Ceftriaxone penetrates into the aqueous humour in man. The interaction of indomethacin on the disposition of ceftriaxone appeared to be time-dependent. Indomethacin delayed ceftriaxone penetration into, but enhanced its persistence in, the aqueous humour, permitting a period of antibioprophylaxis covering the required time for surgical treatment.
nabro3 combined with nh4cl is found to be an efficient reagent for the transformation of sulfides into sulfoxides in aqueous and under mild conditions.
The main types of analytical procedures used in thermal-lens spectroscopy and microscopy, which are based on photometric reactions in (i) aqueous solutions, (ii) organo-aqueous mixtures, (iii) polymer-containing (nonionic surfactants or polyethylene glycol) aqueous solutions, (iv) water-organic extraction systems, and (v) two-phase aqueous extraction systems, were compared from the viewpoint of...
In the present work, the procedures for the creation of self-assembled DNA nanostructures in aqueous and non-aqueous media are described. DNA-Surfactant complex formation renders the DNA soluble in organic solvents offering an exciting way to bridge the transition of DNA origami materials electronics applications. The DNA retains its structural features, and these unique geometries provide an i...
the present paper concerns on the selective and very efficient transport of thorium(iv) ions from aqueous solutions through an emulsion liquid membranes composed by paraffin and a surfactant, without carrier requirement. the influence of ph of the external aqueous phase, the surfactant concentration in the membrane phase, the type, and concentration of the acid used in the receiving phase, the ...
abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
Previous work on the vitamin B12 content of the aqueous humour (Phillips, Ainley, van Peborgh, Watson-Williams, and Bottomley, I968) suggests that the levels found in a series of mainly elderly patients (mean: 299 pg./ml.) are of the same order as those found in cerebrospinal fluid (mean: 21 pg./ml.) (Kidd, Gould, and Thomas, I963). As an extension of this study, the response of aqueous vitamin...
