The present study was designed to further the characterization of age-related changes in the deformability of human erythrocytes. The top (approximately young) and bottom (approximately old) 10% fractions of density-separated red cells from ten normal donors were subjected to graded levels of shear stress in a rheoscope. Measurements were made of steady-state elongation (cells tank treading in ...
Many jurisdictions require cyclists to wear bicycle helmets. The UK is currently not one of these. However, an increasing number of interest groups, including the British Medical Association, want to change the status quo. They argue that mandatory cycle helmet laws will reduce the incidence of head injuries and that this will be both good for cyclists (because they will suffer fewer head injur...
Breaststroke, butterfly, front crawl and back crawl: many of us learnt these swimming styles as kids while splashing around in our local pool. These strokes all involve the swimmer lying on their back or front, much like the way most fish swim. Of course, some people prefer to swim tilted to one side rather than face down even though the side-stroke evokes images of elderly swimmers in bathing ...
During directed cell migration, telling cells to avoid certain areas may be as important as attracting them to others. The recently identified wunen gene is involved in the repulsive guidance of migrating primordial germ cells in Drosophila.
the enhanced dispersion of organophilic layered silicates improves the mechanical properties of polymer/ silicate composites. in this work, a hybrid filler system consisting of cloisite 15a organoclay (oc) and carbon black (cb) was used to improve the properties of the tire tread compounds. the physical and mechanical properties of compounds were assessed by measurement of their cure properties...
