Body Messages
The Quest for the Proteins of Cellular Communication
Giamila Fantuzzi
Harvard University Press, 2016

Whether classified as regulators of inflammation, metabolism, or other physiological functions, a distinctive set of molecules enables the human body to convey information from one cell to another. An in-depth primer on the molecular mediators that coordinate complex bodily processes, Body Messages provides fresh insight into how biologists first identified this special class of molecules and the consequences of their discovery for modern medicine.

Focusing on proteins that regulate inflammation and metabolism—including the cytokines and adipokines at the core of her own research—Giamila Fantuzzi examines the role body messages play in the physiology of health as well as in the pathology of various illnesses. Readers are introduced to different ways of conceptualizing biomedical research and to the advantages and pitfalls associated with identifying molecules beginning with function or structure. By bringing together areas of research usually studied separately, Fantuzzi stresses the importance of investigating the body as a whole and affirms the futility of trying to separate basic from clinical research. Drawing on firsthand interviews with researchers who made major contributions to the field, Body Messages illustrates that the paths leading to scientific discovery are rarely direct, nor are they always the only routes available.

Diving Seals and Meditating Yogis
Strategic Metabolic Retreats
Robert Elsner
University of Chicago Press, 2015
The comparative physiology of seemingly disparate organisms often serves as a surprising pathway to biological enlightenment. How appropriate, then, that Robert Elsner sheds new light on the remarkable physiology of diving seals through comparison with members of our own species on quests toward enlightenment: meditating yogis.

As Elsner reveals, survival in extreme conditions such as those faced by seals is often not about running for cover or coming up for air, but rather about working within the confines of an environment and suppressing normal bodily function. Animals in this withdrawn state display reduced resting metabolic rates and are temporarily less dependent upon customary levels of oxygen. For diving seals—creatures especially well-adapted to prolonged submergence in the ocean’s cold depths—such periods of rest lengthen dive endurance. But while human divers share modest, brief adjustments of suppressed metabolism with diving seals, it is the practiced response achieved during deep meditation that is characterized by metabolic rates well below normal levels, sometimes even approaching those of non-exercising diving seals. And the comparison does not end here: hibernating animals, infants during birth, near-drowning victims, and clams at low tide all also display similarly reduced metabolisms.

By investigating these states—and the regulatory functions that help maintain them—across a range of species, Elsner offers suggestive insight into the linked biology of survival and well-being.

How Fat Works
Philip A. Wood
Harvard University Press, 2006
An experimental pathologist and molecular geneticist, Philip Wood uses gene-knockout technology to study the way mouse genes regulate the metabolism of fat—research that provides insights into the workings of fatty-acid metabolism in humans and what can happen when that metabolic balance goes awry. Based on the classes he regularly teaches to first- and second-year medical students, Wood's book reviews the individual and public health burden of obesity and clarifies often-used, but often inadequately explained, terms employed in the continuing cultural and scientific debate about excess fat. He explains the role of fat in the healthy body, how fat is made, stored, and burned, and demonstrates how excess fat can lead to an array of metabolic disorders and diseases, from hypercholesterolemia and insulin resistance to diabetes. He reviews what recent research can tell us about specific genes or groups of genes that can lead to specific metabolic disorders. He explains the science behind common weight-loss regimens and why those regimens might succeed or fail, and reviews the complex interplay of hormones, genes, and stress in the way our bodies deal with fat through the life cycle. How Fat Works is a concise, clear, and up-to-date primer on the workings of fat, and essential reading for professionals entering careers in medicine and public health administration or anyone wanting a better understanding of one of our most urgent health crises.

Metabolic Arrest and the Control of Biological Time
Peter W. Hochachka and Michael Guppy
Harvard University Press, 1987

Freshwater turtles and goldfish can survive for several days without oxygen, some diving turtles for several months; hibernating animals can exist without food for long periods; others can survive extreme conditions such as desiccation, freezing, and thawing. These creatures are, in effect, self-sustaining life-support systems, with a mysterious ability to regulate their own metabolisms.

These capabilities raise important questions, which Hochachka and Guppy explore in this seminal new book. What mechanisms turn down (or off) cell metabolism and other cell functions? How does an animal such as an opossum know when to activate mechanisms for slowing or stopping tissue and organ functions? How does it know when to turn them on again? How extensive is metabolic arrest as a defense against harsh environmental conditions? Can we decipher universal principles of metabolic arrest from available data? The lessons to be learned are of potentially great interest to clinicians, because the authors provide a theoretical framework in which to organize an attack on the all-too-practical problem of protecting tissues against hypoxia. Areas that may be influenced include research on cardiac arrest, strokes, acute renal failure, liver ischemia, lung injury, respiratory defense syndrome, claudication, shock, and organ transplant. Investigation of other metabolic arrest mechanisms may be similarly useful in both clinical and agricultural fields.

This is a pioneering book of great use to biomedical/clinical researchers and to biologists, biochemists, and physiologists generally.

Food, Fat, and the Absorption of Illness in India
Harris Solomon
Duke University Press, 2016
The popular narrative of "globesity" posits that the adoption of Western diets is intensifying obesity and diabetes in the Global South and that disordered metabolisms are the embodied consequence of globalization and excess. In Metabolic Living Harris Solomon recasts these narratives by examining how people in Mumbai, India, experience the porosity between food, fat, the body, and the city. Solomon contends that obesity and diabetes pose a problem of absorption between body and environment. Drawing on ethnographic fieldwork carried out in Mumbai's home kitchens, metabolic disorder clinics, food companies, markets, and social services, he details the absorption of everything from snack foods and mangoes to insulin, stress, and pollutants. As these substances pass between the city and the body and blur the two domains, the onset and treatment of metabolic illness raise questions about who has the power to decide what goes into bodies and when food means life. Evoking metabolism as a condition of contemporary urban life and a vital political analytic, Solomon illuminates the lived predicaments of obesity and diabetes, and reorients our understanding of chronic illness in India and beyond.

Studies in the Metabolism of Vitamin B12
Alfred Doscherholmen
University of Minnesota Press, 1965
Studies in the Metabolism of Vitamin B12 was first published in 1965.Dr. Doscherholmen has conducted extensive studies of the physiological aspects of vitamin B12 metabolism in man, and in this book he describes the investigations, reports the findings, and reviews the literature. He also reports on laboratory animal studies which contribute to a knowledge of the subject.The major investigations were performed in a clinical setting and involved the administration of doses of radiocyanocobalamin, the radioactive form of vitamin B12, to patients offlicted with various diseases and to normal subjects. In order to diagnose malabsorption of B12, the Schilling test was performed on patients having pernicious anemia, partial or total gastrectomy, histamine-fasct achlorhydria, posterolateral column disease without anemia, intestinal megaloblastic anemia, regional ileitis, sprue, secondary steatorrhea, cirrhosis of the liver, leukemia, and various types of neuritis.The author assesses the most commonly used methods of testing B12 absorption, the urinary excretion test, and reports his attempts to improve the urinary recovery of radioactivity. He describes a new technique for the measurement of B12 absorption -- the plasma absorption test -- and evaluates its clinical usefulness. He also reports on studies of the basic mechanism of the Schilling test, the organ distribution of radioactivity, and the kinetics of cyanocobalamin in man after the oral ingestion of physiologic doses of radiocyanocobalamin. Additional studies described are concerned with the B12 binding power of serum as determined through an ultrafiltration technique, the enzymatic release of B12 in the small intestine of rats, and the hepatic storage of radiocyanocobalamin. There is an extensive bibliography.
