Environmental Toxicology, EarlyView.ABSTRACT Metal contamination in aquatic ecosystems poses substantial risks to freshwater organisms, with mixture effects often deviating from predictions based on single‐metal toxicity. Understanding how age‐specific sensitivities and multiple exposure pathways influence mixture effects is critical for accurate risk assessment.

Reproductive Challenges of the Ageing Female: A Comprehensive Narrative Review
BJOG: 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.

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 ...

Fertilization failure and oocyte activation.
The journal of medical investigation : JMI, 2000 Recent reports have suggested that when unfertilized oocytes with a spermatozoon after intracytoplasmic sperm injection (ICSI) are properly activated, the activated oocytes develop normally similar to fertilized oocytes. However, human oocytes do not easily respond to universal activators of mammalian oocytes like ethanol or calcium ionophore A23187 ...

Iflaviruses in arthropods: when small is mighty
Insect Science, EarlyView.Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Calcitonin‐like diuretic hormone influences reproduction in adult female Rhodnius prolixus
Insect Science, EarlyView.Highlights • CT/DH‐like immunoreactivity is present in female reproductive tissues • CT/DH receptor transcripts are expressed in the fat body and ovaries • RNAi knockdown of CT/DH receptors reduces egg number and hatching rate • Rhopr‐CT/DH increases RhoprVg1 and RhoprVgR expression in ovaries in vitro • Rhopr‐CT/DH stimulates oviduct contractions in a
