To discriminate R and S Myrrh flavanone glycoside using NMR, the mixture of R and S naringenin 7-O-glycoside was first isolated from Gleditsia sinensis.1H and 13C NMR data of the mixture were recorded with 1H NMR, 13C NMR, 1H-1H COSY, 1H-13C HSQC and 1H-13C HMBC in DMSO-d6 solution.The two diastereomers were then separated with chiral chromatograph
ABSTRACT Introduction and objectives: The PSP (pre-dilation, sizing and post-dilation) score, derived from the GHOST-EU registry, has evaluated the relationship between the implantation technique of bioresorbable scaffolds and the clinical outcomes.The objective was to perform an external validation of the PSP technique and to determine its effect
Specific ecological interactions between insects and microbes have potential in the development of targeted pest monitoring or control techniques for the spotted wing drosophilid, Drosophila suzukii (Matsumura), an exotic invasive pest of soft fruit.To evaluate D.suzukii attraction to yeast species from preferred types of fruit, three yeasts were i
