During the encapsulation Z-IETD-FMK process, polyethyleneglycol was used as an additive to improve the immobilization efficiency. After encapsulation, the pore size, morphology and other features were characterized by various methods, including scanning electron microscopy, nitrogen adsorption-desorption analysis, transmission electron microscopy, fourier transform infrared spectroscopy, and elemental analysis. Furthermore, the capacity of ethanol production by immobilized Zymomonas mobilis and free Zymomonas mobilis was compared. Conclusions/Significance: In this study, Zymomonas mobilis cells were successfully encapsulated in mesoporous silica-based materials under mild conditions
by the “fish-in-net” approach. Encapsulated cells could perform normal metabolism and exhibited excellent
reusability. The results presented here illustrate the enormous potential of the “fish-in-net” approach for immobilization of living cells.”
“Background/Aims: At least 6-10 min of withdrawal time is currently recommended to optimize polyp yield in screening colonoscopies in individual with intact colon. We aimed to assess whether formal documentation of withdrawal time could improve the quality of colonoscopy observation.\n\nMethodology: During December 2006, we implemented withdrawal time as a mandatory field for formal colonoscopy report. Colonoscopy withdrawal time and adenoma detection rate was compared between periods before (Nov 2006) and after (Jan 2007) formal documentation. A total of 709 colonoscopic procedures, beta-catenin cancer Cl-amidine price which were performed by 9 colonoscopists in training (fellows) were analyzed.\n\nResults: The median withdrawal time of ‘negative colonoscopy’ increased from 6m06s to 6m36s (p=0.045). The number of adenoma detected in each colonoscopy between the two periods was 0.66 and 0.81 (p=0.813). Two out of 9 colonoscopists increased withdrawal time significantly (6m11s to 7m52s, p=0.001) after formal documentation of withdrawal time and demonstrated higher detection rate for adenoma smaller
than 10mm (0.34 per colonoscopy vs. 0.83 per colonoscopy; p=0.012).\n\nConclusions: Formal documentation of withdrawal time forced colonoscopists to lengthen actual withdrawal time. Routinization of formal documentation of withdrawal time might be helpful in improving quality of colonoscopy.”
“Focus groups (n = 65) were conducted with Hmong adults in St. Paul/Minneapolis, MN to determine how environmental factors, acculturation, and food insecurity influence dietary behavior, body mass index (BMI), and health. Acculturation was assessed by examining linguistic, social, and eating behavior, length of time in the US, and BMI for B-TL(1) (born in Thailand/Laos and in US <= 5 years), B-TL(2) (in Thailand/Laos through adolescence, had food memories, and in US > 5 years), and B-US (born in US or in Thailand/Laos less than 8 years and no food memories from there).
