Plasma prefractionation methods for proteomic analysis and perspectives in clinical applications 下载免费PDF全文

Plasma is a rich source of biomarkers with clinical relevance. However, the wide dynamic range of protein concentration hinders the detection of low abundance proteins. Plasma prefractionation methods serve as indispensable tools to reduce plasma complexity, allowing the opportunity to explore tissue‐derived proteins which leak into the circulation. This review summarizes common approaches in plasma prefractionation methods for proteomic analysis and then discusses some considerations in plasma prefractionation for clinical applications, reviewing some examples of its use in clinical situations. 相似文献

The catalytic gasification of biochar was investigated in the presence of a Ni/SiO2 catalyst in a fixed bed reactor with an O2-steam-CO2 gas feed. The effects of operating temperature, catalyst nickel loading and composition of O2-steam-CO2 feed gas on biochar carbon conversion and gas products were investigated. The results indicate that the highest biochar carbon conversion could be obtained at approximately 800 °C, whilst the 10% Ni/SiO2 catalyst was shown to produce the greatest syngas yields. The presence of O2 in the feed gas can result in slightly more CO in the gas product, whilst a higher steam content leads to more H2 in the gas product. The CO2 offered a benefit as an adjusting agent for achieving a desired H2/CO ratio. No evidence of coke deposition on the catalyst was found under any of the tested conditions. 相似文献

The use of an oxygen generator based on pressure swing adsorption technology (PSA) has been investigated as an alternative method for supplying oxygen for onsite ozone production. During the investigation period of 1040 h, the oxygen purity from the PSA process fluctuated within a range of 90.5–93 O2% (v/v). Using the working ratio of 2.8 mol of O2 to 1 m3 of raw water, the PSA process in series with a corona discharge ozone generator yielded an oxidation–reduction potential of ca. 200 mV and a concentration of 22.8 mg/L dissolved oxygen. The average efficiency of the raw water treatment was as follows: 47% chemical oxygen demand removal, 78% biological oxygen demand removal, 36% sulphide removal and 34% colour removal. The operating cost of the PSA O2 generation was reduced 3 times compared with the cost of high‐pressure oxygen cylinders. 相似文献

A combined unit of biomass gasifier and tar steam reformer (CGR) was proposed in this study to achieve simultaneous tar removal and increased hydrogen production. Tar steam reforming calculations based on thermodynamic equilibrium were carried out by using Aspen Plus software. Thermodynamic analysis reveals that when selecting appropriate operating conditions, exothermic heat available from the gasifier could sufficiently supply to the heat-demanding units including feed preheaters, steam generator and reformer. The effects of gasification temperature (Tgs), reforming temperature (Tref) and steam-to-biomass ratio (S:BM) on percentages of tar removal and improvement of H2 production were investigated. It was reported that the CGR system can completely remove tar and increase H2 production (1.6 times) under thermally self-sufficient condition. The increase of H2 production is mainly via the water–gas shift reaction. 相似文献
