Potential involvement of IL-9 and Th9 cells in the pathogenesis of rheumatoid arthritis
2015
Objective IL-9 has been shown to be upregulated before the clinical onset of articular disease in RA. The exact role of IL-9 and Th9 cells in RA, however, has not yet been adequately studied. The aim of this study was to evaluate the expression of IL-9 and IL-9-expressing cells in RA patients. Methods IL-9, IL-9R, PU.1, IL-9, thymic stromal lymphopoietin (TSLP), IL-4 and TGF-β expression was assessed by real-time-PCR in the synovial tissues of RA and OA patients. IL-9, IL-9R, IL-4, TSLP and TGF-β were also investigated by immunohistochemistry. Peripheral CD4(+) T cell subsets were studied by flow cytometry analysis before and after incubation with citrullinated peptides. Results IL-9 was ov…
Associations of common breast cancer susceptibility alleles with risk of breast cancer subtypes in BRCA1 and BRCA2 mutation carriers
2014
Introduction More than 70 common alleles are known to be involved in breast cancer (BC) susceptibility, and several exhibit significant heterogeneity in their associations with different BC subtypes. Although there are differences in the association patterns between BRCA1 and BRCA2 mutation carriers and the general population for several loci, no study has comprehensively evaluated the associations of all known BC susceptibility alleles with risk of BC subtypes in BRCA1 and BRCA2 carriers. Methods We used data from 15,252 BRCA1 and 8,211 BRCA2 carriers to analyze the associations between approximately 200,000 genetic variants on the iCOGS array and risk of BC subtypes defined by estrogen re…
Autocrine production of interleukin-4 and interleukin-10 is required for survival and growth of thyroid cancer cells.
2006
AbstractAlthough CD95 and its ligand are expressed in thyroid cancer, the tumor cell mass does not seem to be affected by such expression. We have recently shown that thyroid carcinomas produce interleukin (IL)-4 and IL-10, which promote resistance to chemotherapy through the up-regulation of Bcl-xL. Here, we show that freshly purified thyroid cancer cells were completely refractory to CD95-induced apoptosis despite the consistent expression of Fas-associated death domain and caspase-8. The analysis of potential molecules able to prevent caspase-8 activation in thyroid cancer cells revealed a remarkable up-regulation of cellular FLIPL (cFLIPL) and PED/PEA-15, two antiapoptotic proteins whos…
Candida bloodstream infections in intensive care units: Analysis of the extended prevalence of infection in intensive care unit study
2011
Objectives: To provide a global, up-to-date picture of the prevalence, treatment, and outcomes of Candida bloodstream infections in intensive care unit patients and compare Candida with bacterial bloodstream infection. Design: A retrospective analysis of the Extended Prevalence of Infection in the ICU Study (EPIC II). Demographic, physiological, infection-related and therapeutic data were collected. Patients were grouped as having Candida, Gram-positive, Gram-negative, and combined Candida/bacterial bloodstream infection. Outcome data were assessed at intensive care unit and hospital discharge. Setting: EPIC II included 1265 intensive care units in 76 countries. Patients: Patients in partic…
Chemotherapy cardiotoxicity: cardioprotective drugs and early identification of cardiac dysfunction.
2016
Background: Chemotherapy cardiotoxicity is an emerging problem and it is very important to prevent cardiac dysfunction caused by anticancer drugs. The aim of this study was to assess the alterations of the cardiac function induced by chemotherapy in a follow-up of 2 years and to evaluate the cardioprotective role of angiotensin-converting enzyme inhibitors (ACEIs) in the prevention of cardiac dysfunction. Methods: A prospective study was carried out using patients with breast cancer (85 women; median age 57W12years) and other inclusion and exclusion criteria. On the basis of treatment, patients were divided into six groups: fluorouracil-epirubicincyclophosphamide, FEC (group A); FEC and tra…
Polyvascular subclinical atherosclerosis in familial hypercholesterolemia: The role of cholesterol burden and gender
2019
International audience; BACKGROUND AND AIM:Heterozygous familial hypercholesterolemia (HeFH) is a genetic disease characterized by a heterogeneous phenotype. The assessment of cardiovascular (CV) risk is challenging for HeFH. Cholesterol burden (CB) allows to estimate the lifelong exposure to high levels of cholesterol. The aim of this study was to analyze the distribution of subclinical atherosclerosis and the relationship between atherosclerosis and the CB in a sample of HeFH patients, focusing on sex-related differences.METHODS AND RESULTS:154 asymptomatic HeFH subjects underwent coronary-artery-calcium score (CACs) and Doppler ultrasound of carotid and femoral arteries. Yearly lipid pro…
High plasma levels of endothelin-1 enhance the predictive value of preclinical atherosclerosis for future cerebrovascular and cardiovascular events: …
2014
BACKGROUND AND PURPOSE: Clinical and experimental evidence suggests that endothelin-1 (Et-1) plays a role in cardiac and vascular disease. In the present study, we investigated the prognostic significance of Et-1 for cerebrovascular and cardiovascular outcome, in a 20-year follow-up. METHODS: We studied 82 originally healthy individuals, referred to our Unit of Cardiovascular Prevention, to evaluate the presence of asymptomatic carotid lesions. We subdivided these individuals into two groups, according to the plasma values of Et-1 (respectively ≤ or >2.7 pg/ml). Traditional cardiovascular risk factors were investigated, and by carotid ultrasound examination, we distinguished between normal …
Relationship between carotid intima-media thickness and non valvular atrial fibrillation type.
2015
OBJECTIVE: Carotid intima-media thickness (cIMT) is a surrogate marker of subclinical atherosclerosis and it is able to predict both coronary and cerebral vascular events. No data exist on the association between cIMT and non valvular atrial fibrillation (NVAF) type. We conduct this study with the aim to analyze the association between abnormal cIMT and NVAF type. METHODS: A cross-sectional study of the "Atrial fibrillation Registry for Ankle-brachial index Prevalence Assessment-Collaborative Italian Study (ARAPACIS)" has been performed. Among 2027 patients enrolled in the ARAPACIS, 673 patients, who underwent carotid ultrasound examination to assess cIMT, were included in the study. RESULT…
Coñece-lo mundo baixomedieval hispánico a través dos seus refráns: Los refranes que dizen las viejas tras el fuego
2011
O obxectivo do presente artigo é destacar brevemente algúns aspectos socioculturais, políticos e económicos da baixa Idade Media do reino de Castela (e, por extensión, nalgúns casos, dos restantes reinos cristiáns peninsulares), extraíbles da fosilización formal de enunciados pluriverbais que coñecemos como refráns. Baséase, primeiro, na consideración do refrán como reflexo, en maior ou menor medida, da sociedade do seu tempo (e tamén de épocas anteriores) e, segundo, como depositario non só do saber tradicional que se transmite de xeración en xeración, senón tamén da cultura socioeconómica, material e ambiental de épocas pretéritas. Para iso emprégase como corpus textual os Refranes que di…
Condition and Role of the Norman Cathedrals in the Fourteenth Century: Maintenance, Restoration and Renovation
2022
After conquering Sicily between 1061 and 1091, the Normans built new cathedrals that modified not only religious life, but also architecture and urban layout. Dramatic events, like wars, earthquakes, and fires, clumsy restorations and culpable inaccuracy have profoundly altered the appearance of Norman cathedrals. The aim of this paper is to analyse the state of conservation of the Cathedrals of Palermo, Monreale, Messina and Agrigento in the fourteenth century, when Sicily was profoundly affected by the war between the Angevins and the Aragonese that lasted ninety years and impoverished the island. The analysis of four case studies from the past will allow us to outline new perspectives fo…
