Characteristics of changes in volatile organic compounds and microbial communities during the storage of pickles.

The variations of volatile organic compounds (VOCs) and microbial communities of three pickles during storage at 4°C for one week were analyzed by headspace-gas chromatography-ion mobility spectrometry (HS-GC-IMS), high-throughput sequencing, and Spearman correlation analysis. A total of 50 VOCs were identified from three pickles. During storage, most alcohols, aldehydes, ketones, and esters decreased, while acids increased, and sulfides, alkenes, and phenols were relatively equal.

The regulatory effect of total flavonoids of L. on oxidative stress in type 1 diabetic mice.

In this study, the optimal extraction conditions for the total flavonoids of L. (STF) were optimized by response surface methodology. Evaluation of the antioxidant in vitro of STF, and modulatory effects of glucolipid metabolism, and oxidative stress in mice with type 1 diabetes mellitus (T1DM).

[Pollution Characteristics of Snowmelt Runoff on Different Underlying Surface in Main Urban Area of Harbin].

Snowmelt runoff is the main non-point pollution source of receiving water in the high latitude cities of north China in Spring. In order to control the pollution of surface water body by the snowmelt runoff, the pollution characteristics of 6 kinds of underlying surfaces and 18 sampling points in the main urban area of Harbin were analyzed from late March to early April 2015. Through software SPSS 22.
