Norway study raises new U.S. mammogram overdiagnosis questions

An analysis showing significant mammogram overdiagnosis in Norway has raised new questions about mammograms in the U.S., where some say the overdiagnosis problem could be more rampant because of how early most women begin getting them.

FAAN plays a crucial role in supporting peanut allergy study

Why do some children develop a peanut allergy and others don't? Researchers trying to answer this crucial question in order to learn how to prevent this life-threatening food allergy believe that being exposed to peanuts through skin early in life could be a determining factor.

Stress-induced tolerance can prevent glaucoma

Working in mice, scientists at Washington University School of Medicine in St. Louis have devised a treatment that prevents the optic nerve injury that occurs in glaucoma, a neurodegenerative disease that is a leading cause of blindness.

Preterm or post-term babies with autism more likely to self-injure

For children with autism, being born several weeks early or several weeks late tends to increase the severity of their symptoms, according to new research out of Michigan State University.

Report addresses link between energy density and body weight

A new report published online today in the Journal of the Academy of Nutrition and Dietetics systematically reviews and updates the evidence underlying the recommendation in the Dietary Guidelines for Americans 2010 to consume a diet low in energy density.

Cell graphs link structure of human tissue to corresponding biological function

Computer scientists and biologists in the Data Science Research Center at Rensselaer Polytechnic Institute have developed a rare collaboration between the two very different fields to pick apart a fundamental roadblock to progress in modern medicine. Their unique partnership has uncovered a new computational model called "cell graphs" that links the structure of human tissue to its corresponding biological function.

Fizzy drinks may raise risk of heart disease later in life

About 2,000 12-year-olds took part in the investigation by the University's Westmead Millennium Institute for Medical Research. The scientists found that the children who drank one or more soft drinks each day had narrower arteries in the back of their eyes - a factor associated with increased risk of heart disease and high blood pressure. It is the first study to show that soft drinks and carbohydrates in childhood are linked to narrower retinal vessels.

Study identifies specific chemical in smokeless tobacco products that induces oral cancer

The chemical (S)-N'-nitrosonornicotine, or (S)-NNN, which is present in smokeless tobacco products, is a strong oral carcinogen, according to results presented at the AACR Annual Meeting 2012, held here March 31 - April 4.

Safe method for destroying cancer cells using death cap mushroom poison

The mere thought of an identification error sends a chill down the spine of any mushroom lover: The death cap mushroom (Amanita phalloides), which resembles the common white button mushroom, contains one of the most deadly poisons found in nature, α-amanitin.

Targeting inflammatory pathways may lead to new therapies

Scientists at Fox Chase Cancer Center have uncovered more details about how defects in components of the machinery that makes new proteins can lead to blood and other cancers.

Genetic variations could be linked with meconium ileus in CF patients

University of North Carolina at Chapel Hill researchers working as part of the International Cystic Fibrosis Consortium have discovered several regions of the genome that may predispose cystic fibrosis (CF) patients to develop an intestinal blockage while still in the uterus.

Survivin protein could be a useful tool in understanding pancreatic cancer

Pancreatic cancer kills more than 40,000 people every year, and among cancers it's particularly insidious. For 80 percent of patients, the disease is already so advanced at the time of diagnosis that treatment is unlikely to provide significantly life-extending benefits. For patients diagnosed with localized pancreatic cancer, the five-year survival rate remains barely above 20 percent, according to the National Cancer Institute.

Scientists link two genes involved in serotonin production to PTSD

Why do some persons succumb to post-traumatic stress disorder (PTSD) while others who suffered the same ordeal do not? A new UCLA study may shed light on the answer.

Aberrations in translation regulators linked with hormone receptor-positive breast cancer survival

Four proteins involved in translation, the final step of general protein production, are associated with poor prognosis in hormone-receptor-positive breast cancer when they are dysregulated, researchers reported at the AACR Annual Meeting 2012.

French researchers find alcohol’s self regard boosting properties

Psychologists led by Laurent Begue at the Pierre-Mendes France University in the south-eastern city of Grenoble carried out an experiment. In the first stage, 19 drinkers, two-thirds of them men, were asked to assess their attractiveness on a scale of one to seven. Their alcohol levels were measured by a breath analyzer, and as expected, the higher the amount of alcohol that had been drunk, the rosier the self-assessment.

New breast cancer gene mutation discovered

A large international study led by University of Melbourne researchers has identified a mutation linked to breast cancer attached to the newly identified gene, called XRCC2. Lead researcher Melissa Southey said the discovery, using high-speed technology, would hopefully mean that more gene mutations responsible for causing breast cancer could be rapidly identified in the next few years.

Synthetic Marijuana banned in NY

Brands like “Mr. Nice Guy”, “Smiley Dog”, “K2”, “Spice”, “Galaxy Gold” and other brands of fake pot sold across the counter in convenience stores and tobacco shops face the ban. The ban was issued by New York State Health Commissioner Nirav Shah and his New York City equivalent with immediate effect.

Autism cases rise by 23% from ’06 to ’08: CDC report

According to latest figures, nearly one in 88 U.S. children have autism spectrum disorders. The report further urges national attention on the need for earlier diagnosis and treatment, especially in rural and minority communities.

Thermally content mice might serve as meaningful research subjects

Nine out of 10 drugs successfully tested in mice and other animal models ultimately fail to work in people, and one reason may be traced back to a common fact of life for laboratory mice: they're cold, according to a researcher at the Stanford University School of Medicine.
