Second‐Generation Organic Nanozyme for Effective Detection of Agricultural Herbicides

Advanced Sustainable Systems, EarlyView.
A sustainable organic nanozyme‐based colorimetric sensing platform is developed for detecting toxic agrichemicals. The second‐generation EU nanozyme, synthesized via a modified self‐assembly process, exhibits peroxidase‐like activity, degradability, and biocompatibility.

Zinc and Copper Levels in Patients with Primary Hypertension and Normotension [PDF]

, 2015
One of the causes of primary hypertension is an exposure to free radicals. The formation of free radicals in the body can be prevented by taking antioxidants. Zinc and copper are cofactors of endogenous antioxidant enzyme superoxide dismutase. This study

Dual Charge Transfer Mechanisms in Intimately Bonded S‐scheme Heterojunction Photocatalyst with Expeditious Activity toward Environmental Remediation

Advanced Sustainable Systems, EarlyView.
A novel MBOdCN S‐scheme heterojunction photocatalyst is fabricated using pristine Mg‐Bi2O3 and grayish g‐C3N4, where dynamic dual charge migration paths occur to accelerate exciton dissociation. This composite catalyst realizes high degradation efficiency of up to 99.56% of oxytetracycline (OTC) removal under optimized conditions. The material exhibits

ROS‐Driven Nanoventilator for MRSA‐Induced Acute Lung Injury Treatment via In Situ Oxygen Supply, Anti‐Inflammation and Immunomodulation

Advanced Science, EarlyView.
A ROS‐driven in situ oxygen supply nanoventilator based on enzyme nanocapsule can convert ROS into O2 through enzyme cascade reaction between SOD and CAT to relieve lung hypoxia, and kill MRSA by releasing vancomycin, which effectively reduces HIF‐1α expression and balances pro‐inflammatory/anti‐inflammatory macrophages ratio, thereby reducing the ...

Shrimp Virus Regulates ROS Dynamics via the Nrf2 Pathway to Facilitate Viral Replication

Advanced Science, EarlyView.
Viruses manipulate host ROS as a strategy to achieve successful infection. WSSV exploits Nrf2 pathway to maintain ROS homeostasis and establishes a positive feedback loop to facilitate WSSV replication. Wsv220 competitively binds to Keap1 to activate Nrf2. Nrf2 up‐regulates LvG6PDH to produce more NADPH and GSH to eliminate excessive ROS.
