PEDOT/PVC-modified amperometric carbon electrodes for acetylcholine detection.

We present here new amperometric electrodes for the selective and quantitative detection of acetylcholine. The detection was achieved based on the electrodeposition of a carbon electrode with poly(3,4-ethylenedioxythiophene) (PEDOT) followed by the drop-casting of an ionophore-doped poly(vinyl) chloride (PVC) membrane. This work paves the way for future applied research to study neurological disorders.

A predictive analysis of CO emissions, environmental policy stringency, and economic growth in China.

This study takes environmental policy stringency and economic activity as the controlling variables and forecasts the CO emissions in China up to 2022. In doing so, an application of corrected grey model with convolution is used over the annual time series data between 1990 and 2012. The simulation results show that (1) between 2012 and 2022, CO emissions in China is expected to increase at an average rate of 17.

Nonsurgical management of oropharyngeal, laryngeal, and hypopharyngeal cancer: the Fox Chase Cancer Center experience.

Background: Oropharyngeal, laryngeal, and hypopharyngeal cancer treatment has changed at our institution, but survival outcomes have not been evaluated.

Methods: We approached the evaluation by a retrospective single-institution cohort study.

Results: Review of 180 patient records from 1993 to 2004 revealed that the number of patients with oropharyngeal cancer treated nearly doubled, whereas the number of patients with laryngeal and hypopharyngeal cancers declined (p = .
