Abstract

Serotonin - A Chemical Messenger Between All Types of Living Cells is a very interesting book on the most ancient neurotransmitter, hormone and trophic factor serotonin or 5-hydroxytryptamine (5-HT). This unique chemical is present in all living cells including plants and animals. This book will take us through a serene journey of the evolutionary history of serotonin and its role from man to mollusk. There are many interesting chapters incorporated in this book, including novel approaches for detecting minor metabolites of serotonin in human plasma, production and function of serotonin in cardiac cells, immuno-thrombotic effects of serotonin in platelets to the identification and localization of serotonin in the nervous system and gonad of bivalve mollusks.

Abstract

Scientific interest in cannabinoid research is currently experiencing a significant increase because of changing attitudes toward Cannabis and the evolving awareness of its pharmaceutical benefits. Coincidently, numerous jurisdictions are moving toward legalizing Cannabis and Cannabis-derived products, which reflects a larger global movement to understand Cannabis and its bioactive chemicals for their potential biomedical uses, harms, and economic value. Research activities are surging to fill important knowledge gaps in the field of cannabinoids as they continue to be identified. The purpose of this book is to summarize some leading areas of research in the cannabinoid field where knowledge gaps are actively being addressed. The research described herein spans basic biological and clinical research.

Abstract

Alzheimer disease (AD) is a neurodegenerative disorder characterized by significant cognitive deficits, behavioral changes, sleep disorders and loss of functional autonomy. AD represents the main cause of dementia and has become a major public health issue. In addition, the number of patients suffering from AD is growing rapidly as the population ages worldwide. Memory impairment is usually the earliest clinical and core symptom of this disease. The diagnosis at a late clinical stage is relatively easy. However, a delay in the diagnosis is damageable for the handling of patients in terms of optimal medical and social care. The actual interest of the scientific head-ways is to optimize the diagnosis in prodromal stage of the disease and to propose personalized therapeutic solutions to individual patients. New revised AD diagnostic criteria include early alteration of cerebrospinal fluid (CSF) biomarkers: decrease of amyloïd peptides (Aß42), and increase in tau and phosphorylated-tau (p-tau) protein concentration. This recognition of CSF biological biomarkers for the diagnosis of AD is a major step towards the “molecular” diagnosis and follow-up of the disease. Many issues are however still subject of debate. This e-book provides a comprehensive overview of the state of the art of fluid biomarkers for AD, e.g. which novel biomarkers should be implemented in clinical practice for diagnosis or for monitoring treatment or side effects, which ones are new for AD or related dementias or what is the potential of peripheral blood markers. Moreover, the e-Book provides practical guidelines how to optimally and efficiently develop and validate novel biomarker assays, and to document and control pre-analytical variation.

Abstract

Neuropsychiatric disorders, covering both psychotic and depressive disorders, but also autism and attention-deficit hyperactivity disorder (ADHD), are characterized by abnormal behavior and brain structure. Accumulating evidence suggests that altered neurochemistry plays a role in these disorders and may have a causal relationship with the observed behavioral and structural abnormalities. To improve the understanding of neurochemical anomalies and (patho)physiological changes in psychiatric conditions, in vivo assessment of the affected tissue, the brain, is wanted and needed. Magnetic resonance spectroscopy (MRS) is a non-invasive technique which allows in vivo assessment of the molecular composition of brain tissues and identification of metabolites involved in physiological and pathological processes, which is otherwise virtually impossible. Only in the last decade with the development of high field MR methodologies, MRS has become sensitive enough for broader use in clinical studies. The implications are many, but proper guidance and elucidation of the pros and cons for the specific methods is needed to optimally exploit the potential.This Research Topic updates the reader on the possibilities and pitfalls of MRS today and highlights methodologies and applications for the future.
