The time course of chorionic gonadotropin stimulation of nuclear basic and acidic protein biosynthesis, phosphorylation, and acetylation as well as DNA biosynthesis in ovaries of immature rats has been investigated. After injection of radioactive precursor and chorionic gonadotropin into immature rats, ovarian histone fractions Fl, FZal, F2a2, F2b, and F3 were isolated by selective acid extract...

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 ...

context maternal serum human chorionic gonadotropin (hcg) and alpha fetal protein (afp) were originally introduced to detect trisomy 21 and neural tube defects. however, in the absence of aneuploidy or neural tube defects, mid-trimester maternal serum hcg and/or maternal serum afp associated with adverse pregnancy outcomes. pregnancies with unexplained mid-trimester elevation in maternal serum ...

Choriocarcinoma is a curable malignancy that occurred approximately 50% after term pregnancies, and prognosis in this form of gestational trophoblastic Disease (GTD) is Poor. The earliest onset choriocarcinoma after term pregnancy in one study was reported 3 weeks after delivery, but in current study, choriocarcinoma was diagnosed 2 weeks after delivery. 28 years-old women gravidity 2, parity 2...

Treatment with colchicine or x-radiation of a human embryonal carcinoma of testicular origin, which has secreted a chorionic gonadotropin-like hormone in ~0 per cent of heterografted hosts, resulted in a 2 89 times increase in the incidence of chorionic gonadotropin-secreting tumors as determined in oophorectomized and hypophysectomized animals. Lines developed from three of the tumors treated ...

We studied the in vitro effect of dipyrone on the determination of free triiodothyronine (free T3), cortisol, progesterone, estradiol, carcinoembryonic antigen, human chorionic gonadotropin and alpha-fetoprotein measured with an immunoenzyme assay based on enhanced luminescence that uses peroxidase as label. We found significant interference from dipyrone (p < 0.01) in the determination of all ...
