1. Methods for the concentration of Type I pneumococcus antibody have been outlined. 2. The physical and chemical properties of the purified antibody have been described. 3. The chemical basis of serological specificity has been discussed.

  ABSTRACT In order to evaluate time course of changes in serum concentration of thyroid hormones, cortisol and ACTH in patients exposed to chemical weapons containing sulfur mustard, we measured serum concentrations of hormones on the first, third and fifth week following injury in 13 soldiers and compared them to the results obtained from 34 control men. Free T4 and T3 indices were decrease...

Background & objectives: Pharmaceutical wastewater contains high concentrations of organic matter, high salt and difficult biodegradability, so it must be treated before discharge to the environment. In this study, it is aimed to evaluate the treatment of pharmaceutical wastewater (methadone feedstock and neutralized capecitabine) using chemical and biological methods. Methods: The laboratory ...

returning crop residues into the soil as a source of organic matter are an important source of copper and can play an important role in the soil fertility. in addition to the role of the organic matter in increasing the concentration of micronutrients in soil solution, attention should be also paid to the role of the kind and the quantity of the root’s exudates released in response to the incor...

Research Highlights  Concentration of odorous substances as surrogate for odour concentration/intensity  Comparison of conversion methods with various degrees of complexity  Model evaluation by seven VOCs: 23 binary mixtures and 5 mixtures of 7 substances  Model input: odour threshold concentration and the slope of the Weber-Fechner law  No further calibration by olfactometric measurements...

background:a critical environmental impact of the petroleum industry is the contamination of soil by oil and other related products which are highly toxic and exhibit molecular recalcitrance. therefore, this study focused on investigating the total amount of petroleum hydrocarbons (tphs) in soil of urban fuel stations in hamedan city, iran. methods:thirteen high traffic urban fuel stations were...

Here, we present a sub-μm multimodal approach to image essential elements in Caenorhabditis elegans. A combination of chemical imaging technologies reveals total metal concentration, chemical state and the protein to which an element is associated. This application of distinct yet complementary chemical imaging techniques provided unique insight into essential and trace elements at the subcellu...
