Experimental Physiology, EarlyView.Abstract Ageing is associated with cognitive decline and increased risk of developing neurodegenerative disease. Repeated passive heating, using hot water immersion (HWI), may improve cognitive performance via improved cerebral oxygenation, but this is yet to be examined in older adults.

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.

Experimental Physiology, EarlyView.Abstract Hypoxaemia occurs in intermittent forms, such as obstructive sleep apnoea, and in continuous forms, such as at high altitude, and is increasingly recognized as a modulator of cardiometabolic risk. Although hypoxaemia alters postprandial glucose and lipid metabolism, its effects on ketone bodies remain unclear.

Experimental Physiology, EarlyView.Abstract Intermittent apnoeas may induce hypoalgesia; however, the effects of low‐lung‐volume static apnoea have not been investigated. Eighty healthy participants were randomized to an apnoea group (AG) or a control group (CG). The AG performed a 6‐min protocol of intermittent static apnoea at low lung volume (passive exhalation), whereas the CG ...

The Journal of Physiology, EarlyView.Abstract figure legend Temporal scaling physiology differs significantly between mice and humans. Mice have higher metabolism, heart and respiratory rate, as well as faster blood flow rates, brain activity and physiological dynamics over time. These differences influence the temporal resolution needed in preclinical imaging of mouse models to ...

The Journal of Physiology, EarlyView.Abstract figure legend Participants completed cycling exercise with (placebo) and without (25 µg intrathecal fentanyl) intact group III/IV muscle afferent feedback in three settings: normoxia, acute hypoxia and chronic hypoxia after 7–9 days of acclimatisation (∼3800 m). Blocking afferent feedback suppressed exercise hyperpnoea across all environments,

CO2 chemoreflex contributions to ventilatory long‐term facilitation
The Journal of Physiology, EarlyView.Abstract figure legend To determine whether changes in CO2 chemoreflex sensitivity contribute to ventilatory long‐term facilitation (LTF), we tested the hypothesis that hypercapnic acute intermittent hypoxia (AIH) induces ventilatory LTF and enhances peripheral, but not central, chemoreceptor CO2 chemoreflex sensitivity.

NMR in Biomedicine, Volume 39, Issue 10, October 2026.This study combines segmented T1ρ preparation into a 3‐D gradient‐echo sequence for simultaneous quantitative susceptibility, T2*, and T1ρ mapping of infarcted mouse hearts ex vivo. The method enabled assessment of T1ρ and T2* relaxation time maps and magnetic susceptibility, with ischemic regions clearly identified by all contrasts and consistent with

Administration of phenylhydrazine to rabbits resulted in the denaturation of hemoglobins in erythrocytes, causing the formation of intracellular precipitates known as Heinz bodies, severe hemolytic anemia, and reticulocytosis.

NMR in Biomedicine, Volume 39, Issue 10, October 2026.Workflow (Steps 1–4): Both MBF and MOEF maps were registered to a T2‐weighted fat‐suppressed structural image using rigid or affine transformations in 3D Slicer. The gastrocnemius, soleus, and tibialis anterior muscles were segmented in 3D volumes, and the resulting segmentations were used as masks to propagate to all parameter maps to extract regional
