Does synchronising follicular wave emergence improve outcomes in non‐superstimulated donor cattle undergoing ovum pick‐up (OPU) for in vitro embryo production?

Australian Veterinary Journal, EarlyView.
In vitro embryo production (IVEP) is now a widely commercialised assisted reproductive technology used in cattle reproduction. The use of follicle‐stimulating hormone (FSH) to superstimulate donor cattle prior to ovum pick‐up (OPU) is generally regarded as an effective strategy to improve oocyte quality, developmental competence and increase embryo ...

Microvascularization of corpus luteum of bovine treated with equine chorionic gonadotropin

Microscopy Research and Technique, 2015
ABSTRACTThis study aimed to evaluate the morphological changes in microvascular density and corpus luteum (CL) vascularization in cows treated with eCG during stimulatory and superovulatory protocols. Sixteen cows were synchronized and divided into three groups: control (n = 6), stimulated (n = 4) and superovulated (n =6), one was submitted to estrous ...

Immunocytochemical Localization of Luteinizing Hormone and Follicle-Stimulating Hormone in the Equine Pituitary

, 1998
Gonadotropin-specific primary antisera and gold-conjugated secondary antibodies were used to immunocytochemically localize gonadotropins in the anterior pituitary of intact pony mares.

Dietary L‐Tyrosine Sustains Egg Production and Quality by Modulating Promoter CpG Methylation, Gene Expression, and Hormone Profiles in Reproductive Signalling Pathways of Aged Laying Hens

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Managing prolactin (PRL)‐mediated reproductive suppression is critical for maintaining egg production in commercial laying hens. L‐tyrosine (TYR), a precursor of dopamine (DA), may counteract age‐related reproductive decline by suppressing PRL, thereby sustaining productivity and egg quality in late‐phase laying hens.

Menopause and vascular endothelial health: Is it all about the oestrogen?

Experimental Physiology, EarlyView.
Abstract Cardiovascular disease (CVD) is a leading cause of mortality in women, and CVD risk is accelerated during the menopause transition. This acceleration has traditionally been attributed to the hallmark decline in oestradiol with menopause. However, the menopause transition is also characterized by changes in other sex hormones that exert effects

Molecular characterization, modeling, in silico analysis of equine pituitary gonadotropin alpha subunit and docking interaction studies with ganirelix

, 2017
Equine pituitary gonadotropins (eLH, eFSH, eCG) are heterodimeric glycoprotein hormones with alpha (α) and beta (β) subunits. It is responsible for maintenance of pregnancy in mares during early gestation and fairly valuable for inducing superovulation ...

Polymorphism of the Gonadotropin‐Releasing Hormone Receptor Gene and Its Association With Production Traits in Isfahani Native Hens

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
This research was conducted to identify genetic polymorphisms of the GNRHR gene on Isfahan native hen traits and their relationship with production traits. For this purpose, blood was taken, DNA was extracted, the target fragment was amplified and directly sequenced, and finally it was blasted with the reference gene in NCBI.

Comparative Effects of Laparotomy and Laparoscopy‐Assisted Embryo Transfer on Oxidative Stress and Thiol–Disulphide Homeostasis in Tuj Ewes

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Laparoscopic embryo transfer in Tuj ewes induces less oxidative stress and better preserves thiol–disulphide homeostasis than laparotomy. These findings indicate that minimally invasive approaches better maintain redox balance and antioxidant defence during embryo transfer procedures.

Dried blood spot analysis in antidoping: Technical challenges, analytical advances, and future perspectives

Bulletin of the Korean Chemical Society, Volume 47, Issue 6, Page 674-688, June 2026.
Dried blood spot (DBS) analysis enables minimally invasive blood collection with strong analyte stability and simplified logistics, supporting anti‐doping applications beyond traditional matrices. Recent advances address hematocrit, volume variability, and matrix effects while expanding coverage to steroid esters, World Anti‐Doping Agency‐listed ...

Women with epilepsy: Evidence‐based counseling across the lifespan

Epilepsia, Volume 67, Issue 6, Page 2689-2706, June 2026.
Abstract Women with epilepsy (WWE) encounter distinct and evolving challenges across the lifespan that require clinical management extending beyond seizure control alone. Although awareness of sex‐specific aspects of epilepsy has increased, important gaps remain in their integration into routine care.
