Research ArticleOpen accessEvery word in the titleMutations in Tumor suppressor TP53 Gene in Formalin- Fixed, Paraffin Embedded Tissues of Squamous Cell Carcinoma (SCC) of Lung CancerAbbas Mohammadi, Ali Vaziri Gohar, Mohamad Reza ShakibaieThe TP53 gene mutations have been extensively studied in lung cancer and have been used as a means to understand the origin(s) and mechanisms of these mutations in lung cancer development. TP53 gene mutations occur frequently in many human cancers. Analysis of TP53 gene mutations can also provide clues to the etiology of tumor formation. Formalin-fixed, paraffin embedded (FFPE) tissues … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 1 · 31 Mar 2008 · 8,000 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInvestigations on the Grasping Contact Analysis of Biological Tissues With Applications in Minimally Invasive SurgeryAli Bonakdar, Javad Dargahi, Rama BhatAnalytical and finite element methods are employed to determine the contact pressure on the surface of a tissue being grasped by an endoscopic grasper, in Minimally Invasive Surgery (MIS). Normally, an endoscopic grasper is corrugated (teeth-like) in order to grasp slippery tissues. It is highly important to avoid damage to the tissues while grasping and manipulation during endoscopic surgery. Therefore, … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 6,905 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleClassification of Squamous Cell Carcinoma Based On Color and Textural Features in Microscopic Images of Esophagus TissuesP. S. Hiremath, Y. Humnabad Iranna, Jagadeesh D. PujariThis paper presents a method for feature extraction using color and texture from microscopic images of esophagus tissues obtained from the abnormal regions of human esophagus detected through endoscopy. This method is used for classification of Squamous Cell Carcinoma (SCC) of esophagus, namely, poorly differentiated SCC, moderately differentiated SCC, and well differentiated SCC. Three different color spaces, namely, HSV, YCbCr, … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,874 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSex Dimorphism in the Fgf21 Gene Expression in Liver and Adipose Tissues is Dependent on the Metabolic ConditionNadezhda Bazhan, Tatiana Jakovleva, Natalia Balyibina et al.Fibroblast growth factor-21 (FGF21) beneficially affects carbohydrate and lipid metabolism. Previously, a sex-specific activation of Fgf21 expression was observed in humans and animals with metabolic diseases. It is unknown whether the sex differences in the Fgf21 expression are manifested in response to the natural physiological situations of fasting and refeeding. The aim of this work was to determine liver, White … …OnLine Journal of Biological Sciences, Vol. 19, Issue 1 · 29 Jan 2019 · 8,153 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIn Silico Analysis of Cellulose Synthase Gene (NcCesA1) in Developing Xylem Tissues of Neolamarckia CadambaTiong Shing Yiing, Ho Wei Seng, Pang Shek Ling, Ismail JusohThis study reported the isolation and in silico characterization of full-length cellulose synthase (CesA) cDNA from Neolamarckia cadamba, an important tropical plantation tree species. CesA is a member of processive glycosyltransferases that involved in cellulose biosynthesis of plants. CesA acts as a central catalyst in the generation of plant cell wall biomass or cellulose. It also plays an important role … …Current Research in Bioinformatics, Vol. 3, Issue 2 · 13 Jan 2015 · 7,990 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEFFECT OF COPPER SULPHATE AND COBALT CHLORIDE ON GROWTH OF THE IN VITRO CULTURE TISSUES FOR DATE PALM (PHOENIX DACTYLIFERA L.) CV. ASHGARAhmed Madi Waheed AL-MayahiThis study was carried out to investigate the effects of copper sulphate and cobalt chloride on propagation of date palm cv. Ashgar in vitro. The rate of callus proliferation was significantly higher in the medium supplemented with 2 µM copper sulphate and 2 µM cobalt chloride together (p<0.05). Addition of copper sulphate and Cobalt chloride to the medium was most … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 27 Nov 2013 · 8,456 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Gestation and Maternal Copper on the Fetal Fluids and Tissues Copper Concentrations in SheepAbd Elghany Hefnawy, Jorge Tortora-Perez, Saad Mohamed Shousha, Seham Youssef AbuKoraProblem statement: Samples of allantoic, amniotic fluid, fetal liver, kidney, maternal plasma and liver were collected from 30 ewes and classified into either early or late gestation and copper concentrations were measured. Approach: The Cu concentrations in the maternal plasma, allantoic, amniotic fluid, fetal liver and kidney increased significantly (p<0.01) during late gestation while maternal liver Cu decreased significantly (p<0.01). … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 2 · 20 Sep 2011 · 7,466 accessesView PDFCite
Research ArticleOpen accessIn the keywordsForest Fires and Resuspension of Radionuclides into the AtmosphereFernando P. Carvalho, Joao M. Oliveira, Margarida MaltaProblem statement: Forest fires are especially frequent around the Mediterranean Sea basin in the summer period and might be able to release naturally-occurring and man-made radionuclides from plant biomass and inject them into the atmosphere. The impact of this radioactivity on populations was not investigated before. Approach: Radionuclide analysis was performed in plants, in smoke from plant burning and in … …American Journal of Environmental Sciences, Vol. 8, Issue 1 · 14 Jan 2012 · 7,352 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSide Effects and Complications of Dental Materials on Oral CavityZahra Atai, Mohammad AtaiDevelopment of dental materials has had a great impact on the modern dentistry. The materials ranging from polymers to metals have different applications in dentistry.
