Bisphenols and Phthalates in Bottled Mineral Water: First Evidence of Co‐Occurrence, Estrogenic Activity, and Health Risk in Brazil

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA), its structural analogs, and phthalates are synthetic chemicals widely used, with documented endocrine‐disrupting activity. This study aimed to develop and validate a selective multiresidue analytical method for the simultaneous determination of BPA, 10 bisphenol analogs, and six phthalates in PET‐bottled mineral water.

Synergistic Toxicity of Low‐Concentration Metal Mixture on Male Rats: Reproductive, Renal, and Hepatic Effects

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Mining plays a crucial role in economic development, but improper management can lead to severe environmental degradation. Particularly for iron ore, mining generates vast amounts of tailings often stored in unstable dams. This study aims to investigate the toxicological impacts of environmentally relevant concentrations of metals mixture ...

Factors associated with the reproductive performance of ewes inseminated laparoscopically in England and Wales: A longitudinal study

open access: yesVeterinary Record, EarlyView.
Abstract Background Laparoscopic intrauterine artificial insemination (Lap‐AI) is used in sheep genetic improvement programmes. However, the lambing rate (LR) (i.e., the proportion of inseminated ewes that lamb) following Lap‐AI is variable. Previously, one small UK study investigated factors associated with LR, but it did not adjust for dependencies ...

Spider mite genotypes with higher growth rate suffer more from competition but exert stronger reproductive interference

open access: yesJournal of Animal Ecology, EarlyView.
Genetic correlations have strong implications for species coexistence and their evolution. Studies addressing this issue generally tackle traits associated with competition for food and those underlying reproductive interference separately, whereas it is clear that the interaction among these is key to understand the ecology and evolution of closely ...

Reproductive Challenges of the Ageing Female: A Comprehensive Narrative Review

open access: yesBJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Changes in societal norms over the last few decades have resulted in novel family planning trends, notably delayed childbearing and increased maternal age at the birth of the first child. Despite advances in reproductive medicine, ageing poses significant challenges.
