Immune system has protective memory cells, researchers discover

The immune system possesses a type of cell that can be activated by tissues within the body to remind the immune system not to attack our own molecules, cells and organs. The discovery is likely to lead to new strategies for fighting a range of autoimmune diseases -- in which the immune system attacks and harms specific molecules and cells within us -- as well as for preventing transplant rejection, according to UCSF researchers who report their findings in the November 27 online edition of the journal Nature.

Dietary treatment of epilepsy: rebirth of an ancient treatment.

Since its introduction in 1921, the ketogenic diet has been in continuous use for children with difficult-to-control epilepsy. Modifications that help improve tolerability include the medium chain triglyceride diet, modified Atkins diet, and low glycemic index treatment. Side effects include acidosis, increased cholesterol, kidney stones, gastroesophageal reflux, and growth disturbance, although these are manageable.

Study demonstrates a connection between a common chemical and Parkinson's disease

A University of Kentucky faculty member is a contributing author on a new study demonstrating a connection between a common solvent chemical and Parkinson's disease. Dr. Franca Cambi of the UK Kentucky Neuroscience Institute collaborated with researchers from across the U.S. on a paper recently published in the Annals of Neurology. The novel study looked at a cohort of human twins wherein one twin had been occupationally exposed to trichloroethylene (TCE) and other chemicals believed to be linked to development of Parkinson's.

"Our results show that: (i) children from countries with the highest ASD prevalence appear to have the highest exposureto Aluminium from vaccines; (ii) the increase in exposure to Aluminium adjuvants significantly correlates with the increase in Autism spectrum disorder prevalence in the United States observed over the last two decades ; and (iii) a significant correlation exists between the amounts of Al administered to preschool children and the current prevalence of ASD in seven Western countries, particularly at 3-4months of age . The application of the Hill's criteria to these data indicates that the correlation between Aluminium in vaccines and ASD may be causal".

Future obesity may be predicted at 3.5 years of age

Researchers can predict which children are most likely to become obese by examining their mothers' behaviour around their birth, according to a recent University of Montreal study published in the Archives of Pediatric and Adolescent Medicine. "Although behaviour is extremely hard to change and is also influenced by a complex tangle of influencing factors in the environment, I hope these findings will help improve the social and medical services we offer to mothers and infants," said lead author Laura Pryor, a PhD candidate at the university's Department of Social and Preventive Medicine. The findings come as the province of Quebec, like other societies, grapples with a surge in childhood obesity over the last generation.
