Extractions: Vom Leck in der Zellmembran Die Zellen unseres Nervensystems, aber auch Muskulatur und Herz werden durch schnelle Schwankungen ihres elektrischen Potenzials aktiviert. Dafür sind in ihre Membran Proteine eingelagert, die sich bei Bedarf zu einer Pore öffnen können, durch die geladene Salzteilchen (Ionen) fließen. Diese "Ionenkanäle" bestimmen Dauer und Intensität der Aktivierung. Seit langem ist bekannt, dass die Leitfähigkeit für Kalium-Ionen dabei eine besondere Rolle spielt: sie stabilisieren das Membranpotential bei negativen Werten und wirken im Ruhezustand einer Erregung der Zellen entgegen. Diese "Leck-Leitfähigkeit" wurde unter anderem von Sir Bernhard Katz bereits in den vierziger Jahren beschrieben. Dr. Noam Zilberberg geht der Frage nach, wie die elektrische Erregbarkeit verschiedener Zellen im Organismus durch eine spezielle Art von Kalium-Kanälen reguliert wird. Er hat die biophysikalischen Vorgänge bei der Ionenleitung durch die Kanäle analysiert, ihre Regulation durch verschiedene zelluläre Signalmoleküle (sog. Phosphokinasen) und den pH untersucht sowie die molekularen Signale, die den Einbau der Kanäle in die Zellmembran steuern. Auch war er an der Entdeckung weiterer verwandter Moleküle beteiligt, so dass heute eine Fülle von Genen bekannt ist, die in verschiedenen Spezies über 50 verschiedene solcher Ionenkanäle kodieren ("2-Poren-Domänen-Kanäle").

Extractions: The History of Its Discovery Back to the Index V. Chemical Transmission I n the first decades of the 20th century, research about the chemical mediation of action in the autonomous, or vegetative nervous system, how it was then called, was developing at a feverish pace in many laboratories in the world. The main centers were located in England, where William Maddock Bayliss Ernest Henry Starling After working 12 years on the pharmacology of the Autonomous Nervous System, now in the University of Graz, Austria, he devised the crucial experiment which provided the first reliable evidence for the existence of chemical transmission in a synapse. The legend tells that he had the idea of the experiment in a dream and that he ran to the lab as soon as he was awake.

Extractions: Last month, Bernard Katz, who won the Nobel Prize in 1970 for his work on the synapse, died. Katz was a member of Sydney University in the early 1940's and gave physiology lectures with Eccles and Kuffler. In 1945 he worked in the Madsen building with the group in radiophysics that were laying the foundations of the new discipline of radioastronomy. The International Brain Research Organization asked Professor Max Bennett to write an obituary which appears on their website.

Extractions: The University of Sydney Department of Physiology General Information Research Information for Students Research Opportunities ... General Information The principal aim of the department is to discover the origins of human diseases by furthering knowledge in the fields of biology and medicine, especially as they relate to the nervous system, cardiovascular system and muscular systems. Basic research into the mechanisms by which these systems function is paramount. Such research will allow for improved methods of preventing, diagnosing and treating diseases. The great researchers profiled below laid the foundations for the present efforts of our current academic staff. The Department of Physiology, as a member of the Institute for Biomedical Research , was strongly influenced by the intellectual environment provided by Sir John Eccles, Sir Bernard Katz and Stephen Knuffle. They gave research lectures in the Anderson Stuart Building while working at Sydney Hospital, prior to their winning Nobel Prizes for research into the nervous system. The Department of Physiology was established when Sir Thomas Anderson Stuart took up the Chair of Anatomy and Physiology from 1883 to 1920. He was integral in attracting respected researchers to the department, however most of his energy was spent on establishing the Medical School.

RN Reprinted by permission of Robert Nordlander Part I A Critical Response to Bernard Katz On Our Founding Fathers by Robert Nordlander As published in the January-February 1985 issue of The American Rationalist: The Alternative to Superstition. From Cover. Because of the recent promotion of religion by political means it is important to show what the Founding Fathers of our country had in mind when establishing the beginnings of our democracy. To prevent the European problems of their past they intended to make sure that religious oppression was not dominant in our new nation. Whether they made the wall of separation strong enough is to be proven by the protectors of that wall to ensure a secular government rather than a ruling theocracy as is evident in countries today such as Iran. [Gordon Stein, editor]. The present issue is largely devoted to a subject which has occupied our pages off and on for the past six months. The present article takes the opposite position from the previous ones by Bernard Katz. THIS article marks the end of our treatment of this subject for the forseeable future. Some may think we have devoted far too much space to it already. Perhaps we have, but we feel that the issue is both important and far from settled. While none of our articles will end the controversy, we think that they will show that a case can be made for both sides, perhaps, only by selective quoting from the voluminous writings of the founding fathers..

Extractions: Foto: AP Im Februar 1935 ging der Leipziger Bernard Katz im englischen Hafen Harwich mit vier Pfund Sterling in der Tasche an Land. Dieser Tag sollte künftig sein zweiter Geburtstag sein, er feierte ihn als "Wieder-Geburtstag". Aus Nazi-Deutschland entkommen, sprach der junge Wissenschaftler jüdischer Abstammung am nächsten Morgen im University College London (UCL) bei Professor A.V. Hill, einem der führenden Physiologen der damaligen Zeit, vor. Der Nobelpreisträger empfing den 24jährigen Staatenlosen mit großer Herzlichkeit, für Katz begann ein neues Leben. Obwohl in Leipzig geboren, hatte der Wissenschaftler niemals die deutsche Staatsangehörigkeit besessen. Sein Vater, ein Pelzhändler, hatte Russland 1904 verlassen. Um die Einbürgerung seiner Familie hatte er sich nie bemüht, die Prozedur erschien ihm zu langwierig. "Ich war die ersten sechseinhalb Jahre meines Lebens Untertan des russischen Zaren. Nach dem Ersten Weltkrieg galten wir als "feindliche Ausländer', nach der Oktoberrevolution waren wir plötzlich staatenlos", so Katz. Das Leipziger Schiller-Real-Gymnasium lehnte den Zehnjährigen deshalb ab, obwohl er die Aufnahmeprüfung als einer der Besten seines Jahrgangs bestanden hatte. Jahre später sollte ihm der Status des Staatenlosen zum Vorteil werden: In England galt er nicht als feindlicher Ausländer und bekam 1941 in Australien, wo er seinen Militärdienst absolvierte, seinen ersten Paß.

Extractions: Sir Bernard Katz ' discoveries concerning the mechanism for the release of the transmitter acetylcholine from the nerve terminals at the nerve-muscle junction, under the influence of the nerve impulses, are fundamental not only for the understanding of the so-called cholinergic transmission, but are also of primary importance for our knowledge about the synaptic transmission between the nerve cells in the central nervous system.

Extractions: Sir Bernard Katz, Biophysicist, 1911-2003 Few scientists so influence their colleagues' and students' thinking as to establish an enduring and powerful intellectual principle. Sir Bernard Katz, who has died in London, was one such towering genius, whose work contributed enormously to our understanding of how nerves work and, even more significantly, how nerve cells communicate with one another. He really began his experiments on that problem of neuro-muscular transmission in Sydney after arriving in 1939 to work with (Sir) John Eccles - later a Nobel laureate himself - at the Kanematsu Research Institute at Sydney Hospital. Although he left Australia in 1946, he remained intensely attached to this country. It was here that he worked with Eccles and the young Stephen Kuffler (later professor of neurobiology at Harvard University) - perhaps the world's pre-eminent trio of neuroscientists at the time - and became naturalised in 1941, marrying a Sydney girl, Marguerite Penly. In fact, that naturalisation ended a long and difficult period of statelessness which he had endured since 1917, when he was six. His Russian Jewish family had been expatriates in Germany since the Russo-Japanese war in 1904 and he was born in Leipzig in 1911, where his father was in the fur business.
