Altered cerebral hemodyamics and cortical thinning in asymptomatic carotid artery stenosis. [PDF]

PLoS ONE, 2017
Cortical thinning is a potentially important biomarker, but the pathophysiology in cerebrovascular disease is unknown. We investigated the association between regional cortical blood flow and regional cortical thickness in patients with asymptomatic ...

Phosphomimetic modulation of eNOS improves myocardial reperfusion and mimics cardiac postconditioning in mice. [PDF]

PLoS ONE, 2014
Myocardial infarction resulting from ischemia-reperfusion injury can be reduced by cardiac postconditioning, in which blood flow is restored intermittently prior to full reperfusion.

Characterization of Systemic and Regional Hemodynamics and Vascular Dysfunction in Mice with Fecal Induced Peritonitis

Biomedicines, 2022
Sepsis is associated with circulatory dysfunction contributing to disturbed blood flow and organ injury. Decreased organ perfusion in sepsis is attributed, in part, to the loss of vasoregulatory mechanisms.
