Cholesterol Transporters of the START Domain Protein Family in Health and Disease: START Proteins - Structure and Function

by Barbara J. Clark Douglas M. Stocco

Non-vesicular intracellular cholesterol transport is an important mechanism for maintaining membrane cholesterol homeostasis. Recent reports of studies directed at soluble cholesterol transport proteins indicate that aberrant expression of the START proteins may contribute to disease states associated with disorders in cholesterol homeostasis. This is an exciting new direction in the field and the purpose of this book will be to highlight the current research directed at potential roles for the START family in diabetes, cancer and atherogenesis. This book also provides a personal and historical perspective of the discovery-to-publication journey that the authors had for their particular START domain family member. The goal will be to provide perspectives to graduate students, post-doctoral fellows and endocrinology fellows on the research discovery process.

Cholesterol and Beyond: The Research on Diet and Coronary Heart Disease 1900-2000

by A. Stewart Truswell

"Only once in a great while does a book come along that really does the job in addressing a major medical issue. When this happens, all can be joyful... Readers will find ALL their favorite dietary puzzlements dealt with... With consummate scholarship, clarity and brevity, Truswell sifts out the chaff and identifies the critical questions, the responsible investigators, and the key studies." So says Emeritus Professor Henry Blackburn from the University of Minnesota in the foreword to this remarkable concise book on the history of research on diet and heart disease. This was a theme of scientific, medical and public interest in the 20th Century, a century marked by the rise and fall of coronary heart disease as the major cause of death in the first world, followed by the rise of this cause of death in the developing world. There is obviously much to learn, and this book is an excellent starting point, tracing dietary factors and their role in heart disease one by one: fats, sugar, salt, alcohol, coffee, trans-fats, etc. Without an understanding of the role of diet and the changes that have been seen in the North American and NW European diet, the story of the decline in the heart disease death rate may have been very different.

Cholesterol and PI: From Coexistence to Crosstalk (Advances in Experimental Medicine and Biology #1422)

by Avia Rosenhouse-Dantsker

Cholesterol is an essential component of the plasma membrane. Phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2), although a minor phospholipid, is the most abundant membrane phosphoinositide. Both lipids play key roles in a variety of cellular functions including as signalling molecules and major regulators of protein function. Studies on these important lipids have traditionally focused on the effect of each lipid individually. Accumulating evidence indicates, however, that these lipids may cross-regulate each other’s levels. Furthermore, it is becoming evident that cholesterol and PI(4,5)P2 can act together to modulate protein function and biological processes. This book provides an overview of cellular functions and molecular mechanisms in which cholesterol and PI(4,5)P2 functions extend from parallel existence to crosstalk. It includes four sections. The first section introduces the reader to cholesterol and PI(4,5)P2. The second section demonstrates the mutual influence of these two critical lipids on their levels. The third section, divided into two parts, describes the co-modulation of protein function by cholesterol and PI(4,5)P2. The first part focuses on ion channels and the second - on lipid transfer proteins. The fourth section highlights other cellular processes at the intersection of cholesterol and PI(4,5)P2 involvement. Collectively, the book portrays the emerging relationship between cholesterol and PI(4,5)P2 in a broad array of biological systems and processes. The book will be of interest to a wide audience of research scientists with an interest in the biophysical properties of lipids and the physiological consequences of their presence in biological systems, as well as graduate students, postdoctoral trainees, basic and clinical researchers, and pharmaceutical scientists. Specifically, the content will be relevant to researchers in the fields of biochemistry, molecular biophysics, pharmacology, neurobiology, cardiovascular biology, among others.Provides a comprehensive overview of the current knowledge of the interplay between cholesterol and PI(4,5) P2Provides an overview of the emerging relationship between cholesterol and PI(4,5)P2 in biological systems and processesDiscusses cellular processes and molecular mechanisms where lipid functions extend from parallel existence to crosstalk

Choosing Down Syndrome: Ethics and New Prenatal Testing Technologies (Basic Bioethics)

by Chris Kaposy

An argument that more people should have children with Down syndrome, written from a pro-choice, disability-positive perspective.The rate at which parents choose to terminate a pregnancy when prenatal tests indicate that the fetus has Down syndrome is between 60 and 90 percent. In Choosing Down Syndrome, Chris Kaposy offers a carefully reasoned ethical argument in favor of choosing to have such a child. Arguing from a pro-choice, disability-positive perspective, Kaposy makes the case that there is a common social bias against cognitive disability that influences decisions about prenatal testing and terminating pregnancies, and that more people should resist this bias by having children with Down syndrome.Drawing on accounts by parents of children with Down syndrome, and arguing for their objectivity, Kaposy finds that these parents see themselves and their families as having benefitted from having a child with Down syndrome. To counter those who might characterize these accounts as based on self-deception or expressing adaptive preference, Kaposy cites supporting evidence, including divorce rates and observational studies showing that families including children with Down syndrome typically function well. Himself the father of a child with Down syndrome, Kaposy argues that cognitive disability associated with Down syndrome does not lead to diminished well-being. He argues further that parental expectations are influenced by neoliberal ideologies that unduly focus on the supposed diminished economic potential of a person with Down syndrome.Kaposy does not advocate restricting access to abortion or prenatal testing for Down syndrome, and he does not argue that it is ethically mandatory in all cases to give birth to a child with Down syndrome. People should be free to make important decisions based on their values. Kaposy's argument shows that it may be consistent with their values to welcome a child with Down syndrome into the family.

Choosing Sexes

by Kristen J. Navara

There is extensive evidence that vertebrates of all classes have the ability to control the sexes of the offspring they produce. Despite dramatic differences in the mechanisms by which different taxa determine the initial sex of offspring, each group has found its own way of adjusting offspring sex ratios in response to social and environmental cues. For example, stress is a well-known modulator of offspring sex in members of all groups studied to date. Food availability, and limitation in particular, is another common cue that stimulates biases in offspring sex ratios in a wide variety of species. Offspring sex can be adjusted at the primary level, which occurs prior to conception, or at the secondary level, during embryonic development. While the mechanistic pathways that ultimately result in sex ratio biases and the developmental time-points sensitive to those mechanisms likely differ among taxa, the key involvement of steroid hormones in the process of sex ratio adjustment appears to be pervasive throughout. This book reviews the systems of sex determination at play in different vertebrate groups, summarizes the evidence that members of all vertebrate taxa can facultatively adjust offspring sex, and discusses when and how these adjustments can take place.

Choosing and Using a Dobsonian Telescope (The Patrick Moore Practical Astronomy Series #1)

by Neil English

In the 1960's, American amateur astronomer, John Dobson, designed a revolutionary kind of astronomical telescope featuring a lightweight large-aperture reflecting system on a simple mounting, using the then-revolutionary material called teflon. The design combines simplicity and portability with large-aperture prowess. Thirty years later Dobsonians remain supreme for visually observing faint deep-sky objects and are one of the best-selling large telescopes in the USA and Europe. This popularity is reflected in the recent increase of companies now heavily marketing Dobsonians, in particular, Meade (the "Lightbridge" range), Orion USA (XT Intelliscope series), and Skywatcher (Skyliner and Flextube models). This book is the ultimate guide to buying and using commercial Dobsonians, both 'Econo' and 'Primo' models, with in-depth accounts for the various models (plus accessories) on the market and descriptions of the many innovations that amateurs have made to optimize their telescopes' performance.

Computerized SCTs, Maksutov-Cassegrains, and most recently Meade's new and acclaimed Ritchey-Chrétiens have come to dominate the market. That means that all amateurs considering the purchase of a new telescope (not only a SCT, and not just beginners) will benefit from this detailed guide. Choosing the right telescope for particular kinds of observation (or even for general work) is far from easy - but Rod Mollise gives invaluable advice and guidance.

Choosing and Using a New CAT: Getting the Most from Your Schmidt Cassegrain or Any Catadioptric Telescope (The Patrick Moore Practical Astronomy Series)

by Rod Mollise

Catadioptric telescopes (CATs) such as the Schmidt Cassegrains remain popular among amateur astronomers for their ability to reveal thousands of beautiful deep-space wonders. Additionally, their computer-assisted capabilities allow them to automatically point to and track celestial objects, making astronomy accessible to more people than ever before. However, selecting the right one and learning how to use it can be difficult for stargazers both old and new. That’s where this book comes in. The first edition, published in 2009, has remained the standard reference for mastering these popular instruments. This revised edition brings the material completely up to date, with several extensively rewritten chapters covering the most recent developments in telescope and camera equipment as well as computer software.Through the author’s 45 years of experience with catadioptric telescopes, readers will learn to decide which catadioptric telescope is right for them, to choose a specific make and model, and finally, to use the telescope in the field. Covered in other chapters are: Solar System and deep-sky observations; astrophotography and computer control of CATs; and troubleshooting and maintaining your equipment.If you dream of owning a telescope or are frustrated by the telescope you already own, this is the book for you!

Choosing and Using a Refracting Telescope (The Patrick Moore Practical Astronomy Series)

by Neil English

Choosing and Using a Refracting Telescope has been written for the many amateur astronomers who already own, or are intending to purchase, a refracting telescope - perhaps to complement their existing arsenal of larger reflecting telescopes - or for the specialist who requires a particular refractor for serious astronomical applications or nature studies. Four hundred year ago, during the winter of 1609, a relatively unknown Italian scientist, Galileo Galilei designed a spyglass with two crude lenses and turned it skyward. Since then, refractors have retained their dominance over all types of reflector in studies of the Moon, planets and double stars because of the precision of their optics and lack of a central obstruction in the optical path, which causes diffraction effects in all commercially-made reflectors. Most mature amateur astronomers got started with a 60mm refractor, or something similar. Thirty years ago, there was little choice available to the hobbyist, but in the last decade long focus crown-flint achromats have moved aside for some exquisitely crafted apochromatic designs offered by leading commercial manufacturers. There has been a huge increase in the popularity of these telescopes in the last few years, led by a significant increase in the number of companies (particularly, William Optics, Orion USA, StellarVue, SkyWatcher and AstroTech) who are now heavily marketing refractors in the amateur astronomical magazines. In Choosing and Using a Refracting Telescope, well-known observer and astronomy writer Neil English celebrates the remarkable history and evolution of the refracting telescope and looks in detail at the instruments, their development and their use. A major feature of this book is the way it compares not only different classes of refractor, but also telescopes of each class that are sold by various commercial manufacturers. The author is perhaps uniquely placed to do this, having used and tested literally hundreds of different refracting telescopes over three decades. Because it includes many diverse subjects such as imaging with consumer-level digital cameras, imaging with webcams, and imaging with astronomical CCD cameras - that are not covered together in equal depth in any other single volume - Choosing and Using a Refracting Telescope could become the 'refractor bible' for amateur astronomers at all levels, especially those who are interested in imaging astronomical objects of every class.
