Stent Effective In Keeping Arteries Open

...ne used in this study is made with a biodegradable polymer researchers believe will reduce and minimize long-term inflammation and restenosis. This unique everolimus-coated stent freezes the biological process that leads to the renarrowing of arteries after catheter-based treatments. Not only are the patien...

Reducing The Rate Of Infections

...pecialists. Researchers say they have developed a polymer that, when placed in the intestine, does not disturb the ecosystem of the intestine but just provides a chemical shield. In mice, it was 100-percent effective, however research is still in the process and one day researchers hope that they might be a...

Researchers developed world’s smallest toothbrus

...h brush bristles are usually made of animal hairs, polymer fibres and metal wires. Thesehave problems of corroding, wekening and melting. But the new toothbrush will have no such problems. This unique feature will probably give them an advantage to be motorised as well. The researchers who had designed the ...
