Molecular Neurosurgery with Targeted Toxins


Book Description

Pioneers and leading researchers explain the theory and techniques of using targeted toxins experimentally. The highly successful use of the 192 IgG-saporin and ME20.4-saporin immunotoxins to lesion the cholinergic basal forebrain in order to model the behavior, anatomy, physiology, and pharmacology of Alzheimer's disease in animals is treated in detail to give a potential user the knowledge to comfortably use the techniques involved. The uses of important new lesioning agents such as anti-DBH-saporin immunotoxin to make remarkably selective lesions of catecholaminergic neurons, hypocretin-saporin that can produce narcoleptic animals, and other saporin conjugates, such as neuropeptide-saporin conjugates for pain research and cholera toxin B chain-saporin to produce a model of CNS demyelination are explained by experts in the field.




Neurotrophin Protocols


Book Description

The past decade has seen an extraordinary growth in research interest in neurotrophic factors, and the study of the neurotrophin family has led this activity. Nevertheless, this area of research has often struggled as a result of techniques that were either inadequate or just emerging from other research fields and disciplines. Neurotrophin Protocols has brought together many leaders in the neurotrophin field who detail their special expertise in a wide variety of techniques. Though most procedures are valid across many diff- ent fields of research, some of those described here have been developed to address particular issues within the neurotrophic factor field. The protocols cover a broad range of biochemical, histological, and biological techniques that are often required by the modern laboratory. However, all have been written with sufficient detail to allow any laboratory to achieve proficiency without need of reference to other texts. Neurotrophin Protocols is divided into four sections dealing with p- tein, RNA, recombinant, and in vivo techniques. Protein techniques have in general been less successfully employed than those dealing with RNA or DNA. However, procedures that achieve localization and quantification of the neurotrophins are now being used more extensively. Their inclusion here should assist further studies at the protein level. Transgenic cell lines and animals are commonplace in the scientific research literature, but their inc- sion in several chapters in this book provide some novel uses that are not readily available elsewhere.




Ribosome-inactivating Proteins


Book Description

This important reference provides up-to-date information on all aspects of ribosome-inactivating proteins (RIPs). Including a list of all known RIPs, their distribution in nature, structure, genetics and chemical and immunological properties, this reference covers mechanisms of action, including the enzymatic activity on various polynucleotide substrates; the interaction with, and entry into cells; the toxicity to animals, including the pathology of poisoning; and the immunomodulatory and allergenic activity. The book further emphasizes the use of immunotoxins and other conjugates in clinical trials for the therapy of cancer and intractable pain.




An Assessment of the SBIR Program at the National Institutes of Health


Book Description

The SBIR program allocates 2.5 percent of 11 federal agencies' extramural R&D budgets to fund R&D projects by small businesses, providing approximately $2 billion annually in competitive awards. At the request of Congress the National Academies conducted a comprehensive study of how the SBIR program has stimulated technological innovation and used small businesses to meet federal research and development needs. Drawing substantially on new data collection, this book examines the SBIR program at the National Institutes of Health and makes recommendations for improvements. Separate reports will assess the SBIR program at DOD, NSF, DOE, and NASA, respectively, along with a comprehensive report on the entire program.




Principles of Molecular Neurosurgery


Book Description

The future of neurosurgery will be characterized by less invasive, molecular technologies that promise to revolutionize the field of neurosurgery and impact the treatment of additional neurological disorders, including neurometabolic diseases, stroke, dementias, affective and psychiatric diseases, movement disorders, epilepsy, and others. This book encompasses developing an understanding of the principles underlying the advent of novel molecular approaches to neurological and neurosurgical diseases. It Identifies key principles that will allow dramatic improvement in the treatment and outcomes of patients suffering from a varity of disorders affecting the central nervous system and spinal axis. This volume gives neurosurgeons an excellent understanding of the development of novel molecular and cellular technologies that will markedly change the way neurosurgery is practiced in the near future. It is also of special interest to neurologists, psychiatrists, physiatrists, spinal orthopaedic surgeons, neurobiologists and gene therapy research scientists.




Modern Neurosurgery


Book Description

Focusing on how increased understanding of brain function affects clinical neuroscience, this incisive text explores the interface between neuroscience and clinical neuroscience advances by examining the hypotheses that drive this evolution. The author reviews the relevant underpinnings of new neurosurgical techniques, treatments, and conceptual ap




Handbook of Neurotoxicity


Book Description

This handbook is a reference source for identifying, characterizing, instructing on use, and describing outcomes of neurotoxin treatments – to understand mechanisms associated with toxin use; to project outcomes of neurotoxin treatments; to gauge neurotoxins as predictors of events leading to neurodegenerative disorders and as aids to rational use of neurotoxins to model disease entities. Neuroprotection is approached in different manners including those 1) afforded by therapeutic agents – clinical and preclinical; or 2) by non-drug means, such as exercise. The amorphous term ‘neurotoxin’ is discussed in terms of the possible eventuality of a neuroprotectant producing an outcome of excess neuronal survival and a behavioral spectrum that might produce a dysfunction – akin to a neurotoxin’s effect. This new edition significantly expands on the information provided in the first edition, providing the latest research in neurotoxicity and highlighting the relationship between specific neurotoxins and the neurodegenerative disorders they can cause. It also includes new sections on the neurotoxicity of heavy metals, fungi, and snake venom. The Handbook of Neurotoxicity is thus an instructive and valuable guide towards understanding the role of neurotoxins/neurotoxicity in the expansive field of Neuroscience, and is an indispensable tool for laboratory investigators, neuroscientists, and clinical researchers.




The Forgotten Ones


Book Description

"Even high-class prostitute is better than this dullness I live in," thought Julian before he left everything behind. Poor, uneducated, low class, the youth had all odds against him but his beauty and determination to get his way were his greatest capital. A simple job for an eccentric and aloof man could prove to be mankind's greatest challenge."




Chimeric Toxins


Book Description

Bacteria and plants produce powerful toxins that can cause a variety of diseases, some of which are lethal for many animal species. The mechanisms of action are common to many of these toxins and represent general pathways for the interaction of a number of biomolecules with target cells, such as binding to specific surface receptors, internalizati




Toxic Plant Proteins


Book Description

Many plants produce enzymes collectively known as ribosome-inactivating proteins (RIPs). RIPs catalyze the removal of an adenine residue from a conserved loop in the large ribosomal RNA. The adenine residue removed by this depurination is crucial for the binding of elongation factors. Ribosomes modified in this way are no longer able to carry out protein synthesis. Most RIPs exist as single polypeptides (Type 1 RIPs) which are largely non-toxic to mammalian cells because they are unable to enter them and thus cannot reach their ribosomal substrate. In some instances, however, the RIP forms part of a heterodimer where its partner polypeptide is a lectin (Type 2 RIPs). These heterodimeric RIPs are able to bind to and enter mammalian cells. Their ability to reach and modify ribosomes in target cells means these proteins are some of the most potently cytotoxic poisons found in nature, and are widely assumed to play a protective role as part of the host plant’s defenses. RIPs are able to further damage target cells by inducing apoptosis. In addition, certain plants produce lectins lacking an RIP component but which are also cytotoxic. This book focuses on the structure/function and some potential applications of these toxic plant proteins.
