| 1 | Methane production and small intestinal bacterial overgrowth in children living in a slum显示文摘AIM:To analyze small intestinal bacterial overgrowth in school-aged children and the relationship between hydrogen and methane production in breath tests.METHODS:This transversal study included 85 children residing in a slum and 43 children from a private school,all aged between 6 and 10 years,in Osasco,Brazil.For characterization of the groups,data regarding the socioeconomic status and basic housing sanitary conditions were collected.Anthropometric data was obtained in children from both groups.All children completed the hydrogen(H 2) and methane(CH 4) breath test in order to assess small intestinal bacterial overgrowth(SIBO).SIBO was diagnosed when there was an increase in H 2 ≥ 20 ppm or CH 4 ≥ 10 ppm with regard to the fasting value until 60 min after lactulose ingestion.RESULTS:Children from the slum group had worse living conditions and lower nutritional indices than children from the private school.SIBO was found in 30.9%(26/84) of the children from the slum group and in 2.4%(1/41) from the private school group(P = 0.0007).Greater hydrogen production in the small intestine was observed in children from the slum group when compared to children from the private school(P = 0.007).A higher concentration of hydrogen in the small intestine(P < 0.001) and in the colon(P < 0.001) was observed among the children from the slum group with SIBO when compared to children from the slum group without SIBO.Methane production was observed in 63.1%(53/84) of the children from the slum group and in 19.5%(8/41) of the children from the private school group(P < 0.0001).Methane production was observed in 38/58(65.5%) of the children without SIBO and in 15/26(57.7%) of the children with SIBO from the slum.Colonic production of hydrogen was lower in methaneproducing children(P = 0.017).CONCLUSION:Children who live in inadequate environmental conditions are at risk of bacterial overgrowth and methane production.Hydrogen is a substrate for methane production in the colon. | Carolina Santos Mello Soraia Tahan Lígia Cristina FL Melli Mirian Silva do Carmo Rodrigues Ricardo Martin Pereira de Mello Isabel Cristina Affonso Scaletsky Mauro Batista de Morais | 2012 | World Journal of Gastroenterology2012，18，41： | 3 |

| 6 | Synthesis of Au-Cu Nano-Alloy from Monometallic Colloids by Simultaneous Pulsed Laser Targeting and Stirring显示文摘Experimental work has been focused on the formation of alloyed Au-Cu nanoparticles under simultaneous laser exposure and mechanical stirring of mixed monometallic colloids, here referred to as dual procedure. As a feed for the dual procedure, Au and Cu monometallic nanoparticle colloids have been using a laser ablation technique. To accomplish this, bulk targets were ablated with 1064 nm wavelength Nd: YAG laser in a pure acetone(99.99%) environment. Ultraviolet-visible optical absorption spectrometry, transmission electron microscopy, X-ray diffraction and X-ray fluorescence technique have been used to characterize the nanoparticles. It has been found that experimental conditions such as stirring and laser parameters strongly affect the synthesized particle properties, including the size, shape, composition and stability of the nanoparticles. Alloy nanoparticles containing 39% Au – 61% Cu have also been prepared in the same process, but in two forms of a homogeneous alloy and a core-shell structure. | Mansoureh Ganjali Monireh Ganjali Soraia Khoby Mohammad Ali Meshkot | 2011 | Nano-Micro Letters2011，3，4： | 1 |

| 19 | 甲醇-水二元混合物中Co(bpb)与叠氮离子反应的动力学研究(英文)显示文摘Co(bpb) [bpbH2is N,N′-o-phenylenebis(pyridine-2-carboxamide) ,C18H12N4O2] complex has active axial sites like a porphyrin complex. We studied the coordination of azide ion(N3-) to Co(bpb) in binary methanol-water mixtures by spectrophotometric method at the temperature range of 283-303 K. From the temperature dependence of the rate constant,activation parameters(Ea,ΔH,ΔS,and ΔG) were obtained. An isokinetic temperature at about 302 K was observed at which the formation rate of Co(bpb) -N3-was more or less independent of the solvent composition. The resulting ΔH against TΔS plot showed a good linear correlation,indicating the existence of enthalpy-entropy compensation in azide complexation process. Under optimum conditions and based on the absorbance of Co(bpb) -N3-produced through complex formation,a spectrophotometric method for the determination of N 3-in solution was developed. A linear relationship between the absorbance and N3-concentration was obtained in the range of(0.85-5.00) × 10-4 mol·L-1(3.6-21.0 μg·mL-1) . The detection limit was 2.5×10-5 mol·L-1(1.0 μg·mL-1) . The proposed method was applied to the determination of N3-anion in real water samples. | HASHEMI Javad ALIZADEH Naader MEGHDADI Soraia AMIRNASR Mehdi | 2009 | 物理化学学报2009，25，6： | 1 |
