Download or read book The Role of the Electrogenic Sodium Pump in Modulation of Pacemaker Discharge of Aplysia Neurons written by J. A. Willis and published by . This book was released on 1974 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discharge of Aplysia pacemaker neurons varies with temperature over the range of 10 to 22C. Three types of temperature-frequency plots are found, with maximal discharge at lowest, intermediate or highest temperatures. In the presence of ouabain, however, all cells show maximal discharge at the highest temperature, suggesting that the steady-state activity of an electrogenic sodium pump is an important determinant of membrane excitability. The average magnitude of pump current, as indicated by the applied current necessary to restore discharge to control values after ouabain application, was about 4nA at 20C but near zero at 10C. These neurons may be excellent models of mammalian thermoreceptors.

Download or read book The Sodium Pump written by Ernst Bamberg and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 924 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sodium of animal cell membranes converts the chemical energy obtained from the hydrolysis of adenosine 5' -triphosphate into a movement of the cations Na + and K + against an electrochemical gradient. The gradient is used subse quently as an energy source to drive the uptake of metabolic substrates in polar epithelial cells and to use it for purposes of communications in excitable cells. The biological importance of the sodium pump is evident from the fact that be tween 20-70% of the cell's metabolic energy is consumed for the pumping pro cess. Moreover, the sodium pump is an important biological system involved in regulatory processes like the maintenance of the cells' and organism's water me tabolism. It is therefore understandable that special cellular demands are han dled better by special isoforms of the sodium pump, that the expression of the sodium pump and their isoforms is regulated by hormones as is the activity of the sodium pump via hormone-regulated protein kinases. Additionally, the sodium pump itself seems to be a receptor for a putative new group of hormones, the endogenous digitalis-like substances, which still have to be defined in most cases in their structure. This group of substances has its chemically well known coun terpart in steroids from plant and toad origin which are generally known as "car diac glycosides". They are in medical use since at least 200 years in medicine in the treatment of heart diseases.

Available in PDF, EPUB and Kindle. Book excerpt: Basic Neurochemistry, Eighth Edition, is the updated version of the outstanding and comprehensive classic text on neurochemistry. For more than forty years, this text has been the worldwide standard for information on the biochemistry of the nervous system, serving as a resource for postgraduate trainees and teachers in neurology, psychiatry, and basic neuroscience, as well as for medical, graduate, and postgraduate students and instructors in the neurosciences. The text has evolved, as intended, with the science. This new edition continues to cover the basics of neurochemistry as in the earlier editions, along with expanded and additional coverage of new research from intracellular trafficking, stem cells, adult neurogenesis, regeneration, and lipid messengers. It contains expanded coverage of all major neurodegenerative and psychiatric disorders, including the neurochemistry of addiction, pain, and hearing and balance; the neurobiology of learning and memory; sleep; myelin structure, development, and disease; autism; and neuroimmunology. Completely updated text with new authors and material, and many entirely new chapters Over 400 fully revised figures in splendid color 61 chapters covering the range of cellular, molecular and medical neuroscience Translational science boxes emphasizing the connections between basic and clinical neuroscience Companion website at http://elsevierdirect.com/companions/9780123749475

Available in PDF, EPUB and Kindle. Book excerpt: The bicentenary of William Withering's now famous medical report entitled "An Account of the Foxglove and Some of its Medical Uses" has given us the occasion to analyze the state of the art. Cardiac glycosides in 1985 are considered tobe the basis for medical treatment of myocardial failure, together with diuretics and vasodilators in the more severe cases. Nevertheless, the controversy as to their exact place in the treatment of heart failure with sinus rhythm has never ceased. Although cardiac glycosides are of unquestionable value in tachycardia caused by atrial fibrillation or atrial flutter, the chronic use of these drugs in sinus rhythm is not generally accepted. The development of tolerance has been reported. It is of interest that Withering hirnself wrote: "-let it (foxglove) be continued until it either acts on the kidneys, the stomach, the pulse, or the bowels; Iet it be stopped upon the first appearance of any of these effects, and I will maintain that the patient will not suffer from its exhibition, nor the practitioner be disappointed in any reasonable expectation. " In West Germany alone, more than three million patients (about 5% of the total population) are constantly taking cardiac glycosides. These drugs are the most prescribed medicaments in many countries. Thus, we considered it worthwhile and necessary to review in a critical way today's knowledge about the foxglove; to report new findings and to evaluate old Statements.
