Human heterophile antibodies may develop after infection or contact with animal tissues or animal serum products. These antibodies have the capacity to bind to the animal immunoglobulins used in immunoassays leading to erroneous results. We here report a case of a testicular germ cell tumor patient who developed heterophile antibodies during the surveillance period of his disease. Following fal...

OBJECTIVE: To compare the effectiveness of uterine artery Doppler and maternal serum screening in the prediction of pregnancy complications. MATERIALS AND METHODS: Prospective study with 49 primigravidae at their 18th gestational week, when a blood sample was collected for serum dosage by chemiluminescence (alpha-fetoprotein, human chorionic gonadotropin and nitric oxide) and radioimmunoassay (...

OBJECTIVE The aim of the present study was to evaluate the effects of fetal gender on serum human chorionic gonadotropin (hCG) and testosterone in normotensive and preeclamptic pregnancies. METHODS The study consisted of 137 women with singleton pregnancies in the third trimester. Seventy-three pregnancies were uncomplicated; among those were 35 male and 38 female fetuses. Sixty-four pregnanc...

Background: During early pregnancy raised beta human chorionic gonadotropin (β-HCG) level occurs during placental development. It may be used for identifying the induced hypertension. There are certain factors that causes hypertension and preeclampsia. However, many of associated specific cause is not known. Some common risk preeclampsia nulliparity, in a previous pregnancy, family history, his...

Administration of human chorionic gonadotropin (HCG) to prepubertal Thoroughbred colts results in significant increases in serum testosterone concentrations. Colts with cryptorchid testicles have a reduced response in testosterone concentration compared to colts with descended testicles. Treatment with HCG facilitates descent of inguinally located testicles. Author’s address: Large Animal Medic...

Objective: Reproductive biotechnology studies focus on the longterm storage of embryos (cryopreservation), embryo cultures, genome editing and transfer. Micromanipulation techniques in reproduction biotechnologies have an important role, especially investigating assisted reproductive technology laboratory animals. The aim present study was to investigate effect epididymal spermatozoa injected o...
