Chronic unpredictable stress inhibits nociception in male rats [PDF]
, 2004 Chronic stress elicits remarkable alterations to the structure and function of several areas of the central nervous system. Nociception is known to be affected by chronic stress and age, although the observations are contradictory. Herein we report that

The Anatomical Record, EarlyView.The largest silesaurid known from South America is described here, demonstrating that silesaurids reached large body sizes in southwestern Gondwana. This discovery further underscores the widespread geographic distribution and temporal persistence of large silesaurids across Pangea, despite faunal turnovers and environmental events such as the Carnian ...
