Peptide BG From Bitter Gourd () Improves Adjuvant-Induced Arthritis by Modulating the Necroptosis/Neutrophil Extracellular Traps/Inflammation Axis and the Gut Microbiota.

BG is a novel bioactive peptide derived from bitter gourd (), known for its anti-inflammatory and immunomodulatory properties. In the present study, our objective is to investigate the functional roles and mechanisms of BG in the context of rheumatoid arthritis (RA). A rat model of adjuvant-induced arthritis (AIA) was established by administering complete Freund's adjuvant (CFA).

A phylo-functional core of gut microbiota in healthy young Chinese cohorts across lifestyles, geography and ethnicities.

Structural profiling of healthy human gut microbiota across heterogeneous populations is necessary for benchmarking and characterizing the potential ecosystem services provided by particular gut symbionts for maintaining the health of their hosts. Here we performed a large structural survey of fecal microbiota in 314 healthy young adults, covering 20 rural and urban cohorts from 7 ethnic groups living in 9 provinces throughout China. Canonical analysis of unweighted UniFrac principal coordinates clustered the subjects mainly by their ethnicities/geography and less so by lifestyles.

The effective expression of xylanase gene in Candida utilis by 18S rDNA targeted homologous recombination in pGLR9K.

In order to test whether 18S rDNA can influence positively xylanase gene effective expression in the yeast of Candida utilis, a targeting vector pGLR9K-XA was constructed by adding an interested gene xynA from Streptomyces olivaceoviridis into the vector pGLR9K which is constructed by ourselves. pGLR9K contains the 18S rDNA, GAP promoter and CYH resistance gene sequence, all of which is from C. utilis.

HLA-DPB1, -DRB1, and -DQB1 polymorphism defined in Ewenki ethnic minority of China Inner Mongolia Autonomous Region.

In the present study, DNA typing for human leucocyte antigen (HLA)-DPB1, -DRB1, and -DQB1 was performed using polymerase chain reaction-sequence-based-typing (PCR-SBT) method on 94 randomly selected, healthy, unrelated individuals from the Ewenki ethnic population in Inner Mongolia Autonomous Region of China. A total of 64 alleles: 25 in DRB1, 19 in DQB1 and 20 in DPB1, were found. Among the 25 detected DRB1 alleles, DRB1*090102, DRB1*030101, DRB1*040101, DRB1*070101, and DRB1*120101/1206 were commonly observed, with frequencies of 16.
