Despite extensive growth in recent years, the field of "quality-of-life" appraisal still evokes debate about basic perception of the concept and is accompanied by a plethora of indexes for measurement. One prime reason for the problems is that the measurements have been transferred from two separate sources - medical health status indexes and social-science population indexes - neither of which...

Considerable attention has been devoted to environmental assessment and monitoring, primarily by physical and biological scientists, and more recently by social scientists. However, population growth and global change have resulted in an imperative to assess the resiliency of the environment to adapt to large scale changes and to continue to produce goods and services for future generations (su...

the purpose of this investigation was to develop a simple colorimetric method for creatine kinase (ck). the new method is based on the reaction of creatine, formed enzymatically from creatine phosphate and adp, with different glyoxal compounds. hydrated glyoxals, such as para-nitrophenyl, 2-thiophene, 4- biphenyl, 4, 4' -biphenyl,α-naphthyl, β-naphthyl, para-chlorophenyl, and styryl were s...

Three fluorescent dyes (a merocyanin, a cyanin and a modified umbeliferon) have been incorporated into vesicles from three different lecithins. Their absorption spectrum, emission spectrum and fluorescence polarization in the lipid vesicles has been studied and compared with the spectral properties in homogeneous organic solutions. The reactivity of lipid bound dyes with reagents in the aqueous...

purification and isolation of cellular target proteins for monoclonal antibody (mab) production is a difficult and time-consuming process. immunization of mice with murine cell lines stably transfected with genes coding for xenogenic target molecules is an alternative method for mouse immunization and mab production. here we present data on transfection efficiency of some commercial reagents us...

This entry describes applications of known indicators and dyes as new visualizing reagents and various visualizing systems as well as photocatalytic reactions and bioautography method for the detection of bioactive compounds including drugs and compounds isolated from herbal extracts. Broadening index, detection index, characteristics of densitometric band, modified contrast index, limit of det...

Large reserves of coal in Tabas region of Iran are characterized by low ash and high caking index, suitable for use in metallurgy as coking coal. However, these coals cannot be gainfully utilized because of their high sulfur content. In this work, studies on desulfurization of Tabas coals were carried out in a batch reactor using various reagents. The most effective reagents,<...

new, simple and cost effective spectrophotometric methods have been developed for the quality assessment of isoniazid (inh), in bulk and in pharmaceutical formulations by using novel reagents. the proposed methods involve the utility of ethyl 2-[(e)-(4-hydroxyphenyl) diazenyl]-3-oxobutanoate and benzil as novel reagents for the determination of inh. developed methods are based on the condensati...
