Human chorionic gonadotropin has been used for decades, in addition to specific investigations, to detect pregnancy, trophoblastic tumors, as well as congenital defects. Rarely, it can be elevated in  non-trophoblastic tumors such as squamous cell cancers and germ cell tumors. A 33-year-old Asian Syrian female had irregular menses accompanied with feelings of heaviness in the vagina. In additio...

Large polylactosaminoglycans have only been observed linked to membrane proteins. To determine if membrane anchoring of a secretory protein might lead to the addition of polylactosaminoglycan, we have examined the carbohydrate structure on a membrane-anchored form of human chorionic gonadotropin-alpha subunit. This protein was generated by fusing the DNA encoding the human chorionic gonadotropi...

IN 1906 Clevasseau classified tumours of the testis as teratomata, seminomata, interstitial cell tumours and adenomata. He noted the similarity between the seminoma and the epithelium of the seminal tubules, and considered that this type of tumour had its origin in the seminal epithelium. Nicholson (1907), Dew (1925), and Bell (1926) were in agreement with this theory. Since then numerous publi...

malignant neoplasms (MNP). The frequency of PNS in MNP ranges from 1 to 20 % according different authors. One the manifestations is acne, which occurs against background neoplasm due hormonal disorders. presented article describes a clinical case patient with mixed germ cell tumor and metastases retroperitoneal lymph nodes. produced human beta-chorionic gonadotropin, led development acne as PNS...

RATIONALE Psoas abscesses generally arise from a contiguous intra-abdominal or pelvic infectious process or hematogenous spreading of bacteria. The serum β-human chorionic gonadotropin has been used to detect normal or ectopic pregnancy. It also can be utilized in following up carcinomas. PATIENT CONCERNS Here, we reported a case of a 47-year-old woman who presented with a left psoas mass pre...

Background: To evaluate the effectiveness of intrauterine injection of recombinant human chorionic gonadotropin (rhCG) before embryo transfer (ET). Materials and Methods: In this randomized placebocontrolled clinical trial, a total number of 182 infertile patients undergoing their first in vitro fertilization/intracytoplasmic sperm injection (IVF-ICSI) were randomly assigned to receive 250 μg i...
