Yoga and stroke rehab

People who have balance problems following a stroke can benefit from yoga classes.

Stroke patients frequently suffer with balance problems a long time after they have, in all other ways, recovered. This obviously poses a health risk as imbalance can lead to accidents. In a study at Indiana University, 47 people, most of them US army veterans who had all had a stroke at least six months previously, performed various activities.

One third had yoga twice a week for eight weeks; another had yoga twice a week as well as access to a relaxation recording to use at least three times a week; the third group had no yoga at all. The classes involved relaxation, postures and meditation, with the skill level being increased each week.

Those who did yoga regularly had superior balance control after the eight weeks when compared to the control group. They also scored higher on tests for feelings of independence and quality of life. Because people only get rehabilitation care for a few months following a stroke, these findings are important as they indicate they could continue to benefit from yoga for a longer time period.


While many of us may shy away from trying yoga for fear of not being able to get into the pretzel-like positions experts achieve, it’s one of the few activities that you can get a lot out of whether you’re a beginner or advanced. Older people who practise yoga regularly are not only more supple, they also tend to have stronger bones and better muscle tone.

Grapefruit juice can enhance cancer drugs

A glass of grapefruit juice a day could indeed boost the efficacy of cancer drugs, check their side effects and also reduce the cost of the medication, according to a study.

Combining the fruit with a specific anti-cancer drug delivered the same benefits as patients would have from taking more than three times of the medication by itself.

University of Chicago researchers said the combination could help patients avoid side effects associated with high doses of the drug and reduce the cost of the medication, the journal Clinical Cancer Research reports.

Grapefruit juice is known to prevent enzymes in the intestine that break down certain drugs, meaning more can enter the blood stream, according to the Daily Mail.

Doctors often tell patients to avoid some fruits when taking particular medications as it can cause serious side-effects or overdose.

Scientists now wanted to see if they could harness this effect. Study leader Ezra Cohen said: “Grapefruit juice, and drugs with a similar mechanism, can significantly increase blood levels of many drugs.”

“But this has long been considered an overdose hazard. Instead, we wanted to see if grapefruit juice can be used in a controlled fashion to increase the availability and efficacy of sirolimus,” added Cohen.


Sirolimus or rapamycin is used to prevent rejection in organ transplantation but is also being tested as a treatment for certain tumours.

The Chicago team showed that patients who drank eight ounces of grapefruit a day increased their sirolimus levels by 350 percent. Certain substances in grapefruit juice are known to stop an enzyme in the small intestine from breaking down some medications.

This allows more of the drug to enter the blood stream, and could at one level cause serious side-effects or accidental overdose.
