Magnetic resonance imaging(MRI)techniques for assessment of morphology and function of the pancreas have been improved dramatically the recent years and MRI is very often used in diagnosing and follow-up of chronic pancreatitis(CP)*** MRI including fat-suppressed T1-weighted and T2-weighted imaging techniques reveal decreased signal and glandular atrophy of the pancreas in *** contrast-enhanced MRI of the pancreas in CP the pancreatic signal is usually reduced and delayed due to decreased perfusion as a result of chronic inflammation and ***,morphological changes of the ductal system can be assessed by magnetic resonance cholangiopancreatography(MRCP).Furthermore,secretin-stimulated MRCP is a valuable technique to evaluate side branch pathology and the exocrine function of the pancreas and diffusion weighted imaging can be used to quantify both parenchymal fibrotic changes and the exocrine function of the *** standard and advanced MRI techniques are supplementary techniques to reveal morphological and functional changes of the pancreas in ***,spectroscopy has been used for assessment of metabolite concentrations in-vivo in different tissues and may have the potential to offer better tissue characterization of the ***,the purpose of the present review is to provide an update on standard and advanced MRI techniques of the pancreas in CP.

Drosophila melanogaster is often used as a model organism in evolution- ary biology and ecophysiology to study evolutionary processes and their physiological mechanisms. Diets used to feed Drosophila cultures differ between laboratories and are often nutritious and distinct from food sources in the natural habitat, Here we rear D. melanogaster on a standard diet used in our laboratory and a field diet composed of decomposing apples collected in the field. Flies developed on these two diet compositions are tested for heat, cold, desiccation, and starvation resistance as well as developmental time, dry body mass and fat percentage. The nutritional compositions of the standard and field diets were analyzed, and discussed in relation to the phenotypic observations. Results showed marked differences in phenotype of flies from the two types of diets. Flies reared on the field diet are more starvation resistant and they are smaller, leaner, and have lower heat resistance compared to flies reared on the standard diet. Sex specific effects of diet type are observed for several of the investigated traits and the strong sexual dimorphism usually observed in desiccation resistance in D. melanogaster disappeared when rearing the flies on the field diet. Based on our results we conclude that care should be taken in extrapolating results from one type of diet to another and especially from laboratory to field diets.

Sociology Study 2011年第7期1卷 484-490页

There is a need for cost-efficient methods in consumer research. Existing qualitative methods are expensive to conduct. This paper aims to improve the focus group method. The objective was to improve focus groups with different aims： shorter time conducting interviews, interview greater number of respondents, deliver results faster than traditionally analysis of data, and lower total cost. CurroCus groups of 15-45 minutes duration were tested in five different experiments, including 70 to 160 respondents in groups of 7-11 respondents. The name of the new method is formed from the word ＂Curro＂ in Latin that means speed in English, and ＂Cus＂ that is the last syllable of the word ＂focus＂, thereby forming a new word： CurroCus~ on the method. The results from testing of the CurroCus~ group method at different cases showed that trained moderators and observers could collect relevant responses in a given time for each group. It was possible to process a number of 6 to 10 respondents for each group. By conducting several successive groups, saturation of information was reached after an adequate number of CurroCus~ groups. Therefore, the total number of respondents can be optimized and results can be more precise, with reduced risk of inaccuracy. At the same time, the cost for each case can be lowered substantially, in our cases to approximately 1/10 of a traditional focus group cost. The role （skills） of the moderator is important. A disadvantage is the risk that some of the respondents are not able to express their thoughts in due time when time is limited. There is a need for more research on all parts of the CurroCus group process.
