Orientated ferromagnetic Ni0.89Fe0.11 nanoparticle/polymer nanofibres were made by electrospinning a solution containing iron(III) nitrate nonahydrate, nickel(II) acetate tetrahydrate, polyvinylpyrrolidone, and acetic acid in methanol thermally processed Ar then 95%Ar:5%H2 up to 620 °C. There was distribution nanofibre widths after with wider (average width 440 nm) some thinner 120 nanofibres. ...

saffron is an important spice values for its color, aroma and flavor in the food industry. a significant proportion of saffron compound is lost during processing and storage because of its volatility and sensitivity to oxidation. thepresent research microencapsulated saffron color compounds (crocin) by freeze drying. the freeze-dried aqueous saffron effective compound extract was first prepared...

Both C57BL/6 and BALB/c mice were immunized intravenously with lipopolysaccharide (LPS, 10 micrograms/mouse) on day 0, and hemolytic plaque forming cells (HPFC) in the spleen were assayed on day 4. Traxanox given orally at a dose of 30 mg/kg augmented the HPFC production to LPS in both mice. This agent (3-30 mg/kg) restored significantly the suppressed HPFC production to LPS in the BALB/c mice ...

Itraconazole (ITZ) solid complex using hydroxypropyl-beta-cyclodextrin (ITZ-HP-beta-CD) with 20% polyvinylpyrrolidone was prepared by a co-evaporation method. The complex improved antifungal activity against C. parapasilosis and C. albicans. The complex demonstrated good flow and compressibility characteristics. The complex was formulated as a capsule dosage form and drug release was evaluated....

We studied the effectiveness with which various charcoal preparations separate free [3H]pteroylglutamate from that complexed with milk folate binder. We tested, in various concentrations, uncoated charcoals and charcoals coated with dextrans of various molecular weights, or with albumin, hemoglubin, or polyvinylpyrrolidone with an average molecular weight of 40 000. Althouth there was some dist...
