Effects of intestinal Desulfovibrio bacteria on host health and its potential regulatory strategies: A review.

Increasing studies have focused on the relationship between Desulfovibrio bacteria (DSV) and host health in recent years. However, little is known about the mechanisms by which DSV affects host health and the strategies to accurately regulate DSV numbers. This review mainly presents the relationship between DSV and host health, potential modulatory strategies, and the potential mechanisms affecting host health.

[Thoughts on Construction of Information System of Medical Device Variety Archives].

Objective: Thinking on the construction of the medical device type archives information system.

Methods: This paper introduces the concept and significance of medical device variety archives, and puts forward the overall construction idea and system framework of medical device variety archives by analyzing its construction difficulties.

Results: Considering the long-term nature and complexity of the construction of medical device variety archives, the system can be constructed in accordance with the three steps of system building, platform building and data management, and the overall technical architecture can be designed from the eight aspects of user layer, business application layer, application support layer, data resource layer, infrastructure layer, security, standards and operation and maintenance management.

Modification of chitosan grafted with collagen peptide by enzyme crosslinking.

Free radicals are closely related to the occurrence and development of aging, cancer and inflammation. In this paper, the microbial transglutaminase (MTGase) was used as a catalyst to graft the collagen peptide (COP) molecules on the amino group of carboxymethyl chitosan sulfate (CMCS) to improve the antioxidant effects. FT-IR and NMR spectroscopy were used to confirm the successful grafting of COP to CMCS.

Different B-type methionine sulfoxide reductases in Chlamydomonas may protect the alga against high-light, sulfur-depletion, or oxidative stress.

The genome of unicellular green alga Chlamydomonas reinhardtii contains four genes encoding B-type methionine sulfoxide reductases, MSRB1.1, MSRB1.2, MSRB2.
