Deformation of a red blood cell (RBC) in a high-shear flow was investigated. The RBC was modeled as a closed shell membrane consisting of spring networks in the framework of the energy minimum concept. The simulation of RBC in a parallel shear flow showed deformation parameters of RBC were well agreed with experimental results. The simulation of RBC behavior in various flow fields demonstrated that...
The Human Genome is essentially complete, and yet the impact on how we understand physiological processes such as cellular force transduction has been minimal in part because of our inability to work from known sequence to structure, i.e. the Foldome. In order to specifically identify cytoskeletal proteins that change conformation or assembly in stressed versus static cells, in situ labeling of sterically-shielded...
In all eukaryotes, cytokinesis is a big deformation process that a mother cell is divided to two daughter cells. It is involved in many mechanical actions, such as active contraction of microfilament, viscous flow of cytoplasm and big deformation of cortical membrane. In order to attain a better understanding of the cytokinesis process and corroborate a mechanical mechanism, various theoretical models...
A Fourier transform technique has been used to enhance the genome periodicities when analyzing the distributions of independent nucleotides and dinucleotides. These periodicities are varying from 2 to 500 bp. In this paper we focus on the 3 and 10.5 periodicities. The 3-base periodicity is characteristic for the protein-coding sequences only. The source of the approximately 10.5-base sequence period...
Summary form only given. Platelets adhesion occurs at focal adhesions (FA), where cell-membrane receptors bind specifically to substrate proteins and couple to each other and to the cytoskeleton via various cellular proteins. Some of the reactions that follow the ligand-receptor binding at the FA may affect mechanical determinants of the cell-substrate attachment. The resulting molecular structure...
