Elevated blood levels of S100B in neuropsychiatric disorders have so far been mainly attributed to glial pathologies. However, increases or dysfunction of adipose tissue may be alternatively responsible. Our study assessed S100B serum levels in 60 adult subjects without a prior history of neuropsychiatric disorders. S100B concentrations were closely(More)
Impaired glucose metabolism and the development of metabolic syndrome contribute to a reduction in the average life expectancy of individuals with schizophrenia. It is unclear whether this association simply reflects an unhealthy lifestyle or whether weight gain and impaired glucose tolerance in patients with schizophrenia are directly attributable to the(More)
The present study in the South American rodent Octodon degus shows for the first time that the postnatal development of hypothalamic-pituitary-adrenal axis function in this semi-precocial species differs from that of altricial rodents, i.e. rats or mice, in several aspects. Our experiments revealed a particular pattern of hypothalamic-pituitary-adrenal axis(More)
Elevated blood levels of S100B in schizophrenia have so far been mainly attributed to glial pathology, as S100B is produced by astro- and oligodendroglial cells and is thought to act as a neurotrophic factor with effects on synaptogenesis, dopaminergic and glutamatergic neutrotransmission. However, adipocytes are another important source of S100B since the(More)
Aims. To evaluate 3 strategies to reduce weight in obese families. Research design and methods. 142 obese parents and 119 obese children kept a fat-calorie restriction diet. On top of this diet, the families were randomized in a three-factorial design to one or more of three weight-loss strategies: (1) an additional diet preferring carbohydrates having a(More)
Previous studies of lymphocyte distribution in schizophrenia have yielded inconsistent results, as summarized in the present study. Based on our own original data, potential confounds that might explain these variations are analyzed and discussed. Blood samples from 26 patients with acute paranoid schizophrenia were investigated in comparison with 32(More)
Increased S100B serum levels have been considered as a marker of glial pathology, brain damage, and blood-brain-barrier impairment. However, S100B expression has also been detected outside the nervous system, suggesting that altered S100B serum levels may not exclusively reflect brain-specific pathologies. Notably, S100B secretion in adipocytes seems to be(More)
Elevated plasma concentrations of homocysteine, a sulfur-containing amino acid, are a risk factor for coronary, cerebral and peripheral artery disease. Next to other factors, drugs used for the prevention or treatment of cardiovascular disease may modulate plasma homocysteine levels. Thus, a drug induced homocysteine increase may counteract the desired(More)
Magnetic resonance imaging and postmortem studies on schizophrenia provided evidence for compromised myelin integrity and reduced numbers of oligodendrocytes, which may worsen during the disease course. However, it is not clear whether these findings result from disease-inherent oligodendrocyte degeneration or side effects of antipsychotic treatment.(More)
