Recent analyses of hop (Humulus lupulus L.) secondary metabolites confirm a role of hop as a "molecular factory" crop being a rich source for new medicaments. New studies have particularly focused on prenylated flavonoids and to biochemical potential of Xanthohumol as a fascinating cancer-chemopreventive compound acting at all stages of carcinogenesis. The recent finding that Xanthohumol can be converted to the most potent plant phytoestrogen, 8-prenylnaringenin by human intestinal microflora, increases the availability of this compound from natural hop products.The first food supplement made from hop, so-called MenoHop has been released to the market...

Non sustainable development. Ecosystem services.Not peer-reviewed article

Ecosystem services contribute to human welfare much more than economic activities of mankind themselves. Atmospheric gas composition and climate regulation, soil fertility, nutrient cycling, waste treatment, water purification and supply, and a source of genes in organisms  as well as cultural and recreation enjoyment, all represents irreplaceable conditions for the existence of current human societies. At the same time, the large and growing global human population and demands of each human being, clearly induce deterioration of both the composition - even to large-scale extinctions of organisms - and functions of biomes although these are essential...
