What's vasoactive intestinal polypeptide vip?

What's vasoactive intestinal polypeptide vip?

VIP definition: Vasoactive intestinal peptide or vip is a peptide hormone containing 28 Amino Acid residues. Vip is produced in many tissues of vertebrates including the gut, pancreas and suprachiasmatic nuclei of the hypothalamus in the brain. Vip stimulates contractility in the heart, causes vasodilation, increases glycogenolysis, lowers arterial blood pressure and relaxes the smooth muscle of trachea & stomach. Read more

Intestine (Definition)

The gastrointestinal tract starts at the mouth, travel down the tunnel (esophagus), which connects to the stomach, which then empties into the duodenum, jejunum, and ileum---the three parts of the small intestine (@25 feet). This empties into the colon or large intestine (about 5 feet), which then becomes the sigmoid colon, rectum and out the anus. So, every morsel eaten ...Read more

What does vasoactive intestinal peptide do?

What does vasoactive intestinal peptide do?

Messenger proteins: These proteins are released by nerve endings in the intestines. They can cause the muscle walls of organs and blood vessels to relax. For example, they help the muscle band in the lower esophagus to open up and pass food into the stomach, and can increase blood flow in the intestines. They also stimulate secretions. Tumors that produce large amounts of vip cause severe diarrhea. Read more

Does vip (vasoactive intestinal peptides) have to be out on ice imediately. If done incorrect would you get false high or low?

Does vip (vasoactive intestinal peptides) have to be out on ice imediately. If done incorrect would you get false high or low?

If it's going to be: Stored it needs to be kept on ice then frozen. However, once the blood is drawn, it is always better for it to be put on ice. What actually disturbs the results, could be the technique used in the washing, essentially the "lab" section. Most of the time the lab techs have done this for years and are capable of producing good results. If you are not satisfied, have it repeated. Read more

How high must vasoactive intestinal levels be to indicate a disease process?

How high must vasoactive intestinal levels be to indicate a disease process?

>75: The diagnosis of a vipoma is established by the presence of an otherwise unexplained high volume secretory diarrhea and a serum vip concentration in excess of 75 pg/ml. A single elevated vip level should be confirmed by additional testing. Read more

Elevated vasoactive intestinal peptides chromogranin & 5-hiaa. Could these tests be linked? Or is one incorrect. Hypokalemia and dehydration.

Elevated vasoactive intestinal peptides chromogranin & 5-hiaa. Could these tests be linked? Or is one incorrect. Hypokalemia and dehydration.

Can be linked: Neuroendocrine tumor in the intestine can produce all these abnormalities. Such tumors may be small and non-malignant but can still cause considerable morbidity. It may require you to consult both a GI specialist and an endocrinologist to sort things out. Read more

Is insulin a polypeptide or a protein?

Is insulin a polypeptide or a protein?

Definition: Hi. A definition was decided arbitrarily long ago, in the infancy of biochemistry, that proteins are 50 or more amino acids, and polypeptides are 49 or fewer. Insulin is a 51 amino acid polypeptide, and therefore, a protein. But it's completely arbitrary, and the chemistry of insulin doesn't care if you call it a protein or a polypeptide. But insulin rocks, eh?! Read more

What are the benefits of taking collagen capsules? 4 capsules daily. Hydrolyzed marine collagen and elastin polypeptides.

What are the benefits of taking collagen capsules? 4 capsules daily. Hydrolyzed marine collagen and elastin polypeptides.

Not much evidence: There aren't a lot of studies out that have tested the health effects of all these collegen supplements.One study found that it does not really help with bone health, and another showed some preservation of lean body mass in older women but no skin improvement. It seems that elastin skin products have not shown clinically to improve elasticity of the skin but do help the skin hold moisture. Read more

How accurate is pancreatic polypeptide In detecting pancreas tumor?

How accurate is pancreatic polypeptide In detecting pancreas tumor?

NOT VERY!!!: Hi. Pancreatic polypeptide (PP) is NOT a screening test for pancreatic tumors. The only pancreatic cells that make PP are rare neuroendocrine cells in the Islets of Langerhans (an already tiny fraction of the pancreas). And those would be a TINY, TINY fraction of all pancreatic tumors. But hey, if it's a PP secreting neuroendocrine tumor of the pancreas, you'd have it dialed! Good luck! Read more

Can you tell me how the hbs polypeptide reduce oxygen transport in sickle cell disease?

Can you tell me how the hbs polypeptide reduce oxygen transport in sickle cell disease?

Some info: Hemolobin S produces what are known as hemoglobin tactoids-gelations of hemoglobin which are not as able to release oxygen because of mechanical reasons. Read more

DERMATOLOGISTS: Will taking collagen capsules help with fine lines over time? Ingredients:hydrolyzed marine collagen, elastin polypeptides

I really doubt it.: Protein is digested and absorbed. It's doubtful that a small amount of a particular protein is going to be 'special' compared to a burger.
Less collagen, degraded protein loss of subcutaneous fat are aging features that promote crow's feet and specific dietary proteins just aren't going to change any of that. Read more

I have primary hyperparathyroidism. My lipase and amylasec ranges from borderline high to x 6 u.L. Since 2006. The pancreatic polypeptide was x 3 u.L. In 2013. The CT wasnormal. Could I have neuroendocrine tumor or men-1?

I have primary hyperparathyroidism. My lipase and amylasec ranges from borderline high to x 6 u.L. Since 2006. The pancreatic polypeptide was x 3 u.L. In 2013. The CT wasnormal. Could I have neuroendocrine tumor or men-1?

Not unlikely: Neuroendocrine tumors can be difficult to detect. If the symptoms persist or worsen, there are more sophisticated imaging modalities available to look for occult tumors, including gallium 68. If you have other family members who have been diagnosed with pancreatic or adrenal tumors and/or hyperparathyroidism, men1 would be possible. Read more

What can cause intestinal failure?

What can cause intestinal failure?

Insufficient length: We consider intestinal failure the need to permanently provide another means of nutrition, because the intestines don't provide sufficient intake to support survival. This occurs when the small intestine has been operated on because of trauma, or because of obstruction, or because of infection, etc. Tpn (total parenteral nutrition) provides nutrition by vein. Small bowel transplant may be possible. Read more
