CT enteroclysis should replace conventional enteroclysis in patients with Crohn's disease

The diagnostic value of CT enteroclysis is superior to conventional enteroclysis, previously considered the gold standard, as an imaging method for the evaluation of the small bowel in patients with Crohn's disease, a new study shows.

Common cardiac sodium channel variant associated with sudden infant death in African Americans

Steve A.N. Goldstein and colleagues from the Pritzker School of Medicine in Chicago have found that a specific mutation, called S1103Y, in a heart protein known as SCN5A is associated with a dramatic, 24-fold increased risk of sudden infant death syndrome (SIDS) in African American infants.

Eosinophilic esophagitis gene discovery

Researchers at Cincinnati Children's Hospital Medical Center have discovered the first gene associated with eosinophilic esophagitis, one of a number of eosinophil-related diseases in which the body produces abnormally large amounts of white blood cells that can lead to allergy related illnesses.

Two-drug treatment could help asthma and chronic bronchitis sufferers

Current treatments for asthma and chronic bronchitis aren't able to address the ultimate source of the problem--they can only alleviate symptoms.

Can marriages be saved by treating snoring?

The husband snores. The wife nudges him to flip over. Both wake up feeling grouchy the next morning. It's a common occurrence that may have more of an impact on the marriage than most couples think.

PET imaging has the potential to improve cancer care management

A limitation of current cancer care is the difficulty of quickly assessing how well a therapy is working. However, expanding the use of existing positron emission tomography (PET) technology can provide early and accurate assessment of a tumor's response to a particular therapy allowing physicians to better tailor a patient's treatment

miRNA emerge as a class of gene regulators

Scientists have discovered that a wide variety of different cancers actually share something in common - a molecular "signature" made up of tiny bits of genetic material called microRNA (miRNA) that target key cancer genes and promote malignant growth.

Pain sensitivity is enhanced when people are thirsty

Researchers at Melbourne's Howard Florey Institute have discovered how the brain prioritises pain and thirst in order to survive - a mechanism that helps elite athletes to 'push through the pain barrier'.

Babies fully breastfed for six months less likely to suffer from respiratory illnesses

Babies fully breastfed for six months are less likely to suffer from respiratory illnesses in their first two years than babies fully breastfed for only four months, according to research conducted by investigators at UC Davis Children's Hospital, the University of Rochester and the American Academy of Pediatrics, Center for Child Health Research.

Chronic disease is becoming a major focus in health care

More funding, increased workforce resources and further reform of the health system are needed if the national chronic disease strategy is going to deliver better care to patients suffering from diseases such as diabetes, asthma and cancer, according to an international primary health expert.

Link between dementia and cancer

By expressing a protein associated with Alzheimer's disease in the brain of the fruit fly, researchers have demonstrated an intriguing link between neuronal death and proteins previously associated with cancer.

New insight into one of the fundamental features of evolution

By experimentally promoting rapid, small-scale evolution within a lab population of yeast, researchers have shed light on the kinds of genetic changes that may underlie the emergence of new species.

Mediterranean diet may reduce the risk of cardiovascular disease in patients with metabolic syndrome

Nearly 50 million Americans have metabolic syndrome, a cluster of risk factors placing them at increased risk of developing cardiovascular disease.

Soy's cardiovascular benefits may have been overestimated

Many soy food products carry health claims stating that they reduce the risk of heart disease. A review of the evidence, however, suggests that soy's cardiovascular benefits may have been overestimated by the early studies that formed the basis for its health claim.

Diet rich in whole-grain foods may lower heart disease risk in elderly people

With the recent revision of the Food Guide Pyramid, the Dietary Guidelines for Americans have for the first time provided the public with a quantitative recommendation for whole-grain intake.

Abraham Lincoln may have suffered from movement disorder

Researchers at Johns Hopkins and the University of Minnesota have discovered a gene mutation in the descendants of Abraham Lincoln's grandparents that suggests the Civil War president himself might have also suffered from a disease that destroys nerve cells in the cerebellum-- the part of the brain that controls movement.

Teens' healthy food choices foiled by early lunch

Penn State researchers have identified three previously unreported factors that foil the efforts of high school students to make healthy food choices - early lunch, school income from soft drink incentives, and parents who bring fast food to the cafeteria for their kids.

DNA end caps may lead to cancer treatments

The two ends of human DNA have different structures that are treated differently as a cell divides, UT Southwestern Medical Center researchers have found in a study that could help lead to cancer therapies.

Myosin VI can act as molecular transporter

Myosin VI has been thought to be a monomer, but Park et al. show that full-length myosin VI can be a dimer, and can walk processively on actin. By increasing the concentration, a greater and greater fraction dimerizes in vitro, and walks processively on actin.
