Apoptosis or programmed cell death is a gene regulated phenomenon which is important in both physiological and pathological conditions. It is characterized by distinct morphological features including chromatin condensation, cell and nuclear shrinkage, membrane blebbing and oligonucleosomal DNA fragmentation. Although, two major apoptotic pathways including 1) the death receptor (extrinsic) and...

the features of helicobacter pylori adhesins, their interactions with their host counterparts, regulated and selective gene expressions are amongst the many clever strategies this microorganism undertakes to survive the otherwise sterile gastric milieu. the ingenious crafting of these interactions and the respective host reactions govern, in part, an array of consequences ranging from asymptoma...

several studies point to an important function of cyclooxygenase (cox) and prostaglandin signaling in models of synaptic plasticity which is associated with n-methyl-d-aspartate receptors (nmdars). cyclooxygenase gene is suggested to be an immediate early gene that is tightly regulated in neurons by nmda dependent synaptic activity. nonsteroid antiinflammatory drugs (nsaids) exert their antiinf...

background: the effects of electromagnetic field (emf) on reproductive system have been of critical concern for a long time. it has been shown that the emf can adversely affect testicular cells and tissue and decrease male fertility. the most important determinants of male fertility are sperm development and motility, which are affected by changes in several factors including lipocalin 2 protei...
