Elevational variation in heart mass and suppression of hypoxia‐induced right ventricle hypertrophy in Andean leaf‐eared mice (Phyllotis)

The Journal of Physiology, EarlyView.
Abstract figure legend In lowland mammals that ascend to high elevation, hypoxia‐induced changes in the pulmonary circulation can give rise to hypoxic pulmonary hypertension (HPH) and associated right‐ventricle (RV) hypertrophy. Andean mice with broad elevational ranges have greater heart mass relative to body size at higher elevations, but they ...

Mechanisms underlying increased nest predation in natural gas fields: a test of the mesopredator release hypothesis

Ecosphere, 2019
Anthropogenic activities are changing landscapes and the context in which predator–prey dynamics evolved, thereby altering key ecological processes and community structure. Yet, the specific mechanisms underlying such changes are rarely understood.

Mitochondrial physiology in cardiac muscle of deer mice native to high altitude

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude deer mice exhibited evolved changes in mitochondrial energy metabolism and reactive oxygen species (ROS) management that may support cardiac performance under cold hypoxic conditions. High‐altitude mice had increased activity of lactate dehydrogenase (LDH) in the heart, probably enhancing the capacity for lactate ...

Scrapie versus Chronic Wasting Disease in White-Tailed Deer

Emerging Infectious Diseases
White-tailed deer are susceptible to scrapie (WTD scrapie) after oronasal inoculation with the classical scrapie agent from sheep. Deer affected by WTD scrapie are difficult to differentiate from deer infected with chronic wasting disease (CWD).

Novel Focus of Sin Nombre Virus in Peromyscus eremicus Mice, Death Valley National Park, California, USA

Emerging Infectious Diseases, 2018
The deer mouse (Peromyscus maniculatus) is the primary reservoir for Sin Nombre virus (SNV) in the western United States. Rodent surveillance for hantavirus in Death Valley National Park, California, USA, revealed cactus mice (P.

The influence of haemoglobin–O2 affinity on aerobic capacity in hypoxia in high‐altitude deer mice (Peromyscus maniculatus)

The Journal of Physiology, EarlyView.
Abstract figure legend The influence of haemoglobin–O2 affinity on aerobic capacity in hypoxia has been contentious. Many high‐altitude natives have greater haemoglobin–O2 affinity (lower P50, the O2 pressure at 50% haemoglobin saturation) than their low‐altitude counterparts, but the advantages of this change for aerobic metabolism have often remained

Ventilatory and heart rate responses to hypoxia in pre‐ and post‐menopausal ethnically Tibetan women residing at ∼3800 m in Mustang, Nepal

The Journal of Physiology, EarlyView.
Abstract figure legend Tibetan women livingat high altitude exhibit distinct physiological traits that can enhance oxygen transport in chronic hypoxia. Menopausal status influences cardiopulmonary responses to hypoxia in women living at low altitudes.

The Astrocyte Clock Controls Circadian Perineuronal Net Remodeling, Synapse Strength and Learning Behavior

Glia, Volume 74, Issue 10, October 2026.
Bmal1 regulates astrocyte extracellular matrix (ECM) gene expression. Bmal1 deletion in astrocytes disrupts normal circadian rhythms in perineuronal nets (PNN) and reduces PNN content in the hippocampus. In parallel with loss of PNNs, deletion of the core circadian clock gene Bmal1 in astrocytes alters behavior and synaptic function in vivo.

ACE‐inhibitory peptide Leu‐Tyr‐Ala in skeletal muscle actin exhibits anti‐aging effects through the inhibition of acn‐1 in Caenorhabditis elegans

Journal of the Science of Food and Agriculture, Volume 106, Issue 12, Page 7002-7014, September 2026.
Abstract BACKGROUND Inhibitors of angiotensin‐converting enzyme (ACE) are used in pharmaceuticals and functional foods. Captopril, a well‐known ACE inhibitor, extends the lifespan of the nematode Caenorhabditis elegans. Bioactive peptides derived from food sources are considered safe ACE inhibitors.

The Changing Landscape of Hantavirus Infections: A Narrative Review of Epidemiology, Pathogenesis, and Countermeasures

Reviews in Medical Virology, Volume 36, Issue 5, September 2026.
ABSTRACT Hantaviruses are emerging zoonotic pathogens of increasing global public health significance. Their epidemiological landscape is rapidly changing due to ecological disruption, climate variability, urbanisation, and evolving human–animal interfaces.
