Third Keele Meeting on Aluminium, 1999
The Bioinorganic Chemistry of Aluminium: from Microbe to Man
22nd - 24th February 1999
Aims of the Meeting
Aluminium is one of only a few elements to have been discussed at all levels of public life. Unfortunately, much of the debate concerning its impact upon biota, including man, has been uninformed and has served only to trivialise this important field of research. The study of aluminium and its activity in biological systems is easily justified. Its ubiquity alone suggests biological function, and yet, none has been found. What is clear is that aluminium is found in all biota and that this occurrence is either the vestige of a metal that has been selected out of biological processes or the result of a burgeoning exposure which is currently an active player in natural selection. It is, perhaps, the latter possibility that courts such red mists of controversy.
Our role as scientists is to look beyond the controversy and to provide the best possible indications of the biological activity of aluminium. All researchers working on aluminium will contribute to this process. The Keele Meetings promote a multidisciplinary approach bringing together all scientists with an interest in the chemistry and biology of aluminium. The term, bioinorganic chemistry, is simply a description of how research from different fields can be brought together and, perhaps, re-interpreted to offer an interdisciplinary explanation of the observed effects of biologically available aluminium. The continued aim of the Keele Meetings on Aluminium is to promote such an approach.
Call for Papers
The Keele Meetings provide a forum for the presentation of new, previously unpublished research relating to the field of Aluminium in Biology. Papers are also invited on the related topics of Silicon Essentiality and Silicification in Biota. Platform presentations should be of 20 minutes duration to allow a further 10 minutes for discussion. Participants presenting posters will be offered a 5 minute slot within a related platform session to 'advertise' their poster. A prize will be presented for Best Poster. All presentations, platform and poster, will be eligible for submission for publication in the Journal of Inorganic Biochemistry. The Keele Issue will be a regular issue of the journal (see for example JIB (1998) Volume 69, Number 3) and all submissions will be subject to peer review. If you are interested in presenting your research please send a 150 word abstract, indicating your preference, platform or poster, to Dr C Exley, Birchall Centre for Inorganic Chemistry and Materials Science, Department of Chemistry, Keele University, Staffordshire, ST5 5BG, UK. The deadline for submission for platform presentations is 31st October 1998 but abstracts for poster presentations will be considered after this date.
