Weight-Based Discrimination in the Italian Labor Market: an Analysis of the Interaction with Gender and Ethnicity

Access to the Italian job market is undermined by several kinds of discrimination influencing the opportunities for individuals to obtain a job. In this study, we analyze together the impact of three of the most relevant kinds of discrimination operating in the Italian labor market: gender, race, and weight. Our aim is to assess whether gender and race either increase or decrease the impact of weight-based discrimination. In this respect, we submit a set of fictitious r\ue9sum\ue9s including photos of either obese or thin applicants in response to real online job offers. Our results indicate that the strongest kind of discrimination operating in the Italian labor market is the one connected to the candidate\u2019s geographical origin. Moreover, we find discrimination based on body weight to be more relevant within immigrants than within natives, and gender gap appears to be higher within the obese candidates\u2019 group compared to the normal-weight candidates\u2019 one. This last result is particularly relevant, as the growing rates of obesity forecasted for the next years could in turn produce an increase in the gender gap, which in Italy is already massive

Immigrants and Italian labor market: statistical or taste-based discrimination?

Types of discrimination are usually distinguished by economic theory in statistical and taste-based. Using a correspondence experiment, we analyze which of the two affects Italian labor market the most. In this respect, we studied the difference in discrimination reserved to first- and second-generation immigrants, taking gender differences into account. Even if we want to admit a rational discrimination based on perceived productivity differences (statistical discrimination) against first-generation immigrants (concerning language and education gaps), the same would not be reasonable for second-generation ones. Since they are born and educated in Italy, where they have always lived, the associated discrimination must be taste-based

The willingness to pay of Sicilian consumers for a wine obtained with sustainable production method: An estimate through an ordered probit sample-selection model

The growing presence of Sicilian sustainable wine has pushed the research group to investigate and analyse the consumers' behaviour and their potential willingness to pay a premium price for the wine obtained through sustainable production processes. The analysis of the consumer's behaviour towards the wine made with sustainable production methods is carried out in order to provide potentially useful indications to Italian and in particular Sicilian wine enterprises regarding the production and marketing strategies to undertake in a future perspective. This study shows the result of an empirical investigation on the consumption of sustainable wine in Sicily. Through the Ordered (demographic profile, preference and attitudes), which influence the consumers' choices regarding sustainable wine. The assessment, based on the submission of a questionnaire, has highlighted the willingness to pay a premium price on the part of the 546 consumers interviewed. The study points out that the knowledge of sustainable production methods significantly influences the decision to support a premium price for wine consumption. This attests to the fact that a more attentive and informed consumer is ready to pay more for products obtained according to the principles of environmental sustainability

Single-molecule detection of α-Synuclein oligomers in Parkinson's disease patients using nanopores

α-Synuclein (α-Syn) is an intrinsically disordered protein whose aggregation in the brain has been significantly implicated in Parkinson's disease (PD). Beyond the brain, oligomers of α-Synuclein are also found in cerebrospinal fluid (CSF) and blood, where the analysis of these aggregates may provide diagnostic routes and enable a better understanding of disease mechanisms. However, detecting α-Syn in CSF and blood is challenging due to its heterogeneous protein size and shape, and low abundance in clinical samples. Nanopore technology offers a promising route for the detection of single proteins in solution; however, the method often lacks the necessary selectivity in complex biofluids, where multiple background biomolecules are present. We address these limitations by developing a strategy that combines nanopore-based sensing with molecular carriers that can specifically capture α-Syn oligomers with sizes of less than 20 nm. We demonstrate that α-Synuclein oligomers can be detected directly in clinical samples, with minimal sample processing, by their ion current characteristics and successfully utilize this technology to differentiate cohorts of PD patients from healthy controls. The measurements indicate that detecting α-Syn oligomers present in CSF may potentially provide valuable insights into the progression and monitoring of Parkinson's disease

To be or not to be a germ cell: The extragonadal germ cell tumor paradigm

In the human embryo, the genetic program that orchestrates germ cell specification in-volves the activation of epigenetic and transcriptional mechanisms that make the germline a unique cell population continuously poised between germness and pluripotency. Germ cell tumors, neo-plasias originating from fetal or neonatal germ cells, maintain such dichotomy and can adopt either pluripotent features (embryonal carcinomas) or germness features (seminomas) with a wide range of phenotypes in between these histotypes. Here, we review the basic concepts of cell specification, migration and gonadal colonization of human primordial germ cells (hPGCs) highlighting the analogies of transcriptional/epigenetic programs between these two cell types

Biotinylated polyaminoacid-based nanoparticles for the targeted delivery of lenvatinib towards hepatocarcinoma

In this work, we describe the development of targeted polymeric nanoparticles loaded with lenvatinib for the treatment of hepatocellular carcinoma (HCC). A synthetic brush copolymer (PHEA-g-BIB-pButMA-g-PEG-biotin) was synthesized from α-poly(N-2-hydroxyethyl)-D,L-aspartamide (PHEA) by a three-step reaction involving atom transfer radical polymerisation (ATRP) to graft hydrophobic polybutylmethacrylate pendant groups and further conjugation with biotinylated polyethylene glycol via carbonate ester. Subsequently, lenvatinib-loaded nanoparticles were obtained and characterized demonstrating colloidal size, negative zeta potential, biotin exposure on the surface and the ability to release lenvatinib in a sustained manner. Lenvatinib-loaded nanoparticles were tested in vitro on HCC cells to evaluate their anticancer efficacy compared to free drug. Furthermore, the enhanced in vivo efficacy of lenvatinib-loaded nanoparticles on nude mice HCC xenograft models was demonstrated by evaluating tumor burdens, apoptotic markers and histological scores after administration of lenvatinib-nanoparticles via intraperitoneal or oral route. Finally, in vivo biodistribution studies were performed, demonstrating the ability of the prepared drug delivery systems to significantly accumulate in the solid tumor by active targeting, due to the presence of biotin on the nanoparticle surface

Remote-working and home-learning: how the Italian academic population dealt with changes due to the COVID-19 pandemic lockdown

The COVID-19 pandemic introduced changes in people’s lives that affected their mental health. Our study aimed to explore the level of psychological distress in the academic population dur- ing the lockdown period and investigate its association with the new working or studying conditions. The study sample included 9364 students and 2159 employees from five Italian universities from the study IO CONTO 2020. We applied linear regression models to investigate the association between home learning or remote working conditions and psychological distress, separately for students and employees. Psychological distress was assessed using the Hospital Anxiety and Depression Scale (HADS). In both students and employees, higher levels of distress were significantly associated with study/work–family conflicts, concerns about their future careers, and inadequacy of equipment; in employees, higher levels of distress were significantly associated with a lack of clarity on work objectives. Our results are in line with previous research on the impact of spaces and equipment in remote working/studying from home. Moreover, the study contributes to deepening the association between well-being and telework–family conflict, which in the literature is still equivocal. Practical implications require academic governance to promote sustainable environments both in remote and hybrid work conditions, by referring to a specific management by objectives approach

Targeting the NO-cGMP-PDE5 pathway in COVID-19 infection

A pandemic outbreak of COVID-19 has been sweeping the world since December. It begins as a respiratory infection that, mainly in men with diabetes or renal impairment, evolves into a systemic disease, with SARDS, progressive endothelial cell damage, abnormal clotting and impaired cardiovascular and liver function. Some clinical trials are testing biological drugs to limit the immune system dysregulation, "cytokines storm", that causes the systemic complications of COVID-19. The contraindications of these drugs and their cost raise concerns over the implications of their widespread availability. Numerous clinical and experimental studies have revealed a role for the nitric oxide (NO)-cyclic GMP-phosphodiesterase type 5 (PDE5) pathway in modulating low-grade inflammation in patients with metabolic diseases, offering cardiovascular protection. PDE5 inhibition favors an anti-inflammatory response by modulating activated T cells, reducing cytokine release, lowering fibrosis, increasing oxygen diffusion, stimulating vascular repair. PDE5 is highly expressed in the lungs, where its inhibition improves pulmonary fibrosis, a complication of severe COVID-19 disease. We performed a systematic review of all evidence documenting any involvement of the NO-cGMP-PDE5 axis in the pathophysiology of COVID-19, presenting the ongoing clinical trials aimed at modulating this axis, including our own "silDEnafil administration in DiAbetic and dysmetaboLic patients with COVID-19 (DEDALO trial)". The reviewed evidence suggests that PDE5 inhibitors could offer a new strategy in managing COVID-19 by (i) counteracting the Ang-II-mediated downregulation of AT-1 receptor; (ii) acting on monocyte switching, thus reducing pro-inflammatory cytokines, interstitial infiltration and the vessel damage responsible for alveolar hemorrhage-necrosis; (iii) inhibiting the transition of endothelial and smooth muscle cells to mesenchymal cells in the pulmonary artery, preventing clotting and thrombotic complications. If the ongoing trials presented herein should provide positive findings, the low cost, wide availability and temperature stability of PDE5 inhibitors could make them a major resource to combat COVID-19 in developing countries
