tissue-engineered biomaterials have existed approximately 40 years as simple biomimetic structures. replacement of human tissue with new tissue can be accomplished by generating replacements outside of the body or in situ in the body. in each case, the key elements are described as the tissue engineering triad of scaffolds, cells, and signals. scaffolds can be produced synthetically or derived ...

We studied changes in the ultrastructure of brain tissues - medulla oblongata and striatum, as well lung heart experimental parkinsonism caused by action rotenone, which was administered once or for 2 weeks. It has been shown that during development a Parkinson-like state disturbance, mitochondrial endothelial dysfunction is observed not only parts brain, but also other body. Mitochondrial sign...

in order to investigate the microbiological safety of sanitary tissues made of recycled scrap papers in iran, random samples were taken for one year with the cooperation of the iranian standard and industrial research institute (karaj unit), of 44 types of sanitary tissues, two samples of each type including tissues, toilet papers and dippers as well as a control sample and their probable conta...

laser-tissue interaction is of great interest due to its significant application in biomedical optics in both diagnostic and treatment purposes. major aspects of the laser-tissue interaction which has to be considered in biomedical studies are the thermal properties of the tissue and the thermal changes caused by the interaction of light and tissue. in this review paper the effects of light on ...
