Non-stabilized nucleophiles in Cu-catalysed dynamic kinetic asymmetric allylic alkylation.
Nature 517(7534) , 351-5, (2015) The development of new reactions forming asymmetric carbon-carbon bonds has enabled chemists to synthesize a broad range of important carbon-containing molecules, including pharmaceutical agents, fragrances and polymers. Most strategies to obtain enantiomeric... |

ROI-SCAVENGING ENZYME ACTIVITIES AS TOXICITY BIOMARKERS IN THREE SPECIES OF MARINE MICROALGAE EXPOSED TO MODEL CONTAMINANTS (COPPER, IRGAROL AND ATRAZINE)
Ecotoxicol. Environ. Saf. 104 , 294-301, (2014) There is a need to develop efficient tools to prevent damage to marine ecosystems due to pollution. Since microalgae play a key role in marine ecosystems, they are considered potentially useful for quick and sensitive toxicity bioassays. In this study an inte... |

Influence of the selective EDTA derivative phenyldiaminetetraacetic acid on the speciation and extraction of heavy metals from a contaminated soil.
Chemosphere 109 , 1-6, (2014) The development of more selective chelators for the washing of heavy metal contaminated soil is desirable in order to avoid excessive dissolution of soil minerals. Speciation and mobility of Cu, Zn, Pb, and Ni in a contaminated soil washed with phenyldiaminet... |

Synergistic effects of TiO2 and Cu2O in UV/TiO2/zeolite-based systems on photodegradation of bisphenol A.
Environ. Technol. 35(13-16) , 1851-7, (2014) In this study, TiO2/zeolite (TZ)-based composite was utilized to degrade bisphenol A (BPA) under ultraviolet (UV) irradiation. The effects of the TiO2 and Cu2O doses in TZ and Cu2O/TiO2/zeolite (CTZ) on the rate of BPA removal were identified, respectively. T... |

Physiological responses of biomass allocation, root architecture, and invertase activity to copper stress in young seedlings from two populations of Kummerowia stipulacea (maxim.) Makino.
Ecotoxicol. Environ. Saf. 104 , 278-84, (2014) In the current study, we hypothesize that mine (metallicolous) populations of metallophytes form a trade-off between the roots and shoots when under copper (Cu) stress to adapt themselves to heavy metal contaminated habitats, and thus, differ from normal (non... |

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... |
