Metallothionein, a low-molecular-weight protein whose apoprotein, thionein, is induced by exposure to cadmium, copper, mercury and zinc, plays an important role in the transport and storage of heavy metals; it also provides a protective role against the toxic effects of these metals by sequestering and thus reducing the amount of the free metal ions. Interest in the detoxification role of metallothionein in fisheries research and aquatic toxicology has increased because of the increasing contamination of aquatic habitats by heavy metals. Reports of laboratory and field investigations have shown that metallothionein synthesis is induced in fishes during chronic and acute exposures to metals. There is also evidence of the presence in fish of low-molecular-weight inorganic-binding proteins that are different from metallothionein, as well as evidence that cadmium is not sequestered by metallothien in rainbow trout Salmo gairdneri. The sequestering of metal contaminats by metallothionien and sunsequent toxic effects in fish and other animals has been described be the spillover hypothesis, which states that once metallothionein is saturated by metals, excess ions spill over into other cellular compartments and cause pathological lesions. We review the literature on metallothionen in fish, and emphasize the protein role in the detoxification and binding of metal contaminants. |

Tropical viticulture in the world: climatic characteristics and limits Tropical vitiviniculture is expanding rapidly for a variety of reasons (economic, political, health, etc.). Between the tropics, the absence of a cold season allows a continuous growth of the vine, offering the possibility of making several harvests a year. The beginning of each "vegetative cycle" of the vine is controlled by human intervention, which makes it possible to choose the time of year when the climatic conditions are most favorable to the oenological potential of the grape. But this "flexibility" is not systematic.
