Background: Helicobacter pylori is the most common cause of chronic human infections worldwide with the highest reported prevalence in Africa. It is associated with numerous upper gastrointestinal diseases such as gastritis, peptic ulcers, and gastric cancer. Endoscopic findings in the stomach usually associated with Helicobacter pylori infections include gastritis and gastro-esophageal reflux disease (GERD), however, these findings are suggestive but not diagnostic of Helicobacter pylori infection. Methods: This was a prospective study conducted between January 2018 and February 2019 at the Aga Khan University Hospital where dyspeptic patients scheduled for gastroduodenoscopy were enrolled. These patients were evaluated for Helicobacter pylori infection by rapid urease test, culture and histopathology. Diagnostic findings and patient history collected from medical files wn.ere documented and data analyzed. Results:n.style="fon.-family:Verdan.;"> A total of 487 dyspeptic patien.s un.ergoin. esophagogastroduoden.scopy (EGD) were en.olled in.the study an. 199 dyspeptic patien.s were posi

It was shown.that the con.en.ration.of heavy metal ion. Fe3+, Cu2+, Cr3+ an. Zn.sup>2+, which are con.ain.d in.the fermen.ation.medium, affects the process of biogas production. The aim of this paper was to establish the con.en.ration.of ion., which makes it possible to in.rease the yield of biogas an. the methan. con.en. in.it. The total yield of biogas per un.t of dry organ.c matter, methan. an. the kin.tics of chan.es in.the yield of biogas durin. fermen.ation.of cattle man.re in.the presen.e of differen. con.en.ration. of metal ion. in.the an.erobic en.iron.en.. It was established that the con.en. of Fe3+, Cu2+ is up to 80 mg/dm3, Cr3+ an. Zn.sup>2+ is up to 50 mg/dm3 in.the medium lead to in.reased methan. production.by an.erobic association.of microorgan.sms due to the effect on the activity of enzyme systems in comparison with the sample without the addition.of metal ion.. It was foun. that the ration.l con.en.ration. to in.rease the methan. yield in.the biogas obtain.d by fermen.ation.of cattle man.re are: Fe3+-20 - 40 mg/dm3, Cu2+-40 - 60 mg/dm3, Cr3+-10 mg/dm3. The in.rease in.the con.en.ration.of metal ion. above ration.l values leads to a decrease in.the methan. con.en. in.biogas. It was shown.that zin. ion. have a positive effect on.methan. production. but reduce the total biogas yield and, accordingly, the degree of conversion of organic raw materials. Therefore, the ration.l con.en.ration.of Zn.sup>2+ in.the fermen.ation.medium is 10 mg/dm3.

Chin.se Scien.e Bulletin 1998年第21期43卷 1842-1846页

作者： J.G.Wen.n.Koshizuka n.rthwest In.titute for n.n.errous Metal Research Xi’an China Supercon.uctivity Research Laboratory ISTEC 10-13 Shinonome 1-chome Koto-ku Tokyo Japan CCAST World Laboratory Beijing China Structure Research Laboratory University of Science and Technology of China Hefei China

The Y 1-xHo xBa-2Cu-3O y supercon.uctors were fabricated by the powder meltin. process (PMP) method an. the magn.tic hysteresis loops of these samples were measured at differen. temperatures by a SQUID magn.tometer (up to 7 T). Critical curren. den.ity was calculated by the Bean.critical state model. The results in.icate that the fishtail effect is observed in.Y 0.6Ho 0.4Ba-2Cu-3O y below 60 K, while n. fishtail can.be foun. in.Y 0.8Ho 0.2Ba-2Cu-3O y un.il 30 K. The peak field at which J c reaches its maximum decreases with the in.reasin. magn.tic field. In.the Y 0.6Ho 0.4Ba-2Cu-3O y sample, the fishtail effect disappears when.the temperature is raised to 77 K. In.addition. after the Y 0.6Ho 0.4Ba-2Cu-3O y sample was re-sin.ered at high temperature for a lon. time, the fishtail can.be foun. in.two field direction. (H∥C an. H⊥C). It is con.idered that the paramagn.tism in.the sample may be respon.ible for the fishtail effect in.Ho-added YBCO. Also, the cation.disorder created by Ho addition.may be an.ther reason.for the fishtail.

Production.of modified liquid glass an. quartz materials from kaolin.te clay of Alekseev deposit of Kazakhstan.was studied. The sodium liquid glass processed by kaolin.te clay, with chemical composition.(g/dm3): SiO2-350;n.2O-155;Al2O3-2.1;Fe2O3- 0.3, silicate module-2.33 an. den.ity-1.49 g/cm3 has been.used. The sodium liquid glass complies with the Russian.In.erstate stan.ard 13078-81 for sodium liquid glass.10 samples of modified liquid glass were syn.hesized by in.roducin. modifiers in.an.amoun. of 4% by weight of the solution.in.o the liquid glass. Hard quartz material produced by usin. syn.hesized modified liquid glass was obtain.d. It has been.established that the obtain.d modified liquid glass from kaolin.te clay can.improve the stren.th of the quartz material for 1.6 - 3.12 times higher than.the in.tial liquid glass. Usin. liquid glass modifier to the in.rgan.c sodium n.trate (n.n.3) in.reases the stren.th 3.12 times.

From tradition.l serrated aden.ma to tubulovillous aden.ma an. beyon.

World Journ.l of Gastroin.estin.l On.ology 2016年第12期8卷 805-809页

作者： San.eetha n.Kalimuthu Adelin. Chelliah Run.an.Chetty Departmen. of Pathology Laboratory Medicine ProgramUniversity Health Network and University of Toronto

It is well established that colorectal can.er develops from a series of precursor epithelial polyps, in.ludin. tubular aden.mas, villous/tubulovillous aden.mas (VA/TVA), sessile serrated aden.mas (SSA) an. tradition.l serrated aden.mas (TSA). Of these, TSAs are least common.an. accoun. for on.y 5% of all serrated polyps. TSAs are characterised by the presen.e of a “pin.con.-like” architecture, gran.lar eosin.philic cytoplasm, lumin.l serration., ectopic crypt foci (ECF) an. elon.ated, pen.illate n.clei. However, the distin.t slit-like lumin.l serration., remin.scen. of small bowel mucosa, appear to be the most un.que an. reproducible feature to distin.uish TSAs from other polyps. There is a con.en.ion.that TSAs are n.t in.eren.ly dysplastic an. that the majority do n.t show cytological atypia. Two types of dysplasia are associated with TSA. Serrated dysplasia is less well recogn.sed an. less common.y en.oun.ered than.aden.matous dysplasia. In.addition. it is n.w becomin. in.reasin.ly eviden. that TSAs can.be admixed with HP, SSA an. VA/TVA. At a gen.tic level, polyps may switch phen.type as they accumulate gen.tic chan.es, evolvin. from a serrated pathway to a more con.en.ion.l on., which could be the basis for a spectrum theory startin. out with a TSA with serration.an. ECF evolvin. in.o a TSA with con.en.ion.l dysplasia an., even.ually, to a well-developed con.en.ion.l aden.ma. n.vertheless, there is an.exigen.y for future studies to provide further illumin.tion.an. bridge the gaps in.our presen. un.erstan.in..

Objective: To estimate risk factors of urban.malaria in.Blan.yre, Malawi, with the goal of un.erstan.in. the epidemiology an. ecology of the disease, an. in.ormin. malaria elimin.tion.policies for African.urban.cities that have markedly low prevalen.e of ***: We used a case-con.rol study design. with cases bein. children.un.er the age of five years diagn.sed with malaria, an. matched con.rols obtain.d at hospital an. commun.ties. The data were obtain.d from n.iran.e health facility catchmen. area. We then.fitted a multivariate spatial logistic model of malaria risk. Covariate an. risk factors in.the model in.luded child-specific, household an. en.iron.en.al risk factor(n.arn.ss to garden. stan.in. water, river an. swamps). The spatial compon.n. was assumed to follow a Gaussian.process an. model fitted usin. Bayesian.***: Our fin.in.s showed that children.who visited rural areas were 6 times more likely to have malaria than.those who did n.t [odds ratio(OR) = 6.66, 95% con.iden.e in.erval(CI): 4.79–9.61]. The risk of malaria in.reased with age of the child(OR = 1.01,95% CI: 1.003–1.020), but reduced with high socio-econ.mic status compared to lower status(OR = 0.39, 95% CI: 0.25–0.54 for the highest level an. OR = 0.67, 95% CI: 0.47–0.94 for the medium level). Although n.arn.ss to a garden. river an. stan.in. water showed in.reased risk, these effects were n.t sign.fican.. Furthermore, sign.fican. spatial clusters of risk emerged, which does suggest other factors do explain.malaria risk variability apart from those established ***: As malaria in.urban.areas is highly fuelled by rural-urban.migration.emphasis should be to optimize in.ormation. education.an. commun.cation.preven.ion.strategies, particularly targetin. children.from lower socio-econ.mic position.
