Repeated, but not acute, stress suppresses inflammatory plasma extravasation

Repeated, but not acute, stress suppresses inflammatory plasma extravasation.

Clinical findings suggest that inflammatory disease symptoms are aggravated by ongoing, repeated stress, but not by acute stress. We hypothesized that, compared with single acute stressors, chronic repeated stress may engage different physiological mechanisms that exert qualitatively different effects on the inflammatory response. Because inhibition of plasma extravasation, a critical component...

Repeated sampling but not sampling hour affects plasma carotenoid levels.

Carotenoid pigments have become a central subject of research on animal signaling systems during the past decade. Thus, measurement of plasma carotenoid levels is widespread in the literature. Many plasma biochemical parameters tend to vary with the hour of sampling, which may be an important source of sampling error. However, little is known about this kind of variation for circulating caroten...

Acute Airways Neutrophilia Cytokine Production but Does Not Affect Lipopolysaccharide-Induced Inflammatory Acrolein Inhalation Suppresses

Acute stress affects risk taking but not ambiguity aversion

Economic decisions are often made in stressful situations (e.g., at the trading floor), but the effects of stress on economic decision making have not been systematically investigated so far. The present study examines how acute stress influences economic decision making under uncertainty (risk and ambiguity) using financially incentivized lotteries. We varied the domain of decision making as w...

S100A12 Suppresses Pro-inflammatory, but Not Pro-Thrombotic Functions of Serum Amyloid A

S100A12 is elevated in the circulation in patients with chronic inflammatory diseases and recent studies indicate pleiotropic functions. Serum amyloid A induces monocyte cytokines and tissue factor. S100A12 did not stimulate IL-6, IL-8, IL-1β or TNF-α production by human peripheral blood mononuclear cells but low amounts consistently reduced cytokine mRNA and protein levels induced by serum amy...
