AIM: To investigate how the saturated and unsaturated fatty acid composition influences the susceptibility of developing acute pancreatitis. METHODS: Primary pancreatic acinar cells were treated with low and high concentrations of different saturated and unsaturated fatty acids, and changes in the cytosolic Ca2+ signal and the expression of protein kinase C(PKC) were measured after treatment. RESULTS: Unsaturated fatty acids at high concentrations, including oleic acid, linoleic acid, palmitoleic acid, docosahexaenoic acid, and arachidonic acid, induced a persistent rise in cytosolic Ca2+ concentrations in acinar cells. Unsaturated fatty acids at low concentrations and saturated fatty acids, including palmitic acid, stearic acid, and triglycerides, at low and high concentrations were unable to induce a rise in Ca2+ concentrations in acinar cells. Unsaturated fatty acids at high concentrations but not saturated fatty acids induced intra-acinar cell trypsin activation and cell damage and increased PKC ***: At sufficiently high concentrations, unsaturated fatty acids were able to induce acinar cells injury and promote the development of pancreatitis. Unsaturated fatty acids may play a distinctive role in the pathogenesis of pancreatitis through the activation of PKC family members.

A new finite difference lattice Boltzmann scheme is developed. Because of analyzing the influence of external body force roundly, the correct Navier-Stokes equations with the external body force are recovered, without any additional unphysical terms. And some numerical results are presented. The result which close agreement with analytical data shows the good performance of the model.

An outbreak of the sweetpotato whitefly, Bemisia tabaci （Gennadius）, biotype B occurred in the Imperial Valley, California in 1991. The insects destroyed melon crops and seriously damaged other vegetables, ornamentals and row crops. As a result of the need for sampling technology, we developed a whitefly trap （named the CC trap） that could be left in the field for extended time periods. We used the traps to monitor populations ofB. tabaci adults during year-round samplings from 1996 to 2002 to study variations in the weekly trap catches of the insect. The greatest number ofB. tabaci adults was recorded in 1996, followed by a continuing annual decrease in trap catches each year through 2002. The overall decline of B. tabaci is attributed in part to the adoption of an integrated pest management （IPM） program initiated in 1992 and reduced melon hectares from 1996 to 2002. Other factors may also have contributed to the population reductions. Seasonally, B. tabaci trap catches decreased during the late summer and fall concurrent with decreasing minimum tempera- tares that are suggested to be a significant factor affecting seasonal activity and reproduction.

We used brightfield electron microscopy （BEM）, differential interference contrast microscopy （DICM）, scanning electron microscopy （SEM）, transmission electron microscopy （TEM）, and confocal laser scanning microscopy （CLSM） to investigate the stylet pathways of Bemisia tabaci during nymphal feeding behavior in cotton leaves beginning with penetration of the abaxial leaf surface and ending with stylets in sieve tubes in phloem tissues. Most nymphal stylets within salivary sheaths penetrating leaf tissues made complex turns and developed more than one salivary sheath branch before ending in sieve tubes. The external morphology of the salivary sheaths and their routes between and through leaf cells are described during the present study. Results showed the presence of the stylet within the sieve tubes. B. tabaci nymphs may remove stylets and feed in different sieve tubes. Ten short movies showing the progression of the stylet penetrations from adaxial surface to the sieve tubes are attached to Figures 8-15. The report and movies can be viewed from the internet. Download the movies to a local drive in your computer first for fast upload. The movies are posted on the website http：//***/Services/***？docid=14629. The movies can be used as a teaching aid in biology classes.

Jingju actor and director Wu Hsing-kuo＇s （吴兴国） Lear Is Here （2001） is a 90-minute solo performance adapted from Shakespeare＇s King Lear and performed injingju style. In this performance, he alternately performs 10 male and female characters including himself injingju role types ofsheng （male）, dan （female）,jing （painted face）, mo, and chou （clown） in search 0f dual identities. This paper will investigate Wu＇s performance in Lear Is Here from three directions： First, how Wu subtly combines Shakespearean dramatic tension and psychological complex, his versatilejingju performing styles, and Brechtian alienation effect in developing his unique artistic flair？ What are at stake of such an eclectic performance？ Second, in the rooting and re-routing of both Shakespearean plays andjingju acting style where Wu Hsing-kuo meets King Lear, how Wu articulates the meticulous details of both source culture and target culture while at once extracting them out of context to interweave and re-articulate them into an eclectic intercultural theater？ Third, investigating the cultural exchange, bicroleurs, audience reception, and production mode of the work, the author will try to do away with the ＂authenticity＂ or ＂representativeness＂ of either the East or the West, but explore the possibilities of the hybrid theater in search of alternative aesthetic and emerging performance genre

With an analysis on Golden Bough Theater＇s Troy, Troy... Taiwan, this article will investigate how they de-contextualize Greek Epic Iliad with an eclectic collage of the tropes of Greek epic, the techniques of environmental theater and Taiwan Residents local opera, and the aesthetics of Taiwan Residents indigenous rituals and Pili Puppetry. It will discuss how the performers transform Greek epic into a Taiwan Residents allegory in search of Taiwan Residents cultural roots and identities. Furthermore, in the cultural encounter between the East and the West, multiple folds of significance will be explored through their hybridized performance genres and rituals as well as symbolic interaction in various performance venues with different historical and cultural legacies.

We examined the patterns of male pink bollworm （PBW）, Pectinophora gossypiella （Saunders）, moth catches in gossyplure-baited traps over a 15-year period from 1989 to 2003 in the Imperial Valley, California, USA. Monitoring was conducted during periods when different pink bollworm areawide control strategies were being used. Numbers of male pink bollworm moths caught in gossyplure-baited traps progressively decreased each year from 1990 to 1994 during short-season cotton production. High numbers of male moths caught in traps from 1995 to 1997 may have been related to moth migrations from the large cotton acreages grown in the Mexicali Valley bordering the Imperial Valley. Transgenic Bollgard （Bt） cotton was planted in 3% of the cotton area in 1996 and thereafter in 80%- 94% of the cotton area from 1997 to 2003. Pink bollworm moth trap catches were significantly lower from 1998 to 2003 than catches in 1995 to 1997, except for 1999. The trapping results suggested that Bt cotton had significant input on reduction of pink bollworm populations, confirming results of other investigators and providing additional documentation on the benefits of the Bt cotton culture.
