Short-Chain Fatty Acids Promote Intracellular Bactericidal Activity in Head Kidney Macrophages From Turbot ( L.) Hypoxia Inducible Factor-1α.

Short-chain fatty acids (SCFAs) are mainly produced by microbiota through the fermentation of carbohydrates in the intestine. Acetate, propionate, and butyrate are the most abundant SCFA metabolites and have been shown to be important in the maintenance of host health. In this study, head kidney macrophages (HKMs) were isolated and cultured from turbots.

A Modular Strategy for Functional Pressure Sensitive Adhesives.

A modular approach to synthesizing functional pressure sensitive adhesives (PSAs) was introduced, wherein a modifiable acrylic PSA copolymer was synthesized by copolymerizing common PSA monomers with 6 mol % glycidyl methacrylate, allowing for subsequent functional group modification via the pendant epoxide functionality. This postmodification technique has the advantage of allowing the installation of a variety of functional groups relevant to adhesion, without variation of molecular weight. Because comparisons of cohesive and adhesive performance of candidate PSAs can be complicated by molecular weight differences, this strategy simplifies direct comparisons of the effects of functional groups on performance.
