Ageing reveals the latent effects of early life stress on respiratory and metabolic function in female rats: Novel insights into the sex‐specific origins of sleep apnoea

open access: yesExperimental Physiology, EarlyView.
Abstract Sleep apnoea (SA) is ∼2 times more prevalent in men than women. However, this changes at menopause as the occurrence of SA increases and matches that of men. Menopause is a natural process, but it remains unclear why SA emerges only in a subpopulation of ageing women.

Accuracy of Consumer Grade Bioelectrical Impedance Analysis Devices Compared to Air Displacement Plethysmography [PDF]

open access: yes, 2011
The purpose of this study was to examine the accuracy of percent body fat estimates from seven different bioelectrical impedance analysis (BIA) models and a seven-site skin fold formula (SKF) compared with air displacement plethysmography (ADP) in ...

Ventilation inhomogeneity in patients with cystic fibrosis measured by electrical impedance tomography [PDF]

open access: yes, 2012
Objective: The distribution of ventilation within the lung is inhomogeneous. We hypothesized that the degree of inhomogeneity in patients with cystic fibrosis (CF) differs from that in healthy subjects.

Blood flow restriction exercise during microgravity exposure in parabolic flight

open access: yesExperimental Physiology, EarlyView.
Abstract This case report evaluates whether it is possible to perform blood flow restriction (BFR) exercise during exposure to microgravity. The objectives were three‐fold: (1) to determine if a personalised tourniquet system (PTS) hardware technology performs nominally and enables BFR exercise in microgravity; (2) to determine if BFR augments the ...

Elastic properties of arteries in hypertensive patients with hypertensive nephropathy and chronic stable angina

open access: yesPatologìâ, 2013
Arterial wall changes are one of the arterial hypertension (AH) earliest complications. Hypertensive nephropathy is the widespread complication of AH which makes a substantial contribution to end stage renal disease.

Segmental volume changes that occur in nonhuman primates during short term head up (HUT) and head down (HDT) tilt

open access: yesJournal of Electrical Bioimpedance, 2020
Nonhuman primates are often used in biomedical research and to investigate physiologic processes that occur in man. Impedance plethysmography was used to measure calf, thigh, pelvic, abdominal, and thoracic volume changes in ten Rhesus and eight squirrel

Body composition and nutritional habits in professional ballet dancers [PDF]

open access: yes, 2005
Object of this study was the analysis of fat mass (FM), fat free mass (FFM) and nutritional habits in professional ballet dancers. Our secondary aim was to evaluate daily energy intake and to compare nutritional habits with level of daily recommended ...

Human adaptation to high‐altitude: A contemporary comparison of the oxygen cascade in Andean, Tibetan and Ethiopian highlanders

open access: yesExperimental Physiology, EarlyView.
Abstract Human populations native to high altitude have evolved distinct physiological adaptations to chronic hypoxia. This adaptation is evident in the O2 transport cascade. In this review, with brief inclusion of the related genetic adaptations, we compare the O2 cascade across three well‐characterized high‐altitude populations: Andeans (Aymara and ...

Ouabain‐induced hypertension in rats: Mechanisms, variability and translational implications

open access: yesExperimental Physiology, EarlyView.
Abstract Ouabain‐induced hypertension is a multifactorial and condition‐dependent phenomenon involving coordinated actions across vascular, renal and central nervous system pathways. At the vascular level, ouabain inhibits Na⁺/K⁺‐ATPase, particularly the α2‐isoform, leading to elevated intracellular Ca2⁺, enhanced vasoconstriction and structural ...
