Bis(maltolato)oxovanadium(IV) (BMOV), and its ethylmaltol analog, bis(ethylmaltolato)oxovanadium(IV) (BEOV), are candidate insulin-enhancing agents for the treatment of type 2 diabetes mellitus; in mid-2008, BEOV advanced to phase II clinical testing. The interactions of BMOV and its inorganic congener, vanadyl sulfate (VOSO(4)), with human serum(More)
The interaction of cetyl trimethylammonium bromide (CTAB) with alpha-amylase from Bacillus subtilis was investigated at 25 degrees C and various experimental conditions, such as pH, ionic strength and urea concentration. The binding data were measured using CTAB-membrane selective electrodes as a simple, fast, cheap and accurate method. The obtained binding(More)
Biodegradation of lignocellulosic waste by Aspergillus terreus is reported for the first time. This isolate produced 250 CMCase (carboxymethyl cellulase or endoglucanase) U.ml-1 and biodegraded hay and straw during 3 days and the biomass production on straw was 5g.L-1dry weight from 0.25 cm2 inoculated mycellium. This strain secreted endocellulases and(More)
Bovine serum albumin (BSA) denaturation has been extensively studied by different anionic and cationic surfactant. Dodecyl trimethylammonium bromide (DTAB) is a cationic surfactant, and it is suggested that it binds to the C-terminal section of BSA. In the present study, the thermodynamical denaturation of BSA by dodecyl trimethylammonium bromide (DTAB) has(More)
The ctDNA-binding properties and in vitro antitumor activity of three water soluble Keggin type polyoxometalates (POMs): K6H[CoW11O39CpZr]·nH2O, K6H[CoW11O39CpTi·nH2O and K7H2[CoW11O39CpFe]·nH2O (abbreviated as CoWCpZr, CoWCpTi and CoWCpFe, respectively) were investigated using UV-Vis absorption spectroscopy, fluorescence spectrophotometry, cyclic(More)
The current study reports the binding of curcumin (CUR) as the main pharmacologically active ingredient of turmeric and diacetylcurcumin (DAC) as a bioactive derivative of curcumin to human serum albumin (HSA) and bovine serum albumin (BSA). The apparent binding constants and number of substantive binding sites have been evaluated by fluorescence quenching(More)
Magnetite Fe3O4 nanoparticles (NPs) were prepared by chemical coprecipitation method. Silica-coated magnetite NPs were prepared by sol-gel reaction, subsequently coated with 3-aminopropyltriethoxysilane (APTES) via silanization reaction, and then were activated with 2,4,6-trichloro-1,3,5-triazine (TCT) and covalently immobilized with bovine serum albumin(More)
beta-Lactoglobulin (beta-LG) is one of the cow's major milk proteins and the most abundant whey protein. This globular protein of about 18 kDa is folded, forming a beta-barrel (or calyx) structure. This structure is stabilized by two disulfide bonds and can be altered by heating above 65 degrees C. beta-LG is also one of the major allergens in milk. Heating(More)
The binding of curcumin (CUR) and diacetylcurcumin (DAC) to bovine beta-lactoglobulin (BLG) genetic variant B was investigated by fluorescence and circular dichroism techniques. The binding parameters including number of substantive binding sites and the binding constants have been evaluated by fluorescence quenching method. The distance (r) between donor(More)
β-Lactoglobulin (β-LG) is a lipocalin, which is the major whey protein of cow's milk and the milk of other mammals. However, it is absent from human milk. The biological function of β-LG is not clear, but its potential role in carrying fatty acids through the digestive tract has been suggested. β-LG has been found in complexes with lipids such as butyric(More)
