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 functional one. Accordingly, various viral and non-viral carriers have been investigated. Although viral vectors are efficient, they have some problems, including mutagenesis, host immune response, higher toxicity, and costliness. On the other hand, non-viral vectors have less toxicity and immunogenic response and are easier to prepare. For a successful gene therapy, the cargo must be delivered to the target site. However, various barriers are faced by non-viral vectors, which make the gene delivery to the target site difficult. Extracellular barrier, which is the first barrier, include nucleases, negatively charged serum proteins, blood cells, and activated immune system. Ciliated epithelium, mucus gel, apical surface glycocalyx, and plasma membrane come in the second category of the barriers. Furthermore, the third category, which is related to the intracellular barriers, includes endosome and lysosome, cytoplasmic nucleases, viscous environment of cytoplasm with different proteins, and finally nuclear membrane. Various approaches have been proposed to increase the systematic delivery of vectors and enhance their efficiency. Some of these approaches include surface coating with inert polymers, modification of surface charge with anionic polymers, and enhancement of endocytosis and reduction of toxicity by using polyethylene glycol. This review paper was conduct to highlight the barriers faced by non-viral vectors when carrying a genetic payload to the lungs. This study also involved the investigation of the strategies and different types of modifications targeted toward the improvement of the efficiency of non-viral vectors.","PeriodicalId":18933,"journal":{"name":"Nanomedicine Journal","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42873816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Metallic nanoparticles, such as gold nanoparticles (AuNPs) have exceptional properties which enable efficient drug transport into different cell types with reduced side effects and cytotoxicity to other tissues.Materials and Methods: AuNPs were synthesized by adopting the Turkevich method to reduce tetra chloroauric (III) acid (HAuCl4) solution with sodium citrate. A factorial design of 24 was used to investigate the influence of temperature, stirring speed, and the volume of citrate and gold salt on the size of AuNPs synthesis. The produced chemical-AuNPs (CN-AuNPs) were characterized using ultraviolet-visible spectroscopy and dynamic light scattering (DLS) which was conjugated with polyethylene glycol (PEG) loaded with chloroquine diphosphate. The latter were characterized with transmission electron microscopy (TEM), Energy dispersive x-ray spectroscopy (EDS), selected area electron diffraction (SAED) patterns and Fourier transmission infrared spectroscopy. The antimalarial activities of the three formulations were tested on Plasmodium-infected mice. Moreover, the evaluation of curative potentials of the formulations was carried out via parasite counts. The anemic and pathological conditions of nano-encapsulation were investigated for their cytotoxicity level. Results: The CN-AuNPs show surface plasmon resonance absorption ranging from 526 to 529 nm with smaller particle size at the lower citrate volume. The TEM image of CN-AuNPs with polyethylene glycol (PEG) and CN-AuNPs-PEG encapsulated with chloroquine diphosphate revealed spherical shape with EDS showing the appearance of gold (Au) at 2.0, 2.1, and 9.9 KeV. The SAED also revealed that the AuNPs were crystalline in nature. The in vitro time-dependent encapsulation release showed an extension of time release, compared to CN-AuNPs-PEG with parasitemia clearance at the same level of cytotoxicity. Conclusion: Therefore, although improved activity of the CN-AuNPs-PEG encapsulating was achieved but its cytotoxicity still is a limitation.","PeriodicalId":18933,"journal":{"name":"Nanomedicine Journal","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49387941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods: In this work a facile and ultrasensitive colorimetric aptasensor was reported for detection of oxytetracycline (OTC) in water and milk samples employing OTC-short aptamer and gold nanoparticles (AuNPs). Results: In the presence of OTC, the interaction between OTC and its aptamer leads to the separation of OTC aptamer from the surface of AuNPs which is followed by the aggregation of AuNPs by salt, showing an evident color change from red to blue. On the contrary, in the absence of OTC, the attachment of aptamer on the surface of AuNPs can protect AuNPs against salt-induced aggregation with a wine-red color. The proposed aptasensor exhibits excellent sensitivity for detection of OTC with linear range between 20 to 2000 nM with limit of detection (LOD) as low as 10 nM. Furthermore, this strategy was applied to detect OTC in spiked milk samples and presented satisfying linear range from 25 to 1500 nM with the LOD of 20 nM.

The aim of the present study was to investigate the radioprotective effect of nanocurcumin on survival of mice under whole body X-ray irradiation. Materials and Methods: The Naval Medical Research Institute (NMRI) mice randomly assigned to separate groups and received nanocurcumin via oral gavage at different time points related to irradiation. The survival of mice was evaluated daily for 30 days post-irradiation and finally, the LD50/30 was calculated using Probit analysis. The 30-day survival curve was plotted using the Kaplan-Meier survival curve and the median survival of different subgroups was compared using log-rank test. The P-values less than 0.05 were considered significant. Results: Our results showed that the administration of oral nanocurcumin could effectively reduce the mortality rate in the irradiated mice. Five days pretreatment with nanocurcumin (4 mg/kg/day) induced maximum radioprotective effect. The LD50/30 was 7.18 Gray (Gy) (95% confidence interval [CI]: 6.59-7.77) and 8.78 Gy (95% CI: 8.14-9.50) for irradiation-only and the optimum nanocurcumin group (pre-irradiation group), respectively (dose reduction factor [DRF] = 1.22). Continued administration of nanocurcumin up to seven days post-irradiation resulted in no further radioprotection. Conclusions: The results obtained in this study confirmed the efficacy of nanocurcumin as a radioprotective agent against radiation-induced mortality in mice. The specific characteristics of nanocurcumin, such as non-toxicity, edibility, availability, make this phytochemical as a potential radioprotective agent in the radiotherapy setting and radiation accidents.
