phosphoryl containing ligand tri-n-octylphosphine oxide (topo) in dichloromethane has been used as an extracting agent for tetravalent thorium and trivalent europium ions from their 1 m sodium nitrates. the equilibrium data reveal that both ions are extracted as the complexes at 1:3 metal/ligand ratio. the values of conditional extraction equilibrium constant (kex) show the superior extractive ...

the aim of the study was to evaluate the clinical usefulness of n-terminal pro-brain natriuretic peptide (nt-pro bnp) and nitric oxide (no) with echocardiography (gold standard test) in diagnosis of canine cardiomyopathy. out of 374 cases, 82 cases showing cardiovascular abnormalities including 16 cases of cardiomyopathy were further selected for standardization of biomarkers. significant (p
