More interventions at delivery not linked to healthier newborns

In low-risk pregnant women, high induction and first-cesarean delivery rates do not lead to improved outcomes for newborns, according to new research published in the April issue of The Journal of Maternal-Fetal and Neonatal Medicine.

The finding that rates of intervention at delivery – whether high, low, or in the middle – had no bearing on the health of new babies brings into question the skyrocketing number of both inductions and cesarean deliveries in the United States.

New fracture resistance mechanisms provided by graphene

TUCSON, Ariz. and TROY, N.Y. (April 13, 2011) -- A team of researchers from the University of Arizona and Rensselaer Polytechnic Institute have increased the toughness of ceramic composites by using graphene reinforcements that enable new fracture resistance mechanisms in the ceramic.

Experts at Experimental Biology examine dietary cholesterol, egg intake and heart disease risk

Park Ridge, IL (April 13, 2011) – This week at Experimental Biology (EB) 2011 in Washington, D.C., long-standing beliefs about dietary cholesterol intake and cardiovascular disease risk were examined as part of a scientific symposium and a variety of poster presentations. Experts from leading institutions discussed existing and emerging science regarding dietary cholesterol intake and its association with heart disease risk, dispelling some commonly heard myths.

Low doses of penta-brominated diphenyl ether flame retardants alter gene expression

Polybrominated diphenyl ethers (PBDEs) are chemicals that have been widely used as flame retardants and are now classified as persistent organic pollutants. Health concerns in humans have arisen based primarily on studies with laboratory animals exposed to high levels of PBDEs. Three commercial mixtures of PBDEs have been manufactured in or imported into the United States which include penta-, octa-, and deca-brominated diphenyl ethers (BDEs). Of particular concern has been the penta-BDEs used primarily in foams in computers, televisions, mattresses, pillows, carpets, and furniture.

Coffee in capsules contains more furan than the rest

"Preparing a coffee in a drip coffee maker is not the same as making one in an espresso machine or from capsules, because these give rise to differing levels of furan", Javier Santos, a professor at the Department of Analytical Chemistry at the University of Barcelona and lead author of the study, tells SINC.

Concern has risen over recent years about the presence of this compound in foods, because of its toxic and carcinogenic effects in animals, as well as the fact that the International Agency for Research on Cancer has listed it as a possible carcinogen in humans.

Tiger-parrots show their true evolutionary stripes

Recently released genetic research from CSIRO and New Mexico State University in the US is helping scientists better understand how Australian birds evolved.

The researchers found that the tiger-parrots of New Guinea's rainforests – named for their striped or barred plumage - are not, as has been widely accepted, closely related either to a group of rosella-like parrots found in Australia and Oceania, nor a similar group found in Asia and Africa.

Possible new approach to treating deadly leukemia in babies

MAYWOOD, Ill. -- A Loyola University Health System study points to a promising new approach to treating an aggressive and usually fatal leukemia in babies.

The study involved a type of leukemia called mixed lineage leukemia, or MLL. Only 25 to 50 percent of babies diagnosed with MLL leukemia survive the disease.

The study demonstrated how it may be possible to kill cancerous MLL cells by targeting a protein called DOT1. Researchers showed that, without the DOT1 protein, cancerous MLL cells died, said Charles Hemenway, MD, PhD, senior author of the study.

Small molecules inhibit growth of human tumor cells

Researchers from the Cancer Institute at NYU Langone Medical Center have identified three novel small molecules that interrupt a crucial cellular communication pathway that regulates many aspects of development and cancer. The finding, published in the April 12, 2011 issue of the Proceedings of the National Academy of Sciences and featured on its cover, could provide the basis for innovative therapies for colorectal cancer and other diseases associated with aberrations in this pathway.

Scientists discover a new species of dinosaur, bridging a gap in the dinosaur family tree

A team of scientists led by the Smithsonian Institution has discovered a fossilized dinosaur skull and neck vertebrae that not only reveal a new species, but also an evolutionary link between two groups of dinosaurs. The new species, Daemonosaurus chauliodus, was discovered at Ghost Ranch, N.M. The team's findings are published in the Proceedings of the Royal Society B, Wednesday, April 13.

Eco-friendly treatment for blue jeans offers alternative to controversial 'sandblasting'

Blue denim jeans are one of the most popular and iconic fashion items in the world; now a study published in Biotechnology Journal reveals a cheaper, more efficient and eco-friendly method for treating dyed denim. The process of 'surface activation' used to wash-down the denim following dyeing could also offer an alternative to the dangerous, and internationally banned, sandblasting technique.

Pig stem cell transplants: The key to future research into retina treatment

A team of American and Chinese scientists studying the role of stem cells in repairing damaged retina tissue have found that pigs represent an effective proxy species to research treatments for humans. The study, published in STEM CELLS, demonstrates how stem cells can be isolated and transplanted between pigs, overcoming a key barrier to the research.

Study reveals increased inequality in stroke deaths across Europe and central Asia

There is growing inequality between different countries in Europe and central Asia in the proportion of people who die from stroke, according to a study published online today in the European Heart Journal [1].

Urgent need to improve quality of outpatient care in public and private sector in poorer countries

The overall poor quality of outpatient healthcare in both the formal private and public sector in low and middle income countries is worrying—especially given the increasing volume of chronic conditions, such as diabetes and heart disease, which require relatively sophisticated, long-term outpatient medical care.

Corporate links of global health foundations may conflict with philanthropic interest

Major philanthropic foundations in global health, which often influence and shape the international global health agenda, have links with food and pharmaceutical corporations that could constitute a conflict of interest to the foundations' philanthropic work, reveals a new analysis published in this week's PLoS Medicine.

Comprehensive UGA study reveals patterns in firefighter fatalities

While the number of fires is on the decline, firefighter deaths are not —and a new University of Georgia study helps explain why.

Researchers in the UGA College of Public Health found that cultural factors in the work environment that promote getting the job done as quickly as possible with whatever resources available lead to an increase in line-of-duty firefighter fatalities.
