A metal to insulator transition in integer or half integer charge systems can be regarded as crystallization of charges. The insulating state tends to have a glassy nature when randomness or geometrical frustration exists. We report that the charge...

An isoquinoline-based ligand, N,N,N',N'-tetrakis(1-isoquinolylmethyl)-2-hydroxy-1,3-propanediamine (1-isoHTQHPN), exhibits a fluorescence increase at 475 nm upon addition of 1 equiv. of Zn(2+) (IZn/I0 = 12, ϕZn = 0.023). This fluorescence enhancement turns and then decreases sharply after the addition of more than...

The fluorescence kinetics of a new photosensitizer for photodynamic therapy, di-l-arginine protoporphyrinate (PP(Arg)2), was studied in the skin of healthy mice. Furthermore, induction of necrosis in WiDr human colon adenocarcinoma xenografts in athymic nude mice was studied after photodynamic...

p62/SQSTM1 levels predicts radiotherapy resistance in hypopharyngeal carcinomas.

American journal of cancer research

Am J Cancer Res. 2017 Apr 01;7(4):881-891. eCollection 2017.

Hypopharyngeal carcinoma is one of the worst prognostic malignancies among head and neck carcinomas. Therefore, a good biomarker should be identified to predict the best therapeutic option before starting the treatment. In cell models, p62/SQSTM1 levels affected the Nrf2-Keap1...

A fluorescent X-ray interference method can effectively measure nanometer-level conformational changes for non-crystallized molecules and proteins in aqueous conditions. The time-resolved technique can be used to obtain information about the dynamics of molecules and proteins. Instrumentation for time-resolved fluorescent...
