Physical exercise ameliorates age-related neuronal loss and is currently recommended as a therapeutical aid in several neurodegenerative diseases. However, evidence is still lacking to firmly establish whether exercise constitutes a practical neuroprotective strategy. We now show that exercise provides a remarkable protection against brain insults of different etiology and anatomy. Laboratory r...

brain single-photon emission computerized tomography (spect), in particular, with perfusion agents or with neuroreceptor imaging radiopharmaceuticals, is rapidly becoming a clinical tool in many neurologic and psychiatric conditions. this imaging modality has been used for diagnosis, prognosis assessment, evaluation of response to therapy, risk stratification, detection of benign vs. malignant ...

Physical exercise promotes neural plasticity in the brain of healthy subjects and modulates pathophysiological neural plasticity after sensorimotor loss, but the mechanisms of this action are not fully understood. After spinal cord injury, cortical reorganization can be maximized by exercising the non-affected body or the residual functions of the affected body. However, exercise per se also pr...

Background and Objective: Computerized tomography and fluoroscopic computerized tomography are amongst the methods used for guiding needle biopsy processes; however, fluoroscopic computerized tomography demonstrates the images during the process of biopsy. This study aims to compare and contrast the success of biopsy under guide...

During exercise: the Kety-Schmidt-determined cerebral blood flow (CBF) does not change because the jugular vein is collapsed in the upright position. In contrast, when CBF is evaluated by (133)Xe clearance, by flow in the internal carotid artery, or by flow velocity in basal cerebral arteries, a approximately 25% increase is detected with a parallel increase in metabolism. During activation, an...

bstract—Exercise is an important facet of behavior that nhances brain health and function. Increased expression of he plasticity molecule brain-derived neurotrophic factor BDNF) as a response to exercise may be a central factor in xercise-derived benefits to brain function. In rodents, daily heel-running exercise increases BDNF gene and protein evels in the hippocampus. However, in humans, exer...
