Therefore, the in vivo efficacy was studied. Low-density lipoprotein receptor-knockout (LDLR(-/-)) mice were fed a high cholesterol diet (0.15%) for two months to measure the atherogenic areas of the hearts and aortas. When triacsin C was orally administered (10 mg/kg/day), the atherosclerotic areas were significantly reduced by 86% in aorta and 36% in hearts. The results strongly suggested that triacsin
C shows anti-atherogenic activity by inhibiting acyl-CoA synthetase activity.”
“Object. The purpose of this study was to use MRI and histology to compare stereotactic lesioning modalities in a large brain model of Integrin inhibitor thalamotomy.\n\nMethods. A unilateral thalamotomy was performed in piglets utilizing one of 3 stereotactic lesioning modalities: focused ultrasound (FUS), radiofrequency, and radiosurgery. Standard clinical lesioning parameters selleck chemicals llc were used for each treatment; and clinical, MRI, and histological assessments were made at early (<72 hours), subacute (1 week), and later (1-3 months) time intervals.\n\nResults. Histological and MRI assessment showed
similar development for PUS and radiofrequency lesions. T2-weighted MRI revealed 3 concentric lesional zones at 48 hours with resolution of perilesional edema by 1 week. Acute ischemic infarction with macrophage infiltration was most prominent at 72 hours, with subsequent resolution of the inflammatory reaction and coalescence of the necrotic selleck inhibitor zone. There was no apparent difference in ischemic penumbra or “sharpness” between FUS or radiofrequency lesions. The radiosurgery lesions presented differently, with latent effects, less circumscribed lesions at 3 months, and apparent histological changes seen in white matter beyond the thalamic target. Additionally, thermal and radiation lesioning gradients were compared with modeling by dose to examine the theoretical penumbra.\n\nConclusions. In swine thalamus, FUS and radiosurgery lesions evolve similarly as determined by MRI,
histological examination, and theoretical modeling. Radiosurgery produces lesions with more delayed effects and seemed to result in changes in the white matter beyond the thalamic target.”
“Objectives. This study tested the hypothesis that patients with depression show less and later declines into lower EEG vigilance stages (different global functional brain states) under resting conditions than healthy controls, as proposed by the vigilance theory of affective disorders. Methods. Thirty patients with Major Depressive Disorder (19 female; mean age: 37.2 years, SD: 12.6) without psychotropic medication and 30 carefully age-and sex-matched controls (19 female; mean age: 37.3 years, SD: 12.8) without past or present mental disorders underwent a 15-min resting EEG.
