Homogenization for the multiple scale analysis of musculoskeletal mineralized tissues
Using multiscale models and homogenization methods the elastic properties of two important musculoskeletal mineralized tissues, the mineralized turkey leg tendon (in short mineralized tendon) and the osteon, are modeled and simulated at different length scales. Our first aim is to find homogenization methods which predict the apparent elastic properties of the investigated tissues numerical acc...
متن کاملTransplantation and Potential Immortality of Mammalian Tissues
1. Serial transplantation of tumors made it possible in 1901 and following years to draw the conclusion that various mammalian tissues have potential immortality. Serial transplantations of normal tissues did not succeed at first, because the homoioreaction on the part of the lymphocytes and connective tissue of the host injures the transplant. 2. In continuation of these experiments we found t...
متن کاملThe Potential of Water in Mammalian Tissues
Melting point depression was used as an index of the water potential of rat tissues and serum. Organs removed from anesthetized rats were immediately frozen in liquid nitrogen and ground with mortar and pestle. Aliquots of the resulting frozen powder were suspended in chilled liquid silicone. While the suspension was vigorously stirred and warmed at a constant rate, the temperature of the melti...
متن کاملTiming of circadian genes in mammalian tissues
Circadian clocks are endogenous oscillators driving daily rhythms in physiology. The cell-autonomous clock is governed by an interlocked network of transcriptional feedback loops. Hundreds of clock-controlled genes (CCGs) regulate tissue specific functions. Transcriptome studies reveal that different organs (e.g. liver, heart, adrenal gland) feature substantially varying sets of CCGs with diffe...
متن کاملIsolation of deoxyribonucleic acid from mammalian tissues.
1. DNA has been isolated from different mammalian tissues. The DNA preparations were free from RNA, protein and polysaccharides and have a similar range of sedimentation coefficients (approx. 24s). 2. Protein was removed by a two-stage extraction with a phenol-cresol mixture by using a detergent with 4-aminosalicylate in the first stage and sodium chloride in the second. 3. Polysaccharides rema...
