Cyclic stretching is pivotal to maintenance of the ligaments. However, it is still not clear when ligament fibroblasts switch on expression of genes related to the mechanotransduction pathway in response to cyclic stretching. This in vitro study investigated, using ligament fibroblasts, the time-dependent changes in distribution and gene expression of beta1 integrin, the cytoskeleton, and colla...

to identify the larvicidal activities of silver nanoparticles synthesized with acanthus ilicifolius (a. ilicifolius) leaf extract against the larvae of armigeressubalbatus and aedesaegypti. in vitro larvicidal activities such as lc50 and lc90 were assessed for the a. subalbatus  and ae.aegypti larval species. further, characterization using different techniques such as uv, sem,edax, xrd and fti...

The prevalence of sports injuries in martial arts is high. Most Taekwondo injuries also occur in the lower extremities. The aim of this study is to compare the effect of a period of plyometric exercises, with and without stretching exercises, on knee valgus dynamics, flexibility and functional variables of elite female taekwondo athletes at risk of anterior cruciate ligament injuries.  45 elite...

Davis, D.S., P.E. Ashby, K.L. McCale, J.A. McQuain, and J.M. Wine. The effectiveness of 3 stretching techniques on hamstring flexibility using consistent stretching parameters. J. Strength Cond. Res. 19(1):27–32. 2005.—This study compares the effects of 3 common stretching techniques on the length of the hamstring muscle group during a 4-week training program. Subjects were 19 young adults betw...

State-of-the-art BFT protocols remain far from the maximum theoretical throughput. Based on exhaustive evaluation and monitoring of existing BFT protocols, we highlight few impediments to their scaling. These include the use of IP multicast, the presence of bottlenecks due to asymmetric replica processing, and an unbalanced network bandwidth utilization. To better evaluate the actual impact of ...

infrared spectra of some deuterio analogues of carboxylic acids in heavy water have been investigated and their spectral behavior in carbonyl stretching frequency region have been interpreted in terms of their structural behavior in aqueous solutions. it has been shown that a linear relationship exists between carbonyl stretching frequency of solvated acids at infinite dilution and their pk s .

We give a generalized definition of stretch that simplifies the efficient construction of lowstretch embeddings suitable for graph algorithms. The generalization, based on discounting highly stretched edges by taking their pth power for some 0 < p < 1, is directly related to performances of existing algorithms. This discounting of high-stretch edges allows us to treat many classes of edges with...

background: there have been numerous researches on elastomeric ligatures, but clinical conditions in different stages of treatment are not exactly similar to laboratory conditions. the aim of this in vitro study was to simulate clinical conditions and evaluate the effect of three stretching patterns on the amount of force, tensile strength (ts) and extension to ts of the elastomers during 8 wee...

the effect of a transverse magnetic field on the boundary layer flow and heat transfer of anisothermal stretching cylinder is analyzed. the governing partial differential equations for themagnetohydrodynamic, temperature, and concentration boundary layers are transformed into a setof ordinary differential equations using similarity transformations. the obtained ordinarydifferential equations ar...
