Protection against DSS-induced colitis in mice through FcεRIα deficiency: the role of altered Lactobacillus.

The role of mast cells (MCs) in ulcerative colitis (UC) development is controversial. FcεRI, the IgE high-affinity receptor, is known to activate MCs. However, its role in UC remains unclear.

and served as key components of fecal microbiota transplantation to alleviate colitis.

Fecal microbiota transplantation (FMT) is a promising therapy for inflammatory bowel disease (IBD) via rectifying gut microbiota. The aim of this study was to identify a mechanism of how specific bacteria-associated immune response contributes to alleviated colitis. Forty donors were divided into high () and low () groups according to the diversity and the abundance of and by 16S rRNA sequencing.

The intestinal colonization of Lactiplantibacillus plantarum AR113 is influenced by its mucins and intestinal environment.

Lactiplantibacillus plantarum is an important member of the probiotic family and colonization of the host intestinal is essential for its continued probiotic function. The mechanism of L. plantarum intestinal colonization has not been elucidated until now, an important reason being that the colonization process is influenced by a number of factors.

Synthesis of boronate-functionalized organic-inorganic hybrid monolithic column for the separation of cis-diol containing compounds at low pH.

In this work, an organic-inorganic hybrid boronate affinity monolithic column was prepared via "one-pot" process using 4-vinylphenylboronic acid as organic monomer and divinylbenzene as cross-linker. The effects of reaction temperature, solvents and composition of organic monomers on the column properties (e.g.

Preparation of a long-alkyl-chain-based hybrid monolithic column with mixed-mode interactions using a "one-pot" process for pressurized capillary electrochromatography.

A simple "one-pot" approach for the preparation of a new vinyl-functionalized organic-inorganic hybrid monolithic column is described. In this improved method, the hydrolyzed alkoxysilanes of tetramethoxysilane and triethoxyvinylsilane were used as precursors for the synthesis of a silica-based monolith, while 1-hexadecene and sodium ethylenesulfonate were used as vinyl functional monomers along with azobisisobutyronitrile as an initiator. The effects of reaction temperature, urea content, and composition of organic monomers on the column properties (e.

Preparation and evaluation of o-phenanthroline immobilized on a hybrid silica monolith modified with ionic liquids for reversed-phase pressurized capillary electrochromatography.

A novel o-phenanthroline-immobilized ionic-liquid-modified hybrid monolith for capillary electrochromatography was synthesized based on chloropropyl-silica, which was prepared by the in situ polymerization of tetramethoxysilane and 3-chloropropyltrimethoxysilane via a sol-gel process. The morphology of the hybrid monolith was characterized by scanning electron microscopy, and relatively stable anodic electroosmotic flow was observed under a broad pH ranged from pH 3.0 to 9.

[Effect of snoring on facial growth in children].

Objective: To evaluate the effect of snoring on facial growth in children and the changes after surgery.

Methods: Observations on facial growth were taken by X-ray 1.5 - 2 years before and after surgery on 40 children snorers aged between 2 - 5 years old, whose tonsils and (or) adenoids were completely removed.
