Many investigators are interested in finding the new cultural systems that can support the in vitro development of pre-implantation embryos better. Previous studies suggested that growth factors such as epidermal growth factor (EGF) are important in pre-implantation embryo development and implantation process. On the other hand, it is very important to support post thaw development of frozen em...

the incidence of traumatic brain injury (tbi) are annually increasing, developed tissue engineering methods could represent the definite remedies for patients with strongly injured central nervous system and have a great effect in the public healthcare cost. the current clinical treatments in tbi display several limitations. furthermore, several therapies, coming from neural tissue engineering ...

Formal criteria of theoretical equivalence are mathematical mappings between specific sorts objects, notably including those objects used in physics. Proponents formal claim that results involving these have implications extend beyond pure mathematics. For instance, they bear on the project using our best physics as a guide to what world is like, and also deflationary for various debates metaph...

Zebrafish are able to completely regrow their caudal fin-folds after amputation. Following injury, wound healing occurs, followed by the formation of a blastema, which produces cells to replace the lost tissue in the final phase of regenerative outgrowth. Here we show that, surprisingly, the phosphatase and tumor suppressor Pten, an antagonist of phosphoinositide-3-kinase (PI3K) signaling, is r...

The old wishes of people were to regenerate lost tissues of periodontium that this fact is achieved by gen and cell therapy .Periodontal disease is a chronic inflammation around the tooth by microbes that causes destruction of supporting structure of tissue of tooth such as alveolar bone, cementum and periodontal ligament. For treatment of periodontal diseases we can use the biomaterials which ...

The genes encoding the insecticidal crystal proteins (ICPs) of BacIllus thuringiensis are good candidates for protecting walnut plants against insect pests. Ve have estimated the dose response of three important walnut pests (codling moth, navel orangeworm and Indianmeal moth) with two highly purified insecticidal proteins of Bacillus thurJ.nglensis and show that these three insects are highly ...
