“Many neurocognitive models of anxiety emphasize the importance of a hyper-responsive threat-detection system centered on the amygdala, with recent accounts incorporating a role for prefrontal mechanisms in regulating attention to threat. Here we investigated whether trait anxiety is associated with a much broader dysregulation of attentional control. Volunteers performed a response-conflict task under conditions that posed high or low demands on attention. High trait-anxious individuals showed reduced prefrontal activity and slower target identification in response to processing competition when the task did not fully occupy attentional resources.

The relationship between trait anxiety and prefrontal recruitment remained after controlling for state anxiety. These findings indicate that trait anxiety is linked to impoverished recruitment of prefrontal attentional control mechanisms to inhibit distractor processing even when threat-related stimuli are absent. Notably, this deficit was observed when ongoing task-related demands on attention were low, potentially explaining the day-to-day difficulties in concentration that are associated with clinical anxiety.”
“Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by progressive loss of motor neurons. To analyze the

progressive motor deficits during Blasticidin S datasheet the course of this disease, we investigated fatigability and ability of recovery of spinal motor neurons by testing monosynaptic reflex transmission with increasing stimulus frequencies in the lumbar spinal cord of the SOD1(G93A) mouse model for ALS in a comparison with wild-type (WT) mice. Monosynaptic reflexes in WT and SOD1(G93A) mice without behavioral Dinaciclib purchase deficits showed no difference with respect to their resistance to increasing stimulus frequencies. During the progression of motor deficits in SOD1(G93A) mice, the vulnerability of monosynaptic reflexes to higher frequencies-increased, the required time for reflex recovery was extended, and recovery was often incomplete. Fatigability and demand for recovery of spinal motor neurons in SOD1(G93A) mice rose with increasing motor deficits. This supports the assumption that impairment of the energy supply may contribute to the pathogenesis of ALS. Muscle Nerve 43: 230-236, 2011″
“In order to determine the prevalence of methicillin (meticillin)-resistant Staphylococcus aureus (MRSA) colonization among adults in community settings in Taiwan and identify its risk factors, we conducted the present study. For a 3-month period, we enrolled all adults who attended mandatory health examinations at three medical centers and signed the informed consent. Nasal swabs were taken for the isolation of S. aureus.
