The Murine Cl-/HCO3- Exchanger Ae3 (Slc4a3) is Not Required for Acid-Base Balance but is Involved in Magnesium Handling by the Kidney

Cellular Physiology and Biochemistry, 2014
Background: The Slc4 family of bicarbonate transporters consists of several members, many of which are highly expressed in the kidney and play an important role in acid-base homeostasis. Among them are Ae1 (Slc4a1) and Ae2 (Slc4a2).

Increases in skin perfusion and blood oxygen in the non‐exercising human limbs during exercise in the heat: Implications for control of circulation

Experimental Physiology, EarlyView.
Abstract Blood flow in the inactive limb tissues and skin is widely thought to decline during incremental exercise to exhaustion due to augmented sympathoadrenal vasoconstrictor activity, but direct evidence to support this view is lacking. Here, we investigated the inactive‐forearm haemodynamic (Q̇forearm${\dot{Q}}_{\mathrm{forearm}}$) and oxygenation

Intermittent hand and forearm immersion in 20°C water attenuates thermal, cardiovascular, and perceptual strain in older adults during heat stress

Experimental Physiology, EarlyView.
Abstract Adults >65 years of age experience deleterious health effects during extreme heat events at a greater rate than any other age cohort. The purpose of this study was to identify the effectiveness of acute intermittent hand and forearm (H+F) water immersion and/or chronic (7 week) folic acid supplementation on reducing thermal and cardiovascular ...

Quantifying skin microvascular function responses to distinct forms of heat stress in humans using optical coherence tomography

Experimental Physiology, EarlyView.
Abstract Optical coherence tomography (OCT) enables visualization and quantification of the cutaneous microvasculature, yet no study has compared responses to distinct forms of heating in humans. We hypothesized that local skin heating (LH) would evoke larger responses in microvascular diameter, velocity, flow and density than passive whole‐body ...

New Metrics for Evaluating Viral Respiratory Pathogenesis.

PLoS ONE, 2015
Viral pathogenesis studies in mice have relied on markers of severe systemic disease, rather than clinically relevant measures, to evaluate respiratory virus infection; thus confounding connections to human disease.

Breathing irregularities and postnatal hypoxaemia in an experimental model of essential hypertension

The Journal of Physiology, EarlyView.
Abstract figure legend Neonatal spontaneously hypertensive rats (SHRs) exhibit inherent respiratory dysfunction in early life, including oscillatory breathing patterns and apnoeic events that cause oxygen desaturation and brain hypoxia, in addition to an impaired hypoxic ventilatory response.

Cardiovascular and respiratory changes during slow-wave sleep in rats are associated with electrocorticogram desynchronization

Brazilian Journal of Medical and Biological Research, 1997
In awake rats a single recurrent larger tidal volume (deep breaths) occurs at regular intervals, followed by oscillations in arterial pressure and heart rate.

Defining Healthy Weight Loss and Target Weight in the Era of Highly Effective Treatment of Patients With Obesity

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 4, August 2026.
ABSTRACT Background Highly effective anti‐obesity medications (AOMs) induce substantial weight loss and have renewed debate on appropriate treatment targets. Weight loss comprises reductions in fat mass (FM) and fat‐free mass (FFM), with skeletal muscle (SM) as the major component of FFM.

A Simple Measure to Assess Hyperinflation and Air Trapping: 1-Forced Expiratory Volume in Three Second / Forced Vital Capacity

Balkan Medical Journal, 2017
Background: Several recent studies have suggested that 1 minus-forced expiratory volume expired in 3 seconds / forced vital capacity (1-FEV3/FVC) may be an indicator of distal airway obstruction and a promising measure to evaluate small airways ...
