There are many set points of different measures of the body that either genetically coded (like body temperature), or dictated by the surrounding environment (like stress). These set points are present in a part of our brain called Hypothalamus. One of the major functions of the hypothalamus is to regulate secretion of endocrine hormones directly into the blood. Hormones and nerves form the 2 regulatory mechanisms of the body ...

The proliferative response of non-β islet endocrine cells in response to type 1 diabetes (T1D) remains undefined. We quantified islet endocrine cell proliferation in a large collection of non-diabetic control and T1D human pancreata across a wide range of ages. Surprisingly, islet endocrine cells with abundant proliferation were present in many adolescent and young adult T1D pancreata. But, the proliferative islet endocrine cells were also present in similar abundance within control samples. We queried the proliferating islet cells with antisera against various islet hormones. Although PP, somatostatin, and ghrelin cells did not exhibit frequent proliferation, glucagon-expressing α-cells were highly proliferative in many adolescent and young adult samples. Notably, α-cells only comprised a fraction (∼1/3) of the proliferative islet cells within those samples; most proliferative cells did not express islet hormones. The proliferative hormone negative cells uniformly contained ...

The diagnosis of SPT is made based on the clinical presentation, location of tumor, histological findings, and immunohistochemical staining. SPTs express positive immunohistochemical staining for vimentin, CD56, alpha-1-antitrypsin and neuron-specific enolase. Epithelial markers (keratins) may be focal or weakly positive. Synaptophysin is commonly positive in SPTs; however, chromogranin is usually negative. Immunohistochemical staining for Amylase/Lipase/Trypsin are negative, as well as those for pancreatic hormones. There may be positive immunohistochemical staining for CD10, Beta- catenin, CD117 (c-kit), Progesterone receptor, and the beta form of estrogen receptor. SPTs are considered to be tumors of low malignant potential and more than 80% of SPTs are cured by surgical resection. However, metastases may be seen in a small percentage of patients. When metastasis occurs, it is usually to the liver or peritoneum. Patient follow-up: The patient underwent a brain biopsy. Histologic examination ...
Scientists of Helmholtz Zentrum München and Technical University of Munich have developed a smart drug that safely clears the liver of fat and prevents blood vessels from clogging up. Similar to a trojan horse, the drug enters the liver with a trick: It uses the pancreatic hormone glucagon as vehicle to shuttle thyroid hormone T3 the live while keeping it away from other organs, thereby improving cholesterol and lipid metabolism while avoiding typical side effects of thyroid hormone.
As understanding the role of cell cycle proteins in the specification of endocrine cells from pancreatic progenitors is essential to developing methods of β-cell regeneration, we began by analyzing the role of p27 during pancreatic development. The major mechanism for regulating p27 levels is thought to be posttranslational proteolytic degradation, as the mRNA levels of p27 are constant throughout the cell cycle (18,19). The cellular distribution of p27 protein was examined by performing immunohistochemistry on pancreatic sections from various embryonic stages. The p27 protein was confined to the nucleus of epithelial cells and absent from the mesenchyme during early stages of pancreatic bud formation. Costaining with endocrine hormones at embryonic day 11.5 revealed that p27 was present in the nucleus of glucagon-expressing cells (Fig. 1A). To assess whether p27 is expressed in other endocrine cells, we examined the pancreatic epithelium for the expression of insulin and p27 at embryonic day ...
This is an important distinction, so were gonna talk about the endocrine system, well talk about some exocrine stuff in GI. But exocrine stuff travels through ducts in the body, like through our GI tract and other ducts within the body, and they exert their influence close to where they are released. Versus endocrine hormones, which travel in the body through the blood, and go travel long distances to exert an influence off of ROA, and obviously, thats relative. ...
Human growth hormone (HGH) is one of many of endocrine hormones such as testosterone, estrogen, melatonin, and DHEA, which decline in production with age. While some of these hormones can reduce the effects of aging, only HGH and IGF-1 (IGF=insulin growth factor) go far beyond the scope of the other hormones not only to prevent biological aging but also to reverse a broad range of symptoms associated with aging and even certain diseases of aging. So if you are interested in increasing endurance and turning back the aging clock by 20 or more years, be ye young or be ye old, HGH and IGF-1 are the secret of the fountain of youth, potent anti-aging medicine ...

The thyroid is a butterfly-shaped endocrine (hormone secreting) gland in the neck that is found on both sides of the trachea (windpipe). It secretes the hormone Thyroxine which controls the rate of metabolism.
Scientists measured 26 chemicals in the blood and urine of 718 mothers during the first trimester of their pregnancies in the study of Swedish mothers and children, known as SELMA. These chemicals included bisphenol A (BPA), which is found in plastic food and drink containers, as well as pesticides, phthalates, and other chemicals found in consumer products. Some of the 26 are known to disrupt endocrine (hormone) activity in humans; others have been shown to do so only in animals, or are suspected of endocrine disruption because they share chemical features with known disruptors. ...
This test measures a substance in your blood called pancreatic polypeptide. Higher levels may mean you have a type of pancreatic tumor.
The effect on GH secretion of GH-releasing factor (GRF), a 44-amino acid peptide recently isolated from a human pancreatic tumor (hpGRF), was examined in conscious male rabbits. During a 6-h period (1030-1630 h) of the control study individual rabbits exhibited pulsatile GH release with a surge at 1030-1200 h, a trough at 1200-1400 h, and a second peak at 1400-1630 h. Intravenous bolus injections of 1 and 10 micrograms hpGRF caused significant and dose-related increases in plasma GH during both the period of the trough (1300 h) and the surge (1530 h), although the GH responses were obviously higher during the latter than the former period. Passive immunization with anti-somatostatin (SRIF) sheep serum resulted in a prompt increase in plasma GH immediately after an injection of the antiserum. When 0.1, 1, and 10 micrograms hpGRF were successively injected iv at 1215, 1345, and 1515 h, respectively, maximum levels of plasma GH after hpGRF in anti-SRIF sheep serum-treated rabbits were significantly higher
Human growth hormone (or HGH) is a member of a family of endocrine hormones. This family includes hormones such as testosterone, estrogen, melatonin and DHEA. Production of HGH and other hormones decreases with age. While all these hormones have anti-aging effects, only HGH go far beyond the reach of other hormones to prevent biological aging and also revert to a wide range of aging symptoms and even some aging diseases. HGH is known to be the most abundant endocrine hormone produced by the pituitary gland. Growth hormone is secreted at a rate that reaches a maximum during the mid-twenties, when a young person develops. The decline in the production of human growth hormone is directly associated with some signs of aging such as wrinkles , hair aging , decreased energy and sex, erectile dysfunction in men and menopause in men Women, an increase in body fat, heart disease and blood pressure problems, fragile and brittle bones and much more. Although HGH cannot completely stop the aging process, ...
Assays for the pancreatic hormone glucagon have typically been carried out using RIAs, but specificity has always been a problem, as the same amino acid sequence is present in other endogenous peptides in addition to glucagon, as discussed in the Introduction. Sensitivity (i.e. the smallest concentration of a substance that can be reliably measured) is also a prominent issue, as circulating concentrations are likely to be low, around 10 pmol/l or less (22). The relevant changes in glucagon secretion, resulting from changes in plasma glucose concentrations, are also modest with increases in response to hypoglycaemia ranging from 20 to 30 pmol/l, but even more challenging are decreases in response to hyperglycaemia, which may lower the concentrations to 1-2 pmol/l (24). Clearly, assays with sensitivities ,5 pmol/l are, therefore, unsuitable for the complete characterisation of glucagon secretion. The present study demonstrates that it is important to test a commercial assay carefully before being ...
After removal of the pancreas pigs develop hyperglycaemia and ketosis. Both orthotopic and heterotopic transplants prevent hyperglycaemia but the animals so treated display markedly different patterns of glucose and insulin metabolism. Orthotopic graft recipients have normal glucose tolerance curves with raised plasma insulin levels. The glucose tolerance curves of heterotopic graft recipients show significant hypoglycaemia and very marked hyperinsulinaemia. These results are explicable by the diversion of the two pancreatic hormones from the liver, and possibly by the effect of ischaemia and denervation on the pancreas.. ...
Glucagon is an essential pancreatic hormone that raises the blood sugar level. Glucagon administration is sometimes required to treat hypoglycemia in diabetes.
MODEL RELEASED. Insulin injection. Overweight diabetic man injecting himself in the abdomen with insulin. He has diabetes mellitus. This is a disorder affecting glucose sugar metabolism. Sugar is not oxidised due to a lack of the pancreatic hormone insulin. Unused sugar accumulates in the blood and the urine. Fats are used as an alternative energy source, which leads to a build-up of ketones in the blood. This build-up may eventually cause convulsions and diabetic coma. Treatment is based on a strict diet and the use of daily insulin injections to maintain the blood-sugar balance. - Stock Image M725/0419
Insulin and lipoprotein lipase work together in your body to use extra calories from carbohydrates in your diet to make and store fats. Insulin is a pancreatic hormone that is commonly known to regulate your blood sugar level, but it also regulates the production of fats from carbohydrates.

Due to its chemical structure, olive oil is of unrivaled organoleptic value and thus the oil best suited for human consumption. It is very well tolerated by the stomach. In fact, its protective function has a beneficial effect on gastritis and ulcers. It is a cholagogue, activating the secretion of pancreatic hormones and bile much more naturally than prescribed drugs. Consequently, it lowers the incidence of cholelithiasis (gallstone formation). Its excellent digestibility promotes the overall absorption of nutrients, especially vitamins and mineral salts. It has a positive effect on constipation. Bones need a large amount of oleates and what source could be better than olive oil? Promoting bone mineralisation, it is excellent for infants and the elderly who have bone calcification problems. It also has beneficial effects on brain and nervous system development as well as on overall growth. It shields the body against infection and helps in the healing of tissues, internal and external. Olive ...

Normal tissue growth involves a complex interaction of cell proliferation, hypertrophy, migration, differentiation and senescence which proceeds within strict temporal and anatomical constraints. While classical endocrine hormones such as growth hormone and thyroxine can influence the overall rate of growth and maturation they do not contribute to the fundamental intercellular signalling within tissues that underlies these processes. This appears to be the primary role of peptide growth factors. During the rapid development of the embryo and fetus peptide growth factors are associated with tissue induction, the clonal growth of stem-cell populations, and the appearance of differentiated function in the presumptive organs. In post-natal life the actions of growth factors are less obvious although notable exceptions demonstrate that the same biological pathways exist; the best studied examples are the role of somatomedins during longitudinal skeletal growth and the coordinated actions of several growth
Hormones and pheromones: Internal and external control of animal behaviors. We focus on the mouse vomeronasal sensory system that detects and discriminates specific molecular cues provided as pheromones. Neurons in the brain that respond to pheromone signals express a variety of hormone receptors, suggesting a potential mechanistic link between the pheromone-processing circuitry and endocrine hormones. Using an in vitro cell culture system and in vivo mouse models, our lab aims to elucidate how the brain controls behavior through integration of external sensory signals and internal hormonal state.. ...
Essential fatty acids are necessary for various aspects of normal physiology like: mediating immune response, regulating bodily secretions and their viscosity, dilating and constricting blood vessels, regulating collateral circulation, directing endocrine hormones to their target cells, regulating smooth muscles and autonomic reflexes, being primary constituents of cell membranes, regulating the rate of cell division, maintaining the fluidity and rigidity of cellular membranes, regulating the flow of substances into and out from cells, transporting oxygen from red blood cells to the tissues, maintaining proper kidney function and fluid balance, keeping saturated fats mobile in the bloodstream, preventing blood clots, mediating the release of inflammatory eicosanoids that may trigger allergic conditions, and regulating nerve transmission and communication.

By Dr. Ilya Sandra Perlingieri. Global Research. May 12, 2010. www.globalresearch.ca/index.php?context=va&aid=19047. For decades, we have known that heavy metals and chemicals can cause grave physical harm. Going back to Rachel Carsons "Silent Spring," we have known and been amply warned of the serious consequences of using or being exposed to these poisons in our daily activities. Thousands of these are well-documented carcinogens.. Building on Carsons ground-breaking research, we also know that certain kinds of chemicals can and do disrupt human [and other animals] entire immune system. Going back 30 years, researchers were investigating what became known as endocrine [hormone] disrupting chemicals and how they were affecting frogs [who sometimes had five legs or hermaphroditic characteristics], other aquatic animals, and mammals. These animals were the proverbial canaries in the coal mine.. In another pioneering book, "Our Stolen Future," authors Dr. Theo Colburn, Dianne Dumanoski, and ...

Postprandial gut hormone responses change after Roux-en-Y gastric bypass (RYGB), and we investigated the impact of glucose, protein, and fat (with and without pancreas lipase inhibition) on plasma responses of gut and pancreas hormones, bile acids, and fibroblast growth factor 21 (FGF-21) after RYGB and in nonoperated control subjects. In a randomized, crossover study 10 RYGB operated and 8 healthy weight-matched control subjects were administered 4 different 4-h isocaloric (200 kcal) liquid meal tests containing ,90 energy (E)% of either glucose, protein (whey protein), or fat (butter with and without orlistat). The primary outcome was glucagon-like peptide-1 (GLP-1) secretion (area under the curve above baseline). Secondary outcomes included responses of peptide YY (PYY), glucose-dependent insulinotropic polypeptide (GIP), cholecystokinin (CCK), glicentin, neurotensin, ghrelin, insulin, glucagon, bile acids, and FGF-21. In the RYGB group the responses of GLP-1, GIP, glicentin, FGF-21, and ...

N2 - Recent reports have suggested that mesenchymal cells derived from bone marrow may differentiate into not only mesenchymal lineage cells but also other lineage cells. There is possibility for insulin-producing cells (IPCs) to be differentiated from mesenchymal cells. We used self-functional repair stimuli of stem cells by partial injury. Rat pancreatic extract (RPE) from the regenerating pancreas (2 days after 60% pancreatectomy) was treated to rat mesenchymal cells. After the treatment of RPE, they made clusters like islet of Langerhans within a week and expressed four pancreatic endocrine hormones; insulin, glucagon, pancreatic polypeptide, and somatostatin. Moreover, IPCs released insulin in response to ...
The human body wants blood glucose (blood sugar) maintained in a very narrow range. Insulin and glucagon are the hormones which make this happen. Both insulin and glucagon are secreted from the pancreas, and thus are referred to as pancreatic endocrine hormones. The picture on the left shows the intimate relationship both insulin and glucagon have to each other. Note that the pancreas serves as the central player in this scheme. It is the production of insulin and glucagon by the pancreas which ultimately determines if a patient has diabetes, hypoglycemia, or some other sugar problem. Insulin and glucagon are hormones secreted by islet cells within the pancreas (more about islet cells of the pancreas). They are both secreted in response to blood sugar levels, but in opposite fashion! Insulin is normally secreted by the beta cells (a type of islet cells) of the pancreas. The stimulus for insulin secretion is a HIGH blood glucose...its as simple as that! Although there is always a low level of ...
Four years ago, the research team of Pedro Herrera (University of Geneva) first cast doubt on this assumption when they demonstrated that a few alpha cells in the pancreas of genetically modified diabetic mice changed into beta cells. Alpha cells normally produce the blood sugar-raising hormone glucagon, but in diabetic mice they started producing insulin instead. Herreras team has now made a second discovery, which has just been published in the journal Nature (*): in prepubescent mice the pancreas is capable of compensating the loss of insulin-producing beta cells. This is achieved by a mechanism unknown until now, says Herrera. The process involves the reversion of delta cells (which produce somatostatin, another pancreatic hormone) to a precursor-like cell state, with proliferation and later reconstitution of the populations of beta and delta cells ...
MODEL RELEASED. Education for diabetes. Elderly diabetic man and his family receive instruction by a hospital nurse (at centre) on how to inject insulin. Diabetes mellitus is a carbohydrate metabolism disorder. It is a disease in which sugars in the body are not oxidised to produce energy due to a lack of the pancreatic hormone insulin. Unused sugars thus accumulate in the blood and the urine. And fats which are used as an alternative energy source lead to a build-up of ketones in the blood that may cause convulsions and diabetic coma. Treatment is based on a strict diet and the use of daily insulin injections to maintain the blood-sugar balance. - Stock Image M725/0207
The pancreas is a large gland, situated in the peritoneal cavity, in the curve of the duodenum. It is the pancreas that is responsible for aiding the bodys endocrine system. (Darlington College 2011). The pancreas releases two endocrine hormones and it is these hormones that ensure the blood glucose levels within the body are constantly controlled. These hormones are glucagon and insulin and they are secreted from tiny clusters of cells within the pancreas, know as the islets of Langerhans. Glucagon is a hyper- glycaemic hormone, secreted by the islets alpha cells. Its main function is to increase the level of glucose in the blood. This is a vital process when blood sugar levels become low. Glucagon stimulates the liver to break down its excess glycogen into glucose. The glucose then passes into the blood stream and the homeostasis of blood glucose level is restored. Insulin is a hypo- glycaemic hormone that is secreted by the islets beta cells, in response to high blood glucose levels. Insulin ...
