    Atlas Of Pediatric Ocular Oncology

    No full text
    This atlas-book was conceived in the dark evenings during the Covid pandemic to keep the mind busy, not only mine but also the young residents of our clinic. The images that enrich each chapter are part of a life of over 30 years dedicated to ocular oncology, mainly of the pediatric age. A passion and commitment transmitted by my mentor Prof. Frezzotti who treated the first retinoblastoma in 1959. So here, I find myself collecting the most significant images of hundreds of clinical cases faced, diagnosed and treated over the years. Retinoblastoma is obviously the largest part of this atlas due to the over 900 cases observed and treated in Siena. It took almost 3 years...because unfortunately the time left to write, study and publish is the evening hours after long and tiring days of clinical care activities. My long friendship, collaboration and growth together with Paolo Galluzzi has allowed us to add to each chapter MRI notions useful in the differential diagnosis of various pathologies. My friend Rana’a helped correct some chapters and give his contribution on ocular mela- noma in pediatric age. Good friends and colleagues have been added among the collaborators for sending unu- sual and rare cases. I thank Tero Kivela, Sonia De Francesco, Tommaso Bacci, Marco Mazza, Mattia Pasti, Alfonso Cerase, Lucia Monti, Mario Fruschelli and Cristina Menicacci for their precious contributions. An affectionate thought goes to all the young residents who, with great enthusiasm, em- braced the topics assigned to them and carried out the various chapters with curiosity and interest. The drawings were all done by the talented resident Dimitris Pollalis who gave a truly artistic touch to this atlas. This book is dedicated to all ophthalmologists, of all ages, who are passionate, curious and fascinated by their work with the hope that the hundreds of images can help to recognize unusual and complex cases

    Heterogeneous and tissue-specific regulation of effector T cell responses by IFN-gamma during Plasmodium berghei ANKA infection.

    IFN-γ and T cells are both required for the development of experimental cerebral malaria during Plasmodium berghei ANKA infection. Surprisingly, however, the role of IFN-γ in shaping the effector CD4(+) and CD8(+) T cell response during this infection has not been examined in detail. To address this, we have compared the effector T cell responses in wild-type and IFN-γ(-/-) mice during P. berghei ANKA infection. The expansion of splenic CD4(+) and CD8(+) T cells during P. berghei ANKA infection was unaffected by the absence of IFN-γ, but the contraction phase of the T cell response was significantly attenuated. Splenic T cell activation and effector function were essentially normal in IFN-γ(-/-) mice; however, the migration to, and accumulation of, effector CD4(+) and CD8(+) T cells in the lung, liver, and brain was altered in IFN-γ(-/-) mice. Interestingly, activation and accumulation of T cells in various nonlymphoid organs was differently affected by lack of IFN-γ, suggesting that IFN-γ influences T cell effector function to varying levels in different anatomical locations. Importantly, control of splenic T cell numbers during P. berghei ANKA infection depended on active IFN-γ-dependent environmental signals--leading to T cell apoptosis--rather than upon intrinsic alterations in T cell programming. To our knowledge, this is the first study to fully investigate the role of IFN-γ in modulating T cell function during P. berghei ANKA infection and reveals that IFN-γ is required for efficient contraction of the pool of activated T cells

    Pelevin’s Trinity in the novel “t”: author – protagonist – reader

    No full text
    The article attempts to interpret Pelevin's artistic strategy in the novel "T" by exploring its subject organization and addressing the key problems of the author, the protagonist, and the reader as they are seen by the researcher. The article analyzes the peculiarities of constructing the narrative reality in the novel "T", and goes on to discuss Pelevin's philosophic models of the development of the humankind, and the emergence of his new anthropology

    DNA fusion gene vaccination mobilizes effective anti-leukemic cytotoxic T lymphocytes from a tolerized repertoire

    No full text
    The majority of known human tumor-associated antigens derive from non-mutated self proteins. T cell tolerance, essential to prevent autoimmunity, must therefore be cautiously circumvented to generate cytotoxic T cell responses against these targets. Our strategy uses DNA fusion vaccines to activate high levels of peptide-specific CTL. Key foreign sequences from tetanus toxin activate tolerance-breaking CD4+ T cell help. Candidate MHC class Ibinding tumor peptide sequences are fused to the C terminus for optimal processing and presentation. To model performance against a leukemia-associated antigen in a tolerized setting, we constructed a fusion vaccine encoding an immunodominant CTL epitopederived from Friend murine leukemia virus gag protein (FMuLVgag) and vaccinated tolerant FMuLVgag-transgenic (gag-Tg) mice. Vaccination with the construct induced epitopespecificIFN-c-producing CD8+ T cells in normal and gag-Tg mice. The frequency and avidity of activated cells were reduced in gag-Tg mice, and no autoimmune injury resulted. However, these CD8+ T cells did exhibit gag-specific cytotoxicity in vitro and in vivo. Also, epitope-specific CTL killed FBL-3 leukemia cells expressing endogenous FMuLVgag antigen and protected against leukemia challenge in vivo. These results demonstrate a simple strategy to engage anti-microbial T cell help to activate epitope-specific polyclonal CD8+ T cell responses from a residual tolerized repertoire

    Born and raised in Lynn, T Nash grew up in East Lynn on Alley Street and then later in West Lynn. A 1992 graduate of Lynn Technical High School and 1995 graduate of North Shore Community College, Nash has spent a life in childcare, education, nursing, and elder care. He is a member of North Shore Pride and Chairperson for the Lynn Pride Flag Raising. He is the proud parent of an adult daughter and five-year-old son, who she and her partner are raising in Salem. A self-described “bully” as a teen, Nash explains how violence and alcoholism shaped her childhood. T discusses the long process of growing comfortable with his sexual and gender identity as a lesbian and trans-man. T speaks fondly about Fran’s Place and enthusiastically about the victory of marriage equality. T is the author of a book about caregiving called "Try Kindness.
