Utilization of wheat straw for the preparation of coated controlled-release fertilizer with the function of water retention.
J. Agric. Food Chem. 60(28) , 6921-8, (2012) With the aim of improving fertilizer use efficiency and minimizing the negative impact on the environment, a new coated controlled-release fertilizer with the function of water retention was prepared. A novel low water solubility macromolecular fertilizer, po... |

Denaturation behavior of alpha-chymotrypsinogen A in urea and alkylurea solutions: fluorescence studies.
J. Protein Chem. 13(3) , 323-31, (1994) The solvent denaturation of alpha-chymotrypsinogen (alpha-ctg A) in aqueous solution of urea, methyl-, N,N'-dimethyl-, ethyl-, propyl- and butylurea was studied by fluorescence measurements. Data were analyzed on the assumption of a two-state approximation to... |

Effect of urea, dimethylurea, and tetramethylurea on the phase behavior of dioleoylphosphatidylethanolamine.
Chem. Phys. Lipids 114(2) , 149-57, (2002) The phase behavior of dioleoylphosphatidylethanolamine in aqueous solutions of urea, N,N'-dimethylurea (DMU), and N,N,N',N'-tetramethylurea (TMU) has been characterized by synchrotron X-ray diffraction and differential scanning calorimetry. All three solutes ... |

Apparent specific volumes of some dipeptides (containing L-valine and L-leucine in aqueous alkylurea solutions).
Int. J. Pept. Protein Res. 39(5) , 415-8, (1992) The apparent molal volumes of nine dipeptides containing glycine, L-valine, and L-leucine have been determined in methyl, N,N'-dimethyl and ethylurea solutions from precise density measurements. Limiting partial molal volumes. V2(0), at various solute concent... |

Effects of free radical scavengers on cytokine actions on islet cells.
Acta Endocrinol. 128(4) , 379-84, (1993) We investigated the effect of free radical scavengers on the actions of cytokines on islet cells. Interferon-gamma and tumor necrosis factor-alpha reduced the nicotinamide adenine dinucleotide content of mouse islet cells; the combination of interferon-gamma ... |

Mutagenicity of N,N'-dimethylurea and methylamine hydrochloride in the Ames Salmonella/microsome test: absence of mutagenic response.
Mutat. Res. 279(4) , 275-80, (1992) Methyl isocyanate (MIC) in aqueous solution forms methylamine (MA) and N,N'-dimethylurea (DMU). MA in buffered system further converts into its salt form, methylamine hydrochloride (MAH). Therefore, MAH and DMU were evaluated for their mutagenic activity in t... |

Eugenol causes oxidant-mediated edema in isolated perfused rabbit lungs.
Am. Rev. Respir. Dis. 143(4 Pt 1) , 806-9, (1991) Eugenol, an extract of cloves, has been associated with pulmonary edema when inhaled from commercially available clove cigarettes. We tested the hypothesis that eugenol directly causes lung edema through oxidant-mediated mechanisms by infusing eugenol (0.1 an... |

In vitro and in vivo effect of methyl isocyanate on rat liver mitochondrial respiration.
Toxicol. Appl. Pharmacol. 117(2) , 172-9, (1992) Previous work has shown that irrespective of the route of exposure methyl isocyanate (MIC) caused acute lactic acidosis in rats (Jeevaratnam et al., Arch. Environ. Contam. Toxicol. 19, 314-319, 1990) and the hypoxia was of stagnant type due to tissue hypoperf... |

Comparative toxicity of methyl isocyanate and its hydrolytic derivatives in rats. I. Pulmonary histopathology in the acute phase.
Arch. Toxicol. 69(1) , 39-44, (1994) The present study describes the acute histopathological changes induced by methyl isocyanate (MIC) in the lungs of rats at 24 h after a single exposure to varied concentrations/doses of MIC by inhalation and subcutaneous (s.c.) routes and also delineates the ... |
