In this study we investigated the effects of materials prepared with electrical poling on neurite outgrowth in vitro and nerve regeneration vivo. Neuro-2a cells were seeded poled unpoled poly(lactic-co-glycolic) (PLGA) films observed at time periods 24, 48 72 h post-seeding. The percentage neurites per cell quantified using light microscopy. At post-seeding, both number significantly increased compared to those films. An established rat sciatic model was used for vivo studies assess PLGA...

Justice-involved individuals with alcohol and drug use problems reoffend at higher rates than their nonusing counterparts, serving as an important vector to recidivism. At the daily level, exposure stressors may exacerbate problematic use; individual prior treatment experiences mitigate substance adapt learn new coping mechanisms. We conducted a diary study using Interactive Voice Response technology over 14 consecutive days 117 men on probation or parole participating in community-based...

Abstract Mechanical and physicochemical outcomes were used to predict the resorption rate of polylactide‐based internal fixation devices with without incorporation an osteoconductive buffer. Devices degraded in vitro for 1 year. Addition buffer a resorbable polymer device controlled acid generation resulting from hydrolysis. The pH physiological remained neutral when it was exposed buffered screw, whereas decreased approximately 3.0 polylactide device. Neutralizaton acids generated during...

A new type of in situ, remotely monitored magnetism-based sensor is presented that comprised an array magnetically soft, magnetostatically-coupled ferromagnetic thin-film elements or particles combined with a chemically responsive material swells shrinks response to the analyte interest. As changes size distance between changes, altering inter-element magnetostatic coupling. This turn coercive force sensor, amplitude voltage spikes detected nearby pick-up coils upon magnetization reversal...

Morpholine has been chosen for the study of TiO2 photocatalytic degradation saturated heterocyclic compounds in water because it is found a number industrial effluents. Its disappearance rate was observed to be much greater with, than without, UV spectral range. Furthermore, comparison with variety aromatic pollutants shown high degradability morpholine, despite its low coverage surface. Combined GC–MS and HPLC–photodiode-array analyses intermediates have formation hydroxy oxo derivatives...

A new type of continuously operating, in-situ, remotely monitored sensor is presented. The comprised a thin film array magnetostatically coupled, magnetically soft ferromagnetic structures, adhered to or encased within polymer layer. made so that it swells shrinks in response the chemical analyte interest, which this case pH. As shrinks, magnetostatic coupling between magnetic elements changes, resulting changes switching characteristics sensor. Placed sinusoidal field magnetization vector...

OBJECTIVE: This study explored medication-assisted treatment (MAT), the combined use of medication and psychosocial treatment, as a strategy for reducing violent outcomes in community-based offenders. The primary aims were to: 1) examine associations between participant characteristics adherence; 2) adherence substance use; 3) outcomes; 4) determine whether may be attributable to reductions use. METHOD: Baseline interviews completed with 129 male offenders prior their first MAT appointment....

Abstract A porous, resorbable polymer composite based on poly(propylene glycol‐co‐fumaric acid) (PPF) was mechanically evaluated in vitro for use as a bone graft substitute and fracture fixative. The test material created dynamic system capable of initially providing mechanical integrity to bony voids degradative mechanism ingrowth by native bone. unsaturated polymer, PPF, crosslinked the presence effervescent agents yield porous microstructure upon curing. An degradation study first...

In this article, we present an experimental study of the overwrite degradation in high speed recording. Recorded hard and easy transitions were directly characterized correlated to medium speed, write current waveform media properties. It has been found that, when becomes greater than bubble growth transition will be recorded field gradient is poor, which results not only large shift, but also broadening. Slow rise time causes further due effective slowing down speed. Write overshoot can...
