Comparison between phenotype and molecular resistance characteristic in Staphylococcus epidermidis isolates from wound infections in Al-Basrah province, Iraq

Background:Staphylococcus epidermidis is considered the upper respiratory tract's human skin flora and mucosal membrane and displays low pathogenic capacity in healthy individuals. Drug-resistant strains can be identified as a natural result of the microflora through antibiotic therapy and are a possible cause of pathogenic strain resistance genes. Methods:Culture, biochemical analysis and Vitek®2 Utilizing for identified the One hundred and fifty swab sample was collected from different wounds infected. S. epidermidis strain's ability to resist antibiotics was tested using a disk diffusion method. Result of antibiotic sensitivity test was confirmed and supported by Vitek®2 system. Also, the PCR antibiotic resistance gene was detected. Results: Out of 150 swab samples, twelve were positive for S. epidermidis.. Disc method was shown the 75%,66.7%,83.3% and 58.3% harboured highest prevalence of antimicrobial resistance against penicillin, oxacillin, cefoxitin and erythromycin respectively.While the moderate prevalence 50.7%,41.7% and 33.3% of resistance against tetracycline,clandomycin and ciprofloxacin respectively. Furthermore, lowest incidence was shown the 25% for both of resistance against rifampin, and gentamycin. The Vitek®2 system was confirmed and support antibiotic sensitivity test. A most frequently found antibiotic resistance genes amongst S. epidermidis strains, according to the findings, were mecA (91.7%), blaZ (91.7) , ermA (16.7%),ermB (25%),ermC (25%), tetM (25%), tetK (33.3 %) and aacA-aphD (41.7%) respectively. All S. epidermidis strain doesn't have ,vanA and vanB antibiotic resistance gene. Conclusion:Frequency of resistance to antibiotic should be detected more than one method , and used the Vitek®2 system detected the antibiotic resistance gave better support for result.

Effect of diet control and exercise on the lipid profile of obese men

Background: Obesity is a major health problem which might contribute to many other problems such as heart disease and hypertension as well as diabetes due to abnormal lipid profile. The main objective of the current study was to compare the effectiveness of diet or treadmill exercise on normalizing the lipid profile of obese subjects.Methods: Forty women complaining from obesity was enrolled in this study and was randomly divided into 4 groups: control group: 10 obese women which don’t receive any thing, diet group: 10 obese women which received polysaturated fatty acid diet, exercise group: 10 obese women which received treadmill exercise for 30 minutes and lastly diet/exercise group: 10 obese women which received both diet and exercise. Measurement of weight, body mass index, and lipid profile for all groups was measured before and after 60 days of treatment intervention. Results: Diet and exercise should have a highly significant decrease of weight and body mass index and normalizing the lipid profile (p≤0.05) under the current situation used in this study.Conclusions: It was concluded that the combination of diet and exercise was highly effective in normalizing the lipid profile and overcoming obesity.

Local and regional earthquake magnitude calibration of Tabuk analog sub-network, Northwest of Saudi Arabia

AbstractThe Seismic Studies Center at the King Saud University has established a seismic sub-network at the NW of Saudi Arabia in 1985. It was named the Tabuk sub-network, after the city of Tabuk in the area. A data set of 194 earthquakes were selected and their corresponding ML values calculated by the nearest seismic network (ISSN). 137 observations of these earthquakes were gathered from AYN station, 82 observations from BADA station, 162 observations from HQL station and 65 observations from SRFA station. Four steps analytical procedure were carried out as follows: (a) Compilation of data for multi-linear regression, (b) linear regression of the common logarithm of the base 10 of the signal duration (τ), (c) smoothing of the data, and (d) multiple linear regressions of the main variables. The following range of values was incorporated for empirical contestant’s a1, a2, a3. a1 vary from −3.05 to −1.68, a2 vary from 2.17 to 2.61 and a3 (which is the epicentral distance correction) vary from 0.003 to 0.004, while the standard deviations vary from 0.17 to 0.22 and the correlation coefficients vary from 0.943 to 0.970. The empirical constants are determined by stepwise multiple linear regression. The local magnitude was assigned as the dependent variable, while the common logarithm of the signal duration, epicentral distance, and the focal depth were assigned as the independent variables. The reasons of using MD in this sub-network are as follows: (a) it does not require any amplitude calibration; (b) it is not affected by instrument saturation; (c) the often-negligible distance-dependence makes the method applicable and (d) this method has an extensive application, especially in micro-earthquake surveys

Sustainable Warehouse Features: A Systematic Literature Review

Development in the field of IT and competition in the market forces companies to increase their market share and revenue. To satisfy this goal, companies can apply and adopt plans that may lead to making the supply chain (SC) lengthy and too rigid to control/monitor. The longer the SC the more it can be disrupted by expected and unexpected events (e.g., Digital security incidents, climate). For that purpose, the SC must be built in a way to respond fast to disruptive events in an effective way and to bounce back to its original state to be considered a resilient SC, which gives a competitive advantage to the companies. To achieve SC resilience, several studies have discussed enablers. Some of these studies, focused on increasing velocity through the SC, others argued that high adaptability leads to SC resilience, and others mentioned information sharing as a key to achieving SC resilience. In addition, applying technology in the SC processes can add strength. As such, the Internet of Things can support/enhance the level of Velocity, Adaptability, and Information sharing, which leads to enhancing SC resilience. This research explores the opportunities that IoT presents to enhance resilience enablers and boost SC resilience
