Depression gene may weaken mood-regulating circuit

...as been linked to anxious temperament. Yet, how it works at the level of brain circuitry remained a mystery. The NIMH research team first scanned 114 healthy subjects using magnetic resonance imaging (MRI). Those with at least one copy of the short variant had less gray matter, neurons and their connectio...

New method shows it is possible to grow bone for grafts within a patient's body

...rious spinal injuries and back pain. Although this works well at the repair site, the removal operation is extremely painful and can produce serious complications. If the new method is confirmed in clinical studies, it will become possible to grow new bone for all types of repairs instead of removing it fr...

Researchers find first evidence of venom system in extinct mammal

...y systems than previously believed," said Fox, who works out of the Laboratory for Vertebrate Paleontology in the U of A Department of Biological Sciences. About the size of a mouse, the ancient mammal--Bisonalveus browni--may have resembled a small hedgehog or a small mole, but it isn't related to any an...

Caloric restriction won't dramatically extend life span in humans: UCLA research

...und in fish, spiders and many other species. If it works for them, some thought, it should work for us; I'm... 10 years ago on caloric restriction and on why it works in extending the lives of rodents. "When you restrict the caloric intake of rodents, the first thin...

Scripps research scientists solve structure of a critical innate immune system protein

... flies. Broadly speaking, the innate immune system works something like this. Certain cells have the ability to recognize foreign molecules such as components of membrane like LPS or other protein molecules unique to microorganisms . The presence of these pathogen-specific molecules activates the immune sy...

Green catalyst destroys pesticides and munitions toxins, finds Carnegie Mellon University

...tely destroying these compounds," said Chanda, who works in the laboratory of Terrence Collins, the Thomas ... (TAML stands for tetra-amido macrocyclic ligand), works with hydrogen peroxide. Its "green" design is based on elements used naturally in biochemistry. Fe-T...

Unexpected lock and key mechanism found for the assembly of tumor blood vessels

...enesis. It's possible that since the integrin only works on developing blood vessels and in cancer, disrupting its ability to form blood vessels could starve the tumor and stave off cancer." The research team discovered that the integrin brought the endothelia, the inside part of a blood vessel, together ...

Compound might defeat African sleeping sickness, clinical trial beginning this month

...nal brain stage," the physician said. "When a drug works and helps a lot of people, that's when all our hard work really pays off, and we can be proud of our efforts." Three years ago, the National Foundation for Infectious Diseases presented its Jimmy and Roselyn Carter Humanitarian Award to Bill and Mel...

Scientists find that protein controls aging by controlling insulin

... discovered that a protein prolonging life in mice works by controlling insulin. The protein, Klotho, is found in several species. In mice, the researchers discovered, it acts as a hormone, circulating through the blood and binding to cells. Therapies based on this hormone could prove to be a way to ext...

USC researchers determine mechanism of action of chemotherapy drug

...ame: Xcytrin, manufactured by Pharmacyclics, Inc.) works to thwart cancer cells by disrupting key enzymes involved in cellular metabolism, according to a team of researchers led by Joseph Hacia, Ph.D., assistant professor of biochemistry and molecular biology at the Keck School of Medicine of the Universit...

Fragment of yellow fever virus may hold key to safer vaccine

...s so effective," ter Meulen said. "Medical science works in cycles. As soon as the problem is solved, the caravan moves on. Once the disease comes back, people realize they are lacking certain information." To learn more about the immune response and to identify the necessary components of an improved vac...

Snapin: A protein with therapy potential for autism

...du/medrel/viewArticle.html?ArticleID=3708 ). Cypin works on tubulin, a protein that is a structural building block of the dendrite skeleton. Now Firestein's research group has turned its attention to the protein snapin. When snapin binds to cypin, tubulin is crowded out, so fewer dendrites assemble and mor...

Endocannabinoids ?the brain's cannabis ?demonstrate novel modes of action to stress

...have on our mood and our social behavior. Cannabis works this way because it acts like substances that are produced inside our brains that are messengers between brain cells. Our work involves trying to understand what these substances, endocannabinoids, are for." She said they are particularly interested...

Tetanus toxin found to have therapeutic properties

... than Prozac and more effective than any drug that works by selectively inhibiting the transportation of serotonin in the nerve endings. Behavioural disorders such as depression, anxiety and anorexia may be treated using the molecule derived from tetanus toxin. The researchers have also been able to show ...

New Scripps Oceanography project to study sediments and ecosystem restoration in Venice lagoon

...cal and toxicological implications of major public works in Venice and elsewhere." The field experiment phase by SIOSED scientists will include sediment dredging and transplantation to build six 35-meter-long and 10-meter-wide subtidal banks inside the lagoon. The banks will allow the researchers to test ...

Fruit fly studies open new window on cancer research

... This research tells us more about the way insulin works and so it is furthering our understanding of processes associated with diabetes as well as cancer. We're fortunate that there are a number of groups with clinical interests in these areas in close proximity to us, which should help us assess the med...

Compound from Chinese medicine shows promise in head and neck cancer

...ensive Cancer Center. The compound, (-)-gossypol, works to regulate a protein called Bcl-xL that's overexpressed in cancer cells and makes these cells survive when they shouldn't. Shaomeng Wang, Ph.D., co-director of the Molecular Therapeutics Program at the U-M Comprehensive Cancer Center, discovered (-)...

New technique rapidly detects illness-causing bacteria

...ng Escherichia coli (E. coli ). The new biosensor works in a test tube and a positive result shows up as a red line on a strip, much like a pregnancy test. Newly designed software gives researchers a powerful tool for increasing the sensitivity of the analysis. The method may help researchers and compani...

What comes first…the chicken, the egg, or the bad attitude?

...later. No other broiler breeders research program works as closely with individual birds. The research team has shown the importance of recognizing that large poultry populations are made up of a collection of individuals--each with their own way of balancing their growth and reproductive priorities. "Bui...
