BACKGROUND: Clinic post-exercise hypotension (PEH) is different after aerobic exercise performed in the morning and in the evening. Thus, ambulatory PEH should also differ after exercises conducted at different times of day. However, because of the circadian pattern of BP, ambulatory PEH should be assessed considering a control condition. Thus, this study was designed to verify the effects of morning and evening exercises on post-exercise ambulatory BP averages and circadian parameters by comparing responses obtained at each time of day after an exercise and a control session...

BACKGROUND: In 2010, there were approximately 2.2 million emergency room visits associated with traumatic brain injury (TBI), with 80 percent diagnosed as mild TBI or concussion. In addition, there are a large number of TBIs, especially mild TBIs, which go either unreported by patients or initially undiagnosed by clinicians. Our team has previously identified a panel of immune-related genes that can diagnose ischemic stroke at triage, and due to shared pathophysiological mechanisms of TBI and stroke, we hypothesized that this panel of genes may also be utilized for the diagnosis of TBI...

Alzheimer's disease (AD) is a slow, progressive neurodegenerative disease in which cognitive decline takes place over a period of several years with a very variable period of mild cognitive impairment (MCI) and, in some cases, relatively long period before progression to dementia. The cognitive deficit during MCI is probably due to neuronal loss, an intermediate level of amyloid-β (Aβ) plaques and neurofibrillary tangles (NFT) and synaptosis, which is interrupted with a transient compensatory increase. We found impairment in reference memory accompanied by a decrease in the expression of synaptophysin, β-III tubulin, and MAP2 and a trend for GluR1, at 12 weeks of age in 3xTg-AD mice (hAPPSwe, P301L tau, PS1 [M146V] knock-in), a widely used transgenic model of AD...
