Photoactive theranostics including photodynamic therapy (PDT) hace aroused an intensive interest that combines medical diagnostics with treatment under a single irradiation laser. However, the conventional organic PDT agents usually suffer from aggregation caused by quenching effect.

In this research, four heuristic algorithms (HAs), including simulated annealing (SA), improved with a harmony search algorithm (HSA), particle swarm optimization (PSO), and genetic (GA), were used to optimize the luminescent intensity of phosphor. Among HAs, HSA got better phosphors than SA (without using known coded concentration). The PSO gradually results increased generation, GA could find best local shorter time. After further analysis 340 phosphors, we found that final brightness has...
In this research, typical organic/inorganic photothermal therapy (PTT) agents were designed with a combination of upconversion luminescent (UCL) or near-infrared (NIR) II imaging rare-earth nanomaterials for photo-acoustic (PA)/UCL/NIR imaging-guided PTT under NIR laser irradiation. The results show the following: (1) effect mainly comes from absorption and partly UCL light conversion. (2) Visible emission is quenched by coated agent visible absorption, indicating that excitation may play...

SUMMARY A suspected dengue fever outbreak occurred in 2010 at a solitary construction site Shenzhen city, China. To investigate this epidemic, we used serological, molecular biological, and bioinformatics techniques. Of nine serum samples from patients, detected seven positive for virus (DENV) antibodies, eight DENV-1 RNA, three containing live viruses. The isolated virus, SZ1029 strain, was sequenced confirmed as DENV-1, showing the highest E-gene homology to D1/Malaysia/36000/05...
