what's the buzz


An international team, led by Indian-origin researcher Dr Kiran Ahuja, Tasmania University, has found that chillies have the potential to prevent diabetes and cardiovascular disease, the leading cause of morbidity and mortality in many countries.
The study has found that two active ingredients of chillies, capsaicin and dihydrocapsaicin, have the potential to lower blood glucose and insulin levels, reduce formation of fatty deposits on artery walls and prevent blood clots.
The researchers have found that eating a meal containing chillies lowered post-meal blood glucose and insulin concentrations. High levels of glucose and insulin are linked to an increased risk for the development of diabetes.
The study revealed chillies help reduce the oxidation of LDL-cholesterol and therefore reduces the chance of plaque formation in the arteries.

Men too turn to crash dieting
It’s not just women who spend half of lives obsessing over their figures, men too have joined the ladies in their weight-loss bandwagon, reveals a new UK poll.
Almost half of British men are desperate to slim and have turned to crash and fad dieting and slimming pills in the bid for a perfect body, says the poll.
The study found that one in three worry about their calorie count at a night in the pub.
They are more worried about emulating the toned bodies they see on magazine covers than with being healthy. Only 13 per cent were worried by rising heart rates and cholesterol, the study revealed.

Hip replacements can be prevented
British surgeons at the Spire Hospital in Southampton are using a novel technique that uses stem cells to repair damaged bones. The procedure may prevent thousands of people from needing to have an artificial hip fitted.
Mark Venables, 39, is one patient on whom doctors conducted one of their first operations. He suffers from a condition where bone in his hip died, weakening his joint and causing pain on movement. The surgeons used his own stem cells to rejuvenate the affected bone.
For the operation, the surgeons first purified stem cells from bone marrow that they had extracted from Venables’ pelvis. The doctors then mixed them with cleaned, ground-up bone from another patient, who had had their own hip replaced. After removing the dead tissue from the ball of his hip, the doctors filled the cavity with the mixture of stem cells and donated bone.

A simple test to diagnose MS
Scientists from University College London have revealed that a simple blood test may soon help predict the severity of multiple sclerosis (MS).
Lead researcher Rachel Farrell says that a biological marker in blood appears to be linked to a patient’s prognosis after the first MS attack.
If a blood test based on the biomarker can be validated, it could be used with MRI scans and other methods to improve accuracy and assess an individual’s likely prognosis.
During the study, the researchers investigated links between MS and Epstein Barr Virus (EBV), a virus to which about 90 per cent of people have been exposed.
