INVITATION
Dear Colleagues, Ladies and Gentleman,
it is my great pleasure to invite you to 4rd International Conference
on ROLE OF FORMALDEHYDE IN BIOLOGICAL SYSTEMS- METHYLATION AND
DEMETHYLATION PROCESSES in the Thermal Hotel AQUINCUM in the
beautiful, historical district of Budapest July l to 4, l998. The aim
of the Organizing Committee is to provide you a high level scientific
conference and a pleasent filling time in Budapest. We want to provide
an excellent opportunity for scientific consultation, to strengthen
connections between friends and especially a good atmosphere. As you
know, our special aim is to help a better understanding of the
pathways and functions of formaldehyde in biological systems. We hope
that colleagues from different fields will participate in this unique
meeting demonstrating the general importance of this normal and
indispensable molecule in biological processes. The scientific
programme has been arranged to cover the most up-to-date themes of
formaldehyde research and provide the opportunity for scientists to
hear and discuss new results obtained and problems emerging from this
very interesting and important field of biological and chemical
sciences. I hope to welcome you and your family in one of the most
lovely capitals of Central Europe!
