The carboxymethyl cellulose sodium aqueous solution, in which α-tocopherol droplets containing the powdery artificial diet were dispersed, was dropped or sprayed into the chitosan aqueous solution. Microcapsules were prepared by forming polyionic complex shell made from chitosan and carboxymethyl cellulose sodium. In the experiment, the concentration of carboxymethyl cellulose sodium (CMCNa) was mainly changed to investigate the effect on the diameters of microcapsules, the content and the microencapsulation efficiency. The microcapsules couldn’t be prepared with the concentration of carboxymethyl cellulose sodium less than 3.0 wt%. The microcapsules were the core-shell type. The diameters of microcapsules were increased with the concentration of CMCNa and the microencapsulation efficiency of ca. 100% could be obtained by the preparation method presented in this study. The microcapsules were found to be eaten well by tropical fishes and to prevent water environmental pollution.展开更多

METHODS: Twenty nephrotic syndrome (NS) Wistar rats administrated adriamycin (ADR) with a single intravenous dose of 5 mg/kg body weight, were divided into the standard and high-lipid chow groups. Another 20 weight-matched non-NS rats that received a vehicle alone were grouped as control. Urinary protein excretion and serum cholesterol were assayed; image analysis and techniques of pathology, immunohistochemistry, and molecular biology were used to determine morphological changes in glomeruli and the production of glomerular mesangial matrices in different groups. RESULTS: The serum total cholesterol level was significantly higher in rats with high-lipid chow in both non-NS [(2.2 +/- 0.3) g/L vs. (0.9 +/- 0.1) g/L, P展开更多

However, little is known regarding which devices are most effective for changing these behaviors, and whether or not these devices or accompanying applications (apps) are feasible or desired vehicles for behavior change. Four focus groups were conducted with students from a Western university who were given iPads to download diet-related apps. Participants were asked questions about preferences regarding iPad functionality, app functionality, and the likelihood of using apps and iPads for facilitating diet-related behavior change in the future. Two key themes emerged from focus group discussions on diet-related apps for iPads and their usefulness to facilitate behavior change. The first theme, lack of iPad practicality, contained three subthemes: inconvenient mid-way technology, internet access barriers, and smart-phone preference. The second theme that emerged was attitudes towards apps in general. Three subthemes were identified under the second theme: too intensive;positive functions not specific to iPads;and lack of reliable/trustworthy information. This paper is the first, to this author’s knowledge, to report the use of qualitative methods to study the practicality of using apps and iPads in changing dietrelated behaviors. Early generations of iPads may not be effective devices for facilitating behavior change among college students;and diet-related apps seem to have poor functionality that lead to cessation of use.展开更多
