Microbiota and maintenance of skin barrier function
Science, 2022Description Human skin forms a protective barrier against the external environment and is our first line of defense against toxic, solar, and pathogenic insults. Our skin also defines our outward appearance, protects our internal tissues and organs, acts

IEEE Control Systems Letters, 2021
This letter considers the problem of obstacle avoidance for multiple robotic agents moving in an environment with obstacles. A decentralized supervisory controller is synthesized based on control barrier functions (CBF) that guarantees obstacle avoidance

Current Opinion in Clinical Nutrition and Metabolic Care, 2002
Intestinal barrier function regulates transport and host defense mechanisms at the mucosal interface with the outside world. Transcellular and paracellular fluxes are tightly controlled by membrane pumps, ion channels and tight junctions, adapting permeability to physiological needs.

High-Throughput Screen Identifies Host and Microbiota Regulators of Intestinal Barrier Function.
Gastroenterology, 2020BACKGROUND & AIMS The intestinal barrier protects intestinal cells from microbes and antigens in the lumen-breaches can alter the composition of the intestinal microbiota, the enteric immune system, and metabolism.

American Journal of Physiology-Gastrointestinal and Liver Physiology, 1981
The ability of an epithelium to prevent permeation of noxious agents has not been well studied except in the gastrointestinal tract where exclusion of H+ has clinical significance. This article reviews the permeation routes across epithelia both as elucidated in the extensive electrophysiological work done in recent years and as demonstrated in ...

Do ‘Functional Barriers’ Function?
Packaging Technology and Science, 1996The direct recycling of plastics (food grade plastic to food grade plastic) obviously gives rise to possible health hazards. Contaminants, picked up by the material during first usage, may migrate into food during second use. ‘Functional barrier’ layers have been used for a long time (e.g.
