This study was conducted to determine the contamination of E. coli and Salmonella for different types of foods in Chittagong city area. In case of laboratory examination, almost half (49.58%) of the samples were contaminated where 28.75% positive for E. coli. and 20.83% for Salmonella. The positive cases for type A sample was 20 out of 96 constituting 20.83% whereas the positive cases for type B sample was 49 out of 144 constituting 34.03% for E. coli. The positive cases of type A sample was 15 out of 96 making up 15.63% and for type B sample was 35 out of 144 making up 24.31% for Salmonella.A chi-square (?2) test was used to examine the equality of observed proportions for E. coli and Salmonella of each item of both types of food where significant difference among the observed proportion for E. coli (p-value<0.01) and Salmonella (p-value=0.032) for different items of A type and for E. coli (p-value<0.01) for different items of B type were observed and an odds ratio (OR) was measured for association between exposure and outcome where the probability of contaminated by E. coli of type B food is higher than contaminated of type A food (OR= 1.96 and CI:1.07-3.58). The probability of contaminated by Salmonella of type B food was higher than type A food (OR= 1.73 and CI: 0.89-3.39).The comparatively high bacteria in type B samples indicated contamination from water, practice of inadequate hygienic measures, mishandling, improper storage, inadequate cooking and above all unhygienic condition of the retail shops.DOI: http://dx.doi.org/10.3329/jesnr.v6i1.22034 J.

The study was conducted to determine the contamination of Salmonella for different types of street foods in different places of Chittagong city area. A total of 76 shops from where 120 food samples of ten types were collected. Microbiological examination of Salmonella was done after dividing the foods into two categories of dry and wet foods where overall about 28% samples were positive. In case of wet food, salad shows the highest contamination of 58% flowed by water, chicken raw meat and raw milk makes up 50%, 42% and 33% respectively. For wet food, vegetable role and egg chop show the same 25% contamination where kabab and beef stick were not contaminated. A chi-square (χ2) test was used to examine the equality of observed proportions for each item of food where significant difference among the observed proportion for Salmonella (Chi-square = 82.67; p-value<0.01) for different items of food were observed and an odds ratio (OR) was measured of association between an exposure and an outcome where the probability of contamination of Salmonella in dry food was lower than wet food (OR=0.17 and CI: 0.07 to 0.44). The comparatively high bacteria in wet samples indicated contamination from water, practice of inadequate hygienic measures, mishandling, improper storage, inadequate cooking and above all unhygienic condition of the retail shops.

Descriptive Theories

Long since Translation Studies emerged as a nascent academic discipline, it has seen a considerable number of descriptive theories and models, among which, Catford’s (1965) translation ‘shift’ approach has garnered particular attention within the realm of translational comparative studies. Quranic texts have constantly been the center of attention, as the Quran has established itself as the most famous and sublime text in Arabic. As such, the present comparative study aimed at investigating the frequencies of different types of translation shifts occurring in translations form Arabic into English drawing on Catford’s (1956) shift typology. To this end, seven translations of the first thirty verses of the Chapter ‘Yusuf’ rendered by Sarwar, Arberry, Irring, Pickthall, Saffarzade, Shakir and Yusef Ali were selected to be studied. First, each element was compared for any probable shift(s). Then, the Chi-square procedure was applied in order to establish the existence of any statistically significant differences in shift frequencies. The results indicated that there was a statistically significant difference between five types of shifts. The results also revealed that the most frequent translation shifts from Arabic into Persian were Unit shifts and Level shifts with a mean of 83 and 49 respectively.

Introduction: Pain during the injection of anesthetic agents may be distressing and can reduce the acceptability of an otherwise useful agent such as propofol during daycare surgeries. Lidocaine and ketamine both are used as pre-treatment to decrease propofol induced pain. This study aims to compare the effectiveness of ketamine injection to decrease propofol-induced pain in comparison to lidocaine injection. Methodology: This is a prospective cross-sectional comparative study. Eighty-nine cases were divided into two groups where group K received ketamine 2 ml (0.2 mg/kg) whereas group L received lidocaine 2% 2ml (0.5 mg/kg) after venous occlusion with rubber tourniquet. One-fourth dose of propofol was injected 1 min after release of tourniquet and pain accessed at 0, 1, and 2 minutes of propofol injection with a verbal response and behavioral signs. Chi-square test and paired T-test were used and a p-value less than 0.05 was considered significant. Result: Regarding hemodynamic, oxygenation, and adverse effects there was no significant difference. Immediately after propofol injection, only 1 patient of the ketamine group had mild pain (2.22%) while 12 patients from the lignocaine group had mild pain (27.27%) with a p-value of 0.009. Also after 2 minutes of propofol injection, only 12 cases had mild pain i.e. 13.48% (1 from ketamine group i.e. 2.22% and 11 from lidocaine group i.e. 25%) with p-value of 0.002. Conclusion: Our study helps prove low-dose ketamine is more effective in reducing the incidence and severity of pain on injection of propofol in comparison to Lidocaine with better hemodynamic stability.

Diarrhea is defecation with a frequency more often than usual (three times or more) a day (10 mL/kg/day) with a soft or liquid consistency, even in the form of water alone. Pathogenic bacteria, such as Escherichia coli, Salmonella typhimurium, and Shigella sp., play a role in many cases, to which antibiotics are prescribed as the first-line therapy. However, since antibiotic resistance cases are often found, preventive therapies are needed, such as consuming yogurt, which is produced through a fermentation process by lactic acid bacteria (LAB). This research aimed to determine the activity of lactic acid bacteria (Liactobacillus bulgaricus and Streptococcus thermophilus) in yogurt in inhibiting the growth of the pathogenic bacteria E. coli, S. typhimurium, and Shigella sp. The research applied in vitro with the liquid dilution test method and the true experimental design research method with post-test-only and control group design. The design was used to see the inhibitory effect of yogurt LAB on the growth of E. coli, S. typhimurium, and Shigell sp. to compare the effect of several different yogurt concentrations, namely 20%, 40%, 60%, and 80%. The results of the Least Significance Different analysis showed that there was a significant difference between yogurt with a concentration of 0% and that with various concentrations in inhibiting the growth of E. coli, S. typhimurium, and Shigella sp. with a p-value of &lt;0.05. Whereas, there was no significant difference in the various concentrations of yogurt in inhibiting the growth of the three kinds of bacteria with a p-value of &gt; 0.05.<p class="Default" align="center"> </p>

Background: The SSRIs being used as 1st line therapy in treatment of depression have delayed therapeutic effect which makes the patient vulnerable to an increased risk of suicide and decreased adherence to the treatment and will prematurely discontinue the therapy. The present study was conducted to evaluate if low dose mirtazapine-escitalopram combination therapy has any add on benefit over monotherapy with escitalopram.Methods: In a single-centered, comparative study involving patients with depression attending the out-patient after screening and exclusion, 60 eligible patients were randomly assigned to receive tablet mirtazapine 7.5 mg plus tablet escitalopram 10 mg intervention or tablet escitalopram 10 mg plus placebo intervention in a double-blind 6-week treatment phase. The primary outcome measure was the change in the 17-item Hamilton Depression Rating Scale (HDRS) and Montgomery-Asberg Depression Rating Scale (MADRS) score from baseline. Participants were evaluated at baseline, 1st, 2nd,4th and 6th week. Results were analyzed using Chi-Square test for adverse effects and independent t-test analysis for efficacy parameter.Results: In the analysis of results at 6th week the numbers of patients achieved remission in mirtazapine group are more with a p-value of 0.018 which is significant and the numbers of responders in mirtazapine group are also more which is statistically significant on chi-square test. There is no significant difference was observed between the two groups with reference to occurrence of adverse effect.Conclusions: Adding low dose mirtazapine has an added benefit in terms of efficacy and getting remission early with more number of responders in the treatment of major depression.

Objectives: Febrile seizures (FS) are the most common type of seizures and typically transpire in children with ages from 6 to 60 months. This study was planned to find out major clinical risk factors for seizures in febrile children who were aged 6 to 60 months. A total of 100 febrile children aged 6 to 60. Study Design: Analytical Study. Setting: Department of Neurology, Children’s Hospital and the Institute of Child Health, Multan. Period: From 1st April 2018 to 31st December 2018. Material & Methods: Group A had 40 children with febrile seizures while group B had 60 febrile children but without seizures. Demographic features along with family history of (H/O) epilepsy as well as family history of febrile seizure, types of seizure and infection diseases were noted and analyzed using SPSS version 20. Odds ratio was calculated for various risk factors. Chi square test was applied and P value < 0.05 was considered as significant. Results: Out of a total of 100 children, there were 54 (54.0%) male and 46 (46.0%) female. There was no statistical difference in terms of gender between the two groups (p value = 0.566). Overall, mean age of the children was 26.02 months with standard deviation of 13.4 months. There were 28 (70.0%) children who reported with simple seizures while complex seizures were found in 12 (30.0%) cases. Statistically significant difference (p value = 0.001) was seen in terms of types of infections between the two study groups. When risk of seizures for various risk factors was calculated, family H/O FS, family H/O epilepsy, and upper RTI were as 14, 7 and 3 times respectively and turned out to be the major risk factors for seizures in febrile children. Conclusions: Family H/O FS, family H/O epilepsy and upper RTIs are the major risk factors related with seizures in febrile children. Measures to prevent these risk factors can decrease the burden of FS in our population.
