Herein, the impact of chemical stability RedOx mediator ferricyanide, K3[Fe(CN)6] (FC), a type buffer solution used for bioreceptor preparation, gel composition (carboxymethylcellulose, CMC, Aerosile, AS, and alginate, ALG) on long term glucose test-strips their analytical performance was examined. By simple addition ALG to functional aiming improve its viscosity, we managed enhance sensitivity...

Two forms of rabbit factor VIII procoagulant activity, distinguishable by size on gel filtration and ultracentrifugation, have been identified in normal rabbit plasma. These studies have been carried out with citrate-anticoagulated rabbit plasma obtained by cardiac puncture. Two peaks of factor VIII activity were obtained on agarose gel chromatography, using physiologic ionic strength buffers: ...

OBJECTIVE To determine the effects of phosphocreatine (PCr) depletion on myocellular energetics. DESIGN Randomized controlled study. SETTING University laboratory. MATERIALS Thirty-eight adult male Wistar rats (110-121 g). METHODS The poorly metabolized creatine analogue beta-guanidinopropionic acid, (beta-GPA, 2% of a gel diet) was fed to the rats for 14 days to replace (75%) endogenou...

It was shown that feuB mutants (defective in ferric enterochelin uptake) were unable to adsorb colicin B. In addition, they were missing one of the three outer-membrane proteins which are over produced in strains grown in iron-deficient, extracted medium. Thus this protein (the feuB protein) is probably the receptor for colicin B and functions in enterochelin-mediated iron transport. The feuB g...

4-amino methyl pyridine anchored silica gel (4-AMPS) was used as a sorbent in a simple sensitive spectrophotometry determination of Cu (II) in various samples using piperazine dithiocarbamate as a color developing agent (λmax 420 nm) at pH 5.0 ± 0.2. Beer’s law was obeyed over the range of 0.2 -13 μg ml-1. The molar absorptivity and Sandell’s sensitivity were 0.5731 × 105 l mol-1cm-1 and 0.0022...

BACKGROUND AND AIMS Aluminium (Al) stimulates the efflux of citrate from apices of rice bean (Vigna umbellata) roots. This response is delayed at least 3 h when roots are exposed to 50 microm Al, indicating that some inducible processes leading to citrate efflux are involved. The physiological bases responsible for the delayed response were examined here. METHODS The effects of several antago...

Background: One of the most common causes of infertility in women is ovulatory dysfunction (PCOS) and the choice of treatment is clomiphene citrate. One of the mechanism of dichotomy between the rate of ovulation and pregnancy is anti estrogenic effects of clomiphene citrate on endometrium. According to its long half life, the anti estrogenic effects probably exacerbate in consecutive cycles. W...

This study presents synthesis results of catalysts made perovskite-like oxide La2-xSrxCuO4 (x=0.0, 0.5, 1.0) using the citrate method and crystallisation at 800°C. The structure was characterised by X-ray diffraction (XRD). catalyst activity enhanced with gold (Au) platinum (Pt). Au mounted on sol-gel method. perovskite LaMnO3/LaCuO3 evaluated complete oxidation volatile hydrocarbons (HCs) in a...
