A new study suggests that the addition of dried distillers' grain, an ethanol by-product, to cattle feed may contribute to the prevalence of E. coli O157 infection in cattle. The researchers from Kansas State University, Manhattan report their findings in the January 2008 issue of the journal Applied and Environmental Microbiology.

Being resistant to aspirin makes patients four times more likely to suffer a heart attack, stroke or even die from a pre-existing heart condition, according to a new study.

Researchers report on a new modality of treatment for bulimia nervosa, transcranial magnetic stimulation, in Psychotherapy and Psychosomatics. Transcranial magnetic stimulation is a non-invasive, neurophysiological method, which affects cortical neurons with a short magnetic pulse. Bulimia nervosa (BN) is often associated with depressive symptoms and treatment with antidepressants has shown positive effects.

Researchers have found that automated electronic medical laboratory reporting improves both the completeness and timeliness of disease surveillance, significantly bettering the odds of stopping the spread of disease.

In connection with last year's epidemic, a research team at Umea University in Sweden has managed for the first time to show that hantavirus exists in human saliva. This raises the question of whether this contagion can spread among humans.

A saline nasal wash solution made from processed seawater appears to improve nasal symptoms and may help prevent the recurrence of respiratory infections when used by children with the common cold, according to a new report.

In a study that may significantly advance the understanding of how cognitive-behavioral therapy affects the brain, researchers have shown that significant changes in activity in certain regions of the brain can be produced with as little as four weeks of daily therapy in patients with obsessive-compulsive disorder. The discovery could have important clinical implications.

Powerful drugs used to treat patients with rheumatoid arthritis have a profound, previously unrecognized effect on the immune system, breaking up molecular "training camps" for rogue cells that play an increasingly recognized role in autoimmune diseases like rheumatoid arthritis and lupus.

Researchers have discovered that proteins carrying chemical cargo in nerve cells react differently when exposed to the tau protein, which plays an important role in Alzheimer's disease.

Genome-wide scans of families affected by autism spectrum disorder have revealed new evidence that previously unknown chromosomal abnormalities have a substantial role in the prevalent developmental disorder.
