Objectives Transabdominal ultrasonography (US) has been reported as a useful tool for evaluating Crohn's disease (CD) activity. Endoscopic findings and activity index (CDAI) are currently considered the gold standard assessing CD We assessed correlation between US double-balloon endoscopy (DBE), CDAI Methods analyzed patients with undergoing DBE within 10 days procedures. The intestine was divi...

Henry's Law constants (HLCs) of several common, subsurface hydrophobic organic pollutants (HOPs) including trichloroethylene (TCE), perchloroethylene (PCE) and benzene, toluene, ethylbenzene, and o-xylene (BTEX), were measured using a static headspace phase ratio (SHPR) method over a range of temperatures (35, 45, 55, and 65 degrees C) and experimentally and operationally relevant cyclodextrin ...

Spatial concentrations and chemical fractions of heavy metals (Cr, Cu, Pb, Zn and Cd) in 16 sampling sites from the Honghu Lake were investigated using an atomic absorption spectrophotometer and optimized BCR (the European Community Bureau of Reference) three-stage extraction procedure. Compared with the corresponding probable effect levels (PELs), adverse biological effects of the studied five...

Land use of sewage sludge is the primary disposal method in Shanxi, accounting for 42.66% of all. To determine the ecological risk of heavy metals in sewage sludge, contents of seven heavy metals in sewage sludge from 9 municipal waste water treatment plants (WWTPs) that had the highest application for land use were determined. The order of the measured concentrations was: Zn > Cr > Cu > Ni > P...

Cd is one of the most common pollutants in the environment that also induces the apoptosis. To explore the mechanism of apoptosis in the hepatopancreas, freshwater crab S. henanense were treated with 0, 3.56, 7.12, 14.25, 28.49 and 56.98 mg/L Cd for 72 h. Apoptosis was noticeable in every treatment group and necrosis was observed clearly in the high concentration Cd groups. Classical apoptotic ...

A comprehensive analysis of the spatial and temporal variations heavy metals in wetland sediment can delineate changes possible contamination sources, providing valuable conservation strategies for further management. Using pollution index, enrichment factors, potential ecological risk (Cd, Hg, As, Pb, Cr, Cu, Zn) were evaluated Hengshui Lake north China 2005 2020. The results demonstrated that...

BACKGROUND/AIMS C-reactive protein (CRP) is a serologic activity marker in Crohn's disease (CD), but it may be less useful in evaluating CD activity in ileal CD patients. We aimed to investigate the usefulness of CRP as a disease activity marker in CD according to disease location. METHODS Korean CD patients in a single hospital were evaluated. Factors associated with elevated CRP concentrati...

Intestinal inflammation and mucosal damage in Crohn's disease (CD) are believed to progress even during clinical remission. We investigated the long-term prognosis of CD patients in clinical remission according to serum C-reactive protein (CRP) levels. This study included 339 CD patients in clinical remission (Crohn's disease activity index < 150) for more than 6 months between January 2008 and...

1.はじめに CGで現実感のある画像を生成する技術は、いかにして物体を 忠実に表現するかの技術である。物体を特徴付ける要素として は、大きく分けて、物体の形状と、物体表面の色情報や光学属 性などの表面属性がある。物体の表面属性を表現する場合、一 般的には、バンプマッピングなどのさまざまなマッピング手法 がとられている。CGデザイナがマッピングに利用できる素材と しては、市販の CD-ROM やインターネット経由で入手できる素 材集、およびテクスチャ生成のプログラムから出力されるデー タなどがある。 本報告で取り扱う石畳を表現する場合、CGデザイナが路面の 敷石を1つ1つモデリングして表現することが理想ではある が、大変な労力を要するため現実的ではない。一方、石畳の写 真素材を路面にマッピングして表現することも可能であるが、 以下のような問題が生ずる。 ・テクスチャ全体として凹凸が激し...

background: evaluation of heavy metals as toxic pollutants in environment has a significant importance in environmental pollution studies. surficial sediments of water resources have a high potential in releasing heavy metals to the upper water environment, hence sediment analysis presents guidelines to the authorities for monitoring the environmental systems. methods: in this study, total and ...
