Abstract Alzheimer’s disease (AD) is a disorder associated with progressive degeneration of memory and cognitive function. Galantamine licenced treatment for AD but supplies the plant alkaloid that it produced from, galanthamine, are limited. This three-year system study tested potential to combine Narcissus -derived galanthamine production grassland-based ruminant production. Replicate plots p...

Recently several complete cDNAs encoding the Narcissus tazetta lectins (NTL) were cloned. The sequence analyses of the cloned DNAs reveal that there are at least three unidentical positive clones for NTLs. The primary structure of the three NTL clones contains a mature polypeptide consisting of 105 amino acids and a C-terminal peptide extension beyond the C-terminal amino acids Thr-Gly. There a...

The Mediterranean coastline is a dynamic and complex system which owes its complexity to its past and present vicissitudes, e.g. complex tectonic history, climatic fluctuations, and prolonged coexistence with human activities. A plant species that is widespread in this habitat is the sea daffodil, Pancratium maritimum (Amaryllidaceae), which is a perennial clonal geophyte of the coastal sands o...

In her article "The Posthuman Ethos in Cyberpunk Science Fiction" María Goicoechea explores the posthuman tendencies of Anglo-American popular culture as they are manifested in the representations of the cyborgs, clones, and artificial intelligences that populate cyberpunk science fiction. Choosing the figure of the cyborg as the central myth of cyberculture, Goicoechea exposes the underlying t...

A numnber of authors have recommended the use of photometric apparatus for determining leaf area, and at least 1 commercially-manufactured instrument is available. In principle the leaf is placed between a light source and a photocell or battery of photocells: the reduction in photocell output due to the presence of the leaf then gives a measure of leaf area. The transmission of light through t...
