Cerebrovascular pulsatility following long duration spaceflight is associated with changes in pulse pressure and carotid artery stiffness

Experimental Physiology, EarlyView.
Abstract Central artery stiffening increases the haemodynamic pulsations transmitted downstream towards target organs, including the brain. While recent evidence suggests that long duration spaceflight is associated with reduced common carotid artery (CCA) distensibility, cerebrovascular pulsatility has not been extensively characterized in astronauts.

Integrative cardiovascular dose–response to graded lower‐body negative pressure

Experimental Physiology, EarlyView.
ABSTRACT Lower‐body negative pressure (LBNP) has been posited as a potential spaceflight countermeasure to counteract the physiological deconditioning related to fluid shifts in microgravity. However, open questions remain regarding the magnitude of LBNP that should be applied.

Trimethylamine N‐oxide is elevated in postmenopausal women relative to age‐matched men and premenopausal women among individuals with obesity

Experimental Physiology, EarlyView.
Abstract Trimethylamine N‐oxide (TMAO) is linked to arterial stiffness and atherosclerosis. Cardiovascular disease (CVD) risk increases following menopause in women. Whether menopause influences plasma TMAO metabolism to mediate CVD risk is unknown.

Exploitation of a pH-sensitive hydrogel for CO2 detection [PDF]

, 2003
In this paper is described how hydrogel is exploited as sensor material for the \ud detection of carbon dioxide (CO2). A pH-sensitive hydrogel disc, which swells and deswells in response to pH changes, was clamped between a pressure sensor membrane and a

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 ...

Evidence of racial differences in peripheral blood pressure, central haemodynamics and arterial stiffness between young Black and White women

Experimental Physiology, EarlyView.
Abstract Hypertension diagnosed via peripheral (brachial) blood pressure (pBP) is a strong independent predictor of overt cardiovascular disease (CVD). However, central (aortic) blood pressure (cBP), which is influenced by arterial stiffness, may be more strongly associated with CVD risk. Young Black women (BLW) demonstrate higher pBP than White women (
