A novel method of generating hydrogel particles for various applications including drug delivery purposes was developed. This method is based on the production of hydrogel particles from sprayed polymeric nano/microdroplets obtained by a nebulization process that is immediately followed by gelation in a crosslinking fluid. In this study, particle synthesis(More)
RNA interference has emerged as a potentially powerful tool in the treatment of genetic and acquired diseases by delivering short interfering RNA (siRNA) or microRNA (miRNA) to target genes, resulting in their silencing. However, many physicochemical and biological barriers have to be overcome to obtain efficient in vivo delivery of siRNA and miRNA(More)
Curcumin, a yellow polyphenol derived from the turmeric Curcuma longa, has been associated with a diverse therapeutic potential including anti-inflammatory, antioxidant, antiviral, and anticancer properties. However, the poor aqueous solubility and low bioavailability of curcumin have limited its potential when administrated orally. In this study, curcumin(More)
The thermal behavior, phase stability, indicative stability and intrinsic dissolution rates of a series of cocrystals and cocrystal hydrates derived from the pharmaceutically active ingredient acetazolamide (ACZ) and 2-aminobenzamide (2ABAM), 2,3-dihydroxybenzoic acid (23DHBA), 2-hydroxybenzamide (2HBAM), 4-hydroxybenzoic acid (4HBA), nicotinamide (NAM) and(More)
The RNA interference (RNAi) constitutes a conservative mechanism in eukaryotic cells that induces silencing of target genes. In mammalians, the RNAi is triggered by siRNA (small interfering RNA) molecules. Due to its potential in silencing specific genes, the siRNA has been considered a potential alternative for the treatment of genetic and acquired(More)
Dapsone, formerly used to treat leprosy, now has wider therapeutic applications. As is the case for many therapeutic agents, low aqueous solubility and high toxicity are the main problems associated with its use. Derivatization of its amino groups has been widely explored but shows no significant therapeutic improvements. Cocrystals have been prepared to(More)
