NPY and leptin receptor in the hypothalamus of rats with chronic immobilization stress

2013-07-24
(Press-News.org) A recent study entitled "Neuropeptide Y and leptin receptor expression in the hypothalamus of rats with chronic immobilization stress" showed that the body weight and food intake of rats subjected to chronic immobilization stress were significantly decreased; the expression of leptin receptor and the co-localization coeffient in these leptic receptor neurons in the arcuate nucleus of the hypothalamus were both upregulated, while the number of neuropeptide Y neurons was decreased. These findings which were in the Neural Regeneration Research (Vol. 8, No. 18, 2013) indicated that chronic immobilization stress induced high expression of leptin receptor in the arcuate nucleus and suppressed the synthesis and secretion of neuropeptide Y, thereby disrupting the pathways in the arcuate nucleus that regulate feeding behavior, resulting in diminished food intake and reduced body weight.

Male guppies ensure successful mating with genital claws

2013-07-24
TORONTO, ON – Some males will go to great lengths to pursue a female and take extreme measures to hold on once they find one that interests them, even if that affection is unrequited. New research from evolutionary biologists at the University of Toronto shows that the male guppy grows claws on its genitals to make it more difficult for unreceptive females to get away during mating. Genitalia differ greatly in animal groups, even among similar species – so much so that even closely related species may have very different genitalia. The reasons for these differences are ...

New study refutes existence and clinical potential of very small embryonic-like stem cells

2013-07-24
Scientists have reported that very small embryonic-like stem cells (VSELs), which can be isolated from blood or bone marrow rather than embryos, could represent an alternative to mouse and human embryonic stem cells for research and medicine. But their very existence is hotly debated, and a study appearing online on July 24th in the ISSCR's journal Stem Cell Reports, published by Cell Press, provides strong evidence against the existence of VSELs capable of turning into different cell types. The findings call into question current plans to launch a clinical trial aimed ...

A novel screening method makes it easier to diagnose and treat children with autism

2013-07-24
Researchers have developed a new screening method to diagnose autism, which unlike current methods does not rely on subjective criteria. These results are published in a series of studies in the open-access journal Frontiers in Neuroscience. The studies, funded by a US$ 650,000 grant from the National Science Foundation, were led by Elizabeth Torres, a computational neuroscientist, and Dimitri Metaxas, a computer scientist, both at Rutgers University, in collaboration with Jorge V. Jose, a theoretical physicist and computational neuroscientist from Indiana University. ...

Stanford scientists unable to find evidence of 'embryonic-like' cells in marrow of adult mice

2013-07-24
STANFORD, Calif. — Research on human embryonic stem cells has been a political and religious lightning rod for more than a decade. The cells long have been believed to be the only naturally occurring pluripotent cells. (Under the right conditions, pluripotent cells can become any other cell in the body.) But some people object to the fact that the embryo is destroyed during their isolation. Induced pluripotent stem cells, created by experimentally manipulating an adult cell such as a skin or nerve cell, are much more ethically palatable. But many researchers feel it is ...

Neural simulations hint at the origin of brain waves

2013-07-24
For almost a century, scientists have been studying brain waves to learn about mental health and the way we think. Yet the way billions of interconnected neurons work together to produce brain waves remains unknown. Now, scientists from EPFL's Blue Brain Project in Switzerland, at the core of the European Human Brain Project, and the Allen Institute for Brain Science in the United States, show in the July 24th edition of the journal Neuron how a complex computer model is providing a new tool to solve the mystery. The brain is composed of many different types of neurons, ...

Coastal Antarctic permafrost melting faster than expected

2013-07-24
For the first time, scientists have documented an acceleration in the melt rate of permafrost, or ground ice, in a section of Antarctica where the ice had been considered stable. The melt rates are comparable with the Arctic, where accelerated melting of permafrost has become a regularly recurring phenomenon, and the change could offer a preview of melting permafrost in other parts of a warming Antarctic continent. Tracking data from Garwood Valley in the McMurdo Dry Valleys region of Antarctica, Joseph Levy, a research associate at The University of Texas at Austin's ...

Want to stick with your diet? Better have someone hide the chocolate

2013-07-24
If you are trying to lose weight or save for the future, new research suggests avoiding temptation may increase your chances of success compared to relying on willpower alone. The study on self-control by researchers from the Universities of Cambridge and Dusseldorf was published today in the journal Neuron. The researchers compared the effectiveness of willpower versus voluntarily restricting access to temptations, called 'precommitment'. (Examples of precommitment include avoiding purchasing unhealthy food and putting money in savings accounts with hefty withdrawal ...

New study shows inbreeding in winter flounder in Long Island's bays

2013-07-24
STONY BROOK, NY, July 24, 2013–Research conducted in six bays of Long Island, NY, and led by scientists from the School of Marine and Atmospheric Sciences at Stony Brook University (SBU) showed that local populations of winter flounder are inbred, which is a situation that is not usually considered in marine fisheries management. The scientists also determined that the effective number of breeders in each bay was below 500 fish, suggesting that the spawning populations of this historically common fish are now relatively small in the area. "Severe inbreeding and small ...

Cognitive performance is better in girls whose walk to school lasts more than 15 minutes

2013-07-24
Cognitive performance of adolescent girls who walk to school is better than that of girls who travel by bus or car. Moreover, cognitive performance is also better in girls who take more than 15 minutes than in those who live closer and have a shorter walk to school. These are some of the conclusions of a study published in Archives of Pediatrics & Adolescent Medicine. The results come from findings of the nationwide AVENA (Food and Assessment of the NutritionalStatus of Spanish Adolescents) study, in which the University of Granada has participated together with the Autonomous ...

Trust in physician eases talks about medical expenses

2013-07-24
Strong relationships with physicians, particularly those that are long standing, are likely to increase patients' openness to talk about health care costs when decisions are being made about their treatment options. According to a new study1 by Marion Danis from the National Institutes of Health Clinical Center2 in the US, and colleagues, rushed visits with insufficient time to talk about important issues can undermine efforts to bring sensitive topics like costs into the doctor-patient relationship and can be counterproductive. The work appears online in the Journal of ...
