Dopamine drug leads to new neurons and recovery of function in rat model of Parkinson's

...s research. Dr. Eckman and Dr. Van Kampen are now looking at how different doses of pramipexole and similar drugs affect neurogenesis. Once they identify the most effective doses in animals, researchers might be able to test comparable doses in humans. They are also carrying out experiments to learn if us...

AIDS vaccine research offers new insights on survival

...ndings now provide us with an important new way of looking at subpopulations of CD4 helper T-cells and suggest how they may be used as a marker to gauge the efficacy of these vaccines." The work was spearheaded by Letvin and his colleagues at the VRC, which is dedicated to improving global human health thro...

Biologists find regions of rice domestication

Biofuels researcher searches for new sources

... of the country's fuel needs. So researchers are looking for new sources for ethanol. Since the jury is sti...ing on the issue from two directions. First, he is looking at how to maximize the volume of Montana crops or their residues with less input. At the same time, ...

Loosen up, DNA: Leukemia gene changes genetic packaging

...came very simply and clearly ?in red and white. By looking at the eye color of a variety of mutant flies, the team at the University of Rochester Medical Center made a surprising finding about a known cancer gene that meshes nicely with current trends in cancer drug research. Instead of developing drugs th...

Transgenic goat's milk offers hope for tackling children's intestinal disease

...more than a decade, UC Davis researchers have been looking for ways to enrich the milk of cows and goats with some of the beneficial compounds like lysozyme that are found in human breast milk. About eight years ago, they used gene-transfer technology to develop a line of transgenic dairy goats that carry t...

Brain-computer link lets paralyzed patients convert thoughts into actions

...portable wireless system. The researchers are also looking at new applications, such as enabling the brain-computer combo to control a wheelchair or other gadgets that will restore some control and freedom to patients with severe paralysis. At the American Spinal Cord Injury Association meeting in June, Da...

Stimulation of the semicircular canals can artificially control human walking and balance

...ce or steering, such as the movements we make when looking around, and then transforms the remaining signal into two components. One component is used to control steering, and the other to control balance. In a more practical view, this ability to produce illusions of movement, and then steer and balance the...

Pathway toward gene silencing described in plants

... the importance of RNA Polymerase IVa (Pol IVa) by looking at a Pol IVa mutant and noting that the rest of the proteins didn't localize properly. In the RNA-dependent RNA polymerase 2 (RDR2) mutant, Pol IVa is unaffected, but the function of all the other proteins downstream is lost, inferring that it came...

Tumor wizardry wards off attacks from the immune system

... tumor growth and increased survival time. "We're looking at several potential ways to interfere with tumor recruitment of T-reg cells," Linehan says. "We'd like to see these findings advance cancer immunotherapy. We want to find a way to actively suppress T-reg cells and at the same time actively evoke an ...

UC Davis researchers reveal apples' protective ways

... The UC Davis study takes that research further by looking beyond the antioxidant effects of apple flavonoids. In the current study, Gershwin and his colleagues exposed human endothelial cells to an extract of an apple mash made from different apple varieties. The researchers then challenged these cells by ...

What's nature worth? New computer models tell all

...e impacts of different land use decisions--whether looking at a local watershed or whole continent. Over th...like global climate regulation. "Instead, we're looking for effects of ecosystems on human welfare, whether people perceive them or not--rather than just as...

Combined treatment extends life expectancy for lung cancer patients

... Rhode Island Hospital. In a retrospective study looking at patients over seven years, the median survival rate at three years increased from 20 months after radiation alone to 42 months when thermal ablation was followed by radiation for treatment of non-small-cell lung cancer. The results are published i...

New strategy rapidly identifies cancer targets

...nally, cancer-gene hunters have scanned the genome looking for mutations that trigger out-of-control cell growth. Druker tried this approach, but found it wanting. "We were doing some high-throughput DNA sequencing, and we weren't really finding much," he said. Instead, the team added tools from the burge...

New light microscope sharpens scientists' focus

...oscopy, producing a revolutionary new approach for looking at the cell in molecular detail." For now, Hess and Betzig have focused on creating PALM images with a single fluorescent protein, which limits them to mapping a single target protein per sample. "Right now the resolution is wonderful, but it's al...

Combating anthrax: Results of study published this month as researchers look for a better vaccine

... vaccine produced the immune response doctors were looking for, according to peer-reviewed research published in Vaccine . In its first human testing, the vaccine was given to 100 volunteers at four sites around the United States, said Geoffrey Gorse, M.D., a Saint Louis University researcher who was the m...

Researchers identify human DNA on the fast track

...ces to those of our closest evolutionary relative, looking for the differences that distinguish the two species. Now a team of researchers has found the human DNA sequence with the most dramatically increased rate of change. The function of this region of DNA is still unknown, but it appears to be directly ...

New GI technologies improve internal organ visualization

...tegrated into the medical setting, researchers are looking for new ways to utilize these technologies to increase procedural effectiveness and accuracy. Scientists from Charlottesville Medical Research in Virginia, have continued this trend to monitor and deliver sedation during surgery with computer assist...

Researchers seek to solve mystery of natural HIV control

...y 200 participants from 25 U.S. states, and we are looking forward to adding participants from other countries," says Pereyra. Potential participants or collaborating providers seeking more information should contact Rachel Rosenberg, Partners AIDS Research Center, (617) 726-5536 or rrosenberg2@partners.or...
