Modeling functional network topology following stroke through graph theory: functional reorganization and motor recovery prediction
Braz J Med Biol Res. 2022 Aug 15;55:e12036. doi: 10.1590/1414-431X2022e12036. eCollection 2022.ABSTRACTThe study of functional reorganization following stroke has been steadily growing supported by advances in neuroimaging techniques, such as functional magnetic resonance imaging (fMRI). Concomitantly, graph theory has been increasingly employed in neuroscience to model the brain's functional connectivity (FC) and to investigate it in a variety of contexts. The aims of this study were: 1) to investigate the reorganization of network topology in the ipsilesional (IL) and contralesional (CL) hemispheres of stroke patients wi...

Role of aerobic physical training on cardiac autonomic and morphophysiological dysfunction in hypertensive rats subjected to ovarian hormone deprivation
Braz J Med Biol Res. 2022 May 16;55:e11916. doi: 10.1590/1414-431X2022e11916. eCollection 2022.ABSTRACTHere we investigated the effects of physical training on cardiovascular autonomic control and cardiac morphofunctional parameters in spontaneously hypertensive rats (SHRs) subjected to ovarian hormone deprivation. Forty-eight 10-week-old SHRs were divided into two groups: ovariectomized (OVX, n=24) and sham (SHAM, n=24). Half of each group (n=12) was trained by swimming for 12 weeks (OVX-T and SHAM-T). Cardiac morphology and functionality were assessed using echocardiography, and autonomic parameters were assessed using d...

Correlation of common inflammatory cytokines with cognition impairment, anxiety, and depression in acute ischemic stroke patients
In conclusion, common inflammatory cytokines including TNF-α, IL-1β, and IL-17 were related to cognition impairment, anxiety, or depression in AIS patients.PMID:35239774 | DOI:10.1590/1414-431X2021e11517
