the purification of biomolecules is a necessary step in many biochemical researches. in this regard, developments of convenient, specific and low cost methods of purification are of particular interest. given the human hemoglobin (hb) affinity toward some charged carbohydrates, interaction of this molecule with human chorionic gonadotropin (hcg) which is a glycoprotein hormone containing sialic...

routinely, a bolus of 5.000-10.000 iu human chorionic gonadotropin (hcg) is usedfor the final follicular maturation and ovulation as a standard method. hcg has thesame effect of luteinizing hormone (lh) with long half-life. it has the longlutheotrophic effect which increases the risk of ovarian hyper stimulation syndrome(ohss). recently, gonadotropin-releasing hormone agonist (gnrh-a) trigger h...

placental site trophoblastic tumor (pstt) is the rare variant of gestational trophoblastic diseases (gtd), which differs histologically and immunologically from gtd. diagnosis of pstt is often difficult and delayed. in most cases, diagnosis is not possible until the surgery is performed. the most therapeutic choice is hysterectomy and it is usually successful. here we report two cases of pstt.

many findings point to the presence of a close relationship between the immune, endocrine and neurologic systems. for example the suppressive effects of β-human chorionic gonadotropin (β-hcg) on il-l production, the potentiative effect of enkephalins on lymphocyte functions and the suppressive effect of leuteinizing hormone (lh) on natural killer (nk) cell activities have been clearly establish...

Ectopic secretion of beta-human chorionic gonadotropin is considered a poor prognostic marker in epithelial tumors. However, very few cases have been reported in sarcomas. We present the case of a 26-year-old female who presented with a metastatic osteosarcoma. She underwent usual testing prior to starting treatment and was found to have elevated levels of beta-human chorionic gonadotropin. As ...

a highly sensitive electrochemicalimmunosensor was developed to detect hcg based on immobilization ofhcg-antibody (anti-hcg) onto robust nanocomposite containing gr, chit,1-methyl-3-octyl imidazolium tetra fluoro borate ionic liquid (il)(gr-il-chit). aunps were used to immobilize hcg antibody on the modifiedelectrode. the amine groups of the antibody are covalently attached toaunps/gr-il-chit n...

background and aims: some nanoparticles can be used in immunoassays to increase sensitivity. this study aimed to evaluate a novel nano-immunoassay based on bovine serum albumin nanoparticles (bsa nps). materials and methods: at first, the nanostructure was synthesized, and then applied as a tag in the nano-immunoassay. then the concentration of β-subunit of human chorionic gonadotropin (βhcg) i...

Through the use of immunohistochemical techniques, human chorionic gonadotropin has been localized to syncytiotrophoblastic cells of immature placenta, hydatidiform mole, chorioadenoma destruens, and choriocarcinoma. No gonadotropin has been detected in cytotrophoblast. Evidence is discussed which suggests that syncytiotrophoblast is the cell of origin of human chorionic gonadotropin. The obser...
