Men and women show a rapid antidepressant response following scop

Men and women show a rapid antidepressant response following scopolamine, but the magnitude of response is larger in women than in men. Neuropsychopharmacology (2010) 35, 2479-2488; doi: 10.1038/npp.2010.131; published online 25 August 2010″
“Non-neonatal hypoxic-ischemic encephalopathy is a clinical condition often related to cardiopulmonary arrest that demands critical management and treatment decisions. Management depends

mainly on the degree of neurological impairment and prognostic considerations. Computed tomography (CT) is often used to exclude associated or mimicking pathology. If any, only check details nonspecific signs such as cerebral edema, sulci effacement, and decreased gray matter (GM)/white matter (WM) differentiation are evident. Pseudosubarachnoid hemorrhage, a GM/WM attenuation ratio < 1.18, and inverted GM attenuation are associated with a poor prognosis. Magnetic resonance

(MR) imaging is more sensitive than CT in assessing brain damage in hypoxic-ischemic encephalopathy. Some MR findings have similarities to those seen pathologically, based on spatial distribution and time scale, such as lesions distributed in watershed regions and selective injury to GM structures. In the acute phase, lesions are better depicted using diffusion-weighted imaging (DWI) because of the presence of cytotoxic edema, which, on T2-weighted images, only become apparent later in the early subacute phase. In the late subacute phase, postanoxic leukoencephalopathy BAY 1895344 molecular weight and contrast enhancement could be observed. In the chronic phase, atrophic changes predominate over tissue signal changes. MR can be useful for estimating prognosis when other tests are inconclusive. Some findings, such as the extent of lesions on DWI and presence of a lactate peak and depleted N-acetyl aspartate peak on MR spectroscopy, seem to have prognostic value.”
“Proton (H-1) magnetic resonance spectroscopy (MRS) changes are noted in Wilson’s disease (WD). However, see more there are no studies regarding membrane phospholipid abnormality using P-31

MRS in these patients. We aimed to analyze the striatal spectroscopic abnormalities using P-31 and H-1 MRS in WD.

Forty patients of WD (treated, 29; untreated,11) and 30 controls underwent routine MR image sequences and in vivo 2-D P-31 and H-1 MRS of basal ganglia using an image-selected technique on a 1.5-T MRI scanner. Statistical analysis was done using Student’s t test.

The mean durations of illness and treatment were 6.2 +/- 7.4 and 4.8 +/- 5.9 years, respectively. MRI images were abnormal in all the patients. H-1 MRS revealed statistically significant reduction of N-acetyl aspartate (NAA)/choline (Cho) and NAA/creatine ratios in striatum (H-1 MRS) of treated patients compared to controls. The mean values of phosphomonoesters (PME) (p < 0.0001), phosphodiesters (PDE) (p < 0.0001), and total phosphorus (TPh) (p < 0.0001) were elevated in patients compared to controls.
