1Molecular mechanisms regulating NLRP3 inflammasome activation显示文摘Inflammasomes 是表明触发煽动性的 caspases 的激活和 interleukin-1β 的成熟的建筑群的多蛋白质;。在各种各样的 inflammasome 建筑群之中, NLRP3 inflammasome 最好被描绘并且与各种各样的人的 autoinflammatory 和自体免疫的疾病被连接了。因此, NLRP3 inflammasome 可以是为反煽动性的治疗的一个有希望的目标。在这评论,我们总结 NLRP3 inflammasome 被在 cytosol 激活的机制的当前的理解。我们也描述激活或禁止 inflammasome 汇编的 NLRP3 inflammasome 建筑群的有约束力的搭挡。我们调整 NLRP3 inflammasome 发信号的机制的知识并且这些怎么影响煽动性的回答,提供进一步的卓见进潜在的治疗学的策略治疗与 NLRP3 inflammasome 的 dysregulation 联系的煽动性的疾病。Eun-Kyeong Jo Jin Kyung Kim Dong-Min Shin Chihiro Sasakawa 2016Cellular & Molecular Immunology2016,13,2:202
2An update on the regulatory mechanisms of NLRP3 inflammasome activation显示文摘The NOD-,LRR-,and pyrin domain-containing protein 3(NLRP3)inflammasome is a multiprotein complex involved in the release of mature interleukin-1βand triggering of pyroptosis,which is of paramount importance in a variety of physiological and pathological conditions.Over the past decade,considerable advances have been made in elucidating the molecular mechanisms underlying the priming/licensing(Signal 1)and assembly(Signal 2)involved in NLRP3 inflammasome activation.Recently,a number of studies have indicated that the priming/licensing step is regulated by complicated mechanisms at both the transcriptional and posttranslational levels.In this review,we discuss the current understanding of the mechanistic details of NLRP3 inflammasome activation with a particular emphasis on protein-protein interactions,posttranslational modifications,and spatiotemporal regulation of the NLRP3 inflammasome machinery.We also present a detailed summary of multiple positive and/or negative regulatory pathways providing upstream signals that culminate in NLRP3 inflammasome complex assembly.A better understanding of the molecular mechanisms underlying NLRP3 inflammasome activation will provide opportunities for the development of methods for the prevention and treatment of NLRP3 inflammasome-related diseases.Seungwha Paik Jin Kyung Kim Prashanta Silwal Chihiro Sasakawa Eun-Kyeong Jo 2021Cellular & Molecular Immunology2021,18,5:43
3High-density circulating fluidized bed gasifier for advanced IGCC/IGFC-Advantages and challenges显示文摘Coal-fired Integrated Gasification Combined Cycle(IGCC)and Integrated coal Gasification Fuel-cell Combined cycle(IGFC)are being developed as high-efficiency electric power generation technology.However,the highest theoretical gross thermal efficiency of the conventional IGCC/IGFC is still below 52%.In order to obtain higher power generation efficiency,an advanced IGCC(A-IGCC)or advanced IGFC(A-IGFC)system making use of the exergy recuperation concept by recycling waste heat from gas turbine or fuel cells for steam gasification of coal and biomass was proposed in our laboratory.Corresponding to this system,a novel high-density triple-bed combined circulating fluidized bed(TBCFB)gasifier,composed of a downer pyrolyzer,a bubbling fluidized bed char gasifier,and a riser combustor,was proposed to replace traditional gasifiers such as the entrained flow bed gasifier.The new system is expected to more effectively utilize the waste heat from gas turbines or fuel cells and the heat produced by the combustion of the unreacted char in the riser combustor for pyrolysis and gasification of coal and biomass.In this short review,the advantages and future challenges in the development of high-density TBCFB gasifier are presented and discussed.Guoqing Guan Chihiro Fushimi Atsushi Tsutsumi Masanori Ishizuka Satoru Matsuda Hiroyuki Hatano Yoshizo Suzuki 2010Particuology2010,8,6:17
4Bleeding after endoscopic submucosal dissection: Risk factors and preventive methods显示文摘Endoscopic submucosal dissection(ESD) has become widely accepted as a standard method of treatment for superficial gastrointestinal neoplasms because it enables en block resection even for large lesions or fibrotic lesions with minimal invasiveness, and decreases the local recurrence rate. Moreover, specimens resected in an en block fashion enable accurate histological assessment. Taking these factors into consideration, ESD seems to be more advantageous than conventional endoscopic mucosal resection(EMR), but the associated risks of perioperative adverse events are higher than in EMR. Bleeding after ESD is the most frequent among these adverse events. Although post-ESD bleeding can be controlled by endoscopic hemostasis in most cases, it may lead to serious conditions including hemorrhagic shock. Even with preventive methods including administration of acid secretion inhibitors and preventive hemostasis, post-ESD bleeding cannot be completely prevented. In addition high-risk cases for post-ESD bleeding, which include cases with the use of antithrombotic agents or which require large resection, are increasing. Although there have been many reports about associated risk factors and methods of preventing post-ESD bleeding, many issues remain unsolved. Therefore, in this review, we have overviewed risk factors and methods of preventing post-ESD bleeding from previous studies. Endoscopists should have sufficient knowledge of these risk factors and preventive methods when performing ESD.Yosuke Kataoka Yosuke Tsuji Yoshiki Sakaguchi Chihiro Minatsuki Itsuko Asada-Hirayama Keiko Niimi Satoshi Ono Shinya Kodashima Nobutake Yamamichi Mitsuhiro Fujishiro Kazuhiko Koike 2016World Journal of Gastroenterology2016,22,26:16
5Matrine promotes neural circuit remodeling to regulate motor function in a mouse model of chronic spinal cord injury显示文摘In chronic phase of spinal cord injury, functional recovery is more untreatable compared with early intervention in acute phase of spinal cord injury. In the last decade, several combination therapies successfully improved motor dysfunction in chronic spinal cord injury. However, their effectiveness is not sufficient. We previously found a new effective compound for spinal cord injury, matrine, which induced axonal growth and functional recovery in acute spinal cord injury mice via direct activation of extracellular heat shock protein 90. Although our previous study clarified that matrine was an activator of extracellular heat shock protein 90, the potential of matrine for spinal cord injury in chronic phase has not been sufficiently evaluated. Thus, this study aimed to investigate whether matrine ameliorates chronic spinal cord injury in mice. Once daily intragastric administration of matrine(100 μmol/kg per day) to spinal cord injury mice were starte at 28 days after injury, and continued for 154 days. Continuous mat rine treatment improved hindlimb motor function in chronic spinal cord injury mice. In injured spinal cords of the matrine-treated mice, the density of neurofilament-H-positive axons was increased. Moreover, matrine treatment increased the density of bassoon-positive presynapses in contact with choline acetyltransferase-positive motor neurons in the lumbar spinal cord. These findings suggest that matrine promotes remodeling and reconnection of neural circuits to regulate hindlimb movement.

17A case of small bowel adenocarcinoma in a patient with Crohn’s disease detected by PET/CT and double-balloon enteroscopy显示文摘Small bowel adenocarcinoma (SBA) in patients with Crohn’s disease (CD) is quite rare, difficult to diagnose without surgery, and has a poor prognosis. Here, we report a 48-year-old man with SBA and a 21-year history of CD who was diagnosed by a combination of positron emission tomography/computed tomography (PET/CT) and double-balloon enteroscopy (DBE). Since the age of 27 years, the patient had been treated for ileal CD and was referred to our hospital with persistent melena. Multiple hepatic tumors were found by CT. PET/CT detected an accumulation spot in the small bowel. DBE revealed an ulcerative tumor in the ileum about 100 cm from the ileocecal valve. An endoscopic forceps biopsy specimen showed poorly differentiated adenocarcinoma. There were some longitudinal ulcer scars near the tumor, and the chronic inflammation inthe small bowel appeared to be associated with the cancer development. Previous reports suggest the risk of SBA in patients with CD is higher than in the overall population. Since early diagnosis is extremely difficult in these cases, novel techniques, such as PET/CT and DBE, may be expected to help in making a preoperative diagnosis of the development of SBA in CD.Chise Kodaira Satoshi Osawa Chihiro Mochizuki Yoshihiko Sato Masafumi Nishino Takanori Yamada Yasuhiro Takayanagi Kosuke Takagaki Ken Sugimoto Shigeru Kanaoka Takahisa Furuta Mutsuhiro Ikuma 2009World Journal of Gastroenterology2009,15,14:2
18Sessile serrated adenoma detection rate is correlated with adenoma detection rate显示文摘AIM To investigated the association between adenoma detection rate(ADR) and sessile serrated ADR(SSADR) and significant predictors for sessile serrated adenomas(SSA) detection.METHODS This study is a retrospective, single-center analysis. Total colonoscopies performed by the gastroenterologists at the University of Tokyo Hospital between January and December 2014 were retrospectively identified. Polyps were classified as low-grade or high-grade adenoma, cancer, SSA, or SSA with cytological dysplasia, and the prevalence of each type of polyp was investigated. Predictors of adenoma and SSA detection were examined using logistic generalized estimating equation models. The association between ADR and SSADR for each gastroenterologist was investigated by calculating a correlation coefficient weighted by the number of each gastroenterologist's examination.RESULTS A total of 3691 colonoscopies performed by 35 gastroenterologists were assessed. Overall, 978 (26.5%) low-and 84 (2.2%) high-grade adenomas, 81 (2.2%) cancers, 66 (1.8%) SSAs, and 2 (0.1%) SSAs with cytological dysplasia were detected. Overall ADR was 29.5%(men 33.2%, women 23.8%) and overall SSADR was 1.8%(men 1.7%, women 2.1%). In addition, 672 low-grade adenomas (68.8% of all the detected lowgrade adenomas), 58 (69.9%) high-grade adenomas, 29 (34.5%) cancers, 52 (78.8%) SSAs, and 2 (100%) SSAs with cytological dysplasia were found in the proximal colon. Adenoma detection was the only significant predictor of SSA detection (adjusted OR: 2.53, 95%CI: 1.53-4.20; P < 0.001). The correlation coefficient between ADR and SSADR weighted by the number of each gastroenterologist's examinations was 0.606(P < 0.001).CONCLUSION Our results demonstrated that ADR is correlated to SSADR. In addition, patients with adenomas had a higher prevalence of SSAs than those without adenomas.Daisuke Ohki Yosuke Tsuji Tomohiro Shinozaki Yoshiki Sakaguchi Chihiro Minatsuki Hiroto Kinoshita Keiko Niimi Satoshi Ono Yoku Hayakawa Shuntaro Yoshida Atsuo Yamada Shinya Kodashima Nobutake Yamamichi Yoshihiro Hirata Tetsuo Ushiku Mitsuhiro Fujishiro Masashi Fukayama Kazuhiko Koike 2018World Journal of Gastrointestinal Oncology2018,10,3:2
