A study of sea ice biota was carried out in the Gulf of Bothnia (northern Baltic Sea) during the winter of 1989–1990. Samples (ice cores) were taken at a coastal station at regular time intervals during the ice season. Chlorophyll a concentration, algal species distribution, bacterial numbers, and primary and bacterial production were measured. Colonization(More)
The behavioral effects of allopregnanolone (3α-hydroxy-5α-pregnan-20-one) in women are not known. 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 behavioral effects of(More)
Autotrophic and heterotrophic growth characteristics of a nano-flagellate were investigated. The flagellate,Ochromonas sp., was isolated from the northern Baltic Sea. Autotrophic growth was poor. Axenically pregrown flagellates did not increase significantly in cell number during incubation in different inorganic media. The number of flagellates remained(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)
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)
During the 1990s most western European and Organization of Economic Cooperation and Development (OECD) countries experienced financial difficulties and were forced to cut back on or restrain health care expenditures. Home rehabilitation has received attention in recent years because of its potential for cost containment. Often forgotten, however, is the(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)
BACKGROUND It is still unknown whether the fatty acid composition of human skeletal muscle lipids is directly influenced by the fat composition of the diet. OBJECTIVE We investigated whether the fatty acid composition of the diet is reflected in the fatty acid profile of skeletal muscle phospholipids and triacylglycerols. DESIGN Thirty-two healthy(More)
High intakes of whole grain foods are inversely related to the incidence of coronary heart diseases and type 2 diabetes, but the mechanisms remain unclear. Our study aimed to evaluate the effects of a diet rich in whole grains compared with a diet containing the same amount of refined grains on insulin sensitivity and markers of lipid peroxidation and(More)
