Delivery system

Astaxanthin (AST) and pycnogenol (PYC) are natural bioactive compounds commonly used in pharmaceuticals and functional foods due to their highly antioxidant activity and potential health benefits. However, the widespread application of astaxanthin is hindered by its poor water solubility and highly unsaturated structure. In this study, nanoparticles co-delivering astaxanthin and pycnogenol (NAP) were fabricated to enhance the dispersibility, stability, and bioavailability of astaxanthin.

The nasal route for drug administration has the potential for local and systemic delivery of a wide variety of therapeutics. Nasal spray drug delivery has the potential to administer drugs to the bloodstream, avoiding the use of painful needles. While there is great potential, studies in the area are limited and somewhat conflicting. This study aimed to support the improvement of nasal drug delivery through experimental work on a model nasal cavity and through experimental characterisation of nasal spray behaviour. Four different brands of nasal spray were investigated.

We have analyzed the response of a number of human cell lines to treatment with antisense oligodeoxynucleotides (ODNs) directed against RNA polymerase II, replication protein A, and Ha-ras. ODN-delivery to the cells was liposome-mediated or via electroporation, which resulted in di€erent intracellular locations of the ODNs. The ODN-mediated target mRNA reduction varied consider-ably between the cell lines.

Special oligonucleotides for targeted gene correction have attracted increasing attention recently, one of which is the chimericRNAÆDNAoligonucleotide (RDO) system. RDOs for targeted gene correction were first designed in 1996, and are typically 68 nucleotides in length including continuous RNA andDNA sequences (RNA is 2¢-O-methyl-modified).

a2 -Macroglobulin (a2M) is an abundant glycoprotein with the intrinsic capacity for capturing diverse proteins for rapid delivery into cells. After internalization by the receptor-mediated endocytosis,a2M-protein complexes were rapidly degraded in the endolysosome system. Although this is an importantpathway for clearanceofbotha2Mandbiological targets, little is known about the nature ofa2M degradation in the endolysosome system.

A bio-nanocapsule (BNC), composed of the surface antigen (sAg) of the hepatitis B virus, is an efficient nanomachine with which to accomplish the liver-specific delivery of genes and drugs. Approximately 110 molecules of sAg are associated to form a BNC particle with an average diameter of 130 nm. TheLprotein is an sAg peptide composed mainly of preS and S regions. The preS region, with specific affinity for human hepatocytes, is localized in the N-terminus.

Glutamine is an essential amino acid for enterocytes, especially in states of critical illness and injury. In several studies it has been speculated that the beneficial effects of glutamine are dependent on the route of supply (lumi-nal or systemic). The aim of this study was to investigate the relevance of both routes of glutamine delivery toin vitro intestinal cells and to explore the molecular basis for proposed beneficial glutamine effects: (a) by deter-mining the relative uptake of radiolabelled glutamine in Caco-2 cells;...
