6S RNA function enhances long-term cell survival.
6S RNA was identified in Escherichia coli >30 years ago, but the physiological role of this RNA has remained elusive. Here, we demonstrate that 6S RNA-deficient cells are at a disadvantage for survival in stationary phase, a time when 6S RNA regulates transcription. Growth defects were most apparent as a decrease in the competitive fitness of cells lacking 6S RNA. To decipher the molecular mech...
متن کاملBlock of 5-HT2 Receptors Enhances Hippocampal Long-Term Potentiation
The effect of endogenous serotonin on long-term potentiation (LTP) in region CAI was studied by blocking 5-HT2 receptors with ketanserin in rat hippocampal slices. Such a block significantly en-hanced long-term potentiation of the CAI population spike induced by high frequency stimulation of the schaffer collateral/ commissural pathway. This implies that serotonin acts on 5-HT2 receptors in CAI...
متن کاملLight Enhances Survival of Dinoroseobacter shibae during Long-Term Starvation
Aerobic anoxygenic phototrophs (AAPs) as being photoheterotrophs require organic substrates for growth and use light as a supplementary energy source under oxic conditions. We hypothesized that AAPs benefit from light particularly under carbon and electron donor limitation. The effect of light was determined in long-term starvation experiments with Dinoroseobacter shibae DFL 12(T) in both compl...
متن کاملPredictors of Long-Term Survival after Cardiopulmonary Resuscitation
Abstract Introduction: Survival after cardiac arrest is one of the most important issues related to the safety and quality of patient care, and unexpected events such as failure to follow guidelines can endanger the patient's safety. Objective: This study aimed to determine the long-term survival after cardiopulmonary resuscitation and its predictors in patients with cardiac arrest. Materi...
متن کاملEmbryonic Cardiomyocyte, but Not Autologous Stem Cell Transplantation, Restricts Infarct Expansion, Enhances Ventricular Function, and Improves Long-Term Survival
AIMS Controversy exists in regard to the beneficial effects of transplanting cardiac or somatic progenitor cells upon myocardial injury. We have therefore investigated the functional short- and long-term consequences after intramyocardial transplantation of these cell types in a murine lesion model. METHODS AND RESULTS Myocardial infarction (MI) was induced in mice (n = 75), followed by the i...
