Analysis of the catalytic activity of identical mutations in the catalytic cores of nHH8, a very active "extended" hammerhead, and HH16, a less active "minimal" hammerhead, reveal that the tertiary Watson-Crick base pair between C3 and G8 seen in the recent structure of the Schistosoma mansoni extended hammerhead can be replaced by other base pairs in both backgrounds. This supports the model t...

Synergistic and cooperative phenomena in catalysis are defined here via a formal classification of the catalytic systems, using the combination of game theory and hyperstructure theory. Game theory is based on the idea that players are rational decision-makers; therefore, making a transposition is reported as rational, the chemical choice. Three catalytic reactions are considered as characteris...

A photoresponsive nanozyme with peroxidase- and catalase-like activities, photodynamic photothermal properties is designed in article number 2007090 by Huiyu Liu co-workers. Its synergistic catalytic therapy dual phototherapy show unique advantages for tumor treatment.

Abstract The excessive using of fossil energy has caused serious environmental pollution, and the development utilization new sources have been a continuing research direction concern. synergistic effect Ni Fe is beneficial to reduce reaction barrier oxygen evolution (OER), therefore NiFe based catalyst represents very promising non‐precious metal OER catalyst. This minireview focuses on optimi...

Graphene quantum dots (GQDs), as metal-free carbon nanomaterials, have potential applications in electrochemical fields due to their strong chemical inertness, oxygen-rich functional groups and remarkable quantum confinement and edge effects. Herein, we demonstrate that a novel metal-free electrode composed of GQDs and multi-walled carbon nanotubes (MWCNTs) exhibits a significant synergistic ef...

objective(s) sonodynamic therapy is a physical treatment which utilizes ultrasound waves with an appropriate sensitizer such as protoporphyrin ix (ppix). the activation of sensitizer depends on cavitation, and therefore, high intensity ultrasound is an important necessity. beside, high intensity ultrasound can induce side effects on the healthy tissues which have surrounded tumor. the particles...

Photothermal-Gas Synergistic Cancer Therapy In article number 2206749, Benhui Hu, Yun Liu, and co-workers propose a cascade reaction-promoted CO release strategy to realize augmented photothermal-gas synergistic cancer therapy. Gold-based porphyrinic coordination polymer nanosheets synthesized by simple aqueous phase reaction, with ultrasmall zero-valent gold as the node, have advantages of hig...

Mannitol (M) and deferoxamine (DFO) can each protect against myohemoglobinuric acute renal failure (MH-ARF). This study assessed M-DFO interactions during MH-ARF to help discern mechanisms of renal injury, and to define whether M + DFO exerts additive or synergistic antioxidant/cytoprotective effects. Rats subjected to the glycerol model of MH-ARF were treated with (a) M; (b) DFO; (c) M + DFO; ...
