Acute anemia linked to silent strokes in children (February 12, 2011) -- Silent strokes, which have no immediate symptoms but could cause long-term cognitive and learning deficits, occur in a significant number of severely anemic children, especially those with sickle cell disease, according to newly presented research. ... > full story
Nanoparticles may enhance circulating tumor cell detection (February 12, 2011) -- Tiny gold particles can help doctors detect tumor cells circulating in the blood of patients with head and neck cancer, researchers have found. ... > full story
Even with fetal lung maturity, babies delivered prior to 39 weeks are at risk (February 12, 2011) -- Despite fetal pulmonary maturity, babies delivered at between 36 to 38 weeks, still have a significantly increased risk of neonatal morbidities. ... > full story
Kids with ADHD much more likely to develop substance abuse problems as they age, study finds (February 12, 2011) -- Children with attention deficit hyperactivity disorder (ADHD, or ADD) are two to three times more likely than children without ADHD to later develop serious substance abuse problems in adolescence and adulthood, report psychologists. ... > full story
Firefly glow: Scientists develop a hydrogen peroxide probe based on firefly luciferin (February 12, 2011) -- Scientists have developed a probe for monitoring hydrogen peroxide levels in mice that enables them to track the progression of cancerous tumors or infectious diseases without harming the animals or even having to shave their fur. This new probe is based on luciferase, the enzyme that gives fireflies their glow. ... > full story
Compound blocks brain cell destruction in Parkinson's disease; Findings may open door to first protective therapy (February 12, 2011) -- Scientists have produced the first known compound to show significant effectiveness in protecting brain cells directly affected by Parkinson's disease, a progressive and fatal neurodegenerative disorder. ... > full story
Leptin resistance may prevent severe lung disease in patients with diabetes (February 12, 2011) -- Resistance to leptin, a protein that plays a key role in regulating metabolism and appetite, may help prevent the development of acute respiratory distress syndrome (ARDS) and acute lung injury (ALI) in individuals with type II diabetes, according to a study conducted by researchers in Chicago. The study indicates leptin resistance, a common characteristic of diabetes, may help prevent the formation of inflexible, fibrous tissue that develops in ALI and ARDS. ... > full story
Scientists hope to cut years off development time of new antibiotics (February 12, 2011) -- Eliminating tens of thousands of manual lab experiments, researchers are working toward a method to cut the development time of new antibiotics. A computerized modeling system they're developing will speed up the often decade-long process. Pharmacy professors and engineering professors are focusing on dosing regimens to reveal which ones are most likely to be effective in combating infection and which are not worth pursuing. ... > full story
In online dating, blacks more open to romancing whites than vice versa, study finds (February 12, 2011) -- Has Valentine's Day become post-racial? Not yet, it seems. New research suggests that when it comes to dating, cyberspace is as segregated as the real world. Data gathered from more than 1 million profiles of singles looking for love online show that whites overwhelmingly prefer to date members of their own race, while blacks, especially men, are far more likely to cross the race barrier in hopes of being struck by Cupid's arrow. ... > full story
New drug treatment possibilities for Alzheimer's (February 11, 2011) -- Scientists have made a discovery that has the potential for use in the early diagnosis and eventual treatment of plaque-related diseases such as Alzheimer's disease and type 2 diabetes. ... > full story
New way to attack pathogens: RNA recycling system gone awry brings MRSA to a halt (February 11, 2011) -- Scientists have discovered a new way to attack dangerous pathogens, marking a hopeful next step in the ever-escalating battle between man and microbe. By stopping bacteria's ability to degrade RNA -- a "housekeeping" process crucial to their ability to thrive -- scientists were able to stop methicillin-resistant Staphylococcus aureus or MRSA both in the laboratory and in infected mice. The approach shows promise against the most severe strains of the bacteria as well as MRSA biofilms. ... > full story
Experts urge even greater caution in use of X-rays during pregnancy and infancy (February 11, 2011) -- Clinicians should be careful about using X-rays on pregnant women and infants because of the potential for a slight increase in the risk of children developing cancer, concludes a new study. ... > full story
