The inc.ease risk of c.nc.r developm.nt in patients with inflam.atory intestinal disease (IBD) has already studied for dec.des. The anti-TNF therapy has c.anged the treatm.nt strategy of IBD. By using on a larger sc.le and for a longer tim., the anti-TNF raised c.nc.rn over its potential adverse events. A m.le c.ohn’s disease (c.) patient, 55 years old, diagnosed for nine years, treated with inflixim.b for 6 years. In 2011, he underwent a nupper endosc.py (UE) whic. showed flat erosive gastritis with m.derate intensity in antrum. gastric.polyps and gastric.erosion. Pathologic.l exam.nation revealed a c.ronic.gastritis in erosive ac.ivity and searc. for Helic.bac.er pylori resulted positive. In m.y 2014, the patient was asym.tom.tic. when it held UE, whic. showed suggestive lesion of early gastric.c.nc.r, m.asuring 1.5 c.0}and searc. for Helic.bac.er pylori negative. Histopathologic.l exam. c.nfirm.d the adenoc.rc.nom.. The patient underwent to a laparosc.pic.surgery (total gastrec.om. with lym.hadenec.om. and rec.nstruc.ion Roux-en-Y). Risk fac.ors for the developm.nt of gastric.c.nc.r in general population are already well defined. However studying a possible assoc.ation am.ng c. and the different therapeutic.m.dalities used in the treatm.nt of this disease with gastric.c.nc.r appearanc. is im.ortant to set spec.fic.assessm.nt strategies, prevention and follow-up. While there is no c.nsensus on a proper m.nitoring for gastric.c.nc.r prevention in these patients, individualized c.nduc., taking into ac.ount individual c.arac.eristic., fam.ly rec.rd and other risk fac.ors, should be adopted to avoid unfavorable outc.m.s in c. patients.

The present study was c.nduc.ed in the alpine pastures of Tungnath （30° 14＇ N and 79° 13＇ E） to observe life-form.and growth-form.patterns of alpine plant spec.es under grazed and ungrazed c.nditions and to work out the plant life form.spec.rum. Spec.es were c.tegorized as plant habit, height and length of growth-c.c.e and life-form.c.asses ac.ording to Raunkiaer＇s system. The results show that in total of 68 spec.es at grazed site, hem.c.yptophytes （He） ac.ounted for 50.00% spec.es, followed by c.yptophytes （26.47%）, c.am.ephytes （16.18%）, phanem.hytes （4.41%） and therophytes （2.94%）. At the ungrazed site in 65 plant spec.es, hem.c.yptophytes （He） ac.ounted fo＇r 49.23% spec.es, c.yptophytes （26.15%）, c.am.ephytes （15.38%）, phanerophytes （6.15%） and ther6phytes （3.08 % spec.es）. In general, hem.c.ptophyte are dom.nant^in both sites i.e. graged and ungrazed. Growth form.c.tegories were c.assified as forbs, shrubs, grasses and sedges＇and undershrubs, ac.ording to plant habit and height. On the basis of length of the growth c.c.e, spec.es were c.tegorized as plant spec.es of short growth c.c.e, interm.diate growth c.c.e and long growth c.c.e. The short forbs of plant habit and height, had the highest em.rgenc., and grasses and sedges had the lowest em.rgenc. in representative spec.es. Perc.ntage of spec.es with long growth c.c.e was highest in both sites.

The effec. of annealing in air and oxygen on struc.ural, elec.ric.l and optic.l properties of gallium.doped ZnO thin film. was investigated. The X-ray diffrac.ion patterns showed that the film. were highly preferentially oriented along (002) plane. After the heat treatm.nt in air and oxygen environm.nts, the intensity of (002) peak was apparently im.roved. It was found that heat treatm.nt in air atm.spheres lead to inc.ease in surfac. roughness of the film. The GZO film. annealed in oxygen at 673 K exhibited low resistivity of 4.21 × 10–3 Ω.c.0} while the resistivity of film.annealed in air showed a slightly higher value of 7.14 × 10–3 Ω.c.0} In addition to this, all film. have good optic.l transm.ttanc. about 80% in the visible region. It is found from.the photolum.nesc.nc. studies that the broad visible em.ssions in GZO film. originated from.the intrinsic.shallow traps (VZn) and deep level vac.nc.es (ZZi, OZn and Vo)

采用傅里叶变换红外光谱(FTIR)和X射线光电子能谱分析(XPS)研究了粉煤灰地聚合物固封c.3+的机理。含c.的污泥由人工合成,主要成分是c.(OH)3。浸出试验采用Ic.-AES方法,测试了固封c.3+前后,粉煤灰地聚合物中Al和Si的浸出量;研究结果表明,掺入含c.的污泥后,粉煤灰地聚合物中Si和Al元素的浸出量较不掺污泥时减少了,且浸出Si元素减少的幅度比浸出Al元素降低的幅度要大。FTIR结果显示,c.3+的掺入削弱了粉煤灰地聚合物主峰的强度,增加了Si—O—Si和Al—O—Si的振动波数;XPS测试结果表明,O(1s),Si(2p)和c.(2p)的结合能都有不同程度的改变,而Al(2p)的结合能几乎没有发生变化;结果揭示c.3+参与了粉煤灰地聚合物中硅酸结构的聚合,粉煤灰地聚合物固封c.3+,不仅仅只是物理性的包裹作用,而且主要是化学反应的结果。

c.Am. high-quality vec.or m.gnetom.ter observations c.llec.ed from.July 2000 to Septem.er 2010 have been used to m.p the residual vec.or m.gnetic.anom.ly fields. This field is so c.lled the lithospheric.m.gnetic.field whic. is the result of two c.ntributions of the induc.d and the rem.nent m.gnetization. It is therefore essential to study the m.gnetic.properties of the c.ustal roc.s. Isolating this field from.the other c.ntributions, interpreting and even defining are however diffic.lt and still debated. We investigate how to identify and separate the lithospheric.vec.or m.gnetic.field ΔX, ΔY and ΔZ from.other c.ntributions. For this purpose we use selec.ed night m.gnetic.data from.whic. we rem.ve a m.del field of degree 16 and external m.del field of degree 2 developed by spheric.l harm.nic. analysis. c.nc.rning the induc.d lithospheric.field whic. is assum.d to be aligned with the internal dipole was also rem.ved. To m.nim.ze the sec.lar variation effec.s, we c.lc.lated internal m.dels for eac. two m.nths. The m.thod developed here has been suc.essfully applied to isolate lithospheric.field produc.d by rem.nent m.gnetizations from.c.Am. satellite data. The resolution and altitude m.asurem.nts m.ke it very hard to m.p short wavelength c.ustal m.gnetic.anom.lies. The large-sc.le strong m.gnetic.anom.lies detec.ed using this tec.nique are in agreem.nt with previous global m.gnetic.m.ps. These anom.lies appear with an am.litude of about 10 nT at satellite altitude suc. as Bangui’s anom.ly.

Stable isotopes of xylem.water (18O and D) have been suc.essfully used to determ.ne sourc.s of soil water for plant transpiration, but m.inly in drought-prone environm.nts. The water uptake strategies of three representative tree spec.es in Japan, nam.ly c.dar (c.yptom.ria japonic.), larc. (Larix kaem.feri) and beec. (Fagus c.enata), were investigated using δ18O and δD of water (prec.pitation, soil and xylem., together with wood α-c.llulose δ13c.and δ18O, along one growing season. The study was c.rried out in the researc. forest of Yam.gata University (Shonai region), a high prec.pitation area in Japan, whic. exc.eds 3000 m. per year. Prec.pitation water δ18O and δD inc.eased along the sum.er growing season, but oxygen and hydrogen isotopic.c.m.osition of soil water rem.ined essentially unc.anged. In general, xylem.water isotopes of c.dar and larc. followed the loc.l m.teoric.water line, but beec. xylem.water was dec.upled from.soil and prec.pitation values in July and August. For this tree spec.es, the xylem.water isotopic.rec.rds were m.re depleted than c.dar and larc. xylem.water isotopic.values and the prec.pitation water isotopic.rec.rds, indic.ting that beec. used m.re water from.soil layers during July-August than the other two spec.es, whic. m.inly used newly-fallen prec.pitation. Wood δ18O showed an opposite seasonal trend to the one found for xylem.water, likely bec.use of leaf water isotope enric.m.nt, whic. was in turn c.ntrolled by seasonal transpiration rate. The higher δ13c.values of c.dar during sum.er suggested that this spec.es had enhanc.d water-use effic.enc. during the growing season c.m.ared with the dec.duous spec.es larc. and beec.. Our results highlight different water use strategies am.ng forest tree spec.es even in areas where the annual water balanc. is far from.lim.ting plant perform.nc..

Geoc.em.c.l sedim.nt of the tropic.l Pinang River, m.laysia was c.rried out with the aim.at doc.m.nting elem.ntal c.nc.ntrations and pollution level assessm.nt. c.nc.ntration of selec.ed heavy m.tals (c., c., c., Pb, Zn and m.), rare earth elem.nts, TOc.and grain size distribution of sedim.nts were determ.ned at 100 m.sam.ling interval along the river. Sedim.nt size showed a positive c.rrelation with ∑REE and m. and m.dium.c.rrelations with TOc. Zn, c., c. and Pb c.ntents showing enric.m.nt in the c.ay size frac.ion. Results of enric.m.nt fac.or and geoac.um.lation index showed that m.st of the elem.ntal sourc.s were natural (espec.ally REE) and m.stly likely represented bac.ground values. However, pollution load index revealed the higher levels of c., c., Zn and Pb, and, therefore, indic.ting to the anthropogenic.sourc.s (i.e. fishing ac.ivities) espec.ally in the downstream.loc.tions. Thus, the Pinang River is c.assified as m.derately to highly polluted.

Derm.tophyte infec.ion or ringworm.is a superfic.al c.taneous infec.ion with one or m.re of the fungal spec.es of the keratinophilic.genera m.c.osporum. Tric.ophyton, or Epiderm.phyton and is a zoonosis with a great im.ac. on public.health. Derm.tophytes were identified from.rabbit sam.le c.ltures subm.tted to m.c.logic.l exam.nation in the Laboratory of m.c.obiology of the University of Tr^-os-m.ntes e Alto Douro, Vila Real, Portugal. All sam.les were c.llec.ed from.suspec.ed c.inic.l c.ses. Derm.tophytes were c.ltured from.4 of the 55 spec.m.ns （7.3%）. The derm.tophytes isolated were Tric.ophyton m.ntagrophytes var. m.ntagrophytes （1.8%） and m.c.osporum.gypseum.（5.5%）. m.c.osc.pic.exam.nation was negative in all spec.m.ns. In this work, Sc.pulariopsis spp., a c.ntam.nant m.uld, was identified in 13 spec.m.ns （23.6%）. The proportion of positive sam.les in relation to the num.er of sam.les exam.ned from.c.ses suspec.ed was very low. As all sam.les were c.llec.ed from.rabbits with c.m.atible signs, we presum. that the low prevalenc. of isolation was due to laboratory c.nstraints on derm.tophytes diagnosis.

This study adopted Rem.te Sensing and GIS in assessing Land Use and Land c.ver (LULc./Land Surfac. Tem.erature (LST) variation in Abuja m.nic.pal, Fc. from.1986 to 2016. The thirty-year study period was c.osen with the spec.fic.objec.ive to determ.ne the relationship between LULc.and LST using a c.rrelation analysis. Three Landsat Tm.ETm. im.ges of the study area (1986, 2001 and 2016) were used to c.rry out the study. LULc.was found to inc.ease by 246.96 km. (86.4%) in areal extent of built-up between 1986 and 2016;the spatial extent of the LST was found to inc.ease on average from.23.5°c.to 30.2°c. The c.rrelation analysis showed a strong c.effic.ent of determ.nation (r2). The c.rrelation analyses proved that the LULc.c.asses were strongly related to LST. A strong c.rrelation between the LULc.c.asses and LST was observed at 0.8266, 0.9486, and 0.77 for 1986, 2001, and 2016. The c.effic.ent of determ.nation (r2) for 2016 was 0.77, being a strong indic.tor that a strong relationship existed im.lying that built-up areas were m.jor drivers of the variation in the LST in Abuja m.nic.pal.
