Peripheral chemoreflex restrains skeletal muscle blood flow during exercise in participants with treated hypertension

The Journal of Physiology, EarlyView.
Abstract figure legend Cardiorespiratory and brachial artery haemodynamic assessments were made during intravenous infusion of low‐dose dopamine, to inhibit the peripheral chemoreflex, and saline (control) at rest, and during hypoxia and rhythmic handgrip exercise in people with hypertension.

Regional cerebral perfusion and sympathetic activation during exercise in hypoxia and hypercapnia: preliminary insight into ‘Cushing's mechanism’

The Journal of Physiology, EarlyView.
Abstract figure legend During handgrip exercise in hypoxia, brain perfusion is suboptimal and muscle sympathetic nerve activity is potentiated (left panel). During the exercise in hypercapnia, brain perfusion is supraoptimal and muscle sympathetic nerve activity is suppressed (right panel). These observations support the notion that Cushing's mechanism

Acute intermittent hypercapnic hypoxia augments left ventricular contractility

The Journal of Physiology, EarlyView.
Abstract figure legend Twenty‐four healthy adults were studied to determine the effects of an acute session of 40 min of intermittent hypercapnic hypoxia on cardiac performance. Cardiac function was assessed via echocardiography at rest and during graded stages of lower‐body negative pressure before and after the intervention to quantify load ...

Pulmonary arterial mechanoreceptors modulate exercise‐induced sympathetic activation in healthy humans during moderate‐intensity hypoxic exercise

The Journal of Physiology, EarlyView.
Abstract figure legend This randomized cross‐over trial (N = 12) addressed the hypothesis that selective reduction of pulmonary arterial pressure (i.e. manipulation of pulmonary arterial mechanoreceptor activation) during hypoxic exercise would reduce sympathetic outflow (muscle sympathetic nerve activity (MSNA)) in healthy humans.

Cardiovascular outcome in 12‐month‐old male and female offspring of metformin‐treated obese mice

The Journal of Physiology, EarlyView.
Abstract figure legend This study described the effects of exposure to maternal obesogenic diet and metformin treatment during pregnancy on offspring cardiovascular outcomes. Maternal diet‐induced obesity and glucose intolerance led to predominantly vascular and cardiac abnormalities in 12‐month‐old female and male offspring, respectively.

Current progress of digital twin construction using medical imaging

Journal of Applied Clinical Medical Physics, Volume 26, Issue 9, September 2025.
Abstract Medical imaging is fundamental to digital twin technology, enabling patient‐specific virtual models of anatomy and physiology. By integrating high‐resolution modalities (Magnetic Resonance Imaging (MRI), Computed Tomography (CT), Positron Emission Tomography (PET), ultrasound) with computational frameworks, recent imaging advances now support ...

Mycoplasma pneumoniae Infection and Progressive Cold Agglutinin Syndrome in a Child: Catastrophic Multiple Cutaneous Necrosis

Clinical Case Reports, Volume 13, Issue 9, September 2025.
ABSTRACT Acrocyanosis and gangrene are rare but serious manifestations of CAS caused by MP infection in children. These symptoms may lead to severe complications if not managed appropriately, highlighting the need for clinicians to remain vigilant and provide proper supportive care.
