PCBs and tight junction expression [PDF]

Environmental Toxicology and Pharmacology, 2008
Polychlorinated biphenyl (PCB) congeners exhibit a broad range of adverse biological effects including neurotoxicity. The mechanisms by which PCBs cause neurotoxic effects are still not completely understood. The blood-brain barrier (BBB) is a physical and metabolic barrier separating brain microenvironment from the peripheral circulation and is mainly

The microscopic basis for phase-sensitive experiments for determination of the order parameter symmetry in Fe-based superconductors

, 2013
We present a microscopic theory of dc Josephson current, based on the construction of a coherent temperature Green function in the tight-binding approximation, in junctions with multiband superconductors.

The Expression and Localization of ZO-1, Claudin 1, and Claudin 4 in the Pig Epididymis

Journal of Animal Reproduction and Biotechnology, 2019
Tight junctions are constituents of the blood–epididymis barrier that play roles in regulating the unidirectional transcellular transport of ions, water, and solutes to maintain optimal conditions for sperm maturation and storage. Claudin 1 (Cldn1) and 4

Tight-binding study of bilayer graphene Josephson junctions

, 2012
Using highly efficient simulations of the tight-binding Bogoliubov-de Gennes model we solved self-consistently for the pair correlation and the Josephson current in a Superconducting-Bilayer graphene-Superconducting Josephson junction.

Tight junction proteins.

Biochimica et biophysica acta, 1998
A fundamental function of epithelia and endothelia is to separate different compartments within the organism and to regulate the exchange of substances between them. The tight junction (TJ) constitutes the barrier both to the passage of ions and molecules through the paracellular pathway and to the movement of proteins and lipids between the apical and

Band structures of periodic carbon nanotube junctions and their symmetries analyzed by the effective mass approximation

, 1998
The band structures of the periodic nanotube junctions are investigated by the effective mass theory and the tight binding model. The periodic junctions are constructed by introducing pairs of a pentagonal defect and a heptagonal defect periodically in

Collective cell migration: Implications for wound healing and cancer invasion. [PDF]

, 2013
During embryonic morphogenesis, wound repair and cancer invasion, cells often migrate collectively via tight cell-cell junctions, a process named collective migration.

The development and characterization of a human mesothelioma in vitro 3D model to investigate immunotoxin therapy. [PDF]

, 2011
BackgroundTumor microenvironments present significant barriers to penetration by antibodies and immunoconjugates. Tumor microenvironments, however, are difficult to study in vitro.

VE-cadherin and claudin-5: it takes two to tango [PDF]

, 2008
Endothelial barrier function requires the adhesive activity of VE-cadherin and claudin-5, which are key components of adherens and tight endothelial junctions, respectively.

Demonstration of Extracellular Space by Freeze-Drying in the Cerebellar Molecular Layer [PDF]

, 1966
In electron micrographs of the molecular layer of the mouse cerebellum frozen within 30 sec of circulatory arrest and subsequently dried at -79 °C an appreciable extracellular space was found between the axons of the granular cells.
