In the last ten years there has been a considerable increase of interest on the notion of the minimal cell. With this term we usually mean a cell-like structure containing the minimal and sufficient number of components to be defined as alive, or at least capable of displaying some of the fundamental functions of a living cell. In fact, when we look at extant living cells we realize that thousands of molecules are organized spatially and functionally in order to realize what we call cellular life. This fact elicits the question whether such huge complexity is a necessary condition for life, or a simpler molecular system can also be defined as alive. Obviously, the concept of minimal cell encompasses entire families of cells, from totally synthetic cells, to semi-synthetic ones, to primitive cell models, to simple biomimetic cellular systems. Typically, in the experimental approach to the construction of minimal the main ingredient is the compartment, lipid vesicles (liposomes) are used to host simple and complex molecular transformations, from single or multiple enzymic reactions, to polymerase chain reactions, to gene expression. Today this research is seen as part of the broader scenario of synthetic biology but it is rooted in origins of life studies, because the construction of a minimal cell might provide biophysical insights into the origins of primitive cells, and the emergence of life on earth. The volume provides an overview of physical, biochemical and functional studies on minimal cells, with emphasis to experimental approaches. 15 International experts report on their innovative contributions to the construction of minimal cells.

This book presents an overview of the current state of research on ultrashort electric field pulses of high intensity and their use in biology and medicine. It examines in detail the most recent and exciting advances in how nanosecond and picosecond electric pulse research has grown and expanded into new areas of biology and medicine. Further, the book specifically focuses on electric pulses in the time domain, on intracellular effects as opposed to plasma membrane electroporation, and highlights the biological and medical applications of these unique pulse effects. Since the authors were initial innovators exploring nanosecond and picosecond pulses, their unique perspectives foreshadowed directions the research took, expanding into new areas that they continue to investigate today.

The purpose of these volumes is to provide a reference work for the methods of purifying many of the receptors we know about. This becomes increasingly important as full-length recep- tors are overexpressed in bacteria or in insect cell systems. A major problem for abundantly expressed proteins will be their purification. In addition to purification protocols, many other de- tails can be found concerning an individual receptor that may not be available in standard texts or monographs. No book of this type is available as a compendium of purification procedures. Receptor Purification provides protocols for the purification of a wide variety of receptors. These include receptors that bind: neurotransmitters, polypeptide hormones, steroid hormones, and ligands for related members of the steroid supergene family and others including receptors involved in bacterial motion. The text of this information is substantial so as to require its publica- tion in two volumes. Consequently, a division was made by grouping receptors depending upon the nature of their ligands. Thus, in volume 1 there are contributions on serotonin receptors, adrenergic receptors, the purification of GTP-binding proteins, opioid receptors, neurotensin receptor, luteinizing hormone re- ceptor, human chorionic gonadotropin receptor, follicle stimulat- ing hormone receptor, thyrotropin receptor, prolactin receptor, epidermal growth factor receptor, platelet derived growth factor receptor, colony stimulating factor receptor, insulinlike growth factor receptors, insulin receptor, fibronectin receptor, interferon receptor, and the cholecystokinin receptor.

Drawing especially on insights emerging from studies of the cellular networks formed by fungi, this book describes the fundamental indeterminacy that enables life forms to thrive in and create inconstant circumstances. It explains how indeterminacy arises from counteraction between associative and dissociative processes at the reactive interfaces between living systems and their surroundings. It stresses the relevance of these processes to understanding the dynamic contexts within which living systems of all kinds - including human societies-explore for, use up, conserve and recycle sources of energy.By focusing on dynamic boundaries, the book counterbalances the discretist view that living systems are assembled entirely from building-block-like units - individuals and genes - that can be freely sifted, as opposed to channeled, by natural selection. It also shows how the versatility that enables life forms to proliferate in rich environments, whilst minimizing losses in restrictive environments, depends on capacities for error and co-operation within a fluid, non-hierarchical power structure. Understanding this point yields a more compassionate, less competitive and less self-centred outlook on life's successes and failures.

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.

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.

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.

At the forefront of life sciences today is the emerging discipline of chembiomolecular science. This new term describes the integration of the frontier fields of chemical biology, chemistry, and pharmacology. Chembiomolecular science aims to elucidate new biological mechanisms as potential drug targets and enhance the creation of new drug therapies. This book comprises the proceedings of the Uehara Memorial Foundation Symposium 2011, which focused on the most recent advances in chembiomolecular science made by leading experts in the field. The book is divided into three main topics. The first is the chemical approach to understanding complex biological systems on a molecular level using chemical compounds as a probe. The second describes the biological approach used to develop new lead drug compounds. The third focuses on the biological system that serves as the potential drug target, the beginning step in the process of developing new drugs. Replete with the latest research, the book will draw the attention of all scientists interested in the synergies between chemistry and biology to elucidate life on a molecular level and to promote drug discovery. Ultimately, the book helps promote the understanding of biological functions at the molecular level and create new pharmaceuticals that can contribute to improving human health.

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 .
