Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI
Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...

Optimizing cerebrovascular endothelial health through shear stress modulation
Abstract The endothelium plays a pivotal role in regulating cerebrovascular blood flow, and its dysfunction increases the risk of cerebrovascular disease. Endothelial shear stress, a primary mechanical stimulus for endothelial nitric oxide production, is a key modulator of vascular adaptation.

Abstract Dynamic resistance exercise (RE) produces sinusoidal fluctuations in blood pressure that are mirrored by middle cerebral artery blood velocity (MCAv). However, whether lower‐ or upper‐body RE elicits a differential cerebrovascular response has not yet been examined.

Abstract figure legend Human skin contains several classes of mechanoreceptive afferents that encode mechanical stimulation. For example, C‑tactile (CT) afferents are suggested to signal the pleasant aspects of gentle touch and are activated effectively by slow brushing of hairy skin.

Gas exchange and pulmonary stress variations during SCUBA and breath‐hold diving in open seawater
Abstract figure legend Healthy, trained divers were studied before, during and after diving in open seawater with different techniques. SCUBA divers (diving to 15 or 40 m with air; cycling at depth) and breath‐hold divers (BHDs; sled‐assisted dives to 15, 25 or 40 m) underwent underwater and surface arterial blood gas (ABG) sampling.

Abstract figure legend Schematic overview of the 5 day lower‐limb motor skill learning protocol combining ankle visuomotor practice with transcranial direct current stimulation (tDCS). Participants were allocated to motor skill practice with active tDCS over the leg representation of primary motor cortex (SKILL‐STIM), motor skill practice with sham ...

ABSTRACT Introduction/Aims Combined central and peripheral demyelination (CCPD) is a rare dysimmune disorder sharing features with multiple sclerosis (MS) and chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). Direct comparisons of central and peripheral diagnostic findings across these entities remain limited. We, therefore, performed a

Fast 23Na MRI of the human calf at 7T was achieved by reducing nominal spatial resolution. Shorter measurement times can improve clinical feasibility of 23Na MRI while preserving reliable quantification of apparent tissue sodium concentration through partial volume, relaxation, and B0/B1 corrections.

Loxomerus antipodes Liebherr and Marris, sp. nov. (Coleoptera: Carabidae), is described from the New Zealand subantarctic Antipodes Islands archipelago. Loxomerus antipodes, sp. nov., was considered conspecific with Loxomerus brevis Blanchard, 1853, from the Auckland Islands, but it is diagnosed from that sister taxon based on numerous anatomical ...
