O presente estudo objetivou diagnosticar as causas da morte embrionaria precoce em 128 eguas. Amostras de soro foram coletadas nos dias 4, 7, 10, 13, 16, 19, 21 e 30 apos ovulacao, para dosagens… Expand
Plasma concentrations of 13,14-dihydro-15-keto prostaglandin F2-alpha (PGFM), progesterone and estradiol in pregnant and nonpregnant diestrus cross-bred bitches.
The canine corpus luteum (CL) typically sustains elevated plasma progesterone concentrations for 2 months or more, with a peak approximately 15-25 days after ovulation, followed by a slow decline.… Expand
Characteristics of seminal plasma proteins and their correlation with canine semen analysis
Abstract The objectives were to separate canine seminal plasma proteins (with SDS-PAGE) and to determine the correlation between specific proteins… Expand
In vitro PGF2alpha production by endometrium and corpus luteum explants from pregnant and nonpregnant diestrus bitches and placental explants from pregnant bitches.
To better understand the process of slow luteal regression of the nonpregnant cycle in dogs and the acute luteolysis that occurs prepartum, the present study investigated in vitro PGF2alpha… Expand
Use of corticosteroid therapy on the modulation of uterine inflammatory response in mares after artificial insemination with frozen semen
In order to modulate uterine inflammatory response and evaluate the effect of corticosteroid therapy on fertility, 90 cycles of 45 mares were used for artificial insemination with frozen semen, using… Expand
