mucopolysaccharidoses are a group of rare mostly autosomal recessive metabolic and genetic disorders. because of the high rate of consanguinity, they are not uncommon in our population. clinical diagnosis is not difficult for experienced physicians, but it is not enough for treatment and prevention measures in the future pregnancies. so, it is necessary to detect the type of mps by measurement ...

gene therapy consists of the introduction of genetic material into cells for a therapeutic purpose. the understanding of the basics of the molecular and cellular mechanisms in disease treatments has resulted in the development of high-tech gene transfer materials with improved therapeutic efficacy. based on the results of more than 2000 clinical trials to date, gene therapy is going to be inclu...

objectives : this study sought to assess the effect of low-level laser (lll) on pain and trismus after impacted mandibular third molar surgery. materials and methods : this double blind controlled clinical trial was conducted on 40 healthy patients with no underlying disease and impacted mesioangular mandibular third molars with the same level of difficulty. the patients were divided into two g...

conclusions eudragit coated nanoparticle of chitosan is an efficient choice for oral delivery of dna to upper part of gi tract. results the mean size and zeta potential of particles were 300 ± 4 nm and 14 ± 0.5 mv, respectively. encapsulation of this system was 89.6 ± 1.2%. dna release from batches was less than 12% at ph = 5.2 and more than 60% at ph = 6.8 with significant difference of p < 0....

background type 1 diabetes mellitus is one of the metabolic diseases that cause insulin-producing pancreatic ß cells be destroyed by immune system self-reactive t cells. recent­ly, new treatment methods have been developed including use of the stem cells, ß islet cells transplantation and gene therapy by viral and non-viral gene constructs. objectives the aim of this project was preparing the n...

materials and methods: young adult sprague-dawley rats (200-250g) were assigned into one of the three different groups of control, sci, and adenovirus transfer (ad) (n=3/ group). control rats received no injury, nor any surgery. for sci rats, sci was produced by a 10g brass rod with a tip diameter of 2 mm which was dropped from a height of 12.5 mm onto exposed spinal cord at level of t10 with n...

objective(s):diabetic nephropathy is an important long-term complication of diabetes mellitus which appears to be partially mediated by an increase in secretion of transforming growth factor-β (tgf-β). fibromodulin, the small leucine-rich proteoglycan, has been proposed to be the potent tgfβ1 modulator. in this study, the therapeutic effects of recombinant adenoviral vectors expressing fibromod...

objective(s): lipid-based nanoparticles (nlp) are pegylated carriers composed of lipids and encapsulated nucleic acids with a diameter less than 100 nm. the presence of peg in the nlp formulation improves the particle pharmacokinetic behavior. the purpose of this study was to prepare and characterize nlps containing mdr1 sirna and evaluate their cytotoxicity and cellular uptake. mdr1 sirna coul...
