The eukaryotic translation machinery must recognize the site on a messenger RNA (mRNA) where decoding should begin and where it should end. The selection of the translation start site is generally given by the ?rst AUG codon encoding the amino acid methionine. D- ing initiation soluble translation initiation factors (eukaryotic translation initiation factors [eIFs] in eukaryotes and prokaryotic translation initiation factors [IFs] in prokaryotes) bind the mRNA, deliver the initiator Met-tRNA, and assemble to form a complete 80S ribosome from the 40S and 60S subunits. By progressing along the mRNA in the 5 -to-3 direction the ribosome decodes the information and translates it into the polypeptide chain. During this process, repeated delivery of amino-acyl tRNA (aa-tRNA) to the ribosome, peptide bond formation, movement of the mRNA, and the growing peptidyl-tRNA is mediated by both soluble elongation factors (eukaryotic translation elongation factors [eEFs] in euka- otes and prokaryotic translation elongation factors [EFs] in prokaryotes) and the activity of the ribosome. The ?nal step in the translation process occurs when one of the three t- mination codons occupies the ribosomal A-site. Translation comes to an end and soluble release factors (eukaryotic translation termination factors [eRFs] in eukaryotes and proka- otic translation termination factors [RFs] in prokaryotes) facilitate hydrolytical release of the polypeptide chain (for recent reviews, see Inge-Vechtomov et al. 2003; Kisselev et al. 2003; Wilson and Nierhaus 2003; Kapp and Lorsch 2004).

"Research into gastrointestinal motility has received renewed interest in part due to recent advances in the techniques for measuring the structure and function of gastrointestinal cells, tissue and organs. The integration of this wealth of data into biophysically based computation models can aid in interpretation of experimental and clinical measurements and the refinement of measurement techniques."

"The contents of this book span multiple scales - from cell, tissue, organ, to whole body and is divided into four broad sections covering: i) gastrointestinal cellular activity and tissue structure; (ii) techniques for measuring, analyzing and visualizing high-resolution extra-cellular recordings; (iii) methods for sensing gastroelectrical activity using non-invasive bio-electro-magnetic fields and for modulating the underlying gastric electrical activity and finally (iv) methods for assessing manometric and videographic motility patterns and the application of these data for predicting the flow and mixing behavior of luminal contents by using computational fluid dynamic techniques. "

"This book aims to provide both an overview of historical and existing research techniques as well as to highlight future directions and challenges for the community as a whole. It will be suitable for clinicians to understand the cellular and biophysical underpinnings of gastric emptying, gastroenterologists, surgeons, bioengineers and all scientists with interests in gastrointestinal motility research."

Bioinformatics as a discipline has come of age, and there are now numerous databases and tools that are widely used by researchers in the biomedical field. However, successful development of future bioinformatics applications will depend on an appropriately formalised representation of domain knowledge.

In the last forty years anthropologists have made major contributions to understanding the heterogeneity of reproductive trends and processes underlying them. Fertility transition, rather than the story of the triumphant spread of Western birth control rationality, reveals a diversity of reproductive means and ends continuing before, during, and after transition. This collection brings together anthropological case studies, placing them in a comparative framework of compositional demography and conjunctural action. The volume addresses major issues of inequality and distribution which shape population and social structures, and in which fertility trends and the formation and size of families are not decided solely or primarily by reproduction.

As cells mature they naturally stop dividing and enter a period called senescence. But cellular senescence can also be induced prematurely by certain oncogenes involved in cancer development. Cellular senescence, a growth-arrest program that limits the lifespan of mammalian cells and prevents unlimited cell proliferation, is attracting considerable interest because of its links to tumor suppression.

Biological rhythms time the ebb and flow of virtually every physiological process, and their mutual coordination guarantees the integrity of the organism over space and time. Aging leads to the disintegration of this coordination, as well as to changes in the amplitude and/or frequency of the underlying rhythms. The results of this are accelerated loss of health during aging, and in experimental model systems curtailed lifespan occurs. This book will examine the machinery that constitutes circadian systems and how they impact physiologic processes. It will also discuss how disturbances of circadian rhythms can lead to complex diseases associated with aging. Much of this treatment will focus on metabolism and genome stability. Importantly, the chapters in this book will encompass work in several different models, in addition to human. The book will conclude with a discussion of modeling approaches to biologic cycles and chronotherapy, for future research and translation.

This volume explores the epigenetic alterations and their association with various human cancers. Considering one of human cancer as an example, individual chapters are focused on defining the role of epigenetic regulators and underlying mechanisms in cancer growth and progression. Epigenetic alteration including DNA methylation, histone modification, nucleosome positioning and non-coding RNAs expression are involved in a complex network of regulating expression of oncogenes and tumor suppressor genes and constitute an important event of the multistep process of carcinogenesis. Recent advances in the understanding of the epigenetic regulation and detailed information of these epigenetic changes in various cancers provide new avenues of advancements in diagnostics, prognostics, and therapies of this highly fatal disease.

In just under three decades, the world has witnessed an enormous rise in obesity with a parallel growth in cardiometabolic disease risk factors characterized by insulin resistance, dyslipidemia, and hypertension, together known as the metabolic syndrome - conditions previously unheard of in children and adolescents. During this time, we have little knowledge of the global and cumulative detrimental health effects of childhood obesity. As obese children age, not only will their health be negatively affected, but infertility and pregnancy complications associated with the metabolic syndrome will affect generations to come. The work force will undoubtedly be affected because of increased sick days and decreased work productivity. Identifying children and adolescents at the earliest stages of chronic disease onset should be the goal of clinical practice, yet there is no clear guidance for defining the risk of metabolic syndrome or appropriate risk-factor thresholds in these groups. If children are identified early in the disease process, lifestyle and clinical interventions can be instituted when they are potentially more effective. Pediatric Metabolic Syndrome: Comprehensive Clinical Review and Related Health Issues approaches the pediatric metabolic syndrome by elucidating its effects on specific organ systems and by considering the problem through understanding the social, psychological and economic consequences of it. The Editors have recruited an invited group of esteemed experts in the field to provide the most timely and informative approaches on how to deal with this health crisis. Through educating our practitioners, our future researchers, our health and community organizations, our legislators and our families and children, we have the best chance at improving the health trajectory of the next generation.

Chapters by prominent experts will stimulate new ideas and set the scene for productive discussion on this topic.

The Multiple Inert Gas Elimination Technique (MIGET) is a complex methodology involving specialized gas chromatography and sophisticated mathematics developed in the early 1970's. Essentially, nobody possesses knowledge of all its elements except for its original developers, and while some practical and theoretical aspects have been published over the years, none have included the level of detail that would be necessary for a potential user to adopt and understand the technique easily. This book is unique in providing a highly detailed, comprehensive technical description of the theory and practice underlying the MIGET to help potential users set up the method and solve problems they may encounter. But it is much more than a reference manual - it is a substantial physiological and mathematical treatise in its own right. It also has a wide applicability - there is extensive discussion of the common biological problem of quantitative inference. The authors took measured whole-lung gas exchange variables, and used mathematical procedures to infer the distribution of ventilation and blood flow from this data. In so doing, they developed novel approaches to answer the question: What are the limits to what can be concluded when inferring the inner workings from the "black box" behavior of a system? The book details the approaches developed, which can be generalized to other similar distributed functions within tissues and organs. They involve engineering approaches such as linear and quadratic programming, and uniquely use mathematical tools with biological constraints to obtain as much information as possible about a "black box" system. Lastly, the book summarizes the hundreds of research papers published by a number of groups over the decades in a way never before attempted in order to marshal the world's literature on the topic and to provide in one place the wealth of important discoveries, both physiological a nd clinical, enabled by the technique.

Human beings normally have a total of 46 chromosomes, with each chromosome present twice, apart from the X and Y chromosomes in males. Some three million people worldwide, however, have 47 chromosomes: they have a small supernumerary marker chromosome (sSMC) in addition to the 46 normal ones. This sSMC can originate from any one of the 24 human chromosomes and can have different shapes. Approximately one third of sSMC carriers show clinical symptoms, while the remaining two thirds manifest no phenotypic effects. This guide represents the first book ever published on this topic. It presents the latest research results on sSMC and current knowledge about the genotype-phenotype correlation. The focus is on genetic diagnostics as well as on prenatal and fertility-related genetic counseling. A unique feature is that research meets practice: numerous patient reports complement the clinical aspects and depict the experiences of families living with a family member with an sSMC.
