WHAT IS THE BEST METHOD TO EVALUATE RETINAL MICROCIRCULATION?

Artery Research, 2015
The microvasculature of retinal ganglion cell layer, which is the part of central nervous system, can be investigated non-invasively in human. For clinical routine the fluorescence angiography is used to test patency and leak of retinal or choroid ...

Effects of tempol on renal medullary tissue hypoxia in an ovine model of Gram‐negative septic acute kidney injury

Experimental Physiology, EarlyView.
Abstract Renal arterial infusion of tempol (RAT) at the onset of Gram‐negative sepsis can prevent sepsis‐induced medullary tissue hypoxia and acute kidney injury (AKI). However, it is not known whether treatment with tempol at a clinically relevant time point of sepsis is similarly effective. Thus, we examined whether tempol can reverse renal medullary

Choroidal Laser Doppler Flowmetry in Healthy Subjects [PDF]

Archives of Ophthalmology, 2000
To evaluate normal choroidal blood flow and its relationship with various factors such as age, systemic blood pressure, and intraocular pressure (IOP).A total of 70 healthy subjects were recruited. Choroidal blood flow was assessed using a method based on laser Doppler flowmetry (LDF) technique.

Individuals with persisting post‐concussion symptoms with physiological subtype demonstrate altered cardiovascular and autonomic responses to face cooling

Experimental Physiology, EarlyView.
Abstract Individuals with persisting post‐concussion symptoms with physiological subtype (PPCS‐P) demonstrate exercise intolerance due to exacerbation of concussion‐like symptoms during incremental exercise. We tested the hypothesis that individuals with PPCS‐P (n = 12) would have a blunted cardiac autonomic response to face cooling compared to healthy

Influence of menstrual cycle phase on inflammatory and vascular responses to acute passive heating in healthy young women

Experimental Physiology, EarlyView.
Abstract The aim of this study was to determine whether inflammatory and vascular responses to passive heating differ between the early follicular phase (EFP) and the mid‐luteal phase (MLP) of the menstrual cycle. Ten healthy, naturally menstruating females (26 ± 3 years of age; body mass index 21.4 ± 1.9 kg/m2) were assessed during EFP and MLP ...

Increases in skin perfusion and blood oxygen in the non‐exercising human limbs during exercise in the heat: Implications for control of circulation

Experimental Physiology, EarlyView.
Abstract Blood flow in the inactive limb tissues and skin is widely thought to decline during incremental exercise to exhaustion due to augmented sympathoadrenal vasoconstrictor activity, but direct evidence to support this view is lacking. Here, we investigated the inactive‐forearm haemodynamic (Q̇forearm${\dot{Q}}_{\mathrm{forearm}}$) and oxygenation

Single camera three component planar velocity measurements, using two frequency Planar Doppler Velocimetry (2v-PDV) (2005) [PDF]

, 2005
The work presented here describes a method that allows three component velocity measurements to be made, quickly and non-intrusively, across a plane in a flow defined by a laser light sheet. The method, two frequency planar Doppler Velocimetry (2v-PDV)

Sex differences in cerebral blood flow and cardiac function in response to exercise in the heat

Experimental Physiology, EarlyView.
Abstract We investigated the effect of exercising in hot conditions on cerebral blood flow and systolic left ventricular (LV) function in males and females, to explore sex differences. The experimental condition consisted of walking on a treadmill at 5 km/h and 2% incline, inside a heat chamber at 40°C (50% relative humidity), for 90 min.
