The optical properties of graphene coated D-shaped single mode fiber and photonic crystal fiber are numerically analyzed. Enhancement of the graphene-light interaction is found in graphene coated D-shaped photonic crystal fiber,which introduces a tunable polarization of the D-shaped fiber by changing the chemical potential of the coated *** optimal polarizer model is demonstrated with the extinction ratio of 66.26 dB/mm and the insertion loss of 9.4 dB/*** modulator extinction ratios of the TE mode and TM mode are 11.5 dB and 5 dB, respectively, with a device length of100 μm. This paper provides a theoretical reference for the optical property research of the graphene fiber.

AIM:To explore the effectiveness of acupuncture transcutaneous electrical nerve stimulation(Acu-TENS), a non-invasive modality in reduction of rectal discomfort during barostat-induced rectal distension. METHODS:Forty healthy subjects were randomized to receive 45 min of either Acu-TENS or placebo-TENS(no electrical output)over acupuncture points Hegu(largeintestine 4),Neiguan(pericardium 6)and Zusanli(stomach 36).A balloon catheter attached to a dual-drive barostat machine was then inserted into the subjects'rectum.A step-wise(4 mmHg)increase in balloon pressure was induced until maximal tolerable or 48 *** analogue scale and a 5-point subjective discomfort scale(no perception,first per-ception of distension,urge to defecate,discomfort/ pain and extreme pain)were used to assess rectal discomfort at each distension *** beta-endorphin levels were measured before,immediately after intervention,at 24 mmHg and at maximal toler- able distension pressure. RESULTS:There was no difference in the demographic data and baseline plasma beta-endorphin levels between the two *** threshold levels were higher in the Acu-TENS group when compared to the placebo group,but the difference reached statistical significance only at the sensations"urge to defecate"and"pain".The distension pressures recorded at the"urge to defecate"sensation for the Acu-TENS and placebo-TENS groups were 28.0±4.5 mmHg and 24.6±5.7 mmHg,respectively(P=0.043);and the pressures recorded for the"pain"sensation for these two groups were 36.0±4.2 mmHg and 30.5± 4.3 mmHg respectively(P=0.002).Compared to the placebo group,a higher number of participants in the Acu-TENS group tolerated higher distension pressures (>40 mmHg)(65%in Acu-TENS vs 25%in placebo, P=0.02).The plasma beta-endorphin levels of the Acu-TENS group were significantly higher than that of the placebo group at barostat inflation pressure of 24 mmHg(1.31±0.40 ng/mL vs 1.04±0.43 ng/mL,P= 0.044)and at maximal inflation p

Establishment of a Tumor-bearing Mouse Model Stably Expressing EgFP Labeled Human MUC1 VNTRs

引用

Chemical Research in Chinese Universities 2008年第4期24卷 505-510页

作者： ZHANg Shu-zi ZHANg Hai-hong ZHANg wa SHI He-liang YU Xiang-hui KONg Wei LI Wei Vaccine Research Center College of Life Science Jilin University Changchun 130012 P R. China

Two eukaryotic vectors expressing 9 tandem repeats of human MUCI（VNTR）, VR1012-VNTR, and pEgFP-VNTR, were constructed by cloning VNTR gene into VR1012 and pEgFP, respectively. VNTR stably expressing murine Lewis lung carcinoma（LLC） cell line（VNTR^＋ LLC） was established by Lipofectamine-mediated transfection of pEgFP-VNTR into LLC cells. The EgFP expression was observed under a fluorescent microscope and VNTR expression in VNTR^＋ LLC cells was confirmed by means of Western blotting. A syngenic graft tumor model was generated by subcutaneous injection of VNTR^＋ LLC cells into C57/BL6 mice and tumor size increased rapidly with time and in a cell qumber dependent manner. VNTR mRNA expression in the tumor formed was confirmed by RT-PCR. After the third immunization mice were challenged subcutaneously with 5×10^5 VNTR^＋ LLC cells, a significant reduction of subcutaneous tumor growth was observed in the groups immunized with VNTR plasmid DNA compared with that in the groups immunized with the vector DNA alone. Thus, the suppression of subcutaneous tumor was antigen-specific. This model is useful for the development of tumor vaccines targeting MUCI VNTRs.

Acta Oceanologica Sinica 2008年第z1期27卷 46-59页

作者： PHILIP D Osborne Pacific International Engineering PLLC

A local-scale phase-resolving wave transformation model with CgwaVE is established in connection with a regional-scale coupled STwaVE-ADCIRC wave-current model for its application in the Half Moon Bay, grays *** transformation from offshore to the harbor entrance is simulated by the STwaVE model which includes wave-current *** STwaVE results provide incident wave conditions for the local-scale CgwaVE model at its outer boundary. A simple method is developed to take into account the lateral variation of wave height in constructing the model’s wave boundary *** model was validated for three wave condition cases which yielded good agreement with field *** validated model was applied to predicting nearshore waves in the Half Moon Bay and longshore transport parameters along the wave breaking line for the existing condition and three engineering alternatives. A comparative analysis indicated that storm waves that have a combination of long period and large height are the most destructive to the crenulate shoreline in the Half Moon Bay; both 152 m jetty extension (Alt. 2) and diffraction mound enlargement (Alt. 3) would significantly reduce breaking wave height and longshore transport potential in the southwest corner of Half Moon Bay.
