“This study investigates the varietal effects on volatile components and fatty acids composition (analysed by GC-MS and GC, respectively) as well as the antibacterial propriety (using microdilution test) from four Tunisian pomegranate flower cultivars (Tounsi, see more Nabli, Gabsi and Chelfi). The Chelfi flowers seemed

to be the richest in terpenoids (28.39%), aldehydes (13.24%) and alcohols (22.30%). Those volatiles seemed to be the most important groups with apparent difference between varieties. Fatty acid profiles varied significantly among cultivars. The most abundant saturated fatty acid was palmitic acid where Nabli cultivar exhibited the highest amount (435.80 mu g/g). However, Gabsi cultivar had the highest content of unsaturated fatty acids where the linolenic acid and linoleic acid were the most frequent polyunsaturated fatty acids with 254.42 and 707.73 mu g/g, respectively. Results presented here may suggest that the volatiles fraction of Compound C cell line the studied cultivars possess antimicrobial activities. This work gives further knowledge for extensive development of this medicinal plant. (C) 2013 Elsevier B.V. All rights reserved.”
“Background: Defining what constitutes a resident care unit in nursing home research is both a conceptual and

practical challenge. The aim of this paper is to provide evidence in support of a definition of care unit in nursing homes by demonstrating: (1) its feasibility for use in data collection, (2) the acceptability of aggregating individual responses to the unit level, and (3) the benefit of including unit level data in explanatory models.

Methods: An observational study design was used. Research (project) managers, healthcare aides, care managers, nursing home administrators and directors of care from thirty-six

nursing homes in the Canadian prairie provinces of Alberta, Ricolinostat in vivo Saskatchewan and Manitoba provided data for the study. A definition of care unit was developed and applied in data collection and analyses. A debriefing session was held with research managers to investigate their experiences with using the care unit definition. In addition, survey responses from 1258 healthcare aides in 25 of the 36 nursing homes in the study, that had more than one care unit, were analyzed using a multi-level modeling approach. Trained field workers administered the Alberta Context Tool (ACT), a 58-item self-report survey reflecting 10 organizational context concepts, to healthcare aides using computer assisted personal interviews. To assess the appropriateness of obtaining unit level scores, we assessed aggregation statistics (ICC(1), ICC(2), eta(2), and omega(2)), and to assess the value of using the definition of unit in explanatory models, we performed multi-level modeling.
