Treating bacteria with insufficient levels of antibiotics leads to multidrug resistance in 'superbugs'

For years, doctors have warned patients to finish their antibiotic prescriptions or risk a renewed infection by a "superbug" that can mount a more powerful defense against the same drug. But a new study by Boston University biomedical engineers indicates that treating bacteria with levels of antibiotics insufficient to kill them produces germs that are cross-resistant to a wide range of antibiotics.

Low doses of antibiotics may serve as active mutagens and lead to multidrug resistance

Multidrug resistant bacteria such as Methicillin-resistant Staphylococcus aureus (MRSA) pose a major problem for patients, doctors, and the pharmaceutical industry. To combat such bacteria, it is critical to understand how resistance is developed in the first place. It is commonly thought that an incomplete course of antibiotics would lead to resistance to that particular antibiotic by allowing the bacteria to make adaptive changes under less stringent conditions.

Cancer drug could be effective for treating recurrent nose bleeds

Patients suffering from hereditary hemorrhagic telangiectasia (HHT), an inherited vascular condition characterized by profuse nosebleeds, may find hope in a cancer-fighting drug called bevacizumab, also known as Avastin.

Chemical compound found in blood shows promise in preventing intractable form of heart failure

A chemical compound found normally in the blood has shown promise in treating and preventing an intractable form of heart failure in a mouse model of the disease, report researchers at the University of Illinois at Chicago College of Medicine.

Bombarding DNA nucleotides and mammalian meat with ‘femto-neutrons’ open new path to femtomedicine

Bombarding DNA nucleotides and mammalian meat with ‘femto-neutrons’ has opened up the path to femtomedicine, an entirely new cancer diagnostics, it was reported today at First Global Congress on NanoEngineering for Medicine and Biology in Houston, TX.

Vision of mountain climbers not adversely affected despite presence of edema at altitudes up to 6,300 meters

Swelling commonly occurs in the corneas of mountain climbers, but does not appear to affect vision at altitudes of up to 6,300 meters (about 20,670 feet), according to a report in the February issue of Archives of Ophthalmology, one of the JAMA/Archives journals.

Future studies may provide clarity on the best approach for pre-surgery beta blockers

In a commentary appearing in this week's Journal of the American Medical Association, heart specialists at the University of Michigan Health System make a plea for clarity on the best approach for prescribing beta blockers before surgery.

Study of complement reaction can help eliminate reperfusion injuries

Researchers have teased out the molecular process that can shut down a marauding, often deadly immune response that kills thousands each year who suffer battlefield casualties, heart attacks, strokes, automobile accidents and oxygen deprivation, according to an article published in the January edition of Molecular Immunology.

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.

CRT, AstraZeneca announce alliance to develop new anti-cancer drugs

Cancer Research UK's commercialisation and development arm, Cancer Research Technology (CRT), today announced it has teamed up with biopharmaceutical business, AstraZeneca in a major, multi-project alliance, in which around 30 scientists will be focused on creating a stream of new anti-cancer drugs, it is announced today (Sunday).

Study finds some vegetative patients show awareness, raising ethical questions

"In a study certain to rekindle debate over life-sustaining care for those with grievous brain injuries, researchers report that five patients thought to be in a persistent vegetative state showed brain activity indicating awareness, intent and, in at least one case, a wish to communicate," The Los Angeles Times reports.

Making relationship between evolution and ecology - a model of reciprocity, say experts

In the natural stream communities of Trinidad, guppy populations live close together, but evolve differently. Upstream, fewer predators mean more guppies but less food for each; they grow slowly and larger, reproduce later and less, and die older. Downstream, where predators thrive, guppies eat more, grow rapidly, stay small, reproduce quickly and die younger.

NHLBI awarded four contracts to test new devices to help children with congenital heart defects

The National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health, has awarded four contracts totaling $23.6 million to begin preclinical testing of devices to help children born with congenital heart defects or those who develop heart failure.

St. Jude Medical receives European approval for Fortify ST ICD and Unify CRT-D defibrillators

St. Jude Medical, Inc. today announced European CE Mark approval and first implants of its Fortify™ and Fortify ST implantable cardioverter defibrillators (ICD) and Unify™ cardiac resynchronization therapy defibrillator (CRT-D). The devices will be fully launched in Europe later this spring, and U.S. versions of the Fortify ICD and Unify CRT-D are expected to be launched later this year. The reduced size of these new devices compared to those of previous generations creates the smallest available device footprint in the industry.

Transplantation of pulmonary progenitor cells derived from hESCs promising for acute lung injury

Stem cell researchers exploring a new approach for the care of respiratory diseases report that an experimental treatment involving transplantable lung cells was associated with improved outcomes in tests on mice with acute lung injury. The lung cells were derived from human embryonic stem cells (hESCs). Findings by investigators at The University of Texas Health Science Center at Houston are scheduled to appear in the March issue of Molecular Therapy.

Sudden infant death syndrome linked to low serotonin levels

Taking the next step in more than 20 years of research, researchers at Children's Hospital Boston have linked sudden infant death syndrome (SIDS) with low production of serotonin in the brainstem, based on a comparison of brainstem samples from infants dying of SIDS compared to brainstems of infants dying from other, known causes.
