Antioxidants: The new frontier for translational research in cerebroprotection
Journal of Anaesthesiology Clinical Pharmacology, 2014 It is important for the anesthesiologist to understand the etiology of free radical damage and how free-radical scavengers attenuate this, so that this knowledge can be applied to diverse neuro-pathological conditions. This review will concentrate on the

Multiple free-radical scavenging capacity in serum [PDF]
Journal of Clinical Biochemistry and Nutrition, 2012 We have developed a method to determine serum scavenging-capacity profile against multiple free radical species, namely hydroxyl radical, superoxide radical, alkoxyl radical, alkylperoxyl radical, alkyl radical, and singlet oxygen. This method was applied to a cohort of chronic kidney disease patients.

X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites
Advanced Functional Materials, EarlyView.We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...

Advanced Functional Materials, EarlyView.Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights

Use of the sunscreen for the degradation of a toxic methyl blue dye with hydrogen peroxide
Scientific ReportsTo protect against sunlight, the sunscreen (SC) is widely used, and here we demonstrate their novel application in environmental remediation. SC effectively degraded the toxic dye methyl blue (MBD) from aqueous solution under a household bulb within 18 ...

Advanced Functional Materials, EarlyView.Thioketal (TK) polymers are promising biomaterials due to their selective biodegradation by reactive oxygen species (ROS), but they respond slowly to physiologic doses of ROS. Here, the TK bond's pendant groups are modified to enhance the degradation of TK‐based implants both in vitro and in vivo.

Mechanoluminescent HOF Nanotransducers Enabled Sono‐Optogenetics in Parkinsonian Rats
Advanced Functional Materials, EarlyView.We present a mechanoluminescent system utilizing porous hydrogen‐bonded organic frameworks (HOFs) as a toolkit for focused ultrasound‐triggered, non‐invasive light delivery to the deep brain in rats. This approach enables the specific activation of PV‐GPe neurons in dopamine‐depleted Parkinson's disease rat models, resulting in a comparable alleviation

Free Radical Scavenging Activity of Elsholtzia densa
Journal of Acupuncture and Meridian Studies, 2012 Medicinal plants have been used traditionally to cure a variety of diseases since ancient times. Elsholtzia densa, a rare annual herb of the Kashmir valley, was assessed for its antioxidant efficacy. Antioxidant activity of the crude extracts was evaluated using 1, 1- diphenyl-2-picryl hydrazyl free radical (DPPH), DNA sugar damage, lipid peroxidation,

Advanced Functional Materials, EarlyView.Magnetic‐field‐assisted CVD of heterometallic single‐source precursors modulates thin‐film surface electronic structure and interfacial charge transfer. Field‐grown (Cobalt ferrite‐1T)CF‐1T films exhibit stabilized electronic states, lower kinetic barriers, and markedly enhanced nitrate‐to‐ammonia electrocatalysis versus (Cobalt ferrite‐0T) CF‐0T ...
