(MRC) Lecture: Biological Energy<br />
Conversion and its Toxic<br />
Consequences<br />
Lecturer: Nobel Laureate Sir John E. Walker, MRC<br />
Dunn Human Nutrition Unit, Cambridge, UK<br />
Energy in foodstuffs is released by respiration<br />
(controlled burning), consuming in the process most<br />
<strong>of</strong> the oxygen that we have breathed in. Of the 1000<br />
or so proteins that are involved, about 100 <strong>of</strong> them are organized into the<br />
respiratory enzyme complexes in mitochondria that function as molecular<br />
machines to convert the redox energy derived from food-stuffs into<br />
adenosine triphosphate (ATP), the energy currency <strong>of</strong> biology. The final<br />
synthetic step is achieved by a remarkable molecular machine that has a<br />
mechanical rotary action. An important toxic by-produce <strong>of</strong> energy conversion<br />
is the production <strong>of</strong> ROS reactive oxygen species (ROS). ROS are<br />
generated during the process <strong>of</strong> electron transfer, but where and how they<br />
are generated remains controversial. The ROS can react with nucleic acids,<br />
proteins and phospholipids causing damage to biological processes that<br />
may lead to diseases and contribute to ageing. Hence, there is a need to<br />
develop drugs to prevent the toxic effects <strong>of</strong> ROS. All <strong>of</strong> these issues will<br />
be discussed in the lecture.<br />

Exhibitor Hosted Session: Automated<br />
In Vivo Sampling with Culex<br />
Presented by: BASi (Bioanalytical Systems, Inc.)<br />
Culex is a modular system for programmed blood and bile sampling,<br />
microdialysis, infusions and physiological measurements. This presentation<br />
will outline the basics <strong>of</strong> automated sampling and how the Culex, a unique<br />
instrument, gets the job done 24/7, using freely-moving animals. You will<br />
learn the differences between manual and automatic sampling and dosing,<br />
and how multiple data streams from a single animal can be obtained at one<br />
time.<br />
Exhibitor Hosted Session: Multiplex Gene<br />
Expression for <strong>Toxicology</strong> Screening <strong>of</strong> Target<br />
Compounds<br />
Presented by: Beckman Coulter, Inc.<br />
Detection <strong>of</strong> cellular response in toxicological studies requires a comprehensive<br />
detection platform that can analyze multiple relevant pathways in a<br />
cost-effective manner. Multiplex gene expression can be employed to look<br />
at various metabolic, cell signaling, or user defined pathways simultaneously.<br />
The Beckman Coulter GeXP Genetic Analysis platform delivers high<br />
throughput gene expression using a simplified chemistry to allow same day<br />
sample to answers.<br />

Children are exposed to tobacco smoke. In a study <strong>of</strong> 5, 400 U.S. school<br />
aged children, 85% had measurable cotinine levels in their blood. Whether<br />
it is prenatal exposure to mainstream smoke or postnatal exposures to sidestream<br />
smoke, childhood exposures are most <strong>of</strong>ten involuntary exposures<br />
and can result in adverse health effects. This is not surprising as tobacco<br />
smoke contains a complex mixture <strong>of</strong> compounds with toxic and/or bioactive<br />
effects. Yet the long term outcomes <strong>of</strong> childhood exposures are still<br />
not well understood. The purpose <strong>of</strong> this session is to bring together the<br />
latest research on the effect <strong>of</strong> tobacco smoke on development <strong>of</strong> the neural,<br />
immune and respiratory systems and to highlight potential areas <strong>of</strong> future<br />
research. There is recent concern about the possibility <strong>of</strong> persistent adverse<br />
health effects <strong>of</strong> tobacco smoke exposure that continue into adulthood after<br />
exposures during development in either the pre or postnatal period. Persistent<br />
effects have been described for the lung, the immune system and for<br />
both behavior and neurobiology.<br />
