Dynamic Metabolic Characterization of Lung Tissues in Rats Exposed to Whole-Thorax Irradiation Based on GC-MS.

An animal model of radiation-induced lung injury (RILI) was established using female rats given sublethal whole-thorax X-ray irradiation (15 Gy) at a dose rate of 2.7 Gy/min. The rats were studied for up to day 45 and compared with sham-irradiated controls.

TiCT MXene nanoribbons@MnO: A novel multifunctional probe for colorimetric and fluorescence dual-response sensing of trichlorfon.

Manganese dioxide nanosheets (MnO NSs) have garnered significant attention in analytical sensing, while the majority of the previous reports suffer from a complex preparation process involving reducing agents, template or high-temperature. In this work, a novel MnO NSs decorated TiCT MXene nanoribbons (TiCTNR@MnO) composite was firstly assemblied via a facile one-step strategy and applied as a bi-signal generator to enable colorimetric and fluorescence (FL) dual-response sensing. During the assembly process, TiCTNR innovatively acted as both reductant and carrier to prevent the aggregation of MnO NSs.

Rapid and precise treatment selection for antimicrobial-resistant infection enabled by a nano-dilution SlipChip.

Antimicrobial resistance (AMR) has become an increasingly severe threat to global health, and AMR-associated infection is one of the leading causes of death around the world. Due to the long turnaround time and the limited flexibility and availability of current antimicrobial susceptibility testing (AST) methods, a large portion of patients with bacterial infections are still treated empirically, increasing the risk of mistreatment. To address the demand for precision treatment of bacterial infections, we developed a nano-dilution SlipChip (nd-SlipChip)-based systematic evaluation method, which facilitates rapid, logic feedback for the assessment of antibiotics, antibiotic combinations, and phage therapy.

Revolutionising Cancer Immunotherapy: Advancements and Prospects in Non-Viral CAR-NK Cell Engineering.

The recent advancements in cancer immunotherapy have spotlighted the potential of natural killer (NK) cells, particularly chimeric antigen receptor (CAR)-transduced NK cells. These cells, pivotal in innate immunity, offer a rapid and potent response against cancer cells and pathogens without the need for prior sensitization or recognition of peptide antigens. Although NK cell genetic modification is evolving, the viral transduction method continues to be inefficient and fraught with risks, often resulting in cytotoxic outcomes and the possibility of insertional mutagenesis.
