota, epithelial cells, and resident immune cells in the intestine is involved in the pathogenesis of inflammatory bowel disease (IBD). To study the role of gut microbiota in intestinal inflammation, the microbiome of control mice (C57BL6) given a gluten-containing standard diet versus C57BL6 mice given the gluten-free (GF) feed (n=10 in each group) was examined. All mice received the 3% DSS for 5 days. Throughout the study, feces were collected and processed for DNA extraction and MiSeq Illumina sequencing of V4 region of bacterial 16S rRNA gene. Alpha and beta diversities and compositional differences at phylum and genus levels were determined in intestinal microbiota. The mice receiving the GF diet showed a significantly increased abundance of Firmicutes and a decrease of Bacteroides and Lactobacillus at phylum level. Therefore, the gluten free diet led to reductions in beneficial gut bacteria populations.

However, the molecular mechanisms by which diabetes contributes to endothelial inflammation remain to be established. Using In-vitro cultured Human cells and Hsp60 specific ELISA assays, we show that Hsp60 is not only induced in Human monocyte cells under hyperglycaemic conditions but that the Hsp60 is also secreted from these cells. Furthermore, we also demonstrate that the Hsp60 secreted from these monocyte cells is also able to activate Toll-like receptor-4 (TLR4) from Human endothelial cells. This suggests that a potential link may exist between the hyperglycaemia-induced expression of Hsp60 in monocyte cells and vascular inflammation. Circulating levels of Hsp60 due to mitochondrial stress in diabetes patients could, therefore, be an important modulator of inflammation in endothelial cells and thus contribute to the increased incidences of atherosclerosis in diabetes mellitus. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mitochondria" title="mitochondria">mitochondria</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsp60" title=" Hsp60"> Hsp60</a>, <a href="https://publications.waset.org/abstracts/search?q=inflammation" title=" inflammation"> inflammation</a>, <a href="https://publications.waset.org/abstracts/search?q=diabetes%20mellitus" title=" diabetes mellitus"> diabetes mellitus</a> </p> <a href="https://publications.waset.org/abstracts/107492/activation-of-tnf-a-from-human-endothelial-cells-by-exposure-of-the-mitochondrial-stress-protein-hsp60-secreted-from-thp-1-monocytes-to-high-glucose" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107492.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">181</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">7972</span> Antigen-Presenting Cell Characteristics of Human γδ T Lymphocytes in Chronic Myeloid Leukemia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Piamsiri%20Sawaisorn">Piamsiri Sawaisorn</a>, <a href="https://publications.waset.org/abstracts/search?q=Tienrat%20%20Tangchaikeeree"> Tienrat Tangchaikeeree</a>, <a href="https://publications.waset.org/abstracts/search?q=Waraporn%20Chan-On"> Waraporn Chan-On</a>, <a href="https://publications.waset.org/abstracts/search?q=Chaniya%20Leepiyasakulchai"> Chaniya Leepiyasakulchai</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachanee%20Udomsangpetch"> Rachanee Udomsangpetch</a>, <a href="https://publications.waset.org/abstracts/search?q=Suradej%20Hongeng"> Suradej Hongeng</a>, <a href="https://publications.waset.org/abstracts/search?q=Kulachart%20Jangpatarapongsa"> Kulachart Jangpatarapongsa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Human Vγ9Vδ2 T lymphocytes are regarded as promising effector cells for cancer immunotherapy since they have the ability to eliminate several tumor cells through non-peptide antigen recognition and non-major histocompatibility complex (MHC) restriction. An issue of recent interest is the capability to activate γδ T cells by use of a group of drugs, such as pamidronate, that cause accumulation of phosphoantigen which is recognized by γδ T cell receptors. Moreover, their antigen presenting cell-like phenotype and function have been confirmed in many clinical trials. In this study, Vγ9Vδ2 T cells derived from normal peripheral blood mononuclear cells were activated with pamidronate and the expanded Vγ9Vδ2 T cells can recognize and kill chronic myeloid leukemia (CML) cells treated with pamidronate through their cytotoxic activity. To support the strong role played by Vγ9Vδ2 T cells against cancer, we provide the evidence that Vγ9Vδ2 T cells activated with CML cell lysate antigen can efficiently express antigen presenting cell (APC) phenotype and function. In conclusion, pamidronate can be used in intentional activation of human Vγ9Vδ2 T cells and can increase the susceptibility of CML cells to cytotoxicity of Vγ9Vδ2 T cells. The activated Vγ9Vδ2 T cells by cancer cells lysate can show their APC characteristics, and so greatly increase the interest in exploring their therapeutic potential in hematologic malignancy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=%CE%B3%CE%B4%20T%20lymphocytes" title="γδ T lymphocytes">γδ T lymphocytes</a>, <a href="https://publications.waset.org/abstracts/search?q=antigen-presenting%20cells" title=" antigen-presenting cells"> antigen-presenting cells</a>, <a href="https://publications.waset.org/abstracts/search?q=chronic%20myeloid%20leukemia" title=" chronic myeloid leukemia"> chronic myeloid leukemia</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer" title=" cancer"> cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=immunotherapy" title=" immunotherapy"> immunotherapy</a> </p> <a href="https://publications.waset.org/abstracts/103440/antigen-presenting-cell-characteristics-of-human-ghd-t-lymphocytes-in-chronic-myeloid-leukemia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103440.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">186</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">7971</span> The Impact of Diesel Exhaust Particles on Tight Junction Proteins on Nose and Lung in a Mouse Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kim%20Byeong-Gon">Kim Byeong-Gon</a>, <a href="https://publications.waset.org/abstracts/search?q=Lee%20Pureun-Haneul"> Lee Pureun-Haneul</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Jisu"> Hong Jisu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jang%20An-Soo"> Jang An-Soo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Diesel exhaust particles (DEPs) lead to trigger airway hyperresponsiveness (AHR) and airway dysfunction or inflammation in respiratory systems. Whether tight junction protein changes can contribute to development or exacerbations of airway diseases remain to be clarified. Objective: The aim of this study was to observe the effect of DEP on tight junction proteins in one airway both nose and lung in a mouse model. Methods: Mice were treated with saline (Sham) and exposed to 100 μg/m³ DEPs 1 hour a day for 5 days a week for 4 weeks and 8 weeks in a closed-system chamber attached to a ultrasonic nebulizer. Airway hyperresponsiveness (AHR) was measured and bronchoalveolar lavage (BAL) fluid, nasal lavage (NAL) fluid, lung and nasal tissue was collected. The effects of DEP on tight junction proteins were estimated using western blot, immunohistochemical in lung and nasal tissue. Results: Airway hyperresponsiveness and number of inflammatory cells were higher in DEP exposure group than in control group, and were higher in 4 and 8 weeks model than in control group. The expression of tight junction proteins CLND4, -5, and -17 in both lung and nasal tissue were significantly increased in DEP exposure group than in the control group. Conclusion: These results suggesting that CLDN4, -5 and -17 may be involved in the airway both nose and lung, suggesting that air pollutants cause to disruption of epithelial and endothelial cell barriers.
