Three overlooked photosynthesis papers of Otto Warburg (1883-1970), published in the 1940s in German and in Russian, on light-driven water oxidation coupled to benzoquinone reduction.

After a brief background on Otto Heinrich Warburg (1883-1970), and some of his selected research, we provide highlights, in English, of three of his papers in the 1940s-unknown to many as they were not originally published in English. They are: two brief reports on Photosynthesis, with Wilhelm Lüttgens, originally published in German, in 1944: 'Experiment on assimilation of carbonic acid'; and 'Further experiments on carbon dioxide assimilation'. This is followed by a regular paper, originally published in Russian, in 1946: 'The photochemical reduction of quinone in green granules'. Since the 1944 reports discussed here are very short, their translations are included in the Appendix, but that of the 1946 paper is provided in the Supplementary Material. In all three reports, Warburg provides the first evidence for and elaborates on light-driven water oxidation coupled to reduction of added benzoquinone. These largely overlooked studies of Warburg are in stark contrast to Warburg's well-known error in assigning the origin of the photosynthetically formed dioxygen to carbonate.

Introducción de resultados científicos: bases teórico-metodológicas para su mejora en la educación médica / Introduction of scientific results: theoretic-methodological bases for its improvement in medical education

RESUMEN En Cuba, la transformación de la realidad por medio de la introducción de resultados científicos -en aras del desarrollo sostenible-, es una alta prioridad por parte de las primeras instancias de dirección desde 1959. La introducción de resultados investigativos ha sido abordada por prestigiosos autores desde diferentes aristas y contextos, pero existen escasas referencias relacionadas con el tema en el ámbito de las ciencias de la educación médica. En consecuencia, este artículo presenta un análisis sobre las tendencias del proceso de introducción de resultados científicos en el ámbito académico, para luego delinear cuáles pudieran ser las bases teórico-metodológicas para la mejora del proceso en el ámbito de la educación médica (AU).

ABSTRACT In Cuba, the transformation of reality through the introduction of scientific results -for the sake of the sustainable development- is a high priority for the first instances of direction since 1959. The introduction of research results has been approached by prestigious authors from different edges and in different contexts, but there are few references related to the theme in the field of the medical education sciences. Consequently, this article presents an analysis on the tendencies of the process of introducing scientific results in the academic sphere, and then outlines the possible theoretic-methodological bases for improving the process in the field of medical education (AU).

My precarious career in photosynthesis: a roller-coaster journey into the fascinating world of chloroplast ultrastructure, composition, function and dysfunction.

Despite my humble beginnings in rural China, I had the good fortune of advancing my career and joining an international community of photosynthesis researchers to work on the 'light reactions' that are a fundamental process in Nature. Along with supervisors, mentors, colleagues, students and lab assistants, I worked on ionic redistributions across the photosynthetic membrane in response to illumination, photophosphorylation, forces that regulate the stacking of photosynthetic membranes, the composition of components of the photosynthetic apparatus during acclimation to the light environment, and the failure of the photosynthetic machinery to acclimate to too much light or even to cope with moderate light due to inevitable photodamage. These fascinating underlying mechanisms were investigated in vitro and in vivo. My career path, with its ups and downs, was never secure, but the reward of knowing a little more of the secret of Nature offset the job uncertainty.

Uncovering the metaphysics of psychological warfare: The social science behind the Psychological Strategy Board's operations planning, 1951-1953.

In April 1951 president Harry S. Truman established the Psychological Strategy Board to enhance and streamline America's sprawling psychological warfare campaign against the USSR. As soon as the Board's staff began work on improving US psychological operations, they wondered how social science might help them achieve their task. Board Director, Gordon Gray, asked physicist turned research administrator Henry Loomis to do a full review of America's social science research program in support of psychological operations. Loomis willingly accepted the task. This paper documents Loomis's investigation into America's social science research program. It uncovers the critical role that government departments had in the creation of research in the early 1950s and thus highlights that the government official is an important actor in the history of social science and the application of social science to psychological operations at the beginning of the Cold War.

Historical, descriptive and exploratory analysis of application of bibliometrics in nursing research.

OBJECTIVE: The aim of the study was to analyse the literature production on application of bibliometrics in nursing research. METHODS: Historical, descriptive, and exploratory bibliometrics analyses were used. The papers were harvested from the Scopus bibliographical database (Elsevier, Maribor, Netherlands), on November 18th, 2018, using the search string bibliometric* in publication titles, abstracts, and keywords, limited to the subject of nursing, for the period 1970 to 2018. FINDINGS: The search resulted in 531 publications with 18 publications removed after manual inspection of publications abstracts. The literature production trend was positive. The nursing specific historical roots appeared only recently. The United States of America and Spain were the most productive countries, and most papers were published in Nutricion Hospitalaria and the Journal of Advanced Nursing. Descriptive analysis, research evaluation, content analysis, citation analyses, and trend analysis in nursing research were the most prolific themes. CONCLUSIONS: Applications of bibliometric in nursing is comparable to bibliometrics use in general, however there are some gaps including the use of altmetrics and of Big Data analysis.

The 'Poitrot Report', 1945: the first public document on Nazi euthanasia.

The aim of this paper is to shed light on the so-called 'Poitrot Report', submitted to the French Military Government in Baden-Baden, Germany, in December 1945 and published in a reduced German version in 1946. Its author was the French-Moroccan psychiatrist Robert Poitrot, who had been put in charge of the public mental asylums in Südwürttemberg after World War II. Poitrot took responsibility for restoring psychiatric care during the occupation, and was also eager to document Nazi 'euthanasia' and to start investigating the role of staff in mental hospitals during National Socialism. Focusing on the 'Poitrot Report', this paper also reflects on life in Württemberg mental hospitals and the interaction between French representatives such as Poitrot and regional German medical staff.

Leo Kanner's Mention of 1938 in His Report on Autism Refers to His First Patient.

Leo Kanner begins his landmark 1943 case series on autistic children by stating the condition was first brought to his attention in 1938. Recent letters to JADD have described this reference as "mysterious" and speculated it refers to papers published that year by Despert or Asperger. In fact, as Kanner goes on to state, 1938 is when he examined the first child in his case series. An exchange of letters with Despert and later writing by Kanner also point to the originality of his observations.

[Hans Selye, the grandmaster of creativity and originality]. / Selye János, a kreativitás és eredetiség nagymestere.

Hans Selye, the father of the stress concept, was a giant of science of the twentieth century. Beyond his best-known work on stress, he also made several discoveries on various other fields of experimental medicine. He described and characterized various pluricausal diseases. In addition, he made pivotal contributions to the broad field of endocrinology, especially to the classification of steroids and to our better understanding of their mode of action. He developed surgical technics and experimental animal models suitable for studying the pathogenesis and prevention of human diseases. Selye was an extremely well educated, highly intelligent and disciplined individual, an original and creative scientist, an outstanding teacher, a philosopher, a prolific author, a fabulous communicator and a gifted organizer successfully establishing, developing and managing a major academic research institution, the word-famous Institute of Experimental Medicine and Surgery of the University of Montreal.

[A peculiar man - about Hans Selye, as reflected in his Hungarian connections]. / Egy "furcsa ember" - Selye Jánosról magyar kapcsolatainak tükrében.

Hans Selye made a great impact on the Hungarian medical, scientific and public life. His first Hungarian publication about the alarm-reaction appeared 1938 in the Orvosi Hetilap. His Hungarian relationship was quite extensive after the war as he published, gave lectures, and accepted Hungarian students for specialized training in his Canadian institute saw. The rich documents in archives about Selye are currently being processed and those will surely shed light on Selye's life in further details.
