Thyroid hormones are involved in numerous physiological processes as regulators of metabolism, bone remodeling, cardiac function and mental status. Moreover, thyroid hormones are of special importance in fetal development, more particularly, in the development of the brain. Thus, maintenance of normal thyroid functioning is essential for psychological, biochemical, immunological, endocrinal and physiological well being of the body as well as normal growth and development. Understanding how the thyroid gland is affected by adverse factors can help clinicians to handle emergency situations or apply preventive care measures to patients. Thyroid Toxicity is a comprehensive monograph on thyroid toxicology. It gathers all information about the toxic effects of different kinds of factors (hormonal, radiation and chemical) that affect the thyroid system. The ebook gives a brief introduction to the thyroid system and answers several important questions about the topic such as the biochemical mechanisms through which various compounds (for example, pesticides, food additives, etc.) induce toxicity on the thyroid gland, how endocrine disruption alters the physiology of the human body and brain as well as how radiation harms the thyroid gland. Thyroid Toxicity is the definitive reference for any medical officer, endocrinologist, or toxicologist seeking knowledge on thyroid gland toxicology.

The gastrointestinal tract is a series of organs each with distinct mechanical functions. Each organ within the system brings food contents in the gut lumen to the site of absorption through separate mechanical functions. These mechanical functions are generated by a fine-tuned interaction between neuronal networks and active muscle layers. The passive components of the gastrointestinal wall such as the collagen-rich submucosa also play an important role in these mechanical actions. Clinical Mechanics in The Gut provides a thorough understanding of the anatomy and biomechanics of the physiological function and pathophysiology of the gastrointestinal tract. The book first gives an introduction to readers about the physical geometry of the gastrointestinal tract followed by a detailed explanation of biomechanical theory and its application to approximating and modeling gut mechanics. This is expanded further by detailed explanations of gut muscle and motor nerve functions in proceeding chapters. A biomechanical evaluation of disorders of regulatory mechanisms such as achalasia and Hirschsprung disease and disorders of effector mechanisms such as reflux disease, systemic sclerosis of the gastrointestinal tract and colonic diverticular disease are also included. Readers will, therefore, gain an understanding about clinical problems in gastroenterology from a bioengineering and modeling perspective. Clinical Mechanics in The Gut is a useful reference for gastroenterology researchers, biomedical engineers and systems biologists seeking to understand the physiology of the gut and applying this knowledge to surgical procedures, computer-based modeling systems and robotics.

Liver cancer, cirrhosis and nonalcoholic fatty liver disease are observed predominately in men. Being male or female is believed to be an important human variable that affects health and liver disease throughout the life span. However, few works have been published on the biological mechanisms underlying gender specific differences in liver disease. Several mechanisms underlying sex-associated differences of progression of liver disease are demonstrated in this e-book based on biological factors as estrogen and hepatic iron stores. Readers will gain a better understanding of the pathogenesis of these sex-associated differences in liver disease and on how to design healthcare for liver disease more effectively for individuals belonging to both genders. The e-book should be a useful reference on gender specific medicine for counselors and clinicians as well as for patients with chronic liver disease.

Acute and chronic liver disease is a global endemic healthcare concern. More than 500 million people around the world are infected with the hepatitis B or C virus. Approximately 500,000 patients die of hepatocellular carcinoma every year, implying that trained healthcare professionals and facilities for liver disease patients is a critical issue. Although promising therapies have been developed for viral hepatitis infections, management of liver cirrhosis, and hepatocellular carcinoma yet many patients suffer due to lack of adequate healthcare by professional hepatologists. This means that primary care physicians should be informed about diagnosing liver disease and the early management of viral hepatitis and hepatocellular carcinoma. Comprehensive Practical Hepatology provides readers current standard primary care guidelines for treatment and early stage management of patients with liver function abnormalities. This book provides a practical approach for physicians to apply on patients with apparent liver function abnormalities. The guidelines also cover: Acute and chronic liver injury, Information about the liver in systemic diseases, Drug usage in liver diseases, Surgical risk in liver disease patients, and, Recommendations for pregnant as well as elderly patients. Comprehensive Practical Hepatology thus provides complete practical advice on the management of liver diseases to non-hepatologists and general physicians.
