Some American researchers have got a new role for the candy floss.  According to study it can help create small and intricate blood vessels. The traditional cotton candies have always been an attraction to children for many years. Researchers hope that the findings help the kids’ choice. The research led by Jason Spector of New York-Presbyterian Hospital and Leon Bellan of Cornell University has found that cotton candies can be used as a template to grow artificial vascular networks inside engineered tissue, needed particularly throughout transplants. For the study, the researchers placed several candies in a non-stick mould, and poured over a polymer-resin mix that set hard after a day. Then they dissolved away the sugar using water and alcohol to leave a solid cube shot all the way through with a network of channels.

New Scientist magazine reports after that the researchers discover that the channels were analogous in dimensions to real networks of capillaries. To illustrate that blood could flow very easily through the material, the research group pumped rat blood with fluorescent labeling through the network. Now, the researchers are working on creating casts using a biodegradable resin mixed with cells of a particular tissue, as well as coating the cast’s channels with blood vessel cells. On the other hand, since the cells grow, the biodegradable resin should slowly disappear to leave an artificial tissue sample with its own blood vessel network. However, many think more research need on this matter.

Worldwide, about 135 million people with vision problems wear contact lenses. And most of them don’t know how to take proper care of contact lenses. But, wearing contact lenses is also including risk, only proper selection and maintenance can help keep difficulties to a minimum.

The long term difficulty from weight-loss surgery deserves more attention as number of U.S. procedures is successful. The McClatchy Newspapers reported on Sunday that, Even as stomach-shrinking, or bariatric, surgery has become a standard of care for those with weight-related health issues, no one is yet sure why some bariatric patients fare better than others, or why some even face disastrous side effects.

To cope with epidemic levels of obesity, about 200,000 weight-loss surgeries are being performed in the United States each year as the providers say. These weight-loss surgeries have been proven effective in helping people who suffered from diabetes, high blood pressure, sleep apnea and other issues.

However, between 30 and 40 percents of patients are suffering problems with the bariatric connections, hernias, infections and pneumonia and noting post-surgery problems send 18 percent of patients back to the hospital, sometimes for costly re-admissions or corrective surgery. William Encinosa, lead author of a federal weight-loss surgery study, told McClatchy newspaper, “Anytime you can cut into the intestine, you have a risk of complications,” and also added, “Clearly there are benefits for people who are morbidly obese, but these patients need to know what they are getting into.”
