Gels can be formed by dissolving Fmoc-diphenylalanine (Fmoc-PhePhe or FmocFF) in an organic solvent and adding water. We show here that the choice and amount of organic solvent allows the rheological properties of the gel to be tuned. The differences in properties arise from the microstructure of the fibre network formed. The organic solvent can then be removed post-gelation, without significan...

The FCGR3A gene dimorphism generates two allotypes: FcgammaRIIIa-158V and FcgammaRIIIa-158F. The genotype homozygous for FcgammaRIIIa-158V (VV) is associated with higher clinical response to rituximab, a chimeric anti-CD20 IgG1 used in the treatment of B lymphoproliferative malignancies. Our objective was to determine whether this genetic association relates to rituximab-dependent cytotoxicity ...

The sequential QM/MM methodology is used to describe the solvent effects on the electronic absorption spectra of organic molecules in solution. The structure of the liquid is generated by Monte Carlo computer simulation. Configurations composed by the solute and several solvent molecules are selected for a posteriori quantum mechanical calculations of the spectra. Situations are considered wher...

The present investigation was carried out to evaluate the antibacterial activity of leaf and root silver nanoparticles synthesized using different solvents. According our studies AgNPs Strychons nux vomica from solvent extract revealed possess significant comparing exhibited by extract. Among AgNPS tested, ethyl acetate showed highest inhibitory acetone methanol extracts. based zone inhibition ...

freshly prepared zno nanoparticles were used as an effective heterogeneous base catalyst for the synthesis of aryloximes. the conversion of arylaldehydes and arylketones into the corresponding oximes (up to quantitative yields) was achieved by simply mixing the liquid reactants and hydroxylamine hydrochloride with zno nanoparticles under solvent-free condition. the procedure was carried out und...

The aim of this study was to develop an efficient enzymatic glycerolysis system together with physical fractionation operation for the production of monoacylglycerols (MAG) containing polyunsaturated fatty acids (PUFA), especially, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) from tuna oil. The enzymatic glycerolysis system at 40-70 °C is unfortunately a multiple-phase system, whi...

The therrmodynamic parameters and equilibrium constant of displacement of dimethy sulfide by 3-carboaldehyde pyridine as N-donor ligand in cis-[Pt(4-MeC6H4)2(SMe2)2] complex have been measured using UV vis spectroscopy in acetone, dichloromethane and benzene at various temperatures (T=15-20 °C) and compared with previous my reported about similar reaction. ΔHo (KJ.mol-1) of the mentioned reacti...

WHinE the presence of small amounts of choline and acetylcholine can easily be detected by biological methods, their quantitative micro-chemical estimation presents considerable difficulty. The only method hitherto described for the micro-chemical estimation of choline appears to be that of Roman [1930], a modification of the macro-method of Stanek [1906] depending on the precipitation of choli...

RESEARCH project at this laboratory involved the A accurate determination of the carotene content of many samples of fresh and dehydrated vegetable products. (Carotene referred to in this paper includes both alphaand betacarotene, in most cases approximately 10 per cent alpha and 90 per cent beta.) The methods commonly used a t present for the determination of carotene in plant materials depend...
