Revealing the bioavailability and phytotoxicity of different particle size microplastics on diethyl phthalate (DEP) in rye (Secale cereale L.).

Understanding how widely distributed microplastics (MPs) and diethyl phthalate (DEP) interact with crops remains limited, despite their significant implications for human exposure. We used physiology, transcriptomics, adsorption kinetics, and computational chemistry to assess rye's molecular response to two sizes of MPs (200 nm and 5 µm) and DEP, both individually and in combination. Findings systematically highlight potential ecological risks from MPs and DEP, with ecotoxicity ranking as follows: CK (Control Check) < LMPs < SMPs < DEP < LMPs+DEP < SMPs+DEP.

NIR-propelled Janus nanomotors for active photoacoustic imaging and synergistic photothermal/chemodynamic therapy.

Synthetic nanomotors have great application potential in deep tissue imaging and tumor treatment due to their active movement ability. Herein, a novel near infrared (NIR) light-driven Janus nanomotor is reported for active photoacoustic (PA) imaging and synergistic photothermal/chemodynamic therapy (PTT/CDT). Au nanoparticles (Au NPs) are sputtered on the half-sphere surface of copper-doped hollow cerium oxide nanoparticles after bovine serum albumin (BSA) modification.

3D hierarchical LDHs-based Janus micro-actuator for detection and degradation of catechol.

Micro/nanomotors that combine the miniaturization and autonomous motion have attracted much research interest for environmental monitoring and water remediation. However, it is still challenging to develop a facile route to produce bifunctional micromotors that can simultaneously detect and remove organic pollutants from water. Herein, we developed a novel Janus micromotor with robust peroxide-like activity for simultaneously colorimetric detection and removal of catechol from water.

Three-Dimensional Hierarchical HRP-MIL-100(Fe)@TiO@FeO Janus Magnetic Micromotor as a Smart Active Platform for Detection and Degradation of Hydroquinone.

A novel multifunctional Janus magnetic micromotor was designed and constructed by using MIL-100(Fe)@TiO@FeO multicore-shells modified with horseradish peroxidase (HRP) as a smart active platform to realize detection and degradation of hydroquinone (HQ). The obtained micromotor showed a unique three-dimensional (3D) hierarchical architecture with highly exposed active sites and could autonomously move at a speed of 140 ± 7.0 μm·s by O bubbles generated from the catalytic decomposition of HO fuel.

Glutaredoxin like protein (RtGRL1) regulates HO and Na accumulation by maintaining the glutathione pool during abiotic stress.

Reaumuria trigyna, an endangered recretohalophyte, is a small archaic wild shrub endemic to arid and semiarid plateau regions of Inner Mongolia, China. Based on salt-related transcriptomic data, we isolated a GRX family gene, glutaredoxin like protein (RtGRL1), from R. trigyna that is associated with the removal of active oxygen and regulation of redox status.

Application of Gastroscopy Based on Nano Carbon in the Remedy of Chronic Pulmonary Heart Disease Caused by Helicobacter Pylori.

Chronic pulmonary heart disease is a common respiratory disease. Helicobacter pylori infection can lead to the occurrence of chronic pulmonary heart disease. However, most drugs for chronic pulmonary heart disease caused by helicobacter pylori are lack of tissue specificity.
