From A Textbook of Modern Toxicology, 3rd ed., ed. E. Hodgson. New York: Wiley, the formation of a colored insoluble product of an enzymatic reaction, the enzyme, such as alkaline phosphatase or horseradish peroxidase, being covalently linked to the secondary antibody.   Handbook of Biologically Active Peptides, Second Edition, is the definitive, indispensable reference for peptide researchers, biochemists, cell and molecular biologists, neuroscientists, pharmacologists, and endocrinologists. Its chapters are designed to be a source for workers in the field and enable researchers working in a specific area to examine related areas outside their Edition: 2.

Intravenous administration of mcg gonadotropin releasing hormone (GnRH) results in much more substantial rise in free alpha-subunit levels in CDP patients, compared with HH patients. A >6-fold rise at 30 or 60 minutes post-injection is seen in >75% of CDP patients, while a pg/mL) and relatively low aluminum ( mcg/mL.   The invention provides human secreted proteins (SECP) and polynucleotides which identify and encode SECP. The invention also provides expression vectors, host cells, antibodies, agonists, and antagonists. The invention also provides methods for diagnosing, treating, or preventing disorders associated with aberrant expression of SECP.

  In some aspects, the invention relates to Heat Shock Protein-1 (HSF1) gene and HSF1 gene products. In some aspects, the invention provides methods of tumor diagnosis, prognosis, treatment-specific prediction, or treatment selection, the methods comprising assessing the level of HSF1 expression or HSF1 activation in a sample obtained from the tumor. Gonadotropin-releasing hormone (GnRH) neurons, a small number of cells scattered in the hypothalamus, play an important role in reproduction. During development, GnRH-neurons are born in the olfactory placode and migrate along olfactory nerves (vomeronasal and terminal) in the nasal compartment (NC) to gain access into the forebrain (FB) and.

Gonadotropin releasing hormone (GnRH) analogs can cause regression of hormone‐dependent breast carcinomas via the specific GnRH receptor (GnRH‐R). In an attempt to obtain a better understanding of GnRH actions in human breast carcinoma, the expression of GnRH‐R was examined immunohistochemically in 58 invasive ductal carcinomas and Cited by: The distribution of serotonin-immunoreactive (5-HT-ir) and gonadotropin-releasing hormone-immunoreactive (GnRH-ir) elements in the brain and pituitary gland of the Atlantic croaker (Micropogonias undulatus) was studied using immunoperoxidase and immunofluorescence techniques.

Successful reproduction requires maintenance of the reproductive axis within fine operating limits through negative feedback actions of sex steroids.
