Molecular Markers of Brain Tumor Cells : Implications for Diagnosis, Prognosis and Anti-Neoplastic Biological Therapy

Childhood brain tumors are a diverse group of diseases characterized by the abnormal growth of tissue contained within the skull. Other than leukemia and lymphoma, brain tumors are the most common type of neoplasms that occur in children. The leading cause of death from childhood neoplasms among persons up to 19 years is brain tumors. As such, this book is a review of the most recent molecular biological research concerning brain tumors with references and comparisons to a variety of neoplastic disorders. The book then uses this information to foreshadow the direction that future anti-neoplastic therapies will take. Because of the wide spectrum of the objectives of the book, any individual involved in cancer research will greatly benefit from the work. Histopathologists, neuropathologists, clinical and research oncologists, and medical students will find this book to be an invaluable resource as a reference guide. Patients and their families will also find the book useful as it offers a comprehensive update on new, non-classical therapeutic modality options and contains a detailed description and analysis of brain tumors. Such an endeavor has yet to be undertaken by any other book and may prove to be the most comprehensive book on brain tumors thus far.

Molecular Gels : Materials with Self-Assembled Fibrillar Networks

Molecular gels and fibrillar networks – a comprehensive guide to experiment and theory Molecular Gels: Materials with Self-Assembled Fibrillar Networks provides a comprehensive treatise on gelators, especially low molecular-mass gelators (LMOGs), and the properties of their gels. The structures and modes of formation of the self-assembled fibrillar networks (SAFINs) that immobilize the liquid components of the gels are discussed experimentally and theoretically. The spectroscopic, rheological, and structural features of the different classes of LMOGs are also presented. Many examples of the application of the principal analytical techniques for investigation of molecular gels (including SANS, SAXS, WAXS, UV-vis absorption, fluorescence and CD spectroscopies, scanning electron, transmission electron and optical microscopies, and molecular modeling) are presented didactically and in-depth, as are several of the theories of the stages of aggregation of individual LMOG molecules leading to SAFINs. Several actual and potential applications of molecular gels in disparate fields (from silicate replication of nanostructures to art conservation) are described. Special emphasis is placed on perspectives for future developments.

Molecular evolutionary models in drug discovery

Explores the application of evolutionary molecular models in drug discovery in which secondary metabolites play a fundamental role. Secondary metabolites are not produced in isolation, they are the result of the interaction of genes, metabolism and the environment. The book examines the role of secondary metabolites as leads in drug discovery and on the development of a rational bioprospecting model for new medicines based on the evolution of secondary metabolism. These evolutionary models are part of biological systems and are the most reliable expression of the functioning of living beings.

Molecular Chaperones in Health and Disease

Molecular chaperones are involved in a wide variety of essential cellular processes in living cells. A subset of molecular chaperones have been initially described as heat shock proteins protecting cells from stress damage by keeping cellular proteins in a folding competent state and preventing them from irreversible aggregation. Later it became obvious that molecular chaperones are also expressed constitutively in the cell and are involved in complex processes such as protein synthesis, intracellular protein transport, post-translational modification and secretion of proteins as well as receptor signalling. Hence, it is not surprising that molecular chaperones are implicated in the pathogenesis of many relevant diseases and could be regarded as potential pharmacological targets. Starting with the analysis of the mode of action of chaperones at the molecular, cellular and organismic level, this book will then describe specific aspects where modulation of chaperone action could be of pharmacological and therapeutic interest.

Molecular Biology of the Parathyroid

Caintaining extracellular calcium concentrations within a narrow range is critical for the survival of most vertebrates. PTH, together with vitamin D, responds to hypocalcemia to increase extracellu­ M lar calcium levels, by acting on bone, kidney and intestine. The recent intro­ duction of PTH as a major therapeutic agent in osteoporosis has directed renewed interest in this important hormone and in the physiology of the parathyroid gland. The parathyroid is unique in that low serum calcium stimulates PTH secretion. As hypocalcemia persists, there is also an increase in PTH synthesis. Chronic hypocalcemia leads to hypertrophy and hyper­ plasia of the parathyroid gland together with increased production of the hormone. Phosphate is also a key modulator of PTH secretion, gene expres­ sion and parathyroid cell proliferation. Understanding the biology of the parathyroid as well as the mecha­ nisms of associated diseases has taken great strides in recent years. This book summarizes the molecular mechanisms involved in the function of the para­ thyroid gland. The first chapter reviews the development of the parathyroid gland and the genes involved in this process as identified using genetically manipulated mice. Then the biosynthetic pathway of PTH from gene ex­ pression to its intracellular processing and the sequences in the gene control­ ling its transcription as well as those regulating mRNA processing, stability and translation are described.

Molecular Biology of Metal Homeostasis and Detoxification : From Microbes to Man

One of the challenges faced by every cell as well as by whole organisms is to maintain appropriate concentrations of essential nutrient metals while excluding nonessential toxic metals. Toward that end, all organisms have developed mechanisms for metal homeostasis and detoxification to maintain metal levels within physiological limits. This book brings together current knowledge of the molecular basis of metal homeostasis and detoxification in various eukaryotic model systems, including yeasts, plants, and mammals. It focuses on the cellular systems controlling metal transport, intracellular distribution, and immobilization as well as on systems regulating metal-dependent transcription. In addition to environmental aspects (including phytoremediation), the book treats the pathophysiology of metal deficiency and overload in relation to disease.

Molecular Beams in Physics and Chemistry : From Otto Stern's Pioneering Exploits to Present-Day Feats

This book gives a comprehensive account of both the history and current achievements of molecular beam research. In 1919, Otto Stern launched the revolutionary molecular beam technique. This technique made it possible to send atoms and molecules with well-defined momentum through vacuum and to measure with high accuracy the deflections they underwent when acted upon by transversal forces. These measurements revealed unforeseen quantum properties of nuclei, atoms, and molecules that became the basis for our current understanding of quantum matter. This volume shows that many key areas of modern physics and chemistry owe their beginnings to the seminal molecular beam work of Otto Stern and his school. Written by internationally recognized experts, the contributions in this volume will help experienced researchers and incoming graduate students alike to keep abreast of current developments in molecular beam research as well as to appreciate the history and evolution of this powerful method and the knowledge it reveals.

Molecular Basis of Symbiosis

Symbiotic associations involving prokaryotes occur ubiquitously and are ecologically highly significant. In symbiotic associations, co-evolution of the partner organisms has led to specific mechanisms of signal exchange and reciprocal regulation, and resulted in novel physiological capabilities of the association as compared to those of the individual partners. Symbiosis research has recently entered an exciting era because molecular biology techniques are available for studying partner organisms in association and in a culture-independent manner. It is the goal of this book to contribute towards a broader perspective and an understanding of the function of symbiotic systems. 14 different model systems have been chosen, comprising well known symbioses as well as novel experimental systems which have only recently become amenable to experimental manipulation.

Modulation of host gene expression and innate immunity by viruses

This book is reference on a relatively young area of research in which virology, cellular biology and molecular pathogenesis govern the principles of coinvestigation. Infection of a naïve (non-immune) host with a virus elicits an immediate response which results in a cascade of changes in the host, including an interferon response (innate immunity). The outcome of this interaction is influenced by the genes of the virus as well as the genes of the host. Interestingly, different viruses do it in different ways. Not only is there a plethora of mechanisms used by the invading organisms, but the host has also evolved a great variety of redundant and robust countermeasures. This interplay of host and virus represents one of the most significant frontiers in biology today. A clearer understanding of the mechanisms involved will arm us with better strategies to deal with viruses, including emerging pathogens and potential bioterrorism agents. This book is sure to benefit students, scientists, and physicians working in the areas of virology, immunology, microbiology, and infectious diseases.

Modular Forms

It provides the reader with the basic knowledge of elliptic modular forms necessary to understand the recent developments in number theory. The first part gives the general theory of modular groups, modular forms and Hecke operators, with emphasis on the Hecke-Weil theory of the relation between modular forms and Dirichlet series. The second part is on the unit groups of quaternion algebras, which are seldom dealt with in books. The so-called Eichler-Selberg trace formula of Hecke operators follows next and the explicit computable formula is given. In the last chapter, Eisenstein series with parameter are discussed following the recent work of Shimura: Eisenstein series are likely to play a very important role in the future progress of number theory, and this chapter provides a good introduction to the topic.

Modular Algorithms in Symbolic Summation and Symbolic Integration

Brings together two streams in computer algebra: symbolic integration and summation on the one hand, and fast algorithmics on the other hand. In many algorithmically oriented areas of computer science, the analysis of al gorithms placed into the lime light by DonKnuth’stalkat the 1970ICM –provides a crystal-clear criterion for success. The researcher who designs an algorithm that is faster (asymptotically, in the worst case) than any previous method receives instant gratification : her result will be recognized as valuable. Al as, the downside is that such results come along quite infrequently, despite our best efforts. An alternative evaluation method is to run a new algorithm on examples; this has its obvious problems, but is sometimes the best we can do. George Collins, one of the fathers of computer algebra and a great experimenter,wrote in 1969: “I think this demonstrates again that a simple analysis is often more revealing than a ream of empirical data (although both are important). ” Within computer algebra, some areas have traditionally followed the former methodology, notably some parts of polynomial algebra and linear algebra. Other areas, such as polynomial system solving, have not yet been amenable to this - proach. The usual “input size” parameters of computer science seem inadequate, and although some natural “geometric” parameters have been identified (solution dimension, regularity), not all (potential) major progress can be expressed in this framework. Symbolic integration and summation have been in a similar state.
