Study finds smoking wards off Parkinson's disease

There is more evidence to back up a long-standing theory that smokers are less likely to develop Parkinson's disease than people who do not use tobacco products, researchers reported on Monday.

Pumpkin: A fairytale end to insulin injections?

Compounds found in pumpkin could potentially replace or at least drastically reduce the daily insulin injections that so many diabetics currently have to endure. Recent research reveals that pumpkin extract promotes regeneration of damaged pancreatic cells in diabetic rats, boosting levels of insulin-producing beta cells and insulin in the blood, reports Lisa Richards in Chemistry & Industry, the magazine of the SCI.

A group, led by Tao Xia of the East China Normal University, found that diabetic rats fed the extract had only 5% less plasma insulin and 8% fewer insulin-positive (beta) cells compared to normal healthy rats (Journal of the Science of Food and Agriculture, 87(9) 1753-7 2007).

Xia says: 'pumpkin extract is potentially a very good product for pre-diabetic persons, as well as those who have already developed diabetes.' He adds that although insulin injections will probably always be necessary for these patients, pumpkin extract could drastically reduce the amount of insulin they need to take.

New Diet Drug Touches Off a Feeding Frenzy

Boxes of Alli, the first FDA-sanctioned diet drug to be sold without a prescription, are selling in huge numbers, despite the fact that the pill comes with the potential for extremely unpleasant and embarrassing side effects.

The manufacturer has predicted that 5 million to 6 million Americans a year will buy the drug.

New fears over MMR link to autism; Damage Control shifts into high gear

Fresh fears over a possible link between the measles, mumps and rubella (MMR) vaccine and autism have been raised after a new study found that almost double the number of children could have the condition than previously thought.

CDC: Out of Excuses on the Autism Study that "Should be Done"

A simple study of autism rates among vaccinated and unvaccinated children "could be done and should be done" to help settle the raging debate that has now spilled into the U.S. Federal Courts.

Researcher sees link between vitamin D and autism

The growing prevalence of autism is one of the biggest scientific whodunits in the medical world, with few clues for its rising incidence.

But a U.S. researcher is advancing a controversial hypothesis: that autism is related to vitamin D deficiency during fetal development and early childhood.

From the corner of the eye: Paying attention to attention

Every kid knows that moms have "eyes in the back of their heads." We are adept at fixing our gaze on one object while independently directing attention to others. Salk Institute neurobiologists are beginning to tease apart the complex brain networks that enable humans and other higher mammals to achieve this feat.

In a study published in the July 5, 2007 issue of Neuron, the researchers report two classes of brain cells with distinct roles in visual attention, and highlight at least two mechanisms by which these cells mediate attention. "This study represents a major advance in our understanding of visual cognition, because it is the first study of attention to distinguish between different classes of neurons," says system neurobiologist John Reynolds, Ph.D., associate professor in the Systems Neurobiology Laboratory at the Salk Institute.

Chronic fatigue: clues in the blood

Researchers at UNSW believe that blood may hold vital insights into what is happening in the brain of patients with chronic fatigue syndrome (CFS).

In a study unparalleled in its scope, a team led by UNSW Professor Andrew Lloyd of the Centre for Infection and Inflammation Research, has studied the differences in gene expression patterns in the blood of people who either recover promptly after acute glandular fever or develop the prolonged illness called post-infective syndrome.

The researchers examined six million pieces of gene expression information for analysis in the project, known as the Dubbo Infection Outcomes Study. The study is named after the NSW town in which the work was conducted. The team studied the expression of 30,000 genes in the blood, testing each of the 15 individuals between four and five times over a 12-month period.

The team was able to narrow its findings to the expression of just 35 genes whose pattern of expression correlated closely with the key symptoms of the illness when examined from onset through to recovery. Gene expression is significant because it is the process by which a gene's DNA sequence is converted into the proteins which ultimately determine the manifestations of disease.

Organic food 'better' for heart

Organic fruit and vegetables may be better for you than conventionally grown crops, US research suggests.

A ten-year study comparing organic tomatoes with standard produce found almost double the level of flavonoids - a type of antioxidant.

Comment: So let's get this straight - food that is saturated in toxic substances such as industrial chemical fertilizers and pesticides actually leads to... less nutritious food? What a good job we have the clever scientists to tell us these things.
