Temporal changes in Neutral Endopeptidase/CD10 immunoexpression in the cyclic a...

CD10 is a multifunctional transmembrane neutral endopeptidase (NEP), considered to be a reliable marker of ectopic human endometrial stroma. Available information in NEP/CD10 protein expression in animal endometria is scarce. This study focused on the immunolocalization of NEP/CD10 in the canine uterus and on its temporal changes during the oestrous cycle and early pregnancy (days 11 to 23 post-LH surge) in hea...

Body condition score (BCS) may be used to assess a donkey’s welfare and nutritional status, but the procedure is highly subjective. For several domestic species the relationships between the ultrasound subcutaneous fat depth, the body condition score and the body subcutaneous fat distributi...

Freemartinism in Cattle

Freemartinism is one of the most commonly found intersex conditions in cattle, although it may also occur in small ruminants. The freemartin phenotype appears in a dizygotic twin pregnancy where one twin is a male and the other is a female. Due to precocious anastomoses between the placental vascular systems of the two fetuses, masculinising molecules reach the female twin and disrupt the normal sexual differen...
