Conservation Management Strategies Shape Glucocorticoid Levels in African Elephant Populations More Than Parasite Load

Journal of Zoology, EarlyView.
Understanding the factors influencing physiological stress is essential for interpreting how wildlife responds to contrasting environmental and management conditions. Across 19 South African elephant populations, we found that smaller reserves, self‐drive tourism, and high elephant density under low vegetation productivity were associated with elevated

Of mice and men—The emerging oral–gut–brain axis of health and disease

Periodontology 2000, EarlyView.
Abstract Objectives Oral health's inextricable links to systemic health are highlighted by the emerging oral–gut–brain axis and other well‐known axes. There is growing evidence of a complex oral–gut–brain axis linking mouth and gut microbiomes with the central nervous system.

Confined spaces in space: Cerebral implications of chronic elevations of inspired carbon dioxide and implications for long‐duration space travel

Experimental Physiology, EarlyView.
Abstract Cerebrovascular regulation is critically dependent upon the arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_{\mathrm{2}}}}}$), owing to its effect on cerebral blood flow, tissue PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_{\mathrm{2}}}}}$, tissue proton concentration, cerebral metabolism and cognitive and neuronal ...

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

The Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

Abcc1 deficiency protects from corticosterone but not cortisol‐induced adiposity and insulin resistance in a sex‐specific manner

The Journal of Physiology, EarlyView.
Abstract figure legend A mouse model of exogenous glucocorticoid (GC) treatment was used to determine (1) if corticosterone induced the same metabolic dysregulation as cortisol, and (2) whether these differences were mediated by the corticosterone‐specific transmembrane exporter Abcc1.

Thyroid antibody positivity in pregnancy is associated with altered reproductive hormone concentrations and placental growth in Lewis rats

The Journal of Physiology, EarlyView.
Abstract figure legend Thyroid antibody positivity (TAb+) in pregnancy is associated with adverse pregnancy outcomes, but the mechanisms are unclear. This study developed a rodent model of TAb+ in pregnancy, induced prior to mating so that TAb+ exposure occurred throughout the pregnancy. TAb+ did not alter thyroid hormone concentrations and had minimal

Decadal Bowhead Whale Baleen Stable Isotope and Hormone Chronologies (1985–2010) Provide Insight Into Arctic Ecosystem Change

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
Long‐term chronologies constructed from individual bowhead baleen plates reveal stable isotope declines consistent with regional Arctic food web or productivity changes superimposed on global anthropogenic C and N inputs, while relatively stable hormone concentrations over the same period provide no evidence of a concomitant increase in physiological ...

The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome

Biological Reviews, Volume 101, Issue 4, Page 1877-1903, August 2026.
ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

Design, Synthesis, and Biological Evaluation of Chiral Urea and Thiourea Derivatives as Multitarget‐Directed Anti‐Alzheimer Agents

Drug Development Research, Volume 87, Issue 5, August 2026.
ABSTRACT A series of novel chiral urea and thiourea compounds were designed as multitarget‐directed ligands for Alzheimer's disease and evaluated against hAChE, hBChE, and hMAO‐B, with exploratory assessment of HSD10. These chiral compounds were synthesized and fully characterized, and their enantiopurity was confirmed via HPLC.
