Study adds to evidence that autism has genetic basis
Although there is no known cause of autism, studies have shown that mutations in several genes are associated with the developmental brain disorder.

Treatment plan for children with autism often includes complementary therapies
Complementary and alternative medicine (CAM) is becoming a popular treatment for a variety of conditions, with national data showing it is used by about 12 percent of children.

'Junk DNA' drives cancer growth
Researchers from the University of Leeds, UK, the Charité University Medical School and the Max Delbrück Centre for Molecular Medicine in Berlin, Germany, have discovered a new driving force behind cancer growth.

New studies examine adverse outcomes associated with obesity and more applicable measures of obesity
Pay-for-performance reimbursement models may create unintended financial incentives for doctors to discriminate against obese patients, measuring a patient's waist circumference may be more effective in predicting surgical outcomes than the more traditional body mass index measure, and childhood obesity doubles the risk of developing colon cancer, according to data being presented at Digestive Disease Week 2010.

Transplant drug 2-year study outcomes show superior kidney function
Two-year results from phase III clinical trials show the experimental immunosuppressive drug belatacept can better preserve kidney function in kidney transplant recipients while preventing graft rejection when compared with the standard immunosuppressive drug cyclosporine.

MicroRNA network study implicates rewired interactions in cancer
Genes interact in complex networks that govern cellular processes, much like people connect a social network through relationships.

CSIRO telescope spots mega-star cradle
Using a CSIRO radio telescope, an international team of researchers has caught an enormous cloud of cosmic gas and dust in the process of collapsing in on itself -- a discovery which could help solve one of astronomy's enduring conundrums:

Discrimination is associated with depression among minority children
Minority children often encounter racism in their daily lives, and those who experience discrimination more often have more symptoms of depression.

Pitt pharmacologists go on a molecular fishing trip and hook prize catch
Scientists at the University of Pittsburgh School of Medicine went on a molecular fishing trip and netted a catch of new mediators that not only can explain how omega-3 fatty acids reduce inflammation, but also hint at novel treatments for a host of diseases linked to inflammatory processes.

Researchers make advances in understanding causes, treatments and outcomes of liver disease
Nonalcoholic fatty liver disease (NAFLD), which may soon be the leading indication for liver transplant, is found to be significantly associated with worse transplant outcomes.

New free hand ultrasound system improves work flow and reduces scan time
Researchers have developed an automated 3-D mapping and labeling system that reduces scan time and improves the work flow, efficiency and accuracy of routine freehand ultrasound exams, according to a study to be presented at the ARRS 2010 Annual Meeting in San Diego, Calif.

Resurrected mammoth blood very cool
A team of international researchers has brought the primary component of mammoth blood back to life using ancient DNA preserved in bones from Siberian specimens 25,000-43,000 years old.

Families caught in the middle
When the high cost of health care forces families to forgo paying for basic household expenses, such as rent, utilities or food, children's health suffers.

Scripps Research team provides groundbreaking new understanding of stem cells
In findings that could one day lead to new therapies, researchers from the Scripps Research Institute have described some striking differences between the biochemistry of stem cells versus mature cells.

Cancer cells show rewired, fragmented microRNA networks
This new study shows that in healthy cells molecules of microRNA work together in single, well-connected networks that resemble a family tree with dozens to hundreds of members.

Children living with relatives struggle with physical, mental health issues
It is well-known that children in foster care are at increased risk for physical and mental health problems.

Expert panel to discuss autism spectrum disorders
A panel of experts will discuss the newest advances and research findings in the identification and treatment of ASD from 8 to 10 a.m.

Extended hepatitis C treatment after liver transplant may benefit patients
Extending hepatitis C treatment for liver transplant patients beyond current standards results in high clearance rates of the hepatitis C virus from the blood, and a low relapse rate, according to a study by Henry Ford Hospital.

New Stanford tool enables wider analyses of genome 'deep sequencing'
A new Stanford-developed, Web-based algorithm allows scientists to plumb the unprecedented depths of the data provided by new

Study shows liver transplant center impacts patient outcomes
For patients in need of a liver transplant, their choice of a transplant center can make a noteworthy difference in their outcomes, according to a Mayo Clinic study presented at the American Transplant Congress under way May 1-5 in San Diego.

Gene find offers hope of screening test for bone disease
Scientists have discovered three genes linked to the development of Paget's disease, a painful bone condition that affects up to one million people in the UK.

ASGE and ASGE Foundation hold Crystal Awards dinner at Digestive Disease Week
The American Society for Gastrointestinal Endoscopy will honor important contributions to the field of endoscopy during the sixth annual ASGE Crystal Awards on Sunday, May 2, 2010.

Children may be able to eat before cholesterol test, study shows
Physicians usually ask children to fast overnight before a cholesterol test.

Children with autism frequently receive psychotropic medications
Research conducted by Autism Speaks' Autism Treatment Network shows that use of psychotropic medications is common among children with ASD, with 27 percent of those enrolled in the network registry receiving at least one medication to manage their behavior.

The childhood obesity epidemic: How do we stop it?
Childhood obesity is a rapidly growing epidemic, but questions remain as to who can best prevent it -- the child?

Henry Ford Hospital study: Less prep needed for colonoscopy
Researchers at Henry Ford Hospital may have found a better way to prep patients for colonoscopy procedures so they no longer need to drink a gallon of prescribed fluids prior to the procedure.

Sleep disturbances associated with behavior problems in children with autism
Reports have suggested that sleep problems in children and adolescents with autism spectrum disorders (ASDs) are associated with challenging daytime behaviors.

New government pay-for-performance policies punish doctors who care for obese patients
Pay-for-performance reimbursement of surgeons, intended to reward doctors and hospitals for good patient outcomes, may instead be creating financial incentives for discriminating against obese patients, who are much more likely to suffer expensive complications after even the most routine surgeries, according to new Johns Hopkins research.

Older women with diabetes face higher risk for colon cancer
A research team led by Mayo Clinic physicians has found that older women with diabetes face a more than doubled risk for some types of colorectal cancer.

GI problems common in children with autism
A new study conducted by Autism Speaks' Autism Treatment Network shows that GI symptoms occur in nearly half of children with ASD, and the prevalence increases as children get older.
