Effect of artificial gravity on calcaneal bone marrow adipose tissue and mineral content in female and male participants in 60 days of bed rest

Experimental Physiology, EarlyView.
Abstract Modulation of bone marrow adipose tissue (BMAT) with prolonged inactivity was reported in haemopoietic but not in non‐haemopoietic bones. This prospective randomized controlled trial submitted 16 men and 8 women to 60 days of 6° head‐down‐tilt bed rest.

Contributions of vascular ageing to late‐onset Alzheimer's disease

Experimental Physiology, EarlyView.
Abstract Late‐onset Alzheimer's disease (LOAD) is an age‐related disease that is strongly associated with vascular risk factors and cerebrovascular impairments. As such, changes in the vasculature with advancing age likely contribute to LOAD, but the mechanisms underlying these contributions remain incompletely understood.

Diagnostic methods, calculation parameters and gradations of extrinsic compression stenosis of the internal jugular veins

Вестник медицинского института «Реавиз»: Реабилитация, врач и здоровье
Background. Growing interest in external compressive stenosis of the internal jugular veins (IJV) stems from its proposed role in the pathogenesis of intracranial hypertension and cerebral venous dysfunction.

Carotid artery dissection linked to intermittent apnoeic swimming: A case–control study

Experimental Physiology, EarlyView.
Abstract Internal carotid artery (ICA) dissection is a rare and potentially devastating cause of cerebral ischaemia, initiated by an intimal tear or rupture of the vasa vasorum, that can lead to an intraluminal thrombus, vascular stenosis, occlusion, or dissecting aneurysm formation.

Angiography‐Negative Subarachnoid Hemorrhage Detected After Emergent Percutaneous Coronary Intervention for Non‐ST‐Segment Elevation Myocardial Infarction: A Case Report

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Neurological deterioration, headache, vomiting, bradycardia, or hypertension after emergent percutaneous coronary intervention should prompt immediate brain imaging. When subarachnoid hemorrhage is detected shortly after coronary stenting, the hemorrhage onset may remain uncertain, and antiplatelet decisions require individualized ...

Cerebral Blood Transit in Sickle Cell Anemia

Journal of Magnetic Resonance Imaging, Volume 64, Issue 3, Page 738-750, September 2026.
ABSTRACT Background Sickle cell anemia (SCA) patients upregulate cerebral blood flow to compensate for decreased arterial oxygen content. Such hyperemic conditions can manifest as venous hyperintense signal on arterial spin labeling (ASL) MRI, which may reflect faster capillary blood transit, altered oxygen extraction fraction (OEF), and infarct risk ...
