Abstract: In the present invention, among blood metabolites, amino acids, organic compounds and oxylipins that were statistically significantly differentiated from the control group, were selected from type 2 diabetes patients. Specifically, asparagine, aspartic acid, glutamic acid, cysteine, lysine, citric acid, and uric acid, and 12-oxo ETE, 15-oxo ETE, 9-oxo ODE, and 20-carboxy leukotriene B4, which are oxylipins, were confirmed to have cutoff values of AUC>0.7. In addition, the blood metabolites showed a significant difference between a DME patient group and a non-DME patient group, and thus were confirmed to be usable for accurate diagnosis of DME.

Abstract: A Hydrophilic-Lipophilic Deviation theory-based method is provided to prepare representative degassed oil with equivalent minimum miscible pressure to live oil. The method can reduce the number of trial and error type experiments during the representative degassed oil preparation process by measuring the MMP and EACN for dead and live oil. The representative degassed oil formulation could be easily predicted after determining the required MMP and EACN values. The prepared oil can reflect the key mechanism of multiple contact miscible mechanism in the process of gas flooding more accurately. It allows experiments that are inconvenient to use live oil to consider the mechanism of multiple contact miscibility easily.
