Immobilized Lipase Based on Hollow Mesoporous Silicon Spheres for Efficient Enzymatic Synthesis of Resveratrol Ester Derivatives.

Enzymatic esterification of resveratrol is crucial for its potential application in lipophilic foods and drugs. However, the poor activity of the free enzyme hinders the reaction. In this work, the highly efficient enzymatic synthesis of resveratrol ester derivatives was achieved by immobilized lipase on hydrophobic modified hollow mesoporous silicon spheres (HMSS-C).

Electrospun Zein/Thyme Essential Oil-Based Membranes as an Effective Antibacterial Wound Dressing.

Wound dressings are an important element in promoting the healing of wounds. Electrospun fibrous materials have a highly porous structure and controllable antibacterial activity and are therefore popular as potential wound dressings. However, electrospun fibrous wound dressings are usually conveniently packaged for immediate use but cannot accommodate irregularly shaped wounds, and their misuse runs the risk of causing a secondary injury to the wound.

Performance of polyvinyl pyrrolidone-isatis root antibacterial wound dressings produced in situ by handheld electrospinner.

Antibacterial dressings are an increasingly important tool for the prevention and management of wound infections, particularly in light of concerns surrounding conventional drug-resistant antibiotics. Handheld electrospinning devices provide opportunities for the rapid application of antibacterial dressing materials to wounds, but spinning formulations need to be compatible with live biological surfaces. We report the development of a new antibacterial formulation compatible with handheld electrospinning, and its manufacture directly on a wound site.

Inhibition of Grass Carp Reovirus Infection by DNA Aptamers against S10 Protein.

Grass Carp reovirus (GCRV) is one of the most pathogenic agents among aquareovirus isolates and has the ability to cause a severe epidemic outbreak of hemorrhagic disease, thus resulting in both a high mortality rate during the culture of Grass Carp Ctenopharyngodon idella and an enormous economic loss. Aptamers have been demonstrated to have strong promising applications in antiviral drug development. In the present study, a complementary DNA fragment encoding the S10 gene of GCRV was cloned.
