Neurocutaneous Disorders : Phakomatoses and Hamartoneoplastic Syndromes

Neurocutaneous diseases are a wide group of conditions that affect the nervous system but appear as lesions of the skin. Some of the more common entities have variable forms of expression that can confuse the diagnosis; for the rare conditions it is difficult to find descriptions in the literature. Recent insights into their cellular, biochemical and molecular genetic bases have shown the essential need for a new nosology and updated genotype-phenotype correlations. The book provides an authoritative source of knowledge about these difficult problems and bridges the gap between clinical recognition and the new molecular medicine. The editors, distinguished clinicians and geneticists, assembled an internationally renowned group of collaborators, many of them the experts who first described a particular disorder or established its present accepted definition.

Neuroactive Steroids in Brain Function, Behavior and Neuropsychiatric Disorders : Novel Strategies for Research and Treatment

Over the past few decades the involvement of neurosteroids in brain function and mental health has attracted much interest, not only from a neuroscience perspective, but also from clinical and therapeutic aspects. In recent years, much of the research has focused on the multifunctional position of neurosteroids in the nervous system. The areas that have been explored, in particular, are the cellular and molecular mechanisms involved in the activity of neurosteroids in the brain, the role of neurosteroids in brain development, neurodegeneration and neuroplasticity, and their pharmacological properties. The large increase in the number of publications highlights this amplified interest in neurosteroids. Over the last 7 years at least 400 papers have been published describing the putative role of neurosteroids in the modulation of basic brain function and in the etiology and treatment of psychiatric and neurological disorders.

Neoproterozoic Geobiology and Paleobiology

The Neoproterozoic Era (1000-542 million years ago) is a geological period of dramatic climatic change and important evolutionary innovations. Repeated glaciations of unusual magnitude occurred throughout this tumultuous interval, and various eukaryotic clades independently achieved multicellularity, becoming more complex, abundant, and diverse at its termination. Animals made their first debut in the Neoproterozoic too. The intricate interaction among these geological and biological events is a centrepiece of Earth system history, and has been the focus of geobiological investigations in recent decades. The purpose of this volume is to present a sample of views and visions among some of the growing numbers of Neoproterozoic workers. The contributions represent a cross section of recent insights into the field of Neoproterozoic geobiology.

Neonatal Immunity

New advances in cellular immunology, molecular biology, recombinant DNA and proteins, and the function of cytokines and chemokines have revolutionized the study of neonatal immune responsiveness. In Neonatal Immunity, Constantin Bona, MD, critically reviews the classic, as well as most recent-and quite seminal-findings concerning the phenotypic and molecular characteristics of both fetal and neonatal B and T cells, the cells that mediate antibody and cellular immune responses in newborns and infants. Dr. Bona shows how the antibody response of neonates is modulated by maternal antibodies and how, in certain cases, this can cause transient or life-threatening neonatal autoimmune disease. He also describes the characteristics of neonatal tolerance induced by foreign allo- and self-antigens, which are the basis for understanding impaired infant immune response and which provide a rationale for the development of efficient neonatal vaccines. By making clear the characteristics and differences between the immune system and the immune responses of both newborns and infants, compared to those of adults, Dr. Bona offers insights and challenging hypotheses that promise to help overcome the poor responses of neonates to various antigens. Authoritative and forward-looking, Neonatal Immunity critically reviews what we know of the neonatal immune response today, and how this is dramatically opening new therapeutic horizons in such areas as infant vaccination, stem cells, gene therapy, and transplantation.

Natural anti-aging skin care

Ageing is a natural phenomenon which is a fold, ridge and crease in the skin that occurs due to loss of body mass, poor hydration, disintegration of dermis and epidermis junction. The Skin ageing process involves many changes that occur due to the combination of both endogenous factors and exogenous factors. The ageing of the skin occurs due to various mechanisms like glycation, free radical, cell cycle, and cellular and molecular mechanism of skin ageing. In this review article, we have discussed the treatment, worldwide newer therapies and marketed formulation that are currently available for the reduction of skin ageing.

Nanoscale Assembly : Chemical Techniques

Recent advances have pushed the limits of lithography firmly into the sub-100 nm domain, with smallest feature sizes around 10 nm. However, compared to living organisms, devices fabricated using nanolithography are not nearly as complex, as they are essentially 2D and contain only a limited number of chemical elements. For centuries, Nature has been a major inspiration for science. First of all to learn how Life functions at cellular level, but increasingly, as a blueprint for designing non-natural devices where the building blocks and their assembly are inspired by biological examples. The key tool in translating these examples into the domain of engineering, has been self-assembly or self-organization. This book gathers a spectrum researchers who have not only furthered our knowledge of self-assembly using small molecules, polymers and colloidal particles as building blocks, but who have also shown it to be a practical tool in the assembly of an astonishing variety of devices, ranging from molecular electronics to biosensors.

Molecular Parameters Indicating Adaptation to Mechanical Stress in Fibrous Connective Tissue

The present study pursues the hypothesis that local compressive force and the occurrence of cartilage-specific transformation processes within tendons and ligaments are directly correlated. In selected anatomical samples of human origin the distribution pattern of certain components of the extracellular matrix is assessed. Investigations are carried out at the extensor tendons of toes and fingers, at the transverse ligament of the atlas, at the transverse ligament of the acetabulum, and at the tendon of the superior oblique muscle and its trochlea. The molecular components of the extracellular matrix are detected with standardized immunohistochemical methods. The results show that certain molecules only occur due to compressive stress, others due to tensile stress. The molecular spectrum of the extracellular matrix allows qualifying conclusions to the mechanical situation of a given part of the tissue. The spatial expansion of the fibrocartilaginous adaptation zones in tendons and ligaments roughly corresponds with the zones subjected to compressive force; tensile stress alone does not result in a production of fibrocartilage.

Molecular Mechanisms of Parasite Invasion

All of the parasitic organisms highlighted in this new book represent medically important human pathogens that contribute significantly to the global burden of disease. As such there is intense interest in understanding the molecular basis of infection by these pathogens—not only with regard to their clinical relevance but also the fascinating biology they reveal. For most of the parasites discussed here the ability to penetrate biological barriers and/or to establish intracellular residence is critical to survival of the pathogen in the mammalian hosts. For other parasites, a tissue invasive phenotype is a key virulence determinant. In the ensuing 18 chapters, select members of this diverse set of protozoan parasites, as well as some examples of the extremely reduced fungal parasites classified as Microsporidia, are discussed within the context of the fascinating molecular strategies employed by these organisms to migrate across biological barriers and to establish residence within target host cells.
