Cytoskeletal Mechanics: Models and Measurements in Cell by Mohammad R. K. Mofrad, Roger D. Kamm

By Mohammad R. K. Mofrad, Roger D. Kamm

This e-book offers an entire spectrum of perspectives on present techniques to modeling phone mechanics. The authors of this ebook come from the biophysics, bioengineering, and actual chemistry groups and every joins the dialogue with a special viewpoint on organic platforms. therefore, the techniques variety from finite point tools common in continuum mechanics to versions of the cytoskeleton as a cross-linked polymer community to types of glassy fabrics and gels. reviews mirror either the static, prompt nature of the constitution, in addition to its dynamic nature as a result of polymerization and the total array of organic approaches. whereas it really is not likely unmarried unifying process will evolve from this range, it truly is our wish larger appreciation of a number of the views will bring about a hugely coordinated method of exploring the basic difficulties and higher discussions between investigators with differing perspectives.

Free Energy Transduction and Biochemical Cycle Kinetics

This small booklet is a simplified, abbreviated, and up-to-date model of the author's loose strength Transduction in Biology, released in 1977 (Academic Press, New York). the current publication is intended to be a textbook for a category or for self-study. the 1st bankruptcy provides a self-contained and user-friendly dialogue of the rules of unfastened strength transduction in biology.

Signal Crosstalk in Plant Stress Responses

Sign Crosstalk in Plant pressure Responses makes a speciality of present findings on sign crosstalk among abiotic and biotic stresses, together with details on drought, chilly, and salt rigidity and pathogen an infection. Divided into seven chapters on serious subject matters within the box, the booklet is written through a global staff of specialist authors.

Protein and Peptide Folding, Misfolding, and Non-Folding

Sheds new mild on intrinsically disordered proteins and peptides, together with their function in neurodegenerative illnesses With the invention of intrinsically disordered proteins and peptides (IDPs), researchers learned that proteins don't inevitably undertake a good outlined secondary and tertiary constitution so that it will practice organic features.

2002). Methods to measure intracellular rheology by macrorheology, diffusion, and sedimentation The experimental designs to measure cytoplasmic (micro)rheology have to overcome three major challenges: the small size of the cell; the heterogeneous structure of the cell interior; and the active remodeling of the cytoplasm that occurs both constitutively, 19 P1: JZZ 0521846374c02 CUFX003/Kamm 20 0 521 84637 0 June 23, 2006 8:51 P. Janmey and C. Schmidt as part of the resting metabolic state, and directly, in response to the application of forces necessary to perform the rheologic measurement.

Optical traps Optical traps (see Fig. 2-8) use a laser beam focused through a high-numerical aperture microscope objective lens to three-dimensionally trap micron-sized refractile particles, usually silica or latex beads (Ashkin, 1997; Svoboda and Block, 1994). The force acting on the bead at a certain distance from the laser focus is in general very difficult to calculate because (1) a high-NA laser focus is not well approximated by a Gaussian, and (2) a micron-sized refractive particle will substantially affect the light field.

Passive microrheology has been used to probe, on microscopic scales, the material properties of systems ranging from simple polymer solutions to the interior of living cells. Optically detected individual probes The simplest method in terms of instrumentation uses video microscopy to record the Brownian motion of the embedded particles.
