tract to a pasty consistency. Alcohol (80 per cent.) is then added and the mixture is centrifugalised and the active principle is obtained in alcoholic solution in the clear top layer. This is pipetted off and mixed with an excess of absolute alcohol in which the active principle becomes precipitated. The precipitate is then dissolved in sterile distilled water, concentrated by distillation in ...

Aluminum present in a beverages can affect the taste. This application note describes the determination of aluminum in beverages using an Agilent 4100 MP-AES. Beverages contain a variety of matrix constituents, including salt, sugar, and alcohol. A study was performed to determine how these matrix constituents affect aluminum measurements, and what could be done to reduce such effects. It was d...

The synthesis, characterization and biological assays of two new rhodium carboxylate sugar derivatives and respective cyclosphosphamide adducts are described. The compounds, characterized by (13)C and (1)H NMR, infrared and UV-visible spectra, presented high water solubility and hydration grades were confirmed given the concordance between thermal and CHN analyses. The adducts were active in vi...

OBJECTIVE To explore whether the effects on dietary behaviours of a computer-tailored intervention aimed to prevent excessive weight gain among adolescents, FATaintPHAT, were moderated by sociodemographic, cognitive and home environmental factors. DESIGN A two-group cluster randomized trial. Potential moderation of the outcome measures (consumption of sugar-sweetened beverages, snacks, fruits...

Previous studies of carbohydrate metabolism have been limited almost exclusively to naturally occurring saturated sugars. Very little attention has been devoted to the fate of the unsaturated and anhydro sugars in the organism. Even though these unsaturated sugars occur very rarely in nature, information concerning their fate in the body would be of value in determining the mechanism of sugar m...

Kinetic studies of the cooperative binding of glucose to yeast hexokinase P-I at pH 6.5 have been carried out using the fluorescence temperature-jump technique. Three relaxation effects were observed: a fast low-amplitude effect which could only be resolved at low glucose concentrations (tau 1(-1) = 500-800 s-1), an intermediate effect (tau 2) which showed a linear dependence of reciprocal rela...

The first SeO(2) induced (Z)-selective allylic alcohol formation of dialkyl alkylidenesuccinates has been demonstrated to accomplish one-step syntheses of several essential butenolides and fused butenolides via an unusual E- to Z- carbon-carbon double bond isomerisation followed by the lactonization pathway. The observed regio- and stereoselective SeO(2) allylic oxidation protocol has also been...

Benzylic acetates reacted with arylboronic acids in the presence of a DPEphos-[Pd(eta3-C3H5)Cl]2 catalyst when tert-amyl alcohol was used as a solvent, and the catalytic cross-couplings produced diarylmethanes in high yields (up to 94% isolated yield).

BACKGROUND There have been increases in the obesity and overweight rates in Australian children over the past 25 years and it has been suggested that sugar sweetened beverages (SSB) have played a role in this increase. OBJECTIVE The objectives of this study were to: (1) examine SSB intakes in the 2007 Australian Children's Nutrition and Physical Activity Survey (2) relate SSB intake to rates ...

BACKGROUND High physical activity, low sedentary behavior and low consumption of sugar-sweetened beverages can be markers of a healthy lifestyle. We aim to observe longitudinal changes and secular trends in these lifestyle variables as well as in the prevalence of overweight and obesity in 7-to-9-year-old schoolchildren related to gender and socioeconomic position. METHODS Three cross-section...
