The Cancer Code - A Revolutionary New Understanding of a Medical Mystery (Paperback): Dr. Jason Fung The Cancer Code - A Revolutionary New Understanding of a Medical Mystery (Paperback)
Dr. Jason Fung
R417 Discovery Miles 4 170 Ships in 12 - 17 working days

Our understanding of cancer is slowly undergoing a revolution, allowing for the development of more effective treatments. For the first time ever, the death rate from cancer is showing a steady decline ... but the 'War on Cancer' has hardly been won. In The Cancer Code, Dr Jason Fung offers a revolutionary new understanding of this invasive, often fatal disease - what it is, how it manifests and why it is so challenging to treat. In this rousing narrative, Dr Fung identifies the medical community's many missteps in cancer research - in particular, its focus on genetics, or what he terms the 'seed' of cancer, at the expense of examining the 'soil,' or the conditions under which cancer flourishes. Dr Fung - whose ground-breaking work in the treatment of obesity and diabetes has won him international acclaim - suggests that the primary disease pathway of cancer is caused by the dysregulation of insulin. In fact, obesity and type 2 diabetes significantly increase an individual's risk of cancer. In this accessible read, Dr Fung provides a new paradigm for dealing with cancer, with recommendations for what we can do to create a hostile soil for this dangerous seed. One such strategy is intermittent fasting, which reduces blood glucose, lowering insulin levels. Another, eliminating intake of insulin-stimulating foods, such as sugar and refined carbohydrates. For hundreds of years, cancer has been portrayed as a foreign invader we've been powerless to stop. By reshaping our view of cancer as an internal uprising of our own healthy cells, we can begin to take back control. The seed of cancer may exist in all of us, but the power to change the soil is in our hands.

Post-transcriptional Mechanisms in Endocrine Regulation (Hardcover, 1st ed. 2016): K.M.J. Menon, PhD, Aaron Goldstrohm, PhD Post-transcriptional Mechanisms in Endocrine Regulation (Hardcover, 1st ed. 2016)
K.M.J. Menon, PhD, Aaron Goldstrohm, PhD
R6,200 Discovery Miles 62 000 Ships in 12 - 17 working days

This book examines how post-transcriptional mechanisms control endocrine function. This includes newly identified regulatory mechanisms involved in hormone biosynthesis, control of hormone receptors and the outputs of hormone mediated signal transduction. Chapters address endocrine hormones including protein peptide/peptide, steroid, and non-steroidal hormones. The impacts of these mechanisms on disease and health are covered, providing a novel update to the scientific literature. Post-transcriptional regulatory mechanisms play an essential role in controlling dynamic gene expression. The outcome of this regulation includes control of the amount, timing, and location of protein expression. Regulation is mediated by cis-acting RNA sequences and structures and transacting RNA binding proteins and non-coding RNAs, including microRNAs. Recent advances in characterization of these regulatory factors have revealed enormous regulatory potential.

Sleep has recently been recognized as a critical determinant of energy balance regulating, restoration and repair of many of the physiologic and psychologic processes involved in modulating energy intake and utilization. In addition to having an impact on obesity, sleep abnormalities, both quantitative and qualitative, have now been shown to have significant effects on obesity associated comorbidities, including metabolic syndrome, premalignant lesions and cancer. Sleep problems and fatigue also constitute a significant challenge for the ever expanding group of cancer survivors. Moreover, circadian misalignment, such as that experienced by "shift workers" has been shown to be associated with an increased incidence of several malignancies including, breast, colorectal and prostate cancer, consistent with the increasing recognition of the role of clock genes in the metabolic processes. Of increasing concern is the accelerating incidence of sleep disorders in childhood, their association with childhood obesity and associated abnormalities of circulating cytokines, adipokines and metabolic factors, many of which are implicated as etiologic mediators of the connection between obesity and cancer. Extensive studies have now been initiated to investigate the mechanisms by which disturbances in sleep duration, sleep continuity and sleep related breathing affect circadian rhythm, central and peripheral tissue oxygenation and metabolism, quality and quantity of dietary intake and circulating inflammatory cytokines and regulatory hormones. This volume aims to present the latest research on sleep, sleep disturbance and its correlation to obesity and cancer.

Melanie Bussey
R5,047 Discovery Miles 50 470 Ships in 12 - 17 working days

When working with sports men and women, the biomechanist is faced with two apparently incompatible goals: reducing injury risk and improving sports performance. Now in a fully updated and revised edition, Sports Biomechanics introduces the fundamental principles that underpin our understanding of the biomechanics of both sports injury and performance, and explains how contemporary biomechanical science can be used to meet both of those goals simultaneously. The first four chapters of this book look closely at sports injury, including topics such as the properties of biological materials, mechanisms of injury occurrence, risk reduction, and the estimation of forces in biological structures. The last four chapters concentrate on the biomechanical enhancement of sports performance including analytical techniques, statistical and mathematical modelling of sports movements, and the use of feedback to enhance sports performance. Drawing on the very latest empirical and epidemiological data, and including clear concise summaries, self test questions and guides to further reading in every chapter, this book is essential reading for all advanced undergraduate and postgraduate students with an interest in biomechanics, sports injury, sports medicine, physical therapy or performance analysis.

Slow Synaptic Responses and Modulation (Hardcover, 2000 ed.): K. Kuba, H. Higashida, DA Brown, T. Yoshioka Slow Synaptic Responses and Modulation (Hardcover, 2000 ed.)
K. Kuba, H. Higashida, DA Brown, T. Yoshioka
R1,681 Discovery Miles 16 810 Ships in 10 - 15 working days

Information flow as nerve impulses in neuronal circuits is regulated at synapses. The synapse is therefore a key element for information processing in the brain. Much attention has been given to fast synaptic transmission, which predominantly regulates impulse-to-impulse transmission. Slow synaptic transmission and modu lation, however, sometimes have been neglected in considering and attempting to understand brain function. Slow synaptic potentials and modulation occur with a considerable delay in response to the accumulation of synaptic and modulatory inputs. In these contexts, they are plastic in nature and play important roles in information processing in the brain. A symposium titled "Slow Synaptic Responses and Modulation" was held as the satellite symposium to the 75th Annual Meeting of the Physiological Society of Japan on March 30-31, 1998, in Kanazawa. The theme was selected not only for the reason mentioned above, but also because of the considerable involvement of many Japanese scholars in establishing the basic issues. Following the dawn of synaptic physiological research, as Sir John Eccles, Sir Bernard Katz, and Professor Stephen Kuffler carried out pioneer work, Professor Kyozou Koketsu and Professor Benjamin Libet, the students of Sir John Eccles, and their colleagues established the concept of slow synaptic responses and modulation by studying vertebrate sympathetic ganglia. Since then, the concept has been ex panded with detailed investigations of both peripheral and central synapses at the levels of single ion channels, intracellular Ca"+ dynamics, intracellular transduc tion mechanisms, and genes.

Mechanisms of Cortical Development (Hardcover): David Price, David Willshaw Mechanisms of Cortical Development (Hardcover)
David Price, David Willshaw
R6,638 Discovery Miles 66 380 Ships in 10 - 15 working days

This is the first book that attempts to bring together what is known about the fundamental mechanisms that underlie the development of the cortex in mammals. Ranging from the emergence of the forebrain from the neural plate to the functioning adult form, the authors draw on evidence from several species to provide a detailed description of processes at each stage. Where appropriate, evidence is extrapolated from non-mammalian species to generate hypotheses about mammalian development. In contrast to other texts of developmental biology, Mechanisms of Cortical Development integrates information on regulatory processes at the levels of molecules, cells and metworks. The authors draw together an extensive literature on cellular development and structural morphology, biochemical and genetic events and hypotheses that have been subject to mathematical modelling. Important metholdogies, such as transgenics and formal modelling, are explained for the non-specialist. Major future challenges are clearly identified. This is a unique contribution to the literature, combining the fundamentals of experimental developmental neurobiology with accessible neural modelling. It will be essential reading for neuroscientists in general as well as those with a particular interest in development.

Over the years there has been growing interest among the scientific community in investigating sleep and how it affects the memory and other brain functions. It is now well established that sleep helps in memory consolidation and induction of neural plasticity, and that short-term deprivation of either total sleep or rapid eye movement sleep alone can induce memory deficits very quickly. Quantitative and qualitative changes in sleep architecture after different training tasks further suggest that discrete memory types may require specific sleep stage/s for optimal memory consolidation, and studies indicate that sleep deprivation alters synaptic plasticity and membrane excitability in the hippocampal neurons and synaptic up-scaling in the cortical neurons. Further, sleep alteration during pregnancy may increase the risk of depression and adversely affect maternal-child relationships, parenting practices, family functioning, and children's development and general wellbeing. This book coherently discusses all these aspects, with a particular focus on the possible role of sleep in memory consolidation and synaptic plasticity. It also highlights the detrimental effects of sleep loss on mental health, the immune system and cognition. This book is a valuable reference resource for students and researchers working in the area of sleep, memory, or neuronal plasticity.

R5,971 Discovery Miles 59 710 Ships in 10 - 15 working days

This book assembles chapters from experts in the Biophysics of RNA to provide a broadly accessible snapshot of the current status of this rapidly expanding field. The 2006 Nobel Prize in Physiology or Medicine was awarded to the discoverers of RNA interference, highlighting just one example of a large number of non-protein coding RNAs. Because non-protein coding RNAs outnumber protein coding genes in mammals and other higher eukaryotes, it is now thought that the complexity of organisms is correlated with the fraction of their genome that encodes non-protein coding RNAs. Essential biological processes as diverse as cell differentiation, suppression of infecting viruses and parasitic transposons, higher-level organization of eukaryotic chromosomes, and gene expression itself are found to largely be directed by non-protein coding RNAs. The biophysical study of these RNAs employs X-ray crystallography, NMR, ensemble and single molecule fluorescence spectroscopy, optical tweezers, cryo-electron microscopy, and other quantitative tools. This emerging field has begun to unravel the molecular underpinnings of how RNAs fulfill their multitude of roles in sustaining cellular life. The physical and chemical understanding of RNA biology that results from biophysical studies is critical to our ability to harness RNAs for use in biotechnology and human therapy, a prospect that has recently spawned a multi-billion dollar industry.

At the Mie International Symposium held in Japan in April 1994, leading scientists reviewed recent advances in the understanding of the contractile mechanism in smooth muscle. The present volume collects the papers presented at the symposium, summarizing the latest advances in smooth muscle function and emphasizing important components of the contraction-relaxation cycle. Topics include a discussion of the smooth muscle cell membrane, with emphasis on its ion channels; the regulation of cytosolic Ca2+ levels and the relationship to force in smooth muscle; aspects of the two key regulatory enzymes involved with myosin phosphorylation-dephosphorylation; the molecular basis for pharmacomechanical coupling in smooth muscle; developments in the basic contractile mechanisms involving the crossbridge cycle of tonic and phasic muscle; the role of myosin light chains; and many others. The approach is broad and presents contemporary opinions in pharmacology, physiology, and biochemistry as they relate to smooth muscle function. The book will appeal not only to those working in these disciplines, but to vascular clinicians, obstetric-gynecological physicians, and gastroenterologists as well.

The human immune system is a complex network of tissues and organs dispersed throughout the body. Immunology, as one of the most rapidly evolving fields in bio-medical research, has to date covered the essential cellular and molecular events neces-sary for immune responses to occur. However, it has paid relatively little attention to important developmental processes underlying the formation of the tissues themselves that carry out immune responses in humans and other mammalians. In contrast to the thymus and bone marrow that are the sole tissues for generating mature leukocytes for antigen recognition and han-dling in humans and most mammalian species, the peripheral lymphoid tissues where adaptive immune responses are focused display broad tissue distribution and possess diverse archi-tectural characteristics. These organs develop prior to the individual s exposure to external antigens, and despite their similar functions, their varied appearances indicate a substantial complexity of tissue ontogeny. This volume presents a comprehensive overview of the developmental features of the major peripheral lymphoid organs, thus examining the connection between immunological functionality and structural characteristics utilizing a developmental approach, for an audience ranging from undergraduate students to senior researchers in immunology, histology and clinical medicine."

Cardiorespiratory function is prominently affected by oxidative stress. Cigarette smoking is the archetype of oxidative and nitrative stress and free radical formation. New adverse effects of smoking keep on propping up in research. The chapters provide the comprehensive view of new developments in this area regarding cardiovascular and lung function and muscle catabolism. Alterations in inflammatory cytokines and proteins as well as degradation of muscle proteins due to smoking, by far unrecognized, caused by oxidative stress also are presented. Much less is known about the effect of cognitive stress on vagally-mediated cardiorespiratory function and surprisingly, on vagal immune pathway. The experimental studies also show that clinically important meconium aspiration syndrome contains an oxidative trait which is amenable to antioxidative treatment. This volume creates a source of information on the damaging role of oxidative stress in cardiorespiratory function that has by far not been available.

Unraveling the functional properties of structural elements in the brain is one of the fundamental goals of neuroscientific research. In the cerebral cortex this is no mean feat, since cortical areas are defined microstructurally in post-mortem brains but functionally in living brains with electrophysiological or neuroimaging techniques - and cortical areas vary in their topographical properties across individual brains. Being able to map both microstructure and function in the same brains noninvasively in vivo would represent a huge leap forward. In recent years, high-field magnetic resonance imaging (MRI) technologies with spatial resolution below 0.5 mm have set the stage for this by detecting structural differences within the human cerebral cortex, beyond the Stria of Gennari. This provides the basis for an in vivo microanatomical brain map, with the enormous potential to make direct correlations between microstructure and function in living human brains. This book starts with Brodmann's post-mortem map published in the early 20th century, moves on to the almost forgotten microstructural maps of von Economo and Koskinas and the Vogt-Vogt school, sheds some light on more recent approaches that aim at mapping cortical areas noninvasively in living human brains, and culminates with the concept of "in vivo Brodmann mapping" using high-field MRI, which was introduced in the early 21st century.
