Neuronal regulation of longevity by staying cool

Neuronal regulation of longevity by staying cool.

Aging is fundamental to life and reflects functional declines in different tissues at the organismal level. As a systematic process, aging can be influenced by the interplay between genetic and environmental factors, and the nervous system plays a crucial role in this regulation. Environmental inputs can be sensed by the nervous system, which consequently triggers signaling outputs toward perip...

Staying Cool when Things Get Hot: Emotion Regulation Modulates Neural Mechanisms of Memory Encoding

During times of emotional stress, individuals often engage in emotion regulation to reduce the experiential and physiological impact of negative emotions. Interestingly, emotion regulation strategies also influence memory encoding of the event. Cognitive reappraisal is associated with enhanced memory while expressive suppression is associated with impaired explicit memory of the emotional event...

Staying Cool Across the First Year of Middle School

As students transition into middle school they must successfully negotiate a new, larger peer context to attain or maintain high social standing. The goal of this study was to examine the extent to which the maintenance, attainment, and loss of a cool status over the course of the sixth grade is associated with student and classroom levels of physical, verbal, and relational aggression. To addr...

Inhibition of neuronal autophagy mediates longevity

Regulation of longevity and stress resistance by Sch9 in yeast.

The protein kinase Akt/protein kinase B (PKB) is implicated in insulin signaling in mammals and functions in a pathway that regulates longevity and stress resistance in Caenorhabditis elegans. We screened for long-lived mutants in nondividing yeast Saccharomyces cerevisiae and identified mutations in adenylate cyclase and SCH9, which is homologous to Akt/PKB, that increase resistance to oxidant...
