Higher environmental temperature is one of the major factors responsible for reduced fertility in farm animals. Heat stress causes a great suppression in endometrial function [1] besides compromised follicular growth [2], embryonic function [3] and oocyte developmental potential [4]. Heat stress also increases the production of PGF2α in the endometrium, leading to the early regression of CL or the death of embryos [5]. Heat stress-induced hyperthermia has been found to decrease the pregnancy… Expand

Impact of in Vitro Heat Shock (42.50c) on Prostaglandins, Ionic and Metabolic Contents in Sheep Endometrial Epithelial Cells
TLDR
The present study investigated the effect of heat shock on prostaglandins, ionic and metabolic contents of sheep endometrial epithelial cells in vitro and found increased PGF2α synthetic capacity of endometrium exposed to heat stress may be due to heat-induced alterations in endometrian cellular membranes.

Heat stress-induced alterations in the synthesis and secretion of proteins and prostaglandins by cultured bovine conceptuses and uterine endometrium.
Effect of in vitro heat stress on protein and prostaglandin synthesis and secretion by bovine conceptuses and endometrium was examined. Conceptuses (n = 11) and endometrium (n = 10) obtained on DayExpand
Effect of day of the oestrous cycle, side of the reproductive tract and heat shock on in-vitro protein secretion by bovine endometrium.
TLDR
Endometrial protein secretion changes quantitatively during the early oestrous cycle, and there is a local influence of the ovary bearing the corpus luteum on endometrial function that may be disrupted by heat shock. Expand
Increases in mouse uterine heat shock protein levels are a sensitive and specific response to uterotrophic agents.
TLDR
The results of this study suggest that only the estrogens increase uterine hsp90alpha and grp94 levels, and that this hsp effect is a more sensitive uterotrophic response than uterine weight increase. Expand

TLDR
The conceptus secretes an interferon-tau (previously named trophoblast protein-1) which prevents oestradiol and oxytocin acting on a progesterone-primed uterus from stimulating endometrial PGF2 alpha synthesis during early pregnancy in other species. Expand
Developmental changes in embryonic resistance to adverse effects of maternal heat stress in cows.
TLDR
Bovine embryos become more resistant to adverse effects of maternal heat stress as pregnancy progresses; substantial resistance develops by d 3. Expand
Effect of season and exposure to heat stress on oocyte competence in Holstein cows.
TLDR
Oocytes from the two largest follicles per cow were aspirated and cultured individually and proportions of oocytes and cleaved embryos that developed to blastocysts by d 8 were lower in summer than winter with no difference between the heat-stressed and the cooled treatment groups. Expand
Stimulation of phosphoinositide hydrolysis by oxytocin and the mechanism by which oxytocin controls prostaglandin synthesis in the ovine endometrium.
TLDR
It is proposed that the stimulation of endometrial prostaglandin synthesis by oxytocin is accounted for by increased hydrolysis of phosphoinositides to diacylglycerol and inositol phosphates with subsequent release of arachidonic acid from diacydonic acid. Expand
Embryonic development in superovulated dairy cattle exposed to elevated ambient temperatures between the onset of estrus and insemination
TLDR
Data indicate that thermal stress during the periovulatory period increases the incidence of retarded and/or abnormal embryos in superovulated heifers. Expand
Embryonic development in superovulated dairy cattle exposed to elevated ambient temperatures between Days 1 to 7 post insemination.
TLDR
Responses indicated that thermal stress from 30 h after the onset of estrus to Day 7 post estrus increases the incidence of abnormal and retarded embryos in superovulated heifers. Expand
ISOLATION, CULTURE AND CHARACTERIZATION OF ENDOMETRIAL EPITHELIAL CELLS IN BUFFALO (BUBALUS BUBALIS)
TLDR
It was concluded that buffalo endometrial epithelial cells could serve as an excellent model for studying the specific role of PGF 2α in maternal recognition of pregnancy and implantation. Expand
