We review the recent advances in both unipolar and bipolar organic spin valves. We discuss mechanisms that dominate the spin relaxation of injected spin aligned carriers and limit their spin diffusion length. A space charge limited current model with ferromagnetic electrodes is used to describe the bipolar organic spin valve ...

Immunoregulatory mechanisms within periapical lesions (PLs) are as yet unexplored. Considering the crucial role of DCs in controlling the immune response within PLs, the immunomodulatory properties of mesenchymal stem cells (MSCs), and the co-localisation of MSCs and DCs in situ, we wondered whether MSCs from PLs modulate the development and ...

Gold or mercury salts trigger a dramatic IgE response and a CD4 T-cell-dependent nephropathy in Brown-Norway (BN), but not in Lewis (LEW) rats. We previously identified the 1.1-Mb Iresp3 (immunoglobin response QTL3) locus on chromosome 9 that controls these gold salt-triggered immune disorders. In the present work, we investigated the ...

This work creatively uses peroxidase-like ZnS hollow spheres (ZnS HSs) to cooperate with glucose oxidase (GOx) for glucose determinations. This approach is that the ZnS HSs electrocatalytically oxidate the enzymatically generated H2O2 to O2, and then the O2 circularly participates in the previous glucose oxidation by glucose oxidase. Au nanoparticles ...
