Experiences and implications of the first wave of the COVID-19 emergency in Italy: a social science perspective
Background
Italy was among the first countries in the world to experience the devastating consequences of the COVID-19 emergency and suffered its consequences to a devastating scale. Understanding how the country got there in spite of a relatively well-resourced public and private health system in at least part of the country, is imperative to be able to operationalise any lessons learnt for future epidemics in Italy and beyond.
Methods
The paper reports the findings from a research scoping exercise conducted in Italy in 2020. We conducted extensive archival research and collected 29 testimonies either in writing or as semi-structured interviews. We sampled purposively with a stratification strategy in mind, specifically aiming to gain testimonies from different social groups, classes, ages, and nature of employment. Our sample also reflects the different experiences between the Northern and Southern regions, a divide that has long been economically and politically salient in the country.
Results
Evidence and considerations of epidemiological nature normally guide public health responses to crises. This study supports the idea that socio-economic, cultural and political factors also affect transmission outcomes. We highlight specifically the role that socioeconomic and health inequalities play in this respect, through factors such as overcrowded dwellings, lack of alternatives to in-person work, informal work set-ups, pervasive organised crime presence, poorly planned social support and communication strategies.
Conclusions
A socio-economic and political lens is needed in addition to an epidemiological one to fully understand the social experiences and implications of public health crises such as the COVID-19 pandemic and to devise effective response measures that are locally relevant and acceptable. Thus insights provided by multi-disciplinary task forces can render policymaking and social support interventions as well as communication strategies more effective
Biolayer Interferometry: Protein-RNA Interactions.
RNA-binding proteins often contain multiple RNA-binding domains connected by short flexible linkers. This domain arrangement allows the protein to bind the RNA with greater affinity and specificity than would be possible with individual domains and sometimes to remodel its structure. It is therefore important to understand how multiple modules interact with RNA because it is the modular nature of these proteins which specifies their biological function. This chapter is concerned with the use of biolayer interferometry to study protein-RNA interactions

Ketogenic diet improves behaviors in a maternal immune activation model of autism spectrum disorder
Prenatal factors influence autism spectrum disorder (ASD) incidence in children and can increase ASD symptoms in offspring of animal models. These may include maternal immune activation (MIA) due to viral or bacterial infection during the first trimesters. Unfortunately, regardless of ASD etiology, existing drugs are poorly effective against core symptoms. For nearly a century a ketogenic diet (KD) has been used to treat seizures, and recent insights into mechanisms of ASD and a growing recognition that immune/inflammatory conditions exacerbate ASD risk has increased interest in KD as a treatment for ASD. Here we studied the effects of KD on core ASD symptoms in offspring exposed to MIA. To produce MIA, pregnant C57Bl/6 mice were injected with the viral mimic polyinosinic-polycytidylic acid; after weaning offspring were fed KD or control diet for three weeks. Consistent with an ASD phenotype of a higher incidence in males, control diet-fed MIA male offspring were not social and exhibited high levels of repetitive self-directed behaviors; female offspring were unaffected. However, KD feeding partially or completely reversed all MIA-induced behavioral abnormalities in males; it had no effect on behavior in females. KD-induced metabolic changes of reduced blood glucose and elevated blood ketones were quantified in offspring of both sexes. Prior work from our laboratory and others demonstrate KDs improve relevant behaviors in several ASD models, and here we demonstrate clear benefits of KD in the MIA model of ASD. Together these studies suggest a broad utility for metabolic therapy in improving core ASD symptoms, and support further research to develop and apply ketogenic and/or metabolic strategies in patients with ASD
Role of Multiparametric-MRI in Bladder Cancer
Purpose of ReviewThis narrative review article aims to show the actual role of imaging, in particular MRI, and the role of VI-RADS Score, in recognition and follow-up of the tumor.Recent FindingsA team of professionals created VI-RADS with the goal of standardizing the acquisition and interpretation of multiparametric-MRI in bladder cancer.Bladder cancer is the most common cancer involving the urinary system. It is the fourth most common urological cancer in men and the second most frequent cancer affecting the urinary tract. Main risks factors are advanced age, male sex, and cigarette smoking. Bladder cancer ranges from unaggressive and usually non-invasive tumors that recur and commit patients to long-term invasive surveillance, to aggressive and invasive tumors with high disease-specific mortality. At the time of diagnosis, 70% of patients are experiencing non-muscle-invasive bladder cancer. Vesical imaging-reporting and data system score (VI-RADS) is a scoring system useful to standardize the approach to multiparametric-MRI interpretation, and reporting for bladder cancer
On the mechanism of calcium-dependent activation of NADPH oxidase 5 (NOX5)
It is now accepted that reactive oxygen species (ROS) are not only dangerous oxidative agents but also chemical mediators of the redox cell signaling and innate immune response. A central role in ROS-controlled production is played by the NADPH oxidases (NOXs), a group of seven membrane-bound enzymes (NOX1-5 and DUOX1-2) whose unique function is to produce ROS. Here, we describe the regulation of NOX5, a widespread family member present in cyanobacteria, protists, plants, fungi, and the animal kingdom. We show that the calmodulin-like regulatory EF-domain of NOX5 is partially unfolded and detached from the rest of the protein in the absence of calcium. In the presence of calcium, the C-terminal lobe of the EF-domain acquires an ordered and more compact structure that enables its binding to the enzyme dehydrogenase (DH) domain. Our spectroscopic and mutagenesis studies further identified a set of conserved aspartate residues in the DH domain that are essential for NOX5 activation. Altogether, our work shows that calcium induces an unfolded-to-folded transition of the EF-domain that promotes direct interaction with a conserved regulatory region, resulting in NOX5 activation
