[Kenneth W McKerns] -- In September of scientists from many countries met at the Asticou Inn in Maine to present and discuss papers written especially for this monograph.
The presentations were informal and. For example, the nucleotide and the amino acid sequences of the gonadotropins from many species are now known and there is extensive information regarding the composition and structure of associated carbohydrate moieties .
Studies using deglycosylated hormones have played a critical role in the elucidation of the functional properties of Cited by: 4. Gonadotropins are protein hormones secreted by the pituitary gland and include luteinizing hormone (LH) and follicle stimulating hormone (FSH). Both LH and FSH govern the estrous cycle i.e.

These presentations reflected major advances from the in the understanding concepts offered at the last meeting. Other advances of hormone structure/function included the continuing work by Joyce Lustbader on the determination of the three-dimensional structure of hCG, including a new approach using nonisotopic labels for 3-D and 4-D NMR imaging.
Evolution of Gonadotropin Structure and Function 1. Publisher Summary. It has long been recognized that the control of gonadal function by pituitary hormones (gonadotropins) is a general feature of vertebrate reproductive physiology.
Numerous studies on the hormones of eutherian mammals have established the existence of two chemically Cited by: The book includes in vivo and in vitro studies on prostatic carcinoma and concludes with a chapter on functional and structural changes in male accessory sex organs during aging.
This book is invaluable to biomedical scientists, pathologists, and researchers interested in the biology and pathology of male accessory sex organs. Human Chorionic Gonadotropin  Introduction . Human Chorionic Gonadotropin (hCG) is a glycoprotein hormone made up of an alpha and beta subunit.
The alpha subunit making up hCG is the same one that makes up the alpha subunits of the luteinizing hormone, follicle-stimulating hormone, and thyroid-stimulating hormone. Unique for its role in human reproduction, a gamete is a specialized sex cell carrying 23 chromosomes—one half the number in body cells.
At fertilization, the chromosomes in one male gamete, called a sperm (or spermatozoon), combine with the chromosomes in one female gamete, called an oocyte. The function of the male reproductive system is to produce sperm.
Human endocrine system, group of ductless glands that regulate body processes by secreting chemical substances called hormones. Hormones act on nearby tissues or are carried in the bloodstream to act on specific target organs and distant tissues. Diseases of the endocrine system can result from the oversecretion or undersecretion of hormones or.
This book is a comprehensive, multi-authored work on the structure and function of the mammalian testis. The approach emphasizes gene expression, translation and production of specific gene products and the cellular and molecular regulation of these fundamental processes.
Rather than provide a global survey of all aspects of male reproduction, this book stresses 5/5(2). The pineal gland is an endocrine structure of the diencephalon of the brain, and is located inferior and posterior to the thalamus. It is made up of pinealocytes.
These cells produce and secrete the hormone melatonin in response to low light levels. High blood levels of. The book includes in vivo and in vitro studies on prostatic carcinoma and concludes with a chapter on functional and structural changes in male accessory sex organs during aging.

Human chorionic gonadotropin (hCG) is a hormone produced by the placenta after implantation. The presence of hCG is detected in some pregnancy tests (HCG pregnancy strip tests).Some cancerous tumors produce this hormone; therefore, elevated levels measured when the patient is not pregnant may lead to a cancer diagnosis and, if high enough, paraneoplastic syndromes.
The book begins by covering sexual dimorphism in the central nervous system; structure, control of secretion and function of GnRH; and gonadotropins of pituitary origin and their role in.
This book results from a study by a committee of the Institute of Medicine and the National Research Council's Board on Agriculture. The committee examined the scientific foundations of medically assisted conception and developed an agenda for basic research in reproductive and developmental biology that would contribute to advances in the clinical and agricultural.
GONADOTROPIN STRUCTURE AND FUNCTION. The three gonadotropins, follicle-stimulating hormone (FSH), luteinizing hormone (LH) and human chorionic gonadotropin (hCG), are glycoproteins composed of two non–covalently linked protein subunits, the alpha and beta subunits ().The alpha subunit contains 92 amino acids (AA) and is identical in FSH, LH, and by: A well-known example of the aging process affecting an endocrine gland is menopause and the decline of ovarian function.
With increasing age, the ovaries decrease in both size and weight and become progressively less sensitive to gonadotropins.

Throughout life, gonadotropins regulate reproductive function and, in the case of women, the onset and cessation of reproductive capacity. The gonadotropins include two glycoprotein hormones: follicle-stimulating hormone (FSH) stimulates the production and maturation of sex cells, or gametes, including ova in women and sperm in men.
The heart is one of the most vital and delicate organs in the body. If it does not function properly, all other organs – including the brain – begin to die from lack of oxygen within just a few minutes. As ofthe most common cause of death in the world was heart disease. Most heart disease occurs as a result of age or lifestyle.
To function properly, all contents of the plasma membrane must behave like a two-dimensional fluid, as described by the fluid mosaic model. In this model, the phospholipids, membrane proteins, and cholesterol molecules are constantly in motion as they maintain the bilayer structure, similar to the movement of sailboats bobbing in the ocean.
Hormonal Proteins and Peptides, Volume XI: Gonadotropic Hormones deals with gonad stimulating hormones that cause precocious sexual maturity. This book begins by reviewing the relationship of the chemical structure to the biological activity of gonadotropins and chorionic hormones, followed by a brief presentation on the in vitro bioassay methods.
A major aspect of reproductive capacity in women is its cyclical activity, a feature strikingly reflected in the growth and development of dominant follicles. Normally, the human ovaries produce a single dominant follicle that results in a single ovulation each menstrual cycle.
The dominant follicle is responsible for the production of estradiol during the follicular phase of the Cited by: A well-known example of the aging process affecting an endocrine gland is menopause and the decline of ovarian function.

Hypothalamic and pituitary hormones: The male body remains reproductively immature until the hypothalamus releases GnRH (Ganadotropin –releasing hormone), which stimulates the anterior pituitary gland to release gonadotropins (FSH, LH). FSH- stimulates Size: 1MB. Hormones have a wide range of effects and modulate many different body processes.
The key regulatory processes that will be examined here are those affecting the excretory system, the reproductive system, metabolism, blood calcium concentrations, growth, and the stress response.

Norethindrone is a synthetic progestational substance with some anabolic, estrogenic, and androgenic properties.
Norethindrone binds to the progesterone intracellular receptors in the reproductive system and the resultant activated complex interacts with specific DNA sites.
This leads to an alteration in protein synthesis and results in an inhibition of LH release. About this Item: Narosa Publishing House, Hardcover. Condition: New. Gonadal and Nongonadal Actions of Gonadotropins offers latest information on the structure and function of the gonadotropins, their signal transduction, and action at cellular and molecular levels.
As is true for most cells in the body, the structure of sperm cells speaks to their function. Sperm have a distinctive head, mid-piece, and tail region (Figure ). The head of the sperm contains the extremely compact haploid nucleus with very little cytoplasm.
