| 1 | Early effects of oral administration of omeprazole and roxatidine on intragastric pH显示文摘Objective:The ideal medication for the treatment of acid-related diseases,e.g.,peptic ulcers,stress-related gastric bleeding,functional dyspepsia,and gastroesophageal reflux disease,should have a rapid onset of action to promote hemostasis and relieve the symptoms.The aim of our study was to investigate the inhibitory effects on gastric acid secretion of a single oral administration of a proton pump inhibitor,omeprazole 20 mg,and an H2-receptor antagonist,roxatidine 75 mg.Methods:Ten Helicobacter pylori-negative male subjects participated in this randomized,two-way crossover study.Intragastric pH was monitored continuously for 6 h after single oral administration of omeprazole 20 mg and roxatidine 75 mg.Each administration was separated by a 7-d washout period.Results:During the 6-h study period,the average pH after administration of roxatidine was higher than that after administration of omeprazole(median:4.45 vs.2.65;P=0.0367).Also during the 6-h study period,a longer duration of maintenance at pH above 2,5,and 6 was observed after administration of roxatidine 75 mg than after administration of omeprazole 20 mg(median:90.6% vs.55.2%,P=0.0284;43.7% vs.10.6%,P=0.0125;40.3% vs.3.3%,P=0.0125;respectively).Conclusions:In Helicobacter pylori-negative healthy male subjects,oral administration of roxatidine 75 mg increased the intragastric pH more rapidly than that of omeprazole 20 mg. | Hiroshi IIDA Shingo KATO Yusuke SEKINO Eiji SAKAI Takashi UCHIYAMA Hiroki ENDO Kunihiro HOSONO Yasunari SAKAMOTO Koji FUJITA Masato YONEDA Tomoko KOIDE Hirokazu TAKAHASHI Chikako TOKORO Ayumu GOTO Yasunobu ABE Noritoshi KOBAYASHI Kensuke KUBOTA Eiji GOTOH Shin MAEDA Atsushi NAKAJIMA Masahiko INAMORI | 2012 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2012，13，1： | 6 |
| 2 | characteristics of intestinal pseudo-obstruction in patients with mitochondrial diseases显示文摘AIM: To reveal the frequency, characteristics and prognosis of chronic intestinal pseudo-obstruction (CIP) in mitochondrial disease patients. METHODS: Between January 2000 and December 2010, 31 patients (13 males and 18 females) were di-agnosed with mitochondrial diseases at our hospital. We conducted a retrospective review of the patients' sex, subclass of mitochondrial disease, age at onset of mitochondrial disease, frequency of CIP and the age at its onset, and the duration of survival. The age at onset or at the first diagnosis of the disorder that led to the clinical suspicion of mitochondrial disease was also examined. RESULTS: Twenty patients were sub-classified with mitochondrial encephalopathy with lactic acidosis and stroke-like episodes (MELAS), 8 with chronic progressive external ophthalmoplegia (CPEO), and 3 with myoclonus epilepsy associated with ragged-red fibers (MERRF). Nine patients were diagnosed with CIP, 8 of the 20 (40.0%) patients with MELAS, 0 of the 8 (0.0%) patients with CPEO, and 1 of the 3 (33.3%) patients with MERRF. The median age (range) at the diagnosis and the median age at onset of mitochondrial disease were 40 (17-69) and 25 (12-63) years in patients with CIP, and 49 (17-81) and 40 (11-71) years in patients without CIP. During the survey period, 5 patients (4 patients with MELAS and 1 with CPEO) died. The cause of death was cardiomyopathy in 2 patients with MELAS, cerebral infarction in 1 patient with MELAS, epilepsy and aspiration pneumonia in 1 patient with MELAS, and multiple metastases from gastric cancer and aspiration pneumonia in 1 patient with CPEO. CONCLUSION: Patients with CIP tend to have disorders that are suspected to be related to mitochondrial diseases at younger ages than are patients without CIP. | Yusuke Sekino Masahiko Inamori Eiji Yamada Hidenori Ohkubo Eiji Sakai Takuma Higurashi Hiroshi Iida Kunihiro Hosono Hiroki Endo Takashi Nonaka Hirokazu Takahashi Tomoko Koide Yasunobu Abe Eiji Gotoh Shigeru Koyano Yoshiyuki Kuroiwa Shin Maeda Atsushi Nakajima | 2012 | World Journal of Gastroenterology2012，18，33： | 3 |

| 9 | Superconducting joints using reacted multifilament MgB_(2)wires:A technology toward cryogen-free MRI magnets显示文摘The development of superconducting joining technology for reacted magnesium diboride(MgB_(2))conductors remains a critical challenge for the advancement of cryogen-free MgB_(2)-based magnets for magnetic resonance imaging(MRI).Herein,the fabrication of superconducting joints using reacted carbon-doped multifilament MgB_(2)wires for MRI magnets is reported.To achieve successful superconducting joints,the powder-in-mold method was employed,which involved tuning the filament protection mechanism,the powder compaction pressure,and the heat treatment condition.The fabricated joints demonstrated clear superconducting-to-normal transitions in self-field,with effective magnetic field screening up to 0.5 T at 20 K.To evaluate the interface between one of the MgB_(2)filaments and the MgB_(2)bulk within the joint,serial sectioning was conducted for the first time in this type of superconducting joint.The serial sectioning revealed space formation at the interface,potentially caused by the volume shrinkage associated with the MgB_(2)formation or the combined effect of the volume shrinkage and the different thermal expansion coefficients of the MgB_(2)bulk,the filament,the mold,and the sealing material.These findings are expected to be pivotal in developing MgB_(2)superconducting joining technology for MRI magnet applications through interface engineering. | Dipak Patel Akiyoshi Matsumoto Hiroaki Kumakura Yuka Hara Toru Hara Minoru Maeda Hao Liang Yusuke Yamauchi Seyong Choi Jung Ho Kim Md Shahriar A.Hossain | 2024 | Journal of Magnesium and Alloys2024，12，1： | 0 |
| 10 | Effect of sumatriptan on gastric emptying:A crossover study using the BreathID system显示文摘AIM:To determine the effect of oral sumatriptan on gastric emptying using a continuous 13 C breath test(BreathID system).METHODS:Ten healthy male volunteers participated in this randomized,2-way crossover study.The subjects fasted overnight and were randomly assigned to receive a test meal(200 kcal/200 mL) 30 min after pre-medication with sumatriptan 50 mg(sumatriptan condition),or the test meal alone(control condition).Gastric emptying was monitored for 4 h after administration of the test meal by the 13 C-acetic acid breath test performed continually using the BreathID system.Then,using Oridion Research Software(β version),the time taken for emptying of 50% of the labeled meal(T 1/2) similar to the scintigraphy lag time for 10% emptying of the labeled meal(T lag),the gastric emptying coefficient(GEC),and the regression-estimated constants(β and κ) were calculated.The statistical significance of any differences in the parameters were analyzed using Wilcoxon's signed-rank test.RESULTS:In the sumatriptan condition,significant differences compared with the control condition were found in T 1/2 [median 131.84 min(range,103.13-168.70) vs 120.27 min(89.61-138.25);P = 0.0016],T lag [median 80.085 min(59.23-125.89) vs 61.11 min(39.86-87.05);P = 0.0125],and β [median 2.3374(1.6407-3.8209) vs 2.0847(1.4755-2.9269);P = 0.0284].There were no significant differences in the GEC or κ between the 2 conditions.CONCLUSION:This study showed that oral sumatriptan significantly delayed gastric emptying of a liquid meal. | Yasunari Sakamoto Yusuke Sekino Eiji Yamada Takuma Higurashi Hidenori Ohkubo Eiji Sakai Hiroki Endo Hiroshi Iida Takashi Nonaka Koji Fujita Masato Yoneda Tomoko Koide Hirokazu Takahashi Ayumu Goto Yasunobu Abe Eiji Gotoh Shin Maeda Atsushi Nakajima Masahiko Inamori | 2012 | World Journal of Gastroenterology2012，18，26： | 0 |
| 11 | Endoscopic diagnosis of Barrett's esophagus显示文摘The Prague C and M Criteria have been developed for the objective endoscopic diagnosis of Barrett's esophagus(BE).BE arises between the squamocolumnar junction and the gastroesophageal junction at the proximal margin of the gastric folds.In this study,we reported that 43.0% of the subjects examined were diagnosed with BE based on the Prague C and M Criteria.Previous criticism by John Dent proposed that our data should be considered invalid because the prevalence of BE reported in our study was extraordinarily high and discordant with previous studies.Dent predicted that the position of the gastroesophageal junction in our study was judged to be lower than the actual position due to the effacement of the proximal ends of the gastric folds because of the routine use of a high degree of air distension during typical Japanese endoscopic examinations.The endoscopic evaluation of the superior gastric folds is certainly influenced by the degree of air distension of the esophagus.However,in our study,the proximal limit of the gastric mucosal folds was prospectively imaged while the oesophagus was minimally insufflated.Then,under a high level of air distension,the distal ends of the palisade-shaped longitudinal vessels were imaged because they are more easily observed when distended.In the majority of patients,the distal ends of the palisade-shaped longitudinal vessels correspond to the proximal limit of the gastric mucosal folds.Our endoscopic evaluation was appropriately performed according to the Prague C and M Criteria.We suspect that the high prevalence of BE in our study may be due to the inclusion of ultrashort-segment BE,which defines BE with an affected mucosal length under 5 mm,in our positive results. | Tomoyuki Akiyama Yusuke Sekino Hiroshi Iida Shigeru Koyama Eiji Gotoh Shin Maeda Atsushi Nakajima Masahiko Inamori | 2012 | World Journal of Gastroenterology2012，18，26： | 0 |
