Chronic physical activity mitigates cerebral hypoperfusion during central hypovolemia in elderly humans

Autor: Kevin J. Formes, Frederick Schaller, Xiangrong Shi, Peizhen Zhang, Nancy Tierney

Publikováno v: American Journal of Physiology-Heart and Circulatory Physiology. 298:H1029-H1037

This study sought to test the hypothesis that orthostasis-induced cerebral hypoperfusion would be less severe in physically active elderly humans (ACT group) than in sedentary elderly humans (SED group). The peak O2 uptake of 10 SED (67.1 ± 1.4 yr)

The cause of the age-related impairment of arterial baroreflex function remains ill-defined; moreover, it is unknown whether this impairment results from aging per se or from an inactive lifestyle associated with aging. In this study, we sought to: 1

Cerebral autoregulation is preserved during orthostatic stress superimposed with systemic hypotension

Autor: Scott A. Smith, Peter B. Raven, Frederic Schaller, Xiangrong Shi, Hong Guo, Nancy Tierney

Publikováno v: Journal of Applied Physiology. 100:1785-1792

We sought to determine whether cerebral autoregulation (CA) is compromised during orthostatic stress superimposed with systemic hypotension. Transient systemic hypotension was produced by deflation of thigh cuffs previously inflated to suprasystolic

Strategic leukocyte depletion reduces pulmonary microvascular pressure and improves pulmonary status post-cardiopulmonary bypass

Autor: C A Ferrara, N Wallace, Albert H Olivencia-Yurvati, Robert T. Mallet, Nancy Tierney

Publikováno v: Perfusion. 18:23-31

Cardiopulmonary bypass (CPB) precipitates inflammation that causes marked pulmonary dysfunction. Leukocyte filtration has been proposed to reduce these deleterious effects. Other studies show an improvement with aprotinin. We proposed that a combinat
