Therapeutic practice with stem cells even if not yet realistic has open a cautious optimism among scientists. The mechanism controlling cell differentiation into cell types are not known in details yet. Exists real danger to influence wrongly the public opinion.

In the future, the Human Genome Project could eventually open the way to perhaps the determination of the complete wiling diagram of the human brain. This kind of progress may move neuroscience forward into the next level of understanding of human neurophysiology, development and behavior. The next crucial step would be to know, exactly what are the function of this genes, and why its lack or alteration causes a certain disease. Although, genomic has in some way contributed to almost every (...) aspects of neurobiology, the results are both significant and troubling.One of the areas, where HGP will contribute to neuroscience is the mapping of qualitative or complex traits. Complex traits like appearence, intelligence and personality are likely to be affected by hundreds or thousands of different genes, rather than one or a few. On the other hand, the complex organisms are not just the simple result of the sum of their genes, nor do genes alone build the different part of organism or influence behaviour by themselves. In spite of the wide variety of misunderstanding, misinterpretation or possible misusing of these new genetic information, this sort of research may eventually lead to useful practical medical results for humans. This information can contribute to work out therapies to treat learning and memory disorders, neurological disorders like Alzheimer's disease, afflicting more and more people in an increasingly ageing population. Genetics believe, there are 3000 to 4000 hereditary diseases. Gene therapy could one day cure some of them, but only when all the details of their genetic basis are known. Biomedicine in the next century will probably have a completely new role in society based on the beginnings inherent in the HGP.There is a general agreement, that modern neuroscience raises important ethical concerns that not have been adequately addressed either by scientists themselves or by the bioethics community. Some scientists interpreted the rapid progress in neuroscience as additional conformation for a materialist account of human nature, resulting in an attack on traditional belief systems. There is a clear tension between the widely held believes and the intellectual views of many scientists. (shrink)

A Nobel Prize winner, Dr. Szent-Györgyi concerns himself with the underlying forces and conditions that have prevented the realization of the higher possibilities of the American Dream, and, by extension, of all mankind. He addresses himself especially to the youth of the world in his attempt to show how man, the more he progresses technologically, seems the more to regress psychologically and socially, until he resembles his primate ancestors in a state of high schizophrenia. The fundamental question asked by this (...) book is: Why is it that most of the scientific research that is done to elevate human life serves in the end to destroy it? That this phenomenon exists is unarguable. How to alter it is the problem the author tackles. He finds the possibility, indeed the instrument of our survival, in our youth. Dr. Szent-Györgyi calls upon youth the world over to organize and exercise their power to create a new world. He implores them not to waste their energies in petulance and frustration-the world is ripe for the radical changes needed for man's survival, and for youth to fritter away their opportunity would be to compound the tragedy and seal the fate of mankind. Born into the fourth generation of a noted family of scientists in Hungary, Albert Szent-Györgyi decided at an early age to devote his life to biological research. As a medical student he required international recognition for his studies in microscopic anatomy. The First World War, which he spent in the service of the Austro-Hungarian army, caused a break in his career. After the war he left his devastated country to work for ten years in various countries, notably Germany, Holland, England and the United States. He then returned to his native Hungary to help rebuild science there. In 1937, he won the Nobel Prize for his studies on metabolism and for the discovery of ascorbic acid (Vitamin C). He soon found himself in conflict with the growing movement of Nazism, was arrested, escaped, and was hunted for years by the secret service of Hitler. After World War II, disappointed by Soviet colonialism and the terrorist methods of Stalin, he left Hungary and found refuge at the Marine Biological Laboratory of Woods Hole, Massachusetts.

Dementia accompanies aging in certain susceptible individuals. The chemical function of the brain remains normal, but certain neurotransmitter-selective diseases, such as Parkinson's disease, Huntington's disease, and Alzheimer's disease occur more commonly with age.There are at least two issues troubling researchers of senile dementia at the moment. One is the contribution of cell death, as opposed to selective neuronal atrophy, to the pathology of degenerative disorders. The other is how early the onset of dementia might be detected. The resolution of such (...) issues is important for the design of therapies for the common and most serious chronic, rather than acute, neurodegenerative disease.Alzheimer's disease is one of the most devastating neurological disorders. The ethical debate is often related to when human biological life ceases or when a person ceases to exist. If the elder is still a person, he/she is no more the same person. Huntington's disease is inherited as a highly penetrant, autosomal dominant neuronal disorder. A genetic test can accurately predict a person's risk and that of the children. As the knowledge of the genetic basis is increasing and prenatal diagnosis gets easier, the possibilities to avoid child disorders will become greater, but genetic testing raises problematic ethical issues. Ethical action involves the right to know and the right not to know, it involves freedom of choice and freedom implies knowledge. It is ethical that relatives in age of procreation should be informed. In any case, efficacy and safety of the procedure, the risk-benefit ratio for a particular disease must be judged to be acceptable and understood through informed consent by the patient or the family or both.

The new methods of modern sciences can contribute to understand the genesis of mental illness, the disturbances in brain chemistry, physiology, anatomy or genetical information underlying different diseases of the nervous system. Understanding mental illness is not only challenging to science, but is also of great social importance. Moreover, the new developments of neurosciences put new lights on discussions such as brain-mind concepts, unity of mind, definition of consciousness and even definition of the person.For the majority of the scientists, it (...) is clear today that the mind can not be conceived any more as unique and indivisible. For philosophers, it is clear also that neuroscience influenced their vision of life and death: neurosciences are not strange to the debate whole-body death versus whole-brain death for instance. Modern scientific achievements have expanded our vision, allowing us to percieve previously unanticipated interrelationships between biological and psychological phenomena. The boundary between some behavioural and higher neural function studies and biology is arbitrary and changing. It has been imposed not by the natural contours of the disciplines, but by lack of knowledge. (shrink)

Albert (von) Szent-Györgyi started his studies on biological oxidation processes - which also resulted in the discovery of vitamin C, for which he received the Nobel Price in 1937 - in the Laboratory of Physiology of the University in Groningen in 1922-1926. These studies were later continued in Cambridge (UK) and Szeged (Hungary). When he had already received the invitation as well as the financial means to come and work in Cambridge, he still did experiments in Groningen to find out (...) whether the adrenal extract, isolated by him and later found to be a major source of vitamin C, contained the hormone essential for the survival of cats whose adrenals were removed. He was rather upset by the negative results of this experiment, judging by the recollections of a former student of his. This history constitutes an interesting example of the difference between serendipitous discovery and planned invention. (shrink)

‘Woman questions’ were emphasized in common speech during the time of the party-state in Hungary. In the 1950s this was symbolized by women tractor drivers, Stakhanovites in construction industry, or women who were present in public life and in politics. Mrs Mihály Berki, née Magdolna Szakács was one of the first emblematic female politicians who was appointed the first peasant woman főispán [honorary prefect] from a village at the end of 1948. The central elements of her life story were (...) the social and geographical mobility: how could she adapt to the new roles and environments? What kind of competences did she need? How did she acquire them? Did the image of a peasant woman politician with a kerchief change during her career? I intend to outline a wider social context in connection with the determining features of her career such as her being a female, her peasant background and her institutional socialization. (shrink)

This paper discusses the chemistry manuscript collection in an institution that does not readily come to mind when searching for unpublished matter on the history of chemistry, the National Library of Medicine in Bethesda, Maryland. This collection includes personal papers of some twentieth-century American chemists and biochemists, lecture notes of British and American chemistry courses of the eighteenth, nineteenth, and twentieth centuries from a variety of institutional settings, and extended oral histories of some major figures in the history of modern (...) chemistry and biochemistry. Among those represented in this collection are Joseph Black, Louis Pasteur, George B. Wood, Donald D. Van Slyke, and Albert Szent-Györgyi. In addition to illustrating the type of resources available, this paper also suggests some specific ways in which the collection can contribute to research in the history of chemistry. (shrink)
