    To analyze the neurological work of Artur Galcerán i Granés (Girona 1850-Barcelona 1919) founder of the Society of Psychiatry and Neurology of Barcelona in 1911. We performed a literature search using MEDLINE from the keywords"Galceran Granés" and "Society of Psychiatry and Neurology of Barcelona", using the doctoral thesis of M. G. Fabregas Camps: "History of Neurology in Catalonia. From 1882 to 1949 ", and original historical bibliographical sources of the Library of the Academy of Sciences Mèdiques de Catalunya i Balears. Artur Galcerán i Granés was a disciple of the school of psychiatry of Dr. Joan Giné i Partagàs. His highlighting neurological work was: 1) "Some static and dynamic inferences about the brain, which may serve to clarify the concept of localization", 2) "Treatment of epilepsy" and 3) "Neuropathology and General Psychiatry". He was editor of "Archivos de Terapeútica de las enfermedades nerviosas y mentales" and "Anales de la Sociedad de Psiquiatría y Neurología". He was director of the mental asylum in Sant Boi of Llobregat and Pere Mata of Reus. In 1911 he founded the first Catalan and Spanish neurological society in Barcelona. The neurological work of Artur Galcerán i Granes is remarkable and significant. He was the founder of the first Catalan and Spanish neurological society: The Society of Psychiatry and Neurology of Barcelona in 1911, the forerunner of the Catalan Society of Neurology.

    Jaak Panksepp, known best for his work on animal emotions and coining the term "affective neuroscience," investigates the primary processes of brain and mind that enable and drive emotion. As an undergraduate, he briefly considered a career in electrical engineering but turned instead to psychology, which led to a 1969 University of…

    Artur Wołyński (1844-1893) was, undoubtedly, one of the most interesting personages of Polish émigrés after January Uprising. He belonged to these circles of Polish émigrés, who were able to reconcile their patriotic aspirations with realities and interest of the countries that entertained them. As far as Wołyński is concerned, it found its expression in the efforts that were made in order to assimilate two nations--Polish and Italian people--appealing to the common history and familiar cultural traditions. An important element of integrating all the above-discussed actions was his scientific activity. The mentioned activity included, first of all, his studies on Nicolaus Copernicus and Galileo Galilei. In the article were analyzed more comprehensive scientific descriptions dedicated to Copernicus and Galileo prepared by Wołyński, and their significance and opinions on them of the learned, whose works treated on Copernicus and Galileo as well. Secondly, in the field of scientific activity of Wołyńiski, one can also observe his researches and the process of elaborating sources for Polish and Italian his tory, particularly concerning the 17th century. However, most of his attention Wołyński paid to collecting and working out the materials concerning January Uprising. Speaking a modern language, one can say that Wołyński in a way polled the insurgents of January Uprising sending to them an appropriate list of questions, additionally allowing for their biographies. In the paper was also included a detailed description of this broad initiative together with its results. Up till now, not much attention has been paid to this significant scientific activity and its contexts. So, the present article is to remind of meritorious personage of Wołyński, and particularly of his output within the realm of history of science, history of Polish and Italian relationships, and of the role he played in bequeathing memory of January Uprising.

    The cave of Toca do Serrote do Artur (São Raimundo Nonato Archaeological Area, southeastern Piauí, Brazil) has yielded a Mammalian community constituted of Dasypus septemcinctus, Propraopus cf. sulcatus, Hoplophorus euphractus, Glyptodon clavipes, Conepatus sp., Panthera onca, Equus neogaeus, Dicotyles tajacu, Tayassu pecari, Palaeolama major, Mazama guazoubira, Mazama americana and a large Cervid. In comparison with the Mammalian fauna of the other sites from the same area, such a list shows a comparatively reduced biodiversity together with the presence of rare ( Hoplophorus, Conepatus) or unknown ( Propraopus, Palaeolama major) taxa. Explanation lies in the more recent age of the fossiliferous layers, probably Lower Holocene, as demonstrated by two 14C dating of 8 490 ± 120 BP and 6 890 ± 60 BP of the highest one. Moreover, that fauna shows the late survival of some genera ( Propraopus, Hoplophorus, Glyptodon, Equus, Palaeolama) together with climatic modifications related to the Pleistocene-Holocene transition.

    Motivation: Increased availability of various genotyping techniques has initiated a race for finding genetic markers that can be used in diagnostics and personalized medicine. Although many genetic risk factors are known, key causes of common diseases with complex heritage patterns are still unknown. Identification of such complex traits requires a targeted study over a large collection of data. Ideally, such studies bring together data from many biobanks. However, data aggregation on such a large scale raises many privacy issues. Results: We show how to conduct such studies without violating privacy of individual donors and without leaking the data to third parties. The presented solution has provable security guarantees.

    2013-01-01

    Summary This paper elucidates the origins of scientific work on stem cells. From the late nineteenth century onwards, the notion of stem cells became customary in scientific communities of Imperial Germany. Adopting the term ‘Stammzelle’ from Ernst Haeckel, Theodor Boveri was influential in introducing the concept in embryological studies and early genetics around 1900, describing a capacity of stem cells for self-renewal as well as differentiation. Blood stem cells were at the same time conceptualized by histologists such as Ernst Neumann and Artur Pappenheim in studies of physiological haematopoiesis and various forms of leukaemia. Furthermore, building on Julius Cohnheim’s theory that tumours arise from ‘embryonic remnants’ in the adult body, pathologists aimed at identifying the cells of origin, particularly in the embryo-like teratomas. Embryonic stem cells thus assumed an ambiguous status, partly representing common heritage and normal development, partly being seen as potential causes of cancer if they had been left behind or displaced during ontogeny. In the 1950s and 1960s experimental research on teratocarcinomas by Leroy Stevens and Barry Pierce in the USA brought the strands of embryological and pathological work together. Alongside the work of Ernest McCulloch and James Till at the Ontario Cancer Institute, from the early 1960s, on stem cells in haematopoiesis, this led into the beginnings of modern stem cell research.

    Abstract Artur, S, Bogdan, P, Kawczyński, A, Winiarski, S, Grzegorz, J, and Andrzej, R. Manifestations of proprioception during vertical jumps to specific heights. J Strength Cond Res 31(6): 1694–1701, 2017—Jumping and proprioception are important abilities in many sports. The efficiency of the proprioceptive system is indirectly related to jumps performed at specified heights. Therefore, this study recorded the ability of young athletes who play team sports to jump to a specific height compared with their maximum ability. A total of 154 male (age: 14.8 ± 0.9 years, body height: 181.8 ± 8.9 cm, body weight: 69.8 ± 11.8 kg, training experience: 3.8 ± 1.7 years) and 151 female (age: 14.1 ± 0.8 years, body height: 170.5 ± 6.5 cm, body weight: 60.3 ± 9.4 kg, training experience: 3.7 ± 1.4 years) team games players were recruited for this study. Each participant performed 2 countermovement jumps with arm swing to 25, 50, 75, and 100% of the maximum height. Measurements were performed using a force plate. Jump height and its accuracy with respect to a specified height were calculated. The results revealed no significant differences in jump height and its accuracy to the specified heights between the groups (stratified by age, sex, and sport). Individuals with a higher jumping accuracy also exhibited greater maximum jump heights. Jumps to 25% of the maximum height were approximately 2 times higher than the target height. The decreased jump accuracy to a specific height when attempting to jump to lower heights should be reduced with training, particularly among athletes who play team sports. These findings provide useful information regarding the proprioceptive system for team sport coaches and may shape guidelines for training routines by working with submaximal loads. PMID:28538322

    Little is known about the first Catalan neurological societies. Our aim was to analyse them from the formation of the pioneering Society of Psychiatry and Neurology of Barcelona founded in 1911. We performed a literature search using MEDLINE using the key words: neurological societies, using the doctoral thesis of MG Fabregas: «History of Neurology in Catalonia: from 1882 to 1949» and original historical bibliographical sources of the Library of the Academy of Sciences Mèdiques de Catalunya i Balears. The presence of neurological societies in Catalunya is relatively recent. The first society was established a century ago, and was the Society of Psychiatry and Neurology of Barcelona, founded by Artur Galcerán i Granés in 1911. This became the Catalan Society of Neurology and Psychiatry in 1934 under the presidency of Belarmino Rodriguez Arias. With the civil war, the society broke up and reappeared under the name Association of Psychiatry and Neurology presided over by José Córdoba Rodríguez (1941), emerging in 1968 as the Association of Neurological Sciences with Lluís Barraquer Bordas as President. In 1973 it assumed the current name of Catalan Society of Neurology under Agustí Codina Puiggrós. The Society of Psychiatry and Neurology of Barcelona founded in 1911 by Galcerán i Granés was the first neurological society and was a precursor of the Catalan Society of Neurology. It should be highlighted that in 2011 it will be 100 years since the founding of the first neurological society in Catalonia and Spain. Copyright © 2011 Sociedad Española de Neurología.

  4. Twenty Seven Years of Quantum Cryptography!

    NASA Astrophysics Data System (ADS)

    Hughes, Richard

    2011-03-01

    One of the fundamental goals of cryptographic research is to minimize the assumptions underlying the protocols that enable secure communications between pairs or groups of users. In 1984, building on earlier research by Stephen Wiesner, Charles Bennett and Gilles Brassard showed how quantum physics could be harnessed to provide information-theoretic security for protocols such as the distribution of cryptographic keys, which enables two parties to secure their conventional communications. Bennett and Brassard and colleagues performed a proof-of-principle quantum key distribution (QKD) experiment with single-photon quantum state transmission over a 32-cm air path in 1991. This seminal experiment led other researchers to explore QKD in optical fibers and over line-of-sight outdoor atmospheric paths (``free-space''), resulting in dramatic increases in range, bit rate and security. These advances have been enabled by improvements in sources and single-photon detectors. Also in 1991 Artur Ekert showed how the security of QKD could be related to quantum entanglement. This insight led to a deeper understanding and proof of QKD security with practical sources and detectors in the presence of transmission loss and channel noise. Today, QKD has been implemented over ranges much greater than 100km in both fiber and free-space, multi-node network testbeds have been demonstrated, and satellite-based QKD is under study in several countries. ``Quantum hacking'' researchers have shown the importance of extending security considerations to the classical devices that produce and detect the photon quantum states. New quantum cryptographic protocols such as secure identification have been proposed, and others such as quantum secret splitting have been demonstrated. It is now possible to envision quantum cryptography providing a more secure alternative to present-day cryptographic methods for many secure communications functions. My talk will survey these remarkable developments.

  5. What affective neuroscience means for science of consciousness.

    PubMed

    Almada, Leonardo Ferreira; Pereira, Alfredo; Carrara-Augustenborg, Claudia

    2013-01-01

    The field of affective neuroscience has emerged from the efforts of Jaak Panksepp in the 1990s and reinforced by the work of, among others, Joseph LeDoux in the 2000s. It is based on the ideas that affective processes are supported by brain structures that appeared earlier in the phylogenetic scale (as the periaqueductal gray area), they run in parallel with cognitive processes, and can influence behaviour independently of cognitive judgements. This kind of approach contrasts with the hegemonic concept of conscious processing in cognitive neurosciences, which is based on the identification of brain circuits responsible for the processing of (cognitive) representations. Within cognitive neurosciences, the frontal lobes are assigned the role of coordinators in maintaining affective states and their emotional expressions under cognitive control. An intermediary view is the Damasio-Bechara Somatic Marker model, which puts cognition under partial somatic-affective control. We present here our efforts to make a synthesis of these views, by proposing the existence of two interacting brain circuits; the first one in charge of cognitive processes and the second mediating feelings about cognitive contents. The coupling of the two circuits promotes an endogenous feedback that supports conscious processes. Within this framework, we present the defence that detailed study of both affective and cognitive processes, their interactions, as well of their respective brain networks, is necessary for a science of consciousness.

    Watt, Douglas F

    2005-03-01

    Jaak Panksepp's article 'Affective Consciousness: Core Emotional Feelings in Animals and Humans' is a excellent review and summary by a leading empirical contributor whose work for many years has been running counter to reigning behavioristic premises in neuroscience. It may unfortunately be true that he could not get this review published in many neuroscience journals because it attacks too many sacred (behavioristic) cows. Panksepp has given readers of Consciousness and Cognition a nicely condensed summary of much of his classic 1998 textbook, Affective Neuroscience. I'm reasonably confident that future neuroscience students will look on that textbook as one of the seminal publications on the subject of emotion and the brain, much as we might now look back on Luria's Higher Cortical Functions in Man, or Paul MacLean's classic work, The Triune Brain. There is probably little that I can add to his elegant presentation of the basic affective neuroscience findings, but I would like to highlight a few key issues for the reader.

    According to Jaak Panksepp's Affective Neuroscience Theory and the derived self-report measure, the Affective Neuroscience Personality Scales (ANPS), differences in the responsiveness of primary emotional systems form the basis of human personality. In order to investigate neuronal correlates of personality, the underlying neuronal circuits of the primary emotional systems were analyzed in the present fMRI-study by associating the ANPS to functional connectivity in the resting brain. N=120 healthy participants were invited for the present study. The results were reinvestigated in an independent, smaller sample of N=52 participants. A seed-based whole brain approach was conducted with seed-regions bilaterally in the basolateral and superficial amygdalae. The selection of seed-regions was based on meta-analytic data on affective processing and the Juelich histological atlas. Multiple regression analyses on the functional connectivity maps revealed associations with the SADNESS-scale in both samples. Functional resting-state connectivity between the left basolateral amygdala and a cluster in the postcentral gyrus, and between the right basolateral amygdala and clusters in the superior parietal lobe and subgyral in the parietal lobe was associated with SADNESS. No other ANPS-scale revealed replicable results. The present findings give first insights into the neuronal basis of the SADNESS-scale of the ANPS and support the idea of underlying neuronal circuits. In combination with previous research on genetic associations of the ANPS functional resting-state connectivity is discussed as a possible endophenotype of personality.

    Since George Herbert Mead studied "the social self" and the interactionists went further in distinguishing "images of self", a lecture on the building up of a Brazilian medical identity should try to focus on the patterns of self-images, presented images, and aspired-to images among the Brazilian medical elites during the First Republic (1889-1930). In no other period of Brazilian history were those "images" of professional identity so close--in contrast, later periods of Brazilian history witnessed an almost permanent "collision" or the clashing of such images among public health specialists. Oswaldo Cruz, Carlos Chagas, Artur Neiva and Belisário Pena are perhaps the best examples of successful careers as "sanitarians" (to recall John Duffy's historical work on luminaries before and after the "New Public Health" in the United States), and as important political actors during Brazil's First Republic. In light of the prominent political, policy-oriented, and scientific roles public health professionals played in Brazil, it is interesting to suggest that in large part such prominence resulted from the symbolic impact of the ideologies of sanitary reform on the political agenda of that period of Brazilian history. Where many studies look for personal rivalries and disputes around Chagas and Neiva as public figures, we may also see the importance of finding identity-building processes among public health specialists as an integrated group (e.g., trying to appear as "significant others" for the new generations of medical graduates in the country), regardless of existing rivalries. Cruz and Chagas, especially, were names with great impact in the Brazilian press (pro and con), a circumstance made possible largely by their easy and direct access to the Brazilian presidents Rodrigues Alves and Epitácio Pessoa, and, most clearly, by public health being one of Brazil's political priorities to find a place among the "civilized nations" of the world. A task that further

This result suggests that the Ca-O bonds in CaOCa possess covalent character in the 1A1 excited state and ionic character in the 1Σg^+ ground state. The current results, as well as those from ongoing studies will be presented. B. Ostojici, P.R. Bunker, P.

  13. Rodent Empathy and Affective Neuroscience

    In the past few years, several experimental studies have suggested that empathy occurs in the social lives of rodents. This indicates that rodent behavioral models can be developed in an attempt to elucidate the mechanistic substrates of empathy at levels that have heretofore been unavailable. For example, the finding that mice from certain inbred strains express behavioral and physiological responses to conspecific distress, while others do not, underscores that the genetic underpinnings of empathy are specifiable and that in the future they could be harnessed to develop new therapies for human psychosocial impairments. However, the advent of rodent models of empathy is met at the outset with a number of theoretical and semantic problems that are similar to those previously confronted by studies of empathy in humans. The distinct underlying components of empathy must be differentiated from one another and from lay usage of the term. The primary goal of this paper is to review a set of seminal studies that are directly relevant to developing a concept of empathy in rodents. We first consider some of the psychological phenomena that have been associated with empathy, and within this context, we consider the component processes, or endophenotypes of rodent empathy. We then review a series of recent experimental studies that demonstrate the capability of rodents to detect and respond to the affective state of their social partners. We focus primarily on experiments that examine how rodents share affective experiences of fear, but we also highlight how similar types of experimental paradigms can be utilized to evaluate the possibility that rodents share positive affective experiences. Taken together, these studies were inspired by Jaak Panksepp’s theory that all mammals are capable of felt affective experiences. PMID:21672550

  14. Affective Infrastructures: Toward a Cultural Neuropsychology of Sport

    Recently there has been a turn toward considerations of embodiment, cognition, and context in sport studies. Many researchers have argued that the traditional focus on clinical psychology and performance enhancement within the discipline is incomplete, and now emphasize the importance of athletes’ social and familial contexts in a research paradigm that examines interconnections between movement, cognition, emotion, and the social and cultural context in which movement takes place. While it is important that the sport studies focus is being expanded to consider these interactions, I will argue that this model is still incomplete in that it is missing a fundamental variable – that of our evolutionary neurobiological roots. I will use the work of affective neuroscientists Jaak Panksepp and Stephen Porges to show that because sport so clearly activates neural systems that function at both proximate and ultimate levels of causation, it can be seen to serve fundamental needs for affective balance. A neurobiology of affect shows how the evolution of the mammalian autonomic nervous system has resulted in neurophysiological substrates for affective processes and stress responses, and has wide-ranging implications for sport studies in terms of suggesting what forms of coaching might be the most effective in what context. I propose the term cultural neuropsychology of sport as a descriptor for a model that examines the relationships between neurophysiological substrates and athletes’ social and familial contexts in terms of how these variables facilitate or fail to facilitate athletes’ neuroceptions of safety, which in turn have a direct impact on their performance. A cultural neuropsychological model of sport might thereby be seen to elaborate a relationship between proximate and ultimate mechanisms in concretely applied ways. PMID:22069389
