NOW LASERS CAN CONTROL HEART BEAT NON-INVASIVELY…..A NEW BREAKTHROUGH

Researchers pace embryonic heart with laser

Love, exercise and, new research shows, an infrared laser can make a heart beat faster.

Scientists at Case Western Reserve University and Vanderbilt University found that pulsed light can pace contractions in an avian embryonic heart, with no apparent damage to the tissue. The work, “Optical pacing of the embryonic heart,” will be published in the advanced online issue of Nature Photonics on Aug. 15, 2010.

According to the scientists, this non-invasive device may prove an effective tool in understanding how environmental factors that alter an embryo’s heart rate lead to congenital defects. It may also lead to investigations of cardiac electrophysiology at the cellular, tissue and organ levels, and possibly the development of a new generation of pacemakers.

REDUCE WEIGHT TO CURB DIABETES

Scientists have been searching for a cure for diabetes for long, and now they have indications that it may be lurking somewhere in the stomach. Doctors have found that several diabetics who underwent bariatric surgery (stomach reduction) to treat obesity, have shown reduction in blood sugar levels. Now, they are studying the unforeseen positive impact of the surgery to see if a drug could be developed to mimic the effect of a reduced stomach. Quoting studies from Sweden, US and UK, London-based Dr Torsten Olbers, senior consultant, Imperial College, London said diabetics had been cured in many patients over a period of time and in several others there was a substantial improvement in the quality of life. “There have been cases of diabetics (type-2) not needing insulin after a bariatric surgery. Some may take time, while several others need to take only lower doses of insulin after ,” said Dr Olbers who is on a visit to the city. Dr Olbers will be speaking on the effects of bariatric surgery at a workshop organised by Apollo Hospitals on Saturday. Type-2 diabetes, a lifestyle disorder, is usually triggered by obesity and it becomes difficult to maintain sugar levels even with insulin if patients do not lose weight. As a last resort for weight management, one of the three most common bariatric procedures band, bypass or sleeve is performed where the volume of the stomach is reduced intake by at least 80%. Delhi-based diabetologist Dr Anoop Misra says the observation makes sense. “Bariatric surgery results in reduction of agents in the stomach that stimulates appetite. Moreover, it increases some other secretions of the intestine that aid better absorption of insulin,” he says. Dr Prasanna Kumar Reddy of Apollo Hospitals cites the case of his patient M Gowtham. Weighing 163kg, Gowtham had diabetes and hypertension before he underwent a bariatric surgery. “Not only that his weight has come down to 93 kg, his blood sugar has also stabilised without insulin injections,” said Dr Reddy. “I feel like a normal human being now. I do everything I have been just wanting to do for the past 20 years,” said Gowtham. Having seen several such cases, Dr Abeezar Sarla, senior lecturer in surgery at the University of Leeds, said bariatric surgeons should be called metabolic surgeons. Considering the increasing population of people with both obesity and diabetes, it would soon be a common surgery. However, surgeons warn that patients should be chosen carefully for the surgery. “It’s not a surgery for people with normal weight. And there are risks associated with it. At least one in 20 patients can develop complications like bleeding and leakage. It could cause death in one in 500 patients, a risk comparable to any other surgery. And in some people there is even resurgence of obesity,” said Dr Olbers.
