Voltage-gated calcium channels are key regulators of neuronal excitability. Several studies indicate that intoxicating concentrations of ethanol inhibit L-type, N-type and possibly T-type channels. The effects of ethanol on other channel subtypes are not yet clear. Chronic exposure to ethanol is associated with increases in functional L-type channels and(More)
Rat extensor digitorum longus muscles were overloaded by stretch after removal of the synergist tibialis anterior muscle to determine the relationship between capillary growth, muscle blood flow, and presence of growth factors. After 2 wk, sarcomere length increased from 2.4 to 2.9 micrometers. Capillary-to-fiber ratio, estimated from alkaline(More)
OBJECTIVES In this study we evaluate gender differences in affective adaptation and health perception in patients 6 months after stent implantation. BACKGROUND Assessment of gender-specific behavioral strategies to cope with serious cardiac disease conditions has not been given much attention until now. Preliminary data suggest greater impairments in(More)
The s/s-genotype of the 5-HTTLPR polymorphism and the personality trait of neuroticism have both been associated with experiences of negative affect, anxiety and mood disorders, as well as an emotional processing bias towards negative facial emotions. On a neural level, this bias can be characterized by altered amygdala and fusiform gyrus (FFG) activity(More)
Chronic exposure to ethanol increases the number of functional L-type voltage-gated calcium channels in neural cells. In PC12 cells, this adaptive response is mediated by protein kinase C delta (PKCdelta), but the mechanisms by which this occurs are not known. Since expression of several different calcium channel subunits can increase the abundance of(More)
BACKGROUND Monocyte activation induces different procoagulant and proadhesive inflammatory responses and thus may play a role in thrombotic complications after coronary interventions. Monocyte-platelet interaction may trigger these effects inducing monocyte activation. AIMS To characterize the effect of antiplatelet vs anticoagulation therapy on(More)
Background.  Although acquired immune deficiency syndrome-associated morbidity has diminished due to excellent viral control, multimorbidity may be increasing among human immunodeficiency virus (HIV)-infected persons compared with the general population. Methods.  We assessed the prevalence of comorbidities and multimorbidity in participants of the Swiss(More)
