  10. The real code of leonardo da vinci.

    Science.gov (United States)

    Ose, Leiv

    2008-02-01

    Leonardo da Vinci was born in Italy. Among the researchers and scientists, he is favourably known for his remarkable efforts in scientific work. His investigations of atherosclerosis judiciously combine three separate fields of research. In 1506, he finished his masterpiece, painting of Mona Lisa. A careful clinical examination of the famous painting reveals a yellow irregular leather-like spot at the inner end of the left upper eyelid and a soft bumpy well-defined swelling of the dorsum of the right hand beneath the index finger about 3 cm long. This is probably the first case of familial hypercholesterolemia (FH). The FH code of Leonardo da Vinci was given immense consideration by scientists like Carl Muller, who described the xanthomas tuberosum and angina pectoris. On the contrary, Akira Endo searched for microbial metabolites that would inhibit HMG-CoA reductase, the rate-limiting enzyme in the synthesis of cholesterol and finally, Michael Brown and Joseph Goldstein published a remarkable series of elegant and insightful papers in the 70s and 80s. They established that the cellular uptake of low-density lipoprotein (LDL) essentially requires the LDL receptor. this was the real Code of Leonardo da Vinci.

    2013-08-20

    Leonardo da Vinci's detailed drawings are justly celebrated; however, less well known are his accounts of the structures and functions of the organs. In this paper, we focus on his illustrations of the heart, his conjectures about heart and blood vessel function, his experiments on model systems to test those conjectures, and his unprecedented conclusions about the way in which the cardiovascular system operates. In particular, da Vinci seems to have been the first to recognize that the heart is a muscle and that systole is the active phase of the pump. He also seems to have understood the functions of the auricles and pulmonary veins, identified the relationship between the cardiac cycle and the pulse, and explained the hemodynamic mechanism of valve opening and closure. He also described anatomical variations and changes in structure and function that occurred with age. We outline da Vinci's varied career and suggest ways in which his personality, experience, skills and intellectual heritage contributed to these advances in understanding. We also consider his influence on later studies in anatomy and physiology.

    Leonardo da Vinci's marvellous anatomical drawings have been praised by both artists and medical historians over the centuries. Specific reference is made here to Leonardo's drawings of the act of sexual intercourse. It is shown that his illustrations are not based purely on original observation. Rather, they are an attempt to illustrate and clarify anatomy and physiology as presented in the textbooks of the time.

  18. LEONARDO DA VINCI AND THE ORIGIN OF SEMEN.

    Science.gov (United States)

    Noble, Denis; DiFrancesco, Dario; Zancani, Diego

    2014-12-20

    It is well known that Leonardo da Vinci made several drawings of the human male anatomy. The early drawings (before 1500) were incorrect in identifying the origin of semen, where he followed accepted teaching of his time. It is widely thought that he did not correct this mistake, a view that is reflected in several biographies. In fact, he made a later drawing (after 1500) in which the description of the anatomy is remarkably accurate and must have been based on careful dissection. In addition to highlighting this fact, acknowledged previously in only one other source, this article reviews the background to Leonardo's knowledge of the relevant anatomy.

  20. [Studies of vision by Leonardo da Vinci].

    Science.gov (United States)

    Berggren, L

    2001-01-01

    Leonardo was an advocate of the intromission theory of vision. Light rays from the object to the eye caused visual perceptions which were transported to the brain ventricles via a hollow optic nerve. Leonardo introduced wax injections to explore the ventricular system. Perceptions were assumed to go to the "senso comune" in the middle (3rd) ventricle, also the seat of the soul. The processing station "imprensiva" in the anterior lateral horns together with memory "memoria" in th posterior (4th) ventricle integrated the visual perceptions to visual experience. - Leonardo's sketches with circular lenses in the center of the eye reveal that his dependence on medieval optics prevailed over anatomical observations. Drawings of the anatomy of the sectioned eye are missing although Leonardo had invented a new embedding technique. In order to dissect the eye without spilling its contents, the eye was first boiled in egg white and then cut. The procedure was now repeated and showed that the ovoid lens after boiling had become spherical. - Leonardo described that light rays were refracted and reflected in the eye but his imperfect anatomy prevented a development of physiological optics. He was, however, the first to compare the eye with a pin-hole camera (camera obscura). Leonardo's drawings of the inverted pictures on the back wall of a camera obscura inspired to its use as an instrument for artistic practice. The camera obscura was for centuries a model for explaining human vision.

  1. [Regarding the Manuscript D " Dell' occhio " of Leonardo da Vinci].

    Science.gov (United States)

    Heitz, Robert F

    2009-01-01

    Leonardo da Vinci's Manuscript D consists of five double pages sheets, which, folded in two, comprise ten folios. This document, in the old Tuscan dialect and mirror writing, reveals the ideas of Leonardo on the anatomy of the eye in relation to the formation of images and visual perception. Leonardo explains in particular the behavior of the rays in the eye in terms of refraction and reflection, and is very mechanistic in his conception of the eye and of the visual process. The most significant innovations found in these folios are the concept of the eye as a camera obscura and the intersection of light rays in the interior of the eye. His texts nevertheless show hesitation, doubts and a troubled confusion, reflecting the ideas and uncertainties of his era. He did not share his results in his lifetime, despite both printing and etching being readily available to him.

  2. Leonardo da Vinci: the search for the soul.

    Science.gov (United States)

    Del Maestro, R F

    1998-11-01

    The human race has always contemplated the question of the anatomical location of the soul. During the Renaissance the controversy crystallized into those individuals who supported the heart ("cardiocentric soul") and others who supported the brain ("cephalocentric soul") as the abode for this elusive entity. Leonardo da Vinci (1452-1519) joined a long list of other explorers in the "search for the soul." The method he used to resolve this anatomical problem involved the accumulation of information from ancient and contemporary sources, careful notetaking, discussions with acknowledged experts, and his own personal search for the truth. Leonardo used a myriad of innovative methods acquired from his knowledge of painting, sculpture, and architecture to define more clearly the site of the "senso comune"--the soul. In this review the author examines the sources of this ancient question, the knowledge base tapped by Leonardo for his personal search for the soul, and the views of key individuals who followed him.

    In the drawing of coitus by Leonardo da Vinci are pictured the contemporary hypotheses regarding this act. The authors analyze the mamillaruteral connection depicted by the artist and grow up to believe that this is a hypothetical kiveris vena, female vein described by Anatomist Master Nicolai Physicus from the Salerno School. The Hebrew roots were found in the name. The connection is described also by Mondino in The Anathomia. The same connection can be found in the picture of the pregnant woman in Fasciculus Medicinæ by Johannes De Ketham.

  6. Leonardo da Vinci and His Contributions to Cartography

    Directory of Open Access Journals (Sweden)

    Branko Puceković

    2013-12-01

    Full Text Available The archetypal Renaissance figure Leonardo da Vinci was truly a universal man (Ital. – uomo universale. There is no area of human activity that failed to attract his attention, or that does not bear a trace of his deliberations. In the field of fine art, Leonardo is famous for his masterpieces: the Mona Lisa, the Last Supper, the Virgin of the Rocks, and other, unfinished works, for example, St. Jerome in the Wilderness, and the Adoration of the Magi. He did not leave any works of sculpture, though he did create sketches and drawings. His legacy includes approximately 13,000 sheets of notes and drawings of anatomy, architecture, war and flying machines, plants and animals, all annotated in a reversed mirror-script. In his works of art, he brought his compositions to perfection by using the principles of perspective and the techniques of chiaroscuro and sfumato. Leonardo designed war machines and produced several plans and topographical maps for the powerful men of his time, under whose patronage he worked, such as dukes, kings and popes. This article presents a brief account of his most famous cartographical works: the plan of Imola, three topographic maps of Tuscany, the Chiana valley, the Pontine Marshes and western Tuscany, and a world map (Mappa Mundi. Leonardo skilfully made use of his fascination with landscapes, incorporating them as backdrops in his masterpieces.

  7. Leonardo da Vinci and the first hemodynamic observations.

    Science.gov (United States)

    Martins e Silva, J

    2008-02-01

    Leonardo da Vinci was a genius whose accomplishments and ideas come down to us today, five centuries later, with the freshness of innovation and the fascination of discovery. This brief review begins with a summary of Leonardo's life and a description of the most important works of art that he bequeathed us, and then concentrates on his last great challenge. There was a point at which Leonardo's passion for art gave way to the study of human anatomy, not only to improve his drawing but to go beyond what had been simply a representation of form to understand the underlying functioning. Among his many interests, we focus on his study of the heart and blood vessels, which he observed carefully in animals and human autopsies, and reproduced in drawings of great quality with annotations of astonishing acuteness. The experience that he had acquired from observing the flow of water in currents and around obstacles, and the conclusions that he drew concerning hydrodynamics, were central to his interpretation of the mechanisms of the heart and of blood flow, to which he devoted much of his time between 1508 and 1513. From these studies, immortalized in drawings of great clarity, come what are acknowledged to be the first hemodynamic records, in which Leonardo demonstrates the characteristics of blood flow in the aorta and great vessels and the importance of blood reflux and the formation of eddies in the sinus in aortic valve his assiduous and careful observations, and his subsequent deductions, Leonardo put forward detailed findings on hemodynamic questions that advanced technology has only recently enabled us to confirm.

  8. Xanthelasma and lipoma in Leonardo da Vinci's Mona Lisa.

    Dequeker, Jan; Muls, Erik; Leenders, Kathleen

    2004-08-01

    The painting Mona Lisa in the Louvre, Paris, by Leonardo da Vinci (1503-1506), shows skin alterations at the inner end of the left upper eyelid similar to xanthelasma, and a swelling of the dorsum of the right hand suggestive of a subcutaneous lipoma. These findings in a 25-30 year old woman, who died at the age of 37, may be indicative of essential hyperlipidemia, a strong risk factor for ischemic heart disease in middle age. As far as is known, this portrait of Mona Lisa painted in 1506 is the first evidence that xanthelasma and lipoma were prevalent in the sixteenth century, long before the first description by Addison and Gall in 1851.

    2009-01-01

    The aim of this article is to reflect on the relationship between art and science so far as it concerns a symposium on neurosciences. We undertake a historical overview of that relationship, paying particular attention to the sui generis case of Leonardo da Vinci, who very often is regarded as the man who worked on art and science with equal ease. We then explain why his idea of merging these two forms of knowledge failed, considering the clear-cut distinction between art and science in his time. With this clarification, we explore the matter today. We look at Raphael's The Transfiguration, in which the representation of the possessed boy is seen by neuroscientists as indicative of an epileptic seizure. We also look at the ideas of neuroscientists Semir Zeki and Vilayanur Ramachandran, who study particular aspects of brain function and suggest a new merging of art and science.

  10. Leonardo da Vinci: engineer, bioengineer, anatomist, and artist.

    Science.gov (United States)

    West, John B

    2017-03-01

    Leonardo da Vinci (1452-1519) enjoys a reputation as one of the most talented people of all time in the history of science and the arts. However, little attention has been given to his contributions to physiology. One of his main interests was engineering, and he was fascinated by structural problems and the flow patterns of liquids. He also produced a large number of ingenious designs for warfare and a variety of highly original flying machines. But of particular interest to us are his contributions to bioengineering and how he used his knowledge of basic physical principles to throw light on physiological function. For example, he produced new insights into the mechanics of breathing including the action of the ribs and diaphragm. He was the first person to understand the different roles of the internal and external intercostal muscles. He had novel ideas about the airways including the mode of airflow in them. He also worked on the cardiovascular system and had a special interest in the pulmonary circulation. But, interestingly, he was not able to completely divorce his views from those of Galen, in that although he could not see pores in the interventricular septum of the heart, one of his drawings included them. Leonardo was a talented anatomist who made many striking drawings of the human body. Finally, his reputation for many people is based on his paintings including the Mona Lisa that apparently attracts more viewers than any other painting in the world.

    2010-01-01

    Leonardo da Vinci (April 15, 1452 to May 2, 1519) was an Italian Renaissance architect, musician, anatomist, inventor, engineer, sculptor, geometer, and painter. It has been gleaned from the many available historical documents that da Vinci was a vegetarian who respected and loved animals, and that he suffered from right hemiparesis in the last 5 years of his life. A vegetarian diet has both positive and negative influences on the cerebrovascular system. In this report, a possible relation between a vegetarian diet and stroke is discussed from various perspectives as related to Leonardo da Vinci's stroke. Copyright (c) 2010 S. Karger AG, Basel.

    Leonardo da Vinci (1452-1519) can be called one of the earliest contributors to the history of anatomy and, by extension, the study of medicine. He may have even overshadowed Andreas Vesalius (1514-1564), the so-called founder of human anatomy, if his works had been published within his lifetime. While some of the best illustrations of their time, with our modern knowledge of anatomy, it is clear that many of da Vinci's depictions of human anatomy are inaccurate. However, he also made significant discoveries in anatomy and remarkable predictions of facts he could not yet discover with the technology available to him. Additionally, da Vinci was largely influenced by Greek anatomists, as indicated from his ideas about anatomical structure. In this historical review, we describe da Vinci's history, influences, and discoveries in anatomical research and his depictions and errors with regards to the musculoskeletal system, cardiovascular system, nervous system, and other organs.

  20. On the purported discovery of the bronchial circulation by Leonardo da Vinci.

    Science.gov (United States)

    Mitzner, W; Wagner, E

    1992-09-01

    Among modern physiologists and anatomists, there has been a nearly universal acceptance that Leonardo da Vinci was the first to identify the anatomy of the bronchial circulation. However, because of certain ambiguities in both his anatomic drawing that was supposed to have shown this circulation and the accompanying descriptive text, we questioned whether he really could have been the first to discover this small but important vasculature. To address this question, we set out to repeat Leonardo's dissections in the ox. We reasoned that perhaps the normally tiny bronchial vessels would be considerably more noticeable in this very large species. Our dissections, however, failed to provide any evidence that Leonardo's drawing was that of the bronchial circulation. Furthermore we observed a set of distinct small pulmonary veins to the left upper and right middle lobes that Leonardo, given his lack of understanding of the function of the lung and its circulation, could have easily mistaken for a separate circulation. We thus conclude that Leonardo da Vinci did not describe the anatomy of the bronchial circulation. We believe that the first person to clearly and unequivocally describe the anatomy of this circulation was the Dutch Professor of Anatomy and Botany, Frederich Ruysch.

    The discoloration of ancient paper, due to the development of oxidized groups acting as chromophores in its chief component, cellulose, is responsible for severe visual degradation in ancient artifacts. By adopting a non-destructive approach based on the combination of optical reflectance measurements and time-dependent density functional theory ab-initio calculations, we describe and quantify the chromophores affecting Leonardo da Vinci's iconic self-portrait. Their relative concentrations are very similar to those measured in modern and ancient samples aged in humid environments. This analysis quantifies the present level of optical degradation of the Leonardo da Vinci's self-portrait which, compared with future measurements, will assess its degradation rate. This is a fundamental information in order to plan appropriate conservation strategies.

    The handedness of Leonardo da Vinci is controversial. Although there is little doubt that many of his well-attributed drawings were drawn with the left hand, the hatch marks of the shading going downwards from left to right, it is not clear that he was a natural left-hander, there being some suggestion that he may have become left-handed as the…

  4. Urodynamics in the anatomical work of Leonardo da Vinci (1452-1519).

    1999-06-01

    Leonardo da Vinci (1452-1519) incorporates the symbiosis of art and medicine and can be addressed as the founder of medical illustration in the time of the Renaissance. His anatomy studies were not published in his time, which explains why Leonardo's outstanding knowledge of anatomy, physiology, and medicine had no impact on his scientific contemporaries and is therefore primarily of retrospective importance in the history of medicine. The collection of anatomical illustrations remained unknown until their rediscovery in the eighteenth century and their wide publication at the beginning of our century. This article systematically reviews Leonardo's genitourinary drawings with regard to urodynamic aspects of the upper and lower urinary tract, highlighting topics such as vesicoureteral reflux and urinary sphincter mechanisms.

  5. Leonardo Da Vinci, the genius and the monsters. Casual encounters?

    Science.gov (United States)

    Ciseri, Lorenzo Montemagno

    2014-01-01

    This article analyses Leonardo's interest in monsters and deformed reality, one of the lesser known aspects of his vast and multifaceted output. With the possible exception of his studies of physiognomy, relevant drawings, sketches and short stories represent a marginal aspect of his work, but they are nevertheless significant for historians of teratology. The purpose of this study is to provide a broad overview of the relationship between Leonardo and both the literature on mythological monsters and the reports on monstrous births that he either read about or witnessed personally. While aspects of his appreciation and attention to beauty and the pursuit of perfection and good proportions are the elements most emphasised in Leonardo's work, other no less interesting aspects related to deformity have been considered of marginal importance. My analysis will demonstrate that Leonardo approached the realm of monstrosity as if he considered abnormality a mirror of normality, deformity a mirror of harmony, and disease a mirror of health, as if to emphasise that, ultimately, it is the monster that gives the world the gift of normality. Two special cases of monstrosity are analysed: the famous monster of Ravenna, whose image was found among his papers, and a very rare case of parasitic conjoined twins (thoracopagus parasiticus) portrayed for the first time alive, probably in Florence, by Leonardo himself.

  7. Leonardo da Vinci and Andreas Vesalius; the shoulder girdle and the spine, a comparison.

    Science.gov (United States)

    Ganseman, Y; Broos, P

    2008-01-01

    Leonardo Da Vinci and Andreas Vesalius were two important renaissance persons; Vesalius was a surgeon-anatomist who delivered innovative work on the study of the human body, Leonardo da Vinci was an artist who delivered strikingly accurate and beautiful drawings on the human body. Below we compare both masters with regard to their knowledge of the working of the muscles, their method and system of dissection and their system and presentation of the drawings. The investigation consisted of a comparison between both anatomists, in particular concerning their study on the shoulder girdle and spine, by reviewing their original work as well as already existing literature on this subject. The investigation led to the conclusion that the drawings mentioned meant a change in history, and were of high quality, centuries ahead of their time. Both were anatomists, both were revolutionary, only one changed history at the moment itself, while the other changed history centuries later. Leonardo has made beautiful drawings that are at a match with the drawings of today or are even better. Vesalius set the start for medicine as a science as it is until this day. Their lives differed as strongly as their impact. In the light of their time, the achievement they made was extraordinary.

  8. [The Vitruvian Man: an anatomical drawing for proportions by Leonardo Da Vinci].

    Science.gov (United States)

    Le Floch-Prigent, P

    2008-12-01

    The aim of the study was to find out and to analyse the text by Vitruvius which inspired the famous drawing by Leonardo da Vinci (circa 1490) kept in the Galleria dell'Accademia, in Venezia, Italy: the man inscribed in one circle and in one square. The book "de Architectura" by Vitruvius Marcus Pollio was printed several times since the Renaissance when both the roman architecture of antiquity and this text became very popular. From a French translation by Claude Perrault in 1864, it became easy to find a French translation with the original text in Latin (Paris, 2003, Les Belles Lettres, French text by Pierre Gros). The drawing by Leonardo da Vinci illustrates with great accuracy and fidelity the quotation of Vitruvius (with the exception of two of the 12 main relationships). The genius of Leonardo da Vinci was to keep only one trunk, head and neck for two pairs of limbs: scapular and pelvic; to make the circle tangent to the lower edge of the square; to adjust a few features of the quotation for the equilibrium of the whole figure; and of course to bring his incredible skill as a drawer (one of the best of his century). The drawing was made on a sheet of paper 344x245mm, in black ink which became dark brown with time; several lines complete the figure above and below; a short caption and a horizontal scale appear just under the drawing. The celebrity of the drawing, a symbol of the Renaissance, of the equilibrium of man and mankind, of the universality of the artists and intellectuals of the time (Humanism) made it iconic and it has been constantly reproduced and adapted especially for advertisement and logos, not only in the medical field.

    Madonna dei Fusi (`Madonna of the Yarnwider') is a spectacular example of Italian Renaissance painting, attributed to Leonardo da Vinci. The aim of this study is to give an account of past restoration procedures. The evidence of a former retouching campaign will be presented with cross-sectional images obtained non-invasively with Optical Coherence Tomography (OCT). Specifically, the locations of overpaintings/retouchings with respect to the original paint layer and secondary varnishes will be given. Additionally, the evidence of a former transfer of the pictorial layer to the new canvas support by detecting the presence of its structure incised into paint layer will be shown.

  10. Leonardo da Vinci's "A skull sectioned": skull and dental formula revisited.

    Science.gov (United States)

    Gerrits, Peter O; Veening, Jan G

    2013-05-01

    What can be learned from historical anatomical drawings and how to incorporate these drawings into anatomical teaching? The drawing "A skull sectioned" (RL 19058v) by Leonardo da Vinci (1452-1519), hides more detailed information than reported earlier. A well-chosen section cut explores sectioned paranasal sinuses and ductus nasolacrimalis. A dissected lateral wall of the maxilla is also present. Furthermore, at the level of the foramen mentale, the drawing displays compact and spongious bony components, together with a cross-section through the foramen mentale and its connection with the canalis mandibulae. Leonardo was the first to describe a correct dental formula (6424) and made efforts to place this formula above the related dental elements. However, taking into account, the morphological features of the individual elements of the maxilla, it can be suggested that Leonardo sketched a "peculiar dental element" on the position of the right maxillary premolar in the dental sketch. The fact that the author did not make any comment on that special element is remarkable. Leonardo could have had sufficient knowledge of the precise morphology of maxillary and mandibular premolars, since the author depicted these elements in the dissected skull. The fact that the author also had access to premolars in situ corroborates our suggestion that "something went wrong" in this part of the drawing. The present study shows that historical anatomical drawings are very useful for interactive learning of detailed anatomy for students in medicine and dentistry.

  11. The uncatchable smile in Leonardo da Vinci's La Bella Principessa portrait.

    2015-08-01

    A portrait of uncertain origin recently came to light which, after extensive research and examination, was shown to be that rarest of things: a newly discovered Leonardo da Vinci painting entitled La Bella Principessa. This research presents a new illusion which is similar to that identified in the Mona Lisa; La Bella Principessa's mouth appears to change slant depending on both the Viewing Distance and the Level of Blur applied to a digital version of the portrait. Through a series of psychophysics experiments, it was found that a perceived change in the slant of the La Bella Principessa's mouth influences her expression of contentment thus generating an illusion that we have coined the "uncatchable smile". The elusive quality of the Mona Lisa's smile has been previously reported (Science, 290 (2000) 1299) and so the existence of a similar illusion in a portrait painted prior to the Mona Lisa becomes more interesting. The question remains whether Leonardo da Vinci intended this illusion. In any case, it can be argued that the ambiguity created adds to the portrait's allure. Copyright © 2015 Elsevier Ltd.

    Following the discovery of discoloration on some pages of the Atlantic Codex (AC) of Leonardo da Vinci kept in the Biblioteca Ambrosiana in Milan, some investigations have been carried out to verify the presence of microorganisms, such as bacteria and fungi. To verify the presence of microorganisms a noninvasive method of sampling has been used that was efficient and allowed us to highlight the microbial facies of the material that was examined using conventional microbiological techniques. The microclimatic conditions in the storage room as well as the water content of the volume were also assessed. The combined observations allowed the conclusion that the discoloration of suspected biological origin on some pages of AC is not related to the presence or current attack of microbial agents.

  18. Bell's palsy: the answer to the riddle of Leonardo da Vinci's 'Mona Lisa'.

    Maloney, W J

    2011-05-01

    The smile of the famed portrait 'The Mona Lisa' has perplexed both art historians and researchers for the past 500 years. There has been a multitude of theories expounded to explain the nature of the model's enigmatic smile. The origin of the model's wry smile can be demonstrated through a careful analysis of both documented facts concerning the portrait--some gathered only recently through the use of modern technology--and a knowledge of the clinical presentation of Bell's palsy. Bell's palsy is more prevalent in women who are either pregnant or who have recently given birth. This paper postulates that the smile of the portrait's model was due to Leonardo da Vinci's anatomically precise representation of a new mother affected by Bell's palsy subsequent to her recent pregnancy.

    Cicero, Raúl; Criales, José Luis; Cardoso, Manuel

    2009-01-01

    The impressive development of computed tomography (CT) techniques such as the three dimensional helical CT produces a spatial image of the thoracic skull. At the beginning of the 16th century Leonardo da Vinci drew with great precision the thorax oseum. These drawings show an outstanding similarity with the images obtained by three dimensional helical CT. The cumbersome task of the Renaissance genius is a prime example of the careful study of human anatomy. Modern imaging techniques require perfect anatomic knowledge of the human body in order to generate exact interpretations of images. Leonardo's example is alive for anybody devoted to modern imaging studies.

    2011-12-01

    What's known on the subject? and What does the study add? Numerous urological procedures can now be performed with robotic assistance. Though not definitely proven to be superior to conventional laparoscopy or traditional open surgery in the setting of a randomised trial, in experienced centres robot-assisted surgery allows for excellent surgical outcomes and is a valuable tool to augment modern surgical practice. Our review highlights the depth of history that underpins the robotic surgical platform we utilise today, whilst also detailing the current place of robot-assisted surgery in urology in 2011. The evolution of robots in general and as platforms to augment surgical practice is an intriguing story that spans cultures, continents and centuries. A timeline from Yan Shi (1023-957 bc), Archytas of Tarentum (400 bc), Aristotle (322 bc), Heron of Alexandria (10-70 ad), Leonardo da Vinci (1495), the Industrial Revolution (1790), 'telepresence' (1950) and to the da Vinci(®) Surgical System (1999), shows the incredible depth of history and development that underpins the modern surgical robot we use to treat our patients. Robot-assisted surgery is now well-established in Urology and although not currently regarded as a 'gold standard' approach for any urological procedure, it is being increasingly used for index operations of the prostate, kidney and bladder. We perceive that robotic evolution will continue infinitely, securing the place of robots in the history of Urological surgery. Herein, we detail the history of robots in general, in surgery and in Urology, highlighting the current place of robot-assisted surgery in radical prostatectomy, partial nephrectomy, pyeloplasty and radical cystectomy.

    2011-01-01

    In 2006, after a visual inspection of the Leonardo da Vinci's Atlantic Codex by a scholar, active molds were reported to have been present on Codex pages showing areas of staining. In the present paper, molecular methods were used to assess the current microbiological risk to stained pages of the manuscript. Bacterial and fungal communities were sampled by a non-invasive technique employing nitrocellulose membranes. Denaturing gradient gel electrophoresis of 16 S rRNA gene and internal transcribed space regions were carried out to study the structure of the bacterial and fungal communities and band patterns were analyzed by the multivariate technique of principal component analysis. Any relationship between the presence of an active microbial community and staining was excluded. The presence of potential biodeteriogens was evaluated by constructing bacterial and fungal clone libraries, analyzing them by an operational taxonomic unit (OTU) approach. Among the bacteria, some OTUs were associated with species found on floors in clean room while others were identified with human skin contamination. Some fungal OTU representatives were potential biodeteriogens that, under proper thermo-hygrometric conditions, could grow. The retrieval of these potential biodeteriogens and microorganisms related to human skin suggests the need for a continuous and rigorous monitoring of the environmental conditions, and the need to improve handling procedures.

  5. The Science Museum and the Leonardo da Vinci Quincentenary Exhibition of 1952

    Professor Jim Bennett

    2015-11-01

    Full Text Available A large and successful exhibition to mark the 500th anniversary of the birth of Leonardo da Vinci was held at the Royal Academy, Burlington House, London, in 1952. It was an important event for the public appreciation of Leonardo’s genius. The proposal for the exhibition had come from the Science Museum, whose staff arranged a ‘scientific section’ of the exhibition, providing and displaying photographs and models. The story of these early models is particularly interesting in the light of the subsequent expansion in the use of mechanical models and animations to interpret and present Leonardo’s work. Questions that surrounded their introduction are accentuated by the ubiquity of models today. Some of the 1952 models will be displayed at the Science Museum in 2016, alongside an exhibition of a large group of ‘historical models’ first displayed in Milan in 1953. The occasion should provoke some thoughtful consideration of the current influence of this tool for research and display.

    1996-01-01

    The present study was conducted to examine whether the thumb rule of Leonardo da Vinci could be an objective method in the determination of the natural and artistic proportions of human face. In this study, a sample of 400 subjects (200 male and 200 female, 22-25 years old) was used. Measurements were made of the length of thumb, the length of ear, the approximate distances between the hair line and the glabella or eyebrows, between the glabella or eyebrows and the tip of the nose and the distance between the nose and the chin, and the distance between the ear and the lateral aspect of the eye. The results obtained in the males and females showed significant (p < 0.01) correlations between the length of thumb and the proportions of the face examined in the study. Additionally, the height of the face was found to be almost three times the length of the thumb. However, the measurements obtained from female subjects were on average smaller than those taken from males. The results obtained in this experiment could be of value in understanding of the evaluation of the face for the people working in plastic surgery or art.

  7. How did Leonardo perceive himself? Metric iconography of da Vinci's self-portraits

    Science.gov (United States)

    Tyler, Christopher W.

    2010-02-01

    Some eighteen portraits are now recognized of Leonardo in old age, consolidating the impression from his bestestablished self-portrait of an old man with long white hair and beard. However, his appearance when younger is generally regarded as unknown, although he was described as very beautiful as a youth. Application of the principles of metric iconography, the study of the quantitative analysis of the painted images, provides an avenue for the identification of other portraits that may be proposed as valid portraits of Leonardo during various stages of his life, by himself and by his contemporaries. Overall, this approach identifies portraits of Leonardo by Verrocchio, Raphael, Botticelli, and others. Beyond this physiognomic analysis, Leonardo's first known drawing provides further insight into his core motivations. Topographic considerations make clear that the drawing is of the hills behind Vinci with a view overlooking the rocky promontory of the town and the plain stretching out before it. The outcroppings in the foreground bear a striking resemblance to those of his unique composition, 'The Virgin of the Rocks', suggesting a deep childhood appreciation of this wild terrain. and an identification with that religious man of the mountains, John the Baptist, who was also the topic of Leonardo's last known painting. Following this trail leads to a line of possible selfportraits continuing the age-regression concept back to a self view at about two years of age.

  8. Unfolding Leonardo DA Vinci's Globe (ad 1504) to Reveal its Historical World Map

    Science.gov (United States)

    Verhoeven, G. J.; Missinne, S. J.

    2017-08-01

    This paper reports in detail on the image-based modelling and unwrapping approach used to create a two-dimensional projected map of an astonishing ostrich egg globe from AD 1504. This miniature egg globe is not only the oldest extant engraved globe, but it is also the oldest post-Columbian globe of the world and the first ever to depict Newfoundland and many other territories. The intention of digitally recording the surface geometry and colour of this unique artefact was to portray the original layout of the world map used by the Florentine Renaissance artist to make this globe. In addition, it was expected to substantiate iconographical details, which are hard to study at its scale of 1:80,000,000. The ostrich egg globe is the prototype of the Lenox Globe kept at the New York Public Library. The latter is very beneficial to examine how the egg globe looked like before being glued together at its equator. On the other hand, unfolding the map engraved in the ostrich egg halves enables a more detailed study of the remarkable details visible on both globes, since the engravings on the quasi-white egg surface are much easier to discern than those of the highly reflective red copper Lenox Globe. Finally, a detailed study of the unwrapped 3D surface is essential to learn more about the world vision of its creator and the incredible efforts that went into making this globe. Thanks to some particular pictographic details as well as the way in which the engravings are applied (by a left-handed person), the globe artist can be identified as Leonardo da Vinci.

Podemos, contudo, perceber uma constante tentativa em prol de uma revisão histórica acerca do papel desempenhado por Leonardo. Observando a história dessas revisões, é possível detectar aspectos significativos das perspectivas históricas e historiográficas dos envolvidos nessa discussão. É o que pretendemos fazer neste trabalho, focando a controvérsia entre Duhem, por um lado, e Sarton, Koyré e Rossi, por outro. Ao fazer isso, buscamos discutir alguns traços que marcam a distinção entre uma historiografia mais antiga e a nova historiografia da ciência, tal como exposta por Thomas Kuhn.

  10. The oldest anatomical handmade skull of the world c. 1508: 'the ugliness of growing old' attributed to Leonardo da Vinci.

    Missinne, Stefaan J

    2014-06-01

    The author discusses a previously unknown early sixteenth-century renaissance handmade anatomical miniature skull. The small, naturalistic skull made from an agate (calcedonia) stone mixture (mistioni) shows remarkable osteologic details. Dr. Saban was the first to link the skull to Leonardo. The three-dimensional perspective of and the search for the senso comune are discussed. Anatomical errors both in the drawings of Leonardo and this skull are presented. The article ends with the issue of physiognomy, his grotesque faces, the Perspective Communis and his experimenting c. 1508 with the stone mixture and the human skull. Evidence, including the Italian scale based on Crazie and Braccia, chemical analysis leading to a mine in Volterra and Leonardo's search for the soul in the skull are presented. Written references in the inventory of Salai (1524), the inventory of the Villa Riposo (Raffaello Borghini 1584) and Don Ambrogio Mazenta (1635) are reviewed. The author attributes the skull c. 1508 to Leonardo da Vinci.

The overall aim of the LEONARDO-DA-VINCI pilot project "e-learning-assistant" was to create new didactical and technical e-learning tools for Europe-wide use in nursing education. Based on a new situation-oriented learning approach, nursing teachers enrolled in the project were instructed to adapt, develop and implement e- and blended learning units. According to the training contents nursing modules were developed by teachers from partner institutions, implemented in the project centers and evaluated by students. The user-package "e-learning-assistant" as a product of the project includes two teacher training units, the authoring tool "synapse" to create situation-based e-learning units, a student's learning platform containing blended learning modules in nursing and an open sourced web-based communication centre.

  14. [Freud's identification with men who had 2 mothers: Oedipus, Leonardo da Vinci, Michealangelo and Moses].

    Harsch, H E

    1994-02-01

    In view of the fact that as a child Sigmund Freud was looked after by two mothers--his actual mother and a nursemaid--it is hardly surprising that traces of this pre-oedipal situation, fraught as it was with traumatisation and loss, should be discernible in the works of the creator of psychoanalysis. Freud's continued preoccupation with the Oedipus myth, his interest in "great men" like da Vinci and Michelangelo, and finally his identification with the figure of Moses are pointers not only to the paternal dimension (as long suggested by Freud's biographers) but also to the maternal dimension and its significance for Freud's life and work. The author demonstrates that those mythical and historical figures which Freud identified with--Oedipus, da Vinci, Michelangelo, Moses--themselves all had two mothers and sublimated this traumatic experience into outstanding achievements, the same being true of Freud himself "who solved the famous riddle and was a most powerful man".

    2015-11-01

    This work focuses on the composition and microstructure of the lead white pigment employed in a set of paintworks, using a combination of µ-XRD and 2D scanning XRF, directly applied on five drapery studies attributed to Leonardo da Vinci (1452-1519) and conserved in the Département des Arts Graphiques, Musée du Louvre and in the Musée des Beaux- Arts de Rennes. Trace elements present in the composition as well as in the lead white highlights were imaged by 2D scanning XRF. Mineral phases were determined in a fully noninvasive way using a special µ-XRD diffractometer. Phase proportions were estimated by Rietveld refinement. The analytical results obtained will contribute to differentiate lead white qualities and to highlight the artist's technique.

  16. The mother relationship and artistic inhibition in the lives of Leonardo da Vinci and Erik H. Erikson.

    Capps, Donald

    2008-12-01

    In four earlier articles, I focused on the theme of the relationship of melancholia and the mother, and suggested that the melancholic self may experience humor (Capps, 2007a), play (Capps, 2007b), dreams (Capps, 2008a), and art (Capps, 2008b) as restorative resources. I argued that Erik H. Erikson found these resources to be valuable remedies for his own melancholic condition, which had its origins in the fact that he was illegitimate and was raised solely by his mother until he was three years old, when she remarried. In this article, I focus on two themes in Freud's Leonardo da Vinci and a memory of his childhood (1964): Leonardo's relationship with his mother in early childhood and his inhibitions as an artist. I relate these two themes to Erikson's own early childhood and his failure to achieve his goal as an aspiring artist in his early twenties. The article concludes with a discussion of Erikson's frustrated aspirations to become an artist and his emphasis, in his psychoanalytic work, on children's play.

    2004-06-01

    This study confirms Leonardo's claim to have experimented on the bovine eye to determine the internal anatomy of the eye. The experiment, as described by Leonardo, was repeated in our laboratory. The study further discusses Leonardo's primary interest in the study of the eye (especially the lens), to determine how the image of an object which enters the eye in an inverted form is righted. The study shows the evolution of Leonardo's understanding of the anatomy and the physiology of vision. Initially, in keeping with his reading of the literature, the lens was placed in the centre but he made it globular. Later he promulgated two theories, reflection from the uvea and refraction within the lens to explain reversal of the image in the eye. Subsequently he rejected the first theory and, putting credence in the second theory, experimented (1509) to show that the lens is globular and is centrally placed. The fact that the present knowledge about the lens is at variance from his findings is not because he did not carry out the experiment, as suggested by some modern authors, but because of the limitation of the techniques available to him at the time.

    2016-08-01

    Full Text Available The perfect memory that informs our local autistic facet is insufficient to deal with the unforeseen change that challenges our nonlocal artistic facet. The loss of quantum nonlocality leads autistics to fail tests rooted in overcoming the less-than-perfect ambiguity that elicits our creativity. The psychological structure by which perfect memory and less-than-perfect creativity empower each other remains in darkness. This article broaches the hypothesis that Leonardo da Vinci envisioned the union of local perfection and nonlocal less-than-perfection, and that he hid his insight in the Adoration of the Magi. Leonardo’s knowledge - expressed here as the logos heuristic—guides a psychological interpretation of the smile of Mona Lisa; of the four avatars of the Vitruvian Man; of the recognition and location of Leonardo’s unknown painting Natività; of the exact location of his lost work, Battaglia di Anghiari; and of a 39,000-year-old abstract engraving in Gorham’s cave at Gibraltar. Logos can be used to single out local, nonlocal computing, and their alliance in pursuing a humanistic path to progress.

  1. Amid the possible causes of a very famous foxing: molecular and microscopic insight into Leonardo da Vinci's self‐portrait

    2015-01-01

    Summary Leonardo da Vinci's self‐portrait is affected by foxing spots. The portrait has no fungal or bacterial infections in place, but is contaminated with airborne spores and fungal material that could play a role in its disfigurement. The knowledge of the nature of the stains is of great concern because future conservation treatments should be derived from scientific investigations. The lack of reliable scientific data, due to the non‐culturability of the microorganisms inhabiting the portrait, prompted the investigation of the drawing using non‐invasive and micro‐invasive sampling, in combination with scanning electron microscope (SEM) imaging and molecular techniques. The fungus E urotium halophilicum was found in foxing spots using SEM analyses. Oxalates of fungal origin were also documented. Both findings are consistent with the hypothesis that tonophilic fungi germinate on paper metabolizing organic acids, oligosaccharides and proteic compounds, which react chemically with the material at a low water activity, forming brown products and oxidative reactions resulting in foxing spots. Additionally, molecular techniques enabled a screening of the fungi inhabiting the portrait and showed differences when different sampling techniques were employed. Swabs samples showed a high abundance of lichenized Ascomycota, while the membrane filters showed a dominance of A cremonium sp. colonizing the drawing. PMID:26111623

    3D measurement and modelling have been traditionally applied to statues, buildings, archeological sites or similar large structures, but rarely to paintings. Recently, however, 3D measurements have been performed successfully also on easel paintings, allowing to detect and document the painting's surface. We used 3D models to integrate the results of various 2D imaging techniques on a common reference frame. These applications show how the 3D shape information, complemented with 2D colour maps as well as with other types of sensory data, provide the most interesting information. The 3D data acquisition was carried out by means of two devices: a high-resolution laser micro-profilometer, composed of a commercial distance meter mounted on a scanning device, and a laser-line scanner. The 2D data acquisitions were carried out using a scanning device for simultaneous RGB colour imaging and IR reflectography, and a UV fluorescence multispectral image acquisition system. We present here the results of the techniques described, applied to the analysis of an important painting of the Italian Reinassance: `Madonna dei Fusi', attributed to Leonardo da Vinci.

  5. A psychoanalytic understanding of the desire for knowledge as reflected in Freud's Leonardo da Vinci and a memory of his childhood.

    Blass, Rachel B

    2006-10-01

    The author offers an understanding of the psychoanalytic notion of the desire for knowledge and the possibility of attaining it as it fi nds expression in Freud's Leonardo da Vinci and a memory of his childhood. This understanding has not been explicitly articulated by Freud but may be considered integral to psychoanalysis' Weltanschauung as shaped by Freud's legacy. It emerges through an attempt to explain basic shifts, contradictions, inconsistencies and tensions that become apparent from a close reading of the text of Leonardo. Articulating this implicit understanding of knowledge provides the grounds for a stance on epistemology that is integral to psychoanalysis and relevant to contemporary psychoanalytic concerns on this topic. This epistemology focuses on the necessary involvement of passion, rather than detachment, in the search for knowledge and views the psychoanalytic aim of self-knowledge as a derivative, and most immediate expression, of a broader and more basic human drive to know.

    Soranzo, Alessandro; Newberry, Michelle

    2016-10-04

    This paper discusses how the 'Uncatchable Smile' illusion in Leonardo da Vinci's La Bella Principessa portrait was discovered. Kemp and Cotte(1) described the expression of the Princess as ambiguous and "subtle to an inexpressible degree". A combination of three methods was used (inter-observation, structured interviews, and psychophysical experiments) to identify what may underlie this 'ambiguity'. The inter-observation and the structured interview methods were firstly applied to generate experimental hypotheses that were successively tested by a series of psychophysical experiments. The combination of these research methods minimizes the impact of the researcher's beliefs and biases in the development of the research design. It emerged that the ambiguity in La Bella Principessa is triggered by a change in the perceived level of contentment in her facial expression and that this perceptual change is attributable to a visual illusion relating to her mouth. Moreover, it was found that a similar effect can be observed in the Mona Lisa. As the smile in La Bella Principessa disappears as soon as the viewer tries to 'catch it', we named this visual illusion the 'Uncatchable Smile'. The elusive quality of the Mona Lisa's smile(2) is probably why the portrait is so famous, and so the existence of a similar ambiguity in a portrait painted by Leonardo prior to the Mona Lisa is even more interesting.

    The interpretation of the heart as a mechanical engine dates back to the teachings of Leonardo da Vinci, who was the first to apply the laws of mechanics to the function of the heart. Similar to any mechanical engine, whose performance is proportional to the power generated with respect to weight, the left ventricle can be viewed as a power generator whose performance can be related to left ventricular mass. Stress echocardiography may provide valuable information on the relationship between cardiac performance and recruited left ventricular mass that may be used in distinguishing between adaptive and maladaptive left ventricular remodeling. Peak power output-to-mass, obtained during exercise or pharmacological stress echocardiography, is a measure that reflects the number of watts that are developed by 100 g of left ventricular mass under maximal stimulation. Power output-to-mass may be calculated as left ventricular power output per 100 g of left ventricular mass: 100× left ventricular power output divided by left ventricular mass (W/100 g). A simplified formula to calculate power output-to-mass is as follows: 0.222 × cardiac output (l/min) × mean blood pressure (mmHg)/left ventricular mass (g). When the integrity of myocardial structure is compromised, a mismatch becomes apparent between maximal cardiac power output and left ventricular mass; when this occurs, a reduction of the peak power output-to-mass index is observed.

Rarely has the interest of scholars concentrated on architectural proportions (Pedretti 1978; Schofield 1991; more frequently scholars have tried to ‘ridurre in proportione’ the plans or to arrange the sketches by Leonardo into real dimensions (for example, Guillaume and Kübacher (1987.

    The da Vinci surgical system was developed by Intuitive Surgical Inc. in the United States as an endoscopic surgical device to assist remote control surgeries. In 1998, the Da Vinci system was first used for cardiothoracic procedures. Currently a combination of robot-assisted internal thoracic artery harvest together with coronary artery bypass grafting (CABG) through a mini-incision (ThoraCAB) or totally endoscopic procedures including anastomoses under robotic assistance (TECAB) are being conducted for the treatment of coronary artery diseases. With the recent advances in catheter interventions, hybrid procedures combining catheter intervention with ThoraCAB or TECAB are anticipated in the future.On the other hand, with the decrease in number of coronary artery bypass surgeries, the share of valvular surgeries is expected to increase in the future. Among them, mitral valvuloplasty for mitral regurgitation is anticipated to be conducted mainly by low-invasive procedures, represented by minimally invasive cardiac surgery( MICS) and robot-assisted surgery. Apart from the intrinsic good surgical view, robotic-assisted systems offer additional advantages of the availability of an amplified view and the easy to observe the mitral valve in the physiological position. Thus, robotic surgical surgeries that make complicated procedures easier are expected to accomplish further developments in the future. Furthermore, while the number of surgeries for atrial septal defects has decreased dramatically following the widespread use of Amplatzer septal occluder, robotic surgery may become a good indication for cases in which the Amplatzer device is not indicated. In Japan, clinical trial of the da Vinci robotic system for heart surgeries has been completed. Statutory approval of the da Vinci system for mitral regurgitation and atrial septal defects is anticipated in the next few years.

    We usually display a laid-back approach to medical jargon throughout our theatre work. The word 'perioperative' is built from the Greek word 'peri' (around) and the Latin 'operari' (to work). Latin and Greek became the prefixed language of choice for Leonardo da Vinci, and his research was pivotal in determining the way in which surgical procedures are documented. Ancient manuscripts aided the unfolding of the secrets of anatomy, and Leonardo revealed that art was the key in expressive detailed explanation.

    In conventional stereopsis, the depth between two objects is computed based on the retinal disparity in the position of matching points in the two eyes. When an object is occluded by another object in the scene, so that it is visible only in one eye, its retinal disparity cannot be computed. Nakayama and Shimojo (1990) found that a precept of quantitative depth between the two objects could still be established for such stimuli and proposed that this precept is based on the constraints imposed by occlusion geometry. They named this and other occlusion-based depth phenomena "da Vinci stereopsis." Subsequent research found quantitative depth based on occlusion geometry in several other classes of stimuli grouped under the term da Vinci stereopsis. However, Nakayama and Shimojo's findings were later brought into question by Gillam, Cook, and Blackburn (2003), who suggested that quantitative depth in their stimuli was perceived based on conventional disparity. In order to understand whether da Vinci stereopsis relies on one type of mechanism or whether its function is stimulus dependent we examine the nature and source of depth in the class of stimuli used by Nakayama and Shimojo (1990). We use three different psychophysical and computational methods to show that the most likely source for depth in these stimuli is occlusion geometry. Based on these experiments and previous data we discuss the potential mechanisms responsible for processing depth from monocular features in da Vinci stereopsis.

  6. DaVinci's Mona Lisa entering the next dimension.

    For several of Leonardo da Vinci's paintings, such as The Virgin and Child with St Anne or the Mona Lisa, there exist copies produced by his own studio. In case of the Mona Lisa, a quite exceptional, rediscovered studio copy was presented to the public in 2012 by the Prado Museum in Madrid. Not only does it mirror its famous counterpart superficially; it also features the very same corrections to the lower layers, which indicates that da Vinci and the 'copyist' must have elaborated their panels simultaneously. On the basis of subjective (thirty-two participants estimated painter-model constellations) as well as objective data (analysis of trajectories between landmarks of both paintings), we revealed that both versions differ slightly in perspective. We reconstructed the original studio setting and found evidence that the disparity between both paintings mimics human binocular disparity. This points to the possibility that the two Giocondas together might represent the first stereoscopic image in world history.

    Full Text Available This paper discusses the problem of virtual lab capabilities in the e-learning. Using combination of web conferencing and "virtual labs" capabilities, a new quality distance learning teaching is now in preparation and will be included in the course teaching to produce interactive, online simulations for the natural gas engineering studies. The activities are designed to enhance the existing curriculum and to include online assessments. A special care is devoted to the security problem between a server and a client computer. Several examples of the virtual labs related to the PVT thermodynamics, fluid flow, the natural gas well-testing, and thev gas network flow are prepared and tested. A major challenge for the 'CELGAS' system is in managing the delicate balance between the student collaboration and the isolation. Students may be encouraged to collaborate and work with each other, simulating their exploration of the lab material.

    n 1998, a little known picture was sold for a modest sum in a New York saleroom and in so doing attracted the attention of the art world. Painstaking analysis by the Oxford art historian Martin Kemp and others, revealed it to be the work of Leonardo Da Vinci (Kemp & Cotte, 2010, Hodder & Stoughton). Given the considerable interest in La Bella Principessa, it is perhaps surprising now to suggest that it may contain an illusion.

    The rapid adoption of robotic assisted surgery challenges the pace at which adequate robotic training can occur due to access limitations to the da Vinci robot. Thirty medical students completed a randomized controlled trial evaluating whether the Raven robot could be used as an alternative training tool for the Fundamentals of Laparoscopic Surgery (FLS) block transfer task on the da Vinci robot. Two groups, one trained on the da Vinci and one trained on the Raven, were tested on a criterion FLS block transfer task on the da Vinci. After robotic FLS block transfer proficiency training there was no statistically significant difference between path length (p=0.39) and economy of motion scores (p=0.06) between the two groups, but those trained on the da Vinci did have faster task times (p=0.01). These results provide evidence for the value of using the Raven robot for training prior to using the da Vinci surgical system for similar tasks.

  5. A computational theory of da Vinci stereopsis.

    2014-06-09

    In binocular vision, occlusion of one object by another gives rise to monocular occlusions—regions visible only in one eye. Although binocular disparities cannot be computed for these regions, monocular occlusions can be precisely localized in depth and can induce the perception of illusory occluding surfaces. The phenomenon of depth perception from monocular occlusions, known as da Vinci stereopsis, is intriguing, but its mechanisms are not well understood. We first propose a theory of the mechanisms underlying da Vinci stereopsis that is based on the psychophysical and computational literature on monocular occlusions. It postulates, among other principles, that monocular areas are detected explicitly, and depth from occlusions is calculated based on constraints imposed by occlusion geometry. Next, we describe a biologically inspired computational model based on this theory that successfully reconstructs depth in a large range of stimuli and produces results similar to those described in the psychophysical literature. These results demonstrate that the proposed neural architecture could underpin da Vinci stereopsis and other stereoscopic percepts.

At 1985 the robot PUMA 560 was employed to introduce a needle inside the brain. Later on, they were designed surgical robots like World First, Robodoc, Gaspar o Acrobot, Zeus, AESOP, Probot o PAKI-RCP. At 2000 the FDA approved the da Vinci Surgical System (Intuitive Surgical Inc, Sunnyvale, CA, USA), a very sophisticated robot to assist surgeons. Currently urological procedures like prostatectomy, cystectomy and nephrectomy are performed with the da Vinci, so urology has become a very suitable speciality to robotic surgery.

  20. The role of transparency in da Vinci stereopsis.

    Science.gov (United States)

    Zannoli, Marina; Mamassian, Pascal

    2011-10-15

    The majority of natural scenes contains zones that are visible to one eye only. Past studies have shown that these monocular regions can be seen at a precise depth even though there are no binocular disparities that uniquely constrain their locations in depth. In the so-called da Vinci stereopsis configuration, the monocular region is a vertical line placed next to a binocular rectangular occluder. The opacity of the occluder has been mentioned to be a necessary condition to obtain da Vinci stereopsis. However, this opacity constraint has never been empirically tested. In the present study, we tested whether da Vinci stereopsis and perceptual transparency can interact using a classical da Vinci configuration in which the opacity of the occluder varied. We used two different monocular objects: a line and a disk. We found no effect of the opacity of the occluder on the perceived depth of the monocular object. A careful analysis of the distribution of perceived depth revealed that the monocular object was perceived at a depth that increased with the distance between the object and the occluder. The analysis of the skewness of the distributions was not consistent with a double fusion explanation, favoring an implication of occlusion geometry in da Vinci stereopsis. A simple model that includes the geometry of the scene could account for the results. In summary, the mechanism responsible to locate monocular regions in depth is not sensitive to the material properties of objects, suggesting that da Vinci stereopsis is solved at relatively early stages of disparity processing.

    Full Text Available Following the discovery of discoloration on some pages of the Atlantic Codex (AC of Leonardo da Vinci kept in the Biblioteca Ambrosiana in Milan, some investigations have been carried out to verify the presence of microorganisms, such as bacteria and fungi. To verify the presence of microorganisms a noninvasive method of sampling has been used that was efficient and allowed us to highlight the microbial facies of the material that was examined using conventional microbiological techniques. The microclimatic conditions in the storage room as well as the water content of the volume were also assessed. The combined observations allowed the conclusion that the discoloration of suspected biological origin on some pages of AC is not related to the presence or current attack of microbial agents.

    Robotic surgery is the newst technologic option in urology. To understand how new robots work is interesting to know their history. The desire to design machines imitating humans continued for more than 4000 years. There are references to King-su Tse (clasic China) making up automaton at 500 a. C. Archytas of Tarentum (at around 400 a.C.) is considered the father of mechanical engineering, and one of the occidental robotics classic referents. Heron of Alexandria, Hsieh-Fec, Al-Jazari, Roger Bacon, Juanelo Turriano, Leonardo da Vinci, Vaucanson o von Kempelen were robot inventors in the middle age, renaissance and classicism. At the XIXth century, automaton production underwent a peak and all engineering branches suffered a great development. At 1942 Asimov published the three robotics laws, based on mechanics, electronics and informatics advances. At XXth century robots able to do very complex self governing works were developed, like da Vinci Surgical System (Intuitive Surgical Inc, Sunnyvale, CA, USA), a very sophisticated robot to assist surgeons.

    2014-05-01

    Robot-assisted surgery using the da Vinci surgical system has attracted attention because of excellent operability without shaking by joint forceps under the clear vision of a three-dimensional high-definition camera in lung cancer surgery. Although this form of advanced medical care is not yet approved for insurance coverage, it is at the stage of clinical research and expected to be useful in hilar exposure, lymph node dissection, and suturing of the lung parenchyma or bronchus. Lung cancer surgery with the da Vinci system has the advantage of combining thoracotomy and minimally invasive surgery in video-assisted thoracic surgery. However, safety management, education, and significant cost are problems to be resolved. Several important issues such as sharing knowledge and technology of robotic surgery, education, training, development of new instruments, and acquisition of advanced medical insurance are discussed for the future development of robotic surgical systems.

    This study aims (1) to investigate the feasibility of robot-assisted penetrating keratoplasty (PK) using the new Da Vinci Xi Surgical System and (2) to report what we believe to be the first use of this system in experimental eye surgery. Robot-assisted PK procedures were performed on human corneal transplants using the Da Vinci Xi Surgical System. After an 8-mm corneal trephination, four interrupted sutures and one 10.0 monofilament running suture were made. For each procedure, duration and successful completion of the surgery as well as any unexpected events were assessed. The depth of the corneal sutures was checked postoperatively using spectral-domain optical coherence tomography (SD-OCT). Robot-assisted PK was successfully performed on 12 corneas. The Da Vinci Xi Surgical System provided the necessary dexterity to perform the different steps of surgery. The mean duration of the procedures was 43.4 ± 8.9 minutes (range: 28.5-61.1 minutes). There were no unexpected intraoperative events. SD-OCT confirmed that the sutures were placed at the appropriate depth. We confirm the feasibility of robot-assisted PK with the new Da Vinci Surgical System and report the first use of the Xi model in experimental eye surgery. Operative time of robot-assisted PK surgery is now close to that of conventional manual surgery due to both improvement of the optical system and the presence of microsurgical instruments. Experimentations will allow the advantages of robot-assisted microsurgery to be identified while underlining the improvements and innovations necessary for clinical use.

    Intraoperative tracking of laparoscopic instruments is a prerequisite to realize further assistance functions. Since endoscopic images are always available, this sensor input can be used to localize the instruments without special devices or robot kinematics. In this paper, we present an image-based markerless 3D tracking of different da Vinci instruments in near real-time without an explicit model. The method is based on different visual cues to segment the instrument tip, calculates a tip point and uses a multiple object particle filter for tracking. The accuracy and robustness is evaluated with in vivo data.

  6. UNFOLDING LEONARDO DA VINCI’S GLOBE (AD 1504 TO REVEAL ITS HISTORICAL WORLD MAP

    Directory of Open Access Journals (Sweden)

    G. J. Verhoeven

    2017-08-01

    Full Text Available This paper reports in detail on the image-based modelling and unwrapping approach used to create a two-dimensional projected map of an astonishing ostrich egg globe from AD 1504. This miniature egg globe is not only the oldest extant engraved globe, but it is also the oldest post-Columbian globe of the world and the first ever to depict Newfoundland and many other territories. The intention of digitally recording the surface geometry and colour of this unique artefact was to portray the original layout of the world map used by the Florentine Renaissance artist to make this globe. In addition, it was expected to substantiate iconographical details, which are hard to study at its scale of 1:80,000,000. The ostrich egg globe is the prototype of the Lenox Globe kept at the New York Public Library. The latter is very beneficial to examine how the egg globe looked like before being glued together at its equator. On the other hand, unfolding the map engraved in the ostrich egg halves enables a more detailed study of the remarkable details visible on both globes, since the engravings on the quasi-white egg surface are much easier to discern than those of the highly reflective red copper Lenox Globe. Finally, a detailed study of the unwrapped 3D surface is essential to learn more about the world vision of its creator and the incredible efforts that went into making this globe. Thanks to some particular pictographic details as well as the way in which the engravings are applied (by a left-handed person, the globe artist can be identified as Leonardo da Vinci.

    Transoral robotic surgery, performed with the da Vinci surgical system (da Vinci), is a surgical approach for benign and malignant lesions of the oral cavity and laryngopharynx. It provides several unique advantages, which include a 3-dimensional magnified view and ability to see and work around curves or angles. However, the current da Vinci surgical system does not provide haptic feedback. This is problematic because the potential risks specific to the transoral use of the da Vinci include tooth injury, mucosal laceration, ocular injury and mandibular fracture. To assess the potential for intraoperative injuries, we measured the load of the endoscope and the instrument of the da Vinci Si surgical system. We pressed the endoscope and instrument of the da Vinci Si against Load cell six times each and measured the dynamic load and the time-to-maximum load. We also struck the da Vinci Si endoscope and instrument against the Load cell six times each and measured the impact load. The maximum dynamic load was 7.27 ± 1.31 kg for the endoscope and 1.90 ± 0.72 for the instrument. The corresponding time-to-maximum loads were 1.72 ± 0.22 and 1.29 ± 0.34 s, but the impact loads were significantly lower than the dynamic load. It remains possible that a major load is exerted on adjacent structures by continuous contact with the endoscope and instrument of da Vinci Si. However, there is a minor delay in reaching the maximum load. Careful monitoring by an on-site assistant may, therefore, help prevent contiguous injury.

    The da Vinci Xi Surgical System (Intuitive Surgical Inc., Sunnyvale, CA, USA) has been released in 2014 to facilitate minimally invasive surgery. Novel features are targeted towards facilitating complex multi-quadrant procedures, but data is scarce so far. Perioperative data of patients who underwent robotic general surgery with the da Vinci Xi system within the first 6 month after installation were collected and analyzed. The gastric bypass procedures performed with the da Vinci Xi Surgical System were compared to an equal amount of the last procedures with the da Vinci Si Surgical System. Thirty-one foregut (28 Roux-en-Y gastric bypasses), 6 colorectal procedures and 1 revisional biliary procedure were performed. The mean operating room (OR) time was 221.8 (±69.0) minutes for gastric bypasses and 306.5 (±48.8) for colorectal procedures with mean docking time of 9.4 (±3.8) minutes. The gastric bypass procedure was transitioned from a hybrid to a fully robotic approach. In comparison to the last 28 gastric bypass procedures performed with the da Vinci Si Surgical System, the OR time was comparable (226.9 versus 230.6 min, p = 0.8094), but the docking time significantly longer with the da Vinci Xi Surgical System (8.5 versus 6.1 min, p = 0.0415). All colorectal procedures were performed with a single robotic docking. No intraoperative and two postoperative complications occurred. The da Vinci Xi might facilitate single-setups of totally robotic gastric bypass and colorectal surgeries. However, further comparable research is needed to clearly determine the significance of this latest version of the da Vinci Surgical System.

  11. Pychoanalysis and art, Freud and Leonardo.

    Science.gov (United States)

    Blum, H P

    2001-01-01

    Freud was the first to apply psychoanalysis to art, choosing for his subject the life and work of Leonardo da Vinci. Observing Leonardo's partly fused image of the Virgin and St. Anne, he inferred that the artist had depicted his two mothers, his biological mother and his stepmother. This very early analytic discourse on parent loss and adoption changed the course of the interpretation of art. Freud explored the psychology of art, the artist, and aesthetic appreciation. Confronting the age-old enigma of the Mona Lisa, he proposed a daring solution to the riddle of the sphinxlike smile of this icon of art. His paper prefigures concepts of narcissism, homosexuality, parenting, and sublimation. Lacking modern methodology and theory, Freud's pioneering insights overshadow his naive errors. In this fledgling inquiry, based on a childhood screen memory and limited knowledge of Leonardo's artistic and scientific contributions, Freud identified with this Renaissance genius in his own self-analytic and creative endeavor.

  15. In search of Leonardo: computer-based facial image analysis of Renaissance artworks for identifying Leonardo as subject

    Tyler, Christopher W.; Smith, William A. P.; Stork, David G.

    2012-03-01

    One of the enduring mysteries in the history of the Renaissance is the adult appearance of the archetypical "Renaissance Man," Leonardo da Vinci. His only acknowledged self-portrait is from an advanced age, and various candidate images of younger men are difficult to assess given the absence of documentary evidence. One clue about Leonardo's appearance comes from the remark of the contemporary historian, Vasari, that the sculpture of David by Leonardo's master, Andrea del Verrocchio, was based on the appearance of Leonardo when he was an apprentice. Taking a cue from this statement, we suggest that the more mature sculpture of St. Thomas, also by Verrocchio, might also have been a portrait of Leonardo. We tested the possibility Leonardo was the subject for Verrocchio's sculpture by a novel computational technique for the comparison of three-dimensional facial configurations. Based on quantitative measures of similarities, we also assess whether another pair of candidate two-dimensional images are plausibly attributable as being portraits of Leonardo as a young adult. Our results are consistent with the claim Leonardo is indeed the subject in these works, but we need comparisons with images in a larger corpora of candidate artworks before our results achieve statistical significance.

  20. Color constrains depth in da Vinci stereopsis for camouflage but not occlusion.

    Science.gov (United States)

    Wardle, Susan G; Gillam, Barbara J

    2013-12-01

    Monocular regions that occur with binocular viewing of natural scenes can produce a strong perception of depth--"da Vinci stereopsis." They occur either when part of the background is occluded in one eye, or when a nearer object is camouflaged against a background surface in one eye's view. There has been some controversy over whether da Vinci depth is constrained by geometric or ecological factors. Here we show that the color of the monocular region constrains the depth perceived from camouflage, but not occlusion, as predicted by ecological considerations. Quantitative depth was found in both cases, but for camouflage only when the color of the monocular region matched the binocular background. Unlike previous reports, depth failed even when nonmatching colors satisfied conditions for perceptual transparency. We show that placing a colored line at the boundary between the binocular and monocular regions is sufficient to eliminate depth from camouflage. When both the background and the monocular region contained vertical contours that could be fused, some observers appeared to use fusion, and others da Vinci constraints, supporting the existence of a separate da Vinci mechanism. The results show that da Vinci stereopsis incorporates color constraints and is more complex than previously assumed.

    The da Vinci system (da Vinci Surgical System; Intuitive Surgical Inc.) has rapidly developed in several years from the S system to the Si system and now the Xi System. To investigate the surgical feasibility and to provide workflow guidance for the newly released system, we used the new da Vinci Xi system for transoral robotic surgery (TORS) on a cadaveric specimen. Bilateral supraglottic partial laryngectomy, hypopharyngectomy, lateral oropharyngectomy, and base of the tongue resection were serially performed in search of the optimal procedures with the new system. The new surgical robotic system has been upgraded in all respects. The telescope and camera were incorporated into one system, with a digital end-mounted camera. Overhead boom rotation allows multiquadrant access without axis limitation, the arms are now thinner and longer with grabbing movements for easy adjustments. The patient clearance button dramatically reduces external collisions. The new surgical robotic system has been optimized for improved anatomic access, with better-equipped appurtenances. This cadaveric study of TORS offers guidance on the best protocol for surgical workflow with the new Xi system leading to improvements in the functional results of TORS.

  3. A strange bridge by Leonardo

    Huylebrouck, Dirk

    2013-01-01

    On folio 855 recto of the Codex Atlanticus, Leonardo da Vinci drew three 'easily movable' bridges, but one of them is enigmatic: all 'replicas' in Leonardo museums and exhibitions come as a surprise, to say the least, to any engineer or architect whose attention is drawn to it. This is the case for models in Amboise (France), Chicago and Portland (USA), Florence (Italy) and for the one of the traveling exhibition by the Australian company 'Grande Exhibitions' that already visited 40 major cities in the world. All 'replicas' of the bridge model attributed to Leonardo have pillars standing on the deck of the bridge, while the deck is suspended by cables attached on these pillars. At first sight this problem does not catch the attention of the observer, as the bridge seems to be a mixed form of a beam and a suspension bridge, but it was not overlooked by my colleague architect-engineer Dr. Laurens Luyten (Gent, Belgium). Yet, after a TV-interview in Brussels so much pressure was exerted by some of the museum col...

    Endoscopic surgery for treatment of thyroid and parathyroid pathologies is increasingly gaining attention. The da Vinci system has already been widely used in different fields of medicine and quite recently in thyroid and parathyroid surgery. Herein, we report about modifications of the transaxillary approach in endoscopic surgery of thyroid and parathyroid gland pathologies using the da Vinci system. 16 patients suffering from struma nodosa in 14 cases and parathyroid adenomas in two cases were treated using the da Vinci system at the ENT Department of Homburg/Saar University and in cooperation with the Department of General Surgery in New Sant'Agostino Hospital, Modena/Italy. Two different retractors, endoscopic preparation of the access and three different incision modalities were used. The endoscopic preparation of the access allowed us to have a better view during preparation and reduced surgical time compared to the use of a headlamp. To introduce the da Vinci instruments at the end of the access preparation, the skin incisions were over the axilla with one incision in eight patients, two incisions in four patients and three incisions in a further four patients. The two and three skin incisions modality allowed introduction of the da Vinci instruments without arm conflicts. The use of a new retractor (Modena retractor) compared to a self-developed retractor made it easier during the endoscopic preparation of the access and the reposition of the retractor. The scar was hidden in the axilla and independent of the incisions selected, the cosmetic findings were judged by the patients to be excellent. The neurovascular structures such as inferior laryngeal nerve, superior laryngeal nerve and vessels, as well as the different pathologies, were clearly 3D visualized in all 16 cases. No paralysis of the vocal cord was observed. All patients had a benign pathology in their histological examination. The endoscopic surgery of the thyroid and parathyroid gland can be

    Robot-assisted laparoscopic radical prostatectomy (RALRP) using the da Vinci surgical system is the current state-of-the-art treatment option for clinically confined prostate cancer. Given the limited field of view of the surgical site in RALRP, several groups have proposed the integration of transrectal ultrasound (TRUS) imaging in the surgical workflow to assist with accurate resection of the prostate and the sparing of the neurovascular bundles (NVBs). We previously introduced a robotic TRUS manipulator and a method for automatically tracking da Vinci surgical instruments with the TRUS imaging plane, in order to facilitate the integration of intraoperative TRUS in RALRP. Rapid and automatic registration of the kinematic frames of the da Vinci surgical system and the robotic TRUS probe manipulator is a critical component of the instrument tracking system. In this paper, we propose a fully automatic registration technique based on automatic 3-D TRUS localization of robot instrument tips pressed against the air-tissue boundary anterior to the prostate. The detection approach uses a multiscale filtering technique to identify and localize surgical instrument tips in the TRUS volume, and could also be used to detect other surface fiducials in 3-D ultrasound. Experiments have been performed using a tissue phantom and two ex vivo tissue samples to show the feasibility of the proposed methods. Also, an initial in vivo evaluation of the system has been carried out on a live anaesthetized dog with a da Vinci Si surgical system and a target registration error (defined as the root mean square distance of corresponding points after registration) of 2.68 mm has been achieved. Results show this method's accuracy and consistency for automatic registration of TRUS images to the da Vinci surgical system.

    As a prototype of the antiplague costume can be considered a special clothing, which physicians in medieval Europe wear for protection in plague nidus. Inventor of the first antiplague costume is considered to be a French doctor Charles de Lorme (1619). Much later, in 1878, a Russian professor Pashutin V V offered to use a costume, which looked like a hermetically sealed "bag" with a special breathing device aimed at protection of medical staff. Later, professor O.I. Dogel's respirator became well-known (1889). At the beginning of 20th century as part of the antiplague costume was used a charcoal filter mask, invented by Zelinsky N.D. Requirements to order the use of modern means of individual protection when working in nidus of especially dangerous infections identified sanitary-epidemiological rules, which reflect issues of laboratory workers working and protective clothing, respiratory protection, and view, especially operation, the procedure of putting on, removing and disinfecting antiplague costumes, pneumocostumes, pneumohelmets, isolation suits, gas-protection boxes, etc.

    Virtual reality simulators are increasingly used to gain robotic surgical skills. This study compared use of the da Vinci Surgical Skills Simulator (dVSSS) to the standard da Vinci (SdV) robot for skills acquisition in a prospective randomized study. Residents from urology, gynecology, and general surgery programs performed three virtual reality tasks (thread the ring, ring rail, and tubes) on the dvSSS. Participants were then randomized to one of the two study groups (dVSSS and SdV). Each participant then practiced on either the dVSSS or the SdV (depending on randomization) for 30 min per week over a 4-week time period. The dVSSS arm was not permitted to practice ring rail (due to no similar practice scenario available for the SdV group). Following 4 weeks of practice, participants performed the same three virtual reality tasks and the results were recorded and compared to baseline. Overall and percent improvement were recorded for all participants from pre-test to post-test. Two-way ANOVA analyses were used to compare the dVSSS and SdV groups and three tasks. Initially, 30 participants were identified and enrolled in the study. Randomization resulted in 15 participants in each arm. During the course of the study, four participants were unable to complete all tasks and practice sessions and were, therefore, excluded. This resulted in a total of 26 participants (15 in the dVSSS group and 11 in the SdV group) who completed the study. Overall total improvement score was found to be 23.23 and 23.48 for the SdV and dVSSS groups, respectively (p = 0.9245). The percent improvement was 60 and 47 % for the SdV and dVSSS groups respectively, which was a statistically significant difference between the two groups and three tasks. Practicing on the standard da Vinci is comparable to practicing on the da Vinci simulator for acquiring robotic surgical skills. In spite of several potential advantages, the dVSSS arm performed no better than the SdV arm in the final

    Transoral thyroid surgery allows the surgeon to conceal incisions within the oral cavity without significantly increasing the amount of required dissection. TORT provides an ideal scarless, midline access to the thyroid gland and bilateral central neck compartments. This approach, however, presents multiple technical challenges. Herein, we present our experience using the latest generation robotic surgical system to accomplish transoral robotic thyroidectomy (TORT). In two human cadavers, the da Vinci Xi surgical system (Intuitive Surgical, Sunnyvale, CA, USA) was used to complete TORT. Total thyroidectomy and bilateral central neck dissection was successfully completed in both cadavers. The da Vinci Xi platform offered several technologic advantages over previous robotic generations including overhead docking, narrower arms, and improved range of motion allowing for improved execution of previously described TORT techniques.

    Camera positioning is critical for all telerobotic surgical systems. Inadequate visualization of the remote site can lead to serious errors that can jeopardize the patient. An autonomous camera algorithm has been developed on a medical robot (da Vinci) simulator. It is found to be robust in key scenarios of operation. This system behaves with predictable and expected actions for the camera arm with respect to the tool positions. The implementation of this system is described herein. The simulation closely models the methodology needed to implement autonomous camera control in a real hardware system. The camera control algorithm follows three rules: (1) keep the view centered on the tools, (2) keep the zoom level optimized such that the tools never leave the field of view, and (3) avoid unnecessary movement of the camera that may distract/disorient the surgeon. Our future work will apply this algorithm to the real da Vinci hardware.

    Robot-assisted laparoscopic surgery is often taught with the surgical mentor at the surgeon console and the trainee at the patient's bedside. The da Vinci dual console (Intuitive Surgical, Sunnyvale, California) allows a surgical mentor to teach with both the mentor and the trainee working at a surgeon console simultaneously. The purpose of this study is to evaluate the effectiveness of the dual console versus the single console for teaching medical students robotic tasks. Forty novice medical students were randomized to either the da Vinci single-console or dual-console group and were taught 4 knot-tying techniques by a surgical mentor. The students were timed while performing the tasks. No statistically significant differences in mean task times were observed between the single- and dual-console groups: interrupted stitch with a 2-handed knot (300 seconds for single vs 294 seconds for dual, P=.59), interrupted stitch with a 1-handed knot (198 seconds for single vs 212 seconds for dual, P=.88), figure-of-8 stitch with a 2-handed knot (261 seconds for single vs 219 seconds for dual, P=.20), and figure-of-8 stitch with a 1-handed knot (200 seconds for single vs 199 seconds for dual, P=.53). No significant difference was observed in performance time when teaching knot-tying techniques to medical students using the da Vinci dual console compared with the single console. More research needs to be performed on the utility of the da Vinci dual console in surgical training.

    The goal of this cadaver study was to evaluate the feasibility and safety of da Vinci robot-assisted keyhole neurosurgery. Several keyhole craniotomies were fashioned including supraorbital subfrontal, retrosigmoid and supracerebellar infratentorial. In each case, a simple durotomy was performed, and the flap was retracted. The da Vinci surgical system was then used to perform arachnoid dissection towards the deep-seated intracranial cisterns. It was not possible to simultaneously pass the 12-mm endoscope and instruments through the keyhole craniotomy in any of the approaches performed, limiting visualization. The articulated instruments provided greater dexterity than existing tools, but the instrument arms could not be placed in parallel through the keyhole craniotomy and, therefore, could not be advanced to the deep cisterns without significant clashing. The da Vinci console offered considerable ergonomic advantages over the existing operating room arrangement, allowing the operating surgeon to remain non-sterile and seated comfortably throughout the procedure. However, the lack of haptic feedback was a notable limitation. In conclusion, while robotic platforms have the potential to greatly enhance the performance of transcranial approaches, there is strong justification for research into next-generation robots, better suited to keyhole neurosurgery.

  6. Da Vinci© Skills Simulator™: is an early selection of talented console surgeons possible?

    2016-12-01

    To investigate whether the learning curve of robotic surgery simulator training depends on the probands' characteristics, such as age and prior experience, we conducted a study of six distinct proband groups, using the da Vinci Skills Simulator: experienced urological robotic surgeons, surgeons with experience as da Vinci tableside assistants, urological surgeons with laparoscopic experience, urological surgeons without laparoscopic experience, and complete novices aged 25 and younger and 40 and older. The results showed that all experienced robotic surgeons reached expert level (>90 %, as defined previously in the literature) within the first three repetitions and remained on a high level of performance. All other groups performed worse. Tableside assistants, laparoscopically experienced surgeons, and younger novices showed a better performance in all exercises than surgeons without laparoscopic experience and older novices. A linear mixed-effects model analysis demonstrated no significant difference in learning curves between proband groups in all exercises except the RW1 exercise for the younger proband group. In summary, we found that performance in robotic surgery, measured by performance scores in three virtual simulator modules using the EndoWrist techniques, was dependent on age and prior experience with robotic and laparoscopic surgery. However, and most importantly, the learning curve was not significantly affected by these factors. This suggests that the da Vinci Skills Simulator™ is a useful practice tool for everyone learning or performing robotic surgery, and that early selection of talented surgeons is neither possible nor necessary.

    The latest generation Da Vinci(®) Xi™ Surgical System Robot released has not been evaluated to date in transoral surgery for head and neck cancers. We report here the 1-year results of a non-randomized phase II multicentric prospective trial aimed at assessing its feasibility and technical specificities. Our primary objective was to evaluate the feasibility of transoral robotic surgery using the da Vinci(®) Xi™ Surgical System Robot. The secondary objective was to assess peroperative outcomes. Twenty-seven patients, mean age 62.7 years, were included between May 2015 and June 2016 with tumors affecting the following sites: oropharynx (n = 21), larynx (n = 4), hypopharynx (n = 1), parapharyngeal space (n = 1). Eighteen patients were included for primary treatment, three for a local recurrence, and six for cancer in a previously irradiated field. Three were reconstructed with a FAMM flap and 6 with a free ALT flap. The mean docking time was 12 min. "Chopsticking" of surgical instruments was very rare. During hospitalization following surgery, 3 patients experienced significant bleeding between day 8 and 9 that required surgical transoral hemostasis (n = 1) or endovascular embolization (n = 2). Transoral robotic surgery using the da Vinci(®) Xi™ Surgical System Robot proved feasible with technological improvements compared to previous generation surgical system robots and with a similar postoperative course. Further technological progress is expected to be of significant benefit to the patients.

    2016-08-19

    The da Vinci Xi robot has been introduced as the successor to the Si platform. The promise of the Xi is to open the door to new surgical procedures. For robotic-assisted radical prostatectomy (RARP)/pelvic surgery, the potential is better vision and longer instruments. How has the Xi impacted on operative and pathological parameters as indicators of surgical performance? This is a comparison of an initial series of 42 RARPs with the Xi system in 2015 with a series using the Si system immediately before Xi uptake in the same calendar year, and an Si series by the same surgeon synchronously as the Xi series using operative time, blood loss, and positive margins as surrogates of surgical performance. Subjectively and objectively, there is a learning curve to Xi uptake in longer operative times but no impact on T2 positive margins which are the most reflective single measure of RARP outcomes. Subjectively, the vision of the Xi is inferior to the Si system, and the integrated diathermy system and automated setup are quirky. All require experience to overcome. There is a learning curve to progress from the Si to Xi da Vinci surgical platforms, but this does not negatively impact the outcome.

    In dieser Studie wurde untersucht ob in einem typischen OP-Aufbau mit dem da Vinci® Telemanipulator elektromagnetisches Tracking für die Realisation eines Navigationssystems eingesetzt werden kann. Hierfür wurde in einem realen OP-Aufbau untersucht, wie stark metallische und ferromagnetisch wirksame Objekte wie Operationstisch und Telemanipulator das elektromagnetische Feld des Trackingsystems beeinflussen. Die Ergebnisse zeigen, dass der Telemanipulator nur unwesentlich die Störung des Magnetfeldes durch den OP-Tisch verstärkt. Insbesondere die Bewegung der Instrumente im Trackingvolumen verursachte keine zusätzliche relevante Störung des Magnetfeldes. Bei Begrenzung des Trackingvolumens auf eine Länge von 190 mm, Höhe von 200mm und Breite von 400 mm war der maximale Fehler in diesem Bereich an allen Messpunkten kleiner 10 mm. Der Einsatz von elektromagnetischem Tracking für die Navigation mit dem da Vinci® Surgical System ist somit in einem begrenzten Arbeitsvolumen mit hinreichender Genauigkeit möglich.

    The aims of this study were to compare the perioperative outcomes of da Vinci Xi to Si during robotic-assisted partial nephrectomy (RAPN) and to discuss the feasibility of our novel port placement scheme for the da Vinci Xi platform, to overcome the existing kinetic and technical difficulties we faced with the linear port placement in patients with a small body habitus. A retrospective data analysis of patients who underwent RPN using da Vinci Xi (n = 18) was carried out. The outcomes of the Xi group were compared with the Si group (n = 18) selected using a case-matched methodology. For da Vinci Xi, we applied the universal linear port placement in 12 patients and our modified port placement in the remaining 6 patients. The Xi group had a shorter mean docking time of 17.8 ± 2.6 min compared to the Si group of 20.5 ± 2.1 min (p = 0.002); otherwise, no significant difference was present with regard to the remaining perioperative variables (p > 0.05). The modified Xi port placement had a shorter mean console time of 70.8 ± 9.7 min compared to the universal linear port placement of 89.3 ± 17.2 min (p = 0.03). Moreover, it provided a broader field of vision with excellent robotic arms movement, minimizing collisions and allowing an easier and comfortable surgical assist. Da Vinci Xi appears to be feasible and safe during RPN with similar outcomes to Si. The novel Xi port placement makes surgery easier in patients with low BMI.

    The first robotic simple hysterectomy was performed more than 10 years ago. These days, robotic-assisted hysterectomy is accepted as an alternative surgical approach and is applied both in benign and malignant surgical entities. The two important points that should be taken into account to optimize postoperative outcomes in the early period of a surgeon's training are how to achieve optimal oncological and functional results. Overcoming any technical challenge, as with any innovative surgical method, leads to an improved surgical operation timewise as well as for patients' safety. The standardization of the technique and recognition of critical anatomical landmarks are essential for optimal oncological and clinical outcomes on both simple and radical robotic-assisted hysterectomy. Based on our experience, our intention is to present user-friendly tips and tricks to optimize the application of a da Vinci® robot in simple or radical hysterectomies.

    This study explored the rather rapid adoption of a new surgical device - the da Vinci robot - in the Netherlands despite the high costs and its controversial clinical benefits. We used the concept 'affordances' as a conceptual-analytic tool to refer to the perceived promises, symbolic meanings, and utility values of an innovation constructed in the wider social context of use. This concept helps us empirically understand robot adoption. Data from 28 in-depth interviews with diverse purposively-sampled stakeholders, and from medical literature, policy documents, Health Technology Assessment reports, congress websites and patients' weblogs/forums between April 2009 and February 2014 were systematically analysed from the perspective of affordances. We distinguished five interrelated affordances of the robot that accounted for shaping and fulfilling its rapid adoption: 'characteristics-related' affordances such as smart nomenclature and novelty, symbolising high-tech clinical excellence; 'research-related' affordances offering medical-technical scientific excellence; 'entrepreneurship-related' affordances for performing better-than-the-competition; 'policy-related' affordances indicating the robot's liberalised provision and its reduced financial risks; and 'communication-related' affordances of the robot in shaping patients' choices and the public's expectations by resonating promising discourses while pushing uncertainties into the background. These affordances make the take-up and use of the da Vinci robot sound perfectly rational and inevitable. This Dutch case study demonstrates the fruitfulness of the affordances approach to empirically capturing the contextual dynamics of technology adoption in health care: exploring in-depth actors' interaction with the technology while considering the interpretative spaces created in situations of use. This approach can best elicit real-life value of innovations, values as defined through the eyes of (potential) users.

    Full Text Available Mit der Einführung des da VinciTM-Operationsroboters steht ein neues Werkzeug zur Verfügung, welches das Spektrum der minimalinvasiven Operationstechniken erweitert und totalendoskopische Operationen am Herzen ermöglicht. Seit Juni 1999 wurden an unserer Klinik 30 roboterunterstützte Eingriffe am Herzen durchgeführt. Das Spektrum der durchgeführten Operationen umfaßt totalendoskopische Bypassoperationen (TECAB mit links- oder rechtsseitigem A. mammaria-Bypass (LIMA oder RIMA zum R. interventricularis anterior (RIVA oder zur rechten Kranzarterie (RCA, aber auch Zweifachbypasseingriffe als sequentieller Mammariabypass zum RIVA und zum R. diagonalis. Sogar bilaterale A. mammaria-Versorgung des RIVA und der RCA ist mit computerunterstützter Telemanipulation erfolgreich realisiert worden. Des weiteren ist bei drei Patienten ein Atrium-Septum-Defekt in totalendoskopischer Technik sowohl mit Direktnaht als auch mit Patchverschluß korrigiert worden. Die durchschnittliche Operationszeit der 13 "closed chest"-Bypasspatienten betrug 354 ± 10 Minuten, die extrakorporale Zirkulationszeit 167 ± 11 Minuten und die Aortenklemmzeit 65 ± 7 Minuten. Außer drei Patienten hatten alle einen unkomplizierten postoperativen Verlauf und wurden in gutem Allgemeinzustand nach Hause entlassen. Bei zwei Patienten nach TECAB war eine Rethorakotomie wegen Blutung bzw. Perikardtamponade erforderlich. Eine Patientin wurde reanimationspflichtig als Folge einer vasoplegiebedingten Hypovolämie. Alle TECAB-Patienten wurden vor Entlassung aus dem Krankenhaus nachangiographiert und zeigten exzellente angiographische Ergebnisse. Wir haben gezeigt, daß computerunterstützte totalendoskopische Einfach- und Zweifachbypassoperationen sowie ASD-Verschlüsse mit dem da VinciTM-Telemanipulationssystem durchführbar sind. Obwohl eine gewisse Lernphase erforderlich ist, sind die initialen klinischen und funktionellen Ergebnisse gut. Die computerunterstützte endoskopische

    Video monitoring system (VMS) has been extensively applied in domains of target recognition, traffic management, remote sensing, auto navigation and national defence. However the VMS has a strong dependence on the weather, for instance, in foggy weather, the quality of images received by the VMS are distinct degraded and the effective range of VMS is also decreased. All in all, the VMS performs terribly in bad weather. Thus the research of fog degraded images enhancement has very high theoretical and practical application value. A design scheme of a fog degraded images enhancement system based on the TI DaVinci processor is presented in this paper. The main function of the referred system is to extract and digital cameras capture images and execute image enhancement processing to obtain a clear image. The processor used in this system is the dual core TI DaVinci DM6467T - ARM@500MHz+DSP@1GH. A MontaVista Linux operating system is running on the ARM subsystem which handles I/O and application processing. The DSP handles signal processing and the results are available to the ARM subsystem in shared memory.The system benefits from the DaVinci processor so that, with lower power cost and smaller volume, it provides the equivalent image processing capability of a X86 computer. The outcome shows that the system in this paper can process images at 25 frames per second on D1 resolution.

    Minimally invasive surgery carries the deadly risk of rupturing major blood vessels, such as the internal carotid arteries hidden by bone in endonasal transsphenoidal surgery. We propose a novel approach to surgical guidance that relies on photoacoustic-based vessel separation measurements to assess the extent of safety zones during these type of surgical procedures. This approach can be implemented with or without a robot or navigation system. To determine the accuracy of this approach, a custom phantom was designed and manufactured for modular placement of two 3.18-mm diameter vessel-mimicking targets separated by 10-20 mm. Photoacoustic images were acquired as the optical fiber was swept across the vessels in the absence and presence of teleoperation with a research da Vinci Surgical System. When the da Vinci was used, vessel positions were recorded based on the fiber position (calculated from the robot kinematics) that corresponded to an observed photoacoustic signal. In all cases, compounded photoacoustic data from a single sweep displayed the four vessel boundaries in one image. Amplitude- and coherence-based photoacoustic images were used to estimate vessel separations, resulting in 0.52-0.56 mm mean absolute errors, 0.66-0.71 mm root mean square errors, and 65-68% more accuracy compared to fiber position measurements obtained through the da Vinci robot kinematics. Results indicate that with further development, photoacoustic image-based measurements of anatomical landmarks could be a viable method for real-time path planning in multiple interventional photoacoustic applications.

    The standard low lithotomic position, used during robot-assisted radical prostatectomy (RARP), with prolonged positioning in stirrups together with steep Trendelenburg may expose the patient to neurapraxia phenomena of the lower limbs and can rarely be used in patients with problems of hip abduction. To overcome these hurdles, we evaluated the clinical benefits of "side docking" (SD) of the da Vinci(®) robotic system in comparison to "traditional docking" (TD). A cohort of 120 patients submitted to RARP were prospectively randomized into two groups by docking approach: SD with the patient supine with lower limbs slightly abducted on the operating table, and TD docking time, intraoperative number of collisions between the robotic arms and postoperative neurological problems in the lower limbs were noted. Descriptive statistics was used to analyze outcomes. Docking time was shorter for the SD group [SD: median 13 min (range 10-18); TD: median 21 min (range 15-34)]. None in the SD group and six of 60 patients (10%) in the TD group suffered from temporary (<30 days) unilateral neurological deficits of the lower limbs. In both groups no collisions between the robotic arms occurred. The SD approach is technically feasible. It does not cause collisions between the robotic arms, and is a reliable method for reducing the setup time of RARP. The supine position of the patient may prevent neurological complications of the lower limbs. Based on these results, SD has become the standard docking technique used by our department.

    The da Vinci ™Robotic System (dVRS) is the latest advancement in laparoscopic surgery allowing the surgeon more accurate and precise control of instrumentation with an added three-dimensional image. Technology comes with a price, $1.3 million. Due to charitable contributions from the Durham family, the University of Nebraska was the eighth Medical Center in the USA to obtain a dVRS in June 2000. UNMC analyzed 224 dVRS surgical procedures from July 2000 to February 2007. These procedures were designated by surgical service and further scrutinized for length of stay, and cost. We also reviewed trends in operative usage, academic and public relations components with this innovative technology. The dVRS was used for multiple other purposes that were beneficial including research with engineering graduate students, training for surgical residents, display and demos as a means for public relations. Primarily general and urologic surgeons utilized the dVRS. General surgeons were the early adopters of the new technology, the greatest growth and utilization of the equipment has been in urologic procedures, which has outpaced general surgery in the past year. Cost analysis shows a subtle benefit with a reduced length of stay by an average of 4 days. Average direct costs were found to be greater with the dVRS by $1,470. Overall, the effects of the dVRS are vast reaching and are fundamental to the growth of an academic institution and continued progress in minimally invasive surgery.

    PHENOMENON: Virtual reality simulators are the subject of several recent studies of skills training for robot-assisted surgery. Yet no consensus exists regarding what a core skill set comprises or how to measure skill performance. Defining a core skill set and relevant metrics would help surgical educators evaluate different simulators. This review draws from published research to propose a core technical skill set for using the da Vinci surgeon console. Publications on three commercial simulators were used to evaluate the simulators' content addressing these skills and associated metrics. An analysis of published research suggests that a core technical skill set for operating the surgeon console includes bimanual wristed manipulation, camera control, master clutching to manage hand position, use of third instrument arm, activating energy sources, appropriate depth perception, and awareness of forces applied by instruments. Validity studies of three commercial virtual reality simulators for robot-assisted surgery suggest that all three have comparable content and metrics. However, none have comprehensive content and metrics for all core skills. INSIGHTS: Virtual reality simulation remains a promising tool to support skill training for robot-assisted surgery, yet existing commercial simulator content is inadequate for performing and assessing a comprehensive basic skill set. The results of this evaluation help identify opportunities and challenges that exist for future developments in virtual reality simulation for robot-assisted surgery. Specifically, the inclusion of educational experts in the development cycle alongside clinical and technological experts is recommended.

    We report our initial experiences of robot-assisted cardiac surgery using the da Vinci Surgical System. Between February 2010 and March 2014, 50 consecutive patients underwent minimally invasive robot-assisted cardiac surgery. Robot-assisted cardiac surgery was employed in two cases of minimally invasive direct coronary artery bypass, 17 cases of mitral valve repair, 10 cases of cardiac myxoma removal, 20 cases of atrial septal defect repair, and one isolated CryoMaze procedure. Average cardiopulmonary bypass time and average aorta cross-clamping time were 194.8±48.6 minutes and 126.1±22.6 minutes in mitral valve repair operations and 132.0±32.0 minutes and 76.1±23.1 minutes in myxoma removal operations, respectively. During atrial septal defect closure operations, the average cardiopulmonary bypass time was 128.3±43.1 minutes. The median length of stay was between five and seven days. The only complication was that one patient needed reoperation to address bleeding. There were no hospital mortalities. Robot-assisted cardiac surgery is safe and effective for mitral valve repair, atrial septal defect closure, and cardiac myxoma removal surgery. Reducing operative time depends heavily on the experience of the entire robotic surgical team.

    The integrity of the medical literature about robotic surgery remains unclear despite wide-spread adoption. We sought to determine if payment from Intuitive Surgical Incorporated (ISI) affected quality of the research produced by surgeons. Publicly available financial data from the CMS website regarding the top-20 earners from ISI for 2015 was gathered. Studies conducted by these surgeons were identified using PubMed. Inclusion criteria consisted of publications about the da Vinci(®) robot on patient outcomes. The primary outcome of our study was if the study conclusion was positive/equivocal/negative towards the robot. Secondary outcomes included authorship, sponsorship, study controls, and disclosure. The top earners received $3,296,844 in 2015, with a median of $141,959. Sub-specialties included general surgery (55%), colorectal (20%), thoracic (15%), and obstetrics/gynecology (10%). Of the 37 studies, there was 1 RCT, with observational studies comprising the rest. The majority of the studies (n = 16, 43%) had no control population, with 11 (30%) comparing to same institution/surgeon, Though ISI sponsored only 6 (16%) studies, all with positive conclusions, 27 (73%) studies had positive conclusions for robot use, 9 (24%) equivocal, and only 1 (3%) negative. Overall, 13 earners had lead authorship and 11 senior. This initial pilot study highlights a potential bias as current literature published by benefactors demonstrates low quality and highly positive conclusions towards approval of the robot. This substantiates the need for a large, systematic review of the potential influence of sponsoring surgeons on medical literature. Copyright © 2017 Elsevier Inc. All rights reserved.

  19. Notes on the Leonardo Case

    Directory of Open Access Journals (Sweden)

    Alessandro Serra

    2010-12-01

    Full Text Available Conceived as the first part of an unpublished broader study, this brief essay by Alessandro Serra analyzes different reactions towards one of Freud’s most famous works: "Leonardo da Vinci and a Memory of His Childhood" (1910. From Ernst Kris to Meyer Schapiro, psychoanalysts, psychologists and art historians agreed to reject the general conclusions of Freud’s essay, yet saving its theoretic assumptions. In fact, Freud’s work would remain an important part of author’s opera only because it represents the first time in which the “pulsion theory” appeared and the concept of “sublimation” is completely developed. But for Serra this is not enough. The author quotes a long passage from Freud’s paper, highlighting the historical and critical influences that contributed to its realisation. He dwells upon the famous mistranslation, which transforms Leonardo’s ‘kite’ into Freud’s ‘vulture’, and reviews Jung’s and the Protestant minister Pfister’s positions (mentioning also that of Christensen, who in a paper published in the influential “Psychoanalytic Review” in 1944 even talks about Leonardo’s eagle. In this way, while emphasizing the sequence of errors in this specific case, Serra reaffirms the importance of the psychoanalytic contribution – and in particular the “psychobiographical” one – for a flexible comprehension of the act of making art, which in the words of Merleau-Ponty which conclude the essay, is understood as an interpretation of the “exchange between the future and the past”.

    Despite the increased dexterity and precision of robotic surgery, like any new surgical technology it is still associated with a learning curve that can impact patient outcomes. The use of surgical simulators outside of the operating room, in a low-stakes environment, has been shown to shorten such learning curves. We present a multidisciplinary validation study of a robotic surgery simulator, the da Vinci(®) Skills Simulator (dVSS). Trainees and attending faculty from the University of Toronto, Departments of Surgery and Obstetrics and Gynecology (ObGyn), were recruited to participate in this validation study. All participants completed seven different exercises on the dVSS (Camera Targeting 1, Peg Board 1, Peg Board 2, Ring Walk 2, Match Board 1, Thread the Rings, Suture Sponge 1) and, using the da Vinci S Robot (dVR), completed two standardized skill tasks (Ring Transfer, Needle Passing). Participants were categorized as novice robotic surgeon (NRS) and experienced robotic surgeon (ERS) based on the number of robotic cases performed. Statistical analysis was conducted using independent T test and non-parametric Spearman's correlation. A total of 53 participants were included in the study: 27 urology, 13 ObGyn, and 13 thoracic surgery (Table 1). Most participants (89 %) either had no prior console experience or had performed concurrent validity was also demonstrated as dVSS scores for most exercises correlated with performance of the two standardized skill tasks using the dVR (Table 3). This multidisciplinary validation study of the dVSS provides excellent face, content, construct, and concurrent validity evidence, which supports its integrated use in a comprehensive robotic surgery training program, both as an educational tool and potentially as an assessment device.

    Full Text Available Khalid H SaitObstetrics and Gynecology Department, Faculty of Medicine, Gynecology Oncology Unit, King Abdulaziz University Hospital, Jeddah, Saudi ArabiaBackground: The purpose of this study was to review our experience and the challenges of using the da Vinci® surgical system robot during gynecological surgery at King Abdulaziz University Hospital.Methods: A retrospective study was conducted to review all cases of robot-assisted gynecologic surgery performed at our institution between January 2008 and December 2010. The patients were reviewed for indications, complications, length of hospital stay, and conversion rate, as well as console and docking times.Results: Over the three-year period, we operated on 35 patients with benign or malignant conditions using the robot for a total of 62 surgical procedures. The docking times averaged seven minutes. The mean console times for simple hysterectomy, bilateral salpingo-oophorectomy, and bilateral pelvic lymphadenectomy were 125, 47, and 62 minutes, respectively. In four patients, laparoscopic procedures were converted to open procedures, giving a conversion rate of 6.5%. All of the conversions were among the first 15 procedures performed. The average hospital stay was 3 days. Complications occurred in five patients (14%, and none were directly related to the robotic system.Conclusion: Our early experience with the robot show that with proper training of the robotic team, technical difficulty with the robotic system is limited. There is definitely a learning curve that requires performance of gynecological surgical procedures using the robot.Keywords: da Vinci robot, gynecological surgery, laparoscopy

    In Japan, as of September 2007, prostatectomy is conducted with open surgical procedures in more than 90% of the cases. Following the first reported robotic prostatectomy by Binder, et al. in 2000, a robotic-assisted laparoscopic radical prostatectomy (RALP) using the daVinci Surgical System (Intuitive Surgical, Inc., Sunnyvale, California, USA) has been extensively used as a standard procedure with gratifying results in the United States. In the Asian region, in contrast, RALP is still in an introductory phase. Recently, we introduced RALP in Japan. A total of 24 patients received robotic surgery within a year since August 2006. RALP was completed in all patients without conversion to open surgery, except for the first patient in whom a restriction to a 2-hour operation had been imposed by the Ethical Committee. The mean operative time using the daVinci device and the mean estimated blood loss were 232.0 (range; 136-405) minutes and 313.0 (range; 10-1,000) ml, respectively. The training program we recently developed proved remarkably effective in reducing the learning curve of robotic surgery in Japan, where there is no person with expertise in this operating procedure. In particular, the intraoperative guidance given by the expert was useful after relevant problematic points were delineated by operators who received comprehensive video-based image training and actually performed robot surgery in several cases. With direct intraoperative guidance by the mentor during cases 13 and 14, both the operation time and estimated blood loss was markedly reduced.

    This article studies a fragment on the conic sections that appear in the Codex Atlanticus, fols. 611rb/915ra. Arguments are put forward to assemble these two folios. Their comparison with the Latin texts available before 1500 shows that they derive from the De speculis comburentibus of Alhacen and the De speculis comburentibus of Regiomontanus, joined together in his autograph manuscript (Vienna, Oster. Nationalbibliothek, Cod. 5258). Having identified the sources, and discussed their mathematics, the issue of their transmission is targeted. It is shown that these notes were written by Paolo dal Pozzo Toscanelli, through whom they reached the notebooks of Leonardo da Vinci.

    The technique used by Leonardo da Vinci to paint flesh tints--the sfumato--has never been scientifically depicted until now. From 100,000,000 reflectance spectra recorded on Mona Lisa, a virtual removal of the varnish is first obtained. A unique umber pigment is then identified in the upper layer and an exceptional maximum of the color saturation is underlined, both characteristics of a glaze technique. The modeling calling upon the radiative transfer equation confirms this maximum of saturation, the identification of an umber in the upper layer, and moreover underlines a mixture of 1% vermilion and 99% lead white in the base layer. Finally, the modeling, using the auxiliary function method, explains the spectacular maximum of saturation by the multiple scattering.

    The key to successful rectal cancer resection is to perform complete total mesorectal excision (TME). Laparoscopic TME can be challenging, especially in the narrow confines of the pelvis. Robotic-assisted surgery can overcome these limitations through superior three-dimensional (3-D) visualization and the increased range of movements provided by the endowrist function. To date, all totally robotic resections of the rectum have been described using da Vinci® S or Si systems. Due to the limitations of the standard system, only hybrid procedures have been described so far. To evaluate the feasibility and short-term outcomes of performing totally robotic-assisted laparoscopic colorectal resections using the standard da Vinci® system with a fourth arm extension. The standard system was docked from the patient's left hip. Four 8-mm robotic trocars were inserted. Upon completion of phase 1 (pedicle ligation, colonic mobilization, splenic flexure takedown), the two left-sided arms are repositioned to allow phase 2 (pelvic dissection), enabling the entire procedure except for the distal transection and anastomosis to be performed robotically. Twenty-one robotic procedures were performed from August 2008 to September 2009. The mean age of the patients was 61 years (13 males). The procedures performed included seven anterior resections, seven low anterior resections, five ultralow anterior resections, one abdominoperineal resection, and one resection rectopexy. The majority of the cases were performed in patients with colon or rectal cancer. Operative time ranged from 232 to 444 (mean 316) min. Postoperative morbidity occurred in three patients (14.3%) with no mortalities or conversions. Average hospital stay was 6.4 days. Mean lymph node yield for the cases with cancer was 17.8. The standard da Vinci® system with four arms can be used to perform totally robotic-assisted colorectal procedures for the left colon and rectum with short-term outcomes similar to those of

    Prodigious efforts and landmark discoveries have led toward significant advances in our understanding of atherosclerosis. Despite significant efforts, atherosclerosis continues globally to be a leading cause of mortality and reduced quality of life. With surges in the prevalence of obesity and diabetes, atherosclerosis is expected to have an even more pronounced impact upon the global burden of disease. It is imperative to develop strategies for the early detection of disease. Positron emission tomography (PET) imaging utilizing [(18)F]fluorodeoxyglucose (FDG) may provide a non-invasive means of characterizing inflammatory activity within atherosclerotic plaque, thus serving as a surrogate biomarker for detecting vulnerable plaque. The aim of this review is to explore the rationale for performing FDG imaging, provide an overview into the mechanism of action, and summarize findings from the early application of FDG PET imaging in the clinical setting to evaluate vascular disease. Alternative imaging biomarkers and approaches are briefly discussed.

    Herein, we describe several steps to improve surgeon autonomy during a Left Robotic-Assisted Laparoscopic Radical Nephrectomy (RALRN), using the Da Vinci Si system. Our kidney cancer program is based on 2 community hospitals. We use the Da Vinci Si system. Access is obtained with the following trocars: Two 8 mm robotic, one 8 mm robotic, bariatric length (arm 3), 15 mm for the assistant and 12 mm for the camera. We use curved monopolar scissors in robotic arm 1, Bipolar Maryland in arm 2, Prograsp Forceps in arm 3, and we alternate throughout the surgery with EndoWrist clip appliers and the vessel sealer. Here, we described three steps and the use of 3 robotic instruments to improve surgeon autonomy. Step 1: the lower pole of the kidney was dissected and this was retracted upwards and laterally. This maneuver was performed using the 3rd robotic arm with the Prograsp Forceps. Step 2: the monopolar scissors was replaced (robotic arm 1) with the robotic EndoWrist clip applier, 10 mm Hem-o-Lok. The renal artery and vein were controlled and transected by the main surgeon. Step 3: the superior, posterolateral dissection and all bleeders were carefully coagulated by the surgeon with the EndoWrist one vessel sealer. We have now performed 15 RALRN following these steps. Our results were: blood loss 300 cc, console time 140 min, operating room time 200 min, anesthesia time 180 min, hospital stay 2.5 days, 1 incisional hernia, pathology: (13) RCC clear cell, (1) chromophobe and (1) papillary type 1. Tumor Stage: (5) T1b, (8) T2a, (2) T2b. We provide a concise, step-by-step technique for radical nephrectomy (RN) using the Da Vinci Si robotic system that may provide more autonomy to the surgeon, while maintaining surgical outcome equivalent to standard laparoscopic RN.

    Sentinel lymph node (SLN) mapping has emerged as the new frontier for the surgical staging of apparently early-stage cervical and endometrial cancer. Different colorimetric and radioactive tracers, alone and in combination, have been proposed with encouraging results. Fluorometric mapping using indocyanine green (ICG) appears to be a suitable and attractive alternative to provide reliable staging [1-4]. In this video, we present the technique of SLN mapping in 2 cases (1 endometrial and 1 cervical cancer, respectively) using ICG and the near-infrared technology provided by the newest Da Vinci Xi robotic system (Intuitive Surgical Inc., Sunnyvale, CA). Together we report the results of our preliminary experience on the first 20 cases performed. The new robotic Da Vinci Xi system was available at our institution since May 2015. Upon institutional review board/ethical committee approval, all consecutive patients with early-stage endometrial and cervical cancer who were judged suitable for robotic surgery have been enrolled for SLN mapping with ICG. We adopted the Memorial Sloan Kettering Cancer Center SLN algorithm; the tracer was delivered into the cervix in all cases. Four milliliters (1.25 mg/mL) of ICG was injected divided into the 3- and 9-o'clock positions of the cervix alone, with 1 mL deep into the stroma and 1 mL submucosally at the skin incision. Sentinel lymph nodes were examined with a protocol including both ultrastaging with immunohistochemistry [3] and 1-step nucleic acid amplification assay [5,6] under a parallel protocol of study. During the study period, 20 cases were managed; 14 and 6 patients had endometrial and cervical cancer, respectively. SLN was detected in all cases (20/20, 100%). Bilateral SLNs were detected in 17 of 20 (85.0%) cases. Based on preoperative and intraoperative findings, 13 (65.0%) patients received systematic pelvic lymphadenectomy after SLN mapping. Three (15.0%) patients had microscopic nodal metastases on SLN. No

  10. Why the fuss over Brown’s The Da Vinci code? The dynamism of 'icons' and the in/stability of meaning

    2009-07-01

    Full Text Available Dan Brown’s book, “The Da Vinci code” (2003 and the sub-sequent motion picture by the same title (2006, have created a considerable stir within, but not limited to, Christian circles. The cause of the controversy is that, despite Brown’s overt pre-sentation of this work as fiction, it draws on figures, events and themes regarded in religious circles as sacred – most par-ticularly in Christian circles. Holy figures, events and themes are sensitive matters to believers: the meanings attached to them are regarded as essentially fixed, with connotations of perma-nence and eternity. Literature of many kinds, however, reinter-pret set meanings, loosening their perceived inflexibility, thus opening up a dynamism quite foreign to popular notions of definite meaning.

  11. Elastography using multi-stream GPU: an application to online tracked ultrasound elastography, in-vivo and the da Vinci Surgical System.

    Directory of Open Access Journals (Sweden)

    Nishikant P Deshmukh

    Full Text Available A system for real-time ultrasound (US elastography will advance interventions for the diagnosis and treatment of cancer by advancing methods such as thermal monitoring of tissue ablation. A multi-stream graphics processing unit (GPU based accelerated normalized cross-correlation (NCC elastography, with a maximum frame rate of 78 frames per second, is presented in this paper. A study of NCC window size is undertaken to determine the effect on frame rate and the quality of output elastography images. This paper also presents a novel system for Online Tracked Ultrasound Elastography (O-TRuE, which extends prior work on an offline method. By tracking the US probe with an electromagnetic (EM tracker, the system selects in-plane radio frequency (RF data frames for generating high quality elastograms. A novel method for evaluating the quality of an elastography output stream is presented, suggesting that O-TRuE generates more stable elastograms than generated by untracked, free-hand palpation. Since EM tracking cannot be used in all systems, an integration of real-time elastography and the da Vinci Surgical System is presented and evaluated for elastography stream quality based on our metric. The da Vinci surgical robot is outfitted with a laparoscopic US probe, and palpation motions are autonomously generated by customized software. It is found that a stable output stream can be achieved, which is affected by both the frequency and amplitude of palpation. The GPU framework is validated using data from in-vivo pig liver ablation; the generated elastography images identify the ablated region, outlined more clearly than in the corresponding B-mode US images.

    There has been little enthusiasm for performing robotic colectomy for colon cancer in recent years due to multiple factors, one being that the previous robotic systems such as the da Vinci Si(®) (dVSi) were poorly designed for multi-quadrant surgery. The new da Vinci Xi(®) (dVXi) system enables colectomy with central mesocolic excision to be performed easily in a single docking procedure. We developed a universal port placement strategy to allow right and left hemicolectomies to be performed via a suprapubic approach and a Pfannensteil extraction site. This proof of concept paper describes the development and subsequent clinical application of this setup. After extensive training on the dVXi system concepts in collaboration with clinical development engineers, we developed a port placement strategy which was tested and adapted after performing experimental surgery in three cadaveric models. Subsequently our port placement was used for two clinical cases of suprapubic right and left hemicolectomy. With some modifications of port placements after the initial cadaveric colectomies, we have developed a potentially universal suprapubic port placement strategy for robotic colectomy with complete mesocolic excision and central vascular ligation using the dVXi robotic system. This port placement strategy was applied successfully in our first two clinical cases. Based on our cadaveric laboratory as well as our initial clinical application, the suprapubic port placement strategy for the dVXi system with its improved features over the dVSi can feasibly perform right and left hemicolectomy with complete mesocolic excision and central vascular ligation. Further studies will be required to establish efficacy as well as safety profile of these procedures.

    The first few cases of colonic surgery using Da Vinci surgical system were reported in 2002;since then,Da Vinci surgical system has gradually been used in several centers for rectal cancer and with favorable outcomes.Laparoscopy has opened a new era in modern surgery,however,the inherent limitations of traditional laparoscopic surgery may cause certain difficulties during manipulation,especially in the demanding field of colonic laparoscopic surgery,which prolonged the learning curve.The advantages of Da Vinci surgical system include stable camera platform,three-dimensional imaging,excellent ergonomics,tremor elimination,ambidextrous capability,motion scaling,and instruments with multiple degrees of freedom.Low rectal region was regarded as the"forbidden zone"for laparoscopy,so we applied the Da Vinci surgical system in low anterior resection for rectal cancer.Because of mulyiquadrant operations in low anterior resection of rectal cancer,moving the robotic cart twice during the operation is necessary,which increased the operation time.In order to solve the problem,many surgeons use conventional laparoscopy for vessel ligation and flexure mobilization,and adopt the Da Vinci surgical system only in the lower quadrant of the abdomen.We present a technique that allows for the complete isolation of the mesorectum from the same position of the robotic cart,during the process,the enhanced dexterity and precise dissection offered by the Da Vinci surgical system were fully utilized.%@@ 1994年经美国FDA批准,自动定位内镜系统作为机器人持镜手应用于普通外科临床,此后又开发了宙斯机器人系统,但FDA仅批准其作为外科手术助手而不能作为真正的手术者.达芬奇机器人手术系统是FDA批准的第1台真正应用于腹部外科的手术系统.自2001年开始,达芬奇机器人手术系统被应用于结直肠外科的微创治疗.我科于2009年6月成功完成了国内第1例低位直肠癌前切除术,效果良好.

    Full Text Available Objective: To determine the attitudinal change for urologic surgery in Greece since the introduction of the da Vinci Surgical System (DVS. We describe contemporary trends at public hospital level, the initial Greek experience, while at the same time Greece is in economic crisis and funding is under austerity measures. Materials and Methods: We retrospectively analyzed annualized case log data on urologic procedures, between 2008 (installation of the DVS and 2013, from “Laiko’’ Hospital in Athens. We evaluated, using summary statistics, trends and institutional status regarding robot-assisted surgery (RAS. We also analyzed the relationship between the introduction of RAS and change in total volume of procedures performed. Results: 1578 of the urological procedures performed at “Laiko’’ Hospital were pooled, 1342 (85% being open and 236 RAS (15%. We observed a 6-fold increase in the number of RAS performed, from 7% of the total procedural volume (14/212 in 2008 to 30% (96/331 in 2013. For radical prostatectomy, in 2008 2% were robot-assisted and 98% open while in 2013, 46% and 54% respectively. Pyeloplasty was performed more often using the robot-assisted method since 2010. RAS-dedicated surgeons increased both RAS and the total number of procedures they performed. From 86 in 2008 to 145 in 2013, with 57% of them being RAS in 2013 as compared to 13 % in 2008. Conclusions: Robot-assisted surgery has integrated into the armamentarium for urologic surgery in Greece at public hospital level. Surgical robot acquisition is also associated with increased volume of procedures, especially prostatectomy, despite the ongoing debate over cost-effectiveness, during economic crisis and International Monetary Fund (IFN era.

    There is a growing interest in achieving higher survival rates with the lowest morbidity in localized prostate cancer (PC) treatment. Consequently, minimally invasive techniques such as low-dose rate brachytherapy (BT) and robotic-assisted prostatectomy (RALP) have been developed and improved. Comparative analysis of functional outcomes and quality of life in a prospective series of 51BT and 42Da Vinci prostatectomies DV Materials and Methods: Comparative analysis of functional outcomes and quality of life in a prospective series of 93 patients with low-risk localized PC diagnosed in 2011. 51patients underwent low-dose rate BT and the other 42 patients RALP. IIEF to assess erectile function, ICIQ to evaluate continence and SF36 test to quality of life wee employed. ICIQ at the first revision shows significant differences which favour the BT group, 79% present with continence or mild incontinence, whereas in the DV group 45% show these positive results. Differences disappear after 6 months, with 45 patients (89%) presenting with continence or mild incontinence in the BT group vs. 30 (71%) in the DV group. 65% of patients are potent in the first revision following BT and 39% following DV. Such differences are not significant and cannot be observed after 6 months. No significant differences were found in the comparative analysis of quality of life. ICIQ after surgery shows significant differences in favour of BT, which disappear after 6 months. Both procedures have a serious impact on erectile function, being even greater in the DV group. Differences between groups disappear after 6 months. Copyright® by the International Brazilian Journal of Urology.

    2015-12-01

    Full Text Available The central theme of the book, as argued in Thomas Frangenberg’s Introduction, is that the legacy of Vasari’s Lives is complex and ambivalent because, on the one hand, it is composed of fictional anecdotes; but on the other hand, it is based on a highly reliable source almost contemporary with Leonardo’s lifetime. This review considers that the main interpretive challenge of the genre of biography has always been where and how to define the terrain in which fact and fiction co-exist. One of the strengths of The Lives of Leonardo is that it includes study of the factually verifiable, the philologically trackable, the mythical, and the psychological biography within the covers of the same book. This review locates the twelve case studies spanning 400 years of Leonardo biographies within the history of scholarship on artist’s biographies. It considers questions of authorship, intertextuality, cultural capital, and poetics and provides summaries of the individual chapters.

  2. [The "myologie dynamique" by Girolamo Fabrizi da Aquapendente in the scientific language in the Renaissance age (XVI-XVII)].

    Science.gov (United States)

    Stroppiana, L

    1989-01-01

    Beginning from the XV century, mechanical materialism underwent an evolution in "biological mechanics" within the scientific doctrine. Among the greatest exponents of this new current there were two Italian men, Leonardo da Vinci (1452-1519) and Girolamo da Acquapendente (1533-1619). By the trend given by Leonardo, the myology, instead of being a static science, took a dynamic meaning and valence. Later, Fabrizi resumed and investigated the subject above all in its less known expression, elaborating an original theory. With Acquapendente, the anatomy lost its merely descriptive pecularity and evolved in analysis of the structure in connection with the function. Moreover, he opposed the syllogism against the mechanic language and the mathematical formulation. A new scientific way will be afterwards characterized by Galileo Galilei in the field of the physics and by Giovanni Alfonso Borrelli in the biology.

    Between 1505 and 1506 Leonardo Da Vinci painted his masterpiece, the Battle of Anghiari, in Palazzo Vecchio's Hall of 500 in Florence. The unfinished mural remained visible until 1563, when architect Giorgio Vasari undertook a renovation of the Hall and all traces of the Battle of Anghiari were lost. However, scholarly interpretation and scientific evidence suggest that the mural could be on the eastern wall, hidden behind a brick wall built in 1563 by Vasari. This paper discusses the possibility of using NNA/APT (Nanosecond Neutron Analysis/Associated Particle Technique) to establish the presence of the masterpiece by identifying behind the Vasari's wall chemical elements from the gesso preparation layer of the mural and possibly from its pigments. This paper reports on the experiments run with a simple NNA/APT system and the Monte Carlo simulations that have been carried out in order to outline the experimental setup of an advanced NNA/APT able to detect and locate the tiny amount of gesso and pigments.

    Full Text Available A lenda de Édipo é a primeira aventura "policial" de nossa história e uma das mais modernas: um homem busca um assassino sem saber que é, ele próprio, este assassino. Freud ignora Sherlock Holmes, mas é para este que a reflexão ideal exige luz baixa e se recostar em um divã. Alguns contos de Edgar Allan Poe se tornaram passagens obrigatórias do pensamento psicanalítico francês, não sem problemas. Desde os primeiros estudos de Freud sobre Leonardo Da Vinci, a psicanálise aplicada sempre encontrou dificuldades, que talvez não sejam estranhas à técnica psicanalítica individual. Este artigo as examina.The myth of Oedipus is the first "mystery" adventure of our time and one of the most modern: a man searches for a murderer without knowing that he himself is the criminal. Freud ignores Sherlock Holmes, but this is the one that an ideal reflection requires a dim light and a couch. Some stories by Edgar Allan Poe have become required passages in French psychoanalytic thought, not without some trouble. Since Freud's first studies on Leonardo Da Vinci, applied psychoanalysis has always encountered difficulties that may not be so different from the ones faced by individual psychoanalytic technique. This article examines them.

    Laparoscopy was ifrst applied in 1990 and Da Vinci robotics surgical system emerged in 2002 in the ifeld of gastrointestinal surgery. Taking a wide view of the development of minimally invasive techniques in more than 20 years, surgeons have been grown up from the blindest pursuit of technological reform to standard application and objective evaluation, and constantly advanced to the update of technology, the consummate standards and the improvement of the efifcacy. Although laparoscopy and Da Vinci robotics surgical system possess the advantages of minimal invasiveness, less bleeding and rapid recovery, it is dififcult to be applied and spread. However, the three-dimensional laparoscopy has brought a brand new revolution. It has not only the technical characteristics of laparoscopy and robotic surgical system, but also obvious advantage in popularity and learning. Thus, we believe that the prospect of three-dimensional laparoscopy will be broader.%1990年,腹腔镜技术首次应用于胃肠外科;2002年,达芬奇机器人手术系统开始在胃肠外科领域崭露头角。纵观微创技术发展的20多年历程,外科医师已从盲目追求技术改革逐渐发展至规范应用和客观评价,并不断向技术更新、标准完善和疗效肯定的高标准迈进。此外,外科医师在看到腹腔镜和达芬奇机器人手术系统创伤小、术中出血少、术后恢复快等优势的同时,也在不断思考它们在应用和推广方面难以避免的劣势。3D腹腔镜的问世为微创外科带来了新的革命,其不仅同时具有腹腔镜和机器人手术系统的技术特点,而且在推广和学习曲线方面也占据明显优势。因此,我们相信3D腹腔镜技术的应用前景将更为广阔。

    Posture, vision, and instrumentation limitations are the main predicaments of conventional laparoscopy. To combine the ETHOS surgical chair, the three-dimensional laparoscope, and the Radius Surgical System manipulators, and compare the system with conventional laparoscopy and da Vinci in terms of task completion times and discomfort. Fifteen trainees performed the three main laparoscopic suturing tasks of the Heilbronn training program (IV: simulation of dorsal venous complex suturing; V: circular suturing of tubular structure; and VI: urethrovesical anastomosis) in a pelvi trainer. The tasks were performed conventionally, utilizing the three devices, and robotically. Task completion times were recorded and the surgeon discomfort was evaluated using questionnaires. Task completion times were compared using nonparametric Wilcoxon signed rank test and ergonomic scores were compared using Pearson chi-square test. The use of the full laparoscopic set (ETHOS chair, three-dimensional laparoscopic camera, Radius Surgical System needle holders), resulted in a significant improvement of the completion time of the three tested tasks compared with conventional laparoscopy (psystem nullified heavy discomfort for Tasks IV and V and minimized it (6.7%) for the most demanding Task VI. Especially for Task VI, all trainees gained benefit, by using the system, in terms of task completion times and discomfort. The limited trainee robotic experience and the questionnaire subjectivity could be a potential limitation. The ergonomic laparoscopic system offers significantly improved task completion times and ergonomy than conventional laparoscopy. Furthermore, it demonstrates comparable results to robotic surgery. The study was conducted in a pelvi trainer and no patients were recruited. Copyright © 2016 European Association of Urology. Published by Elsevier B.V. All rights reserved.

    In making defect-free macromolecules, the challenge occurs during chemical synthesis. This challenge is especially pronounced in dendrimer synthesis where exponential growth quickly leads to steric congestion. To overcome this difficulty, proportionate branching in dendrimer growth is proposed. In proportionate branching, both the number and the length of branches increase exponentially but in opposite directions to mimic tree growth. The effectiveness of this strategy is demonstrated through the synthesis of a fluorocarbon dendron containing 243 chemically identical fluorine atoms with a MW of 9082 Da. Monodispersity is confirmed by nuclear magnetic resonance spectroscopy, mass spectrometry, and small-angle X-ray scattering. Moreover, growing different parts proportionately, as nature does, could be a general strategy to achieve defect-free synthesis of macromolecules.

    Full Text Available Ousando se aproximar de outras áreas do conhecimento, a psicanálise foi também marcada, como atestam inúmeros ensaios psicanalíticos, pelo alto apreço de Freud e Lacan em relação à arte. Um deles, percorrendo as adjacências entre o discurso freudiano, a teoria lacaniana e o mundo artístico, é considerado neste artigo: O Espaço Imanente (Rio de Janeiro: Imago, 1989. Este livro se aventura pelas longas divagações estético-freudianas, revendo as análises sobre o Moisés de Michelangelo, Leonardo da Vinci e a Gradiva de W.Jensen e os comentários de Lacan sobre o quadro de Hans Holbein, Os Embaixadores. Delas, rediscute a concepção de uma psicanálise da arte em torno da cisão entre o concreto, visível ou “externo” (o que existe concretamente na escultura de Michelangelo, na pintura de Da Vinci, no delírio do protagonista de Jensen, no quadro de Holbein, e o mental ou “interno” (o que torna a realidade pensada ou representada. Na contramarcha desta posição, assinala como o externo torna-se, também, condição para que o artista possa criar “internamente”. Insólito na leitura psicanalítica que sustenta, este ensaio agrega ao ar de liberdade que insufla a criação do artista diante de sua obra, traduzindo um aparente rompimento ou descompromisso dos conteúdos artísticos com qualquer ocorrência concreta, a organização física ou imanente dos objetos que se encontram na realidade.

    Full Text Available Partant de l’hypothèse qu’au cinéma, un plan travaillé à la manière d’un tableau engage, non pas un « arrêt » du récit, mais un enrichissement de la logique narrative linéaire du film par une sémiotique tabulaire et des jeux de références intermédiales, cet article analyse le cas exemplaire et récurrent des plans qui reconstituent en « tableau vivant » La Cène de Léonard de Vinci. Christus (Giulio Antamoro, 1914-1916, Ben Hur, a tale of the Christ (Fred Niblo, 1925 ou Quo Vadis (Mervyn LeRoy, 1951 y sont explorés, ainsi que d’autres productions qui replacent la composition du Cenacolo à la fois en une « phase » et une « stase » dramatique et esthétique du récit christique. Des films tels que Viridiana (Luis Buñuel, 1961 sont aussi évoqués, qui font apparaître la composition comme une pause allégorique d’un récit contemporain, enrichi sur un plan énonciatif, symbolique et iconographique.Based on the hypothesis that in the cinema, a shot worked in the style of a picture doesn’t “stop” the storyline but expands the linear narrative with tabular semiotics and artistic references, this article analyzes the exemplary and recurring case of the shots which reconstitute Leonardo da Vinci’s Last Supper as a “living picture”. Christus (Giulio Antamoro, 1914-1916, Ben Hur, a tale of the Christ (Fred Niblo, 1925, Quo Vadis (Mervyn LeRoy, 1951 and other movies are investigated, that replace the famous Cenacolo as both a phase and a stasis of the Christlike narrative. Films like Viridiana (Luis Buñuel, 1961 are mentioned too, where da Vinci’s composition occurs like an allegorical extension of a contemporary story, enriched both symbolically and iconographically.

    The daVinci Surgery System is an emerging technology,which has broaden the application of laparoscopy in surgical field.Since FDA approved the daVinci Surgical System in 2000,a number of medical institutions have used it in clinics worldwide and its clinical efficacy and safety have also been approved.Our department has completed 180 robot-assisted operations since the system was introduced into our hospital in 2011.Of these operations,4 were combined resection of organs(2.2%) in which one case was the rectal anterior resection and right hemicolectomy,one was the rectal anterior resection plus splenectomy,one was the rectal anterior re-section and appendectomy and one was the rectal anterior resection and hysterectomy.The most operations of combined resection of or-gans by using traditional laparoscopy were benign tumors.This is because that the radical resection of malignant tumor was relatively dif-ficult and the traditional laparoscopy has limitation to complete such operations.In contrast,the daVinci Surgical System has advantages of 7 degree-of-freedom operation instrument that makes the operation has a great dexterity.Therefore,the system has a great advantage in the operations of combined resection of organs.The operations in the 4 cases were successfully completed.Postoperative recovery was well and no serious complications were found.The authors suggested that the selection of the operation indications still need to be cau-tious and multidisciplinary cooperation and preoperative plan should be noticed.%机器人外科是一项新兴技术,拓宽了腹腔镜技术在外科领域的应用。达芬奇机器人手术系统自2000年获得FDA批准后,国外多家医疗机构陆续开展临床应用,其安全性与疗效已得到肯定与共识。沈阳军区总医院自2011年引进该设备,普外科目前共完成达芬奇机器人手术180例,其中腹腔多器官联合切除4例,占2.2%。4例中直肠前切除+右半结肠切除1例,

  15. Beam stripping extraction from the VINCY cyclotron

    Directory of Open Access Journals (Sweden)

    Ristić-Đurović Jasna L.

    2006-01-01

    Full Text Available The extraction system of a cyclotron guides an ion beam from a spiral acceleration orbit, through an extraction trajectory, into a high energy transport line. The two methods commonly used to direct an ion into the extraction path are deflection, by the electric field of an electrostatic deflector, and ion stripping, by a thin carbon foil. Compared to the electrostatic deflector system, the stripping extraction provides a fast and easy change of the extracted ion energy and is easier to manufacture operate, and maintain. However, the extraction trajectory and dynamics of an ion beam after stripping are highly dependant on the ion energy and specific charge. Thus, when a multipurpose machine such as the VINCY Cyclotron is concerned, it is far from easy to deliver a variety of ion beams into the same high energy transport line and at the same time preserve a reasonable compactness of the extraction system. The front side stripping extraction system of the VINCY Cyclotron provides high (~70 MeV and mid (~30 MeV energy protons, as well as a number of heavy ions in broad energy ranges. The back side stripping extraction system extracts low energy protons (~18 MeV and enables their simultaneous use with high energy protons at the front side of the machine.

This program simulates the response, i. e. calculates the magnetic field, of a previously defined model of a magnet. The accuracy of 3D field calculation depends on the density of the grid points in the simulation model grid. The size of the VINCY Cyclotron and the maximum number of grid points in the XY plane limited by MERMAID define the maximumobtainable accuracy of field calculations. Comparisons of the field simulated with maximum obtainable accuracy with the magnetic field measured in the first phase of the VINCY Cyclotron magnetic field measurements campaign has shown that the difference between these two fields is not as small as required. Further decrease of the difference between these fields is obtained by the simulation model calibration, i. e. by adjusting the current through the main coils in the simulation model.

This program simulates the response, i. e. calculates the magnetic field, of a previously defined model of a magnet. The accuracy of 3D field calculation depends on the density of the grid points in the simulation model grid. The size of the VINCY Cyclotron and the maximum number of grid points in the XY plane limited by MERMAID define the maximum obtainable accuracy of field calculations.

    Conclusion: Minimally invasive surgery is the trend of the future. Robot-assisted laparoscopic surgery is a new technique for myomectomy. This robotic system provides a three-dimensional operative field and an easy-to-use control panel, which may be of great help when applying the suturing techniques and may shorten the learning curve. More experience with and long-term follow-up of robotic surgery may be warranted to further validate the role the robot-assisted approach in gynecologic surgery.

    2012-01-01

    Objective: To summarize the epidural anesthesia combined with remifentanil and propofol intravenous injection, in the Da Vinci surgical robot assisted radical resection of esophageal cancer. Methods : Fifteen patients underwent selective robotic radical resection of esophageal cancer. All the patients were generally anesthetized using epidural anesthesia combined with remifentanil and propofol intravenous injection. The patients were intubated with double lumen endobronchial tube after anesthesia induction following epidural puncture, and underwent one-lung ventilation during intrathoracic operation. The blood gas, respiratory and hemodynamics parameters were monitored throughout the whole procedure. Results : All the 15 patients passed through the robotic surgery, and there was no conversion of thoracotomy occurred. The mean PaO2 and PaCO2 after anesthesia induction were (202.4±55.3) mmHg and (37.8±4.1) mmHg, and the mean PaO2 and PaCO2 30 minutes after one lung ventilation were (113.2±33.3) mmHg and (44.4±3.1) mmHg respectively. The anesthesia, operative and carbon dioxide pneumothorax duration were (245.4±40.7) min, (228.3±41.1) min and (210.3±33.1) min respectively. All the patients had (28.1±7.7) mmHg of blood pressure drop when the thorax was inflated with carbon dioxide, which was rectified by fast colloid injection and vasoactive agents. The patient-controlled epidural analgesia was applied and the patients were then transferred to PACU with single lumen intubation. Conclusion: Except that fast-track anesthesia can maintain adequately deep anesthesia and stable hemodynamics, and thus lessen surgical related stress and palliate postoperative pain, fast-track anesthesia can accelerate postoperative consciousness and muscular tension recovery, which may facilitate early extubation. As an important component of fast tract surgery, fast-track anesthesia is safe and reliable during the procedure the robotic surgery.%目的:总结硬膜外阻滞复合全

    First Instruments for the VLT Interferometer Summary A few months from now, light from celestial objects will be directed for the first time towards ESO's Very Large Telescope Interferometer (VLTI) at the Paranal Observatory (Chile). During this "First Light" event and the subsequent test phase, the light will be recorded with a special test instrument, VINCI (VLT INterferometer Commissioning Instrument). The main components of this high-tech instrument are aptly named MONA (a system that combines the light beams from several telescopes by means of optical fibers) and LISA (the infrared camera). VINCI was designed and constructed within a fruitful collaboration between ESO and several research institutes and industrial companies in France and Germany . It is now being assembled at the ESO Headquarters in Garching (Germany) and will soon be ready for installation at the telescope on Paranal. With the VLTI and VINCI, Europe's astronomers are now entering the first, crucial phase of an exciting scientific and technology venture that will ultimately put the world's most powerful optical/IR interferometric facility in their hands .

    Full Text Available Das rasche Wachstum des Bereichs Roboterchirurgie hat sich auch auf die akademischen Lehrprogramme ausgewirkt. Die herkömmliche Struktur der chirurgischen Ausbildungs- und Lehrtätigkeiten ist für die Vermittlung der Roboterchirurgie nicht besonders gut geeignet. Materialien und Methoden: Erfahrene Laparoskopie-Chirurgen können sich in speziellen Schulungskursen die Feinheiten der Roboterchirurgie relativ leicht aneignen. Dies gilt nicht für relativ unerfahrene chirurgische Praktikanten, wenngleich den Ausbildungsprogrammen auf jeden Fall die Verantwortung zukommt, auch das Fachgebiet der Robotertechnik zu lehren. Die Richtlinien des Amerikanischen Urologenverbands und des Accreditation Council on Graduate Medical Education werden geprüft und bei den Versuchen zur Bewältigung dieser Probleme herangezogen. Die einzelnen Verfahrensschritte, insbesondere die Prostatektomie, werden aus der Lehrendenperspektive betrachtet. Ergebnisse: Ein Curriculum der Roboterchirurgie kann in das Gesamtausbildungsprogramm erfolgreich integriert werden. Die Konsolenzeit wird auf die Erfahrung als Assistent am Krankenbett abgestimmt, ebenso wie die Entwicklung grundlegender laparoskopischer Fertigkeiten und eines Verständnisses der optischen Anatomie. Die Kompetenz als Klinikassistent ist erforderlich, bevor weitere Fortschritte zu den höheren Stufen der Konsolenbedienung erwogen werden können. Die chirurgischen Schritte werden in logische Fortschritte mit Fertigkeitseinheiten in verschiedenen Segmenten unterteilt, ehe eine Reihe von Segmenten zusammengesetzt werden kann, um signifikante Abschnitte der eigentlichen Operation zu ergeben. Schlußfolgerung: Das Lehren der Roboterchirurgie bringt neue und bislang unbekannte Schwierigkeiten mit sich. Diese neue Art der Chirurgie erfordert neue, innovative Lehrmethoden mit den obersten Zielen Sicherheit und Wirksamkeit. Es wird leichter werden, wenn auf dem Gebiet der Roboterchirurgie insgesamt mehr Erfahrungswerte vorliegen.

    This report describes a pair of brief, interactive classroom exercises utilizing Renaissance artists’ depictions of the brain to help increase student interest in learning basic neuroanatomy. Undergraduate students provided anonymous quantitative evaluations of both exercises. The feedback data suggest that students found both exercises engaging. The data also suggest that the first exercise increased student interest in learning more about neuroanatomy in general, while the second provided useful practice in identifying major neuroanatomical structures. Overall, the data suggest that these exercises may be a useful addition to courses that introduce or review neuroanatomical concepts. PMID:23805058

    Long before C P Snow's two cultures, there was only one. Its supreme embodiment was the great Renaissance master Leonardo da Vinci. Da Vinci saw no barriers between art and science (or what was known as natural philosophy back in the 16th century). His journals were filled with sketches, ideas and observations that testify to the polymath nature of Da Vinci's ingenuity. Da Vinci used artistic inspiration as a path to his inventions, and the observation of the natural world as an intrinsically artistic undertaking. He made thousands of blueprints outlining some of the most impressive inventions ever conceptualized - flying machines, bridges, calculators, tanks, solar-power cells. Most were impractical, few every saw the light of day, but all bore the mark of the master's infinite inventive powers.

Если в конце 20 века у пациентов был выбор хирургического вмешательства в виде открытого оперативного, либо более малоинвазивного метода лапароскопического вида вмешательства, то благодаря прорыву в сфере хирургических технологий, в начале 21 века появился новый аппарат, который дает наименее инвазивный вариант лечения для сложных оперативных вмешательств – Робот-ассистированная хирургическая система «da Vinci»...

    During the autumn of 2004, a team of 3D imaging scientists from the National Research Council of Canada (NRC) was invited to Paris to undertake the 3D scanning of Leonardo's most famous painting. The objective of this project was to scan the Mona Lisa, obverse and reverse, in order to provide high-resolution 3D image data of the complete painting to help in the study of the structure and technique used by Leonardo. Unlike any other painting scanned to date, the Mona Lisa presented a unique research and development challenge for 3D imaging. This paper describes this challenge and presents results of the modeling and analysis of the 3D and color data.

    Physics textbooks often present items of disciplinary knowledge in a sequential order of topics of the theory under instruction. Such presentation is usually univocal, that is, isolated from alternative claims and contributions regarding the subject matter in the pertinent scientific discourse. We argue that comparing and contrasting the contributions of scientists addressing similar or the same subject could not only enrich the picture of scientific enterprise, but also possess a special appealing power promoting genuine understanding of the concept considered. This approach draws on the historical tradition from Plutarch in distant past and Koyré in the recent history and philosophy of science. It gains a new support in the discipline-culture structuring of the physics curriculum, seeking cultural content knowledge (CCK) of the subject matter. Here, we address two prominent individuals of Italian Renaissance, Leonardo and Galileo, in their dealing with issues relevant for introductory science courses. Although both figures addressed similar subjects of scientific content, their products were essentially different. Considering this difference is educationally valuable, illustrating the meaning of what students presently learn in the content knowledge of mechanics, optics and astronomy, as well as the nature of science and scientific knowledge.
