Research ArticleOpen accessIn the abstractAverage Mutual Information Analysis of Multiple Input and Multiple Output System with Multihop Relaying in Wireless Communication SystemC. Poongodi, A. ShanmugamProblem statement: Multiple Input and Multiple Output (MIMO) system with Multihop relaying techhnique is significant and active areas of wireless communication. In a rich scattering environment MIMO antenna system provides better channel capacity and data rates than single antenna systems. To provide high throughput, reliable transmission and broad coverage, wireless relaying techniques are essential in a variety of applications. In … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 25 Aug 2012 · 7,551 accessesView PDFCite
Research ArticleOpen accessIn the abstractCell-Based Therapies in the Prevention of Solid Organ Transplant RejectionAdrian E. Morelli, Sherrie J. DivitoProblem statement: Organ transplantation is a life-saving and increasingly common procedure, as it often serves as the only treatment available for end-stage organ disease. Although the constant development of new and more effective immunosuppressive drugs has revolutionized the prevention and treatment of acute graft rejection, these drugs have significant toxicity, greatly increase patient susceptibility to neoplasms and infection and exert … …American Journal of Immunology, Vol. 8, Issue 2 · 26 Jul 2012 · 7,416 accessesView PDFCite
Research ArticleOpen accessIn the abstractHistone Tail Modifications of H3 and H4 during the Physarum polycephalum Cell CycleMarie-Claire Arnaud, Christophe ThirietProblem statement: Histone modifications are required for chromatin activities and are believed to form an epigenetic code. However, the inheritance of the histone post-translational modifications remains unclear. Approach and Results: The aim of this study was to evaluate the histone modifications throughout the cell cycle and to determine whether the histone marks are transferred to daughter cells. Using the naturally … …OnLine Journal of Biological Sciences, Vol. 12, Issue 2 · 29 May 2012 · 7,580 accessesView PDFCite
Research ArticleOpen accessIn the abstractStructural and Evolutionary Analysis of PARPs in D. discoideumA. Mehadvi Kawal, Hina A. Mir, Chethan Kumar Ramniklal et al.Problem statement: Dictyostelium discoideum, a unicellular eukaryote, exhibits multicellularity upon nutrient starvation, making it a better model for developmental studies and for the study of various signal transduction pathways. The most felicitous point of interest is that many of its genes show high degree of similarity to vertebrate genes. Poly (ADP-ribose) polymerase (PARP), a ubiquitous and abundant nuclear protein, has … …American Journal of Infectious Diseases, Vol. 7, Issue 3 · 3 Nov 2011 · 7,852 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Reduced Finite Element Model for Analyzing the Transverse Shear Stiffness of Truss-Like Core Sandwich BeamSuphattharachai Chomphan, Manit LeekitwattanaProblem statement: In structural analysis using finite element software, a number of finite element equations affect the speed of calculation time. A reduced finite element model should be used for analyzing structural responses to reduce the calculation time. Approach: This study presents the analysis of transverse shear stiffness of truss-like core sandwich beam using the reduced finite element model based … …Journal of Computer Science, Vol. 7, Issue 10 · 4 Aug 2011 · 6,589 accessesView PDFCite
Research ArticleOpen accessIn the abstractEntropyomics as the Blueprint of the Logic of Normal Cell Division and MalignancyKambiz AfrasiabiProblem statement: In this article I propose a blueprint based on one of the most fundamental laws governing the known universe, namely the second law of thermodynamics and I present support for its central role in initiation of mitosis and relationship of the other sub cellular compartments and their organization. Approach: Life is considered to be the most sophisticated antientropy … …OnLine Journal of Biological Sciences, Vol. 11, Issue 1 · 6 Jul 2011 · 10,377 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn Vitro and In Vivo Anticancer Activity of Bacoside A from Whole Plant of Bacopa Monnieiri (Linn)N. S. Prakash, R. Sundaram, S. K. MitraProblem statement: Natural products have long been a fertile source of cure for cancer, which is projected to become the major cause of death in this century. Major classes of anticancer compounds include alkaloids, terpenoids, flavonoids and lignans. We have chosen terpenoids (bacosides) because terpenoids like taxol are currently being used in cancer chemotherapy. The anticancer activity of Bacoside A … …American Journal of Pharmacology and Toxicology, Vol. 6, Issue 1 · 7 Jun 2011 · 9,663 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling Growth of Microalgae Dunaliella Salina under Different Nutritional ConditionsSergio Santos Jesus, Rubens Maciel FilhoProblem statement: The aim of this study was to find the empirical model that describes the growth kinetics of Dunaliella salina, with low production cost and to estimate parameters of this model. Approach: In this study the strain of D. salina UTEX 200 was cultivated in seawater (0.5 M NaCl) at room temperature with agitation of 150 rpm and luminous … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 4 · 31 Dec 2010 · 9,014 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntibiotic Susceptibility and Immunomodulatory Potential of Chosen Bacterial PathogensM. Sujatha, P. Dhasarathan, B. KarthickProblem statement: Antibiotic susceptibility is still the best way for bacterial pathogen escape mechanism against immunity. Approach: In the present investigation, bacterial pathogens like Staphylococcus aureus, Escherichia coli, Aeromonas hydrophila, Klebsiella and Pseudomonas aeruginosa were used to screen antibiotic susceptibility and immunomodulatory potential. Results: All the test pathogens were sensitive to all the test antibiotics 11±2 mm) except penicillin. The … …American Journal of Immunology, Vol. 6, Issue 2 · 30 Jun 2010 · 7,829 accessesView PDFCite
Research ArticleOpen accessIn the abstractFoxp3-Mediated Immunity of Human Pancreatic Cancer Cell Line PANC-1Renxi Wang, Gencheng Han, Jianan Wang et al.Problem statement: More and more evidences have shown that human cancer cells can express Foxp3, the regulatory T cell-associated transcription factor. The role of Foxp3 in human cancer cells is still unclear. We detected Foxp3 expression in human pancreatic cancer cell line PANC-1. SiRNA assays showed that Foxp3 expression suppressed the expression of TGF-β and IL-10 which could induce immune … …American Journal of Immunology, Vol. 5, Issue 4 · 11 Jan 2010 · 7,363 accessesView PDFCite
