Promising Parkinson's Drug in Pipeline

A drug designed to treat high blood pressure also diminishes the debilitating symptoms of Parkinson's disease in mice, a study published Thursday has reported.

Because the drug, isradipine, has already been approved for human use, it could soon be available for Parkinson's patients, the lead researcher told AFP.

Gene Mutation Discovery Could Affect Leukemia Treatment

Mutations in a single gene can predict whether leukemia patients will suffer a more severe form of the disease, said a study released Wednesday that could change treatment for the blood cancer.

Patients with the gene mutation lived for a median of just over one year, while those without it lived for a median of three and a half years, according to the study in the November 11 issue of the New England Journal of Medicine.

Bilingualism Delays Onset of Alzheimer's

Speaking two languages can help delay the onset of Alzheimer's symptoms by as long as five years, Canadian scientists said.

The Baycrest's Rotman Research Institute researchers examined clinical records of 211 patients diagnosed with Alzheimer's disease and found that those who spoke two or more languages consistently over many years experienced a delay in the onset of their symptoms by as long as five years.

Aggressive Use of Statins Further Cuts Cardio Risk

Higher doses of statins cut the risk of heart attacks and stroke by one-seventh compared with regular statin treatment, according to a review published online on Tuesday by The Lancet.

The study looked at five trials in which around 40,000 patients, advised to lower their levels of blood cholesterol, received either regular statin treatment or intensive treatment.

Scientists Turn Skin into Blood

Stem cell researchers have found a way to turn a person's skin into blood, a process that could be used to treat cancer and other ailments, according to a Canadian study published Sunday.

The method uses cells from a patch of a person's skin and transforms it into blood that is a genetic match, without using human embryonic stem cells, said the study in the journal Nature.

New Polio Vaccine Raises Hope for Eradication

A new polio vaccine offers superior immunization and is raising hopes of a total eradication of the disease, according to a study published on Tuesday by British medical journal The Lancet.

There are three types of the polio virus, and while type 2 has been almost entirely eradicated since mass vaccinations began in 1988, types 1 and 3 remain a global health threat.

Stemcells Coaxed to Rebuild Bone, Cartilage

Scientists have shown for the first time that it may be possible to replace a human hip or knee with a joint grown naturally inside the body using the patient's stem cells.

In experiments on rabbits, the researchers coaxed the animals' stem cells to rebuild the bone and cartilage of a missing leg joint, according to a study published on Thursday.
