Functional human blood vessels grown in mice using cells from adult human donors

For the first time, researchers have successfully grown functional human blood vessels in mice using cells from adult human donors - an important step in developing clinical strategies to grow tissue, researchers report in Circulation Research: Journal of the American Heart Association.

Young women's breast cancers more aggressive and less responsive to treatment

Young women's breast cancers tend to be more aggressive and less responsive to treatment than the cancers that arise in older women, and researchers at the Duke Comprehensive Cancer Center and the Duke Institute for Genome Sciences and Policy may have discovered part of the reason why: young women's breast cancers share unique genomic traits that the cancers in older women do not exhibit.

New understanding of how malaria parasite survives in and totally changes red blood cells

A new study-done on a scale an order of magnitude greater than anything previously attempted in the field of malaria-has uncovered an arsenal of proteins produced by the malaria parasite that allows it to hijack and remodel human red blood cells, leaving the oxygen-carrying cells stiff and sticky.

Lowering blood pressure reduces the risk of dementia

New research suggests that lowering blood pressure in older people could reduce their chances of dementia by 13%.

Hydrogen sulfide significantly improves survival after extreme blood loss

For the first time, researchers have demonstrated that the administration of minute amounts of inhaled or intravenous hydrogen sulfide, or H2S - the molecule that gives rotten eggs their sulfurous stench - significantly improves survival from extreme blood loss in rats.

100 percent oxygen resuscitation after brain injury may do more harm than good to children

The current standard practice of giving infants and children 100 percent oxygen to prevent brain damage caused by oxygen deprivation may actually inflict additional harm, researchers at UT Southwestern Medical Center have found.

Wound-cleaning laser kills harmful bacteria

A laser-activated antimicrobial offers hope for new treatments of bacterial infections, even those that are resistant to current drugs. Research published today in the open access journal BMC Microbiology describes the use of a dye, indocyanine green, which produces bacteria-killing chemicals when lit by a specific kind of laser light.

Neuroscientists pinpoint how neural activity boosts blood flow to the brain

New research from Harvard University neuroscientists has pinpointed exactly how neural activity boosts blood flow to the brain. The finding has important implications for our understanding of common brain imaging techniques such as fMRI, which uses blood flow in the brain as a proxy for neural activity.

House votes 355-59 to approve legislation that would delay Medicare physician fee cut

The House on Tuesday voted 355-59 to approve legislation (HR 6331) that would delay for 18 months a 10.6% reduction to Medicare physician fees scheduled to take effect on July 1, among other provisions, the Washington Post reports (Kane, Washington Post, 6/25).

House to vote on modified version of Senate Democrats' Medicare physician pay patch bill

The House on Tuesday is scheduled to vote on a modified version of Senate Finance Committee Chair Max Baucus' (D-Mont.) legislation (S 3101) that would eliminate a 10.6% reduction to Medicare physician fees scheduled for July 1, CQ Today reports. According to CQ Today, "If the House moves a bill, it will put pressure on Senate Democrats and Republicans to reach an accord."

Premature babies feel pain but don't show it

Brain scans of premature babies undergoing a simple medical procedure have revealed though they may appear to be pain free, they are experiencing pain.

New details on how low blood flow promotes vascular disease

Researchers have found the first direct proof that a key protein drives the clogging of arteries in two ways, and that lowering levels of it opens them up, according to study results published in the June edition of the journal Circulation.

Lower blood levels of vitamin D linked to increased heart problems

Individuals with lower blood levels of vitamin D appear to have an increased risk of death overall and from cardiovascular causes, according to a report in the June 23 issue of Archives of Internal Medicine.

Gene radiotherapy system shows promise for fighting treatment-resistant cancer cells

A gene radiotherapy system that detects and treats cancer cells that are resistant to traditional forms of chemotherapy and radiation showed success in the laboratory and could eventually prove beneficial for cancer patients, according to researchers at the Society of Nuclear Medicine's 55th Annual Meeting.

Smoking and obesity linked to hearing loss

One of the largest studies into the risk factors for age-related hearing loss has found that smoking and body mass index (BMI) are two of the main culprits whereas alcohol has a protective effect, but high levels of work noise remain the biggest risk.

Oxygen-rich lifesaving efforts pose risk for respiratory infections

Each year, thousands of premature infants battle to breathe. Thanks to life-saving interventions developed in the past couple decades - steroids given to their mothers to stall pre-term labor, mechanical ventilation, air enriched with extra oxygen, and surfactant, a crucial wetting agent that makes breathing less work - most of these newborns survive with enough lung function to grow and go home.

Memory loss linked to sleep apnea

For the first time, UCLA researchers have discovered that people with sleep apnea show tissue loss in brain regions that help store memory.
