5HT2A receptors were measured in the frontal cortex from schizophrenic and non-schizophrenic subjects. There was a decrease in the density of 5HT2A receptors in Brodmann's areas 8, 9 and 10 from the schizophrenic subjects. In addition, there was an age-dependent decrease in the density of 5HT2A receptors in Brodmann's areas 9 from the non-schizophrenic(More)
Having shown a decrease in serotonin2A receptors in the dorsolateral prefrontal cortex (DLPFC) from schizophrenic subjects, we have now determined if this change was reflective of widespread changes in neurochemical markers in DLPFC in schizophrenia. In Brodmann's area (BA) 9 from 19 schizophrenic and 19 control subjects, we confirmed a decrease in the(More)
The binding of [3H]paroxetine and [3H]ketanserin to particulate membranes from frontal cortex of subjects who had or did not have schizophrenia was measured as was [3H]paroxetine binding to particulate membranes from the hippocampus and caudate nucleus. There was no change in either the affinity or density of [3H]ketanserin binding to membranes from the(More)
There have been repeated reports of a decrease in serotonin2A receptors in the frontal cortex from subjects with schizophrenia. Similarly, in rats treated with antipsychotic drugs, it has been shown that many antipsychotic drugs decrease cortical serotonin2A receptors, an affect not seen with the antipsychotic drug haloperidol. We therefore compared the(More)
The A(-1438)G promoter polymorphism of the 5-hydroxytryptamine 2a receptor (5-HT2AR) gene and its influence on the cortical density of 5-HT2AR was studied using brain tissue donated at autopsy from 58 schizophrenic and 64 non-schizophrenic subjects. A linkage between genotypes for the A(-1438)G and a T102C polymorphic site identified in a previous study was(More)
BACKGROUND Lung ultrasound is a novel technique for detecting generalized fluid overload in children and adults with end-stage renal disease (ESRD). Echocardiography and bioimpedance spectroscopy are established methods, albeit variably adopted in clinical practice. We compared the practicality and accuracy of lung ultrasound with current objective(More)
