Joint pain in children: Is it just a sore knee, or could it be juvenile idiopathic arthritis? (March 2, 2011) -- While lab tests and imaging can sometimes help diagnose juvenile idiopathic arthritis, a physical examination and thorough patient history are the most valuable tools in identifying this disease. ... > full story
Effectiveness of wastewater treatment may be damaged during a severe flu pandemic (March 2, 2011) -- Existing plans for antiviral and antibiotic use during a severe influenza pandemic could reduce wastewater treatment efficiency prior to discharge into receiving rivers, resulting in water quality deterioration at drinking water abstraction points, according to a new article. ... > full story
Amyotrophic lateral sclerosis (ALS) could be caused by a retrovirus, study suggests (March 2, 2011) -- A retrovirus that inserted itself into the human genome thousands of years ago may be responsible for some cases of the neurodegenerative disease amyotrophic lateral sclerosis (ALS), also known as Lou Gherig's disease. The finding may eventually give researchers a new way to attack this universally fatal condition. ... > full story
Researchers predict age of T cells to improve cancer treatment (March 2, 2011) -- The effectiveness of the cancer therapy known as adoptive T cell transfer is limited by the cells' finite lifespan. Researchers have now addressed this limitation by accurately predicting cell age and quality. Infusing only young functional cells into a patient should improve the therapeutic outcome. ... > full story
Hair dyeing poised for first major transformation in 150 years (March 2, 2011) -- Technological progress may be fast-paced in many fields, but one mundane area has been almost left in the doldrums for the last 150 years: The basic technology for permanently coloring hair. That's the conclusion of an analysis of almost 500 articles and patents on the chemistry of permanent hair dyeing, which foresees much more innovation in the years ahead, including longer lasting, more-natural-looking dyes and gene therapy to reverse the gray. ... > full story

Shift work may be associated with decreased risk of skin cancer (March 2, 2011) -- Melatonin is known to have cancer-protective properties, and shift work can induce desynchrony of the circadian system, reducing melatonin production. Shift work has been thought to have important health impacts, with evidence linking shift work to an increased risk of several cancers including breast, endometrial, prostate and colorectal, and non-Hodgkin lymphoma. In a recent study, researchers found that shift work may be associated with a reduced risk of skin cancer in women. ... > full story
Nitric oxide does not appear to improve treatment of sickle cell pain-attacks (March 2, 2011) -- Among patients with sickle cell disease, treatment of a vaso-occlusive crisis (characterized by episodes of severe pain) in the hospital with inhalation of nitric oxide gas for up to 3 days did not result in a shorter time to resolution of the pain, compared to patients who received placebo, according to a new study. ... > full story
Cements that self-repair cracks and store latent heat energy? (March 2, 2011) -- Cement (and derivatives thereof) is one of the materials most commonly used in construction, given its good performance at low cost. Over recent years, one part of scientific and technological research is aimed at incorporating additional functions into these materials.
