This book intends to strike a balance between developments in pharmacotherapy research and the facts that researchers must absorb, as well as link scientific advances with clinical practice so that the management of diseases can be based on sound physiological concepts. Each chapter has been reviewed and new authors have brought up-to-date research to make the book more informative, illustrative, and easy to read. The book focuses on three major areas: Experimental, preclinical, and clinical applications of herbal medicine; Evidence-based strategies in emergency medicine and New approach in management of psychiatric disorders. The first three chapters describe new and modern applications of common herbs for treatment of several inflammatory and skin disorders, e.g. ulcerative colitis, bronchial asthma, osteoarthritis, multiple sclerosis, and melasma. Chapter four deals with the most severe hypertensive states that pose an immediate threat to life, and how to manage these situations. The fifth chapter is dedicated to tackling polypharmacy psychiatric disorders. We hope this book is useful to a wide range of readers, from students first learning about pharmacotherapy, through advanced clinicians and researchers who are looking for a review of current treatments and conceptualizations of the condition. It is our hope that this book may motivate readers to approach the evidence on pharmacotherapy with an open mind, and thereby spark an interest in initiating further contributions to the current scientific debate and treatment development efforts.

High-speed optical communication is very much useful in telecommunication systems, data processing and networking. It consists of a transmitter that encodes a message into an optical signal, a channel that carries this optical signal to its desired destination, and a receiver that reproduces the message from the received optical signal. It presents up to date results on communication systems, along with the explanations of their relevance, from leading researchers in this field. The chapters of this book cover general concepts of high-speed optical communication, optical devices used optical communication, and optical communication systems. In recent years, optical devices and other enhanced signal processing functions are also considered in depth for high-speed optical communications systems. Commonly used optical devices are light emitting diodes and photodetectors. This book is targeted at research, development and design engineers from the teams in manufacturing industry, academia and telecommunication industries.

Chronology is the backbone of history, and there is a wise saying stating there is no history without a chronology. Earths evolutionary history is built up by geochronology, i.e. time benchmarks upon which the geological history is built up step by step over its total time period of about 4.5 billion years. The first marker in this history is the Jack Hills zircon from Australia dated at about 4.4 GA. The most detailed records come from seasonal changes within annual varves. Stratigraphy provides the basic chronological ordering of layers by layers, units by units, fossil assemblage by assemblage, varves by varves, growth zone by growth zone, etc. The radiometric techniques implied the introduction of absolute age determinations. This book includes a combination of methodological presentations and related case studies, from where we learn about practical problems and achievements. Therefore, the book should be of basic interest both for scientists in their practical in field and laboratory, as well as for general educational purpose.

Tissue-specific stem cells have the capacity to self-renew and differentiate into several types of functional cells that replenish lost cells throughout an organism?s lifetime. Studies on stem cells from diverse systems have shown that stem cell function is controlled by extracellular cues from the niche and by intrinsic genetic programs within the stem cell. The objectives of this book would be to review the molecular mechanisms that mediate the balanced response of stem cells to the needs of the organisms. Likewise, niches have also been linked to pathologies, by imposing aberrant function on stem cells or other targets. Therefore, the second objective of this book would be to highligh the molecular dysregulation of niche biology leading to the disease. The third objective would be to review the therapeutical targets described within stem cell niches.

Chronic Obstructive Pulmonary Disease (COPD) is an increasingly recognized cause of morbidity and mortality. Over the next 10 years, deaths due to COPD are expected to increase by 30% and, by 2030, COPD is estimated to be the third leading cause of death worldwide. Research into the pathophysiology and management of COPD over the past decade has progressed immensely with greater understanding of the global burden of COPD, its pathophysiology, better understanding of the multisystemic manifestations of COPD, and, most importantly, novel and more effective therapeutic strategies. This volume brings together an international group of experts in COPD to provide in depth reviews of clinical perspectives into COPD. Topics range from the diagnosis of airflow limitation by spirometry; distinguishing COPD from another common obstructive lung disease, asthma; alpha-1-antitrypsin deficiency and opportunities to diagnose this most common hereditary cause of COPD and as a paradigm for the development of novel therapeutics; the overlap syndrome - the concurrence of two epidemic disorders: COPD and obstructive sleep apnea; and pulmonary rehabilitation, one of the most effective treatments for COPD.

Most tissues and organs, such as the brain, need glucose constantly, as an important source of energy. The low blood concentrations of glucose (hypoglycemia) can cause seizures, loss of consciousness, and death. On the other hand, long lasting elevation of blood glucose concentrations (hyperglycemia) can result in blindness, renal failure, cardiac and peripheral vascular disease, and neuropathy. Therefore, blood glucose concentrations need to be maintained within narrow limits. The process of maintaining blood glucose at a steady-state level is called glucose homeostasis. This is accomplished by the finely hormone regulation of peripheral glucose uptake (glucose utilization), hepatic glucose production and glucose uptake during carbohydrates ingestion.

Although Obsessive-Compulsive Disorder (OCD) has been known since the ancient times, the exact etiology and pathogenesis of OCD unfortunately still remain unknown. In addition, the therapeutic approaches elaborated for the treatment of OCD as a whole are not perfect, and this disorder as a rule is characterized by unfavorable course and lack of full therapeutic response. In the current book some modern data on pathogenesis, phenomenology and treatment of OCD are presented. Besides, the data on co-morbidity of OCD with other neurological and psychiatric disorders are also included. This book is intended for broad circle of readers, but mostly for psychiatrists, psychologists and neurologists.
