We propose a framework in which interventions are described as situations affording the expression of certain personality traits to provide a systematic understanding of differential intervention response by personality traits. The goal of the present paper is twofold: 1) elaborate on the proposed framework, and 2) provide an initial test of this framework. We empirically tested this framework using data from a Randomized Controlled Trial (N = 176) that examined a smartphone-based intervention aimed at increasing future-oriented thinking and behavior, and assessed HEXACO personality traits.

The intensity of respiratory treatment in acute respiratory distress syndrome (ARDS) is traditionally adjusted based on oxygenation severity, as defined by the mild, moderate, and severe Berlin classifications. However, ventilator-induced lung injury (VILI) is primarily determined by ventilator settings, namely tidal volume, respiratory rate, and positive end-expiratory pressure (PEEP). All these variables, along with respiratory elastance, are included in the concept of mechanical power.

Zeolite Additives for Flexible Packaging Polymers: Current Status Review and Future Perspectives.

Polymers (Basel)

December 2024

ACLabs-Applied Chemistry Labs, Department of Chemical, Materials and Industrial Production Engineering, University of Naples Federico II, P.le Tecchio 80, 80125 Napoli, Italy.

Zeolites are interesting inorganic additives that could be employed for plastic packaging applications. Polyethylene (PE) and polypropylene (PP) are intensively used for packaging as they provide great performance at low cost, even though they have poor environmental sustainability and may be more valorized. Biodegradable polymers may therefore represent a more eco-friendly alternative, but still, they have limited applications due to their generally inferior properties.

Introduction: The recently published ACR/EULAR classification criteria score (3 points or more) both clinical and laboratory criteria to define the presence of antiphospholipid syndrome (APS). The clinical criteria have been better defined while laboratory criteria remain the same [lupus anticoagulant (LA), anticardiolipin (aCL) and anti ß2-Glycoprotein I (aß2GPI) antibodies] but with different impact (points) on the classification of patients. APS is excluded if more than 3 years separate positive test for antiphospholipid antibodies (aPL) and clinical manifestation.

Color crowding considered as adaptive spatial integration.

J Vis

December 2024

Department of Neurosciences, Psychology, Drug Research and Child Health, University of Florence, Firenze, Italy.

Crowding is the inability to recognize an object in clutter, classically considered a fundamental low-level bottleneck to object recognition. Recently, however, it has been suggested that crowding, like predictive phenomena such as serial dependence, may result from optimizing strategies that exploit redundancies in natural scenes. This notion leads to several testable predictions, such as crowding being greater for nonsalient targets and, counterintuitively, that flanker interference should be associated with higher precision in judgements, leading to a lower overall error rate.

Lactonase activity of α-carbonic anhydrases allows identification of novel inhibitors.

Arch Pharm (Weinheim)

January 2025

NEUROFARBA Department, Pharmaceutical and Nutraceutical Section, University of Florence, Firenze, Italy.

Lactones, a diverse and abundant class of molecules found in nature, exhibit a wide range of bioactivities, including anti-inflammatory, anticancer, and antibacterial effects. Among them, acyl homoserine lactones (AHSLs) play a crucial role in quorum sensing, influencing bacterial pathogenicity and biofilm formation in Gram-negative bacteria. Paraoxonases (PONs), calcium-containing enzymes known for their lactonase activity, have been shown to hydrolyze AHSLs and reduce the biofilm formation of several pathogenic bacteria.
