Hypertension and aging have similar effects on the structure and function of blood vessels and the heart. Both commonly result in decreased vascular compliance, endothelial dysfunction, and left ventricular (LV) hypertrophy and stiffness. Moreover, the risk of cardiovascular disease, including hypertension, increases exponentially with age in those 40 years of age. Therefore, one might surmise ...
Natural killer (NK) cells are a population of cytotoxic innate lymphocytes that evolved prior to their adaptive counterparts and constitute one of the first lines of defense against infected or mutated cells. NK cells are rapidly activated, expressing an array of germ-line encoded receptors that allow them to scan for protein irregularities on cells and kill those deemed "altered-self." NK cell...
Beam Induced Fluorescence Monitor Due to the high beam power expected for FAIR, novel methods for non-intersecting beam diagnostics for the High Energy Beam Transport Lines must be considered. We investigate the detection of fluorescence photons from the excited states of the residual gas N2 with a Beam Induced Fluorescence (BIF) Monitor [1]. This method was successfully applied for high curren...
The production of hydrogen peroxide (H2 O2 ) drives tumourigenesis in ulcerative colitis (UC). Recently, we showed that H2 O2 activates DNA damage checkpoints in human colonic epithelial cells (HCEC) through c-Jun N-terminal Kinases (JNK) that induces p21(WAF1) . Moreover, caspases circumvented the G1/S and intra-S checkpoints, and cells accumulated in G2/M. The latter observation raised the qu...
