Abstract
PURPOSE To study the advantage of fused 3-deoxy-3-18F-fluorothymidine (FLT) positron emission tomography (PET) and computed tomography (CT) images on radiotherapy planning for esophageal carcinoma patients . METHODS Ten patients with esophageal carcinoma were referred for radiotherapy. Each patient underwent CT and FLT PET scan for simulation plan in the same treatment position. FLT PET images were coregistered with CT images. GTVCT was initially performed on CT images, GTVPET-CT were automatically segmented on FLT PET/CT images using a fixed threshold values at 1.4. Two kinds of treatment plans were designed based on GTVCT and GTVPET-CT. The radiation dose was prescribed as 60 Gy in 30 fractions. The dose-volume parameters of target volume and normal tissues, CI and HI of based on the GTVPET- CT and GTVCT were compared. RESULTS The mean GTV delineated on CT and PET- CT were 39.28 cms and 34.48 cms , respectively . The values for mean lung dose, total-lung volume receiving =5, = 10, = 20 and = 30Gy;mean heart dose, heart volume receiving =30Gy and normal tissues of plan based on the GTVPET- CT were significant lower than plan based on the GTV-CT. CONCLUSIONS In our study, FLT PET use has an impact on target delineation for radiotherapy planning. GTVPET-CT is significantly smaller than GTVCT with a mean volume reduction of 16%. CT and FLT/PET image fusion appeared to have an advantage on dose reduction of organ at risk in radiotherapy planning of esophageal carcinoma.

Abstract
Two spring wheat varieties Ningchun 4 and Chinese Spring with good and poor resistance to abiotic stress, respectively, were used to investigate proteomic changes in the developing grains under drought stress by a comparative proteomics approach. A total of 152 protein spots showed at least twofold differences in abundance on two-dimensional electrophoresis (2-DE) maps, of which 28 and 68 protein spots were identified by MALDI-TOF and MALDI-TOF/TOF mass spectrometry, respectively. Of the 96 identified protein spots, six different expression patterns were found and they were involved in stress/defense/detoxification, carbohydrate metabolism, photosynthesis, nitrogen metabolism, storage proteins and some other important functions. Comparative proteomic analysis revealed that under the drought conditions the decreased degree of ascorbate peroxidases was more significant in Chinese Spring than in Ningchun 4 during grain development whereas translationally controlled tumor protein, which was significantly upregulated at 14 DAF, was present in Ningchun 4 and absent in Chinese Spring. The Rubisco large subunit displayed an upregulated expression pattern in Ningchun 4. In addition, two drought-tolerant proteins, triosephosphate isomerase and oxygen-evolving complex showed B and F type expression patterns in Chinese Spring, but D and B types in Ningchun 4, respectively. These differentially expressed proteins might be responsible for the stronger drought resistance of Ningchun 4 compared to Chinese Spring.

Abstract
This paper studies the cumulative effect of various parameters, namely anionic polyacrylamide (APAM) concentration, oil concentration, pH, trans-membrane pressure (TMP), and total dissolved solid (TDS), and obtains optimal parameters for the minimum relative flux (J/J(0)) declining in aqueous solutions with response surface methodology (RSM). In order to analyze the mutual interaction and optimal values of parameters affecting ultrafiltration, a central composite rotatable design (CCRD), one method of RSM, was employed. The analysis of variance (ANOVA) of the cubic polynomial model demonstrated that this model was highly significant and reliable. The results show that the effect of APAM and oil on J/J(0) has an inverse trend with pH value increasing. Moreover, the mutual interaction of initial APAM (oil) concentration (C(APAM(oil))) and pH (TMP) were negligible, while the mutual interaction of C(APAM) and C(oil) has an obvious effect, i.e. the effect of initial feed C(APAM) became more important at higher values of initial feed C(oil), and the J/J(0) was only about 4%. The favorable operate conditions in this ultrafiltration process were at low C(APAM), C(oil), pH, and TMP, which agreed with the conclusions of many authors, while considering water production, C(APAM) and C(oil) < 50 mg/L, pH < 4, and TMP < 0.075 MPa could be accepted.

Abstract
Native cowhage spicules, and heat-inactivated spicules containing histamine or capsaicin, evoke similar sensations of itch and nociceptive sensations in humans. In ongoing studies of the peripheral neural mechanisms of chemical itch and pain in the mouse, extracellular electrophysiological recordings were obtained, in vivo, from the cell bodies of mechanosensitive nociceptive neurons in response to spicule stimuli delivered to their cutaneous receptive fields (RFs) on the distal hindlimb. A total of 43 mechanosensitive, cutaneous, nociceptive neurons with axonal conduction velocities in the C-fiber range (C-nociceptors) were classified as CM if responsive to noxious mechanical stimuli, such as pinch, or CMH if responsive to noxious mechanical and heat stimuli (51°C, 5 s). The tips of native cowhage spicules, or heat-inactivated spicules containing histamine or capsaicin, were applied to the RF. Heat-inactivated spicules containing no chemical produced only a transient response occurring during insertion. Of the 43 mechanosensitive nociceptors recorded, 20 of the 25 CMHs responded to capsaicin, and of these, 13 also responded to cowhage and/or histamine. In contrast, none of the 18 CMs responded to any of the chemical stimuli. The time course of the mean discharge rate of CMHs was similar in response to each type of spicule and generally similar, although reaching a peak earlier, to the temporal profiles of itch and nociceptive sensations evoked by the same stimuli in humans. These findings are consistent with the hypothesis that the itch and nociceptive sensations evoked by these punctuate chemical stimuli are mediated at least in part by the activity of mechanoheat-sensitive C-nociceptors. In contrast, activity in mechanosensitive C-nociceptors that do not respond to heat or to pruritic chemicals is hypothesized as contributing to pain but not to itch.

Abstract
The pathogenesis of cancer is remained to be further understood. This study aims to investigate the role of tumour-derived Foxhead box P3 (Foxp3)(+) interleukin (IL)-17(+) T cells on suppressing tumour-specific CD8(+) T cells. Colorectal cancer (CRC) tissue was collected from surgically removed cancer tissue of 22 patients with CRC. Foxp3(+) IL-17(+) T cells in cancer tissue were examined by flow cytometry. A set of cell markers and cytokines expressed by Foxp3(+) IL-17(+) T cells were determined by immune staining. By coculture with isolated peripheral CD8(+) T cells, the immune regulatory capacity of Foxp3(+) IL-17(+) T cells was examined. The results showed that a number of Foxp3(+) IL-17(+) T cells were found in CRC tissue (22.8 ± 2.6 cells/mm(2) tissue) that was significantly more than in non-cancer colonic mucosa (5.6 ± 1.04 cells/mm(2) tissue). The Foxp3(+) IL-17(+) cells also CD4(+), CCR6(+), transforming growth factor (TGF)-beta(+) and IL-6(+) . The CD8(+) T cells proliferated markedly after exposure to tumour protein in culture that was suppressed in the presence of CRC-derived Foxp3(+) IL-17(+) T cells; the suppression was attenuated by pretreatment with anti-IL-17 antibody. We conclude that CRC-derived Foxp3(+) IL-17(+) T cells have the ability to suppress tumour-specific CD8(+) T cells. This subset of T cells may be a novel therapeutic target in the treatment of CRC.

Abstract
Maize cDNA expression library was screened using the antibodies against ABA-binding proteins (ABBP). From 200 000 separated phage plaques, only one cDNA clone coding for a polypeptide was obtained. It shows 60%-65% homology to the genes of nucleic acid-binding proteins in mammalia. However, about 120 cDNA clones coding maize 17s rRNA were unexpectedly obtained. In view of this, the ABBP purified by ABA affinity chromatography and the antibodies derived from the purified ABBP were examined. It is found that rRNA is indeed present in the ABBP. In addition, the obtained antibodies could recognize RNA as well as ABBP. It is suggested that the ABBP have nucleic acid-binding property and can form a complex with rRNA.
