The computer system includes a receptor field with sensors, each of which receives data with specific characteristics. These data are passed to processors, whereby only those connections between sensors and processors are released that are suited for an evaluation of the data according to a combination of specific data dictated by a phase program circuit. The computer system also includes a selector circuit that discards those dictated program commands that lead to a “senseless” computation result. A motor program circuit for the control of effectors may be connected to the computer system which at least contributes to the movement of the receptor field in order to bring the receptor field closer to suitable data with specific characteristics for better execution of the program. From disorders of the computer system implications are deduced for the pathophysiology of the schizophrenic syndrome. Finally, a novel treatment approach to this syndrome is proposed.展开更多

Although studies of its substrates are abundant [ 1, 2], and ABCB1 is a well-conserved gene, there is increasing evi- dence that its polymorphisms affect substrate specificity [3]. A previous study reported that the synonymous single nucleotide polymorphism （SNP） C3435T （rs1045642） affects the timing of co-translational folding and insertionof P-gp into the membrane,展开更多

Fourteen schizophrenia-treatment resistant patients, recruited for this study, were treated with clozapine for 45 days. Patient health improvement was assessed before and after each cycle of two weeks of clozapine therapy, using the Brief Psychiatric Rating Scale (BPRS). Plasma clozapine and norclozapine concentrations were determined by high-performance liquid chromatography (HPLC). No significant correlations between plasma clozapine and norclozapine concentrations and clinical health improvement among our schizophrenic patients were found. However, a significant correlation was observed between clinical health improvement given by BPRS scores and norclozapine plasma concentration to daily clozapine dose ratio (NCZ/D). Despite the small sample size of our study, our findings suggest that the clozapine therapy response variations observed in our patients may be, in part, explained by the interindividual differences in plasma norclozapine concentration to clozapine dose ratio (NCZ/D). So the NCZ/D parameter could be used as a good indicator for adjusting the clozapine dose-adaptation strategy and consequently for improving the clinical psychopathological state of schizophrenia-treatment resistant patients.展开更多

I should like to give a brief overview of the role that some new methods are playing in this emerging area of physiological bioenergetics, supported by a few references to our contributions as I scarcely have the faculties now to understand other specific contributions. This new field is brimming with promises for medicine, science and society, in general. I cannot and must not be concrete or comprehensive, because I honestly feel that it is now that matters are really beginning to take off, assisted by the most appropriate international capabilities.展开更多
