A comparison of normobaric and hypobaric hypoxia effects on cerebrovascular response pre and post maximal exercise

Experimental Physiology, EarlyView.
Abstract A lack of consensus remains on whether normobaric hypoxia (NH) and hypobaric hypoxia (HH) may differentially impact physiological factors affecting cerebrovascular regulation, particularly with an additional strenuous exercise component. We sought to compare the acute effects of NH and HH on global cerebral blood flow (gCBF) at an altitude ...

Macro‐ and microcirculatory factors affecting foot temperature change during walking

Experimental Physiology, EarlyView.
Abstract Change in skin temperature is a complex process affected by several factors. During walking, increased microcirculatory activity, such as muscle metabolism, could increase foot temperature. The ensuing macrocirculatory responses, such as increased leg blood flow (LBF), might also increase foot temperature.

Physiological mechanisms underlying enhanced performance with blood flow restriction training: neuromuscular, vascular and metabolic adaptations

The Journal of Physiology, EarlyView.
Abstract figure legend We investigated how 6 weeks of dynamic knee‐extensor interval training with blood flow restriction (BFR‐leg) and without (CTRL‐leg) impacts performance and its mechanisms using non‐invasive methods. Specifically, we used gold‐standard methods to assess neuromuscular function, vascular function using Doppler ultrasound, and near ...

Role of reactive oxygen species in mediating peripheral hypoxic vasodilation and sympathoexcitation at high altitude

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude acclimatisation increases muscle sympathetic nerve activity (MSNA) via activation of the arterial chemoreflex, pulmonary arterial baroreceptors and resetting of the sympathetic vascular baroreflex. However attempting to silence these mechanisms only partially normalises MSNA, implicating other contributory ...

Matrix‐Activated Aptamer Sensors for Human Serum Analysis

Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.
The sample self‐analyzes: The predominant serum proteins, albumin and immunoglobulin G, were leveraged to activate the response of fluorescent aptamer probes within the biological matrix. The fluorescence‐anisotropy‐based sensing platform demonstrated both performance and consistency for the direct detection of small molecules in serum‐rich samples ...
