Research ArticleOpen accessIn the abstractThe Hypoxia-Inducible Factor-1α Signaling Pathway and its Relation to Cancer and ImmunologyBruno R.B. Pires, Andre L. Mencalha, Gerson M. Ferreira et al.Hypoxia-Inducible Factor 1 (HIF-1) is a transcription factor that is present in all metazoans from early embryonic development throughout adult life. It plays a major roles in the different stress responses that are triggered by low Oxygen (O2) levels and its expression is associated with cell survival. HIF-1 is a heterodimer protein that comprises the subunits HIF-1α and HIF-1β. The … …American Journal of Immunology, Vol. 10, Issue 4 · 17 Jan 2015 · 8,485 accessesView PDFCite

Research ArticleOpen accessIn the abstractASCORBIC ACID FOLIIAR SPRAY COUNTERACTING EFFECT OF SALINITY ON GROWTH, NUTRIENTS CONCENTRATIONS, PHOTOSYNTHESIS, ANTIOXIDANT ACTIVITIES AND LIPID PEROXIDATION OF BEAN (PHASEULUS VULGARIS L.) CULTIVARSZeinab A. Salama, El-Zanaty A.A. Abou El-Nour, Mohamed M. El Fouly, Alaa A. GaafarA water culture experiment was carried out in the Department of Fertilization Technology at National Research Centre, Cairo, Egypt, to investigate the effect of Ascorbic Acid (AsA) foliar application and salinity stress (100 ppm and 100 mmoL NaCl) on growth, nutrients concentration and some biochemical parameters of two kidney bean (Phaseulus Vulgaris L.) cultivars. Salinity caused significant reduction in growth … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 16 May 2014 · 7,906 accessesView PDFCite
Research ArticleOpen accessIn the abstractNEURO FUZZY BASED PERFORMANCE ANALYSIS OF MULTIBAND ULTRA WIDE BAND ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING SYSTEMG. Joselin Retna Kumar, K. S. ShajiThis study proposes an efficient channel-estimation scheme for Multiband (MB) Orthogonal Frequency Division Multiplexing (OFDM)-based Ultra Wide Band (UWB) communication systems. One of the challenges in wireless system is the frequency selective fading caused due to multipath channel between the transmitter and receiver. The signal bandwidth in broad band cellular wireless systems typically exceeds the coherence bandwidth of the multipath … …Journal of Computer Science, Vol. 10, Issue 8 · 5 Mar 2014 · 6,624 accessesView PDFCite
Research ArticleOpen accessIn the abstractRECONFIGURING EVOLVED CIRCUITS USING CONTROLLER: A REAL TIME APPROACHB. Hari Krishna, S. RaviFPGA is a device that contains a matrix of reconfigurable gate arrays that can implement different complex functions and also vary structurally. In this study, a novel method of reconfigurable circuit switching action is done with the help of a controller. BPSK Modulation application is chosen to demonstrate the reconfigurable action. When an event occurs the context/core switching is done … …Journal of Computer Science, Vol. 10, Issue 3 · 2 Dec 2013 · 6,378 accessesView PDFCite
Research ArticleOpen accessIn the abstractResearch Proposal: An Intrusion Detection System Alert Reduction and Assessment Framework Based on Data MiningKarim Al-Saedi, Selvakumar Manickam, Sureswaran Ramadass et al.The Intrusion Detection System (IDS) generates huge amounts of alerts that are mostly false positives. The abundance of false positive alerts makes it difficult for the security analyst to identify successful attacks and to take remedial actions. Such alerts to have not been classified in accordance with their degree of threats. They further need to be processed to ascertain the … …Journal of Computer Science, Vol. 9, Issue 4 · 8 May 2013 · 7,712 accessesView PDFCite
Research ArticleOpen accessIn the abstractFluctuation of Brain Tissue Oxygen Partial Pressure: A Biochemical Landmark in the Arctic Ground Squirrel's Spontaneous ArousalYi Long Ma, Shu Fen Wu, Lawrence K. DuffyHibernation in the Arctic ground Squirrel (AGS) is a regulated, adaptive response to arctic environmental conditions. Problem statement: Regional brain Blood Flow (rCBF) has been observed to increase dramatically during arousal in hibernators. However, the real time dynamic change in PtO2 during arousal has not been studied, we hypothesized that PtO2 is Interdependent of Tbrain and a key component in … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 4 · 1 Feb 2012 · 7,605 accessesView PDFCite
EditorialOpen accessIn the abstractChasing the Fat Demon: Fat Chance, Buddy?David L. Katz, Joachim Storsberg, Christian SchmidtScience is an interesting profession. At times, one could get caught up in his or her own world of thoughts, perception, far away from reality, sometimes referred to as the proverbial ivory tower (Lederberg, 1972). Science for the sake of science is, per se, not without merit, with our fragmented understanding of a given issue providing ample justification for experimentation … …American Journal of Immunology, Vol. 13, Issue 2 · 29 May 2017 · 8,137 accessesView PDFCite
Research ArticleOpen accessIn the abstractMelanoma-Associated Suppression of the Dendritic Cell Lines DC2.4 and JawsiiKristian Michael Hargadon, Yonathan Tarekegne Ararso, Osric Anthony Forrest, Chad Mason HarteDendritic cells function as potent regulators of both innate and adaptive immunity to tumors and the regulatory activities of these cells are tightly linked to their maturation and activation status. Despite the critical role played by dendritic cells in the induction of anti-tumor immune responses, the number of dendritic cells that can be isolated from experimental animals is limiting and … …American Journal of Immunology, Vol. 8, Issue 4 · 3 Nov 2012 · 9,567 accessesView PDFCite
