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, Volume 104, Issue 7, Page 447-456, July 2026.
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 ...

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 ...

Physical-chemical and biological characterization of different preparations of equine chorionic gonadotropin

Journal of Veterinary Science, 2016
Ovarian stimulation with commercial preparations of equine chorionic gonadotropin (eCG) produces extremely variable responses in domestic animals, ranging from excessive stimulation to practically no stimulation, when applied on the basis of their declared unitage.

Effect of Tyrosine Modification on the Biological and Immunological Properties of Equine Chorionic Gonadotropin

Experimental Biology and Medicine, 1984
The tyrosine residues of equine chorionic gonadotropin have been nitrated with tetranitromethane and the resulting effects on the biological and immunological activities of the hormone studied. All of the tyrosine residues in equine chorionic gonadotropin were found to react with tetranitromethane when a 100-fold molar excess of reagent was used or ...

Demonstration of a COOH-terminal extension on equine lutropin by means of a common acid-labile bond in equine lutropin and equine chorionic gonadotropin.

Journal of Biological Chemistry, 1985
The beta subunits of equine lutropin and equine chorionic gonadotropin were incubated in 0.013 N HCl for 30 min at 110 degrees C and separated into two fragments by reverse-phase high performance liquid chromatography. The amino acid and carbohydrate compositions of both fragments from each subunit were analyzed.
