[In vitro evaluation of Candida albicans adherence and growth on GC and acropars soft liners]

Adherence and growth of Candida albicanson denture soft lining materials can result in clinical problems, and deteriorations of the materials. Prevalence of denture stomatitis in association with candida albicans has been reported to range between 11%-67%. The aim of this study was to evaluate the adherence and growth of Candida albicanson two type of denture soft liners [GC and Acropars] and comparison to control group [Acropars acryl]. Twenty-two specimens of each soft lining material and 10 acrylic specimens [polished and not polished] were made and incubated in a suspension of Candida albicans. After rinsing, the specimens were stained with acridine orange and examined under fluorescent microscope. For statistical analysis One-way ANOVA and Post Hoc, TukeyHSD tests were used. The highest and the least adhesion and growth were found in the not polished and the polished groups respectively. Also, adherence and growth on Acropars soft liner was significantly more than GC soft liner [p<0.05]. Significant difference was found between polished and not polished acryl [p<0.05]. According to results, precise attention in selection of correct material with the lowest side effects and it's production steps seems mandatory

[Transtheoretical model-based [TTM] interventions to improve physical activities in elderly men]

Understanding and influencing the determinants of physical activity is an important public health challenge. This study examines the application of key constructs of the transtheoretical model to physical activity behaviors for aged people. This study is a field trial with census sampling. Sixty healthy adult men at Kahrizak nursing home in 1386 completed a questionnaire including demographics and self-reported levels of physical activity, constructed from the Transtheoretical Model [TTM], before and after two months of intervention. The interventional program included tailored counseling and focus group. The data were then analyzed with T test, X[2], pair T test and Wilcoxon, using SPSS software. Statistical analysis showed a significant difference for the effect of health education program on increasing stage of change, self-efficacy, decisional balance and physical activity behavior in elderly people [p<0.0001]. Educational physical activity interventions can result in increased physical activity, thus, health education program based on TTM has had positive effect on promotion physical activity behavior. It can be recommended that health education be used on educational models
