The effect of granulocyte-macrophage colony stimulatory factors (GM-CSF), acidic isoferritins, and E-type prostaglandins on the detection of the cycle status of human granulocyte-macrophage progenitor cells (CFU-GM) was investigated. Bone marrow cells were pulse-treated with control medium or high specific activity tritiated thymidine [3HTdr) and subsequently plated over feeder layers containin...

Abstract Synthesis of water‐soluble‐substituted pyridinium cation which is attached with base sensitive fluorophore peripheral units different inorganic counter anions under conventional/silica‐supported Muffle furnace methods. Solvent‐free synthetic approach has more merits than the conventional method, such as non‐toxic, shorter reaction time, easy workup procedure without purification proces...

Kinetics of oxidation of L-citrulline (Cit) by permanganate ion in both acidic and basic media has been investigated spectrophtometrically at constant ionic strengths and at 25°C. In both media the reactions exhibited first order dependence in [permanganate] and less than unit order dependences in L-citrulline concentration. A fractional-second order dependence with respect to [H + ] and a frac...

The electrochemical oxidation behavior of m-nitrophenol (m-NP) was studied comparatively on glassy carbon electrode, Pt electrode, PbO2 electrode, SnO2 electrode, and graphite electrode using cyclic voltammetry. The cyclic voltammetry measurements were performed in acidic (1 M H2SO4, pH 0.4), neutral (1 M Na2SO4, pH 6.8), and...

A combined experimental and theoretical approach is used to define astatine (At) speciation in acidic aqueous solution and to answer the two main questions raised from literature data: does At(0) exist in aqueous solution and what is the chemical form of At(+III), if it exists. The experimental approach considers that a given species is characterized by its distribution coefficient (D) experime...
