    Microencapsulation of probiotic Saccharomyces cerevisiae var: Boulardii with different wall materials by spray drying
    (Academic Press, 2015) Arslan S.; Erbas M.; Tontul I.; Topuz A.
    Saccharomyces cerevisiae var. boulardii have probiotic properties which are beneficial for human health. It has been commonly used as a drug against gastrointestinal disorders. Saccharomyces boulardii has been used in some food formulations in recent years, due to its probiotic properties. However, it is not sufficiently stable for food processing and gastrointestinal systems. In this study, S.boulardii was microencapsulated with six different wall materials (gelatin, whey protein concentrate, modified starch, maltodextrin, pea protein isolate and gum Arabic) and spray dried using two different inlet temperatures (80°C and 125°C). The highest product yield was obtained with whey protein concentrate and gum Arabic. Survivability of the S.boulardii did not change with the wall materials, but it increased at the lower drying temperature. Survivability in a simulated gastric solution test at different pH levels and durations showed that gum Arabic is the best wall material followed by gelatin and pea protein. The microcapsules produced at the higher drying temperature (125°C) showed, a higher resistance to the gastric solution than those of the lower drying temperature (80°C). In addition, survivability was decreased by increasing exposure time to the simulated gastric solution. © 2015 Elsevier Ltd.

    The relationship between dental fear and sociodemographic variables [Sosyodemografik De?işkenlerle Dental Anksiyete Arasındaki İlişki]
    (AVES, 2011) Arslan S.; Ertaş E.T.; Ülker M.
    Purpose: The aim of the study was to investigate the effects of age, gender and educational level on the dental anxiety of patients admitted to the Department of Restorative Dentistry and Endodontics at Erciyes Universitys Faculty of Dentistry. Patients and Methods: In the study, 324 patients were asked to complete a questionnaire. The survey consisted of two sections. The first section requested participants sociodemographic information such as including age, gender and educational level. The second section consisted of the Modified Dental Anxiety Scale (MDAS). Results: No correlation was found between age and MDAS (r= -0.011, p=0.844). Females tend to be more anxious than males (p< 0.001). The results showed that educational level had no significant effect on dental anxiety (p=0.837). Conclusions: In this study, it was observed that dental anxiety was not affected by age or education level, and that the dental anxiety levels of females were higher than males.
