Antibiotic susceptibility pattern and genetic typing for epidemiological purposes are of significant issues in Shigella infectious control. The aim of this study was to investigate the antibiotic susceptibility and genetic relationship among Shigella strains isolated from children with shigellosis at paediatric hospital in Ahvaz, south west of Iran. This study included all Shigella strains isolated from paediatric patients with diarrhea admitted to Abuzar pediatric hospitals in Ahvaz, during January-June 2015. Shigella isolates were identified using standard microbiological and serological methods. Shigella spp strains also were studied by antimicrobial susceptibility testing and Enterobacterial Repetitive Intergenic Consensus (ERIC) - PCR analysis. Total of 50 Shigella strains were isolated from children with dysentery diarrhea. In total, 31 (62%) were identified as Shigella flexneri, 16(32%) and 3 (6%) were Shigella sonnei and Shigella boydii respectively. High level resistance were detected against ampicillin, trimethoprim-sulfamethoxazole and cephalotine. All isolates were sensitive to ceftriaxone, imipenem gentamicin and amikacin. The results of ERIC-PCR data analysis showed 11 different types of Shigella with four closely-related patterns. S. flexneri was the predominant serogroup of Shigella spp. in children in the referral pediatric hospital in Ahvaz. Ampicillin and trimethoprim-sulfamethoxazole is no longer recommended for shigellosis empirical treatment and should be replaced by other antibiotics such as ceftriaxone or ciprofloxcacin. Diverse but genetically close strains of shigella were responsible for shigellosis in paediatric patients in Ahvaz, south west of Iran.","PeriodicalId":16663,"journal":{"name":"Journal of paramedical sciences","volume":"34 1","pages":"45-51"},"PeriodicalIF":0.0,"publicationDate":"2016-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88338292","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}

CTDIv depends on scan parameters such as mAs, kV, collimation, tube rotation time but is independent of patient’s size and shape. For the purpose of a good estimation of dose received by the patients, American Association of Physicists in Medicine (AAPM) published the conversion factors for both 16 and 32cm (head and body phantoms respectively); through this, users can extract conversion factors according to lateral (LAT) and/or anterior-posterior (AP) sizes and calculate real CTDIv. Since this procedure is time consuming, we designed MATLAB-based software to reduce such calculations. To design the software, GUI toolbar of MATLAB software was used. To test the software, scan parameters of two patients for head and pelvis scan were read from PACS and lateral (LAT) and anterior-posterior (AP) sizes were measured. Finally, SSDEs were calculated for two patients by the software. The software can be measured based on AP and/or LAT measures and/or in special cases (under the age of 18) through patients' age.","PeriodicalId":16663,"journal":{"name":"Journal of paramedical sciences","volume":"30 1","pages":"35-38"},"PeriodicalIF":0.0,"publicationDate":"2016-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88463090","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 studied method was performed on a dataset which contained data about 117 patients admitted to a hospital in Durham in 2009. Of all the studied patients, 66 patients were suffering from thromboembolic syndrome and 51 people were enrolled in the study as the control group. The gene expression level of 22277 was measured for all the samples and was entered into the model as the main variable. Due to the high number of variables, principal components analysis and auto-encoder neural network methods were used in order to reduce the dimension of data. The results showed that when using auto-encoder networks, the classification accuracy was 93.12. When using the PCA method to reduce the size of the data, the obtained accuracy was 78.26, and hence a significant difference in the accuracy of classification was observed. If auto-encoder network method is used, the sensitivity and specificity will be 92.58 and 93.68 and when PCA method is used, they will be 0.77 and 0.78 respectively.

For the efficacy evaluation of hydroquinone trapped in liposomal structure, there is a need to first separate liposome from the matrix surrounding it. There are various separation techniques; however, in this study, the three techniques of centrifuges with and without washing and dialysis were used. From among the laboratory techniques, an appropriate method is the one that offers responses with a high repeatability. The statistical calculations revealed that encapsulation efficacy with a direct method resulted from a separation via the techniques of dialysis and centrifuge without washing had the highest dispersion with SDs of 6.1 and 8.7, respectively, while the SD value in the technique of centrifuge with washing was 5.2. Through an indirect method, hydroquinone encapsulation efficacy showed the best repeatability with SD values of 2.8 and 2.1 by using the two techniques of centrifuge and centrifuge filtration, respectively. It seems that the treatments leading to the dilution of hydroquinone formulation would result in hydroquinone leakage and a reduction of encapsulation efficacy. It seems that measurement of hydroquinone encapsulation efficacy with an indirect method is a better choice; therefore,  a centrifuge technique was utilized to report the mentioned efficacy at a speed of 45000 rcf and duration of 30 min due to having a reasonable price and ease of access.","PeriodicalId":16663,"journal":{"name":"Journal of paramedical sciences","volume":"626 1","pages":"23-28"},"PeriodicalIF":0.0,"publicationDate":"2016-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74722505","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}

Some researchers evaluate the changes in serum or CSF level of this antibody during immunomodulatory therapy; the results are different and the relation between the changes in this antibody and response to treatment is poorly investigated. The objective of this study was to assess the relation between the changes in serum level of anti-MBP and clinical remission in patients during treatment with fingolimod. 37 MS patients that were non responder to interferon and glatiramer acetate and were candidates to receive fingolimod were nominated for this study.  In this study, the serum level of anti-MBP was evaluated before and after 3 and 6 months of therapy and clinical remission was assessed by changes in Expanded Disability Status Scale (EDSS) scores. The result of this study showed that MS patients, after treatment with interferon, have lower serum anti-MBP level than healthy control group and this difference is statistically significant (p =0.03).  The present study demonstrated that the serum anti-MBP level in MS patient during 6 months of treatment with fingolimod significantly decreased (p<0.001).

In the present study, AST activity was estimated in the extracts of untreated parasite (hydatid cyst protoscolices) and treated samples by MBZ (100 µg final concentration). Samples’ protein quantity and quality were detected by Bradford and sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) methods respectively. For the purpose of determining the significant difference between the two independent samples, t-test was conducted. The values of the assayed AST specific activities of treated and untreated parasite samples were measured as 0.18 and 1.53U/ml/mg protein respectively. The difference between AST activities mean values of the two groups proved to be significant (P<0.05). SDS-PAGE demonstrated protein band of 50 kDa for AST enzyme.

Research in gynecological field relies heavily on repeated measure designs. Repeated measure studies are helpful in understanding how factors of interest change over time. Our goal is to apply statistical methods which are appropriate for analyzing repeated measure data such as gynecological data. Three statistical methods were performed by data collection from 100 patients with menorrhagia. One-hundred patients were randomly assigned to two groups, i.e. intervention group (Urtica Dioica and mefenamic acid) and control group (placebo and mefenamic acid) with an equal size of 50. In this study, generalized estimating equations (GEE) and mixed effects models (MEM) were used for analyzing menorrhagia data to determine the effect of hydroalcoholic extract of Urtica Dioica on Menorrhagia. Finally, these methods are compared to the conventional repeated measures ANOVA (RM-ANOVA). Based on the results, the three methods are found to be similar in terms of statistical estimation, the amount of bleeding before and after treatment between and within groups was compared. Results showed the average amount of bleeding was reduced significantly (P˂0/001). The average menorrhagia score in the third month (second cycles after intervention) were 91.38(71.432) and 149.40(127.823) in Urtica Dioica and control groups, respectively. The difference between the two groups was statistically significant (p =0.036). Because their advantages, GEE and MEM should be strongly considered for the analysis of repeated measure data. In particular, GEE should be utilized to explore overall average effects. When in addition to overall average effects, subject-specific effects are of primary interest, MEM should be utilized. With respect to these methods, it seems the extract of Urtica Dioica can be effective in reducing the amount of menstrual bleeding in women of reproductive age with Menorrhagia.","PeriodicalId":16663,"journal":{"name":"Journal of paramedical sciences","volume":"20 1","pages":"32-40"},"PeriodicalIF":0.0,"publicationDate":"2016-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73878584","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}
