    The purpose of this paper is to explore practical issues in developing and implementing a culturally tailored Internet Cancer Support Group for a group of ethnic minority cancer patients—Asian American cancer patients. Throughout the research process of the original study testing the Internet cancer support group, research team made written records of practical issues and plausible rationales for the issues. Weekly group discussion among research team members was conducted, and the discussion records were evaluated and analyzed using a content analysis (with individual words as the unit of analysis). The codes from the analysis process were categorized into idea themes, through which the issues were extracted. The issues included those in: (a) difficulties in using multiple languages; (b) collaboration with the IT department and technical challenges (c) difficulties in recruitment; (d) difficulties in retention; (e) optimal timing; and (f) characteristics of the users. Based on the findings, we suggested researchers to plan a workable translation process, check technical needs in advance, use multiple strategies to recruit and retain research participants, plan the right time for data collection, and consider characteristics of the users in the study design

    The purpose of this paper is to identify practical issues in Internet recruitment of racial/ethnic minorities by analyzing an Internet intervention study conducted with Asian American breast cancer survivors, and to propose directions for recruitment of racial/ethnic minorities for future Internet research. Six practical issues were identified: (a) a relatively fewer number of Internet communities/groups; (b) hindrances in establishing authenticity; (c) difficulties in gaining entrée from the webmasters or website owners of Internet communities/groups; (d) the necessity of racially/ethnically matched research team members; (e) flexibility required in recruitment strategies; and (f) strategies to overcome the low response rate

    This study aimed to assess the efficacy of canal filling material removal using three different techniques after filling with a Gutta–Percha (GP) cone and calcium silicate-based sealer, by measuring the percentage of volume debris of GP and sealer remaining intracanal with micro computed tomography (micro-CT). The filling material was removed from 30 plastic teeth by a nickel–titanium (Ni–Ti) rotary retreatment system. Final irrigation was performed with 2 mL of saline and 10 specimens were randomly allocated to a conventional group. In the passive ultrasonic irrigation (PUI) group, ultrasonic irrigation was added to the conventional group (n = 10). In the Gentlefile Brush (GF Brush) group, irrigation with GF Brush was added to the conventional group (n = 10). Remaining filling material was measured using micro-CT imaging analysis. The total mean volume of residual filling material after retreatment in the conventional group, PUI group and GF Brush group were 4.84896 mm3, 0.80702 mm3, and 0.05248 mm3, respectively. The percentage of filling material remaining intracanal was 6.76% in the conventional group, 1.12% in the PUI group and 0.07% in the GF Brush group. This study shows that the cleaning effect of the GF Brush system is superior to those of Ni–Ti retreatment files and the PUI system in the apical area

    Probiotics are dietary supplements containing viable, non-pathogenic microorganisms that interact with the gastrointestinal microflora and directly with the immune system. The possible health effects of probiotics include modulating the immune system and exerting antibacterial, anticancer, and anti-mutagenic effects. The purpose of this study was to isolate, identify, and characterize novel strains of probiotics from the faeces of Korean infants. Various assays were conducted to determine the physiological features of candidate probiotic isolates, including Gram staining, 16S rRNA gene sequencing, tolerance assays to stimulated gastric juice and bile salts, adherence ability assays, antibiotic susceptibility testing, and assays of immunomodulatory effects. Based on these morphological and biochemical characteristics, five potential probiotic isolates (Enterococcus faecalis BioE EF71, Lactobacillus fermentum BioE LF11, Lactobacillus plantarum BioE LPL59, Lactobacillus paracasei BioE LP08, and Streptococcus thermophilus BioE ST107) were selected. E. faecalis BioE EF71 and L. plantarum BioE LPL59 showed high tolerance to stimulated gastric juice and bile salts, and S. thermophilus BioE ST107 as well as these two strains exhibited stronger adherence ability than reference strain Lactobacillus rhamnosus GG. All five strains inhibited secretion of lipopolysaccharide-induced pro-inflammatory cytokines IL-6 and TNF-α in RAW264.7 macrophages in vitro. L. fermentum BioE LF11, L. plantarum BioE LPL59, and S. thermophilus BioE ST107 enhanced the production of anti-inflammatory cytokine IL-10. Overall, our findings demonstrate that the five novel strains have potential as safe probiotics and encouraged varying degrees of immunomodulatory effects
