EARLY analyses of the proteins of the normal aqueous humour by Franceschetti and Wieland (1928), and later by Kronfeld (1941) and Kronfeld and others (1941), have shown a content of 10 to 20 mg. per cent. Any functional significance this protein may have is unknown. However, the human lens contains 30-40 p' r cent. protein, the fractions of which have been determined by several authors (Cagianu...

the three components one pot synthesis of 2-amino-4h-benzo-[b] -pyran derivatives were obtained in good to excellent yields within short reaction time by condensing dimedone, aldehydes and malanonitrile or ethylcyanoacetate using a catalytic amount of (diacetoxyiodo)benzene as hypervalent iodine in aqueous ethanol under reflux conditions have been discussed. this aqua mediated knoevenagel-cyclo...

Nanocomposite of polyaniline (PAn) containing nanometre size Sb2O3 was prepared in aqueous media in situ chemical oxidative polymerization method at room temperature in the presence of hydroxypropylcellulose (HPC) as a surfactant. The ability of product to removal of lead ions from aqueous solution was studied. The chemical structure and morphology were studied by fourier transform infrared (FT...

Vinyl(aryl)iodonium salts are useful compounds in organic synthesis but they are under-utilized and their chemistry is under-developed. Herein is described the solvolysis of some vinyl(phenyl)iodonium salts, bearing an arylsulfonyl group, in aqueous DMSO leading to aldehyde formation. This unusual process is selective and operates under ambient conditions. Furthermore, the addition of aqueous H...

After gamma irradiation of cytosine in aerated aqueous solution, yields of chemical radiation products belonging to the deamination pathway were measured. Primary stable radiolysis products, such as 5,6-dihydroxy-5,6-dihydro-uracil cis and trans forms, were present with G values lower than those obtained in the radiolysis of uracil irradiated under the same conditions. Cytosine had Gamma Irradi...

The hybrid semiconducter-macrocycle catalyst TiO2-cobalt phthalocyanine promotes the solar photolysis of aqueous bromoform under anaerobic conditions. The major decomposition products are dibromoethane and HBr. Bromomethane and methane were produced only after prolonged photolysis (30 hr). Acetone, derived from added 2-propanol, was the only observed oxidation product. Preliminary experiments s...

A unique boronate-functionalized SiO2/TiO2 hybrid monolithic column was synthesized by a facile approach. Although a conventional boronic acid, 4-vinylphenylboronic acid, was used as the affinity ligand, the prepared monolithic column exhibited specific capacity to capture glycoproteins including antibodies in aqueous solution at neutral pH. With the incorporation of titania, the monolith was h...

4-Hydroxy-3-methoxymandelic acid (HMMA) concentrations in aqueous humour, urine, and serum were simultaneously estimated to determine if these levels were raised in cases of retinoblastoma. The catecholamine content of aqueous humour was significantly higher than that of urine and serum, but as there was no significant difference in the HMMA concentration in retinoblastoma and other non-maligna...

in this study, the removal of cadmium and lead ions from aqueous solution by nanocrystalline magnetite was investigated. the nanocrystalline magnetite was synthesized by mechanochemical activation of hematite in a high energy planetary mill in argon atmosphere for 45 hours. the ability of the synthesized nanocrystalline magnetite for removal of cd(ii) and pb(ii) from aqueous solutions was studi...
