Influence of Vitamin D3 Supplementation on Infliximab Effectiveness in Chinese Patients With Crohn's Disease: A Retrospective Cohort Study.

It remains uncertain whether vitamin D3 (vitD3) supplementation is beneficial for remission of Crohn's disease (CD). The influence of vitD3 supplementation on Infliximab (IFX) effectiveness was analyzed in Chinese CD patients. In this retrospective cohort study, moderate-to-severe CD patients, who were bio-naïve and prescribed with IFX treatment for at least 54 weeks, were recorded from January 2014 to December 2019.

[Molecular phylogeny of the gayal inferred from the analysis of cytochrome b gene entire sequences].

The gayal (Bos frontalis) is a very rare, semi-wild and semi-domestic bovine species. There still exist remarkable divergences on the gayal's origin and phylogenetic status. The cytochrome b (Cyt b) gene entire sequences (1,140 bp) of 11 gayals were sequenced and analyzed.
