Studies to find better ways to preserve human eggs, ovarian tissue under way

...opacity of ice cubes and frozen meats, a tell-tale sign of ice crystals within. Dr. Song, whose research lab is in MCG’s biotech incubator, has developed cryoprotectants that can be used safely in higher doses as well as agents to help protect tissue during the ultra-rapid process of de-vitrification. ...

In mice, drug protects against diabetes and atherosclerosis

... mice lacking these lipid chaperones, there was no sign of heart disease. Next, the researchers turned to humans. While the scientists could not knock out the aP2 gene in humans, they could focus on subjects in the large Nurses' Health Study and the Health Professionals Follow-Up study who were overwei...

Mice with a migraine show signs of brain damage

...says those disturbances might actually be a visual sign that parts of the brain are short of oxygen. In the work described in Nature Neuroscience, Nedergaard studied a phenomenon known as cortical spreading depression, or CSD. The process is now considered by many scientists as the basis for some migra...

Scientists: As rainfall changes, tropical plants may acclimate

...mption," the PNAS paper says. That's a positive sign considering that as the Earth warms, some areas of the tropics are widely expected to be wetter, some drier. So, at least one of dozens of variables that will change with precipitation changes ?nutrient uptake ?might not affect tropical plants. That...

Palau's coral reefs show differential habitat recovery following the 1998 bleaching event

...linked to human environmental factors ?a promising sign for recovery in other regions. "Factors such as river pollution, sedimentation, and use changes ?such as fishing pressures ?are all controllable factors," says van Woesik. "They’re added to global effects of greenhouse gas emissions th...

Researchers from the University of Navarra analyze new kinds of cancer-fighting antibodies

...he tumor), which the researchers see as a positive sign to continue with the research. Currently, the researchers study its benefits in cancer survivors through two clinical tests in the third phase. In two years we will test its use as the sole means of treatment, and we will need more time in order t...

Researchers identify ovarian cancer biomarkers

... when these genes are highly expressed it may be a sign of a tumor that's able to grow blood vessels more efficiently, and therefore is more aggressive. This may help us down the road in treatment decisions," says lead study author Ronald Buckanovich, M.D., Ph.D., assistant professor of internal medicine ...

Cold sore virus might play role in Alzheimer's disease

...se. Cold sores that come and go are the outward sign of the two different phases of the virus's life cycle. Herpes simplex is a chronic infection that lives in a person for a lifetime, periodically flaring up in a "lytic" phase where it causes cell damage, then retreating and seeking safe harbor within...

Antifungal drug kills TB bug

...ies dormant, usually in the lungs, waiting for any sign of weakness, such as a secondary infection. Its resurgence over the last 20 years has been closely associated with the AIDS epidemic, which destroys the human immune system and has allowed TB to get a grip once again." London is the TB capital of ...

Antibody therapy prevents type 1 diabetes in mice

...ymphocytes in their pancreatic islets, a tell-tale sign of pancreatic inflammation and autoimmunity. In addition, when the researchers isolated cells from the spleens of the antibody-treated mice and injected these cells into immune-deficient NOD mice, seven of the nine recipient mice developed type 1 dia...

Mechanisms involved with tumor relapse identified

...amma by lymphocytes against tumors is considered a sign of good prognosis; however, recent study findings indicate that this may not be the case. The findings were reported in the March 2007 issue of the European Journal of Immunology, the official journal of the European Federation of Immunological Socie...

Destructive enzyme shows a benevolent side

.... But the researchers were unable to detect any sign that the message was destroyed. "The fact that we don't see an acceleration of mRNA decay suggests that something in the stress response protects these mRNAs from being degraded, even though the degrading enzyme PMR1 is there in the stress granule...

DNA ends: Common tool, different job

... the cell can no longer multiply ?a characteristic sign of cellular senescence. In certain cells, such as our germ cells or baker's yeast cells, which need to divide indefinitely, an enzyme called telomerase elongates telomeres to compensate for the continual attrition at chromosome ends. At the same ...

Lost dogs found more often than lost cats, study suggests

... of the best ways to locate a pet may be to post a sign in the neighborhood, the study showed. Posted signs resulted in the return of 15 percent of recovered dogs and 11 percent of found cats. Six dogs (4.5 percent) and two cats (3 percent) made it home because of an advertisement in the newspaper. "L...

Twin studies reveal genetic components leading to cardiac and kidney disease

... Excretion of the protein albumin in urine is one sign of kidney disease, which can be a complication of diabetes. "Normally kidneys filter the blood to rid the body of accumulated toxins. In healthy kidneys, more than a million little ‘baskets?or ‘sieves?filter out the bad chemicals without leaking ...

Scientists find new genetic clue to cause of Alzheimer's disease

...ribute to formation of amyloid plaques, a hallmark sign of Alzheimer's in the brains of people with the disease. They identified 29 variants that mark relatively short segments of DNA where disease-causing changes could lie. The study did not, however, identify specific genetic changes that result in Alzh...

Amur leopard still on the brink of extinction, scientists say

...were encountered during the census. This is a good sign because it means that the population is not completely depressed and is still able to restore itself. But for long-term survival, at least 100 animals are needed. "Conservation of large predators needs vast territories with minimal anthropogenic c...

Napoleon's mysterious death unmasked, UT Southwestern researcher says

...st 20 pounds in the last six months of his life, a sign of gastric cancer. The autopsy descriptions show that Napoleon's stomach was filled with a dark material that resembled coffee grounds, an indication of gastrointestinal bleeding that likely was the immediate cause of death, Dr. Genta said. The most ...

Making mice with enhanced color vision

...ition to their own can acquire new color vision, a sign that the brain can adapt far more rapidly to new sensory information than anticipated. This work, appearing March 23 in Science, also suggests that when the first ancestral primate inherited a new type of photoreceptor more than 40 million years ag...

Anti-herpes treatment reduces HIV levels in women infected with both viruses

...ncrease over the 3 month follow-up period, with no sign of abating.' These results indicate a new way to possibly reduce the sexual transmission of HIV from already infected individuals to their partners, since the frequency and quantity of HIV in the female genital tract are closely related to the trans...
