Caminos de Montejo – Erinnerungen und Orte des Cimarrón Esteban Montejo

Esteban Montejo was the ‘Cimarrón’ in Miguel Barnets Book Biografía de un cimarrón. He spent most of the timeof his life in the rural parts of central Cuba, where he worked and lived on several sugar cane plantations. Those places, forming stations of his life, will be presented here. In some places of his life slavery is remembered until today, in others all traces have been lost

Rorschach\u27s Immunology: The Hematopoetic Cells

Art and science are often treated as separate disciplines in the modern world. Harkening back to the time when science was called “natural philosophy,” this project is intended to show the inherent compatibility between art, specifically painting and poetry, and science, specifically immunology. Hematopoietic (the source of the pun hematopoetic) cells all derive from a common progenitor in the human bone marrow; differentiated cells go on to inhabit a variety of areas in the body, from the blood to the lymphatics to other non-flowing tissues, either looking out for foreign material or being summoned when foreign material is found. For each of 11 of these cells, a canvas was painted, emphasizing an aspect of the cell’s physicality. Each canvas has a corresponding poem that puts the cell’s painting into the context of its lifestyle. Each poem is accompanied by an editorial commentary, further elucidating the cell’s purpose in the human immune system. The project suggests as much admiration for nature’s beauty—the appearance and purposefulness of form and function—as for humans’ imaginative abilities—our interpretation of appearances and creation of stories about them

Structure and specificity of T cell receptor gamma/delta on major histocompatibility complex antigen-specific CD3+, CD4-, CD8- T lymphocytes.

Analyses of TCR-bearing murine and human T cells have defined a unique subpopulation of T cells that express the TCR-gamma/delta proteins. The specificity of TCR-gamma/delta T cells and their role in the immune response have not yet been elucidated. Here we examine alloreactive TCR-gamma/delta T cell lines and clones that recognize MHC-encoded antigens. A BALB/c nu/nu (H-2d)-derived H-2k specific T cell line and derived clones were both cytolytic and released lymphokines after recognition of a non-classical H-2 antigen encoded in the TL region of the MHC. These cells expressed the V gamma 2/C gamma 1 protein in association with a TCR-delta gene product encoded by a Va gene segment rearranged to two D delta and one J delta variable elements. A second MHC-specific B10 nu/nu (H-2b) TCR-gamma/delta T cell line appeared to recognize a classical H-2D-encoded MHC molecule and expressed a distinct V gamma/C gamma 4-encoded protein. These data suggest that many TCR-gamma/delta-expressing T cells may recognize MHC-linked antigens encoded within distinct subregions of the MHC. The role of MHC-specific TCR-gamma/delta cells in immune responses and their immunological significance are discussed

Cineraria L. (Senecioneae, Asteraceae) - its taxonomy, phylogeny, phytogeography and conservation

Student no:7719196 PhD thesis 2005 Faculty of Science, School of Animal, Plant and Environmental Sciences.This study aimed to investigate the phylogeny of Cineraria L. to elucidate its position in the tribe Senecioneae (Asteraceae), to delimit its generic and species boundaries, explore species relationships (infrageneric structure) and produce a monograph of the genus. It also aimed to examine its distribution, phytogeographic affinities, levels of rarity and endemism in Cineraria, to identify some of the factors contributing to rarity in Cineraria and to highlight implications for conservation. Phylogenetic analyses were performed using morphological and molecular (DNA sequence) characters to elucidate relationships within the genus and between Cineraria and selected related genera in the subtribe Senecioninae. The phylogenetic species concept was applied - suites of diagnostic characters were used to characterise species. The phenetic approach, using Cluster Analysis and Principal Coordinates Analysis, was applied to investigate variation in two highly variable species, C. deltoidea Sond. and C. lobata L’Hér. Species distributions were mapped and the number of species per degree square was plotted for southern Africa to identify centres of diversity and endemism. Rare species were identified and categorised according to Rabinowitz’s criteria of geographic range, habitat specificity and local population size. Cineraria now has a more homogenous generic concept, characterised as herbs or subshrubs with palmately veined leaves, radiate, calyculate capitula, penicillate style apices and obovate, compressed cypselae with two distinct margins or wings and a substantial carpopodium. Eleven species have been removed from the genus and two new genera, Bolandia Cron and Oresbia Cron & B.Nord. have been established to accommodate three of the species. Two species have been reassigned to and another reinstated in Senecio L. The affinities of five species remain unresolved. Cineraria now comprises 35 species with four new subspecies and two new varieties recognised. Eight species have been placed in synonymy and five new species have been described during this revision. The status of C. deltoidea as a single, highly variable species, widespread throughout the eastern mountains of Africa, has been confirmed. Cineraria lobata has been shown to be a very variable species and the geographic and morphological variation has been formally (and informally) recognised. No infrageneric classification has been applied to Cineraria as a robust phylogeny of all the species has yet to be hypothesised. A southern African origin for Cineraria in the Western and/or Eastern Cape is postulated, based on the current distribution of the sister genus Bolandia and Cineraria mollis DC. iv Cineraria appears to have undergone rapid speciation fairly recently, as indicated by the lack of variation in the molecular data analysed, with reticulate evolution playing an important role in its evolutionary history (as seen by the lack of congruence between the chloroplast and nuclear DNA sequences). The centre of diversity of Cineraria is the KwaZulu-Natal Midlands, part of the Maputaland-Pondoland Centre of endemism in southern Africa. Cineraria has an afromontane affinity, and fifteen species endemic to specific mountains or regions of endemism and five near-endemics have been identified in Cineraria. Eleven species have been shown to be rare (in the sense of low abundance, restricted range and high habitat specificity), however only five are considered to be threatened as indicated by IUCN Red Data Criteria. However, at least seven species are Data Deficient and require further investigation. Causes of rarity in Cineraria are linked to narrow habitat specificity, particularly soil or rock type and/or altitudinal range

Margaret of Anjou : tradition and revision : a thesis presented in partial fulfilment of the requirements for the degree of Master of Arts in History at Massey University

Introduction: The Sources A broad consensus on the political activities of Margaret of Anjou exists in the scholarship of the late twentieth century; unfortunately it continues to be influenced by the traditional view of a virago who interfered in politics and encouraged faction in Lancastrian England. There are a number of reasons for this, not least that there is no detailed scholarly study of the queen1 1 A complete list of biographies of Margaret of Anjou is given in the bibliography. cf. T.F. Tout, 'Margaret of Anjou,' for a pithy and accurate commentary on Margaret's early biographers. Dictionary of National Biography, vol. 12, London: Oxford University Press, 1917. Originally published 1893. because she has been of peripheral interest to historians of Henry VI and the Wars of the Roses, although it is generally agreed that her participation was important, perhaps crucial; that she dominated her weak and compliant husband, Henry VI, and attempted to rule England herself, preferring factional government and civil war to reconciliation and rule by a representative council of lords under the king. Margaret of Anjou is not a sympathetic character, although she is sometimes portrayed as a tragic one. She has been savaged by Shakespeare from whom there is no appeal.2 2 Henry VI Part 3, Act 1, Scene 4: The Duke of York to Margaret of Anjou: 'She-wolf of France, but worse than wolves of France, Whose tongue more poisons than the adder's tooth!' 'O tiger's heart wrapp'd in a woman's hide!' 'But you are more inhuman, more inexorable - O, ten times more - than tigers of Hyrcania.' Margaret then stabs York and orders that his head be cut off. She was on the losing side of a struggle in which her Yorkist opponents were masters of the art of propaganda. The portrait of Margaret in the Yorkist chronicles has, in the main, been accepted by English authorities. 3 Patricia-Ann Lee, 'Reflections of Power: Margaret of Anjou and the Dark Side of Queenship,' Renaissance Quarterly, 39, (Summer 1986), for a concise, but not always accurate, summary of the views of English historians. French writers are a little kinder, since Margaret was a French princess and more to be pitied than blamed for becoming the wife of Henry VI. The Burgundians are less tolerant as they were allies of Edward IV and their chronicles reflect an Anglo-Burgundian (Yorkist) rather than an Anglo-French (Lancastrian) perspective; but they display the same Yorkist gloss that colours their English counterparts. History is not kind to failure. English historians, assessing the fifteenth century from a moral and patriotic viewpoint, had no difficulty in accepting the verdict of their Tudor predecessors that Margaret was a foreign French woman who interfered in the affairs of a country she neither valued nor understood. The tradition that Margaret dominated English politics from the time of her marriage is discredited, but her part in the political clash that culminated in the Wars of the Roses is still open to debate. Was she responsible for the demise of the Lancastrian dynasty or was she a victim of circumstance as the wife of an ineffectual king, the mother of a child heir and the leader by default of those who opposed Richard of York's bid for the throne
