BACKGROUND The high morbidity and socio-economic loss associated with the recent massive global outbreak of Chikungunya virus (CHIKV) emphasize the need to understand the biology of the virus for developing effective antiviral therapies. METHODS AND FINDINGS In this study, an attempt was made to understand the molecular mechanism involved in Heat shock(More)
Chikungunya virus (CHIKV) infection is one of the most challenging human Arboviral infections with global significance and without any specific antiviral. In this investigation, 1-[(2-methylbenzimidazol-1-yl) methyl]-2-oxo-indolin-3-ylidene] amino] thiourea (MBZM-N-IBT) was synthesised as a molecular hybrid of 2-methyl benzimidazole and(More)
The recent epidemics of Chikungunya viruses (CHIKV) with unprecedented magnitude and unusual clinical severity have raised a great public health concern worldwide, especially due to unavailability of vaccine or specific therapy. This emphasizes the need to understand the biological processes of this virus in details. Although CHIKV associated research has(More)
BACKGROUND The recent re-emergence of Chikungunya virus (CHIKV) in India after 32 years and its worldwide epidemics with unprecedented magnitude raised a great public health concern. METHODS AND FINDINGS In this study, a biological comparison was carried out between a novel 2006 Indian CHIKV outbreak strain, DRDE-06 and the prototype strain S-27 in(More)
Sperm cells exhibit extremely high sensitivity in response to slight changes in temperature, osmotic pressure and/or presence of various chemical stimuli. In most cases throughout the evolution, these physico-chemical stimuli trigger Ca (2+)-signaling and subsequently alter structure, cellular function, motility and survival of the sperm cells. Few reports(More)
The evolutionary conserved, less-polymorphic, nonclassical major histocompatibility complex (MHC) class I molecules: Qa-1 and its human homologue human leukocyte antigen-E (HLA-E) along with HLA-F, G and H cross-talk with the T-cell receptors and also interact with natural killer T-cells and other lymphocytes. Moreover, these nonclassical MHC molecules are(More)
Chikungunya virus (CHIKV) infection has re-emerged as a major public health concern due to its recent worldwide epidemics and lack of control measures. Although CHIKV is known to infect macrophages, regulation of CHIKV replication, apoptosis and immune responses towards macrophages are not well understood. Accordingly, the Raw264.7 cells, a mouse macrophage(More)
The Scalable Coherent Interface (SCI) is a recently developed IEEE standard that deenes a scalable high performance multiprocessor network. The SCI concept ooers enormous potential improvement in both performance and life-cycle-cost with regard to the future of multiproces-sor computing. Unfortunately, the high potential ooered by SCI, as it is currently(More)
