Agent slows aging in mice

...ally have been too small and their results hard to confirm in subsequent studies. “The National Institute on Aging decided to fund grants at three institutions to do studies of this sort in the right way,” he says. In six to 10 months, once all the mice in the control group have died, the scientists will...

Blood test may help signal tumor's remission, return in throat cancer patients

...studies are needed in larger groups of patients to confirm if this could be a useful tool to monitor for cancer, infection, or other complications. In addition, because IL-6, IL-8, VEGF, and HGF have been detected in the blood of patients with breast, cervical, ovarian, and other cancers, they suggest that t...

Research team identifies new Alzheimer's gene

...000 SNPs or genetic variations to characterize and confirm additional LOAD susceptibility genes. The search revealed GAB2. Based on the genetics of this and other neuroscientific findings, researchers suggest the healthy form of the GAB2 gene may protect brain cells from developing tangles, one of the hal...

Undergraduate research shows leaderless honeybee organizing

...details of bee social behavior that fundamentally confirm the hypothesis that major colony activities are initiated by the cumulative group actions of the colony’s older workers, not by the queen’s individual decision. What Pierce and colleagues found was that older workers gave signals to the queen and ...

Newly discovered antibody may be body's natural defense against Alzheimer's

...on of disease-modifying treatments. To further confirm that these natural antibodies bind with oligomers,...ers, the researchers explain. "We were able to confirm that the antibodies we found not only recognize oligomers of beta amyloid but also unhealthy forms o...

Massive herds of animals found to still exist in Southern Sudan

...y the New York-based Wildlife Conservation Society confirm the existence of more than 1.2 million white-eared kob, tiang antelope and Mongalla gazelle in Southern Sudan, where wildlife was thought to have vanished as a result of decades-long conflict. Despite the war, some species of wildlife in Southern Sud...

Exploring the dark matter of the genome

...rosophila melanogaster, the fruit fly. The results confirm that heterochromatin is far from mere junk. "Most researchers thought heterochromatin had little or no function, because it appeared to lack the protein-coding genes that occur so richly in the chromosomes' more accessible and better-studied euch...

Clot-dissolving agent may be beneficial in treatment of severe frostbite

...morrhage.” “Additional studies are warranted to confirm our findings and to determine the best methods of assessing tissue damage and administering thrombolytics [anti-clotting drugs] in terms of timing, duration and route,” they conclude....

Students invent protective pouch to enhance cell therapy

...nt a vein, the students used ultrasound imaging to confirm that fluid can flow smoothly through the mesh and can spread the microcapsules throughout pouch. They also demonstrated that the device causes no pressure drop in the model blood vessels and that the microcapsules can easily be injected and withdrawn...

WHO data confirms low level of resistance to Tamiflu

...another antiviral, amantadine2. "These results confirm that the potential for the development of resistance to Tamiflu is very low, even when used extensively in the management of seasonal influenza," commented Dr. David Reddy, Pandemic Task Force Leader, Roche. "This provides reassurance to the scienti...

Better health twice as likely for nonsmokers who live and work with smoking restrictions

...moking bans," notes Dr. Shelley. The data also confirm that among Asian Americans the most at risk are the least acculturated non-English speaking immigrants. Before the New York City Clean Indoor Air Act of 2003, second-hand smoke exposure among this immigrant Chinese population at home and work was h...

Gut research yields new anti-cancer approach

...ew therapeutic effect, and launched experiments to confirm it. Study Details In the newly published study, researchers observed the effects of three compounds known from the literature to inhibit PPARgamma, T0070907, GW9662 and BADGE, on the ability of colorectal tumor cells to survive. High doses (...

Study shows isolation of stem cells may lead to a treatment for hearing loss

...ange of developmental markers unique to hair cells confirm the possibility that self-supporting hair cell precursors exist in or can be derived from the postnatal mammalian cochlea. Currently there are no clinical treatments to repair these hair cells vital to normal hearing. In the United States, 30% ...

Loss of a universal tRNA feature reported

...cation and tRNA sequencing approaches were used to confirm the findings. Sinorhizobium meliloti and Caulobacter crescentus are members of the alphaproteobacteria, a group of diverse organisms whose members have successfully adopted different lifestyle and energy-yielding strategies in the course of evolut...

3-D ultrasound identifies women at risk for impending preterm birth

...eates the basis for further prospective studies to confirm that 3-dimensional ultrasound assessment of the fetal adrenal gland volume can assist clinicians with devising better therapeutic and preventive interventions for preterm birth....

Scientists find new genes for Crohn's disease

... sets of patients and healthy controls in order to confirm their significance. After all of the comparisons, the consortium identified variations in three genes ?PHOX2B, NCF4 and ATG16L1 ?as contributing significantly to the risk for Crohn's disease. According to corresponding author John D. Rioux, Ph.D...

Scientists find method to pick noncompetitive animals, improve production

...found that by using the new tool they were able to confirm two-thirds more inherited trait variations that impact social interactions than could be identified with classical selection analysis. "Now we have a tool to explain how species in nature evolved in response to each other," Muir said. "It can be a...

Smoking ban dramatically reduces air pollution in Irish pubs

...y particulate matter in bar air. "These results confirm that the approach of a total ban on smoking in the workplace is successful in reducing the exposure of workers to particles," said Dr. Clancy. "We have previously shown that a reduction of particle levels in ambient air resulted in marked health bene...

Scientists discover new life forms in the Arctic Ocean

...ying new techniques to their samples. They can now confirm that these new life forms are abundantly distributed throughout northern seas. They have yet to be brought into culture, but can be seen using advanced microscopy techniques. "It's a very exciting discovery," comments Dr. Lovejoy. "The ocean cover...
