Spinal cord injury results in immediate disruption of neuronal membranes, followed by extensive secondary neurodegenerative processes. A key approach for repairing injured spinal cord is to seal the damaged membranes at an early stage. Here, we show that axonal membranes injured by compression can be effectively repaired using self-assembled monomethoxy poly(ethylene glycol)-poly(d,l-lactic aci...

Ultrafiltration, nanofiltration membranes and feed spacers were hydrophilized with polydopamine and polydopamine-g-poly(ethylene glycol) surface coatings. The fouling propensity of modified and unmodified membranes was evaluated by short-term batch protein and bacterial adhesion tests. The fouling propensity of modified and unmodified membranes and spacers was evaluated by continuous biofouling...

Atom transfer radical polymerization (ATRP) was applied to homo and block copolymerization of vinyl monomers methacrylates, acrylates, and styrene with iron (FeCl2.4H2O) as the transition metal in most cases. As complexing ligand either a commercially available ligand (triphenyl phosphine) (PPh3) or synthetic aliphatic amines were used. As initiators, methyl 2-bromopropionate, ethyl 2-bromoisob...

The availability of age-matched normative data is an essential component of clinical gait analyses. Comparison of normative gait databases is difficult due to the high-dimensionality and temporal nature of the various gait waveforms. The purpose of this study was to provide a method of comparing the sagittal joint angle data between two normative databases. We compared a modern gait database to...

Background: Mc Indoe vaginoplasty is one of the mostly performed surgical interventions in Mullerian agenesis. Case presentations: We present our experience on the use of a new designed vaginal stent that was coated with silicone in two mullerian agenesis cases who had Mc Indoe vaginoplasty. Both full thickness and splitt thickness skin graft were used with the stent. No graft loss or hyperthro...

Multicompartment micelles with tunable compartment solubility have been prepared in alcohols from a metallo-supramolecular poly(p-tetrafluoromethylstyrene)-block-poly(tert-butylacrylate)-block-poly(styrene)-[Ru]-poly(ethylene glycol) tetrablock quaterpolymer.

Nature has designed and optimized materials to possess a range of properties functions. Here, we introduced molecular design strategy impart customizable functionality varying mechanical into gels; mimicking nature’s tunable materials. We demonstrate gel that is not only tough but also exhibits self-healing, easily controllable, the final have broad properties. To develop these materials, first...
