Thirty-nine multiparous ewes (19 Pelibuey and 20 Romanov × Pelibuey) treated with fluorogestone acetate impregnated intravaginal sponges were used to evaluate the effects of low pregnant mare serum go...
The luteal blood flow, area and pixel intensity of corpus luteum, levels of progesterone in pregnant and nonpregnant mares in the period of 16 days after ovulation
horse pregnancy ultrasonic imaging Doppler ultrasonography image analysis
2015/6/24
The objective of the present study was to examine if luteal blood flow (LBF) monitoring could be used as an additional prognostic tool for early pregnancy diagnosis, and we particularly focused on the...
Effects of season on plasma progesterone profiles in repeat breeding cows
embryonic death luteal function season cows
2015/5/25
Twenty eight (60.9%) and 18 (39.1%) cows were followed in summer (June–August)
and winter (December–February), respectively. In the summer season, the total progesterone concentrations were
higher...

TLR4 flow cytometry oxidative burst phagocytosis pyometra dog
2015/4/17
To date, only limited information about the influence of ovarian hormones on canine immune system cells has been available. The study investigated the in vitro influence of progesterone and estradiol-...
A one-foetus pregnancy monitored by ultrasonography and progesterone blood levels in a German Shepherd bitch: a case report
singleton litter ultrasonography pregnancy hypoluteoidism dog

Genomic and non-genomic effects of progesterone and pregnenolone on the function of bovine endometrial cells
non-genomic effect progesterone progesterone membrane receptor component 1
2015/4/2
Progesterone (P) decreases oxytocin (OT)-stimulated prostaglandin (PG)F2α, but not PGE2 secretion from bovine endometrial cells and this effect is partly elicited via a non-genomic route. The aim of t...
