Making straps from small movements

چکیده
surface is crisscrossed with picket fences made of immobile transmembrane proteins. Until now, single-particle tracking (SPT) has been too slow to provide a high-resolution view of lipid diffusion. In an impressive technical achievement, the authors developed a SPT technique with 25s resolution, and then used it to follow the diffusion of a nonraft lipid in a cell membrane. The lipid molecule was Transmembrane proteins may block lipid movements.

Slow local movements of collagen fibers by fibroblasts drive the rapid global self-organization of collagen gels
Aclassic model for tissue morphogenesis is the formation of ligament-like straps between explants of fibroblasts placed in collagen gels. The patterns arise from mechanical forces exerted by cells on their substrates (Harris et al., 1981). However, where do such straps come from, and how are slow local movements of cells transduced into dramatic long-distance redistributions of collagen? We emb...
متن کاملEffect of backpack shoulder straps length on cervical posture and upper trapezius pressure pain threshold
[Purpose] This study was performed to investigate the effect of the length of backpack shoulder straps on upper trapezius muscle pain threshold and craniovertebral angle. [Subjects and Methods] There were 25 participants, with ages from 15 to 23 years old. Upper trapezius pain threshold and craniovertebral angle were measured for all subjects without the backpack then re-measured after walking ...
متن کاملShort- and Long-term Effects of Using Shooting Straps on Free Throw Accuracy of Young Female Basketball Players
This study identified the shortand long-term effects of using a shooting strap on the accuracy of free throws performed by U15 female basketball players during training and competition. Thirty six female basketball player volunteers (aged 14.3±0.5 years) from the Lithuanian Schoolchildren Basketball League were randomly assigned to either an experimental or control group. The experimental group...
متن کاملFretting Fatigue Behaviour of Pin-Loaded Thermoset Carbon-Fibre-Reinforced Polymer (CFRP) Straps
This paper focuses on the fretting fatigue behaviour of pin-loaded carbon-fibre-reinforced polymer (CFRP) straps studied as models for rigging systems in sailing yachts, for suspenders of arch bridges and for pendent cables in cranes. Eight straps were subjected to an ultimate tensile strength test. In total, 26 straps were subjected to a fretting fatigue test, of which ten did not fail. An S–N...
متن کاملInfrapatellar Straps Decrease Patellar Tendon Strain at the Site of the Jumper’s Knee Lesion
BACKGROUND The impetus for the use of patellar straps in the treatment of patellar tendinopathy has largely been based on empirical evidence and not on any mechanistic rationale. A computational model suggests that patellar tendinopathy may be a result of high localized tendon strains that occur at smaller patella-patellar tendon angles (PPTAs). HYPOTHESIS Infrapatellar straps will decrease t...
