Protection of photosynthesis and antioxidative system by 24-epibrassinolide in Solanum melongena under cold stress

open access: yes, 2014
This study was carried out to understand the mechanism of protection of plants under cold stress by exogenous 24-epibrassinolide (EBR). The eggplant (Solanum melongena L.) seedlings were pretreated with five concentrations of EBR (0, 0.05, 0.1, 0.2 and 0.

A narrow bandgap Schottky heterojunction Fe2N/CeO2 microneedle triggering sonodynamic reactive oxygen species storm for drug‐resistance‐free skin fungal infection

open access: yesBMEMat, EarlyView.
Inorganic sonosensitizers suffer from inefficient electron‐hole separation, rapid recombination, and wide bandgaps in anti‐fungal applications. We propose MN@Fe2N/CeO2 to directly eliminate fungi without drug resistance. Combining semiconductor CeO2's advantages with Fe2N's high work function and activity enables efficient Schottky heterojunctions ...

Multifunctional polycaprolactone‐based composite fibers with icariin and glutathione for effective repair of critical‐sized bone defects

open access: yesBMEMat, EarlyView.
A multifunctional PCL‐based scaffold co‐delivering Icariin and Glutathione synergistically enhances osteogenesis, angiogenesis, and oxidative stress resistance, achieving near‐complete repair of critical‐sized bone defects in vivo. This cell‐free platform represents a promising strategy for accelerated bone regeneration.

Electron compensation‐gated nanomotor for immunomodulation and microenvironment remodeling in bacterial pneumonia therapy

open access: yesBMEMat, EarlyView.
A nanomotor featuring an “electronic lock” via electron compensation in an Au‐Ag alloy ensures therapeutic precision. Near‐infrared light acts as a key, unlocking on‐demand Ag+ release for synergistic bactericidal action and microenvironment remodeling to potently treat bacterial pneumonia. Abstract Bacterial pneumonia treatment is severely hampered by

Antioxidants in Infection

open access: yesJournal of Nutritional Science and Vitaminology, 1993
Endogenous oxidation reactions are essential for the normal biochemistry of life and are especially critical for leukocyte microbial killing mechanisms in host defense to infectious diseases. However, reactive oxidative intermediates can damage normal tissues unless kept under antioxidant control.
