Mice inhabiting an area known for its high concentration of asbestos-contaminated dust, have a higher level of genetic somatic mutations, compared with other regions where asbestos pollution levels are lower. This has been shown in a new study carried out by Dr. Rachel Ben-Shlomo and Dr. Uri Shanas of the University of Haifa's Department of Biology in Oranim. "This study clearly indicates that there is a link between the higher levels of asbestos in the environment and the frequency of genetic somatic mutations in the mammals," the scientists said.

SEATTLE – While people in Japan, Canada, and other nations are enjoying significant gains in life expectancy every year, most counties within the United States are falling behind, according to a new study by the Institute for Health Metrics and Evaluation (IHME) at the University of Washington.
IHME researchers, in collaboration with researchers at Imperial College London, found that between 2000 and 2007, more than 80% of counties fell in standing against the average of the 10 nations with the best life expectancies in the world, known as the international frontier.
Philadelphia, PA, June 15, 2011 – People generally worry about who their neighbors are, especially neighbors of our children. If high-fat food and soda are nearby, people will imbibe, and consequently gain weight. Or will they? With students' health at risk, a study in the July/August 2011 issue of the Journal of Nutrition Education and Behavior explores the influence food store locations near schools has on the student risk of being overweight and student fast-food and sweetened beverage consumption.
Philadelphia, PA, June 15, 2011 – According to the United States Department of Health and Human Services' Healthy People 2010 objectives, adequate fruit and vegetable consumption is a national public health priority for disease prevention and maintenance of good health. Not only do fruits and vegetables furnish valuable dietary nutrients, but they also contribute vital elements to chronic disease prevention for heart disease, hypertension, certain cancers, vision problems of aging, and possibly type 2 diabetes.
Alexandria, VA — A multidisciplinary clinical practice guideline, "Polysomnography for Sleep-Disordered Breathing Prior to Tonsillectomy in Children" will be published as a supplement to the July issue of Otolaryngology—Head and Neck Surgery. This guideline provides otolaryngologists with evidence-based recommendations for using polysomnography in assessing children, aged 2 to 18 years, with sleep-disordered breathing and who are candidates for tonsillectomy, with or without adenoidectomy.
DALLAS – June 15, 2011 – A pediatric urologist at UT Southwestern Medical Center who pioneered a surgical technique for repairing a common birth defect in boys reports the procedure is singularly effective in correcting the problem with few complications.
Hypospadias, the second most common birth defect in boys, causes the opening of the urethra to be misplaced on the penis. If not corrected properly, the malady can lead to urinary tract infections and difficulty with urination and normal sexual activity.
People who use a mist inhaler to deliver a drug widely prescribed in more than 55 countries to treat chronic obstructive pulmonary disease (COPD) may be 52 percent more likely to die, new Johns Hopkins-led research suggests.
The main causes of increases in blood pressure over a lifetime are modifiable and could be targeted to help prevent cardiovascular disease: although high blood pressure sometimes has no obvious symptoms, this condition, which affects about a third of the adult UK and US populations, can lead to life-threatening heart attacks and stroke, so reducing blood pressure is very important for health.
HIV prevention activities aiming to reduce incidence could be targeted more effectively and efficiently if a quick, easy, valid, and precise method of estimating incidence in populations were available. These are the conclusions of a group of international experts convened to discuss the challenges and progress in the field, with the aim of stimulating new investment in technologies for identifying recent HIV infections.
In the fifth article of a six-part PLoS Medicine series on migration & health, Zachary Steel from the University of New South Wales in Sydney, Australia and colleagues discuss the health risks associated with "interception strategies" that are used by governments to control and order international migration, especially in terms of halting the movement of irregular migrants, including asylum seekers.
Genes control everything from eye color to disease susceptibility, and inheritance - the passing of the genes from generation to generation after they have been duplicated - depends on centromeres. Located in the little pinched waist of each chromosome, centromeres control the movements that separate sister chromosomes when cells divide ensuring that each daughter cell inherits a complete copy of each chromosome. It has long been known that centromeres are not formed solely from DNA; rather, centromere proteins (CENPs) facilitate the assembly of a centromere on each chromosome.
Grand Rapids, Mich. (June 14, 2011) – In a study recently published in Cancer Research, Van Andel Research Institute (VARI) researchers found a protein that could help predict the spread of the head and neck cancer nasopharyngeal carcinoma (NPC); this protein could also serve as part of a treatment strategy to stop the spread of the disease.
ANN ARBOR, Mich. – Government guidelines published today on the use of dried blood spots collected during mandatory newborn screening underemphasize the importance of getting the public on board with the practice, according to University of Michigan researcher.
WEST LAFAYETTE, Ind. - The interaction between a Hessian fly's saliva and the wheat plant it is attacking may be the key to whether the pest eats like a king or dies like a starving pauper, according to a study done at Purdue University.
Cancer is crafty. When one avenue driving its growth is blocked by drugs targeting that path, the malignancy often creates a detour, finding an alternative route to get around the roadblock.
