Direct peroral cholangioscopy using an ultraslim upper endoscope for biliary lesions

引用

Hepatobiliary & Pancreatic Diseases International 2014年第1期13卷 60-64页

作者： Shigefumi Omuta Iruru Maetani takeo Ukita Tomoko Nambu Katsushige Gon Hiroaki Shigoka Yoshinori Saigusa Michihiro Saito Division of Gastroenterology Department of Internal Medicine Toho University Ohashi Medical Center

BACKGROUND: The development of direct peroral cholangioscopy(DPOC) using an ultraslim endoscope simplifies biliary cannulation. The conventional techniques are cumbersome to perform and require advanced skills. The recent introduction of the guidewires and balloons has improved the therapeutic outcomes. Here we describe an effective and easier method for performing DPOC using an ultraslim upper endoscope. METHODS: Indications for DPOC were the presence of stones on follow-up of patients who had previously undergone complete sphincteroplasty, including endoscopic sphincterotomy or endoscopic papillary large balloon dilatation. Fifteen patients underwent DPOC. An ultraslim endoscope was inserted perorally and was advanced into the major papilla. The ampulla of Vater was visualized by retroflexing the endoscope in the distal second portion of the duodenum, and then DPOC was performed using a wire-guided cannulation technique with an anchored intraductal balloon catheter. RESULTS: One patient failed in the treatment due to looping of the endoscope in the fornix of the stomach. Fourteen(93.3%) were successfully treated with our modified DPOC technique. Only one patient(6.7%) experienced an adverse event(pancreatitis) who responded well to conservative management. Residual stones of the common bile duct were completely removed in 3 patients. CONCLUSION: The modified method of DPOC is simple, safe and easy to access the bile duct.

Low-Density Co-Inoculation with Bradyrhizobium japonicum SAY3-7 and Streptomyces griseoflavus P4 Promotes Plant Growth and Nitrogen Fixation in Soybean Cultivars

引用

Inoculation density has a marked effect on nodulation and N fixation in soybean (Glycine max L.). Therefore, we conducted this study to determine the optimal inoculation density of Bradyhizobium japonicum SAY3-7 (SAY3-7) and Streptomyces griseoflavus P4 (P4) for plant growth, nodulation, and N fixation, and to investigate the effect of co-inoculation on selected soybean cultivars, using the optimal inoculation density. Nitrogen fixation, in terms of an acetylene reduction activity value, was measured using a flame ionization gas chromatograph. In this study, low-density single inoculation with P4 (105 or 106 cells mL-1) was associated with the highest plant biomass, compared with normal- and high-density single inoculation with P4 (107 or 108 cells mL-1). Moreover, low-density single or co-inoculations with SAY3-7 and/or P4 produced the highest nodule biomass and highest nitrogenase activity, compared with single or dual inoculation at other inoculation densities. Therefore, we evaluated low-density co-inoculation with P4 and SAY3-7, at the rate of 105 cells mL-1, on selected soybean cultivars. Low-density co-inoculation increased the plant biomass, compared with un-inoculated plants. The effects of single and co-inoculation on nodulation did not differ significantly for any of the cultivars, except “Yezin-9” in the first experiment and “Shan Seine” in the second experiment. Low-density inoculation with both bacteria increased N fixation by 15% - 75% for seven of the cultivars in the first experiment and by 15% - 39% for three of the cultivars in the second experiment, compared with single inoculation with SAY3-7. Based on the overall results, we concluded that low-density co-inoculation with P4 and SAY3-7 gave improved plant growth and N fixation.

作者： Kewei DING takeo KAYABA College of Animal Science and Technology Northeast Agricultural University Faculty of Agriculture Yamagata University

[Objective] This study aimed to estimate the genetic parameters for milk yield, fat percentage, fat yield and age at first freshening of Chinese Holsteins first lactation cows in Heilongjiang under frigid-temperature and temperature zone. [Method] Records of yield and reproduction from 8 868 Chinese Holstein first lacta- tion cows from 21 herds were utilized to evaluate genetic parameters for Hei- Iongjiangs＇ Chinese Holsteins. Restricted maximum likelihood （REML） method was used with an animal model. [Result] The heritabilities were 0.16 to 0.34 for yields and fat percentage, 0.38 for reproduction （age at the first freshening）, which were similar to estimates for temperate areas from similar methods, except for constituent percentage. Also, the estimates of genetic correlation were high between milk yield and fat yield （0.97）, but were low between milk yield and fat percentage （-0.24）, age at the first freshening （-0.29） and generally antagonistic. [Conclusion] Thus, es- timates of genetic parameters in this frigid and frigid-temperate environment did not differ appreciably from those that occur in temperate dairy areas.

Low-Density Co-Inoculation of Myanmar Bradyrhizobium yuanmingenseMAS34 and Streptomyces griseoflavusP4 to Enhance Symbiosis and Seed Yield in Soybean Varieties

引用

American Journal of Plant Sciences 2013年第9期4卷 1879-1892页

作者： Khin Myat Soe takeo Yamakawa Plant Nutrition Laboratory Graduate School of Bioresource and Bioenvironmental Sciences Faculty of Agriculture Kyushu University Fukuoka Japan Plant Nutrition Laboratroy Division of Molecular Biosciences Department of Biosciences & Biotechnology Faculty of Agriculture Kyushu University Fukuoka Japan.

This study examined whether low-density co-inoculation of Myanmar Bradyrhizobium yuanmingense strain MAS34 and Streptomyces griseoflavus P4 would enhance nodulation, N2 fixation, and seed yield in two soybean varieties. A field experiment was conducted during the July to November 2012 growing season at Kyushu University Farm, Japan, using a split-plot design with three replications and the following four treatments: T1, an uninoculated treatment with peat moss (uninoculated);T2, a single inoculation with S. griseoflavus P4 (P4);T3, a single inoculation of B. yuanmingense MAS34 (MAS34);and T4, a dual inoculation of P4 with MAS34 (P4 + MAS34). Two varieties of soybean, Yezin-3 (Rj4) and Yezin-6 (non-Rj), were used. The N2 fixation activity of soybean was evaluated by the relative ureide method using xylem solute from root bled sap at the early pod-fill stage (R3.5). Dry matter production, N2 fixation, and seed yield were significantly (P 0.01) different between the inoculated treatments. The effect of variety was also significant (P 0.05) for nodule dry weight at the V6 stage, percentage of N derived from the atmosphere at the R3.5 stage, and seed yield at the maturity stage. The number of nodules on the tap roots was significantly higher in Yezin-3 than in Yezin-6. The single inoculation of P4 did not have a significant effect on dry matter production, N2 fixation, and seed yield in either soybean variety. The dry matter production, relative ureide index, percentage of N derived from the atmosphere, and seed yield were significantly (P 0.01) enhanced by a single inoculation of MAS34 in Yezin-3 and by dual inoculation of P4 + MAS34 in Yezin-6. These results indicate that low inoculum concentrations (105 cells seed-1) increase N2 fixation and seed yield in these soybean varieties under open field conditions. Myanmar B. yuanmingense MAS34 and S. griseoflavus P4 are expected to be useful biofertilizers for soybean production.

Incompatible Nodulation of Bradyrhizobium elkaniiStrains BLY3-8 and BLY6-1 with Rj3 Gene-Harboring Soybean Cultivars

引用

American Journal of Plant Sciences 2017年第2期8卷 178-190页

Bradyrhizobia are known symbiotic partners of soybean. However, some soybean cultivars restrict nodulation by some Bradyrhizobium bacterial strains. These restrictions are related to compatibility between the Rj genes of soybean cultivars and nodulation types of inoculated bacteria. The objective of this study was to determine nodulation incompatibility of Type B strains with Rj3 soybean cultivars. Newly isolated B. elkanii strains BLY3-8 and BLY6-1 from Myanmar and specific strain Bradyrhizobium elkanii USDA33, which are incompatible with Rj3 soybean cultivars, and B. japonicum USDA110 were used as inoculants to check compatibility or incompatibility with Rj3 soybean cultivars. Nitrogen fixation activity was measured by the acetylene reduction method. Ethylene concentration (reduction of acetylene) was determined by flame ionization gas chromatography. According to the inoculation test results, USDA110 was compatible with all soybean cultivars because it formed effective nodules (Figure S1 in Appendix) and possessed nitrogenase activity. Similarly, B. elkanii strains BLY3-8, BLY6-1, and USDA33 were highly compatible with non-Rj and Rj4-gene harboring soybean cultivars because they had the ability to form functional nodules and possessed nitrogenase activity. Inversely, BLY3-8, BLY6-1, and USDA33 were incompatible with Rj3 soybean cultivars because they produced ineffective nodules. Consequently, the ratio of ineffective nodule number to total nodule number was >0.5. Therefore, nodule formation by the newly isolated B. elkanii strains BLY3-8 and BLY6-1 was restricted by the Rj3 soybean cultivars potentially making them useful as specific strains to detect the Rj3 gene in soybean cultivars.
