| 1 | Dissimilatory Fe(Ⅲ) reduction characteristics of paddy soil extract cultures treated with glucose or fatty acids显示文摘Dissimilatory Fe(Ⅲ) reduction is a universal process with irreplaceable biological and environmental importance in anoxic environments. Our knowledge about Fe(Ⅲ) reduction predominantly comes from pure cultures of dissimilatory Fe(Ⅲ) reducing bacteria (DFRB). The objective of this study was to compare the effects of glucose and a selection of short organic acids (citrate, succinate, pyruvate, propionate, acetate, and formate) on Fe(Ⅲ) reduction via the anaerobic culture of three paddy soil solutions with Fe(OH)3 as the sole electron acceptor. The results showed significant differences in Fe(Ⅲ) reduction among the three paddy soil solutions and substrate types. Bacteria from the Sichuan paddy soil responded quickly to substrate supply and showed higher Fe(Ⅲ) reducing activity than the other two soil types. Bacteria in the Jiangxi paddy soil culture solution could not use propionate as a source of electrons for Fe(Ⅲ) reduction. Similarly, bacteria in the Jilin paddy soil culture could not use succinate effectively. Pyruvate was readily used by cultures from all three paddy soil solutions, thus indicating that there were some similarities in substrate utilization by bacteria for Fe(Ⅲ) reduction. The use of glucose and citrate as substrate for dissimilatory Fe(Ⅲ) reduction indicates important ecological implications for this type of anoxic respiration. | HE Jiangzhou1,2, QU Dong1, 1.

| 2 | The EST Analysis of A Suppressive Subtraction cDNA Library of Chinese Wild Vitis pseudoreticulata Inoculated with Uncinula necator显示文摘Uncinula necator is a worldwide serious fungus disease causing annual heavy lost on grapevine production. In order to get more informations on defense related EST sequences and help breeding program, we constructed and characterized a suppression subtractive hybridization cDNA library with artificially inoculated leaves and control Chinese wild Vitis pseudoreticulata clone Baihe-35-1, which is highly resistant to powdery mildew. In the library, the length of 58 EST fragments known as putative functions varied from 130 to 800 bp, and 60% of the ESTs exhibited high similarity to known sequences in database of GenBank with BLASTX analysis. These genes were involved in stress/defense response, detoxification, signal transduction, disease defense, and etc., and 14 ESTs remained unknown or hypothetical proteins, which may be new genes. The experiment provided an important basis for studying the disease-resistance mechanism and obtaining the genes for the aim of improving grapevine powdery mildew resistance. | SHI Jiang-li, WANG Yue-jin, ZHU Zi-guo and ZHANG Chao-hong Key Laboratory of Horticultural Plant Germplasm Utilization in Northwest China, Ministry of Agriculture/Shaanxi Key Laboratory of Molecular Biology for Agriculture/College of Horticulture, Northwest A&F University, Yangling 712100, P.R.China | 2010 | Agricultural Sciences in China2010，9，2： | 5 |
| 3 | 光激酶C基因突变导致的大头精子畸形是阿尔及利亚男性不育症的最常见遗传因素显示文摘克氏综合征和Y染色体微缺失是过去针对男性不育症仅有的两项基因检测分析技术。北非男性经常出现两种罕见的畸形精子症:大头和圆头精子畸形,推荐进行AURKC和DPYl9L2基因检测。对阿尔及利亚男性不育患者进行以上基因检测,评估两种畸形精子症的患病率,并与克氏综合征和Y染色体微缺失的频率进行比较。我们对阿尔及利亚君士坦丁市的IbnRochd医院辅助生殖中心进行不育症咨询的599名患者进行了回顾性研究,其中404人存在精液参数异常现象。14人和7人分别患有典型的大头精子畸形或圆头精子畸形,进而对这些患者进行了AURKC和DPYl9L2基因分析显示,11名大头精子畸形患者存在4URKC基因突变(79%),相当于所有精液异常人群的2.7%。而5名圆头精子畸形患者,相当于1.2%的不育症患者,均存在DPYl9L2基因缺失。通过比较,我们预测该人群中克氏综合症和Y染色体微缺失的患病率分别是1.6%和0.23%。我们的研究表明AURKC基因突变较克氏综合症更常见,它是导致北非男性不育的主要遗传因素。此外,本文也预测了AURKC和DP"觋2基因缺陷发生率分别是Y染色体微缺失发生率的10倍和5倍。 | Leyla Ounis Abdelali Zoghmar Charles Coutton Leila Rouabah Maroua Hachemil Delphine Martinez Guillaume Martinez Ines Bellil Douadi Khelifi Christophe Arnoult Julien Faure Sebti Benbouhedja Abdelkader Rouabah Pierre F Ray | 2015 | Asian Journal of Andrology2015，17，1： | 5 |
| 4 | Conduction properties of condensed lanthanum phosphates:La(PO_3)_3 and LaP_5O_(14)显示文摘Single crystals of LaP3O9·3H2O were prepared using a classical method of aqueous chemistry whereas those of the ultraphosphate LaP5O14 were obtained by flux method.Thermal treatment of LaP3O9·3H2O up to 700 °C allowed us to obtain the lanthanum polyphosphate La(PO3)3.The conductivity as well as the vibrational study of the lanthanum ultraphosphate and polyphosphate were analysed in order to explain the mechanism of conduction.Activation energies of 0.45 and 0.84 eV,deduced from the Arrhenius relation,were respectively found for the polyphosphate and the ultraphosphate.Taking into account the structural features of these materials we linked the origin of their electrical properties to the incorporation of atmospheric humidity.Thus,it was a proton conduction phenomenon which took place as a result of the establishment of hydrogen bonds as well as the reorganisation of water molecules already incorporated into these structures.Referring to the Grotthuss mechanism,a proton transfer model inside the polyphosphate's structure was suggested. | Ines Hammas Karima Horchani-Naifer Mokhtar Férid | 2010 | Journal of Rare Earths2010，28，3： | 3 |
| 5 | Is the schatzki ring a unique esophageal entity?显示文摘AIM:To study,whether the association of Schatzki rings with other esophageal disorders support one of the theories about its etiology.METHODS:From 1987 until 2007,all patients with newly diagnosed symptomatic Schatzki rings (SRs) were prospectively registered and followed.All of them underwent structured interviews with regards to clinical symptoms,as well as endoscopic and/or radiographic examinations.Endoscopic and radiographic studies determined the presence of an SR and additional morphological abnormalities.RESULTS:One hundred and sixty-seven patients (125 male,42 female) with a mean age of 57.1±14.6 years were studied.All patients complained of intermittent dysphagia for solid food and 113 (79.6%) patients had a history of food impaction.Patients experienced symptoms for a mean of 4.7±5.2 years before diagnosis.Only in 23.4% of the 64 patients who had endoscopic and/or radiological examinations before their first presentation to our clinic,was the SR previously diagnosed.At presentation,the mean ring diameter was 13.9±4.97 mm.One hundred and sixty-two (97%) patients showed a sliding hiatal hernia.Erosive reflux esophagitis was found in 47 (28.1%) patients.Twenty-six (15.6%) of 167 patients showed single or multiple esophageal webs;five (3.0%) patients exhibited eosinophilic esophagitis;and four (2.4%) had esophageal diverticula.Four (7%) of 57 patients undergoing esophageal manometry had nonspecific esophageal motility disorders.CONCLUSION:Schatzki rings are frequently associated with additional esophageal disorders,which support the assumption of a multifactorial etiology.Despite typical symptoms,SRs might be overlooked. | Michaela Müller Ines Gockel Philip Hedwig Alexander J Eckardt Kathrin Kuhr Jochem Knig Volker F Eckardt | 2011 | World Journal of Gastroenterology2011，17，23： | 2 |
