An 80-year-old woman was admitted to the hospital complaining of loss of appetite. 10 days earlier, her oral intake gradually decreased with no other specific symptoms, such as abdominal pain, nausea, vomiting, headache, or low back pain. Abdominal computed tomography (CT) scan revealed a left subcapsular renal hematoma. We suspected infective subcapsular renal hematoma, so percutaneous needle aspiration and drainage were performed. Intravenous sulbactam-ampicillin was started immediately. Ondoi:10.1007/s13730-018-0305-6 pmid:29344911 pmcid:PMC5886936 fatcat:bidsuxdt4nbgxg7lfevomycxg4

Follow-up CT scan on day 21 revealed increased subcapsular renal hematoma size. The patient also had high fever. Suspecting recurrence of infective subcapsular renal hematoma, we repeated the drainage of the hematoma and restarted intravenous antibiotics. Renal arteriography showed a renal artery microaneurysm and her condition improved with renal artery embolization. Renal arteriography was useful for detecting renal artery microaneurysm in infective subcapsular renal hematoma that did not resolve after antibiotic treatment and drainage.

Clostridium perfringens enterotoxin (CPE), a causative agent of food poisoning, is a pore-forming toxin disrupting the selective permeability of the plasma membrane of target cells, resulting in cell death. We previously identified claudin as the cell surface receptor for CPE. Claudin, a component of tight junctions, is a tetra-transmembrane protein and constitutes a large family of more than 20 members, not all of which serve as the receptor for CPE. The mechanism by which the toxindoi:10.1074/jbc.m109.051417 pmid:19903817 pmcid:PMC2804187 fatcat:kqjsyp72pzewleljdwlosepkbq

In this study, we localized the region of claudin responsible for interaction with CPE to the C-terminal part of the second extracellular loop, and found that the isoelectric point of this region in sensitive claudins was higher than insensitive claudins. Amino-acid substitutions to lower the pI resulted in reduced sensitivity to CPE among sensitive claudins, whereas substitutions to raise the pI endowed CPE-insensitive claudins with sensitivity. The steric structure of the claudin-binding domain of CPE reveals an acidic cleft surrounded by Tyr306, Tyr310, Tyr312, and Leu315, which were reported to be essential for interaction with the sensitive claudins. These results imply that an electrostatic attraction between the basic claudin region and the acidic CPE cleft is involved in their interaction. http://www.jbc.org/cgi/
Bovine Spongiform Encephalopathy (BSE) was first reported from the United Kingdom (UK) in 1986. Approximately 190,000 BSE cases were reported in the world, about 185,000 cases were detected in UK so far. BSE were transferred among cattle by Meat and Bone Meal with an inadequate heat treatment produced from Specified Risk Materials (SRM) of BSE cattle. Infectious agent is a proteinaceous infectious particles (prion), these are causative agents of BSE and also of variant Creutzfeldt-Jakob Diseasedoi:10.2743/jve.22.15 fatcat:g55ogsqyezg6joesz45tjujsoa

Atypical BSE has a different western blot pattern from typical BSE. There are two patterns, High and Low types. Atypical BSE case was borne sporadically, and onset of BSE symptoms were detected older than typical BSE case. Two L type cases were detected in Japan in 16,100,000 cattle tested so far. To prevent dissemination of BSE in the world, feed ban which is not fed SRM to cattle was introduced. 65 BSE cases were borne after real feed ban in the world. No typical BSE case was reported in 2017, therefore, typical BSE case will be eradicated near future in the world. 【牛海綿状脳症とは】 牛海綿状脳症(以下 BSE : Bovine Spongiform Encephalopathy)の最新事情を述べる前に BSE について振り返っ ておきたい 1) 。 BSE は英国で 1986 年に初めて報告された。BSE は異常 プリオンタンパク質と呼ばれる病原体が主に脳に蓄積する ことによって,神経細胞が壊死し,空胞変性を起こし,脳 の組織がスポンジ状になる。その結果,異常行動,運動失 調等の中枢神経症状を呈し,死に至ると考えられている。 プリオンとは感染性を有するタンパク質様の病原体を意 味する造語(proteinaceous infectious particles)で,牛海綿 状脳症(BSE)やヒトのクロイツフェルト・ヤコブ病(CJD) の原因物質とされている。 ヒトや動物の体内にはもともと正常プリオンタンパク質 が存在し,病原体である異常プリオンタンパク質が体内に 侵入すると,正常プリオンタンパク質が異常プリオンタン パク質に変性する。両者のアミノ酸配列は同じであるが, 立体構造が正常プリオンタンパク質ではαへリックス構造 であるのに対し,異常プリオンタンパク質ではβシート構 造になっていることが知られている。 牛から牛に BSE がまん延したのは,BSE 感染牛を原料 とした肉骨粉を牛の飼料として使っていたことが原因と考 えられている。英国で異常プリオンタンパク質に高度に汚 染された肉骨粉により多数の BSE 感染牛が確認されてい た時期における平均潜伏期間は,5 年から 5.5 年と推測さ れている。 国際獣疫事務局(OIE)の報告によれば,世界 28 か国 で約 19 万頭(2018 年 1 月時点)の BSE が発生し,英国 連絡先:山本茂貴* 内閣府食品安全委員会 〒107⊖6122 東京都港区赤坂 5⊖2⊖20 赤坂パークビル 22 階 Tel : 03⊖6234⊖1061
The Littlest Higgs with T-parity Model (LHT) is one of the attractive candidates of physics beyond the Standard Model. In this study we focus on heavy gauge bosons and heavy leptons that LHT imposes, which are detectable at ILC. The mass and couplings of these particles possess important information of the model's mass generation mechanism and how they interact with other particles. Precision measurement will be essential among verifying the model. We will address the measurement accuracy ofarXiv:1203.0762v1 fatcat:e3vagwdkbnfq7jylvje6jxireq

Degradation of Imazosulfuron, 1-(2-chloroimidazo [1,2-a] pyridin-3-ylsulfonyl)-3-(4,6dimethoxypyrimidin-2-yl)urea, in the flooded soils was studied under laboratory conditions using the compounds labeled with 14C at imidazopyridine and pyrimidine rings. Imazosulfuron showed significant difference in degradation rates between aerobic and anaerobic conditions, and disappeared from the soils with half-lives of approximately 60 and 3 days, respectively. Imazosulfuron was subjected to the cleavagedoi:10.1584/jpestics.21.171 fatcat:n4avv2as65dfrih3chifte7nfe

In the sterilized soils under aerobic and anaerobic conditions 30 days after the treatment, the degradation rate of imazosulfuron and amounts of degradation products except for HMS were similar to those observed in nonsterilized soils under aerobic conditions 30 days after the treatment. Imazosulfuron in the soils under aerobic conditions gradually disappeared with time by the hydrolysis of the sulfonylurea bond to give ADPM and IPSN, and finally mineralized to carbon dioxide. On the other hand, Imazosulfuron under anaerobic conditions was degraded by soil microorganisms, followed by conversion to soil organic matters.
Lanthanide complexes exhibit interesting spectroscopic properties yielding many applications as imaging probes, natural chirality amplifiers, and therapeutic agents. However, many properties are not fully understood yet. Therefore, we applied magnetic circular dichroism (MCD) spectroscopy, which provides enhanced information about the underlying electronic structure to a series of lanthanide compounds. The metals in the M 3+ state included Y, La, Eu, Tb, Dy, Ho, Er, Tm, Yb, and Lu; the spectradoi:10.1002/chir.22365 pmid:25116761 fatcat:duhp3kwvtje7lpxs6ezqdktu3i

While the MCD and UV-VIS absorption spectra were dominated by the porphyrin signal, metal binding significantly modulated them. MCD spectroscopy was found to be better suited to discriminate between various species than absorption spectroscopy alone. The main features and trends in the lanthanide series observed in MCD and absorption spectra of the complexes could be interpreted at the Density Functional Theory (DFT) level, with effective core potentials on metal nuclei. The sum over state (SOS) method was used for simulation of the MCD intensities. The combination of the spectroscopy and quantum-chemical computations is important for understanding the interactions of the metals with the organic compounds.

Vibrational spectroscopies proved extremely useful to study a broad range of molecules, including their structures and interactions. Additional structural sensitivity is provided by polarized techniques measuring different absorption or scattering of left-and right circularly polarized light. The vibrational optical activity (VOA) methods include Raman optical activity (ROA) and vibrational circular dichroism (VCD). Interpretation of the spectra, however, is largely dependent on time-consumingdoi:10.1007/978-981-10-5651-2_8 fatcat:sh5qlyv57nfp7onzyhfb3fpxiq

To be able to handle at a reasonable precision large molecules, such as biologically relevant systems, we developed a simplified method of transfer of vibrational atomic properties from smaller fragments to the system of interest. The method found many successful applications in the past, including spectra of proteins and nucleic acids, and appears useful also in connection with the multi-level computational techniques in the foreseeable future. In this chapter, we discuss the theoretical whereabouts of the transfer method and its related computational algorithms and describe typical applications to large molecules.
