Camouflage in arid environments: the case of Sahara-Sahel desert rodents

2020

Deserts and semi-deserts, such as the Sahara-Sahel region in North Africa, are exposed environments with restricted vegetation coverage. Due to limited physical surface structures, these open areas provide a promising ecosystem to understand selection for crypsis. Here, we review knowledge on camouflage adaptation in the Sahara-Sahel rodent community, which represents one of the best documented cases of phenotype-environment convergence comprising a marked taxonomic diversity. Through their evolutionary history, several rodent species from the Sahara-Sahel have repeatedly evolved an accurate background matching against visually-guided predators. Top-down selection by predators is therefore …

Extremophilic microbial communities on photovoltaic panel surfaces: a two‐year study

2020

Solar panel surfaces can be colonized by microorganisms adapted to desiccation, temperature fluctuations and solar radiation. Although the taxonomic and functional composition of these communities has been studied, the microbial colonization process remains unclear. In the present work, we have monitored this microbial colonization process during 24 months by performing weekly measurements of the photovoltaic efficiency, carrying out 16S rRNA gene high‐throughput sequencing, and studying the effect of antimicrobial compounds on the composition of the microbial biocenosis. This is the first time a long‐term study of the colonization process of solar panels has been performed, and our results…

Human γδ T-Cells: From Surface Receptors to the Therapy of High-Risk Leukemias

2018

γδ T lymphocytes are potent effector cells, capable of efficiently killing tumor and leukemia cells. Their activation is mediated by γδ T-cell receptor (TCR) and by activating receptors shared with NK cells (e.g., NKG2D and DNAM-1). γδ T-cell triggering occurs upon interaction with specific ligands, including phosphoantigens (for Vγ9Vδ2 TCR), MICA-B and UL16 binding protein (for NKG2D), and PVR and Nectin-2 (for DNAM-1). They also respond to cytokines undergoing proliferation and release of cytokines/chemokines. Although at the genomic level γδ T-cells have the potential of an extraordinary TCR diversification, in tissues they display a restricted repertoire. Recent studies have identified …

Vitamin D, allergies and asthma: focus on pediatric patients

2014

In recent years, the interest of the scientific world towards vitamin D gradually increased, and several studies have been conducted to dissect its possible role in modulating the development/course of allergic diseases. Also, Vitamin D supplementation has been assessed as a beneficial approach for treating allergies in some, but not all studies. We reviewed herein the available and relevant literature concerning the possible links between Vitamin D, its supplementation and allergic diseases. A literature search was made independently by the Authors, identifying articles for a narrative review. As per literature, Vitamin D plays a key role in calcium and phosphate metabolism, and it is esse…

«Spersonalizzazione e passivizzazione nel discorso giuridico amministrativo. Decodifica del testo e cooperazione. Italiano e spagnolo a confronto».

2008

The article examines the decode processes of the legal and administrative discourse, which user can be both the community, in its heterogeneity, both a private citizen. In particular, in the case of the administrative and of the legal discourse, the required feedback from the transaction comes from the user's linguistic skills implemented by the correct decoding of the normative text and by acting in accordance with the rules imposed. In this way, are established between the State and the citizen-receiver relationships of reciprocity underlying on the correct application of the Grice’s Cooperation maxims. Through the brief analysis on the syntax of the texts found for this work, it was foun…

Legislative Drafting e linguaggio: ipotesi di semplificazione del testo normativo

2016

l’ipotesi su cui si basa il presente articolo è che la disciplina della linguistica applicata possa dare un valido contributo al miglioramento della scrittura legislativa. recenti studi linguistici dimostrano che i legislative drafters spesso non colgono l’essenza dei concetti politici che hanno il compito di comunicare, proponendo un metodo attraverso il quale questi ultimi possano raggiungere tale obiettivo e di verificarne l’adeguatezza e rispondenza alla volontà del legislatore. l’analisi proposta dagli autori del contributo identifica nella chiarezza, nella precisione e nella univocità gli strumenti necessari al raggiungimento di tale scopo; applica prove linguistiche ad una serie di t…

Germinal matrix hemorrhage-intraventricular hemorrhage: pathogenesis and outcomes

2015

Germinal matrix hemorrhage-intraventricular hemorrhage (GMH-IVH) is one of the CNS injuries affecting preterm infants occurring in about 15%-20% of subjects weighing less than 1500 g. Currently, using ultrasonography, we recognize three grades of GMH-IVH. Grade I involving the subependymal parenchyma and/or extending in less than 10% of the ventricle, grade II with intraventricular bleeding not expanding in more than 50% of the ventricle, grade III characterized by consistent (> 50%)intraventricu- lar bleeding with ventricular dilatation. A concomitant intraparenchymal lesion (IPL), due to a venous infarction (ex grade IV), can be associated with any grade of IVH, worsening the prognosis. P…

INSAID Variant Classification and Eurofever Criteria Guide Optimal Treatment Strategy in Patients with TRAPS: Data from the Eurofever Registry

2021

Contains fulltext : 231528.pdf (Publisher’s version ) (Closed access) BACKGROUND: TNF receptor-associated periodic syndrome (TRAPS) is a rare autoinflammatory disease caused by dominant mutation of the TNF super family receptor 1A (TNFRSF1A) gene. Data regarding long-term treatment outcomes are lacking. OBJECTIVE: To assess correlations of genotype-phenotypes in patients with TRAPS, as defined by the International Study Group for Systemic Autoinflammatory Diseases (INSAID) classification and Eurofever criteria, with treatment responses. METHODS: Data from 226 patients with variants of the TNFRSF1A gene and enrolled in the Eurofever registry were classified according to the INSAID classifica…
