Streptomycin: discovery and resultant controversy 总被引:1,自引:0,他引:1
M Wainwright 《History and philosophy of the life sciences》1991,13(1):97-124
The antibiotic streptomycin was discovered soon after penicillin was introduced into medicine. Selman Waksman, who was awarded the Nobel Prize for the discovery, has since generally been credited as streptomycin's sole discoverer. However, one of Waksman's graduate students, Albert Schatz, was legally recognized as streptomycin's co-discoverer and received a share of the royalties from the drug. The aim of this essay is to discuss the streptomycin story, largely using previously unquoted archival material, and in particular to provide further evidence for the important role which Schatz played in the discovery. 相似文献

The discovery of streptomycin is attributed to a microbiologist, Selman Waksman, Nobel Prize 1952, a paternity that was disputed by his collaborator Albert Schatz, who was the first author of the princeps article. Two pioneering clinical studies involved streptomycin, both of which have been widely used as reference works. The first one was English, under the name of Austin Bradford Hill. It inaugurated a randomization in medicine. The second trial was American, and carried out by the Veteran Administration. It made use for the first time of the "control group". The present article analyses the genesis of clinical trials and illustrates the recurrent difficulties encountered in their implementation. 相似文献

Christian de Duve is considered to be one of the founding fathers of autophagy. After all, he coined the term, and he played an instrumental role in the discovery of the lysosome, for which he received the Nobel Prize. There is no question that de Duve is a stellar scientist, but who was the person in the trenches, doing the actual laboratory work in the lab that led to the initial papers on autophagy? Dr. Russell L. Deter wrote the first papers from the de Duve lab that deal with this topic. To get some insight into the origins of this field, I interviewed Dr. Deter, as detailed in this perspective. 相似文献

Sulston J 《The Yale journal of biology and medicine》2002,75(5-6):299-306
Sir John Sulston was a co-winner of the Nobel Prize for Medicine in 2002. He won the prize for his discoveries concerning "genetic regulation of organ development and programmed cell death," along with his colleagues sydney Brenner and H. Robert Horvitz. Dr. Sulston was founding director of the Sanger Centre, Cambridge, England, which he headed from 1992 to 2000. From 1993 to 2000, he led the British arm of the international team selected to work on the Human Genome Project. He is co-author of the book The Common Thread: A Story of Science, Politics, Ethics, and the Human Genome, published by Joseph Henry Press in 2002.This interview was conducted on December 20, 2002, shortly after Dr. Sulston was awarded his Nobel Prize and was originally broadcast on that date on radio station WPKN-FM in Bridgeport, Connecticut. The interview was conducted by Valerie Richardson, the Managing Editor of The Yale Journal of Biology and Medicine.Dr. Sulston has been an outspoken advocate against letting the data from the Human Genome Project become property of commercial interests that would charge the world's scientific community for its use. Since leaving the Sanger Institute, he has worked with OxFam, the Oxford Campaign for Famine Relief. 相似文献

The Nobel Prize in Physiology or Medicine 2015 was awarded for discoveries related to the control of parasitic diseases using natural products of microbial and plant origin. In current drug discovery programs, synthesized compounds are widely used as a screening source; however, this award reminds us of the importance of natural products. Here, we introduce our phenotypic screening methods based on changes in cell morphology and discuss their effectiveness and impact for natural products in drug discovery. 相似文献

The ubiquitin-proteasome system 总被引:10,自引:0,他引:10
The 2004 Nobel Prize in chemistry for the discovery of protein ubiquitination has led to the recognition of cellular proteolysis
as a central area of research in biology. Eukaryotic proteins targeted for degradation by this pathway are first ‘tagged’
by multimers of a protein known as ubiquitin and are later proteolyzed by a giant enzyme known as the proteasome. This article
recounts the key observations that led to the discovery of ubiquitin-proteasome system (UPS). In addition, different aspects
of proteasome biology are highlighted. Finally, some key roles of the UPS in different areas of biology and the use of inhibitors
of this pathway as possible drug targets are discussed. 相似文献

Zuckerkandl E 《Journal of molecular evolution》2012,74(5-6):233-236
In 1962, a young post-doctoral fellow and a prominent Nobel Prize winner, Emile Zuckerkandl and Linus Pauling, published a seminal paper that described the relationship between the average number of aminoacid replacements and divergence time, known as the molecular clock (Zuckerkandl and Pauling 1962). Fifty years after the original publication, I was fortunate enough to interview Emile Zuckerkandl. We shared thoughts on his life and the historical events that led to the discovery of the molecular clock. 相似文献

Background
Conventional scientometric predictors of research performance such as the number of papers, citations, and papers in the top 1% of highly cited papers cannot be validated in terms of the number of Nobel Prize achievements across countries and institutions. The purpose of this paper is to find a bibliometric indicator that correlates with the number of Nobel Prize achievements.Methodology/Principal Findings
This study assumes that the high-citation tail of citation distribution holds most of the information about high scientific performance. Here I propose the x-index, which is calculated from the number of national articles in the top 1% and 0.1% of highly cited papers and has a subtractive term to discount highly cited papers that are not scientific breakthroughs. The x-index, the number of Nobel Prize achievements, and the number of national articles in Nature or Science are highly correlated. The high correlations among these independent parameters demonstrate that they are good measures of high scientific performance because scientific excellence is their only common characteristic. However, the x-index has superior features as compared to the other two parameters. Nobel Prize achievements are low frequency events and their number is an imprecise indicator, which in addition is zero in most institutions; the evaluation of research making use of the number of publications in prestigious journals is not advised.Conclusion
The x-index is a simple and precise indicator for high research performance. 相似文献13.

The Human Genome Project (HGP) is regarded by many as one of the major scientific achievements in recent science history, a large-scale endeavour that is changing the way in which biomedical research is done and expected, moreover, to yield considerable benefit for society. Thus, since the completion of the human genome sequencing effort, a debate has emerged over the question whether this effort merits to be awarded a Nobel Prize and if so, who should be the one(s) to receive it, as (according to current procedures) no more than three individuals can be selected. In this article, the HGP is taken as a case study to consider the ethical question to what extent it is still possible, in an era of big science, of large-scale consortia and global team work, to acknowledge and reward individual contributions to important breakthroughs in biomedical fields. Is it still viable to single out individuals for their decisive contributions in order to reward them in a fair and convincing way? Whereas the concept of the Nobel prize as such seems to reflect an archetypical view of scientists as solitary researchers who, at a certain point in their careers, make their one decisive discovery, this vision has proven to be problematic from the very outset. Already during the first decade of the Nobel era, Ivan Pavlov was denied the Prize several times before finally receiving it, on the basis of the argument that he had been active as a research manager (a designer and supervisor of research projects) rather than as a researcher himself. The question then is whether, in the case of the HGP, a research effort that involved the contributions of hundreds or even thousands of researchers worldwide, it is still possible to “individualise” the Prize? The “HGP Nobel Prize problem” is regarded as an exemplary issue in current research ethics, highlighting a number of quandaries and trends involved in contemporary life science research practices more broadly. 相似文献

An Ottawa team is in a fierce race to produce an artificial heart. If it wins, the prize will be huge: a worldwide market worth billions of dollars. The team, led by Dr. Tofy Mussivand, brings together scientists and entrepreneurs. The goal is to produce a heart that improves patients'' quality of life and doesn''t leave them tethered to a machine in hospital. Current plans are to complete clinical tests by 2000 and to have a commercial product ready for market in 2001-2. Several other groups are also racing the clock. 相似文献

With the decision to award the Nobel Prize in Physiology or Medicine to Drs. S. ōmura, W.C. Campbell, and Y. Tu, the importance and usefulness of natural drug discovery and development have been revalidated. Since the end of the twentieth century, many genome analyses of organisms have been conducted, and accordingly, numerous microbial genomes have been decoded. In particular, genomic studies of actinomycetes, micro-organisms that readily produce natural products, led to the discovery of biosynthetic gene clusters responsible for producing natural products. New explorations for natural products through a comprehensive approach combining genomic information with conventional methods show great promise for the discovery of new natural products and even systematic generation of unnaturally occurring compounds. 相似文献

The year 2010 is the centennial of the publication of the "Seven Little Devils" in the predecessor of Acta Physiologica. In these seven papers, August and Marie Krogh sought to refute Christian Bohr's theory that oxygen diffusion from the lungs to the circulation is not entirely passive but rather facilitated by a specific cellular activity substitute to secretion. The subjects of the present reevaluation of this controversy are Christian Bohr, Professor and Doctor of Medicine (1855-1911), nominated three times for the Nobel Prize; August Krogh, Doctor of Philosophy (1874-1949), Christian Bohr's assistant and later Nobel Prize laureate (1920); and Marie Krogh, née J?rgensen, Doctor of Medicine and wife of August Krogh (1874-1943). The controversy concerned is the transport of oxygen from the lungs into the bloodstream: are passive transport and diffusion capacity together sufficient to secure the oxygen supply in all circumstances or is there an additional specific ("energy consuming" or "active") mechanism responsible for the transport of oxygen from the alveoli into the bloodstream? The present discussion purports to show that the contestants' views were closer than the parties themselves and posterity recognized. Posterity has judged the dispute unilaterally from the Nobel laureate's point of view, but it is evident that August Krogh's Nobel Prize was awarded for the discovery of a cellular activity (Christian Bohr's expression), represented by Krogh's discovery of capillary recruitment. Christian Bohr appears to have been correct in the narrower sense that the diffusion capacity at rest is not great enough to explain the transport during work; a special mechanism intervenes and optimizes the conditions under which diffusion acts. August Krogh, of course, was right in the wider sense that the transport mechanism itself is always entirely passive. 相似文献
