Polymer dynamics is the essence of polymer physics. Understanding polymers from the perspective of polymer dynamics is crucial to rationally design and fabricate novel polymeric systems. Poly(propylene fumarate) (PPF) and poly(propylene fumarate)-copolycaprolactone (PPF-co-PCL) (Fig. 1) are two unsaturated linear polyesters that can be crosslinked through its fumarate double bonds. By varying t...

Management of osteoporotic fracture is challenging. In most clinical settings, skeletal regenerations are biologically optimized, but still many patients continue to experience delayed or impaired healing. Methods to enhance these healing processes, are needed to decrease patient’s agony, so that they can return to their work and regain their socioeconomic status in the community. Till this tim...

With the glutathione system that leads to rapid regeneration of reduced lysozyme (Saxena, V. P., and Wetlaufer, D. B. (1971) Biochemistry 9, 5015), reduced pancreatic ribonuclease (RNase) regenerated activity in high yield (greater than 90%) but at a considerably lower rate (t1/2 approximately 75 min). Systematic examination of the effects upon regeneration of the concentrations and ratios of r...

We derive properties of the rate function in Varadhan’s (annealed) large deviation principle for multi-dimensional, ballistic random walk in random environment, in a certain neighborhood of the zero set of the rate function. Our approach relates the LDP to that of regeneration times and distances. The analysis of the latter is possible due to the i.i.d. structure of regenerations.

Osteopetrosis (OP) comprehends a rare group of conditions, presenting on radiographs increased bone density, deriving from irregularities in osteoclast differentiation or function. In the autosomal dominant osteopetrosis (ADO), some patients stay asymptomatic for some time, or only develop mild symptoms. The dental surgeon is often the first to presuppose the disease during routine imaging exam...

People suffering from pain due to osteoarthritic or rheumatoidal changes in the joints are still waiting for a better treatment. Although some studies have achieved success in repairing small cartilage defects, there is no widely accepted method for complete repair of osteochondral defects. Also joint replacements have not yet succeeded in replacing of natural cartilage without complications. T...

the evaluation of the edge effects of forest roads on ecosystem is very useful to understand changes from forest road. with this regard, in this research the effect of main forest road construction on regeneration and biodiversity of established trees in edge of forest road was investigated at 35 m distance into forest area. an existing 10 years old road segment, with same physiographic propert...
