the impact of climatic variations on basal area growth of basswood (ba) (tilia americana l.), american beech (be) (fagus grandifolia enrh.), bitternut hickory (bh) (caria cordiformis (wang.) k. koch), largetooth aspen (la) (populus grandidentata michx.), red maple (rm) (acer rubrum l.), red oak (ro) (quercus rubra l.), sugar maple (sm) (acer saccharum marsh.), and white ash (wa) (fraxinus a...

introduction quantitative susceptibility mapping (qsm) is a new contrast mechanism in magnetic resonance imaging (mri). the images produced by the qsm enable researchers and clinicians to easily localize specific structures of the brain, such as deep brain nuclei. these nuclei are targets in many clinical applications and therefore their easy localization is a must. in this study, we aimed to i...

conclusion statistical analysis of susceptibilities of ms patients versus healthy subjects found no excess deposition of calcium content in deep gray matter of ms patients. calcification may not be considered as a biomarker of prognosis in ms. results magnetic susceptibility(x) of calcium content was assessed by number of pixels induced by gp and put in ms patients as well as healthy subjects. ...

Amyloid protein can damage nerve cells through a variety of biological mechanisms including oxidative stress, alterations in calcium homeostasis, and proapoptosis. Edaravone, a potent free radical scavenger possessing antioxidant effects, has been proved neuroprotective effect in stroke patients. The current study aimed to investigate the effects of EDA in an Aβ-induced rat model of AD, by stud...

We performed experiments in alpha-chloralose-anesthetized rabbits with vagi sectioned, to determine the influence of intravenous and intracerebroventricular vasopressin on arterial baroreflex control of renal nerve activity. Arterial baroreflex control of renal nerve activity was assessed during phenylephrine-induced increases and nitroglycerin-induced decreases in arterial pressure. Intravenou...

introduction:dystonia is a disorder of movement caused by various etiologies. laryngeal dystonia is caused by the spasm of laryngeal muscles. it is a disorder caused by vocal fold movement in which excessive adduction or abduction of the vocal folds occurs during speech. the pathophysiology of this type of dystonia is not fully known. some researchers have suggested that basal ganglia structure...

fahr’s disease is a progressive and idiopathic basal ganglia calcification with normal metabolism of calcium and phosphor with motor and psychiatric signs and symptoms. dementia, chorea attetosise, psychosis and depression due to fahr’s disease are frequently reported, but fahr,s disease with bipolar mood disorder manifestation is very rare and we found only 3 case in review of literature from ...
