1Probiotic effects on intestinal fermentation patterns in patients with irritable bowel syndrome显示文摘AIM: To determine whether Lactobacillus casei strain Shirota (Yakult ) can alter small intestinal bacterial overgrowth (SIBO), as tested by the lactulose breath test, and whether this is associated with changes in symptoms in irritable bowel syndrome (IBS). METHODS: 18 patients with IBS (Rome Ⅱ criteria), who showed an early rise in breath hydrogen with lactulose (ERBHAL), consumed 65 mL of Yakult daily for 6 wk. Lactulose breath test was repeated at the end of the treatment period. Symptoms were recorded daily using a 10 cm visual analogue scale. RESULTS: 14 patients completed the study, 9 (64%) had reversal of ERBHAL, with the median time of f irst rise in breath hydrogen increasing from 45 to 75 min (P = 0.03). There was no signifi cant improvement in the symptom score with probiotic therapy, except for wind (P=0.04). Patients commencing with at least moderate symptoms and who no longer had ERBHAL at the end of treatment, showed improvement in the overall symptoms scores [median fi nal score 5.3 (IQR3.9-5.9), 55% reduction; n=6] to a greater extent than those who had had persisting ERBHAL [final score 6.9 (5.0-7.0), 12% reduction; n = 5; P = 0.18]. CONCLUSION: Yakult is effective in altering fermentation patterns in the small bowel, consistent with reducing SIBO. The loss of ERBHAL was associated with reduced symptoms. The true interpretation of these fi ndings awaits a randomised, controlled trial.Jacqueline S Barrett Kim EK Canale Richard B Gearry Peter M Irving Peter R Gibson 2008World Journal of Gastroenterology2008,14,32:16
2Antibacterial activity of various leaf extracts of Merremia emarginata显示文摘Objective:To investigate the antibacterial activity and phytochemical screening of the aqueous.methanol and petroleum ether leaf extracts of Merremia emarginata(M.emarginata).Methods:The antibavterial activity of leaf extracts of M.emarginata were evaluated by agar well diffusion method against four selected bacterial species.Results:The presence of tannins,flavonoids,amino acids,starch,glycosides and carbohydrates in the different leaf extracts was established.The methanol extract was more effective against Baciilus cereus and Eseherkhia coli,whereas aqueous extract was more effective against Staphylococcus aureus and Pseudomonas aeruginosa.Condusions:The results in the present study suggest that M.emarginata leaf can be used in treating diseases caused by the tested organisms.EK Elumalai M Ramachandran T Thirumalai P Vinothkumar 2011Asian Pacific Journal of Tropical Biomedicine2011,1,5:8
3In Situ Etching for Total Control Over Axial and Radial Nanowire Growth显示文摘We report a method using in situ etching to decouple the axial from the radial nanowire growth pathway,independent of other growth parameters.Thereby a wide range of growth parameters can be explored to improve the nanowire properties without concern of tapering or excess structural defects formed during radial growth.We demonstrate the method using etching by HCl during InP nanowire growth.The improved crystal quality of etched nanowires is indicated by strongly enhanced photoluminescence as compared to reference nanowires obtained without etching.Magnus T.Borgström Jesper Wallentin Johanna Trägårdh Peter Ramvall Martin Ek LReine Wallenberg Lars Samuelson Knut Deppert 2010Nano Research2010,3,4:4
4Tensile and fracture properties of an Mg-RE-Zn alloy at elevated temperatures显示文摘Magnesium alloy EZ10(Mg-RE-Zn) was deformed in tension at temperatures from 20 up to 520 °C. A rapid decrease of the yield and tensile strength with temperature was observed at temperatures higher than 300 °C. On the other hand, ductility of samples rapidly increased in the same temperature range. Light microscopy and scanning electron microscopy was used to reveal the reason for these behaviours. Intermetallic particles in grain boundaries are responsible for excellent mechanical properties at lower temperatures. Diffusional processes occurring at temperatures higher than 300 °C significantly influenced the deformation mechanism as well as the fracture character.TROJANOVZuzanka DONI Tibor LUK Pavel PALEK Peter CHALUPOV Mária TILLOV Eva BASTOVANSKY Ronald 2014Journal of Rare Earths2014,32,6:3
5顽固性高血压与由心内容积决定的血管内液体潴留无关显示文摘顽固性高血压(refractory hypertension,RfHTN)是一种极端的抗高血压治疗失败的表现形式,定义为使用了包括长效噻嗪类和盐皮质激素受体拮抗剂在内的≥5种药时血压仍控制欠佳。RfHTN是难治性高血压(resistant hypertension,RHTN)的一个亚组,RHTN定义为使用≥3种降压药(包括利尿剂)后血压仍〉135/85mm Hg(1mm Hg=0.133kPa)。刘青 叶鹏 Velasco A Siddiqui M Kreps E Kolakalapudi P Dudenbostel T Arora G Judd EK Prabhu SD Lloyd SG Oparil S Calhoun DA 2018中华高血压杂志2018,26,7:2
