50% body weight loading reduces stature increases and lumbar disc expansion from 4 h hyper‐buoyancy floatation versus 15 min sitting upright

Experimental Physiology, EarlyView.
Abstract Microgravity is associated with stature increases, back pain and post‐flight intervertebral disc (IVD) herniation. This study aims to determine whether 30 s seated 50% body weight (BW) axial loading is comparable to 15 min sitting upright in 1 g upon changes in stature, anterior lumbar IVD height (via ultrasound), passive vertebral stiffness ...

An experimentally informed computational model of neurovestibular adaptation to altered gravity

Experimental Physiology, EarlyView.
Abstract Transitions to altered gravity environments result in acute sensorimotor impairment for astronauts, leading to serious mission and safety risks in the crucial first moments in a new setting. Our understanding of the time course and severity of impairment in the early stages of adaptation remains limited and confounded by unmonitored head ...

Time‐course analysis of cerebral circulation and cardiorespiratory responses to acute central blood volume reduction in healthy young males

Experimental Physiology, EarlyView.
Abstract Central blood volume (CBV) reduction challenges circulatory and respiratory homeostasis, particularly during the initial compensatory phase (0–2 min), when rapid physiological adaptations occur. In this study, we examined dynamic cardiorespiratory responses to CBV reduction using lower‐body negative pressure (LBNP) in 11 healthy young males ...

An age‐associated decline in the role of the sarcoplasmic reticulum and associated calcium‐handling proteins sets the pace for sinoatrial node function

The Journal of Physiology, EarlyView.
Abstract figure legend Stable, responsive pacemaking in the sinoatrial node is driven by the activity of the funny current (membrane clock), interplay of calcium cycling and release from the sarcoendoplasmic reticulum with depolarising sodium‐calcium exchange current (calcium clock). With increasing age, key proteins associated with calcium cycling are

Presentation of preload and afterload to isolated heart preparations

The Journal of Physiology, EarlyView.
Abstract figure legend The heart can be isolated, and when this is so, it must be subjected to loading conditions. Over the past few decades, various loading methods have been developed to prescribe preload and afterload to isolated working‐heart preparations.

Endoscopic Visualization of a Jejuno‐Colonic Fistula in a Case of Monomorphic Epitheliotropic Intestinal T‐Cell Lymphoma

DEN Open, Volume 7, Issue 1, April 2027.
Monomorphic epitheliotropic intestinal T‐cell lymphoma (MEITL) rarely presents with gastrointestinal fistula formation. A rare case of MEITL is identified in an elderly woman with marked weight loss and hypoalbuminemia, in whom a jejunocolic fistula is directly visualized endoscopically.
