Abstract
In this work, we demonstrate controlled drug delivery from low-temperature-sensitive liposomes (LTSLs) mediated by photothermal heating from multibranched gold nanoantennas (MGNs) in triple-negative breast cancer (TNBC) cells in vitro. The unique geometry of MGNs enables the generation of mild hyperthermia (∼42 °C) by converting near-infrared light to heat and effectively delivering doxorubicin (DOX) from the LTSLs in breast cancer cells. We confirmed the cellular uptake of MGNs by using both fluorescence confocal Z-stack imaging and transmission electron microscopy (TEM) imaging. We performed a cellular viability assay and live/dead cell fluorescence imaging of the combined therapeutic effects of MGNs with DOX-loaded LTSLs (DOX-LTSLs) and compared them with free DOX and DOX-loaded non-temperature-sensitive liposomes (DOX-NTSLs). Imaging of fluorescent live/dead cell indicators and MTT assay outcomes both demonstrated significant decreases in cellular viability when cells were treated with the combination therapy. Because of the high phase-transition temperature of NTSLs, no drug delivery was observed from the DOX-NTSLs. Notably, even at a low DOX concentration of 0.5 μg/mL, the combination treatment resulted in a higher (33%) cell death relative to free DOX (17% cell death). The results of our work demonstrate that the synergistic therapeutic effect of photothermal hyperthermia of MGNs with drug delivery from the LTSLs can successfully eradicate aggressive breast cancer cells with higher efficacy than free DOX by providing a controlled light-activated approach and minimizing off-target toxicity.

Abstract
For late-stage cancer, whole-body hyperthermia (WBH) is highly regarded by physicians as a promising alternative to conventional therapies. Although WBH is still under scrutiny due to potential toxicity, its benefits are incomparable, as diversified devices and very promising treatment protocols in this area are advanced into Phase II and III clinical trials. Following the introduction of the WBH principle, this paper comprehensively reviews the state-of-art high-performance WBH devices based on the heat induction mechanisms - radiation, convection and conduction. Through analyzing each category's physical principle and heat-induction property, the advantages and disadvantages of the devices are evaluated. Technical strategies and critical scientific issues are summarized. For future developments, research directions worth pursuing are presented in this article.

Abstract
AIM: To investigate the relationship between the reversing effect of phenylpropanoid glycoside (PPG) on multidrug resistance of colon carcinoma LoVo/Adr cells and apoptosis.
METHODS: LoVo/Adr cells were divided into three groups: non-treatment (negative control) group, PPG treatment group (treated with 40 mg/L PPG) and verapamil treatment (positive control) group (treated with 5 mg/L VP). The effects of PPG on multidrug resistance of LoVo/Adr cells were examined by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay. The effects of PPG on cell apoptosis were detected by flow cytometry. The effects of PPG on the activity of Caspase-3 were evaluated by determining pNA release rate.
RESULTS: PPG could decrease the half maximal inhibitory concentration (IC50) of adriamycin in LoVo cells and reverse their resistance to adriamycin. The reversal index was 9.93. PPG could significantly induce the apoptosis of LoVo cells when compared with the non-treatment group (P < 0.01). The rate of pNA release in the PPG treatment group was significantly higher than that in the non-treatment group (31.75 ± 4.34 pmol/min vs 18.45 ± 2.39 pmol/min, P < 0.01). Caspase-3 inhibitor Z-VAD-FMK could significantly inhibit PPG-induced pNA release (17.69 ± 2.68 pmol/min vs 31.75 ± 4.34 pmol/min, P < 0.01).
CONCLUSION: PPG reverse multidrug resistance of LoVo/Adr cells perhaps through induction of Caspase 3-dependent apoptosis.
