The mangrove ecosystem is a unique and important component of coastal ecosystems. However, microplastics, as a new type of environmental pollutant, enter the mangrove system through various pathways and have become a serious challenge for mangroves. This article analyzes the impact of microplastics on the mangrove ecosystem, including the distribution characteristics of microplastics in the mangrove ecosystem, the effects of microplastics on the mangrove ecosystem, the influencing factors of microplastic distribution in the mangrove ecosystem, and the fate of microplastics in the mangrove ecosystem. Finally, the research directions for microplastics in the mangrove ecosystem are discussed. Six studies were proposed to establish microplastic monitoring methods and detection standards, evaluate the ecological risks of microplastics in mangroves, establish measures for microplastic pollution control and management, predict microplastic models, explore remediation and removal strategies, and study the interaction between microplastics and carbon cycling in marine ecosystems. This study provides references for future research priorities and pollution control in the field of microplastics in mangroves. [ABSTRACT FROM AUTHOR]

Objective To investigate the spectral CT imaging performance of Rhenium sulfide (ReS2) nanoparticles and their effect on photothermal therapy in breast cancer cells. Methods ReS2 nanoparticles were synthesized by one-pot method at room temperature. The basic materialistic properties of ReS2 nanoparticles were characterized by X-ray photoelectron spectroscopy, high-resolution transmission electron microscopy and UV absorption spectroscopy. The spectral CT imaging capability of ReS2 nanoparticles with the same molar concentration of iodine at different energies (60-140 keV) was compared. The photothermal conversion ability of nanoparticles was evaluated by measuring the in vitro photothermal warming of aqueous solutions of ReS2 nanoparticles with different mass concentrations (0、20、40、80 and 100 mg/L). Mouse breast cancer cells 4T1 were co-incubated with different mass concentrations of ReS2 nanoparticle aqueous solution (0, 20, 40, 80 and 100 mg/L). The cytotoxicity of nanoparticles was evaluated by MTT experiment and cell photothermal killing experiment. The photothermal cell killing effect of ReS2 nanoparticles was visually observed and analyzed by cytofluorescent staining. Results High-resolution transmission electron microscopy observed that the particle size of the prepared nanoparticles was less than 10 nm. The UV absorption spectrum confirmed the strong absorption of ReS2 at 808 nm. When the energy was in the range of 60-140 keV, the CT imaging effect of ReS2 nanoparticles at equivalent molar concentration was significantly better than that of iohexol solution. The temperature of 500 mg/L ReS2 solution could be increased by 44.90 °C ± 1.2 °C under 808 nm laser irradiation with a power density of 3 W/cm², while the temperature of pure water was only increased by 9.27 °C ± 0.74 °C under the same conditions. Cellular experiments showed that in the absence of laser irradiation, the survival rate of 4T1 cells treated with ReS2 nanoparticles at concentrations of 40-100 mg/L were all greater than 85%. The cell survival rate was also reduced at ReS2 nanoparticle concentrations of 40-100 mg/L compared to the 0- 40 mg/L case under laser irradiation, but the survival rate was already less than 30%. Conclusion ReS2 nanoparticles are simple to prepare, have good biocompatibility and photothermal therapeutic properties, and have strong killing effect on breast cancer cells under NIR laser irradiation, which have good clinical translation potential.

Objective To investigate the clinical application of low-dose scan combined with advanced modeled iterative reconstruction (ADMIRE) algorithm in the brain CT examination. Methods Sixty healthy subjects who received brain CT examination were randomly divided into the regular dosage group and low dosage group, with 30 cases in each group. Cases in the regular dosage group received 120 kV tube voltage and were reconstructed by traditional filtered back projection (FBP) and were labeled as group A. Cases in the low dosage group received 100 kV tube voltage and the data were reconstructed by traditional filtered back projection ( FBP) and the images were labeled as group B. Cases receiving 100 kV tube voltage were calculated by ADMIRE, and the images were labeled as group C. The dose-length product ( DLP) and volume-weighted CT dose index ( CTDivol) were recorded, then we calculated the effective dose (ED) . The image quality of groups A, B, and C were evaluated by subjective and objective methods. Results DLP, CTDivol, and ED in the low dosage group were significant lower than those of the regular dosage group, with statistical difference (all P <0. 05). The objective image quality evaluation showed that the gray value signal-to-noise ratio ( SNR) in the group B was significantly lower than those in groups A and C ( both P <0. 05); the white and gray matter contrast-to-noise ratio in the group B was significantly lower than that in the group C ( P < 0. 05) . The objective image quality evaluation showed that the subjects with images ;,3 points in the groups A, B, and C accounted for 96.7%, 93. 3%, and 96.7%, respectively, with no significant difference between the three groups (all P > 0. 05), indicating that the evaluation system was consistent. Conclusion In the brain CT examinalion, the application of ADMIRE algorithm can significantly reduce radiation dose under the guarantee of the image quality. [ABSTRACT FROM AUTHOR]
