Chronic inflammation is thought to be the leading cause of colorectal cancer, and interleukin-10 (IL10) has been identified as a potent immunomodulatory cytokine that regulates inflammatory responses in the gastrointestinal tract. Although several single nucleotide polymorphisms (SNPs) in IL10 have been associated with the risk of colorectal cancer, their prognostic significance has not been determined. Two hundred and eightytwo colorectal cancer patients were genotyped for two candidate cancer-associated SNPs in IL10. The associations of these SNPs with distant metastasis-free survival and overall survival were evaluated by Kaplan-Meier analysis and Cox regression model. The minor homozygote GG genotype of IL10 rs3021094 was significantly associated with a 3.30-fold higher risk of death compared with the TT+TG genotypes (P = 0.011). The patients with IL10rs3021094 GG genotype also had a poorer overall survival in Kaplan-Meier analysis (log-rank P = 0.007) and in multivariate Cox regression model (P = 0.044) adjusting for age, gender,carcinoembryonic antigen levels, tumor differentiation, stage, lymphovascular invasion,and perineural invasion. In conclusion, our results suggest that IL10 rs3021094 might be a valuable prognostic biomarker for colorectal cancer patients.
EMBRYOS OF EARLY CRETACEOUS CHORISTODERA (REPTILIA) FROM THE JEHOL BIOTA IN WESTERN LIAONING, CHINA

Choristodera는 잘 알려지지 않은 그룹이지만 매우 독특한 해양 파충류로 후기 트라이아스기에서부터 후기 올리고세까지 아시아, 북미, 유럽에 걸쳐 산출된다. 비록 수천 개의 choristodera 표본이 중국 전기 백악기 Jehol biota에서 수집되었지만 바다거북처럼 난태생이였는지 Pachypleurosauria (해양파충류) Keichousaurus hui처럼 태생이었는지 아직 확실하게 밝혀지지 않았다. 우리는 이 논문에서 중국 서부 요녕성의 Jiufotang층에서 산출된 가죽질의 알껍데기가 함께 잘 보존된 Hyphalosaurus baitaigouensis (파충류, Choristodera)를 보고한다. 이것은 Hyphalosaurus baitai-gouensis 같은 choristoderian 파충류가 남중국 Guizhou에서 산출된 후기 트라이아스기 Keichousaurus hui처럼 태생이었을 것임을 지시하는 직접적인 첫 번째 증거다. The Choristodera is a poorly known clade, but very a distinctive group of aquatic reptiles, which has been found from the Late Triassic to the Late Oligocene in Asia, North America and Europe. Although thousands of choristoderian specimens have been collected from the Early Cretaceous non-marine beds in Liaoning, China, no direct evidences have been found to determine whether they were oviparous like sea turtles or viviparous like Keichousaurus hui of Pacbypleurosauria (marine reptiles). Here we report a well-preserved specimen of Hyphalosaurus baitaigouensis with leathery embryonic eggs from the Jiufotang Formation in western Liaoning, China. It provides the first direct evidence to indicate that choristoderian reptiles are most likely viviparous like Late Triassic Keichousaurus hui from Guizhou, Southern China.
Microwave-assisted Approach for the Rapid Enzymatic Digestion of Rapeseed Meal
Ju-Fang Li,Fang Wei,Lu-Lu Guo,Gang-You Yuan,Feng-Hong Huang,Mu-Lan Jiang,Yuan-Di Zhao,Xu-Yan Dong,Guang-Ming Li,Hong Chen 한국식품과학회 2010 Food Science and Biotechnology Vol.19 No.2
This study demonstrates the use of a new microwave-assisted approach for accelerating the enzymatic digestion of rapeseed meal. The effects of different microwave parameters, such as the time, temperature, and power level, on the degree of hydrolysis (DH) were investigated by using response surface methodology (RSM). The maximum predicted DH value (10.2%) was in good agreement with the value obtained experimentally using an alkaline protease, which was 12.57% under optimal conditions. In only 7 min, the microwave-assisted method achieved a DH value similar to that obtained by the conventional enzymatic digestion method (4 hr). Therefore,this new technique for rapid enzymatic digestion will improve the application of rapeseed meal in the preparation of protein hydrolysates for use in food and feed.

The pigment gland is an important character of the Gossypium plant. With the aim of identifying genes involved in pigment gland morphogenesis in cotton, gene expression during pigment gland morphogenesis in Chuan 2802, which is glanded both in seed and plant, and a glandless line N5 was profiled using Affymetrix Cotton microarray. The results showed that there were 564 differentially expressed genes greater than twofold during gland morphogenesis. About 60.2% of these genes shares similarity with known genes on GenBank and about 39.8% with no functional description in the database. These described genes may play roles in defense response, response to oxidative stress, peroxidase activity, and the other metabolic pathways. The KEGG Orthology-Based Annotation System indicated that these above twofold expressed genes involved seven biochemical pathways on KEGG. These findings suggest that a complicated regulation is associated with pigment gland morphogenesis and the associated defense response including gossypol biosynthesis in cotton.

A cDNA encoding a novel cysteine proteinase inhibitor (CPI) was isolated from a gland mutant Xiangmian-18 of upland cotton during the pigments gland forming stage. The cDNA comprises 378 bp and encodes 125 amino acid residues with molecular mass of 13.8 kDa. It contains the conserved motif of cysteine protease inhibitors and belongs to the cystatin superfamily (Gln- Val-Val-Ala-Gly). The deduced amino acid sequences of the domains are highly similar to the normal upland cotton (96.8%). SDS-PAGE and western hybridization analysis showed that the expressed recombinant protein was recombinant CPI. The inhibitory activity of recombinant CPI was 46 u/μg which was measured by inhibiting the protease activity of papain. RT-PCR results indicated that the expression level of developing gland stage was higher than that of undeveloped gland stage.
