In order to know the mode of action of norepinephrine in enhanced utilization of plasma free fatty acids (FFA) in cold acclimation, albumin-bound 14C-palmitate was infused intravenously at a constant rate into cold- and warm-acclimated rats under pentobarbital anesthesia with and without norepinephrine infusion. Rectal temperature, CO2 output and plasma FFA, from which the rates of FFA uptake a...
Mechanisms underlying cold-induced immunosuppression remain unclear. Here we found that cold exposure leads to transient receptor potential melastatin 8 (TRPM8)-dependent, renin-angiotensin-aldosterone system (RAAS)-mediated hypertension, which subsequently induces small molecule and fluid extravasation, increases plasma Ig levels, and elicits immunosuppression. An effect is similar to the clin...
High glucocorticoid concentrations are accompanied by metabolic side effects such as high plasma triglyceride (TG) concentrations. Liver, brown adipose tissue (BAT) and white adipose tissue are important regulators of plasma TG. Exposure to 4°C reduces plasma TG concentrations, and we therefore aimed to study the interaction between glucocorticoid excess and 24 hours of exposure to 4°C on lipid...
Molecular mechanisms underlying the cold-associated high cardiovascular risk remain unknown. Here, we show that the cold-triggered food-intake-independent lipolysis significantly increased plasma levels of small low-density lipoprotein (LDL) remnants, leading to accelerated development of atherosclerotic lesions in mice. In two genetic mouse knockout models (apolipoprotein E(-/-) [ApoE(-/-)] an...
OBJECTIVE It is a well documented fact that under stress conditions the hypothalamic-pituitary-adrenal axis (HPA) and the sympathetic nervous system (SNS) are stimulated. This results in a series of neural and endocrine adaptations known as the stress response. The current study assessed the effects of acute cold stress on adrenomedullin (ADM) levels in plasma and peripheral tissues (kidneys an...
In the last twenty years new antibacterial agents approved by the U.S. FDA decreased whereas in parallel the resistance situation of multi-resistant bacteria increased. Thus, community and nosocomial acquired infections of resistant bacteria led to a decrease in the efficacy of standard therapy, prolonging treatment time and increasing healthcare costs. Therefore, the aim of this work was to de...
Experiments were performed to investigate whether proteins other than fibrin are substrates for activated fibrin-stabilizing factor (FSF, blood coagulation Factor XIII, plasma transglutaminase) in clotting whole plasma. Three fluorescently labeled polypeptides were identified in serum prepared by clotting normal, but not FSF-deficient, plasma in the presence of the fluorescent amine, N-(5-amino...
The chemical composition of plasma membrane fractions isolated from orchard grass seedlings (Dactylis glomerata L.) was analyzed and compared with endomembranes. The plasma membrane is characterized by an enrichment of sterols and a lower degree of unsaturation of phospholipids. Steryl glycosides were found to be one of the lipid components of the plasma membrane, but steryl esters and galactol...
