it has been observed that most of the chemical entities have high lipophilicity and poor aqueous solubility, which result in poor bioavailability. in order to improve the bioavailability, the release behavior of such drugs should be improved. although there are numerous techniques to handle solubility related issue, but they are expensive due to involvement of complicated equipments, advanced m...
Nucleic acid-based therapy is a growing field of drug delivery research. Although ultrasound has been suggested to enhance transfection decades ago, it took a combination of ultrasound with nucleic acid carrier systems (microbubbles, liposomes, polyplexes, and viral carriers) to achieve reasonable nucleic acid delivery efficacy. Microbubbles serve as foci for local deposition of ultrasound ener...
introduction worldwide, chronic liver disease is a major cause of morbidity and mortality. causes of elevated serum alanine aminotransferase (alt) levels vary depending on the population under study. the aim of this study is to evaluate the frequency and causes of persistently elevated alt levels in patients of the gastroenterology (gi) clinics in ghaem and emam reza hospitals in mashhad, iran....
thermodynamic features related to preparation and use of self-assemblies formed between multilamellar and unilamellar zwitterionic liposomes and polynucleotides with various conformation and sizes are presented. the divalent metal cation or surfactant-induced adsorption, aggregation and adhesion between single- and double-stranded polyribonucleotides and phosphatidylcholine vesicles was followe...
Crowell, Richard L. (Hahnemann Medical College, Philadelphia, Pa.). Specific viral interference in HeLa cell cultures chronically infected with Coxsackie B5 virus. J. Bacteriol. 86:517-526. 1963.-The presence of large amounts of Coxsackie B5 virus in culture fluids of a HeLa subline, serially propagated over a 3-year period, provided evidence for attainment of a viral carrier state. Human serum...
BACKGROUND Gene silencing in the retina using RNA interference could open broad possibilities for functional studies of genes in vivo and for therapeutic interventions in eye disorders. Therefore, there is a considerable demand for protocols to deliver siRNA into the vertebrate retina. In this work we explored a possibility to deliver synthetic 21 bp siRNA into the mouse retina after intravitre...
Cystic fibrosis (CF) is an autosomal recessive disorder caused by mutations in CFTR genes that affect chloride ion channel. The CF is a good nominee for gene therapy as the asymptomatic carriers are phenotypically normal, and the desired cells are accessible for vector delivery. Gene therapy shows promising effects involving the correction of gene or replacement of the mutant gene with the func...
Targeted gene delivery systems have attracted great attention due to their potential in directing the therapeutic genes to the target cells. However, due to their low efficiency, most of the successful applications of polymeric vectors have been focused on genes which can achieve robust expression. Minicircle DNA (mcDNA) is a powerful candidate in terms of improving gene expression and prolongi...
