nonsignificant differences between cutoffs for serum and plasma and between assays are encouraging regarding the ease of interpretation by clinicians and laboratories. Also encouraging were improvements in the analytical sensitivity of these newergeneration assays. Interestingly, only 3 samples were identified as above the 99th percentile by all 3 assays. The mechanisms responsible for this lac...

Background: Human chorionic gonadotropin (hCG) is a member of glycoprotein hormones family consist of two different non-covalently heterodimeric chains: alpha and beta subunits with 92 and 145 amino acids respectively. This hormone plays an important role in human reproduction and physiology especially for maintenance of the corpus luteum during the first months of pregnancy Materials and Metho...

introduction: considering the high incidence of preterm labor and its known complications, and that human myometrium contains receptors for human chronic gonadotropin (hcg) and that hcg can inhibit myometrial contractions on vitro, made me study treating effects of hcg on preterm labor. this clinical trial study was carried out to compare the effect of hcg, and magnesium sulfate (mgso4) on prev...

Testicular germ cell tumors (TGCTs) represent the most common type of solid tumors among men aged 15 to 40 years. An increasing incidence has been recorded in developed countries. In clinical practice, TGCTs are classified as seminomas and non-seminomatous tumors. Non-seminomatous tumors often contain multiple different cell types and can be further sub-divided according to the histological and...

Serial injections (i.m.) of 10 mg follicle stimulating hormone (FSFI-P) to cheetahs for 5 days followed by human chorionic gonadotropin (hCG, 500 IU) administered on both Days 6 and 7 resulted in ovarian follicle development and/or ovulation in six of seven attempts. One additional female given the same gonadotropin regimen when distinct corpora lutea (CL) were visible on the ovaries failed to ...
