A Multifunctional Low-Temperature Photothermal Nanomedicine for Melanoma Treatment via the Oxidative Stress Pathway Therapy.
Article in International journal of nanomedicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: Melanoma is a highly aggressive and dangerous malignant skin tumor and there is an urgent need to develop effective therapeutic approaches against melanoma. The main objective of this study was to construct a multifunctional nanomedicine (GNR@PEG-Qu) to investigate its therapeutic effect on melanoma from the oxidative stress pathway. Methods: First, the nanomedicine GNR@PEG-Qu was synthesized and characterized, and its photothermal and antioxidant properties were confirmed. In addition, in vivo imaging capabilities were observed. Finally, the tumor inhibitory effects of GNR@PEG-Qu in vivo and in vitro as well as its biosafety were observed. Results: GNR@PEG-Qu shows good photothermal and anti-oxidation properties. Following exposure to 1064 nm laser irradiation in the second near-infrared II (NIR-II) window, GNR@PEG-Qu shows anti-tumor ability through low-temperature photothermal therapy (PTT) adjuvant drug chemotherapy. GNR@PEG-Qu makes full use of the antioxidant capacity of quercetin, reduces ROS levels in melanoma, alleviates oxidative stress state, and achieves "oxidative stress avoidance" at the tumor site. Quercetin can also downregulate the expression of the heat shock protein Hsp70, which will improve the thermal sensitivity of the tumor site and enhance the efficacy of low-temperature PTT. Conclusion: GNR@PEG-Qu nanoagent exhibits synergistic treatment and high tumor inhibition effects, which is a promising strategy developed to achieve oxidative stress avoidance and synergistic therapy of melanoma using quercetin (Qu)-coated gold nanorod (GNR@PEG).
