The human microbiome refers to the complete microorganisms inhabiting the human body sites including skin, ear, nose, oral cavity, the genital, gastrointestinal and respiratory tracts, and body fluids such as breast milk, saliva, and urine. It is a significant and essential organ recognized for the body and has an established involvement in the host wellbeing, in terms of nutritional requirements and immunomodulation. This book talks about how alteration and imbalance in the same can have clinical implications associated with a multitude of gastrointestinal, lifestyle-associated, and neurodegenerative disorders. How the proliferation of specific groups of bacteria and their metabolic activities, as a result of intestinal dysbiosis leads to the 'leaky gut' condition thereby influences brain activity via the bidirectional gut-brain axis. It also coves the importance of microbial seeding and how it can be influenced by the mode of delivery, nutrition, and medication. This book also provides various therapeutic interventions such as the establishment of stool banks and Faecal microbiota transplantation (FMT) that have recently proved promising in the treatment of ASD, Inflammatory Bowel Disease, and Ulcerative Colitis. This book provides a deeper understanding of the development of the human gut microbiome and the factors driving its dysbiosis. This book is a valuable read for health professionals, medical students, nutritionists, and scientific research communities who are eager to update themselves with recent trends in microbiome research. It will also aid gastroenterologists and nutritionists to make well-informed choices regarding therapeutic regimes.

Handbook of Basic and Clinical Ocular Pharmacology and Therapeutics provides a review of the basic anatomy, physiology, biochemistry and pathology of the eye with a focus drug therapy, drug delivery and use of therapeutic medical miniature devices. An understanding of the pharmacological actions of drugs acting on the eye requires the student and health care practitioner to learn additional principles in basic and clinical sciences that are unique to this organ. As a sensory organ, the eye is relatively inaccessible to the systemic circulation due to the blood-vitreous, blood-aqueous and blood-retinal barriers. Consequently, the administration of drugs for therapeutic effects in the eye necessitates an understanding of physico-chemical properties of the molecules and pharmacokinetic principles involved in the access to its site of action via topical, intracameral and intravitreal administration. This book includes information on the general principles of pharmacokinetics and pharmacodynamics of drugs as it pertains to the eye and in combating ocular disorders and diseases. Using a disease-themed approach, the book discusses basic and clinical pharmacological principles involved in the therapy of these diseases including the ocular side effect of systemically-administered drugs, drugs used in ophthalmic surgery and miscellaneous agents, the therapeutic utility of biologics, drug conjugates, combination products, gene and cellular therapy are also covered. Handbook of Basic and Clinical Ocular Pharmacology and Therapeutics is useful as a primary and secondary source of reference for up-to-date information about the pharmacological mechanisms of action, pharmacokinetics, side effects, drug-drug interactions and therapeutic indications of drugs for pharmacologists, pharmaceutical scientists, students in the health care disciplines (nursing, pharmacy, optometry, medical), and practitioners in optometry and ophthalmology. - Explains the mechanisms of action, side-effects and therapeutic uses of drugs, biologics, miniature devices, gene and cellular therapies for the eye - Provides a comprehensive review of the anatomy, physiology, biochemistry, pharmacology, microbiology, genetics and pathology of parts of the eye involved in drug therapy to combat eye disorders and diseases - Explores the pharmacological and clinical basis of drugs, drug conjugates, combination products used in the treatment of anterior and posterior segment diseases

Microbes, Microbial Metabolism and Mucosal Immunity: An Overview presents a concise and well-vetted treatise on the study of microbiome and microbial metabolites. This volume is up-to-date with the most recent developments from the last decade. It encompasses the interaction of immunity and microbes — and their metabolites — from different mucosal organs including gastrointestinal system, lung, oral cavity, eye. Along with the efficiency of the immune system in inhibiting the growth and proliferation of microbes, the volume discusses how the mediators of the immune system can be targeted to develop therapies.This book presents the latest methods, gives broad and systematic coverage of most mucosal systems and diseases, and takes a fresh perspective that looks at the functional aspects of change in the microbiome. The study of microbiome and microbial metabolites and their roles in host mucosal immunology is a rapidly developing area of research. One major way in which the microbiome influences the host is through altered metabolism. Metabolites, readily available to the host, engender significant consequences.
