Social representations in later medieval culture have attracted little attention amongst psychologists, pre-dating the development of the so-called 'public sphere' in the eighteenth century. In addition, the association of pre-modern societies with 'traditional' modes of communication in social psychology places implicit limits on areas that may be studied through the ...

Oral lichen planus (OLP) is generally accepted to be a T cell-mediated chronic inflammatory disease with an unclear pathogenesis. There have been numerous studies on the proliferation and apoptosis of T cells in situ. In contrast, research on the proliferation and apoptosis of peripheral blood mononuclear cells (PBMCs) in patients ...

Organometallic hexahapto (η(6) )-chromium metal complexation of single-layer graphene, which involves constructive rehybridization of the graphene π-system with the vacant chromium d(π) orbital, leads to field effect devices which retain a high degree of the mobility with enhanced on-off ratio. This η(6) mode of bonding is quite distinct from the ...

A unique procedure is developed to capture carbon nanotubes into closed virus-like protein cages with a controllable shell. The cross-linked shell varies in thickness within ≈10(0) -10(2) nm, and can be entirely removed by enzyme degradation. The cytotoxicity is entirely suppressed, but can be promoted again by enzymes and near-infrared ...

Skin collagen decreases in protein-malnourished states. Amino acids regulate protein metabolism, glutamine stimulates collagen synthesis through the conversion process to proline and provides 75 % of the intracellular free proline in fibroblasts. However, the impact of these amino acids on collagen synthesis under malnutrition has not been examined. We investigated the ...

A novel porous Au@MIL-100(Fe) core-shell nanocatalyst with controllable MIL-100(Fe) shell thickness has been fabricated by using a versatile step-by-step fashion. Catalytic studies show that the Au@MIL-100(Fe) nanocatalyst exhibits much higher catalytic activity than the pure Au nanoparticles, suggesting that the MIL-100(Fe) shell enhances the catalytic activity via a synergistic effect.

The metal-organic framework, MFU-4, possessing small cavities and apertures, is exploited for quantum sieving of hydrogen isotopes. Quantum mechanically, a molecule confined in a small cavity shows an increase in effective size depending on the particle mass, which leads to a faster deuterium adsorption from a H(2) /D(2) isotope mixture.
