Recent Progress in Hormone Research, Volume 42 covers the proceedings of the Laurentian Hormone Conference held on September 1985 in Banff, Alberta, Canada. The book presents developments in research on important topics such as chemical neuroanatomy of the brain based on the histochemistry of brain neuronal transmitters and peptides; the hormonal regulation of gene transcription and expression; and steroid hormone receptors and their action. The text also includes papers on the atrial naturietic factor; the fibroblast growth factor; and the neuroendocrinology of puberty in rodents, seasonal breeders, and humans. Papers on the comparative endocrinology including studies on marsupials, teleosts, and microorganisms; and parathyroid hormone, bioactive forms, gene expression, and malignancy-associated hypercalcemia are also encompassed. Endocrinologists, physiologists, biochemists, and scientists involved in hormone research will find the book invaluable.
