Biodegradable stents: truly biodegradable with good tissue harmony.
A 48-year-old man presented to our hospital with corrosive (sulfuric acid)-induced esophageal and pyloric strictures and a barium study showing narrowing of a long segment in the distal esophagus (●" Fig.1a), reduced capacity of stomach, and antropyloric narrowing (●" Fig.1b). Balloon dilation (Boston Scientific, Natick, Massachusetts, USA) of esophageal and pyloric strictures was done over a p...
متن کاملTo clip or not to clip the breast tumor bed? A retrospective look at the geographic miss index and normal tissue index of 110 patients with breast cancer
OBJECTIVE Planning of breast radiation for patients with breast conserving surgery often relies on clinical markers such as scars. Lately, surgical clips have been used to identify the tumor location. The purpose of this study was to evaluate the geographic miss index (GMI) and the normal tissue index (NTI) for the electron boost in breast cancer treatment plans with and without surgical clips....
متن کاملBiodegradable Polymers for Bone Tissue Engineering
The destruction of bone tissue due to disease (osteonecrosis, tumors, osteoporosis) or inefficient healing posttraumatic injury is a problem affecting the world population. The repair of small defect may be mediated by the osteoblast and osteoclast activity which ensures a balanced control of bone resorption and formation, allowing the bone repair, renewal, and growth. However, when the defect ...
متن کاملBiodegradable synthetic polymers for tissue engineering.
This paper reviews biodegradable synthetic polymers focusing on their potential in tissue engineering applications. The major classes of polymers are briefly discussed with regard to synthesis, properties and biodegradability, and known degradation modes and products are indicated based on studies reported in the literature. A vast majority of biodegradable polymers studied belongs to the polye...
متن کاملBiodegradable polymeric fiber structures in tissue engineering.
Tissue engineering offers a promising new approach to create biological alternatives to repair or restore function of damaged or diseased tissues. To obtain three-dimensional tissue constructs, stem or progenitor cells must be combined with a highly porous three-dimensional scaffold, but many of the structures purposed for tissue engineering cannot meet all the criteria required by an adequate ...
