Abstract

Background : Salmonella is a short rod shape, gram-negative, non-encapsulated, aerobic and anaerobic options that cause food poisoning in humans. Raw food of animal origin, particularly meat and eggs of birds have important role in the transfer of this disease. Since duck and turkey eggs are very important in the transmission of Salmonellosis and consuming of local and non-industrial eggs of ducks and turkeys in this area is common, the present study was performed to clarify the prevalence of salmonella contamination. Materials and Methods: In the present study, 300 native duck and turkey eggs were collected and transferred to the lab. In laboratory after sampling from surface of the eggs shell were disinfected with 80% ethanol and contents of 5 duck and turkey eggs, sparately mixed in special dishes. After 24 hr incubation at 37°C with a swab in selenite - F broth were inoculated. Samples were transferred to Salmonella - Shigella agar from selenite-f environment. After incubation in 37°C, colonies suspected to Salmonella were evaluated. Suspicious colonies in the TSI and lysine decarboxylase environments were inoculated. And bacteria that had reactions related to Salmonella, were studied by PCR with specific primers for Salmonella and serotypes of Salmonella Enteritidis and Salmonella Typhimurium. Results: A total of 300 eggs of ducks and turkeys ,7 cases (2.3%) were contaminated with Salmonella, and from 7 unclean egg s shell , 1 case of turkey egg shell (0.66%) was infected with Salmonella Typhimurium. And 6 duck eggs shell (4%) were infected, that all of the serotypes were Salmonella Typhimurium. Conclusion: Regarding the present study, and other researches, it can be concluded that the Salmonella infection in the duck and turkey eggs were less than poultry eggs and it seems that vertical transmission of Salmonella in the turkeys and ducks was less than poultry.

Abstract

Background: Today, with the increasing pressures of life and, consequently, increasing stress, mental health is endangered. In this regard, the style of personality and mental toughness is noted that is effects on mental health. The aim of this study was to investigate the predictive role of psychological toughness in mental health both directly and indirectly through the mediation of personality dimensions.
Material and Methods: In a cross sectional study 273 students at Allameh Tabataba’i University Campus in the 2014-2015 school year with cluster sampling were selected. Variables assessments were done by the General Health Questionnaire (GHQ), Personality Assessment Inventory short form (NEO) and Kalaf mental toughness questionnaires. Data were analyzed by the path analysis modeling method and using SPSS-21 and LISREL software.
Result: Chi-square theoretical model of this study was equal to 2.47; the measure is insignificantly according to significant level of 0.116 which at first glance may suggest that the model is appropriate and representative of the society. Other fitness indicators, including indicators of GFI=0.98, NFI=0.97, CFI=0.97, AGFI=0.93 & RMSEA=0.06 which is accepted according to the model offered.
Commitment, live control and self confidence in interpersonal relation indirectly predicted mental health (p<0.05). Excitation control and self confidence in interpersonal relation directly predicted mental health (p<0.05).
Conclusion: Some features of mental toughness regardless of the effect of the character can cause mental health that According to the findings, emotional control and self-confidence are more important. It is suggested that these items be taught to improve mental health.

Abstract

Background: Alzheimer's disease is a multi-factorial disorder. The genes involved in Alzheimer's disease act as risk factors. The aim of this study was to investigate the APOE gene polymorphism in patients with Alzheimer's disease in Iran.
Materials and Methods: In this analytical-descriptive study, 50 patients with Alzheimer's were investigated. Polymorphism of the APOE gene was investigated in healthy subjects and patients with Alzheimer's using Tetra Arms PCR.
Results: The frequency of the 4ε /4ε genotype and ε4 allele was significantly higher in patients with Alzheimer's compared to healthy subjects (38/4% and57/4% versus 3/8% and 28/8%, respectively) (P≥0.009).
Conclusion: In polymorphism of the APOE gene, the 4ε /4ε genotype, and the ε4 allele, are risk factors for Alzheimer's disease in the Iranian population.

Abstract

Background: Studies have demonstrated the healing effects of Viscum album on sites of inflammation and injury. The aim of this study was to investigate the effects of Viscum album aqueous, alcoholic and acetone extracts on fibroblast cell proliferation in cell culture.
Materials and Methods: Aqueous, alcoholic and acetone extracts of Viscum album were prepared.  Fibroblast cells were obtained from the Pasteur Institute (Tehran, Iran) and kept under standard conditions.  The cells were divided into control and test groups, and the groups were exposed to 1, 0.1, 0.01 and 0.001 mg/ml of aqueous, alcoholic and acetone extracts of Viscum album. The effect of the extracts on fibroblast cell proliferation was evaluated using MTT assay. The data were analyzed using ANOVA.
Results: The results indicated that fibroblast cell proliferation decreased significantly compared with the control group (P<0.001) when exposed to 1mg/ml of aqueous and ethanol extracts of Viscum album. However, fibroblast cell proliferation increased significantly compared with the control group (P<0.001) when exposed to 1mg/ml of acetone extracts of Viscum album
Extract concentration of 0.1, 0.01 and 0.001 mg/ml had no significant effect on L929 cell proliferation.
Conclusion: A high appropriate dose of acetone extract of Viscum album has stimulatory effects on L929 cell proliferation in cell culture. Therefore, it could play a significant role in the healing of sites of inflammation and injury
