[Effects of multifunctional plant rhizosphere promoting bacteria on maize growth in black soil areas in Northeast China].

The application of microbial fertilizer plays an important role in improving soil restoration and fertilizer utilization. The effects of microbial fertilizer are greatly affected by crop genotypes and ecological conditions. Little is known about the effects of microbial fertilizers on maize production in Northeast China.

Multiple Comparisons of Glucokinase Activation Mechanisms of Five Mulberry Bioactive Ingredients in Hepatocyte.

Glucokinase (GK) activity, which is rapidly regulated by glucokinase regulatory protein (GKRP) in the liver, is crucial for blood glucose homeostasis. In this paper, the GK activation mechanisms of 1-deoxynojrimycin (DNJ), resveratrol (RES), oxyresveratrol (OXY), cyanidin-3-glucoside (C3G), and cyanidin-3-rutinoside (C3R) were compared. The results revealed that DNJ, RES, C3G, and C3R could differently improve glucose consumption and enhance intracellular GK activities.

Four flavonoid compounds from Phyllostachys edulis leaf extract retard the digestion of starch and its working mechanisms.

Bamboo leaf extract as a food additive has been used for preventing the oxidation of food. In the present study, we investigated the influence of Phyllostachys edulis leaf extract on starch digestion. Orientin, isoorientin, vitexin, and isovitexin were determined as its α-amylase inhibitory constituents.

Optimal waist circumference cut-off values for identifying metabolic risk factors in middle-aged and elderly subjects in Shandong Province of China.

Objective: To study the optimal waist circumference (WC) cut-off values for identifying metabolic risk factors in middle-aged and elderly subjects in Shandong Province of China.

Methods: A total of 2,873 men and 5,559 women were included in this cross-sectional study. Metabolic syndrome (MetS) was diagnosed according to the definition of Chinese Diabetes Society in 2004.

[Advances of research on demethylation therapy for hematologic malignancies].

DNA methylation is an important and reversible epigenetic modification which regulates genomic stability. Methylation is essential for mammalian development. Generally, gene expression level and DNA methylation are negative correlation.
