Article: A growing body of evidence links personal behaviors to many chronic diseases and increased mortality (1, 2). The 1979 U.S. surgeon general's report (3) identified the following behavioral changes as desirable to promote health in the American population: elimination of smoking; decreased consumption of alcohol, excess calories, saturated fat, cholesterol, salt, and sugar; increased exe...

• A large impact on population health (i.e. >100,000 DALYs prevented per intervention) can be achieved by a limited number of cost-effective interventions: taxation of tobacco, alcohol and unhealthy foods; regulating the salt content of processed food; improving the efficiency of blood pressureand cholesterollowering drugs; gastric banding for severe obesity; and an intensive SunSmart campaign.

This paper looks at the theoretical development of a natural preservative system using a data base on medicinal plants as a source of reference. The legal aspects of this concept are considered. The traditional methods of preservation, many taken from the food industry are summarised. The use of alcohol, glycerine, sugar, salt, dessication, anhydrous systems and temperature are amongst examples...

The new Ru(IV) salt, [Ru(eta(3)-C(3)H(5))(Cp*)(CH(3)CN)(2)](PF(6))(2), is an excellent catalyst for the regioselective allylation of a variety of indole compounds using allyl alcohol as substrate; there are no co-catalysts required in this chemistry and the yields and reaction conditions are very favorable.

A unique supramolecular helix assisted by water tetramers is obtained by static evaporation of aqueous solution of a zwitterionic salt, 1,1'-bis(4-carboxylatebenzyl)-4,4'-bipyridinium; spontaneous chiral symmetry breaking occurs in crystallization; interestingly, redox chromism behavior of crystals upon exposure to alcohol atmosphere has been observed.

An ultrasonic method to peptize soybean proteins from defatted, autoclaved and alcohol-washed flakes and commercial concentrates and isolates was studied. Extraction conditions were optimized by examining factors including sonic power, meal-to-water ratio, salt concentration, pH and sonic time. The present study reaffirmed the fact that sonication can disperse 80% of total proteins from autocal...

A simple procedure for coating the interior surface of Beckman Ultra-Clear centrifuge tubes with polyvinyl alcohol is described. The coated tubes are wettable and allow salt solutions to gravity-feed down their sides. This modification of the tubes permits the performance of previously developed density gradient and uniform density ultracentrifugation procedures for lipoprotein fractionation.

Well ordered two-dimensional sheets of intact 70 S ribosomes from Bacillus stearothermophilus have been obtained in vitro using salt-alcohol mixtures. These sheets consist of relatively small unit cells with dimensions of 200 +/- 20 A and 400 +/- 30 A. Diffraction patterns of electron micrographs of these sheets stained with uranyl acetate contain features to 42 A resolution.

Certain (Z)-1,5-syn-diols 2 may be converted into 2,6-trans-5,6-dihydropyrans by using phosphonium salt 4 or phosphorane 5 as dehydrating agents. A more general four step procedure converts the (Z)-1,5-syn-endiols into enantiomeric dihydropyrans ent-3 via regioselective silylation of the allylic alcohol unit followed by mesylate formation and base-promoted nucleophilic displacement.

In the preceding papers (1, 2) the preparation and properties of sulfonium salts of methionine were described. The ease of formation of the methylsulfonium salt and the solubility properties of its phosphotungstate suggest utilization for the characterization of methionine in amino acid mixtures, since the phosphotungstates of other a-amino acids are readily soluble in cold aqueous alcohol whil...
