Functional properties of the diaphragm are mediated by muscle structure. Modeling of force transmission necessitates a precise knowledge of muscle fiber architecture. Because the diaphragm experiences loads both along and transverse to the long axes of its muscle fibers in vivo, the mechanism of force transmission may be more complex than in other skeletal muscles that are loaded uniaxially alo...

Expanded poly(tetrafluoroethylene) fibers were surface modified using an ultraviolet-activated mercury/ammonia reaction to yield amine-functional groups for the coupling of laminin-derived cell adhesive peptides CYIGSR, CDPGYIGSR, CIKVAV, and CQAASIKVAV. Surface elemental composition, determined by X-ray photoelectron spectroscopy, and radiolabeling data indicated that the amount of peptide int...

This study investigates soft composite sheets that undergo significant deformations. The fiber reinforcement in these systems not only increases the stiffness of sheets like a traditional composite, but also controls the relationships between strains in orthogonal planar directions. Such an ability is useful in controlling the deformation of soft robots, and also enhancing the output of soft ac...

Metanx is a product containing L-methylfolate, pyridoxal 5'-phosphate, and methylcobalamin for management of endothelial dysfunction. Metanx ingredients counteract endothelial nitric oxide synthase uncoupling and oxidative stress in vascular endothelium and peripheral nerve. This study evaluates Metanx on diabetic peripheral neuropathy in ZDF rats, a model of type 2 diabetes. Metanx was adminis...

an experiment was carried out to develop and evaluate a semi-purified diet suitable for fiber related studies without negative impacts on performance, serum biochemistry and intestinal morphology of growing japanese quails. total of 144 japanese quail chicks were used in a factorial arrangement using completely randomized design with 6 treatments, 4 replicates of 6 quails in each replicate. the...

PURPOSE To investigate the influence of intersubject variation in ocular parameters on the mapping of retinal locations to the retinal nerve fiber layer and optic nerve head. METHODS One hundred retinal nerve fiber layer (RNFL) bundle photographs from 100 subjects were optimized digitally and single RNFL bundles manually traced back to the ONH where their entry point was noted. A 24-2 visual ...

The input impedance of muscle fibers of the crab was determined with microelectrodes over the frequency range 1 cps to 10 kc/sec. Care was taken to analyze, reduce, and correct for capacitive artifact. One dimensional cable theory was used to determine the properties of the equivalent circuit of the membrane admittance, and the errors introduced by the neglect of the three dimensional spread of...

Irregularities are inherent to virtually all fibers, including the conventional textile fibers, the high-performance brittle fibers and newly developed nano-fibers. These irregularities can fall into two main categories: dimensional or geometrical irregularity (external) and structural irregularity (internal). For natural fibers such as wool, diameter variation along fiber length is atypical ex...

The orientation of unidirectional carbon fibers (UDCFs) in a manufacturing process is critical to the mechanical properties fiber reinforced plastics (CFRPs). This study presents method monitor UDCFs on mold using electrical resistance during CFRP process. An equivalent model for was proposed develop an situ sensor mold. investigated terms its orthotropic properties. technique can have strong i...

The focus of this work was to investigate the cellulose acetate (CA)–viscose (CV) interface in an all-cellulosic compound and evaluate feasibility hydrophobic CA-coatings on viscose fibers. Mechanical strengths foil-CA compounds were investigated by recoding stress-to-strain curves. For equivalent strain, composites generate higher stress than pure CA samples. coating CV fibers, fibers pretreat...
