Air Pollution Is Associated with Poor Cognitive Function in Taiwanese Adults.

The issue of air pollution is gaining increasing attention worldwide, and mounting evidence has shown an association between air pollution and cognitive decline. The aim of this study was to investigate the relationships between air pollutants and cognitive impairment using the Mini-Mental State Exam (MMSE) and its sub-domains. In this study, we used data from the Taiwan Biobank combined with detailed daily data on air pollution.

UniQua: a universal signal processor for MS-based qualitative and quantitative proteomics applications.

Recent developments in high resolution mass spectrometry (HR-MS) technology have ushered proteomics into a new era. However, the importance of using a common, open data platform for signal processing of HR-MS spectra has not been sufficiently addressed. In this study, a MS signal processor was developed to facilitate data integration from different instruments and different proteomics approaches into a unified platform without compromising protein identification and quantitation performance.

Diet behavior and low hemoglobin level after laparoscopic mini-gastric bypass surgery.

Background/aims: Nutrition problems caused by laparoscopic mini-gastric bypass surgery (LMGB) include lack of iron, calcium and poor nutrition. Iron deficiency anemia is the common. The purpose of this study was to investigate why our patients' hemoglobin level was at a low value after surgery and the relationship between diet frequency, diet behavior, and low hemoglobin level.

Discovery of novel bladder cancer biomarkers by comparative urine proteomics using iTRAQ technology.

A urine sample preparation workflow for the iTRAQ (isobaric tag for relative and absolute quantitation) technique was established. The reproducibility of this platform was evaluated and applied to discover proteins with differential levels between pooled urine samples from nontumor controls and three bladder cancer patient subgroups with different grades/stages (a total of 14 controls and 23 cancer cases in two multiplex iTRAQ runs). Combining the results of two independent clinical sample sets, a total of 638 urine proteins were identified.
