3Characterization of six tumorsuppressor genes and microsatellite instability in hepatocellular carcinomain southern African blacks显示文摘AIM To analyse cumulative loss of heterozygosity (LOH) of chromosomal regions and tumor suppressor genes in hepatocellular carcinomas (HCCs) from 20 southern African blacks. METHODS p53, RB1, BRCA1, BRCA2, WT1 and E cadherin genes were analysed for LOH, and p53 gene was also analysed for the codon 249 mutation, in tumor and adjacent non tumorous liver tissues using molecular techniques and 10 polymorphic microsatellite markers. RESULTS p53 codon 249 mutation was found in 25% of the subjects, as was expected, because many patients were from Mozambique, a country with high aflatoxin B 1 exposure. LOH was found at the RB1, BRCA2 and WT1 loci in 20%(4/*!20) of the HCCs, supporting a possible role of these genes in HCC. No LOH was evident in any of the remaining genes. Reports of mutations of p53 and RB1 genes in combination, described in other populations, were not confirmed in this study. Change in microsatellite repeat number was noted at 9/*!10 microsatellite loci in different HCCs, and changes at two or more loci were detected in 15%(3/*!20) of subjects. CONCLUSION We propose that microsatellite/genomic instability may play a role in the pathogenesis of a subset of HCCs in black Africans.Martins C Kedda MA Kew MC 1999World Journal of Gastroenterology1999,5,6:21
4miR-182参与调节胶质母细胞瘤的凋亡、生长和分化(英文)显示文摘Glioblastoma multiforme(GBM)is a lethal,therapy-resistant brain cancer consisting of numerous tumor cell subpopulations,including stem-like glioma-initiating cells(GICs),which contribute to tumor recurrence following initial response to therapy.Here,we identified miR-182 as a regulator of apoptosis,growth,and differentiation programs whose expression level is correlated with GBM patient survival.Repression of Bcl2-like12(Bcl2L12),c-Met,and hypoxia-inducible factor 2α(HIF2A)is of central importance to miR-182 anti-tumor activity,as it results in enhanced therapy susceptibility,decreased GIC sphere size,expansion,and stemness in vitro.To evaluate the tumor-suppressive function of miR-182 in vivo,we synthesized miR-182-based spherical nucleic acids(182-SNAs);i.e.,gold nanoparticles covalently functionalized with mature miR-182 duplexes.Intravenously administered 182-SNAs penetrated the bloodbrain/blood-tumor barriers(BBB/BTB)in orthotopic GBM xenografts and selectively disseminated throughout extravascular glioma parenchyma,causing reduced tumor burden and increased animal survival.Our results indicate that harnessing the anti-tumor activities of miR-182 via safe and robust delivery of 182-SNAs represents a novel strategy for therapeutic intervention in GBM.Kouri FM Hurley LA Daniel WL Day ES Hua Y Hao L Peng CY Merkel TJ Queisser MA Ritner C Zhang H James CD Sznajder JI Chin L Giljohann DA Kessler JA Peter ME Mirkin CA Stegh AH 2015中华神经外科疾病研究杂志2015,14,2:14
5Clostridium difficile infections in China显示文摘Clostridium difficile (C. difficile) infection has become one of the major hospital-associated infections in West-ern countries in the last two decades. However, there is limited information on the status of C. difficile infection inChinese healthcare settings. Given the large and increasing elderly population and the well-recognized problem ofover-prescribing of broad spectrum antibiotics in China, it is critical to understand the epidemiology and potentialrisk factors that may contribute to C. difficile infection in China. A literature review of available published studies,including those in Chinese language-based journals, was conducted. A review of the currently available literaturesuggested the presence of C. difficile infections in China, but also suggested that these infections were not particu-larly endemic. This finding should lead to better designed and greatly expanded studies to provide a more reliableepidemiologically-based conclusion on the actual status of C. difficile infection in China, including the identifica-tion of any associated risk factors. Such information is ultimately valuable to develop appropriate strategies to pre-vent C. difficile infection and the vast negative impact of such infections in China and other developing countries.Ke Jin a,b,c,Shixia Wang c,d,Zuhu Huang a,b,c,Shan Lu b,c,daDepartment of Infectious Diseases,bJiangsu Province Key Laboratory in Infectious Diseases,cChina-US Vaccine ResearchCenter,the First Affiliated Hospital of Nanjing Medical University,Nanjing,Jiangsu 210029,China d Department of Medicine,University of Massachusetts Medical School,Worcester,MA 01655,USA. 2010The Journal of Biomedical Research2010,24,6:14
6Overexpression of an ABA biosynthesis gene using a stress-inducible promoter enhances drought resistance in petunia显示文摘The response of plants to drought stress includes reduced transpiration as stomates close in response to increased abscisic acid(ABA)concentrations.Constitutive overexpression of 9-cis-epoxycarotenoid dioxygenase(NCED),a key enzyme in ABA biosynthesis,increases drought resistance,but causes negative pleiotropic effects on plant growth and development.We overexpressed the tomato NCED(LeNCED1)in petunia plants under the control of a stress-inducible promoter,rd29A.Under water stress,the transgenic plants had increased transcripts of NCED mRNA,elevated leaf ABA concentrations,increased concentrations of proline,and a significant increase in drought resistance.The transgenic plants also displayed the expected decreases in stomatal conductance,transpiration,and photosynthesis.After 14 days without water,the control plants were dead,but the transgenic plants,though wilted,recovered fully when re-watered.Well-watered transgenic plants grew like non-transformed control plants and there was no effect of the transgene on seed dormancy.Alejandro C Estrada-Melo Chao Ma Michael S Reid Cai-Zhong Jiang 2015Horticulture Research2015,2,1:12

14Sol-gel derived HA/TiO_2 double coatings on Ti scaffolds for orthopaedic applications显示文摘Hydroxyapatite/titania (HA/TiO2) double layers were coated onto Ti scaffolds throughout for orthopaedic applications by sol-gel method. Differential scanning calorimetry (DSC), thermogravimetric analysis (TG) and X-ray diffractometry (XRD) were used for the characterisation of the phase transformations of the dried gels and coated surface structures. Scanning electron microscope (SEM) equipped with energy dispersive spectrometry (EDS) was used for the observation and evaluation of the morphology and phases of the surface layers and for the assessment of the in vitro tests. The in vitro assessments were performed by soaking the HA/TiO2 double coated samples into the simulated body fluid (SBF) for various periods. The TiO2 dipping-coating method at a speed of 12 cm/min, followed by a heat treatment at 600 ℃ for 20 min. The HA la lyaeyre wr wasa ssu cbosaetqeude bnytl ya dipping-coated on the outer surface at the same speed and then heat-treated at difference temperatures. The results indicat that the HA phase begins to crystallize after a heat treatment at 560 ℃. The crystallinity increases obviously at 760 ℃. SEM observations find no delamination or crack at the interfaces of HA/TiO2 and TiO2/Ti. The HA/TiO2 coated Ti scaffolds displays excellent bone-like apatite forming ability when it is soaked into SBF. Ti scaffolds after HA/TiO2 double coatings can be anticipated as promising implant materials for orthopaedicXU W HU W Y LI M H MA Q Q P. D. HODGSON WEN C E 2006中国有色金属学会会刊:英文版2006,16,B01:5

16^137Cs tracing dynamics of soil erosion,organic carbon,and total nitrogen in terraced fields and forestland in the Middle Mountains of Nepal显示文摘The Middle Mountains is one of the regions of Nepal most vulnerable to water erosion, where fragile geology, steep topography, anomalous climatic conditions, and intensive human activity have resulted in serious soil erosion and enhanced land degradation. Based on the 137 Cs tracing method, spatial variations in soil erosion, organic carbon, and total nitrogen(TN) in terraced fields lacking field banks and forestland were determined. Soil samples were collected at approximately 5 m and 20 m intervals along terraced field series and forestland transects respectively. Mean 137 Cs inventories of the four soil cores from the reference site was estimated at 574.33 ± 126.22 Bq m-2(1 Bq(i.e., one Becquerel) is equal to 1 disintegration per second(1 dps)). For each terrace, the 137 Cs inventory generally increased fromupper to lower slope positions, accompanied by a decrease in the soil erosion rate. Along the entire terraced toposequence, 137 Cs data showed that abrupt changes in soil erosion rates could occur between the lower part of the upper terrace and the upper part of the immediate terrace within a small distance. This result indicated that tillage erosion is also a dominant erosion type in the sloping farmland of this area. At the same time, we observed a fluctuant decrease in soil erosion rates for the whole terraced toposequence as well as a net deposition at the toe terrace. Although steep terraces(lacking banks and hedgerows) to some extent could act to limit soil sediment accumulation in catchments, soil erosion in the terraced field was determined to be serious. For forestland, with the exception of serious soil erosion that had taken place at the top of slopes due to concentrated flows from a country road situated above the forestland site, spatialvariation in soil erosion was similar to the 'standard' water erosion model. Soil organic carbon(SOC) and TN inventories showed similar spatial patterns to the 137 Cs inventory for both toposequences investigated. However, due to the different dominant erosion processes between the two, we found similar patterns between the <0.002 mm soil particle size fraction(clay sized) and 137 Cs inventories in terraced fields, while different patterns could be found between 137 Cs inventories and the <0.002 mm soil particle size fraction in the forestland site. Such results confirm that 137 Cs can successfully trace soil erosion, SOC and soil nitrogen dynamics in steep terraced fields and forestland in the Middle Mountains of Nepal.SU Zheng-an XIONG Dong-hong DENG Wei DONG Yi-fan MA Jing PADMA C Poudel GURUNG B Sher 2016Journal of Mountain Science2016,13,10:4

18Variations in Wool Growth with Nutrient Supply in Northern China显示文摘Field studies on essessment of nutritional status of the grazing sheep were carried out in each of the three major grassland regions, the eastern Inner Mongolia and beyond grassland, the Inner Mongolia - Ningxia - Gansu grassland and the Xinjiang grassland, in northern China. The results obtained showed that the wool production of fine wool sheep in these regions varied between regions and seasons, with similar seasonal patterns in all regions and that reducing the seasonal variations in nutrient supply would enhance wool production substantially. Nutritional limitations to wool growth of the grazing sheep in these regions were suggested, those were: the shortage of protein supply in winter and early spring; the poor quality of much of the pasture and the hay used as supplements, the low energy intake during winter which probably necessitated the use of body stores to maintain body temperature.D X Lu,Iner(Mongolia Academy of Animal Sciences.Hohhot City.Inner Mongolia Autgolia Autonmous Region.PRC)Z C Feng,(Mongolia Academy of Animal Sciences.Hohhot City.Inner Mongolia Autgolia Autonmous Region.PRC)H R Wang,(Mongolia Academy of Animal Sciences.Hohhot City.Inner Mongolia Autgolia Autonmous Region.PRC)R Z Yang,(Xinjiang Institute of Animal Science.Xinjiang Academy of Animal Science.Yiu Hou Road.Urumqi.Xinjiang Uygur Autonomous Region PRC)C T Ma,(Chinese Academy of Agricultural Sciences.Lanzhou.Gansu.PRC)D B Purser,(CSIRO Division of Animal Production.Laboratory for Rural Research.Private Bag.P.O.Wembley.Western Australia 6014)J R Lindsay(CSIRO Division of Animal Production.Laboratory for Rural Research.Private Bag.P.O.Wembley.Western Australia 6014)D W Peter(CSIRO Division of Animal Production.Laboratory for Rural Research.Private Bag.P.O.Wembley.Western Australia 6014) 1997畜牧与饲料科学1997,22,S1:3
19含高钙和维生素D的强化奶能有效提高健康的绝经后的中国女性体内的维生素D水平并减少骨吸收显示文摘目的钙摄入水平低以及体内维生素D不足是导致亚洲女性罹患骨质疏松的危险因素。此项研究的目的是评估高钙维生素D强化牛奶(HCM)对健康的中国绝经后妇女的体内维生素D状态和骨吸收标志物进行干预的影响。方法本试验对象为55岁以上,绝经至少5年的女性。共有124名女性进行了总体健康状况和骨密度检查筛选。63名女性被随机分为对照组和试验组,试验组在12w内每日饮用两次高钙/维生素D强化奶(含900 mg钙、96 mg镁、2.4 mg锌和6.4μg维生素D)。2组分别在试验开始、试验2 w、8 w和12 w时测量血矿物质、25(OH)维生素D3和Ⅰ型胶原C端肽(CTX)水平。结果对照组女性平均年龄为63±4.6岁,高钙强化奶(HCM)组女性平均年龄为62±3.8岁。所测得的每日钙摄入量的基线值为HCM组260~482 mg,对照组为252~692 mg。12 w后HCM组的平均身体质量指数(BMI)显著降低(P<0.05)。HCM组的血25(OH)维生素D3水平显著提高(33.13~39.49 nmol/L),而对照组则维持不变(29.27~28.21 nmol/L)。HCM组的血CTX水平在0 w和2 w之间下降了25%,并保持不变直至第12w。从第2w开始HCM组和对照组相比血CTX水平就出现了显著差异(P<0.001)。结论通过饮用含高钙和维生素D的强化奶(HCM),在2至4w内能显著提高中国绝经妇女体内维生素D水平,并减少骨吸收破坏。如果长期持续地饮用含高钙和维生素D的强化奶(HCM),能减少骨吸收和骨量丢失的风险,从而减少患骨质疏松和由此引起骨折的风险。Marlena C Kruger PengCheng Ha Joanne M Todd Barbara Kuhn-Sherlock Linda M Schollum Jiliang Ma George Qin Edith Lau 2013中国骨质疏松杂志2013,19,2:2
