Bet v 2 Responsibility in Birch-Induced Symptoms

Abstract

We report the case of a patient who first had grass pollinosis associated to food allergy, especially melon, and who developed secondarily early spring pollinosis which could be related to sensitization to the birch profilin. This patient, whose birch pollinosis was confirmed by nasal provocation test, was not sensitized to Bet v 1, the major birch pollen allergen in North Western Europe. We demonstrated by inhibition studies using grass and birch profilins that the clinical birch allergy was induced by the cross reacting profilin present both in birch and grass pollen and also in melon.

Solution of heat removal from nuclear reactors by natural convection

“…They are required for new types of 4th generation nuclear reactors. [1]. Documentation for designs of natural convection and gas-lift systems for conventional nuclear reactors is missing from Czech literature and for the selected type of MSR with flowing fuel-coolant mixture of fluoride salts the methodology is not even elaborated in the English literature.…”
