A new polyvinyl choloride (PVC) membrane sensor for cerium (III) was prepared based on 4,13-didecyl-1,7,10,16-tetraoxa-4,13-diazacyclooctadecane (kryptofix22DD) as an ionophore. The sensor exhibites a linear concentration range of 1.0×10-6 to 1.0×10-1 M, with a Nernstian slope of 18.0±1.0 mV/decade, and a detection limit of 9.7×10-7 M. It has a fast response tim...

Lattice, Ce L3-edge, magnetic susceptibility, and electrical resistivity results on polycrystalline Sm1−xCexMn2Ge2 (0≤ x≤ 1) compound series are presented. The lattice parameters a and c increase almost linearly with the increase of Ce concentration x. The Ce-L3 X-ray absorption spectra indicate that the Ce in this series is nearly trivalent, and Ce valence decreases slightly with the increase ...

BACKGROUND Cystic echinococcosis (CE), as a chronic parasitic disease, is a major health problem in many countries. The performance of the currently available serodiagnostic tests for the diagnosis of CE is unsatisfactory. OBJECTIVE The current study aimed at sub-cloning a gene, encoding the B8/1 subunit of antigen B (AgB) from Echinococcus granulosus, using gene optimization for the immunodi...

Background: Cocaethylene (CE) is known to increase the permeability of human microvascular endothelial cell monolayers. The molecular mechanism underlying this increase may involve calcium-modulated signaling pathways such as the p38 mitogen-activated protein kinase (p38 MAPK) and the nuclear factorB (NFB) family of transcription factors. The hypothesis of this study was that CE-mediated endoth...

The aim of the present study was to measure lanthanum (La), cerium (Ce), europium (Eu), and gadolinium (Gd) concentrations in human semen and correlate the results with sperm quality. The median semen content of La was 19.5 µg kg(-1) dry weight (dw) (range 2.27-269), of Ce was 41.9 µg kg(-1) dw (range 4.52 to 167), of Eu was 0.68 µg kg(-1) dw (range 0.06-1.95), of Gd was 3.19 µg kg(-1) dw (rang...

PURPOSE To compare the added value of dynamic contrast material-enhanced ( CE contrast enhanced ) ( DCE dynamic CE ) magnetic resonance (MR) imaging with that of dynamic susceptibility CE contrast enhanced ( DSC dynamic susceptibility CE ) MR imaging with the combination of CE contrast enhanced T1-weighted imaging and diffusion-weighted ( DW diffusion weighted ) imaging for predicting recurrent...

BACKGROUND Cocaethylene (CE) is known to increase the permeability of human microvascular endothelial cell monolayers. The molecular mechanism underlying this increase may involve calcium-modulated signaling pathways such as the p38 mitogen-activated protein kinase (p38 MAPK) and the nuclear factor-kappaB (NF-kappaB) family of transcription factors. The hypothesis of this study was that CE-medi...

Sit-to-stand exercise (STS) is a common activity of daily living. The objectives of the present study were: 1) to assess the validity of aerobic fitness measurements based on anaerobic thresholds (ATs), during incremental sit-to-stand exercise (ISTS) with and without arm support compared with an incremental cycle-ergometer (CE) test; and 2) to examine the reproducibility of the AT measured duri...
