Acute Cervical Vagus Nerve Stimulation Modulates Gastric Slow Waves in the Distal Rat Stomach

open access: yesNeurogastroenterology &Motility, EarlyView.
Slow waves were mapped on the rat gastric serosa during acute cervical vagus nerve stimulation with three stimulation protocols. The medium and high cVNS protocols modified slow wave frequency, and slow wave propagation was temporarily disrupted during stimulation in all subjects.

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

open access: yesExperimental 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.

Heart rate response to transient hypoxia in patients with heart failure and Cheyne–Stokes respiration

open access: yesExperimental Physiology, Volume 110, Issue 4, Page 532-542, 1 April 2025.
Abstract Cheyne–Stokes respiration (CSR), a rhythmic rise and fall in ventilation often experienced by patients with heart failure during sleep, is typically accompanied by an oscillation in heart rate (HR) at the same frequency. The mechanisms responsible for this oscillation are still debated.
