Synthesis of unique three-dimensional CoMnO@Ni(OH) nanocages via Kirkendall effect for non-enzymatic glucose sensing.

Transition metal oxides / hydroxides, which have the advantages of wide distribution, low price, low toxicity, and stable chemical properties, have attracted much attention from researchers. Therefore, this work reports the construction of the unique CoMnO nanocages assisted by the Kirkendall effect, and worm-like Ni(OH) nanoparticles were grown on the surface via hydrothermal method, the final product CoMnO@Ni(OH) nanocages were applied to construct efficient and sensitive non-enzymatic glucose electrochemical sensing. The stable three-dimensional hollow CoMnO nanocages structure, not only can provide a wider specific surface area and more abundant active sites, its porous structure also can effectively inhibit the aggregation of nanoparticles, increase the ion diffusion path, shorten the electron transport distance, and improve the electrical conductivity.

Therapeutic potential and mechanism of Dendrobium officinale polysaccharides on cigarette smoke-induced airway inflammation in rat.

Chronic obstructive pulmonary disease (COPD) is among the leading causes of death worldwide, and is characterized by persistent respiratory symptoms and airflow limitation due to chronic airway inflammation. Cigarette smoking is a major risk factor for COPD. This study aims to determine the therapeutic effects of polysaccharides extracted from Dendrobium officinale (DOPs), a valuable traditional Chinese Medicinal herb, on cigarette smoke (CS)-induced airway inflammation in a rat passive smoking model.
