A serine proteinase from roots of Taraxacum officinale Webb S. L. was isolated by affinity chromatography and gel-filtration on Superose 6R using FPLC. The enzyme is a 67-kD glycoprotein containing 54% carbohydrate which we have named taraxalisin. The substrate specificity of taraxalisin toward synthetic peptides and oxidized insulin B-chain is comparable with that of cucumisin from Cucumis mel...

A season-long survey of common weeds was taken near onion and potato fields located within a large vegetable production region in western New York in 2008 and 2009. The objective was to determine the abundance of weed species known as hosts for Iris yellow spot virus (IYSV), a serious pathogen of onion, Potato leafroll virus (PLRV) and Potato virus Y (PVY), which are major pathogens of potato. ...

Diverse mesoporous CuO nanostructures have been prepared by a facile and scaleable wet-chemical method and reduced to mesoporous Cu nanostructures by using the reductant ammonia borane (AB). These mesoporous Cu nanostructures have been applied as a catalyst for hydrogen generation from the methanolysis of AB. The catalytic results show that the reaction rate and the amount of hydrogen evolution...

The phenolic extract of chives flowers (Allium schoenoprasum, Liliaceae), introduced Sage (Salvia pratensis, Lamiaceae), European elderberry (Sambucus nigra, Caprifoliaceae) and common dandelion (Taraxacum officinale, Asteraceae) were characterised by High Performance Liquid Chromatography and incorporated in different concentrations onto atelocollagen thin films. In order to assess the biologi...

specifically. The book is supported by over 200 references and half again as many personal communications. The high-quality scanning electron micrographs of pollen grains are especially appealing. Willow, mimosa, and dandelion pollen have an architecture as intricate and beautiful as the plant superstructure which supports them. The spiny spherical pollen grains of ambrosia (ragweed) make them ...

In this paper, preliminary studies of ten different plant extracts as potential corrosion inhibitors carbon steel were examined. For each extract, the concentration range in which it shows anti-corrosion action was first determined, and then most effective determined for extract. The tests performed a brine solution saturated with CO2 at room temperature. aim study to isolate high effectiveness...
