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 ...

Transport of estrone 3-sulfate mediated by organic anion transporter OATP4C1: estrone 3-sulfate binds to the different recognition site for digoxin in OATP4C1. [PDF]

, 2010
Human organic anion transporter OATP4C1 is a member of the OATP family predominantly expressed in the kidney, and contributes to the renal secretion of digoxin. However, little is known about the characteristics of OATP4C1-madiated transport. We examined

Remote Desaturation of Unprotected Amines and C─H Amination of Alkanes by Polarity‐Matched N‐Radical Cations

Angewandte Chemie, Volume 138, Issue 40, 28 September 2026.
Highly electrophilic N‐radical cations enable efficient and selective H‐atom transfer (HAT) of unprotected amines. In this exceedingly practical strategy, simple CuCl catalyzes an interrupted Hofmann–Löffler–Freytag (HLF) reaction to afford δ desaturated amines, aza‐heterocycles, and C─H aminated alkanes without protecting groups.

The effects of moderate alcohol supplementation on estrone sulfate and DHEAS in postmenopausal women in a controlled feeding study

Nutrition Journal, 2004
Background We have demonstrated that moderate alcohol consumption (15 g/d, 30 g/d) for 8 weeks resulted in significantly increased levels of serum estrone sulfate and DHEAS in 51 postmenopausal women in a randomized, placebo-controlled trial.

Evaluation of a commercial automated assay for rapid serum progesterone determination in cattle, sheep and goats

Veterinary Record, EarlyView.
Abstract Background In ruminants, information on serum progesterone concentrations can be important in monitoring the oestrous cycle for pregnancy testing and the detection of endocrine disorders. We aimed to evaluate the suitability of a commercial enzyme‐linked fluorescence assay (ELFA), the MINI VIDAS (bioMérieux, Nürtingen), for measuring ...

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.

PHOSPHONATES AND THIOPHOSPHONATES AS SULFATE SURROGATES - SYNTHESIS OF ESTRONE 3-METHYLTHIOPHOSPHONATE, A POTENT INHIBITOR OF ESTRONE SULFATASE

, 1993
Estrone 3-phosphonates and thiophosphonates have been synthesised as analogues of estrone 3-sulfate and exhibit potent activity as competitive inhibitors of estrone sulfatase, a potential therapeutic target in treatment of breast cancer.

The Role of Estrone in Feminizing Hormone Treatment

, 2022
CONTEXT: In trans women, hormone treatment induces feminization; however, the degree of feminization varies from person to person. A possible contributing factor could be estrone, a weak estrogen that interferes with the estrogen receptor.

Lumiestrone is photochemically derived from estrone and may be released to the environment without detection

Frontiers in Endocrinology, 2011
Endocrine disrupting chemicals are adversely affecting the reproductive health and metabolic status of aquatic vertebrates. Estrone is often the dominant natural estrogen in urban sewage, yet little is known about its environmental fate and biological ...

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.
