American Journal of Human Biology, Volume 38, Issue 4, April 2026.ABSTRACT Type 1/M1/TH1 and type 3/M1/TH17 pro‐inflammatory switches are risks for latent Mycobacterium tuberculosis (Mtb) reactivation and ongoing infection transmission. This paper considers the heavy toll of reactivation risk in Indigenous communities in Canada and the chronic, everyday pro‐inflammatory stressors connected with type 3/M1/TH17 immune ...

Birth Defects Research, Volume 118, Issue 4, April 2026.ABSTRACT Background Animal models remain essential for understanding developmental toxicology, providing insights into how in utero exposures affect fetal and placental outcomes. Litter‐bearing species are widely used due to their efficiency and reproducibility, but conventional approaches often summarize outcomes at the litter level, masking ...

Clinical Case Reports, Volume 14, Issue 4, April 2026.ABSTRACT Transvaginal ultrasound‐guided oocyte retrieval is routine for assisted reproduction, but unfit for some special patients. We report an elderly infertile patient with adenomyosis, whose transvaginal retrieval was high risk. Intraoperative conversion to transabdominal retrieval succeeded safely.

Rebreeding of Female Mountain Lions After Litter Mortality
Ecology and Evolution, Volume 16, Issue 4, April 2026.We documented rapid rebreeding by female mountain lions (Puma concolor) following litter loss, including the shortest known rebreeding interval to date. These observations highlight the importance of infanticide and intraguild competition in shaping female fitness and population dynamics.

Wolf Presence Disrupts Seasonal Variation in Hair Cortisol Among Free‐Ranging Beef Cattle
Ecology and Evolution, Volume 16, Issue 4, April 2026.Predators exert indirect effects on prey populations beyond direct predation, but how predator reintroduction restructures prey physiology remains poorly understood. Using hair cortisol analysis in cattle exposed versus unexposed to wolves, we found that wolf presence disrupted normal seasonal cortisol regulation patterns.

The Effects of Menstrual Cycle Phase on Gastrointestinal Responses to a Simulated Football Match
European Journal of Sport Science, Volume 26, Issue 4, April 2026.ABSTRACT This study evaluated the effects of a simulated football match on gastrointestinal (GI) symptoms, damage and indirect markers of gut barrier integrity, and investigated whether GI responses are modulated by menstrual cycle (MC) phase. Twelve eumenorrheic females completed two 45‐min bouts of an intermittent treadmill protocol, replicating the ...
