Tetrahedral Framework Nucleic Acid-Based Delivery of DJ-1-saRNA Prevent Retinal Ischaemia-Reperfusion Injury via Inhibiting Ferroptosis.

Retinal ischaemia/reperfusion injury (RI/RI) is the primary pathophysiological mechanism underlying retinal ischaemic diseases, potentially resulting in significant and irreversible visual impairment. Currently, there are no effective treatments available for RI/RI, and oxidative stress is a critical factor that contributes to the associated damage. DJ-1, an important endogenous antioxidant, has been proposed as a promising therapeutic agent for RI/RI owing to its potential for overexpression.

The Protective Effect of Esculentoside A on MPL/lpr Mice by Upregulating the Expression of CD19+IL-35+Breg Cells and Interleukin-35.

Introduction: Esculentoside A (EsA) is one of the main components of the traditional Chinese medicine Phytolacca esculenta. The possible mechanism of action of EsA in the treatment of lupus nephritis (LN) was explored by observing the effects of EsA on CD19+ IL-35+regulatory B (IL-35+Breg) cells.

Methods: Twenty-four MRL/lpr mice were randomly divided into control, EsA, and EsA+IL-12p35 antibody groups.

Melting centrifugally spun ultrafine poly butylene adipate--terephthalate (PBAT) fiber and hydrophilic modification.

This paper demonstrates that melt centrifugal spinning could be used to effectively fabricate degradable poly (butylene adipate--terephthalate) (PBAT) fibers with uniform fiber diameter. The hydrophobic PBAT fibers were modified into hydrophilic fibers using the hyperbranched polyesters (HBP) with three-dimensional molecular chain structures and a large number of functional groups at the chain ends. The structures and properties of the obtained fibers were characterized with SEM, XRD, DSC, contact angle, and tensile strength analyses.

Biodegradable, biomimetic, and nanonet-engineered membranes enable high-flux and highly-efficient oil/water separation.

Porous membranes with fascinating super-wettable surface and tunable porous architecture for oil-water separation have been developed rapidly, however, the serious secondary marine pollution caused by the non-degradable defectiveness of membranes themselves is still a thorny problem. Herein, we create an eco-friendly membrane with biomimetic cobweb-like nanostructure via assembling two-dimensional bacterial cellulose nanonets on the starch nanofibrous membrane on a large scale. The obtained novel composite membranes exhibit integrated properties of sub-micron pore size, ultrahigh porosity, superhydrophilicity, and underwater superoleophobicity, stemming from the synergistic effect of the hydrated nanonet-skin-layer and porous starch matrix.

Cross-Linking of Centrifugally Spun Starch/Polyvinyl Alcohol (ST/PVA) Composite Ultrafine Fibers and Antibacterial Activity Loaded with Ag Nanoparticles.

In this research, centrifugally spun ultrafine composite starch/polyvinyl alcohol (ST/PVA) fibers with high water stability were prepared by cross-linking with a mixture of glutaraldehyde and formic acid in the form of vapor phase. The effect of cross-linking temperature combined with time on the water stability, crystal structure, and thermal properties of fibers was investigated to obtain the optimum parameters. On this basis, we further prepared Ag-loaded ST/PVA fibers with different contents of nano silver.

Cobalt-catalyzed Divergent Markovnikov and Anti-Markovnikov Hydroamination.

Catalytic hydroamination of the readily available alkenes is among the most straightforward means to construct diverse alkyl amines.
