In 1983, I told Richard Manning about Gale and Shapley’s beautiful 1962 paper on matching. He asked whether in the Gale-Shapley it was in the interest of all participants to tell the truth. We rather quickly showed that in general it is not in the interest of the recipients of offers to be truthful. In fact we were able to show that no mechanism can guarantee efficient assignments and be cheatp...

INTRODUCTION A clinical trial is a research study that prospectively assigns health-related interventions to people (or groups) typically using randomisation to evaluate the effects on health outcomes. Welldesigned, suitably powered, randomised, trials provide the most reliable evidence about the effectiveness (or not) ...

Oxidative stress is highly associated with the development of cardiovascular diseases and cancer and has drawn great attention. Natural products suggest a potential role in prevention of these disorders. The aim of this study was to investigate the antioxidant and anti-cancer properties of Chinese bayberry leaves (Myrica rubra Sieb. et Zucc.) flavonoids (BLF) comprehensively through the combina...

Peatlands in Croatia are rare, small in size and isolated habitats. Due to the abandonment of traditional land-management practices, and particularly to the progressive vegetation succession, they are critically endangered. Caddisfl y faunistics and ecology of peatlands in Croatia have never been studied. A total of seven caddisfl y taxa were collected in this study at three diff erent peatland...

We used airborne imaging spectroscopy and photon transport modeling to determine how biological invasion altered the chemistry of forest canopies across a Hawaiian montane rain forest landscape. The nitrogen-fixing tree Myrica faya doubled canopy nitrogen concentrations and water content as it replaced native forest, whereas the understory herb Hedychium gardnerianum reduced nitrogen concentrat...

Cryphonectria havanensis is a fungus associated with Eucalyptus species in Cuba and Florida (U.S.A.). Until recently, there have been no living cultures of C. havanensis and it has thus not been possible to assess its taxonomic status. Isolates thought to represent this fungus have, however, emerged from surveys of Eucalyptus in Mexico and Hawaii (U.S.A.). Results of this study showed that thes...

Potent inhibitory activity of the leaves of Myrica rubra against both chemical and enzymatic (tyrosinase and lipoxygenase) oxidation was found in our project to develop utility of unused and rarely used plant resources in the local area. A constituent analysis of the most active ethyl acetate-soluble part of a methanol extract of the leaves clarified the structures of eight major compounds. The...

the marine environment represents approximately half of the global biodiversity and could provide unlimited biological resources for the production of therapeutic drugs. marine seaweeds comprise few thousands of species representing a considerable part of the littoral biomass. extracts of the cystoseira indica and cystoseira merica were subjected to phytochemical and cytotoxicity evaluation. th...
