This study investigates the effects of two feeding systems and two dairy cow breeds on milk yield and composition, physical and sensorial properties of Camembert and Pont-l'Evêque cheeses. The experiment consisted of a 2 × 2 factorial arrangement of treatments. A low energy grass diet with only 15% of concentrate (LowGS) was compared with a high-energy maize silage diet with 30% concentrate (Hi...

The concentrations of total polycyclic aromatic hydrocarbons (sigmaPAHs) and 15 individual PAH compounds in 20 surface sediments collected from four mangrove swamps in Hong Kong were analysed. sigmaPAH concentrations ranged from 356 to 11,098 ng g(-1) dry weight with mean and median values of 1992 and 1,142 ng g(-1), respectively. These values were significantly higher than those of marine bott...

BACKGROUND Staphylococcus aureus bacteremia (SAB) is a serious cause of morbidity and mortality. This longitudinal study describes significant reductions in hospital-onset SAB (HO-SAB) in Australian hospitals over the past 12 years. METHODS An observational cohort study design was used. Prospective surveillance of HO-SAB in 132 hospitals in Australia was undertaken. Aggregated data from all p...

Polybrominated diphenyl ethers (PBDEs) are used in large quantities as additive flame retardants in plastics and textile materials. PBDEs are persistent compounds and have been detected in wildlife and in human adipose tissue and plasma samples. In this study, we investigated the (anti)estrogenic potencies of several PBDE congeners, three hydroxylated PBDEs (HO-PBDEs), and differently brominate...

If N-G1O-AAF were involved in the mechanism of action of AAF in species susceptible to carcinogenesis by AAF, then one would also expect N-GbO-AAF to be carcinogenic. In a prelimi nary test, carried out at bow dose because of the limited availa biity of N.GbO-AAF, tumor development did not occur within 12 months after repeated subcutaneous injections of either the sodium or cupric salts, or of ...

Rational combination of pyridazine, hydroxo and carboxylate bridging ligands led to the assembly of three types of mixed-ligand polynuclear Cu(II) clusters (A: [Cu2(μ-OH)(μ-pdz)(μ-COO)]; B: [Cu4(μ3OH)2(μ-pdz)2]; C: [Cu5(μ-OH)2(μ-pdz)4(μ-COO)2(μ-H2O)2]) and their integration into 3D framework structures. Mixed-ligand complexes [Cu2(μ-OH){TMA}(L)(H2O)] (1), [Cu4(μ3-OH)2{ATC}2(L)2(H2O)2]·H2O (2) [...

Disparity cues affect a subject’s ability to detect movement only when stimulusoscillation frquency is less than 1 Hz. Disparity cues then increase sensitivity for targets closeto the fixation plane (within 7.5’), but decrease sensitivity for targets whose disparities aregreater. Binocular sensitivity to sideways movement is higher for targets in the fizxation planethan for targ...

Heme oxygenase (HO) catalyzes the O2 and NADPH/cytochrome P450 reductase-dependent conversion of heme to biliverdin, free iron ion, and CO through a process in which the heme participates as both dioxygen-activating prosthetic group and substrate. We earlier confirmed that the first step of HO catalysis is a monooxygenation in which the addition of one electron and two protons to the HO oxy-fer...

The electrochemical oxidation of anodic metals (M = cobalt, nickel, copper, zinc and cadmium) in a solution of the ligand 1H-anthra[1,2-d]imidazol-6,11-dione-2-[2-hydroxyphenyl] [H2L] afforded homoleptic [ML] compounds. The addition to the electrochemical cell of coligands (L') such as 2,2'-bipyridine (bpy) or 1,10-phenanthroline (phen) allowed the synthesis, in one step, of heteroleptic [MLL']...

Dysregulation of matrix metalloproteinase (MMP) activity can lead to a wide range of disease states such as atherosclerosis, inflammation or cancer. The ability to image MMP activity non-invasively in vivo, by radiolabelled synthetic inhibitors, would allow the characterization of atherosclerotic plaques, inflammatory lesions or tumors. Here we present an overview of radiolabelled MMP inhibitor...
