Batista, "Immunological Synapse" English | 2009 | pages: 265 | ISBN: 3642038573, 364226185X | PDF | 6,1 mb The proper physiological functioning of most eukaryotic cells requires their assembly into multi-cellular tissues that form organized organ systems. Cells of the immune system develop in bone marrow and lymphoid organs, but as the cells mature they leave these organs and circulate as single cells. Antigen receptors (TCRs) of T cells search for membrane MHC proteins that are bound to peptides derived from infectious pathogens or cellular transformations. The detection of such speci?c peptide-MHC antigens initiates T cell activation, adhesion, and immune-effectors functions. Studies of normal and transformed T cell lines and of T cells from transgenic mice led to comprehensive understanding of the mole- lar basis of antigen-receptor recognition and signaling. In spite of these remarkable genetic and biochemical advances, other key physiological mechanisms that par- cipate in sensing and decoding the immune context to induce the appropriate cellular immune responses remain unresolved. TCRrecognition is tightly regulated to trigger sensitive but balanced T cell responses that result in the effective elimination of the pathogens while minimizing collateral damage to the host. The sensitivity of TCR recognition has to be properly tempered to prevent unintended activation by self-peptide-MHC complexes that cause autoimmune diseases. It is likely that once the TCR is engaged by a peptide- MHC and TCR signaling begins, additional regulatory mechanisms, involving other receptors, would increase the ?delity of the response. ![]() Free Download Immigrant, Montana By Amitava Kumar 2018 | 320 Pages | ISBN: 0525520759 | EPUB | 24 MB The author of the widely praisedLunch with a Bigotnow gives us a remarkable novel--reminiscent of Teju Cole, W. G. Sebald, John Berger--about a young new immigrant to the United States in search of love: across dividing lines between cultures, between sexes, and between the particular desires of one man and the women he comes to love.The young man is Kailash, from India. His new American friends call him Kalashnikov, AK-47, AK. He takes it all in his stride: he wants to fit in--and more than that, to shine. In the narrative of his years at a university in New York, AK describes the joys and disappointments of his immigrant experience; the unfamiliar political and social textures of campus life; the indelible influence of a charismatic professor--also an immigrant, his personal history as dramatic as AK's is decidedly not; the very different natures of the women he loved, and of himself in and out of love with each of them. Telling his own story, AK is both meditative and the embodiment of the enthusiasm of youth in all its idealism and chaotic desires. His wry, vivid perception of the world he's making his own, and the brilliant melding of story and reportage, anecdote and annotation, picture and text, give us a singularly engaging, insightful, and moving novel--one that explores the varieties and vagaries of cultural misunderstanding, but is, as well, an impassioned investigation of love. ![]() Free Download Gurdeep S. Mann, Joanne C. Blair, Anne S. Garden, "Imaging of Gynecological Disorders in Infants and Children" English | 2012 | pages: 258 | ISBN: 3662502003, 3540856013 | PDF | 14,9 mb This textbook provides a comprehensive review of gynecological imaging in infancy, childhood, and adolescence. Experts from the disciplines of pediatric radiology, gynecology, surgery, and endocrinology have come together to produce a textbook that, while written primarily from the perspective of the radiologist, will be of value to all professionals involved in the management of these patients. The normal development of the female reproductive tract is described in detail through embryological development, normal childhood appearances, and puberty. Congenital abnormalities are addressed in chapters reviewing structural abnormalities of the reproductive tract and disorders of sex development. A symptoms-based approach is followed in chapters devoted to the assessment of the patient with gynecological pain and disorders of menstruation. Disorders of the breast and the imaging of patients with gynecological neoplasia are considered in dedicated chapters. ![]() Free Download Caroline KEYZER, Pierre Alain Gevenois, "Imaging of Acute Appendicitis in Adults and Children" English | 2012 | pages: 244 | ISBN: 3662506378, 3642178715 | PDF | 13,3 mb This book is a comprehensive account of imaging of acute appendicitis and other appendiceal diseases. Background information is first provided on clinical presentation, perforation and negative appendectomy rates, and treatment options. The role of each imaging modality - radiography, ultrasound, CT, and MRI - is then considered separately in adults and children with suspected acute appendicitis. Many high-quality illustrations are included, and detailed information is provided on appropriate protocols and radiation saving. Further chapters addresses the spontaneously resolving and chronic appendicitis as well as other appendiceal lesions and review the findings of evidence-based medicine and cost-effectiveness analyses. Emergency physicians, pediatricians, surgeons, and radiologists will all find this book to be an excellent source of information and guidance. ![]() Free Download Lizzie Seal, "Imaginative Criminology: Of Spaces Past, Present and Future " English | ISBN: 152920268X | 2019 | 176 pages | PDF | 8 MB This distinctive and engaging book proposes an imaginative criminology, focusing on how spaces of transgression are lived, portrayed and imagined. These include spaces of control or confinement, including prison and borders, and spaces of resistance. Examples range from camps where asylum seekers and migrants are confined, to the exploration of deviant identities and the imagined spaces of surveillance and control in young adult fiction. Drawing on oral history, fictive portrayals, walking methodologies, and ethnographic and arts-based research, the book pays attention to issues of gender, sexuality, age, ethnicity, mobility and nationality as they intersect with lived and imagined space. ![]() Free Download Brent Cebul, "Illusions of Progress: Business, Poverty, and Liberalism in the American Century " English | ISBN: 1512823813 | 2023 | 432 pages | PDF | 6 MB Today, the word "neoliberal" is used to describe an epochal shift toward market-oriented governance begun in the 1970s. Yet the roots of many of neoliberalism's policy tools can be traced to the ideas and practices of mid-twentieth-century liberalism. ![]() Free Download Illiberal America: A History by Steven Hahn English | March 19, 2024 | ISBN: 0393635929 | True EPUB | 464 pages | 3.7 MB If your reaction to the January 6, 2021, insurrection at the Capitol was to think, 'That's not us,' think again: in Illiberal America, a Pulitzer Prize-winning historian uncovers a powerful illiberalism as deep seated in the American past as the founding ideals. ![]() Free Download Il Dentascan by Emanuele Neri , Silvio Mazziotti Italiano | PDF | 2012 | 49 Pages | ISBN : 8847027381 | 3.1 MB Il successo del trattamento chirurgico implantare è strettamente correlato a un'adeguata pianificazione dell'intervento e a una rigorosa valutazione preoperatoria. L'impiego di software di ricostruzione delle immagini dedicati alla diagnostica dentale, del tipo Dentascan, permette di ottenere ricostruzioni cross-section e simil-panoramiche (panorex) che misurano la quantità di tessuto osseo disponibile e definiscono accuratamente le strutture anatomiche contigue o la presenza di eventuali patologie associate. Questo manuale, dal taglio pratico e sintetico, affronta le principali questioni di ordine tecnico e metodologico relative allo studio TC mirato delle arcate dentarie e alla descrizione dell'anatomia e dei punti critici. Particolare rilievo è attribuito alle problematiche relative alla valutazione pre-implantologica, ai risultati e alle complicanze del trattamento, con cenni anche ad alcune indicazioni extra-implantari. ![]() Free Download If Warren Buffett Is President: Value-Based America by Bryan Andrew Madrid English | February 5, 2024 | ISBN: N/A | ASIN: B0CV3ZYW94 | 228 pages | EPUB | 4.36 Mb Forget Wall Street, the Oracle of Omaha takes on Pennsylvania Avenue in a whirlwind election! ![]() Free Download Anna Becker, "Identity, Power, and Prestige in Switzerland's Multilingual Education " English | ISBN: 3837666190 | 2023 | 270 pages | PDF | 2 MB Switzerland is known for its multilingualism, yet not all languages are represented equally in society. The situation is exacerbated by the influx of heritage languages and English through migration and globalization processes which challenge the traditional education system. This study is the first to investigate how schools in Grisons, Fribourg, and Zurich negotiate neoliberal forces leading to a growing necessity of English, a romanticized view on national languages, and the social justice perspective of institutionalizing heritage languages. It uncovers power and legitimacy issues and showcases students' and teachers' complex identities to advocate equitable multilingual education.
