Nanotechnology has provided a novel approach for the preparation of a safe and highly effective pesticide formulation. Thiazole-Zn, a widely used bactericide, was successfully prepared at nanoscale by an innovative approach of final synthesis process control. Its plausible formation mechanism based on restricted particle aggregation in a nanoreactor was elucidated. Then in order to assess the application performance of thiazole-Zn nanoparticle, the nanoformulation (NPF) was conveniently formulated. Interestingly, the physicochemical properties of NPF showed better than that of the commercial pesticide formulation (CPF) in dispersibility, wettability, spreadability, and stability. At the same time, the in vitro bioassay showed that the minimum inhibitory concentrations (MICs) of NPF against pv (), pv (), subsp. (Jones) Holland (), and pv () were 46.88, 93.75, 93.75, and 375.00 mg/L, respectively, whereas those of CPF were 93.75, 375.00, 375.00, and 875.00 mg/L, respectively. Therefore, NPF exhibited stronger antibacterial activity against the above-mentioned pathogens. Moreover, NPF was more effective to bacterial blight of rice than CPF in field trial. As a conclusion, nanotechnology for pesticides by synthesis process control will have a potential in improving the utilization efficiency and relieving the corresponding environmental pollution.

CRISPR-Cas9 gene editing technology, as an innovative biomedical tool, holds significant potential in the prevention and treatment of atherosclerosis. By precisely editing key genes such as PCSK9, CRISPR-Cas9 offers the possibility of long-term regulation of low-density lipoprotein cholesterol (LDL-C), which may reduce the risk of cardiovascular diseases. Early clinical studies of gene editing therapies like VERVE-101 have yielded encouraging results, highlighting both the feasibility and potential efficacy of this technology.

This review explores the current understanding and recent advancements in neuroblastoma, one of the most common extracranial solid pediatric cancers, accounting for ~ 15% of childhood cancer-related mortality. The hallmarks of NBL, including angiogenesis, metastasis, apoptosis resistance, cell cycle dysregulation, drug resistance, and responses to hypoxia and ROS, underscore its complex biology. The tumor microenvironment's significance in disease progression is acknowledged in this study, along with the pivotal role of cancer stem cells in sustaining tumor growth and heterogeneity.
