Scientists use gene transfer technology and common virus to block neuropathic pain in animals

...nucleus of nerve cells in the dorsal root ganglion near the spine. In previous studies, the researchers have confirmed that the vector remains in the dorsal root ganglion, but an enzyme expressed by the GAD gene moves to nerve terminals in the spinal cord where it triggers production of a powerful neurotr...

Disappearing arctic lakes linked to climate change

...llite data of tundra ponds on the Seward Peninsula near Council, Alaska and found that the surface pond area there had decreased over the last 50 years. In this latest study, comparing data from 1973 with findings from 1997-98, the total number of large lakes decreased by around 11 percent. While many di...

Exercise aside, genes may ultimately dictate seniors' mobility

...eg muscles," Kritchevsky said. "Now energy storage near muscles may benefit young athletes engaged in endurance activities, but in older persons, accumulation of leg fat has been linked to poorer muscle function and metabolic diseases like diabetes." The study, funded by the National Institute on Aging a...

NASA satellite data provides rapid analysis of Amazon deforestation

...sults of this study, Brazil's INPE has developed a near or almost real time monitoring application for deforestation detection known as the DETER system. While this study highlights the challenges of monitoring deforestation and the use of MODIS data in the Amazon, it also shows that similar MODIS analys...

Ethanol and biodiesel from crops not worth the energy

...ely needs a liquid fuel replacement for oil in the near future," says Pimentel, "but producing ethanol or biodiesel from plant biomass is going down the wrong road, because you use more energy to produce these fuels than you get out from the combustion of these products." Although Pimentel advocates the ...

Tropical Deforestation affects rainfall in the U.S. and around the globe

... of deforestation on precipitation is found in and near the deforested regions, it also has a strong influence on rainfall in the mid and even high latitudes," said Roni Avissar, lead author of the study, published in the April 2005 issue of the Journal of Hydrometeorology. Specifically, deforestation of...

Birds and bats sow tropical seeds

...ues will lease 16 land parcels in Veracruz located near or adjacent to forest remnants or UNAM's protected rainforest to observe what trees grow, and why. Some tracts will be planted with 12 species of animal-dispersed trees, which will ultimately provide living bait with crops of bat- and bird-dispersed ...

Experimental shingles vaccine proves effective in nationwide study

...to clusters of sensory nerve cells usually located near the spinal cord, where the virus persists in a dormant state. As immunity weakens with advancing age, the virus can reactivate, multiply in and damage sensory nerve cells to cause pain. It then migrates to the skin, causing the blistering rash of shi...

Tiny avalanche photodiodes target bioterrorism agents

...ld be capable of efficient detection of light with near single photon precision. Previously, photomultiplier tubes (PMTs) were the only available technology in the short wavelength UV portion of the spectrum capable of this sensitivity. These fragile vacuum tube devices are expensive and bulky, hindering ...

NHGRI expands effort to revolutionize sequencing technologies

...from now, some of these technologies will be at or near commercial availability. Grant recipients and their approximate total funding are: Gina L. Costa, Ph.D., Agencourt Personal Genomics., Beverly, Mass. $1.2 million (2 years) "Bead-Based Polony Sequencing" Supplemental funding is expected to accelera...

Fighting malaria by manipulating mosquitoes' sense of smell

...tests will be field tested in cooperating villages near Ifakara and in The Gambia under the supervision of IHDRC and MRC Laboratories' researchers. "By combining laboratory-based and field-based studies, we expect to establish an effective strategy for developing extremely powerful attractants and repell...

Vaginal gel may provide a new approach to HIV prevention

...block SHIV from fusing with its target cells at or near the tissue lining of the vagina, to see whether this would prevent the virus from entering the monkeys' bodies. The test compounds were provided by Bristol-Myers Squibb Inc., Merck Research Laboratories and Weill Medical College of Cornell Universit...

U-M scientists discover identifying markers for primitive blood-forming stem cells

... of the SLAM family of cell surface receptors, was near the top of the list. To see if CD150 was expressed on hematopoietic stem cells, Kiel and Yilmaz transplanted CD150+ and CD150- cells into laboratory mice whose bone marrow had been destroyed by lethal doses of radiation. Healthy bone marrow was rest...

Hunger in America rises by 43 percent over last five years

Software 'agents' could help unmask reality of disease clusters

...rything from cancer clusters to the risk of living near to hazardous waste sites is often restricted, altered or aggregated in order to protect the identity of individual patients. But researchers say that these measures often make it impossible for them to carry out accurate geographical analyses of pub...

Research casts doubt on circulating stem cells

...n production in the muscle, the effect was nowhere near the level needed to combat the disease. But we shall continue working on this and try to awaken those 'sleeping beauties', the nuclei." The Bonn physiologist believes that it is necessary to dampen the very high expectations held by some colleagues:...

Purdue's gold nanorods brighten future for medical imaging
