Landes Bioscience produces books in six Intelligence Unit se
ries: Medical, Molecular Biology, Neuroscience, Tissue Engineering,
Biotechnology and Environmental. The authors of our books are
acknowledged leaders in their fields. Topics are unique; almost
without exception, no similar books exist on these topics.
Our goal is to publish books in important and rapidly
changing areas of bioscience for sophisticated researchers and
clinicians. To achieve this goal, we have accelerated our
publishing program to conform to the fast pace at which
information grows in bioscience. Most of our books are
published within 90 to 120 days of receipt of the manuscript.
We would like to thank our readers for their continuing interest
and welcome any comments or suggestions they may have for
future books.

PREFACE
O
xidative stress refers to the cytotoxic consequences of reactive oxy
gen species (ROS) which are generated as by-products of normal or
aberrant metabolic processes that utilize molecular oxygen, or changes
in protection systems. Thus, generation of ROS is a part of normal life
and their interaction with host defense systems appears to exert a sig
nificant influence on the normal and abnormal functioning of the cen
tral nervous system. Oxidative stress could also be a secondary conse
quence of defects in energy metabolism involving mitochondria. A
subbtle shift toward the prooxidant status that occurs in brain aging
could contribute to the pathogenesis and neuropathology of
neurodegenerative disorders exemplified by Alzheimer's disease,
Parkinson's disease and amyotrophic lateral sclerosis. The attractive fea
ture of the oxidative stress hypothesis is that it can account for cumula
tive damage associated with the delayed onset and the progressive na
ture of these conditions. Oxidative damage may constitute a common
pathogenic link between these seemingly diverse neurodegenerative dis
orders.
This book examines current knowledge and recent advances of
fundamental processes involved in neuronal death, particularly oxida
tive stress as a causal, or at least an ancillary, factor in neuronal death.
This book also presents an up-to-date account of the current state of
knowledge about of oxidative stress in neuronal apoptosis and its role in
the neuropathogenesis of age-related neurodegenerative diseases. The
first chapters are devoted to the biology of oxidative stress, biochemical
consequences of damaging free radical reactions in the brain, and their
participation in neurodegenerative processes. Another part of the book
will describe the role of ROS in activation of transcription factors and
its oxidative influence on gene expression, with links to alterations in
cell signalling processes and to neuronal death. Some chapters will ad
dress recent progress in understanding the relationships between its oxi
dative stress, excitotoxicity, mitochondria in neuronal apoptosis and the
potential role for apoptosis in neurodegeneration. The central role of
oxidative stress in the major age-related neurodegenerative disorders is
critically reviewed and potential prevention and therapy by antioxidants
is examined.
