Alzheimers disease is a neuro degenerative disorder. Medications namely done penile, galantamine and rivastigmine increase the levels of acetyl choline, a neurotransmitter that plays a critical role particularly in memory and learning. By stopping the enzymes that break down acetyl choline, these drugs increase communication between nerve cells in the brain. NMDA receptor antagonist that is meantime is also used in the treatment of Alzheimers disease.
Antiarrhythmic drugs play a key role regarding abnormal heart rhythms. Anti-arrhythmic drugs are divided into different classes dependent on their primary mechanism of action. These drugs are regarded as into four main categories such as class I (sodium channel blockers), class II(beta _ blockers), class III (potassium channel blockers) and class IV (calcium channel blockers). Class I anti arrhythmics specifically act on sodium channels, which play a role in the initiation and conduction of action potentials particularly in Cardiac cells. Class II anti arrhythmics act by decreasing the effects of adrenaline on the heart. Class III antiarrhythmics affect potassium channels and carry on the repolarization phase of the Cardiac action potential. Potential class IV antiarthmics stop calcium influx during depolarization and result in acdecrement in the heart rate and the forcec of contraction. Finally it is concluded that anti arrhythmic drugs play a critical role in managing various vtyoes of arrhythmias.
Acute and chronic hypoxia results in unconsciousness. Brain death happens immediately without proper treatment. Hypoxia activates Juxta glomerular (JG) apparatus of kidneys and enhances the secretion of erythroietin which in turn activates the red bone marrow to enhance the RBC count. Hypoxia enhances the rate and force of contraction of heart, cardiac output (COP) as well as blood pressure. Hypoxia enhances the respiratory because of the stimulation of chemoreceptor reflex.
ACT Heart failure remains a significant health challenge globally, influencing millions of individuals and imposing a considerable burden on healthcare systems. Factors influencing heart failure include Cardiac remodeling, neuro hormonal activation, impaired contractility as well as ejection fraction, ventricular dysfunction as well as chamber dilation, inflammatory as well as oxidative stress, endothelial dysfunction and microbial dysfunction. Finally it is concluded that heart failure is a complex syndrome resulting from multiple pathophysiological mechanisms.
In most cases, Hepatitis B causes both inflammation and infection. Chronic cases result in irreversible liver damage as the virus attacks the liver over time without being noticed. The authors provide information regarding symptoms, early symptoms, diagnosis and treatment.
Amylin deciphers amylin's physiology and reveals previously unrecognized mechanisms fundamental to control body weight and fuel homeostasis. This book also discusses therapeutic utility of amylin as the first new medicine to treat diabetes since insulin. Provides a current comprehensive treatment of amylin the hormone Identifies the majority of amylin's physiologic functions
Pharmacology is a component of Encyclopedia of Biological, Physiological and Health Sciences in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Pharmacology is the study of the actions of chemicals on the body and most usually it is defined as chemicals that can have a therapeutic action to treat disease. Since it looks at the interaction between chemicals and body systems pharmacology utilizes the basic disciplines of chemistry, biochemistry, physiology, pathology and microbiology in its practice. Pharmacology is a foundation science for pharmacy which is the rational prescribing of drugs to treat disease and the foundation science for toxicology which is the study of the toxic actions of chemicals on the body. The two volumes are organized in groups of chapters as follows: The first group of chapters discuss pharmacological principles and these include chapters on Pharmacodynamics; Pharmacokinetics, Neuropharmacology, Autonomic Pharmacology and Clinical Pharmacology. The second group of chapters discusses the processes of Drug discovery and the Safety requirements for drugs to be used therapeutically and include Drug Discovery and Safety Pharmacology assessment. The largest group of chapters discuss different therapeutic areas and include Cardiovascular and renal pharmacology; Endocrine pharmacology; Neuropsychopharmacology; Pulmonary Pharmacology; Gastrointestinal pharmacology; Poisons venoms and toxins; Drugs on skeletal muscle; the Pharmacotherapy of inflammation; Reproductive pharmacology; Pain pharmacology and analgesia. The final group of chapters discuss new approaches and include Pharmacogenetics and pharmacogenomics; Immunopharmacology and Gene therapy. These two volumes are aimed at the following a wide spectrum of audiences from the merely curious to those seeking in-depth knowledge: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.
The new edition of this popular, well-established textbook addresses the expanding role of the pharmacist in treating patients. It covers treatment of common diseases as well as other medical, therapeutic and patient related issues. Written by both pharmacists and clinicians to reflect a team approach, it offers an in-depth analysis of drug therapy in the treatment of disease, relying on input from the pharmacist as a member of the "team" in hospital and community settings. Information is easy to locate in a logical format organized primarily by systems and disorders.
This new fifth edition of Information Resources in Toxicology offers a consolidated entry portal for the study, research, and practice of toxicology. Both volumes represents a unique, wide-ranging, curated, international, annotated bibliography, and directory of major resources in toxicology and allied fields such as environmental and occupational health, chemical safety, and risk assessment. The editors and authors are among the leaders of the profession sharing their cumulative wisdom in toxicology's subdisciplines. This edition keeps pace with the digital world in directing and linking readers to relevant websites and other online tools.Due to the increasing size of the hardcopy publication, the current edition has been divided into two volumes to make it easier to handle and consult. Volume 1: Background, Resources, and Tools, arranged in 5 parts, begins with chapters on the science of toxicology, its history, and informatics framework in Part 1. Part 2 continues with chapters organized by more specific subject such as cancer, clinical toxicology, genetic toxicology, etc. The categorization of chapters by resource format, for example, journals and newsletters, technical reports, organizations constitutes Part 3. Part 4 further considers toxicology's presence via the Internet, databases, and software tools. Among the miscellaneous topics in the concluding Part 5 are laws and regulations, professional education, grants and funding, and patents. Volume 2: The Global Arena offers contributed chapters focusing on the toxicology contributions of over 40 countries, followed by a glossary of toxicological terms and an appendix of popular quotations related to the field.The book, offered in both print and electronic formats, is carefully structured, indexed, and cross-referenced to enable users to easily find answers to their questions or serendipitously locate useful knowledge they were not originally aware they needed. Among the many timely topics receiving increased emphasis are disaster preparedness, nanotechnology, -omics, risk assessment, societal implications such as ethics and the precautionary principle, climate change, and children's environmental health. - Introductory chapters provide a backdrop to the science of toxicology, its history, the origin and status of toxicoinformatics, and starting points for identifying resources - Offers an extensive array of chapters organized by subject, each highlighting resources such as journals, databases,organizations, and review articles - Includes chapters with an emphasis on format such as government reports, general interest publications, blogs, and audiovisuals - Explores recent internet trends, web-based databases, and software tools in a section on the online environment - Concludes with a miscellany of special topics such as laws and regulations, chemical hazard communication resources, careers and professional education, K-12 resources, funding, poison control centers, and patents - Paired with Volume Two, which focuses on global resources, this set offers the most comprehensive compendium of print, digital, and organizational resources in the toxicological sciences with over 120 chapters contributions by experts and leaders in the field
