Cerebrovascular flow‐mediated dilation in humans: Methodological challenges, physiological interpretation and future integrations

Experimental Physiology, EarlyView.
Abstract Arterial shear‐mediated vasodilation is a well‐established measure of endothelial function and serves as a critical biomarker for cardiovascular disease risk. Endothelial function can be measured using a variety of experimental methodologies; however, the most widely adopted technique is ultrasound‐based flow‐mediated dilation (FMD), in which ...

Brain strain: Blood flow and metabolism in environmental extremes

Experimental Physiology, EarlyView.
Abstract This narrative review compares and contrasts the most commonly encountered environmental stressors on human cerebrovascular functioning. From high altitude and space, extreme apnoea, heat and cold stress, the impact of these stressors on the regulation of cerebral blood flow (CBF) and oxygen metabolism (CMRO2${\mathrm{CM}}{{\mathrm{R}}_ ...

Is resting muscle sympathetic nerve activity related to peripheral or cerebrovascular haemodynamics at high altitude? A retrospective analysis

Experimental Physiology, EarlyView.
Abstract High‐altitude hypoxia elicits several profound physiological responses, including substantial increases in muscle sympathetic nerve activity (MSNA); however, the association of this heightened MSNA with cardiovascular and cerebrovascular haemodynamics remains unclear in lowlanders and indigenous highlander populations.

Effects of nocturnal periodic breathing on sympathetic nerve activity and ventilatory control at high altitude: a randomised, crossover study

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of the randomised crossover study investigating the effects of nocturnal periodic breathing (nPB) on sympathetic activity and ventilatory acclimatisation in hypobaric hypoxia equivalent to 4000 m altitude. Participants completed two 3‐day sojourns where nPB was inhibited by increasing inspiratory CO2 fraction ...

Beyond Total Content: Assessing the Bioaccessibility of Metals in Tattoo Inks Using Validated Extraction Media

Analytical Science Advances, Volume 7, Issue 2, December 2026.
ABSTRACT A validated analytical workflow is presented for determining total and bioaccessible concentrations of regulated elements in tattoo inks, addressing the lack of harmonized protocols for comparing extraction approaches in complex matrices. Although current legislation defines limits for soluble fractions of selected metals, it does not specify ...

Beyond institutional silence: How social representations and psychological capital shape police responses to femicide in Brazil

Analyses of Social Issues and Public Policy, Volume 26, Issue 3, December 2026.
Abstract This study investigates how social representations, organizational silence, and psychological capital (PsyCap) interact to shape police responses to femicide within the Civil Police of Bahia, Brazil. A qualitative approach was adopted, based on 32 semi‐structured interviews with civil police officers and the analysis of 286 institutional ...

Bacterial sialidases subvert the complement system through desialylation

Protein Science, Volume 35, Issue 11, November 2026.
Abstract Bacterial sialidases (neuraminidases) are widely studied virulence factors, yet their impact on the complement system, a central component of innate immunity, remains poorly understood. Here, we investigate the effects of six sialidases from five human pathogens, including Bacteroides fragilis, Clostridium perfringens, Tannerella forsythia ...

Sugammadex interference with serum progesterone measurement: an in‐vitro study

Anaesthesia, Volume 81, Issue 11, Page 1489-1496, November 2026.
Summary Introduction Sugammadex may interfere with serum progesterone immunoassays, potentially rendering measured concentrations and resulting recommendations unreliable. Methods We investigated the effect of a range of sugammadex concentrations on serum progesterone concentrations in samples from pre‐menopausal female volunteers.
