The past decade has witnessed a revolution in the attempts of scientists to under stand the molecular basis of dementia. Although dementia, as defined by global cogni tive decline involving gradual loss of memory, reasoning, judgment, and orientation, presents most commonly in the form of Alzheimer's disease (AD), an assortment of other less common disorders, such as prion and Pick's disease, can also lead to symp toms that are similar to those observed in patients with AD. The primary goal of Molecular Mechanisms of Dementia is to address the various mechanisms and multi faceted approaches currently being employed to more clearly delineate the etiological and pathogenic events responsible for the onset of dementia. Perhaps the greatest boon to obtaining a clearer understanding of the causes of AD has come from genetic and molecular biological studies carried out over the past decade. At the genetic level, it has become increasingly clear that AD is a heteroge neous disorder that can be broadly classified into two categories. "Late onset" (>60 yr) cases, which account for the vast majority of AD, genetically involve "susceptibility" genes representing risk factors for the disease (e. g. , inheritance of the 84 allele of the Apolipoprotein E gene). In many cases, the susceptibility gene can act as a "modifier" that modulates the pathogenic cascade occurring subsequent to a separate etiological event "initiating" or "causing" the disorder.

Oxidation-reduction (i.e. redox) processes at the plasma membrane of any cell have been attracting more and more attention, both in basic and in applied research, since the first workshop dealing with the plasma membrane oxidoreductases was organized in Cordoba, Spain, in 1988. This evolution is evident considering the numerous cell functions performed by plasma membrane redox systems not only in healthy cells but also in cells that escaped from the normal metabolic control (e.g. cancer cells) and cells under attack by pathogens. Plasma membrane redox processes have now been demonstrated to play an essential role in growth control and defense mechanisms of these cells. The great importance of the plasma membrane redox systems originates in the fact that they are located in the membrane which is essentially the site of communication between the living cell and its environment. We may say that the plasma membrane can be considered as the "sensory part" of the cell. No chemical substance can enter the cell interior without interaction with the plasma membrane.

This book discusses the role of oxidative stress in the reproductive system. The book reviews endogenous sources, methods of determining its levels in body fluid/tissues, the physiological roles of ROS, as well as its negative effects on the human reproductive processes. Also discussed are multiple extrinsic factors that could induce oxidative stress in the reproductive system. This volume covers various clinical pathologies related to the reproductive system that arise from or produce oxidative stress, both in the male and female. The use of antioxidants as a therapeutic measure to keep ROS levels in check are highlighted, describing the outcome of various clinical studies involving antioxidant supplementation in infertile patients. Infertility is a global disease that affects 15-25% of all couples, and oxidative stress arising from a multitude of sources has been implicated as one of the major contributing factors to the decline in human fertility. As such, this book provides an up-to-date review on the significance of ROS in human reproduction.

* Several in vivo assays are currently used in the study of angiogenesis and antiangiogenesis * The chick embryo chorioallantoic membrane is one of the most common and versatile assay to study angiogenesis and antiangiogenesis in vivo * Angiogenesis plays a critical role in tumor progression and metastasis * Antiangiogenesis is one of most promising approach to the treatment of cancer and metastasis The chick embryo chorioallantoic membrane (CAM) is an extraembryonic membrane which serves as a gas exchange surface and its function is supported by a dense capillary network. Because of its extensive vascularization and easy accessibility, the CAM has been broadly used to study the morpho-functional aspects of the angiogenesis process in vivo and to investigate the efficacy and mechanisms of action of pro-angiogenic and anti-angiogenic natural and synthetic molecules. The CAM is a suitable site for transplanting tissues, which can survive and develop in the CAM by peripheral anastomoses between graft and original CAM vasculature or by new angiogenic vessels grown from the CAM that invade the graft. While the formation of peripheral anastomoses between host and pre-existing donor vessels is the main, and the most common, mechanism involved in the revascularization of embryonic grafts, the growth of CAM-derived vessels into the graft is only stimulated in tumor grafts. The CAM has long been a favored system for the study of tumor angiogenesis and metastasis, because at this stage the chick immunocompetence system is not fully developed and the conditions for rejection have not been established. Tumors remain avascular for 72 h, after which they are penetrated by new blood vessels and begin a phase of rapid growth. Also, delivery of tumor cells onto the CAM allows the fine study of the effects of tumor derived angiogenic growth factors on blood vessel structure and functionality. The CAM may also used to verify the ability to inhibit th

A major mechanism by which cells regulate protein function is to place phosphate groups on serine and threonine residues. Though the steady-state level of protein phosphorylation depends on the relative activities of both kinases and phosphatases, a much greater effort has previously gone into the study of the former that the latter . Today, however, there is an increasing appreciation for the role that protein phosphatases play in the dynamic p- cess of protein phosphorylation . To date, there are four major types of protein serine/threonine phosphatase catalytic subunits, designated protein phosphatase type 1, 2A, 2B, and 2C . Each has been identified by the techniques of protein chemistry and enzymology and can be distinguished from one another by their preference for specific substrates as well as their sensitivity to certain acti- tors and inhibitors . Protein Phosphatase Protocols has been assembled in response to the growing interest these enzymes are receiving . The goal of this compilation is to provide a "how-to" experimental guide to aid newcomers as well as s- soned veterans in their research endeavors, thus further contributing towards our ever increasing knowledge of serine/threonine phosphatases . What you have before you contains contributions by many of the current and emerging leaders in the field . To highlight just a few, these chapters c- tain step-by-step information on how to isolate novel phosphatases and re- latory subunits, assay for activity, and generate immunological reagents for both biochemical and biological characterization of these enzymes .

Since the epochal discovery of the radical and highly toxic gas nitric oxide (NO) as a signaling molecule, two other no less toxic gases - carbon monoxide (CO) and hydrogen sulfide (H2S) - have been found to also be involved in a plethora of physiological and pathophysiological functions. The gases termed gasotransmitters play an increasingly important role in understanding how signalling into and between cells is modulated and fine-tuned. The advent of gasotransmitters has profoundly changed our way of thinking about biosynthesis, liberation, storage and action mechanisms in cellular signaling. In recent years an impressive amount of new data, distributed throughout the existing literature, has been generated. For this book the editors have recruited distinguished colleagues in the field to summarize and review important biological, pharmacological and medical functions and their implications, as well as methods for the detection of gasotransmitters.

Death receptors play a central role in directing apoptosis in mammalian cells. This process of active cell death is important for a number of biological processes, e.g. for the regulation of the immune system. Death receptors are cell surface receptors that transmit apoptotic signals initiated by corresponding death ligands. Many complex signaling pathways are activated and apoptosis is the final result of a complex biochemical cascade of events.

Besides their role in the induction of cell death, evidence now exists that death receptors are able to activate several non-apoptotic signaling pathways which, depending on cellular context, may lead to apoptosis resistance, secretion of pro-inflammatory proteins, proliferation and invasive growth of cancer cells.

This book looks at the molecular basis of death receptor signaling and the role of death receptors in cancer development.

During the last decade, modern technologies have made a revolutionary change in developmental biology. The molecular and cellular processes in live embryos can now be visualized thanks to technologies using fluorescent proteins. The whole genome information of a wide range of animal species has now become available, confirming the common principles that operate in every species. These and other advances in our understanding of the developmental processes during embryogenesis and tissue regeneration have put forward new principles. Those new principles will also be important in the stem cell biology, branched from developmental biology, in order to generate a particular tissue by manipulating stem cells. This book is planned to introduce these new principles to readers who are working in developmental biology and/or stem cell biology fields, with an emphasis on genetic and cellular processes.

Deficiencies in sperm function are usually the result of spermatogenic defects. Spermatogenesis is a biologically complex and essential process during which spermatogonia undergo meiotic recombination, reduction of the genome to a haploid state, and extensive cellular modifications that result in a motile cell capable of traversing the female reproductive tract, withstanding various potential assaults to viability, and finally successfully fertilizing a mature oocyte to give rise to an embryo. Defects in any step of spermatogenesis or spermatogenesis can lead to male infertility, a disease that affects approximately 5-7% of the population."Spermiogenesis and Spermatogenesis: Methods and Protocols"details protocols used in the study of spermatogenesis, clinical analytical protocols, and basic techniques used in clinical andrology laboratories, such as obtaining accurate results for a sperm count, and advanced procedures, such as genome-wide genetic study tools and evaluation of nuclear proteins.Written in the successful"Methods in Molecular Biology "series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls.

Authoritative and easily accessible, "Spermiogenesis and Spermatogenesis: Methods and Protocols"isunique in its breadth, and will be a useful reference for clinicians and researchers alike."

Research over the years has demonstrated that free radicals mediated oxidative stress lies at the helm of almost all patho-physiological phenomena. These findings emphasize on the need to understand the underlying molecular mechanism(s) and their critical role in the pathogenesis. This book aims to focus on these areas to provide readers a comprehensive outlook about the major redox sensitive pathways and networks involved in various disease conditions. In the first chapter of the book, basic information about the oxidative stress, its generation, its biomarkers and its role in body are discussed. In the next three chapters, the role of oxidative stress in various pathologies ranging from neurological disorders, to cardiovascular diseases, cancers, metabolic diseases and ageing have been described. Chapter 5 cumulatively describes the most important molecular signaling pathways that are affected by reactive oxygen species (ROS). These are the mechanisms which are common denominators in various pathological states. In the next part of the book, various antioxidant strategies to target and mitigate ROS have been discussed with details on the mechanisms. Selenium, being the research focus and interest of the authors for years, the role of selenium as an antioxidant as part of selenoproteins has been included in the book. Finally, the book culminates with authors' perspective on the future of the redox biology field. Throughout the book, efforts have been made to use simplified language and suitable figures for ease to understand the contents. Although the authors have tried to touch on all the different aspects of oxidative stress in detail, the fact that it is a continuously growing field with updates coming every day, there might be some areas which might not be described in depth. This book is designed for students, young scientists to get acquainted with the redox biology. Overall, this book is a reference to understand the redox regulation of cellular signaling pathways involved in pathogenesis.
