Cell-Mediated Immunity in Elite Controllers Naturally Controlling HIV Viral Load
Full text linkThe natural course of human immunodeficiency virus (HIV) infection is characterized by high viral load, depletion of immune cells, and immunodeficiency, ultimately leading to acquired immunodeficiency syndrome phase and the occurrence of opportunistic infections and diseases. Since the discovery of HIV in the early 1980s a naturally selected population of infected individuals has been emerged in the last years, characterized by being infected for many years, with viremia constantly below detectable level and poor depletion of immune cells. These individuals are classified as "elite controllers (EC) or suppressors" and do not develop disease in the absence of anti-retroviral therapy. Unveiling host factors and immune responses responsible for the elite status will likely provide clues for the design of therapeutic vaccines and functional cures. Scope of this review was to examine and discuss differences of the cell-mediated immune responses between HIV+ individuals with disease progression and EC
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Anatomia Foliar de Ocimum basilicum L. “Genovese” (Lamiaceae)

Taubaté,SP, Brasil.Centro Universitário SENAC. Campus Santo Amaro. São Paulo, SP, Brasil.FACIS. São Paulo, SP, Brasil.O controle botânico de uma espécie, principalmente o anatômico, é imprescindível para as indústrias farmacêuticas e de condimentos, porém, ainda são poucas as espécies destinadas a esses usos que tiveram suas características analisadas. Dentre elas as espécies de Ocimum, que apresentam complexidade devido à ampla ocorrência de variedades e cultivares. Este trabalho teve por objetivo caracterizar anatomicamente as folhas de Ocimum basilicum L. “Genovese” manjericão-italiano. Folhas das plantas cultivadas na UNITAU, Taubaté, SP, foram coletadas e submetidas a técnicas usuais de histologia. Em vista frontal, células epidérmicas de paredes anticlinais sinuosas em ambas as faces; são anfiestomáticas, com estômatos do tipo diacítico; apresentam numerosos tricomas tectores, unisseriados e pluricelulares, e glandulares sésseis, com mais frequência na região da nervura central, e glandulares peltados e capitados. O pecíolo, em vista transversal, tem secção côncavo- -convexa; epiderme unisseriada, cutícula lisa e delgada. Na epiderme superior, foram observados numerosos tricomas tectores unisseriados, uni a tricelulares, e glandulares, com pedicelo e glândula capitada unicelulares. O feixe vascular colateral em forma de arco raso aberto; e os elementos de vaso do metaxilema e protoxilema estão enfileirados, com poucas fibras esclerenquimáticas. Os caracteres observados complementam as informações para a espécie, descrevendo dados inéditos para o cultivar, possibilitando uma diagnose mais acuradae eficiente.The botanical control of species especially anatomical is necessary for the pharmaceutical and spices industries. Nevertheless, there are few species that had their characteristics analyzed. Among these aim Ocimum species, which have a complexity because of the widespread occurrence of varieties and cultivars. This work aimed to characterize anatomically the leaves of Ocimum basilicum L. `Genovese´. Leaves of plants grown at UNITAU, Taubate, SP, were collected and subjected to the usual techniques of histology. The leaves blades have in front view, epidermal cells sinuous anticlinal walls on both sides, amphistomatic, with diacytic stomata; uniseriate and multicellular trichomes, and sessile glandular trichomes, most frequently in the midrib region, and peltate and capitate glandular trichomes. The petiole, in transverse view, has a concave-convex section, uniseriate epidermis, cuticle smooth and thin, and at the upper epidermis numerous uniseriate trichomes were observed, as well as uni-tricelular and glandular trichomes with unicellular pedicel and unicellular capitate glands, collateral vascular bundle is present in the form of shallow open arc with few sclerenchyma fibers. The set of anatomical characters observed in this study complement the information for the species Ocimum basilicum, describing unpublished data to the cultivar. This enables a more accurate and efficient diagnosis of the cultivar
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
