Human NK cells: from HLA class I-specific killer Ig-like receptors to the therapy of acute leukemias
No full textOver the past 20 years, major progress has been made in our understanding of natural killer (NK) cells. It has become clear that NK cells are regulated by a number of receptors with opposite functions that finely tune potent effector functions such as cytolytic activity and release of cytokines that play a major role in inflammation and immunoregulation. This review traces the major advances in human NK cell biology from the original discovery of human leukocyte antigen class I-specific inhibitory receptors to recent groundbreaking clinical applications. These, in turn, led to major achievements and further expectations in the cure of high risk of otherwise fatal leukemias. It has become evident that there is a role of donor-derived 'alloreactive' NK cells in eradicating acute myeloid (and now also lymphoid) leukemias in the T-cell-depleted haploidentical hemopoietic stem cell transplantation setting. The key role played also in preventing graft rejection and graft versus host disease renders alloreactive NK cells an ideal tool for successful haploidentical hematopoietic stem cell transplantation
Alloreactive natural killer cells in targeting high-risk leukaemias.
No full textNatural killer (NK) cells express surface receptors that regulate potent effector functions, such as cytolytic activity and release of cytokines, which play a central role in inflammatory response and immunoregulation. In this paper, major advances are outlined from the original discovery of HLA-class I-specific inhibitory receptors in humans to recent, particularly successful, clinical applications in the cure of high-risk, otherwise fatal leukaemias. The central role of donor-derived "alloreactive" NK cells in eradicating leukaemic cells in the T-cell-depleted haploidentical haematopoietic stem cell transplantation setting became evident. Since alloreactive NK cells seem to play a key role also in preventing graft rejection and graft-vs-host disease, they may be an ideal tool to treat high-risk leukaemias in the haematopoietic stem cell transplantation setting

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
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
