DNA Recombination and Repair—A New Twist to RecA Function

... these functions has remained obscure. Cox et al. addressed this problem in the test tube, by examining RecA filaments grown from mixing RecA protein with DNA. Previous experiments have shown that filament assembly spreads rapidly in the 5'-to-3' direction once the first RecA molecule is loaded onto DNA. At t...

South America's vast pantanal wetland may become next everglades, UNU experts warn

...systems and environmental problems, they are often addressed at the regional level; the Pantanal is a case in point. Regional institutions can take global environmental issues and refocus them into priorities and a manageable agenda for national governments? "So far, however, most work on Inter-linkages has b...

FDA Approves New Drug to Treat Type I and Type II Diabetes

...e, which can alter the activity of the insulin, is addressed in the Medication Guide and in physician labeling. Finally, the potential for off-label use in patients where the benefit/risk profile has not been characterized or demonstrated is also a concern and will be monitored by the sponsor. The Medication ...

Researchers develop rapid diagnostic tool for pathogen identification

... multiple infectious agents. The new technology is addressed in a paper published in the February issue of the Centers for Disease Control and Prevention's (CDC) Emerging Infectious Diseases. This new platform is demonstrated in an assay that detects and discriminates 22 pathogens including viruses and bacteri...

Use of Insecticides Linked to Lasting Neurological Problems for Farmers

...er neurological symptoms. Some of the insecticides addressed by the study are still on the market, but some, including DDT, have been banned or restricted. These findings will be available online in April, and published in the June issue of Environmental Health Perspectives. The research is part of the ongoin...

The topic is also addressed in an article recently accepted for Applied and Environmental Microbiology, "Toward a System of Microbial Forensics: from Sample Collection to Interpretation of Evidence," by Bruce Budowle of the FBI, Steven E. Schutzer, University of Medicine and De...

New Estimates For The Causes Of Child Deaths Worldwide

...thors state that the causes of child deaths can be addressed through existing, available, and affordable interventions. Reducing deaths in the neonatal period will confront health systems with new challenges, especially in low-income countries they add. (See The Lancet Neonatal Survival Series, March 2005) Pr...

Emergence of cancer as major cause of childhood death in developing countries is not being adequately addressed

...oping regions of the world is not being adequately addressed by national or international health organizations and charities, according to investigators at St. Jude Children’s Research Hospital. This growing rate of pediatric cancer is occurring as the number of children dying from infectious diseases is being...

Science study holds implications for gene therapy and stem cell biology

...nes is activated in a stem cell? This question is addressed in the newly published Science study. Researchers found that they could use the random genome insertion of disabled retroviruses as a tool to discover genes that enhance the fitness of stem cells. Such genes are of great interest for regenerative med...

'Smart drug' targets deadly brain cancer

...O) Annual Meeting in Orlando, Fla. The NCCTG study addressed the most common kind of tumor arising from brain tissue of adults, glioblastoma mutiforme. Current treatment outcomes for this type of cancer are extremely poor: median patient survival is 12 to 16 months, and recurrent disease has a dismal prognosis...

Insects, viruses could hold key for better human teamwork in disasters

...Illinois. "The manner in which extreme events are addressed will influence the future of our cities, as well as redefine the role of the civil engineer," Pena-Mora said. In the epidemiology area of their work, the researchers are looking at the spread of infectious diseases in human populations. In the entom...

U. Iowa researchers improve Huntington's disease symptoms in mice

.... So, an important question that still needs to be addressed is whether adult neurons can tolerate and benefit from a partial reduction of both the toxic and the normal protein. If the normal protein is critical, then RNAi will need to be specifically targeted against the disease-causing gene. Fortunately, RN...

Major new UNC-based drinking water study suggests pregnancy fears may be overstated

FSU scientist warns North Atlantic right whale facing extinction

...h the risk of fishing gear entanglements have been addressed through gear modifications and selective area closures, paper co-authors declare those closures inadequate because they don't fully address the seasonal movement of right whales. The scientists recommend the immediate implementation of interim emerg...

Scientists to mimic nature for newest cancer drugs

David Lipman, Director of the National Center for Biotechnology Information, adds: "Today's nucleotide sequence databases allow researchers to share completed genomes, the genetic make-up of ...

Living with salt

...rs, a number of Weizmann Institute scientists have addressed the question of how molecules essential to life, such as proteins, have adapted to function in extreme environments. The proteins they investigated were isolated from halophilic (salt-loving) microorganisms from the Dead Sea. After determining the 3-...

Aquatic plants may hold key to advancing plant disease management

...ases in freshwater and marine environments will be addressed during the Aquatic Plant Pathology symposium at the APS Annual Meeting in Austin, TX, July 30 - August 3, 2005. The symposium will be held Sunday, July 31 from 1-5 p.m. at the Austin Convention Center. ...

Picky female frogs drive evolution of new species in less than 8,000 years

...aid. "We do have very compelling evidence. We have addressed various lines of evidence and conclude that there has been reinforcement and that has given rise to a new species based on very strong female choice." As a comparison, they looked at a second contact zone on the border between north and south, where...
