    A new noncentrosymmetric Cd(II) complex with thetripodal amine tris(2-aminoethyl)amine, CdCl2[N(C2H6N)3]2, has been prepared and characterized by single crystal X-ray diffraction, solid state NMR and IR spectroscopies. In the complex, the Cd(II) ion is surrounded by sevennitrogen atoms. The organic molecule acts as both a tri-and a tetradentate ligand. The cationic complexes are linked to each other forming layers parallel to the (a, b)plan. The Cl- counter ions occupy the cavities created inside these layers. The 13C CP-MAS NMR spectra are in agreement with the X-ray structure. DFT calculations allow the attribution of the carbon peaks to the differentatoms.The vibrational absorption bands were identified by infrared spectroscopy and DFT calculations allowed their attributions

    ABSTRACTObjectives: This study was planned to evaluate the prevalence of Staphylococcus aureus in cases of atopic dermatitis (AD) in Najaf city.A total of 100 skin swabs were obtained from the effected skin areas of patients who were attending to AL-Sader Teaching Hospital in AL-Najaf city during the period from May to October 2014.with (AD), along with 50 skin swabs that were obtained from a comparable skin area of 50 persons who were regarded as a control group and comparable in ages and genders with the patient group. All the skin swabs (patients and control) were then immediately streaked on the surface of selective media for isolation and identification of S. aureus preliminary. Then the suspected isolates were confirmed by specific biochemical and enzymatic confirmative tests. The incidence of Staphylococcal isolates was detected according to the age, gender, duration, severity and also according to the family history.Results: From the 100 swab samples of patients, there were 54/100 (54%) showed positive isolation of S. aureus, while only 10/50 (20%) swab samples of the control group showed positive S. aureus isolation. The difference between the two groups was statistically significant (P˂ 0.05). The prevalence of moderate AD cases was higher than that of mild and severe (55.56%> 20.37%˂ 24.07%) respectively. Thirty seven patients (68.52%) were categorized with family history inheritance of AD (Results were statistically significant (P˂ 0.05), with male to female ratio was 1.25:1. Seventeen patients (31.5%) were categorized as acute AD, while 37 patients (68.5%) were diagnosed as chronic.Conclusions: Staphylococcus aureus infection is positively correlated with AD cases, and genetic factors may play an important role in increasing the frequency of AD cases.Recommendations: We recommended to use genetic studies for the monitoring of Staphylococcus aureus virulence factors correlated with AD.Key words: Staphylococcus aureus, atopic dermatitis, SCORAD index

    Background: Expatriates represent >80% of Qatar’s population, mostly arriving from countries in Africa and Asia that are endemic with many diseases. This increases the risk for introducing new pathogens into the country and provides a platform for maintenance of endemic pathogen circulation. Here, we report on the incidence and epidemiological characteristics of hepatitis B in Qatar between 2010 and 2014. Methods: We performed a retrospective epidemiological data analysis using the data available at the surveillance system of the Ministry of Public Health (MOPH) in Qatar. Data were collected from distinctive public and private incorporates around the nation. Reported cases of hepatitis B patients represent those who met the stringent case definition as per World Health Organization (WHO) and Centers for Disease Control and Prevention (CDC) guidelines and eventually reported to MOPH. Results: The annual incidence rates of hepatitis B cases were 30.0, 34.2, 30.5, 39.4, and 19.8 per 100,000 population in 2010, 2011, 2012, 2013, and 2014, respectively. There was no specific trend or seasonality for the reported cases. The incidence rates were higher in females compared to males between 2010 and 2012, but similar in 2013 and 2014. The highest incidence rates were reported among individuals between 25 and 34 years of age. No cases were reported in children younger than five years in 2013 and 2014. Rates of hepatitis B cases declined dramatically in 2014, in both Qataris and non-Qataris, as compared to the previous years. Conclusion: Our results indicate a dramatic decline of hepatitis B cases in Qatar but mandate improved surveillance and vaccination efforts in expatriates in the nation. View Full-TextMOP

    The aim of the study is to know the effect of the hepatitis B virus on humans, how the virus is transmitted, what is the method of preventing it, and what treatment is used to alleviate the severity of the disease. The questionnaire was designed via the Google Drive application and distributed via the social networking application (WhatsApp), with complete transparency to the population targeted by the research. The city of Mecca, from the age of (25-55 years), where 550 questionnaires were distributed via social media application groups (WhatsApp) according to available conditions (distancing), and answers to 525 questionnaires were obtained
