Evaluation of Potential Hormonal Activities of Ashwagandha (Withania somnifera)

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Ashwagandha is a widely used herb in traditional medicine systems, particularly Ayurveda. Despite its extensive tradition, growing concerns regarding its potential endocrinological effects have prompted scientific scrutiny. This review systematically evaluates the current preclinical, clinical, and case study evidence concerning AS's effects ...

Diving Deeper Into Mechanisms of Acrylamide‐Induced Toxicity: RNA Sequencing Reveals Transcriptomic Alteration and Retrotransposon Expression in Drosophila melanogaster

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Given the inevitability of human and animal exposure to acrylamide, there is increasing concern regarding its potential health risks. While a number of molecular mechanisms have been proposed, the complexity of acrylamide toxicological pathways and interactions remains incompletely characterized.

Assessment of Oxidative Stress, Vitellogenin, and Human Health Risks Derived From Nile Tilapia Exposed to Metals and Metalloids in Southeastern Brazil

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Urban coastal lagoons are highly vulnerable ecosystems increasingly affected by metal contamination, as well as multiple anthropogenic stressors. This study evaluated ecotoxicological and human health risks associated with chronic metal exposure in Nile tilapia (Oreochromis niloticus) from an anthropogenically impacted lagoon in southeastern ...

Staging concept for aging management: Definition, mechanism, and coping strategies

open access: yesVIEW, EarlyView.
We divided the overall aging stage into “pre‐aging”, “aging compensation”, and “aging disability”. For each stage, we delineate the clinical presentations, biological phenomena, theoretical underpinnings, and key management priorities. Abstract Aging, as a gradual and largely irreversible biological process, characterized by declining organismal ...

Sex Hormones and the Risk of Nasal Polyps: A Two‐Sample Mendelian Randomization Study

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective The pathophysiological roles of sex hormones in airway inflammation have drawn much attention recently. We aimed to explore the causal effect of sex hormones on chronic rhinosinusitis (CRS) and nasal polyps (NP) via a Mendelian randomization (MR) study.

Quantification of steroid hormones in free‐ranging Apennine wolf Canis lupus italicus hair samples collected post‐mortem

open access: yesWildlife Biology, EarlyView.
After decades of dramatic reductions in their populations, Italian wolves have begun recolonizing parts of their historic range. This growth in populations can lead to potential conflicts with human activities, which remain the main cause of wolf mortality.

First Non‐Invasive Monitoring of Fecal Steroids in Greater Caribbean Manatees (Trichechus manatus manatus)

open access: yesZoo Biology, EarlyView.
This study established the first fecal hormonal reference values (P4/E2) for the Greater Caribbean manatee. Using non‐invasive ELISA, the authors found no significant differences between mature and immature females, highlighting that long‐term monitoring and ultrasounds are essential to fully understand their complex reproductive cycles.

What Happens After Menopause (WHAM)? A Progress Report of a Prospective Controlled Study of Women After Pre‐Menopausal Risk‐Reducing Bilateral Salpingo‐Oophorectomy

open access: yesBJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Surgical menopause, the removal of both ovaries prior to natural menopause, may impact short‐and long‐term physical and emotional health. An increasingly common cause of surgical menopause is risk‐reducing salpingo‐oophorectomy (RRSO) in those at high inherited risk of ovarian cancer.

Brain aromatase (Cyp19a1b) is a highly sensitive gene to estrogens and xeno-estrogens [PDF]

open access: yes, 2012
International audienceAromatase is the only enzyme responsible for the irreversible conversion of androgens into estrogens. Teleost fishes have two copies of the cyp19a1 gene that encode two isoforms of aromatase: cyp19a1a encodes ovarian aromatase ...
