Tailored Covalent Organic Frameworks Enable the Encapsulation of Living Cells to Produce Rare Ginsenoside

Advanced Science, EarlyView.
This work reports the in situ fabrication of Escherichia coli@covalent organic frameworks (E. coli@COFs) in phosphate‐buffered saline. The COFs form an exoskeleton on E. coli, protecting intracellular β‐glucosidase (Ssbgl) while enhancing mass transfer.

Oral Nanomicelle‐Mediated Sequential Butyrate Production in the Intestine for Ulcerative Colitis and Immunosuppression Treatment

Advanced Science, EarlyView.
After oral administration, inodorous GLU‐BA self‐assembles into nanomicelles in aqueous environments to resist premature gastric adsorption. Upon reaching the intestine, endogenous esterases rapidly cleave the built‐in ester bonds in these nanomicelles to release BA and GLU, with GLU further metabolized by gut microbiota to gradually generate BA ...

Cellular basis for blade splitting in bull kelp, Nereocystis luetkeana

American Journal of Botany, EarlyView.
Abstract Premise Blade splitting in bull kelp, Nereocystis luetkeana is central to thallus development and function, yet the cellular basis of this process remains poorly understood. Two historical models proposed contrasting mechanisms: One attributes blade separation primarily to programmed cell death, whereas the other suggests mechanical tearing ...

The potency of native postbiotics and paraprobiotics in modulating inflammation by affecting the gut–kidney axis

Animal Models and Experimental Medicine, EarlyView.
Native postbiotics and paraprobiotics derived from Lactobacillus and Bifidobacterium strains were administered to dextran sulfate sodium–treated C57BL/6 mice to evaluate their impact on kidney inflammation via the gut–kidney axis. Histological analysis and quantitative polymerase chain reaction of autophagy‐related genes (atg5, atg7, atg12, atg13 ...
