Indian scientists discovered insulin pills for diabetics

December 21, 2013

Indian scientists have discovered a pill form of insulin treatment,  so nowdiabetes patients would be spared from the pain of jabbing themselves with a needle every day.

The process to transform delivery of this therapy from a shot to a pill was a challenge because body’s digestive enzymes that are so good at breaking down food also break down insulin before it can get to work. Besides, insulin doesn’t get easily absorbed through the intestine into the bloodstream.

To overcome these hurdles, scientists combined two approaches to shield insulin from the digestive enzymes and then get it into the blood.

  • They packaged insulin in tiny sacs made of lipids, or fats, called liposomes, which are already used in some treatments. Then, they wrapped the liposomes in layers of protective molecules called polyelectrolytes.

  • To help these “layersomes” get absorbed into the bloodstream, they attached folic acid, a kind of vitamin B that has been shown to help transport liposomes across the intestinal wall into the blood.
About Diabetes

  • Diabetes suppresses the production or use of insulin, which is a hormone that helps blood glucose or blood sugar become absorbed into cells and gives them energy.

  • Type 1 diabetes occurs when the body doesn’t make enough insulin, and type 2 diabetes occurs when the body doesn’t make or use insulin very well, causing glucose to remain in the blood, which can lead to serious problems.

First human artificial heart transplant executed in France

December 24, 2013

An artificial heart that can give patients up to five years of extra life has been successfully implanted for the first time, at Georges Pompidou Hospital in Paris,France. The equipment designed to overcome the worldwide shortage of transplant donors was produce by French Biomedical firm Carmat, a start-up funded by the Dutch-based European Aeronautic Defense and Space Company (EADS).

About Artificial Heart

  • Powered by external, wearable Lithium-ion batteries.

  • Inside the heart, surfaces that come into contact with human blood are made partly from bovine tissue instead of synthetic materials such as plastic that can cause blood clots.

  • Uses a range of “biomaterials”, including bovine tissue, to reduce the likelihood of the body rejecting it.

  • Weighs about 900g (around 2 lb) – nearly three times more than an average healthy human heart. It is expected to cost 140,000 to 180,000 euros in Europe.

  • It mimics heart muscle contractions and contains sensors that adapt the blood flow to the patient’s moves.

  • Intended to replace a real heart for as many as five   years, unlike previous artificial hearts that were created mainly for temporary use.
