Purpose: We determined the prevalence of risk factors for the development of acute respiratory distress syndrome (ARDS), outcomes of critical illness, and the impact of highly active antiretroviral therapy in HIV-1-infected patients. We hypothesized that in an urban county hospital, HIV-1-infected patients with ARDS would have a higher mortality than their HIV-1-uninfected counterparts. Materials...
Excessive activation of NMDA glutamate receptors contributes to neuronal death after stroke. In this issue, Tu et al. (2010) demonstrate that ischemic injury promotes the association of death-associated protein kinase 1 with the NMDA receptor, thereby potentiating its activity, and show that disrupting this association reduces damage to the brain.
Epidemiological evidence suggests a link between chronic oxygen starvation and fat accumulation/obesity, however the underlying mechanism remains unclear. Using Caenorhabditis elegans we found extended oxygen deprivation resulted in activation of SBP-1, the worm homologue of SREBP1, a transcription factor important in maintaining lipid homeostasis. SBP-1 knockdown prevented hypoxia-induced fat accumulation...
