The Contribution of Nitric Oxide to the Skin Blood Flow Response to Exercise in Boys and Men
In response to heat stress, children sweat less than adults. However, little is known about their skin blood flow (SkBF) response. We investigated child-adult differences in SkBF during exercise (30 min at 60% VO2max) and local heating (44℃) in 12 boys (9.71.2 y) and 12 men (22.22.0 y) using …

Effect of Selective and Nonselective Cyclooxygenase Enzyme Inhibition on Arterial Blood Pressure and Cerebral Blood Flow with Exposure to Intermittent Hypoxia in Humans
… (IH) simulating obstructive sleep apnea raises blood pressure (BP) and impairs cerebral blood flow response. The pathophysiology of intermittent hypoxia-mediated increase in BP involves multiple mechanisms but the role of cyclooxygenase (COX) catalyzed vasoactive prostaglandins (PG) is unclear. …

Optical Imaging Of Tissue Physiology With Exogenous Contrast Agents
… of experiments concurrently measured cerebral blood flow and bothintravascular- and extravascular-tissue oxygen concentration in a rat brain during functional activation; the new instrumentation needed to collect this information used contrast agent phosphorescence lifetime to determine oxygen …

Physiological Effects of Vibration in Select Populations
… results in significant increases in skin blood flow. No study has determined if there is an optimal frequency or duration for optimizing this response. In addition, there is no known mechanism for the increase in skin blood flow. It is hypothesized that nitric oxide (NO) is responsible for …

Investigating mechanisms of hemodynamic control in the brain
… is the relationship between neural activity and blood flow that allows the brain to exhibit increases in blood flow to areas of elevated neural activity during sensory stimulation. It is these localized changes in blood flow, collectively known as the hemodynamic response, that are detected by …

Assessment of the Impact of Loading Pressure on Endothelial Function in Diabetic Foot
… on endothelial function of the superficial skin blood vessels on both aspects of the foot in subjects with Type 2 diabetes mellitus in comparison to a group of control without diabetes.<b><br/></b><b><br/></b><b>Methods</b>: In-shoe pressure experienced on dorsal and plantar surfaces of the foot …

Blood flow responses in the human calf to superficial cold applications and exercise
… exercise would affect the vasodilatory response in the plantar-flexor muscles of the calf. Fourteen healthy, uninjured male subjects, of college age, participated in 4 randomized treatments applied on separate days: Control (CO), Ice Pack only (I), Exercise only (EX), and Ice and …

Mechanisms of Control of Blood Flow in the Forelimb of Sheep
… about the factors involved in the control of blood flow, the cellular mechanisms of their action are poorly understood. This study investigated the mechanisms of norepinephrine, epinephrine, isoproterenol, and acetylcholine.</p> <p>First, in a constant pressure/variable flow preparation we …

Effect of a Single High-Fat Meal and Vitamins on the Circulatory Response to Local Heat in Koreans and Caucasians
Blood flow mediated by the vascular endothelium plays an important role in removing heat from the skin. Asians who have thrifty genes have impaired endothelial function (EF) due to the westernized high fat (HF) dietary lifestyle. Hypertriglyceridemia (HTG) can produce free radicals which reduces …

ENHANCING EXERCISE PERFORMANCE THROUGH ISCHAEMIC PRECONDITIONING
… be mediated through altering exercise-induced blood flow and/or vascular function. Study 2 (Chapter 4) investigated the blood flow response to exercise, using ultrasound, when exercise was preceded by a control (SHAM) condition, or either local or Remote (R)IPC in eighteen recreationally …
