Flexible parental care in a songbird correlates with sex‐specific responses to seasonal phenology, mating opportunity and reproductive success

Journal of Animal Ecology, EarlyView.
This population‐comparative study reveals that male and female parents respond differently to social and ecological conditions. This sex‐specific responsive strategy is related to the incongruent parental care systems across populations in Chinese penduline tits.

Hormone Replacement Therapy Uptake and Discontinuation Trends From 1996‐2023: An Observational Study of the Welsh Population

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Objective To analyse prescribing trends for oral and transdermal hormone replacement therapy (HRT) in Wales from 1996 to 2023, including predictors of discontinuation within one year of initiation. Design Observational study using the Secure Anonymised Information Linkage (SAIL) databank.

Risk of Cancer With Hormone Replacement Therapy: A Narrative Review

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Hormone replacement therapy (HRT) remains the cornerstone of menopausal symptom management, effectively alleviating vasomotor symptoms and genitourinary syndrome, whilst mitigating long‐term risks such as osteoporosis. However, despite an increasing body of evidence on the relative safety of HRT, earlier studies that demonstrated an increased ...

Microbial and Metabolic Correlates of Endometrial Dysfunction in Polycystic Ovary Syndrome: A Translational Study

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Objective Women with polycystic ovary syndrome (PCOS) exhibit a substantially increased risk of miscarriage, yet the underlying mechanisms remain inadequately understood. This study aimed to investigate whether specific gut microbial dysbiosis and metabolic disturbance are associated with and may potentially contribute to endometrial ...

Effect of Social Rank on Gut Microbes and Their Metabolites of Greater Long‐Tailed Hamsters (Tscherskia triton)

Integrative Zoology, EarlyView.
Social rank in greater long‐tailed hamsters (Tscherskia triton) shapes gut microbiota composition and metabolite profiles. Dominant males exhibit a “high‐vigilance, metabolically activated” phenotype, with elevated aggression and specific gut microbiota enriched in energy‐harvesting taxa and fecal queuine.

Gonadal Development–Related Genes and a Male‐Specific Genetic Marker Identified in the Endangered Sichuan Taimen (Hucho bleekeri)

Integrative Zoology, EarlyView.
Integrated transcriptomic and proteomic analyses were used to validate gonadal development–related genes and to identify a sex‐specific molecular marker in Hucho bleekeri. ABSTRACT Sex determination and differentiation represent fundamental topics in reproductive biology. Sichuan taimen (Hucho bleekeri), a first‐class national protected fish species in

Saving Water to Survive: Alternative Water Loss Strategies Could Explain Color Polymorphism Maintenance in a Lacertid Lizard

Integrative Zoology, EarlyView.
We demonstrate that red male Podarcis muralis exhibit higher evaporative water loss compared to other morphs, indicating a physiological strategy that prioritizes hydroregulation over fine thermoregulation. This suggests red morphs are adapted to cooler, wetter niches, while white and yellow morphs possess superior water conservation mechanisms to ...

What anabolic–androgenic steroids reveal about the limits of current harm reduction models

Addiction, EarlyView.
Abstract Background Harm reduction has largely been shaped by responses to psychoactive drug use where the most urgent harms are acute. These models focus on overdose, blood‐borne viruses, and rapid‐onset toxicity related harms. When applied wholesale to anabolic–androgenic steroids (AAS), they obscure the distinctive pharmacology, consumer typologies,

Postcode‐Level Variation and Environmental Determinants of Respiratory Allergies in a Large German Cohort

Allergy, EarlyView.
Young children (0–9 years) and residents of urban areas appeared particularly vulnerable to respiratory allergy development and exacerbation. Incidence showed nonlinear associations with PM10, PM2.5, temperature, and alder/birch pollen, while DPMR showed similar patterns, except for NO2 and the interaction O3*NO2.

Testicular histopathology and its association with germ cell numbers, serum concentrations of reproductive hormones, and semen quality

Andrology, EarlyView.
Abstract Background It is well‐established that spermatogenesis, semen quality, and reproductive hormones are interlinked. It is, however, less well‐described how various specific testicular histopathologies are linked to reproductive hormones and semen quality.
