Mutations that enable Pseudomonas to thrive in cystic fibrosis lung secretions may also guard them against antibiotics

People with cystic fibrosis, an inherited disease that clogs airways with thick mucous, frequently have lung infections that defy treatment. While the life expectancy for children with cystic fibrosis has increased over the past few decades, many lives are still shortened in young adulthood by the ravages of lung infections.

Study: New mechanism may allow bacteria to develop resistance to antibiotics

Scientists have shown that cells' DNA-reading machinery can skim through certain kinds of damaged DNA without skipping any letters in the genetic "text." The studies, performed in bacteria, suggest a new mechanism that can allow bacteria to develop resistance to antibiotics.

Thymosin β4 exhibits potential as new therapeutic agent for liver failure due to chronic HBV infection

REGENERX BIOPHARMACEUTICALS, INC. announced today that researchers have correlated Tβ4 levels with the clinical course of patients with hepatitis B virus-related liver failure. It was reported that serum thymosin β4 levels were significantly lower in patients with chronic hepatitis B infection and that the magnitude of the reduction of thymosin β4 was closely related to the severity of the hepatic injury and to patient death. Since patients with higher Tβ4 levels survived the disease, changes in Tβ4 values could reflect outcome in some liver failure patients.

Dana-Farber Cancer Institute and Sanford-Burnham Medical Research Institute sign license agreement with Genentech

Dana-Farber Cancer Institute and the Sanford-Burnham Medical Research Institute have signed a license agreement with Genentech, a wholly owned member of the Roche group, and Roche, that grants the companies exclusive rights to manufacture, develop and market human monoclonal antibodies to treat and protect against group 1 influenza viruses. These viruses include the strains for the current seasonal and H1N1 influenzas. Genentech and Roche also have a non-exclusive right to manufacture, develop and market diagnostic tests for group 1 influenza.

Beer may help prevent osteoporosis

A new study suggests that beer is a significant source of dietary silicon, a key ingredient for increasing bone mineral density. Researchers from the Department of Food Science & Technology at the University of California, Davis studied commercial beer production to determine the relationship between beer production methods and the resulting silicon content, concluding that beer is a rich source of dietary silicon. Details of this study are available in the February issue of the Journal of the Science of Food and Agriculture, published by Wiley-Blackwell on behalf of the Society of Chemical Industry.

Tβ4 may help treat skeletal muscle disease in Duchenne muscular dystrophy

REGENERX BIOPHARMACEUTICALS, INC. announced today that a research team in Washington, D.C. has found that dystrophin-deficient Mdx mice, treated twice a week for six months with Tβ4, showed a significant increase in skeletal muscle regenerating fibers compared to untreated mice. No effects related to muscle function or fibrosis and no adverse reactions were observed in the mice.

Amantadine binds to and blocks critical M2 proton channel necessary for influenza virus to infect healthy cells

Antiviral drugs block influenza A viruses from reproducing and spreading by attaching to a site within a proton channel necessary for the virus to infect healthy cells, according to a research project led by Iowa State University's Mei Hong and published in the Feb. 4 issue of the journal Nature.

Researchers uncover new mechanism to protect individuals from serious complications of obesity

Although obesity is a risk factor for diabetes and coronary heart disease worldwide, only some obese individuals go on to develop these metabolic complications, while others are relatively protected. Defining these protective factors could help scientists prevent disease in the wider population.

Photocontrolled molecular switch regulates paralysis in animals

In an advance with overtones of Star Trek phasers and other sci-fi ray guns, scientists in Canada are reporting development of an internal on-off "switch" that paralyzes animals when exposed to a beam of ultraviolet light. The animals stay paralyzed even when the light is turned off. When exposed to ordinary light, the animals become unparalyzed and wake up.

New bioanalytical methods have potential for investigative and screening applications

The Springer journal Analytical and Bioanalytical Chemistry (ABC) has chosen Jean-Philippe Frimat (29) as the recipient of its Best Paper Award 2009. Frimat is the lead author of a paper in ABC on plasma stencilling methods for cell patterning.

Research shows DNA looping can impact gene expression

University of Michigan researchers have shown that tension on DNA molecules can affect gene expression---the process at the heart of biological function that tells a cell what to do.

Safer bone marrow transplants

If a team of American scientists are right, bone marrow transplants may become safer and more available to people in need of donations. In a new research paper appearing in the February 2010 print edition of the Journal of Leukocyte Biology (http://www.jleukbio.org), they explain how an anti-inflammatory agent called "ATL146e" may significantly improve the likelihood of success for bone marrow transplants by preventing or halting the progression of graft-versus-host disease, a complication of bone marrow transplants in which the donor marrow attacks the host. Although very rare, graft-versus-host disease can also occur after blood transfusions.

Mouse model demonstrates cell-to-cell connections between implanted stem cells and diseased cells

Investigators at Sanford-Burnham Medical Research Institute (Sanford-Burnham, formerly Burnham Institute for Medical Research), the Karolinska Institutet, Beth Israel Deaconess Medical Center (BIDMC), Harvard Medical School and Universit- Libre de Bruxelles have demonstrated in mouse models that transplanted stems cells, when in direct contact with diseased neurons, send signals through specialized channels that rescue the neurons from death.

Noninvasive optical imaging probes to determine amount and type of cell death in tumors

For quite some time, the "Holy Grail" in medical imaging has been the development of an effective method to image cell death as a means to intervene early in diseases and rapidly determine the effectiveness of treatments. A new paper by researchers at the University of Notre Dame and the Washington University School of Medicine describes important progress in using a synthetic probe to target dead and dying cells in mammary and prostate tumors in living animals.

Blood flowing with force protects against dangerous clogs in blood vessels

It is second nature for most of us that exercise protects against heart attack and stroke, but researchers have spent 30 years unraveling the biochemistry behind the idea. One answer first offered by researchers at the University of Rochester Medical Center is that athletic hearts push blood through arteries with greater force, which alone triggers reactions that protect against dangerous clogs in blood vessels.

Econiche vaccine cited in February, 2010 issue of Scientific American

Bioniche Life Sciences Inc., a research-based, technology-driven Canadian biopharmaceutical company, today announced that Econiche(TM), the world's first vaccine developed to reduce the shedding by cattle of Escherichia coli (E. coli) O157, has been cited in the February, 2010 issue of Scientific American (Vol. 302, # 2).
