Membrane transporters are of vital importance for cells. They mediate the flux of many substances through the plasma membrane. In this book, the transporters for organic cations, a special class of membrane transporters, are presented. Transporters belonging to this class are important because they allow many neurotransmitters (e.g., histamine and serotonin) and many drugs (e.g., trospium and tofacitinib) to permeate the plasma membrane. Therefore, transporters for organic cations can modulate the action of neurotransmitters and drugs, having in this way important physiological and pharmacological implications. These aspects are illustrated in original works and reviews presented in this boo...
This innovative text explores the cellular transport of organic cations, from functional and structural properties to pharmacological implications and psychiatric developments. The authoritative chapters introduce organic cation transporters and then proceed to discuss their mechanisms such as binding of substrates and inhibitors; their drug dispositions and toxicity; their relationships to genetic and pathophysiological variability; and their roles in endocrine, metabolic, and neurological systems. The final chapters delve into the use of animal models for the study of organic cation transporter function and their possible use in environmental cycling of pharmaceutical residues. This comprehensive volume unites integrative transporter physiology with structural and molecular biology, genetics, pharmacology and pathophysiology, offering a holistic approach to utilizing this novel technique in physiological contexts. It will prove invaluable reading for researchers and students in various areas of integrative, organ, cell and molecular physiology as well as pharmacologists and neurologists.
Around one third of all biologically relevant small molecules are organic cations. These include endogenous substances like catecholamines and other neurotransmitters, toxins and drugs designed to affect signaling processes. The organic cation transporter 1 (OCT1) is among the strongest expressed membrane transporters at the sinusoidal (blood-facing) side of liver cells and contributes substantially to the clearance of the blood from numerous organic cations. A most striking feature of OCT1 is its pronounced genetic diversity. Between 1 and 10% of all human populations have little to no OCT1 activity. With several of the OCT1 substrates up to 10% of Europeans are functionally OCT1 deficient....
Current Topics in Membranes is targeted toward scientists and researchers in biochemistry and molecular and cellular biology, providing the necessary membrane research to assist them in understanding the current state and future prospects of a particular field. This volume on exchangers, in conjunction with a previous volume on cotransporters (volume 70), represents an up-to-date, systematic, and comprehensive review of all the major secondary active carrier proteins responsible for the absorption, secretion, and general transport of ions and solutes in mammalian organ systems and additional species. Each chapter is devoted to a specific transporter or a grouping of related transporters based on the well-recognized nomenclature of the SoLute Carrier (SLC) gene family. This book provides readers with the latest mechanistic information on the function and structure of specific transporters, as well as their history and physiological significance. Comprehensive review of all the major exchangers Emphasis on protein mechanism with the most recent findings from functional and structural work Authoritative work from experts in the field
In recent years, artificial intelligence has increasingly been playing an essential role in diverse areas in medicine, assisting clinicians in patient management. In nephrology and transplantation, artificial intelligence can be utilized to enhance clinical care, such as through hemodialysis prescriptions and the follow-up of kidney transplant patients. Furthermore, there are rapidly expanding applications and validations of comprehensive, computerized medical records and related databases, including national registries, health insurance, and drug prescriptions. For this Special Issue, we made a call to action to stimulate researchers and clinicians to submit their invaluable works and present, here, a collection of articles covering original clinical research (single- or multi-center), database studies from registries, meta-analyses, and artificial intelligence research in nephrology including acute kidney injury, electrolytes and acid–base, chronic kidney disease, glomerular disease, dialysis, and transplantation that will provide additional knowledge and skills in the field of nephrology and transplantation toward improving patient outcomes.
The here presented book covers different areas of clinical and scientific interest, reaching from donor evaluation to newest methods in immunological diagnostics. But also aspects of daily care of transplant recipients can be found in the carefully selected chapters. Everything driven by the aim to improve the care for all of our transplanted patients.
Each volume in this series contains transcriptions of passenger lists containing German surnames for ships entering all US ports beginning in 1840. Lists are arranged by date of ship arrival and are indexed by passenger names. This volume covers the period from January 2, 1840 to June 1843.
