Background: In single photon emission computed tomography [SPECT], high specific activity of In-labelled tracers will allow administration of low amounts of tracer to prevent receptor saturation and/or side effects. To increase the specific activity, we studied the effect of the buffer used during the labelling procedure: NaAc, NH4Ac, HEPES and MES buffer. The effect of the ageing of the InCl3 ...

In their study of a quartic integral, Boros and Moll discovered a special class of Jacobi polynomials, which we call the Boros-Moll polynomials. Kauers and Paule proved the conjecture of Moll that these polynomials are logconcave. In this paper, we show that the Boros-Moll polynomials possess the ratio monotone property which implies the log-concavity and the spiral property. We conclude with a...

OBJECTIVE The aim of this study was to assess the oral dryness in postmenopausal women and to correlate the salivary flow rate determined by sialometry with the clinical oral dryness score (CODS) obtained from Challacombe Scale. To correlate between subjective and objective oral dryness and relationship of salivary flow rate with that of the duration of menopause. MATERIALS AND METHODS Sixty ...

A mixture of acrylamide (AAm) and methacrylic acid (MAA) was crosslinked onto Gum ghatti (Gg) using N, N’-methylene-bis-acrylamide (MBA) as a crosslinker and ascorbic acid (ABC) and potassium persulphate (KPS) redox pair as an initiator. Optimized reaction parameters for the graft copolymerization of Gum ghatti with AAm were time (min)=90; temperature (C)=50; pH=7.0; deionized water (ml)=10; mo...

The first C(60)(OH)(24)-DNA complex and its fluorescence enhancement is reported. The enhanced fluorescence intensity of fullerenol C(60)(OH)(24) is in proportion to the concentration of DNA in the range of 1 x 10(-9) to 8 x 10(-5) molL(-1) and the detection limit was 1.3 ng mL(-1). Fullerenol C(60)(OH)(24) binds significantly to the phosphate backbone of native dsDNA and to base-pairs within t...
