1Does a combined intervention program of repetitive transcranial magnetic stimulation and intensive occupational therapy affect cognitive function in patients with post-stroke upper limb hemiparesis?显示文摘Low-frequency repetitive transcranial magnetic stimulation(LF-r TMS) to the contralesional hemisphere and intensive occupational therapy(i OT) have been shown to contribute to a significant improvement in upper limb hemiparesis in patients with chronic stroke. However, the effect of the combined intervention program of LF-r TMS and i OT on cognitive function is unknown. We retrospectively investigated whether the combined treatment influence patient's Trail-Making Test part B(TMT-B) performance, which is a group of easy and inexpensive neuropsychological tests that evaluate several cognitive functions. Twenty-five patients received 11 sessions of LF-r TMS to the contralesional hemisphere and 2 sessions of i OT per day over 15 successive days. Patients with right- and left-sided hemiparesis demonstrated significant improvements in upper limb motor function following the combined intervention program. Only patients with right-sided hemiparesis exhibited improved TMT-B performance following the combined intervention program, and there was a significant negative correlation between Fugl-Meyer Assessment scale total score change and TMT-B performance. The results indicate the possibility that LF-r TMS to the contralesional hemisphere combined with i OT improves the upper limb motor function and cognitive function of patients with right-sided hemiparesis. However, further studies are necessary to elucidate the mechanism of improved cognitive function.Takatoshi Hara Masahiro Abo Kiyohito Kakita Takeshi Masuda Ryunosuke Yamazaki 2016Neural Regeneration Research2016,11,12:18
2Laparoscopy in the management of hilar cholangiocarcinoma显示文摘The use of minimally invasive surgery has become widely accepted in many gastrointestinal fields,even in patients with malignancy.However,performing laparoscopic resection for the treatment of hilar cholangiocarcinoma is still not universally accepted as an alternative approach to open surgery,and only a limited number of such procedures have been reporteddue to the difficulty of performing oncologic resection and the lack of consensus regarding the adequacy of this approach.Laparoscopy was initially limited to staging,biopsy and palliation.Recent technological developments and improvements in endoscopic procedures have greatly expanded the applications of laparoscopic liver resection and lymphadenectomy,and some reports have described the use of laparoscopic or robot-assisted laparoscopic resection for hilar cholangiocarcinoma as being feasible and safe in highly selected cases,with the ability to obtain an adequate surgical margin.However,the benefits of major laparoscopic surgery have yet to be conclusively proven,and carefully selecting patients is essential for successfully performing this procedure.Akihiro Cho Hiroshi Yamamoto Osamu Kainuma Yorihiko Muto Hiroo Yanagibashi Toru Tonooka Takahito Masuda 2014World Journal of Gastroenterology2014,20,41:18
3Small-for-size syndrome in liver transplantation:Definition,pathophysiology and management显示文摘Background:Since the first success in an adult patient,living donor liver transplantation(LDLT)has become an universally used procedure.Small-for-size syndrome(SFSS)is a well-known complication after partial LT,especially in cases of adult-to-adult LDLT.The definition of SFSS slightly varies among transplant physicians.The use of a partial liver graft has risks of SFSS development.Persistent portal vein(PV)hypertension and PV hyper-perfusion after LT were identified as the main factors.Hence,various approaches were explored to modulate PV flow and decrease PV pressure in order to alleviate this syndrome.Herein,the definition,clinical symptoms,pathophysiology,basic research,as well as preventive and treatment strategies for SFSS are reviewed based on an extensive review of the literature and on our own experiences.Data sources:The articles were collected through PubMed using search terms“liver transplantation”,“living donor liver transplantation”,“living liver donation”,“partial graft”,“small-for-size graft”,“small-forsize syndrome”,“graft volume”,“remnant liver”,“standard liver volume”,“graft to recipient body weight ratio”,“sarcopenia”,“porcine”,“swine”,and“rat”.English publications published before March 31,2020 were included in this review.Results:Many transplant surgeons performed PV flow modulation,including portocaval shunt,splenic artery ligation and splenectomy.With these techniques,patient outcome has been improved even when using a'small'graft.Other factors,such as preoperative recipients’nutritional and skeletal muscle status,graft congestion,and donor factors,were also identified as risk factors which all have been addressed using various strategies.Conclusions:The surgical approach controlling PV flow and pressure could help to prevent SFSS especially in severely ill recipients.In the absence of efficacious medications to resolve SFSS,conservative treatments,including aggressive fluid balance correction for massive ascites,anti-microbiological therapy to prevent or control sepsis and intensive nutritional therapy,are all required if SFSS could not be prevented.Yuichi Masuda Kazuki Yoshizawa Yasunari Ohno Atsuyoshi Mita Akira Shimizu Yuji Soejima 2020Hepatobiliary & Pancreatic Diseases International2020,19,4:13
4Condyloma acuminatum of the anal canal,treated with endoscopic submucosal dissection显示文摘Condyloma acuminatum(CA) is a common sexually transmitted disease caused by human papilloma virus infection. Not all individuals develop persistent, progressive disease, but careful follow up is required with moderate-to-severe dysplasia to prevent progression to malignancy. Standard therapies include surgical treatments(trans-anal resection and transanal endoscopic microsurgery) and immunotherapeutic and topical methods(topical imiquimod); however, local recurrence remains a considerable problem. Here, we report a case with superficial CA of the anal canal, treated with endoscopic submucosal dissection(ESD). A 28-year-old man presented with a chief complaint of hematochezia. Digital exam did not detect a tumor. Screening colonoscopy revealed 10-mm long, whitish condyles extending from the anal canal to the lower rectum. The lesion covered almost the whole circumference, and only a small amount of normal mucosa remained. Magnifying endoscopy with narrow band imaging showed brownish hairpin-shaped, coiled capillaries. Although histopathological diagnosis by biopsy revealed CA, accurate histological differentiation between CA, papilloma, and squamous cell carcinoma can be difficult with a small specimen. Therefore, weperformed diagnostic ESD, which provides a complete specimen for precise histopathological evaluation. The pathological diagnosis was CA, with moderate dysplasia(anal intraepithelial neoplasia 2). There was no recurrence at 16 mo after the initial ESD. Compared to surgical treatment, endoscopic diagnosis and resection could be performed simultaneously and the tumor margin observed clearly with a magnifying chromocolonoscopy, resulting in less recurrence. These findings suggest that endoscopic resection may be an alternative method for CA that prevents recurrence.Akiko Sasaki Takeshi Nakajima Hideto Egashira Kotaro Takeda Shinnosuke Tokoro Chikamasa Ichita Sakue Masuda Haruki Uojima Kazuya Koizumi Takeshi Kinbara Taku Sakamoto Yutaka Saito Makoto Kako 2016World Journal of Gastroenterology2016,22,8:11
5Biomarkers for individualized dosage adjustments in immunosuppressive therapy using calcineurin inhibitors after organ transplantation显示文摘Calcineurin inhibitors (CNIs), such as cyclosporine A and tacrolimus, are widely used immunosuppressive agents for the prevention of post-transplantation rejection and have improved 1-year graft survival rates by up to 90%. However, CNIs can induce severe reactions, such as acute or chronic allograft nephropathy, hypertension, and neurotoxicity. Because CNIs have varied bioavailabilities, narrow therapeutic ranges, and individual propensities for toxic effects, therapeutic drug monitoring is necessary for all CNIs. Identifying the genetic polymorphisms in drug-metabolizing enzymes will help to determine personalized dosage regimens for CNIs, as CNIs are substrates for CYP3A5 and P-glycoprotein (P-gp, MDR1). CNIs are often concomitantly administered with voriconazole or proton pump inhibitors (PPIs), giving rise to drug interaction problems. Voriconazole and PPIs can increase the blood concentrations of CNIs, and both are primarily metabolized by CYP2C19. Thus, it is expected that interactions between CNIs and voriconazole or PPI would be affected by CYP2C19 and CYP3A5 polymorphisms. CNI-induced acute kidney injury (AKI) is a serious complication of transplantations. Neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule 1 (KIM-1) are noninvasive urinary biomarkers that are believed to be highly sensitive to CNI-induced AKI. In this article, we review the adverse events and pharmacokinetics of CNIs and the biomarkers related to CNIs, including CYP3A5, CYP2C19, MDR1, NGAL, and KIM-1. We hope that these data will help to identify the optimal biomarkers for monitoring CNI-based immunosuppressive therapy after organ transplantation.Rao Fu Soichiro Tajima Kimitaka Suetsugu Hiroyuki Watanabe Nobuaki Egashira Satohiro Masuda 2019Acta Pharmacologica Sinica2019,40,2:10
6新辅助化疗后行腹腔镜辅助胃切除术治疗晚期胃癌显示文摘目前治疗晚期胃癌的方法为开腹胃切除及D2淋巴结清扫并在术后行S-1或卡倍他滨加奥沙利铂辅助化疗。然而III期胃癌患者的预后并不理想。为了提高生存率,需要加大化疗药物的剂量。鉴于患者接受二联或三联化疗的顺应性差,新辅助化疗将是一个充满前景的方法。目前在东亚国家,正进行多项III期临床试验用于评估新辅助化疗效果。另一方面,手术治疗方法已倾向于行腹腔镜手术。在日本和韩国已经进行了多项III期临床试验评估腹腔镜辅助远端胃切除(LADG)在早期和晚期患者中的疗效。因此,未来标准治疗肿瘤位于中、下1/3晚期胃癌的候选方案由综合治疗组成,包括新辅助化疗及随后的LADG。只要新辅助化疗是按标准实施,随后的腹腔镜胃切除术的可行性、安全性及长期生存率是有保障的。在这个背景下,我们实施了一项随机II期临床试验比较新辅助化疗后LADG和开腹远端胃切除术(ODG)治疗胃癌的疗效。Takaki Yoshikawa Takashi Oshima Yasushi Rino Munetaka Masuda 2013中国普通外科杂志2013,22,10:9
7Clinical outcomes of ampullary neoplasms in resected margin positive or uncertain cases after endoscopic papillectomy显示文摘BACKGROUND Endoscopic papillectomy(EP) for benign ampullary neoplasms could be a lessinvasive alternative to pancreatoduodenectomy(PD). There are some problems and limitations with EP. The post-EP resection margins of ampullary tumors are often positive or uncertain because of the burning effect of EP. The clinical outcomes of resected margin positive or uncertain cases after EP remain unknown.AIM To investigate the clinical outcomes of resected margin positive or uncertain cases after EP.METHODS Between January 2007 and October 2018, all patients with ampullary tumors who underwent EP at Kobe University Hospital were included in this study. The indications for EP were as follows: adenoma, as determined by preoperative endoscopic biopsy, without bile/pancreatic duct extension, according to endoscopic ultrasound or intraductal ultrasound. The clinical outcomes of resected margin positive or uncertain cases after EP were retrospectively investigated.RESULTS Of the 45 patients, 29 were male, and 16 were female. The mean age of the patients was 65 years old. Forty-one patients(89.5%) underwent en bloc resection,and 4 patients(10.5%) underwent piecemeal resection. After EP, 33 tumors were histopathologically diagnosed as adenoma, and 12 were diagnosed as adenocarcinoma. The resected margins were positive or uncertain in 24 patients(53.3%). Of these cases, 15 and 9 were diagnosed as adenoma and adenocarcinoma, respectively. Follow-up observation was selected for all adenomas and 5 adenocarcinomas. In the remaining 4 adenocarcinoma cases,additional PD was performed. Additional PD was performed in 4 cases, and residual carcinoma was found after the additional PD in 1 of these cases. In the follow-up period, local tumor recurrence was detected in 3 cases. Two of these cases involved primary EP-diagnosed adenoma. The recurrent tumors were also adenomas detected by biopsy. The remaining case involved primary EPdiagnosed adenocarcinoma. The recurrent tumor was also an adenocarcinoma.All of the recurrent tumors were successfully treated with argon plasma coagulation(APC). There was no local or lymph node recurrence after the APC.The post-APC follow-up periods lasted for 57.1 to 133.8 mo. No ampullary tumor-related deaths occurred in all patients.CONCLUSION Resected margin positive or uncertain cases after EP could be managed by endoscopic treatment including APC, even in cases of adenocarcinoma. EP could become an effective less-invasive first-line treatment for early stage ampullary tumors.Arata Sakai Masahiro Tsujimae Atsuhiro Masuda Takao Iemoto Shigeto Ashina Kohei Yamakawa Takeshi Tanaka Shunta Tanaka Yasutaka Yamada Ryota Nakano Yu Sato Manabu Kurosawa Takuya Ikegawa Seiji Fujigaki Takashi Kobayashi Hideyuki Shiomi Yoshifumi Arisaka Tomoo Itoh Yuzo Kodama 2019World Journal of Gastroenterology2019,25,11:9
8Clinical significance of white gastric crypt openings observed via magnifying endoscopy显示文摘AIM:To evaluate the relationship between Helicobacter pylori(H.pylori)-induced gastritis and white gastric mucosal crypt openings(COs)in the gastric corpus.METHODS:A total of 175 consecutive patients(including 69 patients with gastric cancer)were enrolled in this study.We used magnifying endoscopy(ME)to observe the mucosa microsurface of the lesser and greater curvature of the gastric corpus(350 areas in all).We focused on areas with a round pit microstructure(primarily observed in non-atrophied areas)and evaluated the white openings of these gastric pits.We classified the whiteness of the COs as the'white-edged dark spot'type(consisting of a dark spot bordered by white);the'white'type(pure white with no dark spot);and the'dense white pit(DWP)'type(dense white,resembling a snowball).Gastritis was also histologically evaluated according to the updated Sydney System.RESULTS:We detected round COs using ME in 246 of the 350 areas examined.The histological examination showed significantly more mononuclear cells and neutrophil infiltration in the'white'and'DWP'types than the'white-edged dark spot'type(P<0.001).Furthermore,significantly high-grade inflammation and evidence of active H.pylori-induced gastritis was observed in the'DWP'type(P<0.001).Significant differences were observed in the whiteness of COs between H.pylori-positive(n=139)and negative(n=36)patients(P<0.001).The sensitivity and specificity of the'white'and'DWP'types for predicting H.pylori infection were78.5%and 81.7%,respectively.Of the patients with gastric cancer,22.5%(18/80)had'white-edged dark spots',51.3%(41/80)had'white'COs,and 26.3%(21/80)had'DWP'-type COs.'DWPs'were frequently observed among patients with undifferentiated gastric cancer[45.7%(16/35)].CONCLUSION:CO whiteness detected via ME was associated with histological evidence of gastritis and helps to predict the severity of inflammation and H.pyloriinduced activity.Masashi Kawamura Hitoshi Sekine Shu Abe Daisuke Shibuya Katsuaki Kato Takayuki Masuda 2013World Journal of Gastroenterology2013,19,48:7
9REE Tetrad Effects in Rare-metal Granites显示文摘Described in this paper are the characteristics of tetrad effects of REE in rare-metal granites.Based on the analytical data and experimental geochemical data available,it is pointed out that the tetrad effects of REE in the granites are produced in the metal-fluid system.Intense fractional crystallization of granitic melt(containing REE accessary minerals)and its interaction with volatile-rich(F,Cl)fluid are the major factors leading to the tetrad effects of REE.From this,this paper presents a composite genetic model for high-degree fractional crystallization-volatile-rich fluid metasomatism of rare-metal granites.With the model,quantitative calculations have been made.Meanwhile,it is pointed out that the tetrad effects of REE can be used as an important indicator to distinguish mineralized granites from barren ones.赵振华 AKIMASA MASUDA M.B.SHABANI 1993Chinese Journal Of Geochemistry1993,12,3:6
10Colon perforation due to antigenemia-negative cytomegalovirus gastroenteritis after liver transplantation: A case report and review of literature显示文摘BACKGROUND Cytomegalovirus(CMV) remains a critical complication after solid-organ transplantation. The CMV antigenemia(AG) test is useful for monitoring CMV infection. Although the AG-positivity rate in CMV gastroenteritis is known to be low at onset, almost all cases become positive during the disease course. We treated a patient with transverse colon perforation due to AG-negative CMV gastroenteritis, following a living donor liver transplantation(LDLT).CASE SUMMARY The patient was a 52-year-old woman with decompensated liver cirrhosis as a result of autoimmune hepatitis who underwent a blood-type compatible LDLT with her second son as the donor. On day 20 after surgery, upper and lower gastrointestinal endoscopy(GE) revealed multiple gastric ulcers and transverse colon ulcers. The biopsy tissue immunostaining confirmed a diagnosis of CMV gastroenteritis. On day 28 after surgery, an abdominal computed tomography revealed transverse colon perforation, and simple lavage and drainage were performed along with an urgent ileostomy. Although the repeated remission and aggravation of CMV gastroenteritis and acute cellular rejection made the control of immunosuppression difficult, the upper GE eventually revealed an improvement in the gastric ulcers, and the biopsy samples were negative for CMV. The CMV-AG test remained negative, therefore, we had to evaluate the status of the CMV infection on the basis of the clinical symptoms and GE.CONCLUSION This case report suggests a monitoring method that could be useful for AGnegative CMV gastroenteritis after a solid-organ transplantation.Takahiro Yokose Hideaki Obara Masahiro Shinoda Yutaka Nakano Minoru Kitago Hiroshi Yagi Yuta Abe Yohei Yamada Kentaro Matsubara Go Oshima Shutaro Hori Sho Ibuki Hisanobu Higashi Yuki Masuda Masanori Hayashi Miho Kawaida Takehiko Mori Takumi Fujimura Ken Hoshino Kaori Kameyama Tatsuo Kuroda Yuko Kitagawa 2019World Journal of Gastroenterology2019,25,15:5
11Factors associated with residual gastroesophageal reflux disease symptoms in patients receiving proton pump inhibitor maintenance therapy显示文摘AIM To elucidate the factors associated with residual gastroesophageal reflux disease(GERD) symptoms in patients receiving proton pump inhibitor(PPI) maintenance therapy in clinical practice.METHODS The study included 39 GERD patients receiving maintenance PPI therapy. Residual symptoms were assessed using the Frequency Scale for Symptoms of GERD(FSSG) questionnaire and the Gastrointestinal Symptom Rating Scale(GSRS). The relationships between the FSSG score and patient background factors, including the CYP2C19 genotype, were analyzed.RESULTS The FSSG scores ranged from 1 to 28 points(median score: 7.5 points), and 19 patients(48.7%) had a score of 8 points or more. The patients' GSRS scores were significantly correlated with their FSSG scores(correlation coefficient = 0.47, P < 0.005). In erosive esophagitis patients, the FSSG scores of the CYP2C19 rapid metabolizers(RMs) were significantly higher than the scores of the poor metabolizers and intermediate metabolizers(total scores: 16.7 ± 8.6 vs 7.8 ± 5.4, P < 0.05; acid reflux-related symptom scores: 12 ± 1.9 vs 2.5 ± 0.8, P < 0.005). In contrast, the FSSG scores of the CYP2C19 RMs in the non-erosive reflux disease patients were significantly lower than those of the other patients(total scores: 5.5 ± 1.0 vs 11.8 ± 6.3, P < 0.05; dysmotility symptom-related scores: 1.0 ± 0.4 vs 6.0 ± 0.8, P < 0.01). CONCLUSION Approximately half of the GERD patients receiving maintenance PPI therapy had residual symptoms associated with a lower quality of life, and the CYP2C19 genotype appeared to be associated with these residual symptoms.Fumiaki Kawara Tsuyoshi Fujita Yoshinori Morita Atsushi Uda Atsuhiro Masuda Masaya Saito Makoto Ooi Tsukasa Ishida Yasuyuki Kondo Shiei Yoshida Tatsuya Okuno Yoshihiko Yano Masaru Yoshida Hiromu Kutsumi Takanobu Hayakumo Kazuhiko Yamashita Takeshi Hirano Midori Hirai Takeshi Azuma 2017World Journal of Gastroenterology2017,23,11:5
12应力比对WC-Co硬质合金疲劳寿命及裂纹生长行为的影响(英文)显示文摘通过两种疲劳试验:旋转弯曲疲劳试验和3-或4-点弯曲疲劳试验测试细晶WC-Co硬质合金的裂纹生长行为和疲劳寿命。疲劳试验结果表明:所测试的大部分WC-Co硬质合金的疲劳寿命取决于裂纹生长周期。利用断裂力学基本方程推导出疲劳裂纹生长速率(da/dN)和最大应力强度因子(Kmax)的关系。根据此关系,获得材料的强度因子阈值(Kth)和疲劳断裂韧性值(Kfc)。基于修正的线性弹性断裂力学方程,对WC-Co硬质合金材料的疲劳寿命进行计算,疲劳寿命的计算结果与实验结果吻合较好。Hiroko MIKADO Sotomi ISHIHARA Noriyasu OGUMA Kenichi MASUDA Syo KITAGAWA Shingo KAWAMURA 2014Transactions of Nonferrous Metals Society of China2014,24,S1:4
13Liver cirrhosis induced by long-term administration of a daily low dose of amiodarone: A case report显示文摘The anti-arrhythmic agent amiodarone (AD) is associated with numerous adverse effects, but serious liver disease is rare. The improved safety of administration of daily low doses of AD has already been established and this regimen is used for long-term medication. Nevertheless,asymptomatic continuous liver injury by AD may increase the risk of step-wise progression of non-alcoholic fatty liver disease. We present an autopsy case of AD-induced liver cirrhosis in a patient who had been treated with a low dose of AD (200 mg/d) daily for 84 mo. The patient was a 85-year-old male with a history of ischemic heart disease.Seven years after initiation of treatment with AD, he was admitted with cardiac congestion. The total dose of AD was 528 g. Mild elevation of serum aminotransferase and hepatomegaly were present. Liver biopsy specimens revealed cirrhosis, and under electron microscopy numerous lysosomes with electron-dense, whorled, lamellar inclusions characteristic of a secondary phospholipidosis were observed. Initially, withdrawal of AD led to a slight improvement of serum aminotransferase levels, but unfortunately his general condition deteriorated and he died from complications of pneumonia and renal failure.Long-term administration of daily low doses of AD carries the risk of progression to irreversible liver injury. Therefore,periodic examination of liver function and/or liver biopsy is required for the management of patients receiving long-term treatment with AD.Hiroki Oikawa Chihaya Maesawa Ryo Sato Kanta Oikawa Hiroyuki Yamada Seizo Oriso Sadahide Ono Akiko Yashima-Abo Koji Kotani Kazuyuki Suzuki Tomoyuki Masuda 2005World Journal of Gastroenterology2005,11,34:4
14Dual therapy for third-line Helicobacter pylori eradication and urea breath test prediction显示文摘We evaluated the efficacy and tolerability of a dual therapy with rabeprazole and amoxicillin (AMX) as an empiric third-line rescue therapy. In patients with failure of first-line treatment with a proton pump inhibitor (PPI)- AMX-clarithromycin regimen and second-line treatment with the PPI-AMX-metronidazole regimen, a third-line eradication regimen with rabeprazole (10 mg q.i.d.) and AMX (500 mg q.i.d.) was prescribed for 2 wk. Eradication was confirmed by the results of the 13C-urea breath test (UBT) at 12 wk after the therapy. A total of 46 patients were included; however, two were lost to followup. The eradication rates as determined by per-protocol and intention-to-treat analyses were 65.9% and 63.0%,respectively. The pretreatment UBT results in the subjects showing eradication failure; those patients showing successful eradication comprised 32.9 ± 28.8 permil and 14.8 ± 12.8 permil, respectively. The pretreatment UBT results in the subjects with eradication failure were significantly higher than those in the patients with successful eradication (P = 0.019). A low pretreatment UBT result (≤ 28.5 permil) predicted the success of the eradication therapy with a positive predictive value of 81.3% and a sensitivity of 89.7%. Adverse effects were reported in 18.2% of the patients, mainly diarrhea and stomatitis. Dual therapy with rabeprazole and AMX appears to serve as a potential empirical third-line strategy for patients with low values on pretreatment UBT.Toshihiro Nishizawa Hidekazu Suzuki Takama Maekawa Naohiko Harada Tatsuya Toyokawa Toshio Kuwai Masanori Ohara Takahiro Suzuki Masahiro Kawanishi Kenji Noguchi Toshiyuki Yoshio Shinji Katsushima Hideo Tsuruta Eiji Masuda Munehiro Tanaka Shunsuke Katayama Norio Kawamura Yuko Nishizawa Toshifumi Hibi Masahiko Takahashi 2012World Journal of Gastroenterology2012,18,21:4
15发电不确定性条件下电动汽车对智能家居能量管理的贡献(英文)显示文摘光伏、风电等可再生能源的大规模接入给电力系统的运行带来了诸多问题,如由发电过剩引起的电网反向潮流、电网频率和节点电压调节容量的不足。作为解决可再生能源出力波动性引起的不确定性问题的方法之一,采用电动汽车作为储能装置,即所谓的V2H(vehicle to house)或者V2G(vehicle to grid),将发挥重要作用,因此有必要建立电动汽车应用评估方法。以配有光伏发电装置和一辆电动汽车的某智能家居为例,定量评估了电动汽车电池充放电对光伏发电输出功率的家庭内部使用比例、家庭用电成本和CO2排放量的影响。分析结果表明,通过光伏发电装置和电功汽车电池的有效配合使用,可以减少反向潮流和CO2排放。最后,通过仿真分析论证了多辆电动汽车对含有多栋智能家居的智能化小区能量管理的贡献。Ryuichi YOKOYAMA Kouichirou YOSHIMI Takahiko MASUDA Haruhiko KONDOU 2011电力系统自动化2011,35,22:4
16A case of mucosa-associated lymphoid tissue lymphoma of the gastrointestinal tract showing extensive plasma cell differentiation with prominent Russell bodies显示文摘A 73-year-old Japanese woman was hospitalized for detailed examination of nausea, diarrhea and loss of appetite. Atypical erosion in the ileum was found on endoscopy. Biopsy of this erosion showed proliferation of cells containing numerous Russell bodies. Differential diagnoses considered were Russell body enteritis, crystal-storing histiocytosis, Mott cell tumor, immunoproliferative small intestinal disease(IPSID) and mucosaassociated lymphoid tissue(MALT) lymphoma. The cells containing prominent Russell bodies showed diffuse positivity for CD79 a and CD138, but negative results for CD20, CD3, UCHL-1, CD38 and CD68. Russell bodies were diffusely positive for lambda light chain, but negative for kappa light chain, and immunoglobulin(Ig)G, Ig A and Ig M. Based on these findings, Russell body enteritis, crystal-storing histiocytosis and IPSID were ruled out. As the tumor formed no mass lesions and was restricted to the gastrointestinal tract, MALT lymphoma with extensive plasma cell differentiation was finally diagnosed. The patient showed an unexpectedly aggressive clinical course. The number of atypical lymphocytes in peripheral blood gradually increased and T-prolymphocytic leukemia(T-PLL) emerged. The patient died of T-PLL 7 mo after admission. Autopsy was not permitted.Keita Kai Masaharu Miyahara Yasunori Tokuda Shinich Kido Masanori Masuda Yukari Takase Osamu Tokunaga 2013World Journal of Clinical Cases2013,1,5:4
17Recycle for Sludge Scrap of Nd-Fe-B Sintered Magnet as Isotropic Bonded Magnet显示文摘The reduction diffusion method was performed for the sludge scrap of Nd-Fe-B sintered magnets with adding Ca metal to recover the oxidized Nd-Fe-B phase. After washing the resultant powders to remove Ca metal component, the powders obtained were recycled as an isotropic magnetic powder by the melt spinning method. The magnetic properties of powders as recycled were inferior, especially for the coercivity value, due to the deletion of rare earth metals during the washing process. The adjustment of metal composition, i.e., the addition of Nd metal, at the melt spinning process improved the magnetic properties to be B r=~0.75 T, H cj=~0.93 mA·m -1, and (BH) max=~91 kJ·m -3. The magnetic properties of the bonded magnets prepared from the composition-adjusted powders were B r=~0.66 T, H cj=~0.92 mA·m -1, and (BH) max=~70 kJ·m -3, which are approximately comparable to the commercially available MQPB boned one (B r=~0.73 T, H cj=~0.79 mA·m -1, and (BH) max=~86 kJ·m -3).Masahiro Itoh Masahiro Masuda Shunji Suzuki Ken-ichi Machida 2004Journal of Rare Earths2004,22,1:4
