RATIONALE The behavioral effects of allopregnanolone (3alpha-hydroxy-5alpha-pregnan-20-one) in women are not known. OBJECTIVE Allopregnanolone, a neuroactive steroid secreted by the mammalian ovary, exerts its anesthetic, anxiolytic, and sedative/hypnotic effects through potentiation of GABAA receptors. The purpose of this study was to evaluate the(More)
That 3alpha-hydroxy-5alpha/beta-pregnane steroids (GABA steroids) have modulatory effects on the GABA-A receptor is well known. In behavioral studies in animals high exogenous dosages give concentrations not usually reached in the brain under physiological conditions. Animal and human studies show that GABA-A receptor-positive modulators like barbiturates,(More)
To explore how cardiac regeneration and cell turnover adapts to disease, different forms of stress were studied for their effects on the cardiac progenitor cell markers c-Kit and Isl1, the early cardiomyocyte marker Nkx2.5, and mast cells. Adult female rats were examined during pregnancy, after myocardial infarction and ischemia-reperfusion injury with/out(More)
OBJECTIVE To compare severity of negative mood and physical symptoms between women with different progesterone, allopregnanolone, and pregnanolone plasma concentrations during sequential Hormone Replacement Therapy (HRT) with vaginal progesterone suppositories. DESIGN A randomized, placebo-controlled, double-blind, crossover study. METHOD Postmenopausal(More)
The aim of this paper was to evaluate whether primary health care staff's referral of patients to perform an electronic screening and brief intervention (e-SBI) for alcohol use had a greater impact on change in alcohol consumption after 3 month, compared to patients who performed the test on their own initiative. Staff-referred responders reported reduced(More)
BACKGROUND Neurosteroids have been proposed to play an important role in the interaction between alcohol and GABA(A) receptors and for the symptomatology of premenstrual dysphoric disorder (PMDD). The primary aim of this study was to investigate possible alcohol-induced changes in allopregnanolone serum concentrations across different menstrual cycle phases(More)
Vocalizations of Senegal and South African lesser bushbabies were compared with respect to their acoustic properties analysed from spectrograms and oscillograms. Homologous calls could be identified within comparable functional categories. Considerable similarities were revealed in most of the noisy vocalizations associated with aggressive, defensive or(More)
Increased precipitation is one projected outcome of climate change that may enhance the discharge of freshwater to the coastal zone. The resulting lower salinity, and associated discharge of both nutrients and dissolved organic carbon, may influence food web functioning. The scope of this study was to determine the net outcome of increased freshwater(More)
perspectives on the use of a computer-based concept for lifestyle intervention implemented in Abstract Objective The aim of this study was to evaluate staff experiences of the usage of a computer-based concept for lifestyle testing and tailored advice implemented in routine primary health care (PHC). Design The design of the study was a cross-sectional,(More)
BACKGROUND Bridging the knowledge-to-practice gap in health care is an important issue that has gained interest in recent years. Implementing new methods, guidelines or tools into routine care, however, is a slow and unpredictable process, and the factors that play a role in the change process are not yet fully understood. There is a number of theories(More)
