Drinkers 'ignorant of sleep woes' Aug 19, 2009
Alcohol stops the brain from releasing vasopressin, a chemical which tells the kidneys to reabsorb water that would otherwise end up in the bladder. Without this signal, the drinker needs more frequent trips to the toilet. (BBC News -- UK)
Receptor Also Active Inside The Cell Aug 4, 2009
The most common cause of the inheritable form of nephrogenic diabetes insipidus (NDI) are errors in the gene that encodes the vasopressin receptor, leading to absence of this receptor at the cell surface and making it unable to bind its hormone vasopressin. Vasopressin transmits signals from the brain to the kidney to induce water uptake from the pro-urine ... Kidney cells of NDI patients do produce vasopressin receptors, but as these have a disturbed structure, they remain trapped inside the... (Science Daily)
Diabetes in Dogs Jul 19, 2009
Diabetes insipidus is caused by lack of vasopressin, an anti-diuretic hormone that controls water resorption by the kidneys. Diabetes mellitus is the most common type in dogs. (Suite101.com)
Therapy Helps Improve Outcomes For Patients With Severe Sepsis Jun 19, 2009
14, 2007) Vasopressin should be used with great caution for the treatment of hypotension in septic shock, according to new results. The experiments -- conducted in pigs -- show it can significantly reduce. (Science Daily)
Can science tell us why we fall in love? Jun 16, 2009
"But in contrast to those newly in love," says Acevedo, other brain regions did, too, including areas rich in oxytocin, vasopressin (a similar chemical) and serotonin, a brain chemical associated with well-being and calmness. The link between long-term attachment and oxytocin has long fascinated researchers, among them, Sue Carter, a neuroendocrinologist at the University of Illinois in Chicago. (Boston Globe)
Gene Test Determines Risk Of Heart Surgery Complications May 8, 2009
Therefore, the researchers suggest that "perhaps, more suitable hemodynamics could be achieved in LL patients were they given vasopressin rather than noradrenaline (norepinephrine) and acute kidney injury might be attenuated by avoidance of cardiopulmonary bypass and nephrotoxic medication." Larger clinical trials are necessary to show whether patients need to undergo genetic testing prior to heart surgery to determine their risk for shock and kidney failure. Journal reference.

The pain (and healing) of a broken heart Apr 20, 2009
From there, dopamine travels to your prefrontal cortex and cingulate cortex, where it joins its cousin chemical, norepinephrine, to create a "lover's high." Couple this hit with the warm feelings created when your hypothalamus secretes oxytocin and vasopressin, and you have the recipe for a full-blown addiction ... Attachment is not an all-or-nothing proposition, but a gradual process that appears to be likely facilitated by two other hormones that flood the brain during intimacy: oxytocin,... (MSNBC -- Health)
Men's Health Identifies Five Paths ... Apr 10, 2009
Men who are more likely to stray may not be as affectionate as their partners would like, Cleaver says, due to a variation of a gene that controls the release of the hormone vasopressin ... Activities like creating opportunities for intimacy and having sex may increase vasopressin and encourage bonding in married couples. (Suite101.com)

Hospital to award Lindheimer for research that aids mothers, infants Mar 6, 2009
Working with John Davison, of Newcastle upon Tyne University, England, Lindheimer mapped out how regulation of the hormone vasopressin affected fluid retention during pregnancy. Understanding this process led them to predict the existence of an as-yet-unrecognized disease, now known as transient diabetes insipidus during pregnancy. (Univeristy of Chicago Chronicle, IL)
Cupid's Arrow May Cause More Than Just Sparks To Fly This Valentine's Day Feb 15, 2009

This Valentine's Day, say it with brain chemicals Feb 13, 2009
In males it is vasopressin. Young put vasopressin receptors into the brains of meadow voles - a promiscuous cousin of the prairie voles - and "those guys who should never, ever bond with a female bonded with a female.". (Honolulu Star-Bulletin)
A potion for emotions? Maybe someday Feb 13, 2009
The hormones vasopressin and oxytocin loom large in his studies ... In male prairie voles, vasopressin switches on the vole equivalent of giving up your cushy job in Miami to be closer to a woman in Manitoba, getting into bar fights when some guy looks at her, and coaching all of juniors hockey games like the doting father you have become ...

2 genes influence social behavior, visual-spatial performance in people with Williams syndrome Feb 12, 2009
Endowed with the power to control the activity of other genes, GTF2I might regulate signal pathways determining the structure and function of the brain or the production of neurohormones such as vasopressin and oxytoxin. Oxytoxin plays a key role in the desire to seek social interactions and trusting others, which might explain why for children with Williams syndrome, the world has no strangers, only friends.

Brains have a love circuit Feb 12, 2009
In males, it's vasopressin. Young put vasopressin receptors into the brains of meadow voles a promiscuous cousin of the prairie voles and "those guys who should never, ever bond with a female, bonded with a female.'' Researchers also uncovered a genetic variation in a few male prairie voles that are not monogamous and found it in some human males, too. Those men with the variation ranked lower on an emotional bonding scale, reported more marital problems, and their wives had more concerns about... (India Times, India -- Health/Science)
