The contributions of Ramon y Cajal and other Spanish authors to hypnosis.
2008
The authors review the most important Spanish contributions to hypnosis during the 19th and 20th centuries, with emphasis on the work of Santiago Ramon y Cajal, winner of the 1906 Nobel Prize in medicine. It is widely accepted that he provided a basic foundation for modern neurosciences with his work on neuronal staining and synaptic transmission. What is missing in most accounts of his work is his longstanding interest and work on hypnosis and anomalous phenomena. This article summarizes that lost legacy, discusses other Spanish hypnosis pioneers and gives a brief overview of current hypnosis activities in Spain.
A classification of European skulls from three time periods.
1987
We analyze the taxonomic structure of European populations at three time periods, the Early Middle Ages, the Late Middle Ages and the Recent Period. The data consist of sample means for 10 cranial variables based on 137, 108, and 183 samples for the three periods. Clustering by standard numerical taxonomic procedures reveals that the data are represented only poorly as hierarchic classifications. The clusters form significant and moderately strong associations with an arrangement of the samples by regions (geography) and by language family. Whereas during the early period, language family showed a stronger association with clusters based on cranial morphology, in the recent populations thes…
Straight into the Eyes - Jacek Łumiński and the Silesian Dance Theatre (1991-2011)
2020
The fi nal decade of the 20 th century was the turning-point for the development of Polish contemporary dance. In 1991 Jacek Łuminski established the Silesian Dance Theatre in Bytom. The theatre is said to be in the avant-garde of all activities related to contemporary dance development in Poland. It was J. Łuminski and his theatre who pioneered new trends in contemporary dance at the beginning of the nineties of the 20 th century, at the same time they have conducted educational activity over the intervening twenty years. The aim of this article is to present the artistic and educational activity of the Silesian Dance Theatre of the recent twenty years. In the beginning the author presents…
A brief history of the formation of DNA databases in forensic science within Europe.
2001
The introduction of DNA analysis to forensic science brought with it a number of choices for analysis, not all of which were compatible. As laboratories throughout Europe were eager to use the new technology different systems became routine in different laboratories and consequently, there was no basis for the exchange of results. A period of co-operation then started in which a nucleus of forensic scientists agreed on an uniform system. This collaboration spread to incorporate most of the established forensic science laboratories in Europe and continued through two major changes in the technology. At each step agreement was reached on which systems to use. From the beginning it was realise…
Paleoclimate and bubonic plague: a forewarning of future risk?
2010
Background Human cases of plague (Yersinia pestis) infection originate, ultimately, in the bacterium's wildlife host populations. The epidemiological dynamics of the wildlife reservoir therefore determine the abundance, distribution and evolution of the pathogen, which in turn shape the frequency, distribution and virulence of human cases. Earlier studies have shown clear evidence of climatic forcing on contemporary plague abundance in rodents and humans. Results We find that high-resolution palaeoclimatic indices correlate with plague prevalence and population density in a major plague host species, the great gerbil (Rhombomys opimus), over 1949-1995. Climate-driven models trained on these…
Market empowerment of the patient: the French experience.
2011
Through analysis of the French experience, this article explores the way economic policy has sought to encourage active, well-informed patients by giving them market power. The new status of the patient as consumer is based on two foundations: the endeavour to build a healthcare market and the activation of demand-based policies. The keystone of this new system is a conception of the market as a process constructed by economic policy. Recent measures such as the standardization of care and the introduction of incentives to respect a treatment pathway then constitute effective levers to establish a free-market rationale.
Transmission electron microscopy in molecular structural biology: A historical survey.
2015
In this personal, historic account of macromolecular transmission electron microscopy (TEM), published data from the 1940s through to recent times is surveyed, within the context of the remarkable progress that has been achieved during this time period. The evolution of present day molecular structural biology is described in relation to the associated biological disciplines. The contribution of numerous electron microscope pioneers to the development of the subject is discussed. The principal techniques for TEM specimen preparation, thin sectioning, metal shadowing, negative staining and plunge-freezing (vitrification) of thin aqueous samples are described, with a selection of published im…
Transitions démocratiques et transformation des élites en Allemagne au XXe siècle
2014
Les articles réunis dans ce dossier sont issus d’une journée d’étude qui a réuni le 7 juin 2013 à l’université de Bourgogne germanistes civilisationnistes et historiens français, allemands et italiens autour du thème « Transitions démocratiques et transformation des élites en Allemagne au XXe siècle ». Le choix de ce cette problématique par ailleurs très actuelle – que l’on pense par exemple au printemps arabe et à ses conséquences – découle d’un double constat paradoxal : d’une part, l’Allemagne a été directement concernée par les trois « vagues de démocratisation » du XXe siècle: celle consécutive à la Première guerre mondiale, qui a conduit à la naissance de la République de Weimar, cell…
Mouse models for multiple sclerosis: historical facts and future implications.
2011
AbstractMultiple sclerosis (MS) is an inflammatory and demyelinating condition of the CNS, characterized by perivascular infiltrates composed largely of T lymphocytes and macrophages. Although the precise cause remains unknown, numerous avenues of research support the hypothesis that autoimmune mechanisms play a major role in the development of the disease. Pathologically similar lesions to those seen in MS can be induced in laboratory rodents by immunization with CNS-derived antigens. This form of disease induction, broadly termed experimental autoimmune encephalomyelitis, is frequently the starting point in MS research with respect to studying pathogenesis and creating novel treatments. M…
