Research ArticleOpen accessEvery word in the titleOptoelectronic Characterisation of Silicon and CIGS Photovoltaic Solar CellsRicardo A. Marques Lameirinhas, Afonso Ravasco, Catarina Pinho Correia Valério Bernardo, João Paulo N. TorresThroughout these years, many materials have been subjected to tests and experiments, creating several photovoltaic technologies and generations. In this article, some of these generations are compared, namely silicon and Copper Indium Gallium di-Selenide (CIGS), in order to characterize both materials in an optoelectronic way. Using a 2D solar cell PIN model using COMSOL software, both materials are tested, obtaining … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 1 · 30 Jan 2024 · 4,984 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleTaxifolin Potently Diminishes Levels of Reactive Oxygen Species in Living Cells Possibly by Scavenging Peroxyl RadicalsSatoru Sakuma, Yui Kishiwaki, Mayu Matsumura et al.Taxifolin, a naturally occurring dihydroflavonol, has been reported to possess antioxidant activity, whereas there is little information regarding its antioxidant potency as a flavonoid. In the present study, the antioxidant efficacy of taxifolin in living cells was compared to that of catechin, a potent radical scavenger, by using flow cytometry with the redox-sensitive fluorescent dye, 2′,7′-dichlorodihydrofluorescein diacetate. Further, diminishing efficacy … …American Journal of Pharmacology and Toxicology, Vol. 13, Issue 1 · 18 Oct 2018 · 8,058 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleMechanically Stimulated Osteoblast Cells GrowthRaffaella Aversa, Antonio Apicella, Francesco Tamburrino, Florian Ion Tiberiu PetrescuThe bones need to be built and then permanently restored to keep them functioning properly. Considering the multiple bone functions, their vitality is essential both to maintain the body and move it and to maintain its health and vigor. When most bones begin to age and have no vital function, the man also begins to age, lose water, minerals, electrolytes, … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 19 Jun 2018 · 7,888 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleThe Action of Bovine Cartilage on Tumor Cells In Vitro And In VivoArax Tanelian, Alexander M. AbdelnoorIn an earlier study we had investigated the effect of Bovine Cartilage (BC) on mouse melanoma cells. In pursuant to this study BC anti-tumor activity in vitro against several human tumor cell lines was evaluated, mechanism by which BC induces tumor cell death was studied and its immunogenicity was assessed. Five mice received Intraperitoneal (IP) injection of BC once every … …American Journal of Immunology, Vol. 14, Issue 1 · 23 Jan 2018 · 9,667 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleSequence Analysis of Scaffold/Matrix Attachment Regions (S/MARs) From Human Embryonic Kidney and Chinese Hamster Ovary CellsNur Shazwani Mohd Pilus, Azrin Ahmad, Nurul Yuziana Mohd YusofBinding of intergenic Scaffold/Matrix Attachment Regions (S/MARs) to nuclear matrix proteins is believed to poise adjacent genes for transcription by forming chromatin loops. Vector constructs containing Scaffold/Matrix Attachment Regions (S/MAR) flanking the gene of interest, therefore, are able to enhance recombinant protein expression in mammalian cells. We compared two methods that are based on buffers containing 2M NaCl and Lithium-3,5-diidosalicylate … …OnLine Journal of Biological Sciences, Vol. 18, Issue 4 · 8 Oct 2018 · 7,637 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleDifferential Gene Expression of Peroxide Resistant Protein (AhpC) in Planktonic and Biofilm State of Uropathogenic Escherichia coli CellsOmar Sadik Shalal, Ani-Simona SevastreThe gastrointestinal tract seems to be the primary reservoir of Uropathogenic Escherichia coli (UPEC) in humans. UPEC strains harbor the Urinary Tract (UT) and cause Urinary Tract Infections (UTI) which might represent a serious threat to human life. To counteract with the damage caused by the Reactive Oxygen Species (ROS), bacterial strains produce various enzymes and proteins like Alkyl hydroperoxide … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 3 · 13 Oct 2023 · 5,328 accessesView PDF Cite
