Article Abstract
Background: Molybdenum diselenide (MoSe), as a nano near-infrared absorber, has been widely studied in the field of photothermal therapy of cancer. However, there is little research on its application in the treatment of human choriocarcinoma.
Methods And Results: In this paper, a new type of carbon-coated MoSe (MEC) nanoparticles was prepared by a one-step hydrothermal method. The chemical characterization including SEM, TEM, EDS, XRD, FT-IR, TGA, Roman, and XPS showed that MEC was successfully synthesized. MEC exhibited a high photothermal conversion efficiency (50.97%) and extraordinary photothermal stability under laser irradiation. The cell experiment results showed that MEC had good biocompatibility on normal cells while significant photothermal effect on human choriocarcinoma (JEG-3) cells, achieving a good anticancer effect. The level of reactive oxygen species (ROS) in JEG-3 cells was significantly increased under the combination of MEC nanoparticles and near-infrared radiation. MEC nanoparticles could induce apoptosis of JEG-3 cells in combination with near-infrared radiation. Finally, transcriptomic analysis verified that MEC combined with laser radiation could inhibit DNA replication and induce apoptosis, thus improving its therapeutic effect on human choriocarcinoma.
Conclusion: MEC nanoparticles exert an excellent photothermal effect and may become an important candidate drug for the treatment of human choriocarcinoma.

Leishmaniasis, caused by protozoa of the genus , is a major global health issue due to the limitations of current treatments, which include low efficacy, high costs, and severe side effects. This study aimed to develop a more effective and less toxic therapy by utilizing zein nanoparticles (ZNPs) in combination with a nonpolar fraction (DCMF) from (Syn. ), a plant rich in dimeric flavonoids called brachydins.

High-performance and cost-efficient electrocatalysts and electrodes are needed to improve the hydrogen evolution reaction (HER) for the hydrogen (H) generation in electrolysers, including microbial electrolysis cells (MECs). In this study, free-standing carbon nanofiber (CNF) films with supported cobalt phosphide nanoparticles have been prepared by means of an up-scalable electrospinning process followed by a thermal treatment under controlled conditions. The produced cobalt phosphide-supported CNF films show to be nanoporous (pore volume up to 0.

Article Synopsis
- - Long-term exposure to nanopolystyrenes (PS-NPs) in organisms causes neurotoxicity, leading to impaired movement and sensory perception, particularly at higher concentrations.
- - In a study using the worm model Caenorhabditis elegans, quercetin was found to improve locomotion and sensory behavior while protecting against neurodegeneration caused by PS-NPs exposure, suggesting its potential as a neuroprotective agent.
- - Quercetin treatment increased dopamine levels and altered gene expression related to neurodegeneration and dopamine metabolism, indicating its role in countering PS-NPs toxicity on neuronal function.

Increasing evidence has suggested that nanoplastic pollution has become a global concern. More importantly, transgenerational toxicity can be induced by nanoplastics at predicted environmentally relevant doses (ERDs). Considering that amino modification could increase nanoplastic toxicity, we compared transgenerational neurotoxicity between pristine polystyrene nanoparticle (PS-NP) and amino-modified PS-NP (NH-PS-NP) in .

One of the main barriers to MEC applicability is the bacterial anode. Usually, the bacterial anode contains non-exoelectrogenic bacteria that act as a physical barrier by settling on the anode surface and displacing the exoelectrogenic microorganisms. Those non-exoelectrogens can also compete with exoelectrogenic microorganisms for nutrients and reduce hydrogen production.
