Gut microbiota, intestinal permeability, and systemic inflammation: a narrative review
Internal and Emergency Medicine, 2023 The intestine is the largest interface between the internal body and the external environment. The intestinal barrier is a dynamic system influenced by the composition of the intestinal microbiome and the activity of intercellular connections, regulated ...

Paracellular permeability and tight junction regulation in gut health and disease
Nature reviews: Gastroenterology & hepatology, 2023 Epithelial tight junctions define the paracellular permeability of the intestinal barrier. Molecules can cross the tight junctions via two distinct size-selective and charge-selective paracellular pathways: the pore pathway and the leak pathway.

Loading rate dependence of permeability evolution in porous aeolian sandstones [PDF]
, 2004 Mechanical properties of rocks are characterized by their notable dependence on the applied deformation rate. However, little is known about the strain rate dependence of fluid flow properties since most laboratory tests are conducted using a single ...

Dietary calcium decreases but short-chain fructo-oligosaccharides increase colonic permeability in rats [PDF]
, 2010 An increased intestinal permeability is associated with several diseases. Nutrition can influence gut permeability. Previously, we showed that dietary Ca decreases whereas dietary short-chain fructo-oligosaccharides (scFOS) increase intestinal ...

Permeability evolution during progressive development of deformation bands in porous sandstones [PDF]
, 2003 Triaxial deformation experiments were carried out on large (0.1 m) diameter cores of a porous sandstone in order to investigate the evolution of bulk sample permeability as a function of axial strain and effective confining pressure. The log permeability

Decision trees to characterise the roles of permeability and solubility on the prediction of oral absorption. [PDF]
, 2015 Oral absorption depends on many physiological, physiochemical and formulation factors. Two important properties that govern oral absorption are in vitro permeability and solubility, which are commonly used as indicators of human intestinal absorption ...
