Ingestion of commonly encountered nanoparticles at typical environmental levels is unlikely to cause overt toxicity, according to US researchers. Nevertheless there is insufficient evidence to determine whether chronic exposures could lead to subtle alterations in intestinal immune function, protein profiles, or microbial balance.

Across sub-Saharan Africa, women and children play major roles as pedestrian load-transporters, in the widespread absence of basic sanitation services, electricity and affordable/reliable motorised transport.

Professor Kim Buton of the University of Huddersfield, has coauthored an international study to look at the health impacts that this practice can have.

LOS ALAMOS, N.M., and MARINA DEL REY, Calif., June 26, 2013 — Los Alamos National Laboratory and Tribogenics, the pioneer of innovative X-ray solutions, have partnered to create a unique, lightweight, compact, low-cost X-ray system that uses the MiniMAX (Miniature, Mobile, Agile, X-ray) camera to provide real-time inspection of sealed containers and facilities. The innovative technology will be featured at the International Atomic Energy Agency (IAEA) International Conference on Nuclear Security: Enhancing Global Efforts, July 1-5, in Vienna, Austria.

Gliomas are malignant brain tumors that arise from glial cells called astrocytes, found in the central nervous system. "In treating malignant gliomas, we currently combine radiotherapy with the anticancer drug temozolomide. However, in some patients, tumors rapidly become resistant to both treatment methods," says neurooncologist Professor Dr. Michael Platten, who leads a cooperation unit of the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) and the Department of Neurooncology of Heidelberg University Hospital.

In 2011 and 2012, research from China's Nanjing University made international headlines with reports that after mice ate plants, bits of genetic material from the plants they'd ingested could make it into their bloodstreams intact and turn the animals' own genes off. The surprising results from Chen-Yu Zhang's group led to speculation that genetic illness might one day be treated with medicinal food, but also to worry that genetically modified foods might in turn modify consumers in unanticipated ways.

DETROIT — A Wayne State University researcher has found that sleep apnea severity is higher among African-American men in certain age ranges, even after controlling for body mass index (BMI).

A study by James A. Rowley, M.D., professor of internal medicine in WSU's School of Medicine, showed that being an African-American man younger than 40 years old increased the apnea-hypopnea index (AHI) by 3.21 breathing pauses per hour of sleep compared to a white man in the same age range with the same BMI.

Someone finds that piece of chewing gum you pitched today, uses the saliva to sequence your DNA and surreptitiously reads your book of life — including genetic secrets like your susceptibility to diseases. If that scenario, posed in an article in the current edition of Chemical & Engineering News, causes a little discomfort, consider this: That stranger also uses the DNA to reconstruct a copy of y-o-u.

BOSTON (June 26, 2013)-- Community wide interventions hold promise as an effective approach to reducing childhood obesity rates according to new research from the Friedman School of Nutrition Science and Policy at Tufts University and Tufts University School of Medicine. An analysis of data from the first two school years (20 calendar months) of the Shape Up Somerville: Eat Smart Play Hard™ intervention showed that schoolchildren in Somerville, Massachusetts gained less weight and were less likely to be obese or overweight than schoolchildren in two similar control communities.

Distal radius fractures (often simply termed wrist or Colles' fractures) are the second most common fractures in the elderly. Beyond the immediate impact on the patient, wrist fractures in older adults often indicate underlying osteoporosis and high risk of subsequent fragility fractures.

Scientists are reporting progress in the search for the first broad-spectrum drugs to combat human rhinoviruses (HRVs), which cause humanity's most common infectious diseases. Their study on these potential drugs for infections that include the common cold appears in the journal ACS Medicinal Chemistry Letters.

While the iPad® is being used for intraoperative procedure guidance, percutaneous procedure planning, and mobile interpretation of some imaging examinations, the majority of radiology residents are using it primarily as an educational tool, according to a study published online in the Journal of the American College of Radiology.

The knees are the body part that is injured the most by dinghy sailors. The injuries are primarily due to overstrain and most often occur during physical training. This was shown in a study at Sahlgrenska Academy, University of Gothenburg, Sweden.

"Studies have been made on the risk of injury for many sports, but not for dinghy sailing. With more knowledge, we can create recommendations that will prevent sailors from getting injured," says Lena Bøymo-Having, who conducted the study at the Sahlgrenska Academy, University of Gothenburg.

Having a job helps women with HIV manage their illnesses, according to researchers from Case Western Reserve University and the University of California at San Francisco.

The routine of a work schedule, plus the job-related money and benefits, provides extra emotional support for these women, said Allison Webel, assistant professor of nursing at Case Western Reserve University's Frances Payne Bolton School of Nursing and the study's lead author.

Bethesda, MD (June 26, 2013) — More people are being affected by drug-induced liver injury (DILI) than ever before, according to a new study in Gastroenterology, the official journal of the American Gastroenterological Association. This type of liver injury results from the use of certain prescription and over-the-counter medications, as well as dietary supplements, and is among the more challenging forms of liver disease due to its difficulty to predict, diagnose and manage.

Contrary to popular belief, crabgrass does not thrive in lawns, gardens and farm fields by simply crowding out other plants. A new study in ACS' Journal of Agricultural and Food Chemistry has found that the much-despised weed actually produces its own herbicides that kill nearby plants.
