Role of PGF2a in luteolysis based on inhibition of PGF2a synthesis in the mare [PDF]

open access: yes, 2013
The effects of inhibition of PGF2α synthesis on luteolysis in mares and on the incidence of prolonged luteal activity were studied in controls and in a group treated with flunixin meglumine (FM), a PGF2α inhibitor (n = 6/group).

Effects of Prepartum Supplementation and Yeast Fermentation Products on the Progesterone‐Modulated Transfer of Passive Immunity in Bos indicus Cows

open access: yesJournal of Animal Physiology and Animal Nutrition, Volume 110, Issue 4, Page 463-473, July 2026.
ABSTRACT Inadequate colostrum intake increases risks of calf morbidity and mortality. This study investigated the effects of prepartum and early postpartum supplementation and yeast fermentation products on late‐pregnant Bos indicus cows, and the role of progesterone in mediating passive immunity transfer.

Towards a Safe Pathway to Biological Parenthood for Pulmonary Arterial Hypertension

open access: yesPulmonary Circulation, Volume 16, Issue 2, April 2026.
ABSTRACT Pulmonary arterial hypertension (PAH) carries a high risk of maternal morbidity and mortality in pregnancy, and current guidelines advise against conception. For women with PAH who wish to have genetically related children, in vitro fertilisation (IVF) combined with gestational surrogacy presents a viable and increasingly safe alternative ...

Expression patterns of Toll-like receptors in the ovine corpus luteum during the early pregnancy and prostaglandin F2α-induced luteolysis [PDF]

open access: yes, 2018
The aim of this study was to elucidate the expression profiles of Toll-like receptors (TLRs) in the ovine corpus luteum (CL) during early pregnancy and prostaglandin F2 alpha (PGF2 alpha)-induced luteolysis. For this purpose, multiparous Anatolian Merino

Reproductive and Perinatal Outcomes of Embryo Transfer in Elite Hanwoo Cows

open access: yesVeterinary Medicine and Science, Volume 12, Issue 2, March 2026.
Reproductive outcomes following embryo transfer in Elite Hanwoo cows differed by embryo production method. OPU‐IVF was associated with higher abortion, increased birth weight of male calves and greater dystocia risk, whereas MOET resulted in more favourable calving outcomes, highlighting the importance of embryo production strategy and periparturient ...
