This study investigates the application of copolymer nanocapsule (PEG-PLA) systems with controlled release specificity for a recombinant protective antigen and lethal factor of Bacillus anthracis to provide a vaccine candidate. Material & Methods: In this experimental study, the dual solvent evaporation emulsion method was used to produce nanocapsules. Moreover, zeta potential and size of nanoparticles, loading efficiency of nanoparticles, recombinant protein release pattern, the probable effect of PLA-PEG nanoparticle production on the shelf life of recombinant proteins were investigated in this study. Mice were used as test and control samples for antibody production and immune response evaluation. (Ethic code: 9727250) Findings: The results of this study showed that mixed proteins (LFD1+PAD4) loaded on PEG-PLA block copolymer had an average size of 109 nm, the zeta potential of -27.7 mV, and PDI=0.394. In this study, it was shown that the release of these antigens was carried out in two stages of rapid and slow release. The release of the proteins was estimated at about 20% on the first day and 78% on the 49th day. The titers of antibodies produced in the serum of the mouse groups against these antigens at defined intervals were significantly different from each other. Discussion & Conclusion: The results of this study suggest the application of PEG-PLA block copolymer nanocapsules containing mixed recombinant proteins of protective antigen and lethal factor of Bacillus anthracis. Due to less degradation and more protection of antigen activity in nanoparticles, compared to traditional methods, as well as fewer repeat injections, higher specificity, reduced side effects, lower cost, and slower release rate, the use of nanoparticles is a good option to replace traditional methods.","PeriodicalId":16041,"journal":{"name":"journal of ilam university of medical sciences","volume":"90 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74978481","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}

The use of carbon nanostructures has attracted much attention due to their unique properties, such as crossing cell membranes, for cancer diagnosis and other medical applications. This study aimed to investigate and assess the toxicity of the modified graphene oxide (GO) with isatin-3-semicarbazone (ISA) in order to treat retinoblastoma. Material & Methods: This study utilized ISA to modify the GO. Subsequently, the modified GO-ISA was characterized by different techniques, such as Fourier transform infrared spectrometry, Scanning Electron Microscope, and Thermal Gravimetric Analysis. The cell toxicity of samples was assessed by MTT assay for two types of cells of retinoblastoma (Y79) and adipose-derived stem cells (ADSC) after 24 h at different concentrations. Data were analyzed in SPSS software using one-way analysis of variance (ANOVA). A p-value less than 0.05 was considered statistically significant. Findings: The results showed that in the concentration range of 10-50 μL, GO-ISA decreased significantly (P<0.01) the conservation percentage of retinoblastoma cells from 73.98% to 27.48%, while these values for ADSC decreased from 78.16% to 50.11% (P<0.01). In addition, GO-ISA at 30 μL resulted in a significant increase (P<0.01) in the cell toxicity of the retinoblastoma (26%), compared to GO. Discussion & Conclusion: GO-ISA increases the toxicity of the retinoblastoma cells, compared to GO which was significant at 30 μL. Therefore, this modification of the surface can be useful in future applications. With this modification of the surface, the active sites are provided for the biological and pharmacogenetic reactions in future.","PeriodicalId":16041,"journal":{"name":"journal of ilam university of medical sciences","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80443074","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}

In the present study, the toxicity and antimicrobial effects of two natural monomeric peptides (S3 and S∆3) were compared with S3-S∆3 hybrids and S3 tetramers. Material & Methods: Protein hybrids (S∆3S3-2mer-GS) S3-S∆3 and tetramer protein S3 (S3-4mer-GS) were expressed in E. coli . BL21 (DE3). Following that, the presence of mutant peptides was confirmed, and their antimicrobial activity was compared and evaluated with S3 and S∆3 monomers. Finally, the toxicity of tetramer and hybrid made on the MDA-MB-231 cell line was evaluated and compared. Findings: The toxicity of the hybrid was slightly increased, compared to the tetramer for eukaryotic cells; however, this increase was negligible at the active concentration of this protein. Cell survival for hybrids was lower for S3 and SΔ3; nonetheless, cell survival for each sequence decreased with increasing time. Furthermore, the inhibition of hybrid microbial growth was improved and compared with tetramer and S3-SΔ3. It was found that an increase in the positive charge of the hybrid protein did not have a toxic effect on the host bacteria. Discussion & Conclusion: Due to the appropriate expression and increased antimicrobial activity and negligible cytotoxicity, the hybrid peptide S3-S∆3 and tetramer S3 can be considered an effective production strategy to obtain AMPs.","PeriodicalId":16041,"journal":{"name":"journal of ilam university of medical sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82990288","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}

Therefore, this study aimed to assess the prevalence of anabolic steroid misuse, as well as the awareness level and attitude toward its negative effects on male bodybuilder athletes in Kermanshah, Iran. Material & Methods: This descriptive cross-sectional study was conducted in 2019. The statistical population included all male bodybuilder athletes in Kermanshah, Iran. The data were collected using a 25item self-reported anabolic-androgenic steroids questionnaire (demographic characteristics: n=7, awareness level: n=9, attitudes: n=5, and the prevalence of abuse: n=5) which was distributed using the multistage clustering method among 250 male bodybuilder athletes in Kermanshah, Iran. The obtained data were analyzed in SPSS software (version 22) through descriptive statistics (frequency, percentage, mean±SD) and inferential statistics (Pearson correlation coefficient). A p-value less than 0.05 was considered statistically significant. Findings: The results indicated that anabolic-androgenic steroid use was prevalent in 65.2% of the subjects. The most common cause was to increase muscle mass and strength. According to the results of this study, the prevalence of androgenic-androgenic steroid use showed a significant inverse relationship with attitude (r=-0.78; P=0.021), awareness (r=-0.73; P=0.032), an education level (r=-0.79; P=0.022).
