Photoperiodic regulation of behavioral responsiveness to proinflammatory cytokines

The effect of proinflammatory cytokines in Cognitive Behavioral Therapy

Major depressive disorder (MDD) is a debilitating disorder and its pathophysiology is associated with deregulation of the immune system. We investigated the changes in circulating levels of proinflammatory cytokines (specifically IL-6 and TNF-α) measured by the ELISA kit in two psychotherapeutic interventions for MDD: Narrative Cognitive Therapy (NCT) and Cognitive Behavioral Therapy (CBT). Thi...

Photoperiodic regulation

Adult male wild rabbits were exposed to artificial daylengths of 8L:16D, 13L:1 1D or 20L:4D after being taken from the wild during September, when testicular size was minimal. In all groups the testes grew and those in 20L:4D grew more quickly than did those in 8L:16D or 13L:11D. Rabbits kept in the 3 daylength treatments for the whole study maintained enlarged testes after the initial growth p...

Regulation of Nitric Oxide Synthesis by Proinflammatory Cytokines

We have examined cytokine regulation of nitric oxide synthase (NOS) in human umbilical vein endothelial cells (HUVEC). 24-h treatment with IFN-'y (200 U/ml) plus TNF (200 U/ml) or IL-1,8 (5 U /ml) increased NOS activity in HUVEC lysates, measured as conversion of I '4CIL-arginine to [ '4Cj L-citrulline. Essentially, all NOS activity in these cells was calcium dependent and membrane associated. ...

Proinflammatory Cytokines in Peritonitis

RATIONALE We performed this study with the purpose of revealing different aspects of the systemic inflammatory response syndrome in peritonitis. OBJECTIVES The aim of the presentation was to make a research on some of the immune response mediators in secondary peritonitis and to observe their capacity to anticipate the evolution towards septic complications. METHODS AND RESULTS We have unde...
