Antisense oligonucleotides (ASOs) have promising therapeutic potential in oncotherapy. However, low stability and efficacy limit their application in the clinic. Cationic liposomes have been investigated as delivery vehicles for ASOs. Here, we report the synthesis and evaluation of an ASO delivery vehicle comprising cationic liposomes incorporating fatty(More)
Inspired by natural columnar nacre, artificial montmorillonite/hydroxyethyl cellulose columnar nacre-like materials with a site-specific layered structure in the interior and a hierarchical columnar structure on the surface are prepared. The materials exhibit improved tensile strength, good chemical stability in seawater, superior resistance to sand-grain(More)
Anisotropic slippery surfaces composed of directional, porous, conductive poly(3-hexylthiophene) (P3HT) fibers, and silicone oil exhibit excellent anisotropic sliding properties for several liquid droplets and the reversible control of conductive liquid droplets sliding on these surfaces under the application of voltage.
Microfluidically (MF) synthesized lipid nanoparticles (LNPs) for antisense oligonucleotides (ODN) delivery have been shown to be superior to those prepared by bulk mixing (BM). In this study, a 5-inlet MF chip was used to synthesize LNPs loaded with LOR-2501, an antisense ODN targeting the ribonucleotide reductase R1 subunit. The size distribution of ODN-(More)
The sufficiency of hard and soft tissue at the implant site is the guarantee of long-term function, health and the appearance of implant denture. Problem of soft tissue recession at the implant site has always been bothering dentists. Traditional methods for augmentation of soft tissue such as gingival transplantation have disadvantages of instability of(More)
A single subcooled jet of water which undergoes boiling upon impingement on a discrete heat source is studied experimentally using time-resolved stereo particle image velocimetry (PIV). The impinging jet issues from a 3.75 mm diameter sharp-edged orifice in a confining orifice plate positioned 4 orifice diameters from the target surface. The behavior at jet(More)
Bcl-2 is an anti-apoptotic gene that is frequently overexpressed in human cancers. G3139 is an antisense oligonucleotide against bcl-2 that has shown limited efficacy in clinical trials. Here, we report the synthesis of a new antisense oligonucleotide containing additional chemical modifications and its delivery using nanoparticles. An oligonucleotide(More)
Ordered porous polymeric films attract more and more attention because they have many advantages and broad application prospects in many fields. But because of their large flexibility and poor mechanical properties, some of the scope for application is greatly limited. Inspired by the ordered pore structure of the honeycomb and the layered structure of(More)
In this paper, we investigated the wettability and adhesive behavior of the natural honeycomb wall for water and honey droplets. The cell walls have hydrophobic and highly adhesive properties for both water and honey in air. This highly adhesive cell wall was used as a "mechanical hand" to transfer micro-droplets. These findings will help us to(More)
