Show results in: Română

  • Endocrine Dysfunction

    No relationship between repeat size and inhibin concentrations in PMC.[mdpi.com] […] concentrations of total serum estradiol and serum estradiol not bound to sex hormone-binding globulin, (b) impaired spermatogenesis and sperm motility, and (c) blocking of multiple enzymes[ncbi.nlm.nih.gov] Typically, this may cause positive interference in competitive immunoassays (FT4 and FT3) and negative interference sandwich immunoassays (TSH).[endocrine-abstracts.org]

  • Granulosa Cell Tumor

    OBJECTIVE: Here, we report a case of secondary amenorrhea with low serum luteinizing hormone and follicle-stimulating hormone levels due to an inhibin A- and inhibin B-producing[ncbi.nlm.nih.gov] In addition it would open a new line of research with CYP17 enzyme inhibitors that could alter the course and outcome, usually fatal, in advanced stages of disease.[clinicaltrials.gov] The cohort of young women had expected normal values of AMH as measurable by the same immunoassay kit.[ncbi.nlm.nih.gov]

  • Aromatase Deficiency

    In normal girls, serum estradiol concentrations strongly correlate with circulating inhibin levels, and thus, low inhibin levels may contribute to the striking elevation of[ncbi.nlm.nih.gov] OBJECTIVE: Aromatase, or CYP19A1, is a type II cytochrome CYP450 enzyme that catalyzes the conversion of C19 androgens to C18 estrogens.[ncbi.nlm.nih.gov] As is the case with many immunoassays, heterophilic antibodies can cause false-positive results.[clinicaladvisor.com]

  • Congenital Adrenal Hyperplasia due to 21-Hydroxylase Deficiency

    In all children with TART, LH, FSH, testosterone and inhibin B levels were similar to the patients without TART.[ncbi.nlm.nih.gov] Short description: Congenital adrenogenital disorders assoc w enzyme deficiency The 2019 edition of ICD-10-CM E25.0 became effective on October 1, 2018.[icd10data.com] Traditional screening by enzyme immunoassay results in a large number of false positives.[ncbi.nlm.nih.gov]

  • HIV-2 Infection

    A & B Tumor Marker Chemistry 11/14/2017 Inhibin A Tumor Marker Chemistry 11/14/2017 Inhibin B Chemistry 12/20/2017 Inner Ear Antigen Serology 02/04/2016 Instructions for[childrensmn.org] From Wikipedia, the free encyclopedia Jump to navigation Jump to search HIV-2 retropepsin ( EC 3.4.23.47 ) is an enzyme . [1] [2] This enzyme catalyses the following chemical[en.wikipedia.org] The results of a commercial enzyme immunoassay specific for HIV-1 antibody were positive in both cases, but those of the Western blot technique were indeterminate.[ncbi.nlm.nih.gov]

  • Sertoli Cell-Only Syndrome

    RESULTS: All specimens showed intense staining for the inhibin alpha subunit. Moderate or intense staining for GDNF was observed in 65.8% of specimens.[ncbi.nlm.nih.gov] Deoxyribonucleic acid samples from controls and study subjects were digested with the restriction enzymes TaqI, EcoRI, and BamHI.[ncbi.nlm.nih.gov] An enzyme linked immunoassay for anti-Mullerian hormone: New tool for the evaluation of testicular function in infants and children.[ijem.in]

  • Granulosa Cell Tumor of the Ovary

    Her elevated serum FSH after the operation was the result of a decreased serum level of inhibin that had been produced by the tumor.[ncbi.nlm.nih.gov] Juvenile Granulosa Cell Tumors [ edit ] Two recent studies show that the enzyme AKT1 is involved in juvenile granulosa cell tumors.[en.wikipedia.org] The frequency of elevated levels varies amongst studies, likely due to the different specificities of the antibodies used in the immunoassays.[mayomedicallaboratories.com]

  • Sertoli Leydig Cell Tumor

    Early evaluation of the hypothalamic-pituitary-ovarian axis and inhibin levels is appropriate.[ncbi.nlm.nih.gov] For enzyme histochemical purposes the tumor tissue, removed from the right ovary by laparatomy, was frozen in liquid nitrogen.[ncbi.nlm.nih.gov] Estimation of androstenedione, by Radio-ImmunoAssay (RIA), showed a high value of 5.38 ng/ml (the normal value for adult female being 0.47-2.68 ng/ml.)[ispub.com]

  • Adrenogenital Syndrome

    In pubertal or postpubertal CAH patients, oligo or azoospermia may already be found due to obstruction of the seminiferous tubules Signs of gonadal dysfunction: decreased inhibin[pathologyoutlines.com] […] is affected by deficiency of a specific enzyme.[ncbi.nlm.nih.gov] The clinical manifestation of the disease is largely dependent on the type and degree of enzyme deficiency.[symptoma.com]

  • Epithelioid Trophoblastic Tumor

    The tumor cells were positive for cytokeratin, inhibin-alpha, and melanoma cell adhesion molecule (Mel-CAM, CD146) but were only focally positive for human placental lactogen[ncbi.nlm.nih.gov] […] specific enzymes produced more if the malignancy arises in organisms, so it can be used as a tumor marker . 1. prostatic acid phosphatase (PAP) is an enzyme produced by the[herryyudha.blogspot.com] However, light microscopic findings and immunohistochemical studies with pan-cytokeratin, epithelial membrane antigen, inhibin-alpha, beta-hCG, and human placental lactogen[ncbi.nlm.nih.gov]
