Medical experts: US unlikely to have enough vaccines to stop avian flu

...ing the spread of infectious diseases has not been extensively studied, Bruine de Bruin said. Although the federal government has expressed a commitment to open communication about these risks, its messages have not yet been scientifically evaluated, according to Fischhoff. ...

Stem cells from muscles can repair cartilage

...ough stem cells derived from bone marrow have been extensively investigated for the repair of cartilage defects, the current study is the first to investigate using enriched stem cells from muscle. The author states that the results are encouraging, especially the successful use of fibrin glue to fill in the def...

Dog genome sequenced

...ts that are common in mammals and have contributed extensively to genome evolution. In their publication, Drs. Wei Wang and Ewen Kirkness, scientists at The Institute for Genomic Research, report the identification of more than 10,000 SINE insertions in the canine genome and describe the potential impact of the...

Scientists fetch useful information from dog genome publications

OHSU discovery sheds light into how stem cells become brain cells

...d humans. This protein had been previously studied extensively in human cancers, but not in the nervous system. To determine the precise role of Brg-1, Sherman, in collaboration with Dr. Steven Matsumoto from the Integrative Biosciences Department at the OHSU School of Dentistry, bred mice lacking the gene in th...

Research: Snails were overlooked contributors to marsh destruction

...es such as cordgrass, or Spartina alterniflora, so extensively that the snails moved from finishing off stressed patches to decimating large pockets of otherwise healthy marsh in concentrated waves. The result: the loss of an estimated 250,000 acres of marsh stretching over 900 miles on the Gulf and southeastern...

New insights into the software of life

...ained. The second of the papers in Science deals extensively with another area to which the IMB team has made a major contribution; outputs of the genome (RNAs) that do not code for protein. IMB Director Professor John Mattick, co-author of these papers, has predicted the importance of non-coding RNA in deve...

Mammalian Transcriptome Mapped

...nciple may be used by nature on a massive scale to extensively modulate the gene expression within in our cells. It's still unclear whether the majority of antisense sequences are involved in regulation or in some other biology, he adds, but this result is likely to fuel research for years to come. The article...

Zebrafish may hold key to improved cancer research

...to new cancer therapies." Using zebrafish, OSU has extensively studied two groups of carcinogens, polyaromatic hydrocarbons, or PAHs, and nitrosamines. Both of these groups can be produced by normal living activities, ranging from preserved foods to smoking and use of wood stoves. University researchers have als...

Chernobyl: The true scale of the accident

...ected by Chernobyl have been studied and monitored extensively for the past two decades. Major releases of radionuclides continued for ten days and contaminated more than 200,000 square kilometers of Europe. The extent of deposition varied depending on whether it was raining when contaminated air masses passed. ...

Research suggests fitness of Florida panthers improved by limited breeding with Texas animals

...the Doris Duke Charitable Foundation. The authors extensively reviewed the locations and movements of both purebred and hybrid panthers that researchers had tracked by radio. In 1995, separate pairs of Texas female panthers fitted with radio collars were released in each of the four sections of South Florida ...

Primate virus jumps species barrier to humans for first time in Asia

...imate-to-human viral transmission has been studied extensively in Africa, largely because that is where HIV originated," explains Dr. Lisa Jones-Engel, lead author of the study and a research scientist in the Division of International Programs at the Washington National Primate Research Center. "But there has no...

Fundamental discovery -- Bone fracture

...ng that." Hansma noted that bone has been studied extensively since Galileo. "Galileo wrote a really nice paper ... published every six minutes. And although bone is extensively studied, little is known about how it works at the molecular level. "Our paper is the beginning rese...

Stem Cells Found In Cerebellum; Possible Cell of Origin for Childhood Brain Tumors

... are known for their unique ability to proliferate extensively and give rise to both new stem cells as well as a host of specialized cells that perform designated tasks in a particular tissue or organ. But when stem cells become activated at the wrong time or place, rapid proliferation can give rise to cancer, s...

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

...talian partners. Although Venice has been studied extensively by scientists, SIOSED researchers will provide decision makers with further information for assessing geochemical and microbial processes involved in sediment movement--whether natural or manmade--and their effects in such a sensitive ecosystem. "SI...

Snapin: A protein with therapy potential for autism

...te the patterning activity." Firestein has worked extensively with cypin, a protein that regulates dendrite numbers (a news release is posted online at ur.rutgers.edu/medrel/viewArticle.html?ArticleID=3708 ). Cypin works on tubulin, a protein that is a structural building block of the dendrite skeleton. Now Fi...

Bacteria feed on smelly breath (and feet)

...function of bacterial flora of the mouth have been extensively studied in the past, but until now it was not recognised that methylotrophic bacteria are part of the normal oral microbial environment or 'microflora'. The researchers found no difference between strains of bacteria found in the mouths of healthy v...

UN: World in big ecological mess

.... Humans have changed ecosystems more rapidly and extensively in the last 50 years than in any other period, some 60 per cent of ecosystem elements supporting life on Earth, such as fresh water, clean air or a relatively stable climate, are being degraded or used unsustainably, and the situation could become si...

Searching the depths of the straits of Florida for disease cures

...h has used its submersibles to explore the Bahamas extensively since the 1970s, this will be the institution's first trip to Cay Sal. Almost no information is available about the area's deepwater habitats. Ultimately, Harbor Branch's drug discovery group hopes to add to its growing collection of compounds derive...

Researchers test new therapy for advanced melanoma

...mal model to the patient. Dr. Heller's team worked extensively with Dr. Daud to adapt the electroporation technique used on mice to humans. The researchers injected the DNA plasmid, which encodes a gene that stimulates the immune system, directly into the tumor site in mice. Then, they applied electroporation t...
