Feasibility of a liver transcriptomics approach to assess bovine treatment with the prohormone dehydroepiandrosterone (DHEA)

, 2010
Background Within the European Union the use of growth promoting agents in animal production is prohibited. Illegal use of natural prohormones like dehydroepiandrosterone (DHEA) is hard to prove since prohormones are strongly metabolized in vivo.

Dehydroepiandrosterone exacerbates nigericin-induced abnormal autophagy and pyroptosis via GPER activation in LPS-primed macrophages

Cell Death and Disease, 2022
As a widely acknowledged FDA-approved dietary supplement or over-the-counter medicines, dehydroepiandrosterone (DHEA) exerts anti-inflammatory and immunomodulatory function. Pyroptosis is an important form of programmed cell death (PCD), and which acts a

Identification of Synthetic Urine by Analysis of Stable Carbon and Nitrogen Isotope Ratios and Comparison to Established GC‐MS/MS and LC‐MS/MS Analysis

Drug Testing and Analysis, EarlyView.
This study compared GC‐MS/MS, EA‐IRMS, and LC‐MS/MS for detecting synthetic and manipulated urine samples in doping control and forensic analysis. EA‐IRMS proved particularly effective for identifying mixtures of synthetic and authentic urine, providing a reliable complement to established authenticity testing methods.

Subclinical cardiac alterations and cardiometabolic profile in adolescents with newly diagnosed polycystic ovary syndrome: A cross‐sectional comparative echocardiographic study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective While cardiometabolic comorbidities have been well established in adults with polycystic ovary syndrome (PCOS), it remains unclear whether the early signs of cardiovascular morbidity emerge during adolescence. This study aimed to investigate whether metabolic and cardiovascular alterations begin in adolescents with PCOS.

Toxic Effects of Bisphenol A and Its Analogs on Ovarian Structure and Function: A Narrative Review of Ovary‐Focused Studies

Journal of Applied Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA) is a widely used industrial chemical found in polycarbonate plastics and epoxy resins and is recognized for its endocrine‐disrupting properties. Human exposure is common due to its presence in food packaging and everyday products. As BPA use has been restricted, structurally similar compounds such as BPS, BPB, BPAF, and BADGE

Dynamics of adrenal steroids are related to variations in Th1 and Treg populations during Mycobacterium tuberculosis infection in HIV positive persons. [PDF]

PLoS ONE, 2012
Tuberculosis (TB) remains the most frequent cause of illness and death from an infectious agent, and its interaction with HIV has devastating effects. We determined plasma levels of dehydroepiandrosterone (DHEA), its circulating form DHEA-suphate (DHEA-s)
