Disturbed neural development has been postulated as a crucial factor in the pathophysiology of schizophrenic psychoses. The neurobiochemical basis for such changes of cytoarchitecture and changed neural plasticity could involve an alteration in the regulation of neurotrophic factors. In order to test this hypothesis, BDNF and NT-3 levels in post-mortem(More)
The search for the causes of neurodegenerative disorders is a major theme in brain research. Acquired disturbances of several aspects of cellular metabolism appear pathologically important in sporadic Alzheimer's disease (SDAT). Among these brain glucose utilisation is reduced in the early stages of the disease and the regulatory enzymes important for(More)
OBJECTIVE After discontinuation of neuroleptic drugs, their antipsychotic and antiparkinsonian effects are still present for a prolonged period. It is not known whether the extended effects of neuroleptic drugs in humans are due to the continued presence of drug in brain tissue or to long-lasting drug-induced physiologic changes. The aim of this study was(More)
INTRODUCTION A growing body of evidence suggests that the glial cell line-derived neurotrophic factor (GDNF) is involved in the aetiopathology of mood disorders. GDNF is a neurotrophic factor from the transforming growth factor-beta-family, playing a role in cell development and function in the limbic system. This is the first study to examine GDNF(More)
The density of nicotinic alpha4beta2 receptors, which are believed to largely mediate nicotine's effects, has been reported to be decreased in post-mortem hippocampus of patients with schizophrenia. In the present study, using [(3)H]cytisine as a radioligand, we observed a significant 30% decrease in post-mortem striatum of patients with schizophrenia(More)
This paper presents data obtained in a one-day census investigation in five European countries (Austria, Hungary, Romania, Slovakia, Slovenia). The census forms were filled in for 4191 psychiatric inpatients. Concerning legal status, 11.2% were hospitalised against their will (committed) and 21.4% were treated in a ward with locked doors. There was only a(More)
Substantia nigra pars compacta of seven patients who had died of Parkinson's disease, has been investigated for the iron-depending aconitase (reactions I and II). In addition we analysed respiratory chain enzymes. While complex I activity of the respiratory chain was significantly reduced, other enzymes of this pathway were unaltered. The citric acid cycle(More)
Prefrontal cortical (PFC) and hippocampal (HI) volume reductions have been consistently found in patients with recurrent depressive disorder (DD). Here we examine the possibility that oxidative stress, widely implicated in neuronal cell damage, may contribute to these brain structural changes. We compared manganese (Mn) and copper/zinc (Cu/Zn) superoxide(More)
OBJECTIVE The aim of this study was to examine concentrations of levomepromazine and its metabolite desmethyl-levomepromazine in different regions of human brain and in relationship to drug-free time. METHODS Drug concentrations were measured in up to 43 regions of 5 postmortem human brains of patients previously treated with levomepromazine. To enable(More)
our results using the Fast Fourier Transformation, the N-body attraction problem, and the cubic splines interpolation as examples. We investigate the application of partial evaluation to numerically oriented computation in scientific and engineering applications. We present our results using the Fast Fourier Transformation, the N-body attraction problem,(More)
