Bismuth nanoparticles integration into heavy metal electrochemical stripping sensor.
Electrophoresis , doi:10.1002/elps.201400609, (2015) Between their many applications bismuth nanoparticles (BiNPs) are showing interest as pre-concentrators in heavy metals detection while being applied as working electrode modifiers used in electrochemical stripping analysis. From the different reported method... |

Effect of irrigation with Tetraclean on bacterial leakage of obturated root canals.
N. Y. State Dent. J. 80(3) , 39-43, (2014) The purpose of the study presented here was to evaluate the effect of Tetraclean, Hypoclean, Chlor-XTRA, 2% chlorhexidine and 6% sodium hypochlorite/17% EDTA as a final irrigant on bacterial leakage of the root canal. One hundred and fifty-five extracted huma... |

Hybrid nanoprobes of bismuth sulfide nanoparticles and CdSe/ZnS quantum dots for mouse computed tomography/fluorescence dual mode imaging.
J. Nanobiotechnology 13 , 76, (2015) X-ray computed tomography (CT) imaging can be used to reveal the three-dimensional structure of deep tissue with high spatial resolution. However, it cannot reveal molecular or cellular changes, and has great limitations in terms of specificity and sensitivit... |

Hydrogen sulfide production from subgingival plaque samples.
Anaerobe 35 , 21-7, (2015) Periodontitis is a polymicrobial anaerobe infection. Little is known about the dysbiotic microbiota and the role of bacterial metabolites in the disease process. It is suggested that the production of certain waste products in the proteolytic metabolism may w... |

Diagnostic use of cerebral and extracerebral oxysterols.
Clin. Chem. Lab Med. 42(2) , 186-91, (2004) 24S-Hydroxycholesterol (24OHC) and 27-hydroxycholesterol (27OHC) are two structurally similar oxysterols of different origins--the former almost exclusively formed in the brain and the latter formed to a lesser extent in the brain than in most other organs. H... |

Levels of 7-oxocholesterol in cerebrospinal fluid are more than one thousand times lower than reported in multiple sclerosis.
J. Lipid Res. 46(2) , 191-5, (2005) In a recent publication [Diestel, A., O. Aktas, D. Hackel, I. Hake, S. Meier, C. S. Raine, R. Nitsch, F. Zipp, and O. Ullrich. 2003. Activation of microglial poly (ADP-ribose)-polymerase-1 by cholesterol breakdown products during neuroinflammation: a link bet... |

Disruption of thiol homeostasis and nitrosative stress in the cerebrospinal fluid of patients with active multiple sclerosis: evidence for a protective role of acetylcarnitine.
Neurochem. Res. 28(9) , 1321-8, (2003) Recent studies suggest that NO and its reactive derivative peroxynitrite are implicated in the pathogenesis of multiple sclerosis (MS). Patients dying with MS demonstrate increased astrocytic inducible nitric oxide synthase activity, as well as increased leve... |

Folate and methylation status in relation to phosphorylated tau protein(181P) and beta-amyloid(1-42) in cerebrospinal fluid.
Clin. Chem. 53(6) , 1129-36, (2007) Increased plasma total homocysteine (tHcy) is a risk factor for neurological diseases, but the underlying pathophysiology has not been adequately explained.We evaluated concentrations of tHcy, S-adenosyl homocysteine (SAH), S-adenosyl methionine (SAM), folate... |

Serum uric acid levels in multiple sclerosis patients correlate with activity of disease and blood-brain barrier dysfunction.
Eur. J. Neurol. 9(3) , 221-6, (2002) Several findings suggest lower levels of serum uric acid in multiple sclerosis (MS) patients. The aim of this study is to investigate relationships of uric acid serum levels in relapse-remitting (RR) MS patients with clinical activity of disease and blood-bra... |

Inflammatory multiple-sclerosis plaques generate characteristic metabolic profiles in cerebrospinal fluid.
PLoS ONE 2(7) , e595, (2007) Multiple sclerosis (MS), an inflammatory disease of the central nervous system, manifests itself in numerous forms and stages. A number of brain metabolic alterations have been reported for MS patients vs. control subjects. However, metabolite profiles of cer... |
