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.

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.

Pioneering paper claims Earth's chemical energy powered early life

For 80 years it has been accepted that early life began in a 'primordial soup' of organic molecules before evolving out of the oceans millions of years later. Today the 'soup' theory has been over turned in a pioneering paper in BioEssays which claims it was the Earth's chemical energy, from hydrothermal vents on the ocean floor, which kick-started early life.

New weight-loss supplement burns calories

A new weight-loss supplement tested by the University of Oklahoma Health and Exercise Science Department has the potential to burn as many calories as a 20-minute walk, according to Joel T. Cramer, assistant professor of exercise physiology.

Decreased levels in brainstem of serotonin associated with increased risk for SIDS

Preliminary research indicates that decreased levels in the brainstem of serotonin (5-hydroxytryptamine [5-HT]; a neurotransmitter involved in several brain functions) and tryptophan hydroxylase (TPH2; an enzyme involved in the synthesis of serotonin) are associated with an increased risk for sudden infant death syndrome (SIDS), according to a study in the February 3 issue of JAMA.

Play soccer to eliminate lifestyle-related diseases

Other parallel experiments on both women and men further demonstrates that a regular game of soccer affects numerous cardiovascular risk factors such as maximal oxygen uptake, heart function, elasticity of the vascular system, blood pressure, cholesterol and fat mass far more than e.g. strength training and just as much if not more than running.

CTS: More people are being admitted to Canadian hospitals each year with COPD

A review of Canadian data by the nation's leading lung specialists has provided the factual evidence to support what respirologists across the country have been suspecting for some time. Shockingly, more people are being admitted to Canadian hospitals each year with chronic obstructive pulmonary disease (COPD) than any other major chronic illness (including heart attacks) and that number has been increasing dramatically in recent years.

FDA approves neurostimulation treatment for heart failure

The FDA recently approved the first study of neurostimulation as a treatment for heart failure, a chronic disease that affects nearly six million Americans and is the leading cause of hospitalization in America.

Study assesses gray matter concentration deficits in multiple brain areas of people with OSA

A study in the Feb. 1 issue of the journal SLEEP found gray matter concentration deficits in multiple brain areas of people with severe obstructive sleep apnea (OSA). The study suggests that the memory impairment, cardiovascular disturbances, executive dysfunctions, and dysregulation of autonomic and respiratory control frequently observed in OSA patients may be related to morphological changes in brain structure.
