Single-Molecule Mechanoresistivity by Intermetallic Bonding.

The metal-electrode interface is key to unlocking emergent behaviour in all organic electrified systems, from battery technology to molecular electronics. In the latter, interfacial engineering has enabled efficient transport, higher device stability, and novel functionality. Mechanoresistivity - the change in electrical behaviour in response to a mechanical stimulus and a pathway to extremely sensitive force sensors - is amongst the most studied phenomena in molecular electronics, and the molecule-electrode interface plays a pivotal role in its emergence, reproducibility, and magnitude.

Embodied (4EA) cognitive computational neuroscience.

I argue that ideas and models about the mechanisms of neural computation and representation - including computational architecture, representational format, encoding schemes, learning methods, computation-representation coordination, and substrate-dependent aspects - must be tested by studying embodied neural systems. Thus, cognitive computational neuroscience - the study of neural computations over neural representations - must be an embodied research program.

Decoupled High-Mobility Graphene on Cu(111)/Sapphire via Chemical Vapor Deposition.

The growth of high-quality graphene on flat and rigid templates, such as metal thin films on insulating wafers, is regarded as a key enabler for technologies based on 2D materials. In this work, the growth of decoupled graphene is introduced via non-reducing low-pressure chemical vapor deposition (LPCVD) on crystalline Cu(111) films deposited on sapphire. The resulting film is atomically flat, with no detectable cracks or ripples, and lies atop of a thin CuO layer, as confirmed by microscopy, diffraction, and spectroscopy analyses.

Fourier Transform Infrared Spectroscopy Application for Outbreak Typing in a Referral Intensive Care Unit: Phylogenetic Analysis and Clustering Cut-Off Definition.

Recently has emerged as a multi-resistant fungal pathogen, with a significant clinical impact, and is able to persist for a long time on human skin and hospital environments. It is a critical issue on the WHO fungal priority list and therefore it is fundamental to reinforce hospital surveillance protocols to limit nosocomial outbreaks. The purpose of this study was to apply Fourier transform infrared spectroscopy (FT-IR) to investigate the phylogenetic relationships among isolated strains from a outbreak at the University Intensive Care Unit of a Tertiary University hospital in Turin (Italy).

Optoelectronics is a valuable solution to scale up wireless links frequency to sub-THz in the next generation antenna systems and networks. Here, we propose a low-power consumption, small footprint building block for 6 G and 5 G new radio wireless transmission allowing broadband capacity (e.g.

WORDS: A New Verbal Memory Test to Evaluate Cognitive Health in a Zambian School-aged Population.

Objective: The paucity of psychometric instruments is one of the challenges preventing the effective implementation of child cognitive health testing in Sub-Saharan countries. WORDS is a new memory assessment tool originally validated in a Zambian school-aged population.

Design: WORDS involves the standardized administration of a multitrial, verbal, free recall task with acquisition and immediate recall of a structured list of 16 words, followed by a second acquisition and delayed recall after a five-minute interference.

Signatures of Extreme Longevity: A Perspective from Bivalve Molecular Evolution.

Among Metazoa, bivalves have the highest lifespan disparity, ranging from 1 to 500+ years, making them an exceptional testing ground to understand mechanisms underlying aging and the evolution of extended longevity. Nevertheless, comparative molecular evolution has been an overlooked approach in this instance. Here, we leveraged transcriptomic resources spanning 30 bivalve species to unravel the signatures of convergent molecular evolution in four long-lived species: Margaritifera margaritifera, Elliptio complanata, Lampsilis siliquoidea, and Arctica islandica (the latter represents the longest-lived noncolonial metazoan known so far).

The impact of the second COVID-19 lockdown on anxiety and depressive symptoms in pregnant women: A case study of pregnant women in northern Italy.

Background: the different lockdown phases due to COVID-19 may have negatively impacted pregnant women's mental health. Concerning antenatal stress, most studies focused more on the effect of pandemic onset than on the impact of the following phases and restrictions.

Aim: the present study aimed to assess levels of anxiety and depression in a group of Italian pregnant women during the second COVID-19 phase and possible risk factors.

Design of Pyrrole-Based Gate-Controlled Molecular Junctions Optimized for Single-Molecule Aflatoxin B1 Detection.

Food contamination by aflatoxins is an urgent global issue due to its high level of toxicity and the difficulties in limiting the diffusion. Unfortunately, current detection techniques, which mainly use biosensing, prevent the pervasive monitoring of aflatoxins throughout the agri-food chain. In this work, we investigate, through ab initio atomistic calculations, a pyrrole-based Molecular Field Effect Transistor (MolFET) as a single-molecule sensor for the amperometric detection of aflatoxins.

Socio-demographic and clinical characteristics of SARS-CoV-2-positive psychiatric in-patients: A case-control study in the psychiatric wards of a Great Metropolitan Hospital in Milan.

During the first Covid-19 outbreak, the Niguarda Hospital of Milan featured two Psychiatry wards, one for SARS-CoV-2 positive patient and one for patients requiring hospitalization and negative for SARS-CoV-2. The two groups of patients were compared and were similar in distribution of psychiatric diagnosis, duration of illness and previous hospitalizations. SARS-CoV-2 positive participants had a lower severity of symptoms both at admission and discharge, a lower frequency of psychotic symptoms and substance intoxication at admission.

Germline-related molecular phenotype in Metazoa: conservation and innovation highlighted by comparative transcriptomics.

Background: In Metazoa, the germline represents the cell lineage devoted to the transmission of genetic heredity across generations. Its functions intuitively evoke the crucial roles that it plays in organism development and species evolution, and its establishment is tightly tied to animal multicellularity itself. The molecular toolkit expressed in germ cells has a high degree of conservation between species, and it also shares many components with the molecular phenotype of some animal totipotent cell lineages, like planarian neoblasts and sponge archaeocytes.

Is Overtaking Group B in Early-Onset Neonatal Sepsis.

The widespread use of intrapartum antibiotic prophylaxis (IAP) to prevent group B (GBS) early-onset sepsis (EOS) is changing the epidemiology of EOS. Italian prospective area-based surveillance data (from 1 January 2016 to 31 December 2020) were used, from which we identified 64 cases of culture-proven EOS (, = 39; GBS, = 25) among 159,898 live births (annual incidence rates of 0.24 and 0.

Moiré-Induced Transport in CVD-Based Small-Angle Twisted Bilayer Graphene.

To realize the applicative potential of 2D twistronic devices, scalable synthesis and assembly techniques need to meet stringent requirements in terms of interface cleanness and twist-angle homogeneity. Here, we show that small-angle twisted bilayer graphene assembled from separated CVD-grown graphene single-crystals can ensure high-quality transport properties, determined by a device-scale-uniform moiré potential. Via low-temperature dual-gated magnetotransport, we demonstrate the hallmarks of a 2.

Situated Neural Representations: Solving the Problems of Content.

Situated approaches to cognition maintain that cognition is embodied, embedded, enactive, and affective (and extended, but that is not relevant here). Situated approaches are often pitched as alternatives to computational and representational approaches, according to which cognition is computation over representations. I argue that, far from being opposites, situatedness and neural representation are more deeply intertwined than anyone suspected.

BASE: A novel workflow to integrate nonubiquitous genes in comparative genomics analyses for selection.

Inferring the selective forces that orthologous genes underwent across different lineages can help us understand the evolutionary processes that have shaped their extant diversity and the phenotypes they underlie. The most widespread metric to estimate the selection regimes of coding genes-across sites and phylogenies-is the ratio of nonsynonymous to synonymous substitutions (d/d, also known as ). Nowadays, modern sequencing technologies and the large amount of already available sequence data allow the retrieval of thousands of orthologous genes across large numbers of species.

Anxiety, Depression and Risk of Post-Traumatic Stress Disorder in Health Workers: The Relationship with Burnout during COVID-19 Pandemic in Italy.

During the COVID-19 pandemic, healthcare workers (HW) have faced an extremely difficult work environment, with an increased workload and traumatic events. Our study aimed to investigate the impact of COVID-19 pandemic on HW's mental wellbeing. We analyzed the correlations between levels of burnout and other mental health disorders and we searched for the presence of specific risk factors of post-traumatic symptomatology related to the pandemic.

Maternal Carriage in Late-Onset Group B Streptococcus Disease, Italy.

We retrospectively investigated mother-to-infant transmission of group B (GBS) in 98 cases of late-onset disease reported during 2007–2018 by a network in Italy. Mothers with full assessment of vaginal/rectal carriage tested at prenatal screening and at time of late onset (ATLO) were included. Thirty-three mothers (33.

Emergency Psychiatric Consultations During and After the COVID-19 Lockdown in Italy. A Multicentre Study.

The aim was to analyse the psychiatric consultations in nine Italian hospital emergency departments, by comparing the lockdown and post-lockdown periods of 2020 with the equivalent periods of 2019. Characteristics of psychiatric consultations, patients, and drug prescriptions were analyzed. Joinpoint models were used to identify changes in the weekly trend of consultations.

Bivalve Molluscs as Model Systems for Studying Mitochondrial Biology.

The class Bivalvia is a highly successful and ancient taxon including ∼25,000 living species. During their long evolutionary history bivalves adapted to a wide range of physicochemical conditions, habitats, biological interactions, and feeding habits. Bivalves can have strikingly different size, and despite their apparently simple body plan, they evolved very different shell shapes, and complex anatomic structures.

Circulating Inflamma-miRs as Potential Biomarkers of Cognitive Impairment in Patients Affected by Alzheimer's Disease.

Alzheimer's disease (AD), the most prevalent neurodegenerative disease in the growing population of elderly people, is still lacking minimally-invasive circulating biomarkers that could facilitate the diagnosis and the monitoring of disease progression. MicroRNAs (miRNAs) are emerging as tissue-specific and/or circulating biomarkers of several age-related diseases, but evidence on AD is still not conclusive. Since a systemic pro-inflammatory status was associated with an increased risk of AD development and progression, we focused our investigation on a subset of miRNAs modulating the inflammatory process, namely inflamma-miRNAs.

Early germline differentiation in bivalves: TDRD7 as a candidate investigational unit for Ruditapes philippinarum germ granule assembly.

The germline is a key feature of sexual animals and the ways in which it separates from the soma differ widely across Metazoa. However, at least at some point during germline differentiation, some cytoplasmic supramolecular structures (collectively called germ plasm-related structures) are present and involved in its specification and/or differentiation. The factors involved in the assembly of these granular structures are various and non-ubiquitous among animals, even if some functional patterns and the presence of certain domains appear to be shared among some.

Parkinson's disease and virtual reality rehabilitation: cognitive reserve influences the walking and balance outcome.

Introduction: Parkinson's disease (PD) is a neurodegenerative pathology characterized by motor and non-motor symptoms that often lead to several impairments. Many studies show the efficacy of different rehabilitation protocols aimed to improve balance and gait functions in PD patients. However, multiple factors may influence rehabilitation outcome.

Mitonuclear Coevolution, but not Nuclear Compensation, Drives Evolution of OXPHOS Complexes in Bivalves.

In Metazoa, four out of five complexes involved in oxidative phosphorylation (OXPHOS) are formed by subunits encoded by both the mitochondrial (mtDNA) and nuclear (nuDNA) genomes, leading to the expectation of mitonuclear coevolution. Previous studies have supported coadaptation of mitochondria-encoded (mtOXPHOS) and nuclear-encoded OXPHOS (nuOXPHOS) subunits, often specifically interpreted with regard to the "nuclear compensation hypothesis," a specific form of mitonuclear coevolution where nuclear genes compensate for deleterious mitochondrial mutations due to less efficient mitochondrial selection. In this study, we analyzed patterns of sequence evolution of 79 OXPHOS subunits in 31 bivalve species, a taxon showing extraordinary mtDNA variability and including species with "doubly uniparental" mtDNA inheritance.

Deterministic synthesis of CuS flakes assisted by single-layer graphene arrays.

The employment of two-dimensional materials, as growth substrates or buffer layers, enables the epitaxial growth of layered materials with different crystalline symmetries with a preferential crystalline orientation and the synthesis of heterostructures with a large lattice constant mismatch. In this work, we employ single crystalline graphene to modify the sulfurization dynamics of copper foil for the deterministic synthesis of large-area CuS crystals. Molecular dynamics simulations using the Reax force-field are used to mimic the sulfurization process of a series of different atomistic systems specifically built to understand the role of graphene during the sulphur atom attack over the Cu(111) surface.
