Future Scenarios of the Food System: Insights from the Consumers’ Perspective
A careful analysis of contemporary society shows a radical evolution of the role and function of consumption. So-called post-modernity, along with the technological, economic and social transformations that have brought it on, inaugurate a different way of conducting relationships, of existing and of consuming. So consumptions evolve, assuming new expressions in extremely heterogeneous ambits, including that of food consumptions. The past decades have witnessed a progressive increase in the complexity of food consumptions due to the affirmation of increasingly more differentiated trends sensitive to territorial specificity and, at the same time, open to the globalisation of tastes. This topic represents a theme as interesting from the scientific viewpoint as it is decisive from the perspective of implementing food marketing strategies. In this framework, studying food consumptions and the sources that influence them in order to comprehend motivations and significances, implicates reflecting on and investigating into the way these practises can be the object of conditioning mediated by business communication, social practises and practises among friends, or by particular socio-economic conditions...

Heterochromatic gene repression of the retinoic acid pathway in acute myeloid leukemia
Alteration of lineage-specific transcriptional programs for hematopoiesis causes differentiation block and promotes leukemia development. Here, we show that AML1/ETO, the most common translocation fusion product in acute myeloid leukemia (AML), counteracts the activity of retinoic acid (RA), a transcriptional regulator of myelopoiesis. AML1/ETO participates in a protein complex with the RA receptor alpha (RARα) at RA regulatory regions on RARβ2, which is a key RA target gene mediating RA activity/resistance in cells. At these sites, AML1/ETO recruits histone deacetylase, DNA methyltransferase, and DNA-methyl-CpG binding activities that promote a repressed chromatin conformation. The link among AML1/ETO, heterochromatic RARβ2 repression, RA resistance, and myeloid differentiation block is indicated by the ability of either siRNA-AML1/ETO or the DNA methylation inhibitor 5-azacytidine to revert these epigenetic alterations and to restore RA differentiation response in AML1/ETO blasts. Finally, RARβ2 is commonly silenced by hypermethylation in primary AML blasts but not in normal hematopoietic precursors, thus suggesting a role for the epigenetic repression of the RA signaling pathway in myeloid leukemogenesis. © 2007 by The American Society of Hematology
AML1/ETO causes heterochromatic gene silencing of the retinoic acid signaling pathway in Acute Myeloid Leukemia
Corpus callosum abnormalities: neuroimaging, cytogenetics and clinical characterization of a very large multicenter Italian series
Corpus callosum abnormalities (CCA) have an estimated prevalence
ranging from 0.3% up to 0.7% in patients undergoing brain imaging.
CCA can be identified incidentally, or can be part of a developmental
disease. We performed a retrospective study of 551 patients, identified
non-syndromic (NS) CCA and syndromic (S) CCA, reviewing clinical features,
neuroradiological aspects, genetic etiology, and chromosomal
microarray (CMA) results. Syndromic CCA subjects were prevalent
(60%) and they showed the most severe clinical features. Cortical malformations
and cerebellar anomalies were 23% of cerebral malformation
associated to CCA (plus), 23 and 14% respectively in syndromic forms. A clinical and/or genetic diagnosis was obtained in 37% of
syndromic CCA including chromosomal rearrangements on high-resolution
karyotype (18%), microdeletion/microduplication syndromes
(31%) and monogenic diseases (51%). Non-syndromic CCA anomalies
had mildest clinical features, although intellectual disability was present
in 49% of cases and epilepsy in 13%. CMA diagnostic rate in our
cohort of patients ranged from 11 to 23% (NS to S). A high percentage
of patients (76% 422/551) remain without a diagnosis. Combined high
resolution CMA studies and next-generation sequencing (NGS) strategies
will increase the probability to identify new causative genes of
CCA and to redefine genotype–phenotype correlation
Effects of pre‐operative isolation on postoperative pulmonary complications after elective surgery: an international prospective cohort study
We aimed to determine the impact of pre-operative isolation on postoperative pulmonary complications after elective surgery during the global SARS-CoV-2 pandemic. We performed an international prospective cohort study including patients undergoing elective surgery in October 2020. Isolation was defined as the period before surgery during which patients did not leave their house or receive visitors from outside their household. The primary outcome was postoperative pulmonary complications, adjusted in multivariable models for measured confounders. Pre-defined sub-group analyses were performed for the primary outcome. A total of 96,454 patients from 114 countries were included and overall, 26,948 (27.9%) patients isolated before surgery. Postoperative pulmonary complications were recorded in 1947 (2.0%) patients of which 227 (11.7%) were associated with SARS-CoV-2 infection. Patients who isolated pre-operatively were older, had more respiratory comorbidities and were more commonly from areas of high SARS-CoV-2 incidence and high-income countries. Although the overall rates of postoperative pulmonary complications were similar in those that isolated and those that did not (2.1% vs 2.0%, respectively), isolation was associated with higher rates of postoperative pulmonary complications after adjustment (adjusted OR 1.20, 95%CI 1.05-1.36, p = 0.005). Sensitivity analyses revealed no further differences when patients were categorised by: pre-operative testing; use of COVID-19-free pathways; or community SARS-CoV-2 prevalence. The rate of postoperative pulmonary complications increased with periods of isolation longer than 3 days, with an OR (95%CI) at 4-7 days or >= 8 days of 1.25 (1.04-1.48), p = 0.015 and 1.31 (1.11-1.55), p = 0.001, respectively. Isolation before elective surgery might be associated with a small but clinically important increased risk of postoperative pulmonary complications. Longer periods of isolation showed no reduction in the risk of postoperative pulmonary complications. These findings have significant implications for global provision of elective surgical care
DUNE Offline Computing Conceptual Design Report
International audienceThis document describes Offline Software and Computing for the Deep Underground Neutrino Experiment (DUNE) experiment, in particular, the conceptual design of the offline computing needed to accomplish its physics goals. Our emphasis in this document is the development of the computing infrastructure needed to acquire, catalog, reconstruct, simulate and analyze the data from the DUNE experiment and its prototypes. In this effort, we concentrate on developing the tools and systems thatfacilitate the development and deployment of advanced algorithms. Rather than prescribing particular algorithms, our goal is to provide resources that are flexible and accessible enough to support creative software solutions as HEP computing evolves and to provide computing that achieves the physics goals of the DUNE experiment
