Increased allergen levels in homes linked to asthma

Results from a new national survey demonstrate that elevated allergen levels in the home are associated with asthma symptoms in allergic individuals. The study suggests that asthmatics that have allergies may alleviate symptoms by reducing allergen exposures inside their homes. more  

Changes in adult stem cells may underlie rare genetic disease associated with accelerated aging

Adult stem cells may provide an explanation for the cause of Hutchinson-Gilford Progeria Syndrome (HGPS), a rare disease that causes premature aging in children, according to researchers at the National Cancer Institute (NCI), part of the National Institutes of Health (NIH). more

New test for joint infection could spare some patients an unnecessary procedure

A potential diagnostic test that could help surgeons confirm or rule out the presence of infection-causing bacteria in prosthetic joints that require surgical revision has been developed by researchers at the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), a part of the National Institutes of Health (NIH). more  

'Innocent bystanders' can be the cause of tumor development

Tumor growth has commonly been viewed as a result of mutations in a given cell that will therefore proliferate uncontrollably. However, a study conducted at the University of Helsinki, Finland, has demonstrated that in certain type of gastrointestinal polyps, the cause of tumor development are mutations in the smooth muscle cells, previously regarded as “innocent bystanders”. more

Arsenic aids tumor imaging when joined to cancer-homing drug, UT Southwestern researchers find 

Arsenic linked to a drug that binds to the blood vessels of cancerous tumors provides a powerful imaging agent that could one day allow physicians to detect hard-to-find tumors and more closely monitor cancer’s response to therapy, researchers at UT Southwestern Medical Center have found. more

A nano-sensor for better detection of Mad Cow Disease agent

In an advance in food safety, researchers in New York are reporting development of a nano-sized sensor that detects record low levels of the deadly prion proteins that cause Mad Cow Disease and other so-called prion diseases. The sensor, which detects binding of prion proteins by detecting frequency changes of a micromechanical oscillator, could lead to a reliable blood test for prion diseases in both animals and humans, the researchers say. more
