The Discovery of Pulmonary Circulation: from Imhotep to William Harvey
The discovery of pulmonary circulation: From Imhotep to William Harvey Mohamed ElMaghawry1,2 *, Alberto Zanatta2, and Fabio Zampieri2 1: Department of Cardiology, Aswan Heart Centre, Aswan, Egypt 2: Department of Cardiac, Thoracic and Vascular Science, University of Padua, Padua, Italy * [email protected] Abstract In his quest to comprehend his existence, Man has long been exploring his outer world (macro- cosmos), as well as his inner world (micro-cosmos). In modern times, monmental advances in the fields of physics, chemistry, and other natural sciences have reflected on how we understand the anatomy and physiology of the human body and circulation. Yet, humanity took a long and winding road to reach what we acknowledge today as solid facts of cardiovascular physiology. In this article, we will review some of the milestones along this road. “The history of the pulmonary circulation provides a measure of Man’s thinking about himself and his place in the Universe.” (1) Alfred P. Fishman (1918-1990), president of American Physiological Society. The heart in ancient Egyptian medicine The ancient Egyptians considered the heart as the central organ of the body, both physiologically and spiritually. The earliest hieroglyphic depiction of the heart was as an organ with eight vessels attached to it (Figure 1A). After the third Dynasty, the heart was modified to a simpler jar-shape (Figure 1B) (2). The Smith papyrus (ca. 1600 BC) is the oldest known surgical treatise on trauma. It was named after Edwin Smith, the American Egyptologist who purchased the scroll in Luxor in 1862. Many historians believe that the text of the Smith papyrus was copied from a much older document originally written by Imhotep, the prominent high priest and physician of the Old Kingdom (ca.3000-2500 BC). -
Nomenclatura,Íntimamen- De Losnombrescientíficosnohasidounatareafácil
Los humanos clasificamos con el fin de lograr un orden y un manejo más fácil y adecuado de los objetos con los que La trabajamos. Entre los biólogos esta labor es fundamental para establecer códigos de comunicación que permitan ubicar el tipo de organismos que se investigan. Si bien las nomenclatura discusiones y sus resultados han sido parte de un lento y a veces complejo trabajo que ha ido evolucionando con los botánica en nuevos horizontes en la investigación, llegar a acuerdos en las comunidades científicas a nivel mundial en el terreno de los nombres científicos no ha sido una tarea fácil. la sistemática La taxonomía es la ciencia de la clasificación de los gru- pos de organismos, mientras la nomenclatura, íntimamen- te asociada a la taxonomía desde sus orígenes más remotos, del siglo XXI tiene como meta el poner un orden universal en la acepta- ción de nombres a diferentes niveles jerárquicos. Desde hace siglos ha sido imprescindible dar un nombre estable a toda especie y demás categorías que se describen a fin de que se le reconozca en un “idioma” universal. Las nomen- claturas taxonómicas botánica y zoológica se rigen por có- digos internacionales que se aprueban en congresos de este tipo. En general los códigos consisten en reglas, ar tícu- los y suplementos con recomendaciones, que en muchos casos son muy complejos. En el caso de las plantas, el código de referencia es el International Code of Nomenclature que se aprueba en los congresos internacionales periódicos de la International As- sociation for Plant Taxonomy. Las actualizaciones del código se llevan a cabo después de las reuniones de cada congreso, generalmente identificando el código con el nombre de la ciudad sede del congreso. -

Natural History Collections Glossary Bibliography Biographical Sketch Summary The oldest roots of biological systematics are found in folk taxonomies, which are nearly universally developed by humankind to cope with the diversity of the living world. The logical background to the first modern attempts to rationalize the classifications was provided by Aristotle's logic, as embodied in Cesalpino's 16th century classification of plants. Major advances were provided in the following century by Ray, who paved the way for the work of Linnaeus, the author of standard treatises still regarded as the starting point of modern classification and nomenclature. Important conceptual progress was due to the French comparative anatomists of the early 19th century UNESCO(Cuvier, Geoffroy Saint-Hilaire) – andEOLSS to the first work in comparative embryology of von Baer. Biological systematics, however, was still searching for a unifying principle that could provide the foundation for a natural, rather than conventional, classification.SAMPLE This principle wasCHAPTERS provided by evolutionary theory: its effects on classification are already present in Lamarck, but their full deployment only happened in the 20th century. -
Rules of Botanical Nomenclature
Taxonomy Prof.(Dr.) Punam Jeswal Head M.Sc semester II Botany Department Rules of Botanical Nomenclature Definition - Nomenclature is the art of naming of objects, which deals with the determination of a correct name to a known plant or to a known taxon. The names indeed correspond to the sentence, as both constitute meaningful collection of words. A name indicates a noun that helps in the quick identification, easy communication and economy of memory about the object to which it is concerned. Types of Names - The names according to their range of audience, language, territorial coverage and governance are of two types :- 1. Common or vernacular names. 2. International or scientific names. Common or Vernacular Names - These names are of the locals, by the locals, for the locals, in the local dialect. That is when a local plant is named by native people for the identification and communication to the other people of the same territory in their won local dialect, it is referred to as local or common or vernacular name. The fundamental demerits of this name are that they have limited audience, small territorial coverage and not governed under any set of principles or rules and even the same plant may have more than one name in the same locality. Another demerit of concern regarding these names is presence of synonyms in the languages therefore; the same plant may have a variety of names at different places in different languages. As for instance, mango(Mangifera indica) posses more than fifty names in Sanskrit only and lotus is known by more than two dozen names in Sanskrit and Hindi languages. -
Historical Review
1 Historical Review INTRODUCTION This chapter presents a brief historical review of progress in the field of plant water relations because the authors feel that it is impossible to fully understand the present without some knowledge of the past. As the Danish philosopher Kierkegaarde wrote, "Life can only be understood backward, but it can only be lived forward," and this also is true of science. The present generation needs to be reminded that some generally accepted concepts have their origin in ideas of 17th or 18th century writers and although others were suggested many decades ago, they were neglected until recently. As might be expected, the importance of water to plant growth was recog- nized by prehistoric farmers because irrigation systems already existed in Egypt, Babylonia (modern Iraq), and China at the beginning of recorded history, and the first European explorers found extensive irrigation systems in both North and South America. However, irrigation was not used extensively in agriculture in the United States until after the middle of the 19th century and little research on plant water relations occurred until the 20th century. Early Research Although plant water relations appear to have been the first area of plant physiology to be studied, progress was slow from Aristotle who died in 322 B.C. to the middle of the 19th century. According to Aristotle, plants absorbed their food ready for use from the soil, and plant nutrition was controlled by a soul or vital principle that ailowed plants to absorb only those substances useful in 2 1. Historical Review growth. This idea only began to be questioned in the 17th century by Jung, van Helmont, Mariotte, and others, and it ~ersistedinto the 19th century. -
Suppressing Synonymy with a Homonym: the Emergence of the Nomenclatural Type Concept in Nineteenth Century Natural History
Journal of the History of Biology (2016) 49:135–189 Ó The Author(s). This article is published with open access at Springerlink.com 2015 DOI 10.1007/s10739-015-9410-y Suppressing Synonymy with a Homonym: The Emergence of the Nomenclatural Type Concept in Nineteenth Century Natural History JOERI WITTEVEEN Descartes Centre for the History and Philosophy of the Sciences and the Humanities Utrecht University Utrecht The Netherlands E-mail: [email protected] Department of Philosophy and Religious Studies Utrecht University Utrecht The Netherlands Department of Psychology Utrecht University Utrecht The Netherlands Abstract. ‘Type’ in biology is a polysemous term. In a landmark article, Paul Farber (Journal of the History of Biology 9(1): 93–119, 1976) argued that this deceptively plain term had acquired three different meanings in early nineteenth century natural history alone. ‘Type’ was used in relation to three distinct type concepts, each of them associated with a different set of practices. Important as Farber’s analysis has been for the historiography of natural history, his account conceals an important dimension of early nineteenth century ‘type talk.’ Farber’s taxonomy of type concepts passes over the fact that certain uses of ‘type’ began to take on a new meaning in this period. At the closing of the eighteenth century, terms like ‘type specimen,’ ‘type species,’ and ‘type genus’ were universally recognized as referring to typical, model members of their encom- passing taxa. But in the course of the nineteenth century, the same terms were co-opted for a different purpose. As part of an effort to drive out nomenclatural synonymy – the confusing state of a taxon being known to different people by different names – these terms started to signify the fixed and potentially atypical name-bearing elements of taxa. -

La Vita E L'opera Botanica Di Andrea Cesalpino
SCHEDA DI APPROFONDIMENTO · I N S I G H T La vita e l’opera botanica di Andrea Cesalpino The life and botanical work of Andrea Cesalpino ndrea Cesalpino (Fig. 6) nacque nel 1525 Aad Arezzo. Poco si conosce sulla sua vita negli anni della sua gioventù; secondo fonti at- tendibili si sarebbe trasferito presto a Pisa (forse nel 1545) per seguire i corsi di quella Università, dove si sarebbe laureato in medicina intorno al 1551. A Pisa seguì le lezioni di botanica medica k di Ghini, che era appunto «Lettore de’ Semplici» e quando quest’ultimo si trasferì a Bologna nel 1555, Cesalpino lo sostituì nell’insegnamento della «materia medica» e nella conduzione del- l’orto botanico pisano, di cui terrà la guida for- male fi no al 1558, come «Prefetto» dell’orto. Con lo spostamento dell’orto botanico dalla sede ori- ginaria (presso l’arsenale) alla zona di S. Marta venne affi data di nuovo a Cesalpino la «prefettu- ra» dell’Orto che terrà dal 1563 al 1583. Nomi- nato «Professore ordinario di medicina pratica», continuò nell’insegnamento fi no al 1591 quando venne chiamato a Roma da Papa Clemente VIII per assumere la carica di insegnante di medicina alla «Sapienza» e di archiatra pontifi cio, e qui restò fi no alla sua morte, avvenuta nel 1603 (Vi- viani 1917; 1927; Moggi 1981; 2006; 2008b). Durante il periodo pisano Cesalpino svolse una intensa attività di studioso, di ricercatore e di insegnante ed effettuò frequenti viaggi in tutta la Toscana per incrementare le sue conoscenze sul- la fl ora locale. -

Plants Found in the Middle Parts of the State Grow Here, Excepting the Alpine Flowers
CULTIVATION BOTANY.— Wood grows here [Concord] with great rapidity; and it is supposed there is as much now as there was twenty years ago. Walden woods at the south, and other lots towards the southwest parts of the town, are the most extensive, covering several hundred acres of light-soil land. Much of the fuel, which is consumed, is, however brought from the neighbouring towns. The most common trees are the oak, pine, maple, elm, white birch, chestnut, walnut, &c., &c. Hemlock and spruce are very rare. The ornamental trees transplanted, in this as in most other towns, do not appear to have been placed with much regularity; but as they are, they contribute much to the comfort and beauty of the town. The elm, buttonwood, horse-chestnut, and fruit trees have very properly taken the place of sickly poplars, in ornamenting the dwellings. The large elm in front of the court-house, –the pride of the common,– is almost unrivalled in beauty. It is about “three score and ten,” but is still growing with youthful vigor and uniform rapidity. Dr. Jarvis, who is familiar with the botany of Concord, informs me, that “most of the plants found in the middle parts of the state grow here, excepting the alpine flowers. The extensive low lands produce abundantly the natural families of the aroideæ, typhæ, cyperoideæ, gramineæ, junci, corymbiferæ and unbelliferæ. These genera especially abound. There are also found, the juncus militaris (bayonet rush), on the borders of Fairhaven pond; cornus florida; lobelia carinalis (cardinal flower) abundant on the borders of the river; polygala cruciata, in the east parts of the town; nyssa villosa (swamp hornbeam) at the foot of Fairhaven hill.” The cicuta Americana (hemlock) grows abundant on the intervals. -

My recent trip to the northern slope of the Sierra Oscura in southeastern Socorro County leads to me to believe that E. coryi is not the appropriate name for these large, shrubby plants. The plant I encountered in the Sierra Oscura (R.C. Sivinski 7606 UNM) closely resembles one that I know fairly well from the northwestern part of the state – Ephedra viridis Coville. In This Issue — Ephedra viridis is a vivid green to yellowish-green shrub with broom-like twigs on thick, gray, woody stems from an individual caudex that is usually not rhizomatous (Figure 1.).
