Markers of pregnancy: How early can we detect pregnancies in cattle using pregnancy-associated glycoproteins (PAGs) and microRNAs?
Pregnancy detection has evolved over the last few decades and the importance of early pregnancy detection is critical to minimize the amount of time a cow spends not pregnant. Embryonic mortality (EM) is generally considered ...
Correlates of early pregnancy serum brain-derived neurotrophic factor in a Peruvian population
Knowledge about factors that influence serum brain-derived neurotrophic factor (BDNF) concentrations during early pregnancy is lacking. The aim of the study is to examine the correlates of early pregnancy serum BDNF ...
Pregnancy Associated Glycoprotein (PAG) Concentrations at Day 24 Gestation from Dairy Heifers Predicted to Maintain Pregnancy.

Early pregnancy diagnosis in alpaca (Lama pacos) and llama (Lama glama) by ultrasound
An ultrasonography study of early pregnancy diagnosis was carried out in 19 alpacas and 12 llamas, after controlled matings. The aim was to determine the earliest gestational age at which pregnancy diagnosis by transrectal ...
Expression of receptors for ovarian steroids and prostaglandin E2 in the endometrium and myometrium of mares during estrus, diestrus and early pregnancy
(Elsevier B.V., 2014-12-30)
The objective of this study was to compare expression of estrogen receptor alpha (ER-alpha), beta (ER-beta), progesterone receptor (PR), as well as prostaglandin E2 type 2 (EP2) and 4 (EP4) receptors in the equine myometrium ...
Using pregnancy-associated glycoproteins to provide early pregnancy diagnosis in Nelore cows
(Elsevier B.V., 2018-08-01)
Pregnancy-associated glycoproteins (PAG) are expressed in the placenta of ungulate mammals. Ruminants secrete PAGs continuously from embryonic implantation until delivery. In this study, we evaluated the feasibility of ...
Serum markers in the diagnosis of tubal pregnancy
(Faculdade de Medicina / USP, 2008)
The introduction of highly sensitive methods, such as transvaginal sonography and measurement of serum b-human chorionic gonadotropin, has dramatically improved ectopic pregnancy diagnosis in recent years. Early diagnosis ...
