Effects of metallic contacts on electron transport through graphene

, 2010
We report on a first-principles study of the conductance through graphene suspended between Al contacts as a function of junction length, width, and orientation. The charge transfer at the leads and into the freestanding section gives rise to an electron-

Retention of differentiated properties in an established dog kidney epithelial cell line (MDCK). [PDF]

, 1979
Madin-Darby canine kidney (MDCK) cells grown in tissue culture have the morphological properties of distal tubular epithelial cells, form tight junctions, and lack several proximal tubular enzyme markers.

Magnetic Fields Effects on the Electronic Conduction Properties of Molecular Ring Structures

, 2011
While mesoscopic conducting loops are sensitive to external magnetic fields, as seen by observations of the Aharonov-Bohm (AB) effect in such structures, the field needed to observe the AB periodicity in small molecular rings is unrealistically large ...

ORGAN SPECIFIC VASCULAR RESPONSE TO FIBROSIS AFFECTS BREAST CANCER METASTATIC ORGANOTROPISM [PDF]

, 2016
The solid tumor microenvironment, pre-metastatic niche, and fibrotic environment are known to have significant biochemical and biomechanical similarities to the fibrotic environment. All have significantly increased levels of factors such as TGFβ, HIF1α,

Rab7a is required to degrade select blood-brain barrier junctional proteins after ischemic stroke

Acta Neuropathologica Communications
The integrity of adherens and tight junctions is critical for blood-brain barrier (BBB) function in the healthy brain. Disassembly of cell junctions due to degradation of adherens and tight junction-associated proteins leads to acute BBB dysfunction ...

Caveolin 1 Regulates the Tight Junctions between Sertoli Cells and Promotes the Integrity of Blood–Testis Barrier in Yak via the FAK/ERK Signaling Pathway

Animals
Yaks, a valuable livestock species endemic to China’s Tibetan plateau, have a low reproductive rate. Cryptorchidism is believed to be one of the leading causes of infertility in male yaks. In this study, we compared the morphology of the normal testis of
