Identification and differentiation of somapacitan, a long-acting growth hormone derivative, and recombinant human growth hormone in equine plasma by LC-HRMS for doping control purpose. Shimizu Y, Sugai-Bannai M, Saito K, Hirano-Kodaira M, Leung GN.Somapacitan, a long-acting growth hormone derivative, and recombinant human growth hormone (rhGH) are protein-based drugs generally used to treat growth disorders and GH deficiency in humans. Due to their potential to enhance the horse performance, the use of these drugs is prohibited at-all-times by the International Federation of Horseracing Authorities for horseracing and the Fédération Equestre Internationale for equestrian sports. In this study, we developed a test method for the identification and differentiation of somapacitan and rhGH in equine plasma by using liquid chromatography h...

Reproductive biology    November 9, 2024   Volume 24, Issue 4 100967 doi: 10.1016/j.repbio.2024.100967
Gabryś J, Pietras N, Kowal-Mierzwa W, Karnas E, Andronowska A, Nowak A, Kochan J, Bugno-Poniewierska M.The efficacy of in vitro embryo production (IVEP) in equines is relatively limited compared to other species due to the lack of a reliable superovulation technique, limited availability of cumulus oocyte complexes (COCs), low in vitro oocyte maturation (IVM) and fertilization rates. Extracellular vesicles (EVs), which are nanoparticles involved in intercellular signaling in the ovarian environment, have shown potential as supplements to improve oocyte development during IVM. This study tested the hypothesis that EVs from small (< 20 mm) ovarian follicles could enhance fertilization rates i...
Application of the horse grimace scale in horses with dental disease: Preliminary findings.
The Veterinary record    November 9, 2024   Volume 196, Issue 3 e4800 doi: 10.1002/vetr.4800
Sidwell AE, Duz M, Hill B, Freeman S, Hole SL.Dental disease is a common but often under-recognised condition in horses, possibly due to an inability to recognise clinical signs of oral discomfort. Some dental disorders are reportedly more painful than others, but there is no current metric by which dental pain can be objectively assessed. This study aimed to determine whether a facial expression-based pain scale offered an objective and reliable method for assessing dental pain in horses. It was hypothesised that dental disorders affecting the periodontium would produce high pain scores. Twelve horses with dental disease were evaluated f...

The results revealed that spray-dried milk powder exhibited a smaller particle size, lower air content within the powder particles, inferior reconstitution properties, and lower lactose crystallinity compared with freeze-...
Association of Equine Squamous and Glandular Gastric Disease with Dental Status in 54 Horses.
Animals : an open access journal from MDPI    November 7, 2024   Volume 14, Issue 22 3189 doi: 10.3390/ani14223189
Lensing R, Wirth C, Thünker F, Merle R, Barton AK.Gastric pH is a key factor in the development of equine squamous gastric disease (ESGD). Although acid injury is unlikely the primary cause of equine glandular gastric disease (EGGD), low pH may promote mucosal damage. Gastric pH is influenced by roughage uptake, as chewing increases the alkaline saliva production. The proton pump inhibitor omeprazole is currently recommended by the American/European College of Veterinary/Equine Internal Medicine (ACVIM/ECEIM) for ESGD and EGGD. We hypothesized that dental disorders decrease saliva production and gastric pH, predisposing horses to EGUS. Gastro...
Detection of equine parvovirus-hepatitis and efficacy of governmental regulation for equine biologics purity. Scupham AJ, Tong C.In 2018, a new virus, named equine parvovirus-hepatitis (EqPV-H), was discovered in a biologic product that had been administered to horses that subsequently developed clinical signs of equine serum hepatitis (Theiler disease). Further correlation of the virus with the disease sparked federal requirements that all equine biologics be free of EqPV-H. The initial quantitative real-time PCR (qPCR) test for EqPV-H has proved to be sensitive to co-extracted PCR inhibitors in template nucleic acids, causing false-negative results. We investigated the use of digital PCR (dPCR) as a more robust test. ...
