Squamous-cell carcinomas of the lung (SQCLCs) are defined by unique clinicopathological and molecular characteristics that have evolved substantially over time. Historically, these neoplasms were the most common subtype of non-small-cell lung cancers and were regarded as central tumours with high molecular complexity without targetable genetic abnormalities. Today, the incidence of ...

During efforts to stabilize metal oxide bound chromophores for photoelectrochemical applications, a novel, photochemical reaction has been discovered. In the reaction, the bis-phosphonate functional groups C(PO3H2)2(OH) in the metal complex [Ru(bpy)2(4,4'-(C(OH)(PO3H2)2bpy)]2+ are converted into COOH and PO43-. The reaction occurs by sensitized formation of 1O2 by the lowest MLCT excited ...

MicroRNAs (miRNAs) are small non-coding, endogenous, single-stranded RNAs. MiRNAs have been implicated in different areas such as the immune response, neural development, DNA repair, apoptosis, oxidative stress response and cancer. However, while the majority of miRNAs are found intracellularly, a significant number of miRNAs have been observed outside of cells, ...

Wear debris-induced osteolysis in periprosthetic tissue with aseptic loosening is a serious problem after total joint arthroplasty. Matrix metalloproteinase-9 (MMP-9) is expressed in osteoclast cells that surround loosening peri-implant tissue, but the molecular mechanism of MMP-9 action in wear debris-induced osteolysis remains ambiguous. We used a murine osteolysis model to ...

The confinement of light within nanometer-scale regions may result in the significant enhancement of light-matter interactions. However, light confinement to nanometers is hindered by the diffraction limit of a dielectric material. For a dielectric cavity, if the material loss is negligible, reducing the cavity size usually causes a significantly increase ...
