Discovery of five genetic variants related to blood pressure in African-Americans

A team led by researchers from the National Institutes of Health (NIH) has reported the discovery of five genetic variants related to blood pressure in African-Americans, findings that may provide new clues to treating and preventing hypertension. The effort marks the first time that a relatively new research approach, called a genome-wide association study, has focused on blood pressure and hypertension in an African-American population.

New breast pumping technique helps preemies’ moms to improve milk supply

Mothers of premature infants shouldn't rely solely on breast pumps to establish and maintain their breast milk supply, researchers at Lucile Packard Children's hospital and the Stanford University School of Medicine have found. Moms already have a simple, safe and free tool for assisting breast milk production: their own hands.

Research reveals major genetic differences between blood and tissue cells

Research by a group of Montreal scientists calls into question one of the most basic assumptions of human genetics: that when it comes to DNA, every cell in the body is essentially identical to every other cell. Their results appear in the July issue of the journal Human Mutation.

Flu mortality formula is potentially misleading, say scientists

A standard calculation used in forecasting potential numbers of deaths during the swine flu pandemic risks misleading healthcare planners by being open to both over- and under-estimation of the true figures, say the authors of new research published today in the British Medical Journal.

Ethicists urge inclusion of pregnant women in Federal child-health study

A team of ethicists from Johns Hopkins, Duke and Georgetown universities is urging organizers of a recently begun $3 billion decades-long study of children's health to immediately add provisions to look at the health and medical profiles of the children's mothers during their pregnancies.

Research may hold key to maintaining embryonic stem cells in lab

In a new study that could transform embryonic stem cell (ES cell) research, scientists at UT Southwestern Medical Center have discovered why mouse ES cells can be easily grown in a laboratory while other mammalian ES cells are difficult, if not impossible, to maintain.

Health indicators in South Africa vary by district, report indicates

In South Africa - "the quality of health care, including access to HIV prevention and testing services," largely depends on which of the country's 52 districts a resident lives in - according to findings in the latest District Health Barometer (DHB), an annual report by Health Systems Trust, IRIN reports. "Some of the inequities highlighted by the [report] can be traced to differences in health spending," IRIN writes.

Specialized glycans act as tumor suppressors

Scientists at Burnham Institute for Medical Research (Burnham) have discovered that specialized complex sugar molecules (glycans) that anchor cells into place act as tumor suppressors in breast and prostate cancers.

Vegetarian diet leads to lower bone density

Even though there has been for some time concern on the part of experts that a vegetarian diet may have negative impact on bone health, until now that opinion has largely been based on anecdotal evidence and a range of contradictory findings which have often relied on studies which experts say are too small to be biologically relevant.

Question marks on credibility of some published clinical trials

Randomised Controlled Trials (RCTs) are considered the 'gold standard' research method for assessing new medical treatments. But research published in BioMed Central's open access journal Trials shows that the design of a remarkable 93 percent of 2235 so-called RCTs published in some Chinese medical journals during 1994 to 2005 was flawed, casting doubt on the reliability of research that is likely to influence medical decision-makers.

Bioethicists lead call for public debates on future uses of stem cells

More than 40 scientists, bioethicists, lawyers and science journal editors are calling on their colleagues, policy makers and the public to begin developing guidelines for the research and reproductive use of stem cell-derived eggs and sperm, even though such use may be a decade or more away.
