ductance of layer. These dependencies showed that hybridization appears when sheet conductance of layer (σ) exceeds some critical value σcr), the magnitude of which changes in wide range and depends on material and plate orientation. For example, for aforementioned hybrid pair A0 SH0 in potassium niobate σcr = 10−3S. If σ < σcr modes are not coupled, i.e. their dispersion curves do not repulse....

Inflammatory bowel disease (IBD) is characterized by an impaired intestinal barrier function. We aimed to investigate the role of reticulon-4B (RTN-4B/NOGO-B), a structural protein of the endoplasmic reticulum, in intestinal barrier function and IBD. We used immunohistochemistry, confocal microscopy, real-time PCR, and Western blotting to study tissue distribution and expression levels of RTN-4...

PURPOSE To prospectively evaluate whether cardiac gating can improve the reproducibility of intravoxel incoherent motion (IVIM) parameters in the head and neck, we performed IVIM diffusion-weighted imaging (DWI) using 4 b values (4b), 4 b values with cardiac gating (4b gating) and 17 b values (17b). METHODS We performed IVIM DWI twice per person on nine healthy volunteers using 4b, 4b gating ...

An insertion mutant of gtcA, responsible for serotype-specific glycosylation of the cell wall teichoic acid in serotype 4b strains of Listeria monocytogenes, was also resistant to both Listeria genus- and serotype 4b-specific phages. The sugar substituents on teichoic acid appeared essential for the adsorption of phages A500 (serotype 4b specific) and A511 (Listeria genus specific) to serotype ...
