Tila, asuminen ja arkkitehtuuri : Henri Lefebvren teoria tilasta ja tilan tuottamisesta

2015

Tämän tutkielman aiheena on tilan (l ́espace) käsite ranskalaisen filosofin ja marxilaisena yhteiskuntateoreetikkona tunnetun Henri Lefebvren (1901–1991) ajattelussa. Lefebvre, jonka pääteos La Production de l'espace (”Tilan tuottaminen”) ilmestyi vuonna 1974, on yksi keskeisin 1900-luvun loppupuoliskolla yhteiskuntatieteissä tapahtuneen niin sanotun tilallisen käänteen taustateoreetikoista sekä yksi kaikista perusteellisimmin tilan käsitteen parissa työskennellyt filosofi. Tutkielmani pääkysymyksen muodostaa tilan ja tuotannon väliseen suhteen ongelma Lefebvrellä. Selvitän tutkielmassani miten Lefebvren tilan tuottamisen teoria rakentuu, ja miten se kehittyy teoreettiselta …

Immune pathway upregulation and lower genomic instability distinguish EBV-positive nodal T/NK-cell lymphoma from ENKTL and PTCL-NOS

2022

Primary Epstein-Barr virus (EBV)-positive nodal T/NK-cell lymphoma (PTCL-EBV) is a poorly understood disease which shows features resembling extranodal NK/T-cell lymphoma (ENKTL) and is currently not recognized as a distinct entity but categorized as a variant of primary T-cell lymphoma not otherwise specified (PTCL-NOS). Herein, we analyzed copynumber aberrations (n=77) with a focus on global measures of genomic instability and homologous recombination deficiency and performed gene expression (n=84) and EBV miRNA expression (n=24) profiling as well as targeted mutational analysis (n=16) to further characterize PTCL-EBV in relation to ENKTL and PTCL-NOS. Multivariate analysis revealed that …

MALATTIA DI KAWASAKI E MAS INDOTTA DA INFEZIONE DA EBV IN PAZIENTE CON LINFOISTIOCITOSI EMOFAGOCITICA DI TIPO 2

2019

L’HLH, rara patologia da alterata risposta infiammatoria sistemica, presenta elevata mortalità, se non diagnosticata e trattata tempestivamente. Il quadro clinico è caratterizzato da febbre elevata persistente, epatosplenomegalia, citopenia di almeno due linee cellulari, linfoadenopatia generalizzata, rash, iperferritinemia, ipertrigliceridemia, ipofibrinogenemia, ipertransaminasemia e alterazioni della coagulazione. La HLH è divisa in primaria o familiare (autosomica recessiva) e secondaria (S. Autoinfiammatorie, infezioni, trapianti, ecc). La terapia si basa su chemioterapia (protocollo HLH94 e HLH2004) e, per le HLH familiari, e trapianto di midollo osseo. Fra le forme familiari, il tipo…

Interleukin-10 and interleukin-18 promoter polymorphisms in an Italian cohort of patients with undifferentiated carcinoma of nasopharyngeal type.

2004

Purpose: Cytokines such as IL-10 and IL-18 seem to be involved in the inflammatory response of undifferentiated carcinoma of nasopharyngeal type (UCNT). The aim of this study was to evaluate the correlation between functional single nucleotide polymorphisms (SNPs) in the promoter region of IL-10 and IL-18 genes and the virological and clinical characteristics in a large case series of Caucasian patients suffering from UCNT, a tumor regularly associated with the Epstein Barr Virus (EBV). Methods: Eighty-nine patients with histologically confirmed UCNT and 130 healthy donors were included in our study. DNA was examined for the polymorphisms of IL-10 gene at positions –1082, −819, −592 by dire…

A Novel Risk Locus at 6p21.3 for Epstein-Barr Virus-Positive Hodgkin Lymphoma

2015

Abstract Background: A proportion of the genetic variants involved in susceptibility to Hodgkin lymphoma differ by the tumor's Epstein–Barr virus (EBV) status, particularly within the MHC region. Methods: We have conducted an SNP imputation study of the MHC region, considering tumor EBV status in 1,200 classical Hodgkin lymphoma (cHL) cases and 5,726 control subjects of European origin. Notable findings were genotyped in an independent study population of 468 cHL cases and 551 controls. Results: We identified and subsequently replicated a novel association between a common genetic variant rs6457715 and cHL. Although strongly associated with EBV-positive cHL [OR, 2.33; 95% confidence interva…

Burkitt lymphoma with a granulomatous reaction: an M1/Th1‐polarised microenvironment is associated with controlled growth and spontaneous regression

2021

Aims Burkitt lymphoma (BL) is an aggressive B-cell lymphoma that, in some instances, may show a granulomatous reaction associated with a favourable prognosis and occasional spontaneous regression. In the present study, we aimed to define the tumour microenvironment (TME) in four such cases, two of which regressed spontaneously. Methods and results All cases showed aggregates of tumour cells with the typical morphology, molecular cytogenetics and immunophenotype of BL surrounded by a florid epithelioid granulomatous reaction. All four cases were Epstein-Barr virus (EBV)-positive with type I latency. Investigation of the TME showed similar features in all four cases. The analysis revealed a p…

Umbilical cord blood transplantation in adults with advanced hodgkin's disease: high incidence of post-transplant lymphoproliferative disease

2016

We report the outcome of 30 consecutive patients with Hodgkin disease (HD) who underwent single-unit UCBT. Most (90%) patients had failed previous autologous hematopoietic stem cell transplantation. The conditioning regimens were based on combinations of thiotepa, busulfan, cyclophosphamide or fludarabine, and antithymocyte globulin. The cumulative incidence (CI) of myeloid engraftment was 90% [95% confidence interval (C.I.), 74-98%] with a median of 18 d (range, 10-48). CI of acute graft-versus-host disease (GvHD) grades II-IV was 30% (95% C.I., 17-44%), while the incidence of chronic GVHD was 42% (95% C.I., 23-77%). The non-relapse mortality (NRM) at 100 d and 4 yr was 30% (95% C.I., 13-4…

Exposure to UV radiation and risk of Hodgkin lymphoma: A pooled analysis

2013

Ultraviolet radiation (UVR) exposure has been inversely associated with Hodgkin lymphoma (HL) risk, but only inconsistently, only in a few studies, and without attention to HL heterogeneity. We conducted a pooled analysis of HL risk focusing on type and timing of UVR exposure and on disease subtypes by age, histology, and tumor-cell Epstein-Barr virus (EBV) status. Four case-control studies contributed 1320HLcasesand 6381 controls. We estimated lifetime, adulthood, and childhood UVR exposure and history of sunburn and sunlamp use. We used 2-stage estimation with mixed-effects models and weighted pooled effect estimates by inverse marginal variances. We observed statistically significant inv…
