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.

Multiple eumenorrheic cycles are necessary to observe a significant increase in estrogen exposure and ovulation in exercising women with functional hypothalamic oligo/amenorrhea undergoing a nutritional intervention: Insights from the REFUEL study

PM&R, EarlyView.
Abstract Background Due to consequences of energy‐related oligo‐/amenorrhea (Oligo/Amen) among exercising females, recovery of menses (ROM) is a priority. ROM is inconsistently defined and rarely reported with reproductive hormone (estrogen, progesterone) data, making it difficult to know when females achieve adequate recovery. Objective The purpose of

Evaluation of a non‐radioactive rapid test for determination of serum progesterone in South American camelids

Veterinary Record, EarlyView.
Abstract Background Determination of the serum progesterone (P4) concentration is of high importance in reproductive medicine and may be applied for diagnosing pregnancy in South American camelids. P4 measurements in alpacas and llamas are usually performed using immunoassays, which are time consuming and require appropriate expertise of laboratory ...

Metabolism of sex hormones in the aortic wall

Journal of Lipid Research, 1968
The metabolism of labeled sex hormones was examined in human, canine, and rat aortas. Isolated arterial tissue converted estrone to estradiol, estradiol to estrone, and estrone sulfate to estrone and estradiol.

Advances in cholesterol and lipoproteins detection for healthcare: A review

VIEW, EarlyView.
Cholesterol is one of the main biomarkers related to the development of cardiovascular diseases. Its detection still relies on traditional methods of analysis, such as gas and liquid chromatographies. Detection of free cholesterol in saliva with redox or enzymatic sensors or detection of lipoproteins in blood with aptamer sensors are currently the most

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

Wildlife 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.

The Role of Vaginal Oestrogen Therapy in Postmenopausal Women With Pelvic Organ Prolapse: Does It Have Any Impact on Perioperative Outcomes? A Systematic Review of Randomised Controlled Trials

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Background Pelvic organ prolapse (POP) affects up to 50% of postmenopausal women, negatively impacting sexual function and quality of life. While surgery remains the primary treatment, increasing attention has been given to perioperative vaginal oestrogen therapy and its potential impact on surgical outcomes.

INSL3 Expression in Leydig Cells is a Biomarker for Immunocastration in Boars: Transcriptional Evidence

Andrology, EarlyView.
ABSTRACT Background Study aimed to obtain insights into physiological responses to immunocastration in pubertal boars by evaluating effects of alternative vaccination protocols and identifying a reliable immunocastration biomarker. Objectives It was hypothesized that the timing of gonadotropin‐releasing hormone (GnRH) suppression by immunocastration ...
