2015/7/2
Forty non-lactating, cyclic adult Pelibuey ewes were randomly divided into six groups. Estrus was synchronized within each group using intravaginal sponges and prostaglandin F2α injection at the time ...
Changes in serum concentration of 17 beta-estradiol in female rats during estrous cycle after treatment with atrazine and zearalenone
atrazine zearalenone estrous cycle
2015/1/20
A daily dose of 14 mg atrazine and 2.5 mg zearalenone, given p.o. during 5 days of estrous cycle to female rats, changed their estrous cycle in comparison with control animals. On day –1 of expected e...
Activated Leukocyte Cell Adhesion Molecule: Expression in the Uterine Endometrium during the Estrous Cycle and Pregnancy in Pigs
Pig Pregnancy Uterus Endometrium ALCAM
2016/5/6
The pig exhibits true epitheliochorial placentation, where the fetal membrane maintains attachment throughout pregnancy but does not invade into the maternal uterine endometrium. Accordingly, the expr...
