Depression and apathy were the most frequent PSs detected after stroke. Premorbid psychopathologies and right-hemisphere location were the main predictive indicators of early and long-term PSs. (The Journal of Neuropsychiatry and Clinical Neurosciences 2011; 23:340-347)”
“We present a density functional theory based Bader analysis

of the charge distribution in pure and hydrogenated SrTiO(3). We find that the hydrogen defect carries a +0.56e charge and the OH defect carries a +0.50e charge compared to the host oxygen. Calculations on BaNbO(3), CaTiO(3), and SrZrO(3) support these findings. The distribution of the remaining electronic density decays see more exponentially with distance to the hydrogen defect. Diffusional paths are calculated wherein the hydrogenic species retain a charge between +0.57 and +0.54e showing that hydrogen permeation should not be viewed as consisting of virtually independent protonic and electronic transport processes.

“Angiopoietins (Angs) are important angiogenic and endothelial cell growth factors with many functions, including influence on the vascular wall. Pulse-wave velocity (pwv) is an independent marker of cardiovascular

selleck products adverse outcome in hypertensives, although all the pathophysiological mechanisms that affect it have not yet been determined. We investigated the relationship between arterial stiffness and Ang-1 and Ang-2 gene expression in the peripheral blood monocytes of hypertensive patients. We studied 53 patients who had untreated grade-1 or grade-2 essential hypertension and no indications of other organic heart disease. Carotid-femoral (c-f) and carotid-radial (c-r) artery waveforms were measured and pwv was determined. The monocytes were isolated using anti-CD14(+) antibodies

and mRNAs were estimated by real-time quantitative reverse transcription-PCR. Ang-1 gene expression was strongly correlated with both c-f-pwv (r=0.952, P<0.001) and c-r-pwv (r=0.898, P<0.001). Similarly, Ang-2 gene expression Vorinostat in vitro was significantly correlated with both c-f-pwv (r=0.471, P=0.002) and c-r-pwv (r=0.437, P=0.003). Our data provide important evidence that Ang-1 and Ang-2 gene expression levels in peripheral monocytes are closely related with pwv in patients with essential hypertension. This positive correlation may suggest a link between angiogenesis and arterial stiffness in those patients.

“Efficacy of repetitive, transcranial magnetic stimulation (rTMS) has been found in depression; however, doubt still remains about its effectiveness in clinical practice. In this context, results are being explored.
