Research ArticleOpen accessEvery word in the titleDesign of a Low Power and High Speed Comparator using MUX based Full Adder Cell for Mobile CommunicationsG. Ramana Murthy, Ajay Kumar Singh, P. Velraj Kumar, Tan Wee Xin WilsonThis paper presents an implementation of comparator (1-bit) circuit using a MUX-6T based adder cell. MUX-6T full adder cell is designed with a combination of multiplexing control input and Boolean identities. The proposed comparator design features higher computing speed and lower energy consumption due to the efficient MUX-6T adder cell. The design adopts multiplexing technique with control input to alleviate … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 16 Jan 2017 · 8,251 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleQuercetin Iron (III) Complex Enhances Radiation-Induced Cell Death in Human Erythroleukemic Cell Lines by Increasing the Generation of Intracellular ROSJiraporn Kantapan, Krai Daowtak, Kachaporn Gateprayoon et al.Quercetin iron (III) complex (IronQ) is a paramagnetic agent which exhibits several biological effects. Despite extensive studies about quercetin metal complex, the role of complexes to enhance the effect of radiation still remains unexplored. To this end, we determined whether and how IronQ sensitizes cancer cells to Ionizing Radiation (IR). Doxorubicin resistant leukemic cells (K562/Adr) and their parental cell lines … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 16 Jan 2017 · 8,064 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Serial Passaging on the Morphology and Biological Characteristics of Human Adipose Tissue-derived Stem CellsLenka Oravcova, Martin Bohac, Lubica Krajciova et al.Somatic stem cells posses an exclusive property of self regeneration and plasticity which makes them promising candidates for use in tissue engineering and regenerative medicine. In the case of stem cell therapy it is crucial to obtain them in sufficient amount. That's why they have to be cultured under in vitro conditions. Long term culture provides adequate number of cells, … …OnLine Journal of Biological Sciences, Vol. 16, Issue 4 · 17 Dec 2016 · 7,242 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluation of Mast Cell Distribution in Oral Lichen Planus and Lichenoid Lesions by Immunohistochemical and Histochemical AnalysisMahi Balci, Mustafa Emre ErcinThe histopathological assessment of Oral Lichen Planus (OLP) and oral lichenoid lesions is relatively subjective. The distinguishing criteria established by WHO effectively reproducible when all selection criteria were fulfilling but sometimes fail to provide a reliable diagnosis. The aim of the present study was to evaluate mast cell counts and their distribution among OLP and lichenoid lesions. The density and … …American Journal of Immunology, Vol. 12, Issue 4 · 11 Dec 2016 · 7,791 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePotential of HMEC-1 Line and HUVEC Primary Culture Cells to Study the Neonatal IgG Fc Receptor in vitroLuz Belinda Ortiz-Alegría, Irma Cañedo-Solares, Felipe Vadillo-Ortega et al.The neonatal IgG Fc receptor (FcRn) plays an important role in IgG homeostasis and immunity passive transfer. Fine points regarding these mechanisms, however, are still emerging. In order to obtain information about these phenomena, it is essential to have in vitro models of endothelium that express this receptor. In this study we chose two widely used models of human endothelial … …American Journal of Immunology, Vol. 12, Issue 1 · 21 Mar 2016 · 9,446 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCD2 Shown to Facilitate CD4+ Cell Differentiation during Visceral Leishmaniasis, a Receptor Based StudySukrat Sinha, Shanthy Sundaram, Sanjiva Bimal et al.This study addressed the role of CD2 on CD4+ T helper cells in relation to the TCRVα1 and CD70 in two groups of BALB/c mice viz control and infected (1×107 L. donovani promastigotes). The results showed with the downregulation of CD2 expression there is a pronounced decrease of TCRVα1 and CD70 on CD4+ cells in mice. An insight into the … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 4 · 28 Nov 2015 · 7,828 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePassage Effect on Aging of Human Umbilical Cord Derived Mesenchymal Stem CellDian Mediana, Isabella Kurnia Liem, Jeanne Adiwinata Pawitan, Noviyanti GoeiTo be used in regenerative medicine, cells should be checked for various conditions, including cell aging. This study aimed to learn senescent profile and its relation to cell viability, proliferation and cell size in various passages, which were done in α-MEM-10% PRP medium, until senescence-associated β-galactosidase (SA-β-Gal) positive cells were found. Stem cells were isolated from umbilical cord tissue by … …OnLine Journal of Biological Sciences, Vol. 15, Issue 3 · 31 Jul 2015 · 8,039 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Platelet Rich Plasma on Post Cryopreservation Viability, Morphology and Proliferation of Human Umbilical Cord Stem CellsNoviyanti Goei, Isabella Kurnia Liem, Jeanne Adiwinata Pawitan, Dian MedianaIn most cryopreservation medium, Fetal Bovine Serum (FBS) is used as supplement, while it is well known that FBS contains xenoproteins that can be incorporated into the cells and may be harmfull, as they can elicit immune response. Therefore, finding other xenofree materials as FBS alternative in cryopreservation medium is very important. Platelet Rich Plasma (PRP) is albumin rich and … …OnLine Journal of Biological Sciences, Vol. 15, Issue 2 · 4 Jun 2015 · 7,386 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Short Term in vitro Stress Hormone Exposure on Regulatory T Cell Number and Function in AsthmaKristina E. Rehm, Gailen D. Marshall, Jr.Asthma is characterized by alterations in the immune system, including regulatory T cells (Treg). Further alterations in Treg numbers and/or function caused by stress hormones may be a contributing factor in asthma pathogenesis. We compared Treg populations and the effects of Dexamethasone (DEX, a laboratory analog of cortisol) on Treg cell number and function in patients with asthma and a … …American Journal of Immunology, Vol. 11, Issue 1 · 24 Apr 2015 · 6,608 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleControl of Incoming H2/O2 Flows in a PEM Fuel CellDhia Mzoughi, Nabila Khili, Hatem Allagui, Abdelkader MamiIt has become crucial, with the dwindling of energy resources related to the depletion risk of fossil and fissile resources, to find energy alternatives which have the same properties as those of a hydrocarbon in terms of transport and storage.
