Finding finer functions for partially characterized proteins by protein-protein interaction networks

Based on high-throughput data, numerous algorithms have been designed to find functions of novel proteins. However, the effectiveness of such algorithms is currently limited by some fundamental factors, including (1) the low a-priori probability of novel proteins participating in a detailed function; (2) the huge false data present in high-throughput datasets; (3) the incomplete data coverage of functional classes; (4) the abundant but heterogeneous negative samples for training the algorithms; and (5) the lack of detailed functional knowledge for training algorithms. Here, for partially characterized proteins, we suggest an approach to finding their finer functions based on protein interaction sub-networks or gene expression patterns, defined in function-specific subspaces. The proposed approach can lessen the above-mentioned problems by properly defining the prediction range and functionally filtering the noisy data, and thus can efficiently find proteins’ novel functions. For thousands of yeast and human proteins partially characterized, it is able to reliably find their finer functions (e.g., the translational functions) with more than 90% precision. The predicted finer functions are highly valuable both for guiding the follow-up wet-lab validation and for providing the necessary data for training algorithms to learn other proteins.     

PVC基活性炭的制备及其吸附性能的研究Ⅰ——PVC沥青的制备及其预氧化

以PVC树脂为原料,采用两个恒温段的程序升温方法加热脱氯制备PVC沥青,并通过空气预氧化法,对所制备的PVC沥青进行了预氧化处理.实验结果表明,PVC树脂在流速为100 mL/min氮气气氛中,以10℃/min速率程序升温至270℃,恒温脱氯150 min后再程序升温至410℃并恒温芳化120 min,可以制备出脱氯率和得率均较高的PVC沥青.该PVC沥青在300℃温度下,采用空气预氧化法预氧化120min,可获得增重率约为11%,氧化交联度较高、耐热性能较好的预氧化PVC沥青.FT-IR光谱分析结果表明,PVC沥青在预氧化的过程中,主要发生了氧化脱氢、脱水、CO2缩聚交联反应,使沥青形成耐热型的氧桥结构,从而达到预氧化目的.
