Materials Development and Processing for Biomedical Applications focuses on various methods of manufacturing, surface modifications, and advancements in biomedical applications. This book examines in detail about five different aspects including, materials properties, development, processing, surface coatings, future perspectives and fabrication of advanced biomedical devices. Fundamental aspects are discussed to better understand the processing of various biomedical materials such as metals, ceramics, polymers, composites, etc. A wide range of surface treatments are covered in this book that will be helpful for the readers to understand the importance of surface treatments and their future ...
The aim of this book is to provide a comprehensive review of the use of Transcranial Direct Current Stimulation (tDCS) in different psychiatric conditions. Here we review tDCS clinical studies employing different types of design (from single-session tDCS studies to randomized clinical trials) as well as studies evaluating the impact of tDCS in neurophysiological, behavioral and brain imaging outcomes. Although the understanding about physiological foundations and effectiveness of clinical therapies of psychiatric diseases has been considerably increased during the last decades, our knowledge is still limited, and consequently psychiatric diseases are still a major burden to the individual pa...
"The definition of psychotic spectrum disorders such as schizophrenia has evolved with changing nosogy and scientific advancements over the last 200 years. Understanding both the historical evolution of the concept as well as recent changes reflected in the American Psychiatric Association's Diagnostic and Statistical Manual (DSM-5) as well as the National Institute of Health's (NIH) Research Domain Criteria (RDOC) framework are critical for informing current efforts to further update and refine the nosology of psychotic spectrum disorders. This chapter offers an overview of past classification schemes, current standards, and novel approaches to further improve the validity of these definitions through use of biomarkers, reverse nosologies, and digital phenotyping tools like smartphones and sensors"--
The 2nd edition of this book incorporates the tremendous clinical advances that have occurred in the field of transcranial direct current stimulation (tDCS) over the past 5 years. Since the 1st edition was published, the clinical use of tDCS has moved from its infancy, and is now in a thrilling new phase with numerous possibilities as well as challenges. tDCS is a technique that excels in terms of safety and tolerability, and within a few years, novel technological developments will allow its use at home. At the same time, large, phase III trials have been exploring the clinical efficacy of tDCS, the results of which have been published in leading journals such as the New England Journal of ...

The eBook entitled “Brain Stimulation and Behavioral Change” is a collection of articles about the use of transcranial electric stimulation (tES) to change behaviors and face pathological conditions, to enhance cognition and to explore cerebral functions using safe and non-invasive brain modulation techniques. The tESs include transcranial direct current stimulation (tDCS), transcranial alternate current stimulation (tACS), and, due to the way it induces changes in the brain, Transcranial Magnetic Stimulation (TMS). The use of tES has recently exploded. Certainly, one reason for this explosion of research is that it is a cheap way to change behavior. However, on the other hand, we still ...
Depression is a kind of affective disorder with a series of symptoms, such as significant and persistent depression, loss of pleasure, lack of motivation and so on (1). It has the characteristics of high prevalence rate, high suicide rate, high recurrence rate and high disability rate. Data show that as of February 2017, the global prevalence rate of depression has reached 4.4%, the lifetime prevalence rate is 16%, and the number of patients is as high as 322 million. The World Health Organization points out that depression will become the second leading cause of death and disability by 2020 (2), so the treatment of depression has become a hot and difficult issue in psychiatric clinic.
This book presents state of the art knowledge on the psychopathology, clinical symptomatology, biology, and treatment of hallucinations in patients with psychoses and affective disorders. The opening section describes and examines the origins of the hallucinatory symptoms associated with schizophrenia, bipolar disorders, and drug- or substance-induced psychoses. In addition, progress in understanding of hallucinations in children and adolescents and chronic hallucinatory disorder is reviewed, and the value of a Research Domain Criteria approach in elucidating the emergence of auditory hallucinations is explained. The biological basis of hallucinations is then closely scrutinized with reference to recent genetic research, neurochemical studies, and functional and structural neuroimaging data. Outcomes of a meta-analysis of diffusion tensor imaging studies regarding the association between white matter integrity and auditory verbal hallucinations are highlighted. The closing chapters focus on the roles of drug treatment and electric and magnetic brain stimulation techniques. The book will be of wide interest to psychiatrists and clinical psychologists.
Throughout history, man has, by over-use, consistently reduced the productive capacity of dry lands. This degradation of one-third of the land area of the globe is, unfortunately, increasing. In recent years, world interest has turned to the problems of pollution of the environment and the impending food shortage as world population grows explosively. Thus the attention of international and other agricultural bodies has turned to the need for preserving and developing more effectively the agricultural potential of these areas.This book provides a comprehensive review of present knowledge of the agriculture of dry lands, with special emphasis on measures for conserving their natural resources...
