The Impact of Soy Products and Isoflavones on Male Reproductive Hormones: A Systematic Review and Dose–Response Meta‐Analysis of Randomized Controlled Trials

Food Frontiers, EarlyView.
ABSTRACT Given the growing evidence that soy may exhibit estrogenic effects in males under certain conditions, it was essential to conduct a comprehensive study to elucidate this. This dose–response meta‐analysis of randomized controlled trials was conducted to investigate the effects of soy and its products on male sex hormones.

Separation and lipophilicity of some new steroid derivatives in normal- and reversed-phase high performance liquid chromatography [PDF]

Chemical Industry and Chemical Engineering Quarterly, 2011
The separation ability and retention of normal and reversed phase HPLC with, respectively, three non-polar and two polar mobile phases, have been studied by measuring the retention constants of a series of newly synthesized estrone derivatives.

Synthesis and Antiproliferative Activity of Steroidal Diaryl Ethers

Molecules, 2023
Novel 13α-estrone derivatives have been synthesized via direct arylation of the phenolic hydroxy function. Chan–Lam couplings of arylboronic acids with 13α-estrone as a nucleophilic partner were carried out under copper catalysis.

Medical treatment of fibroids: FIGO best practice guidance

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Even though uterine fibroids are a widespread condition, the range of approved medical treatment options remains limited. In fact, only a few drugs are officially approved for the therapy of fibroids. In both the USA and the European Medicines Agency region, selected gonadotropin‐releasing hormone (GnRH) antagonists have been approved for this

Dissociation between Cervical Mucus and Urinary Hormones during the Postpartum Return of Fertility in Breastfeeding Women [PDF]

, 2018
Identifying the return of fertility with cervical mucus observations is challenging during the postpartum period. Use of urinary measurements of estrogen and progesterone can assist in understanding the return to fertility during this period.

Perinatal Exposure to the Neonicotinoid Thiacloprid Impacts Transcription of Neuroplasticity and Neuroendocrine Markers in Mice but Not in the Zebrafish Model

Journal of Applied Toxicology, EarlyView.
ABSTRACT Neonicotinoids are widely used insecticides in agriculture, aquaculture, pet care, and urban pest control. Initially developed to selectively target the insect cholinergic system, their extensive use has raised concerns about adverse effects on nontarget vertebrates.

Palladium-catalyzed acetylation of arenes. [PDF]

, 2014
A simple method for the preparation of aryl methyl ketones is reported. The transformation involves the Pd-catalyzed coupling of an acyl anion equivalent, acetyltrimethylsilane, with aryl bromides to afford the corresponding acetylated arenes in ...

Bifenthrin Under Scrutiny: Revisiting Toxicological Evidence Amid Regulatory Gaps

Journal of Applied Toxicology, EarlyView.
ABSTRACT Despite growing health concerns, bifenthrin (BF) remains widely used for controlling agricultural and residential pests. However, different perspectives on its toxicological profile and regulatory framework warrant a revisit and update on BF regulation towards a robust risk‐safety assessment.
