Magneto-ionic vortices: voltage-reconfigurable swirling-spin analog-memory nanomagnets.

Rapid progress in information technologies has spurred the need for innovative memory concepts, for which advanced data-processing methods and tailor-made materials are required. Here we introduce a previously unexplored nanoscale magnetic object: an analog magnetic vortex controlled by electric-field-induced ion motion, termed magneto-ionic vortex or "vortion". This state arises from paramagnetic FeCoN through voltage gating and gradual N ion extraction within patterned nanodots.

Large-scale energy decomposition for the analysis of protein stability.

To carry out their functions in cells, proteins are required to fold into well-defined three-dimensional conformations. The stability of the folded state dictates several aspects of protein life, such as their evolution, interactions, and selection of structures that are ultimately linked to activity. Sequence mutations may change the stability profile and consequently impact structure and function.

Membrane-targeted push-pull azobenzenes for the optical modulation of membrane potential.

We introduce a family of membrane-targeted azobenzenes (MTs) with a push-pull character as a new tool for cell stimulation. These molecules are water soluble and spontaneously partition in the cell membrane. Upon light irradiation, they isomerize from trans to cis, changing the local charge distribution and thus stimulating the cell response.

Frailty, comorbidity, and multimorbidity and their relation with medications adherence in primary care older adults.

Purpose: To assess and compare, through a retrospective cohort study, the relationships between frailty, comorbidity, multimorbidity, and levels of adherence to lipid-lowering drugs (LLDs), antihypertensives and antidepressants.

Methods: In a primary care database, we selected a cohort of patients aged 60 or older on December 31, 2022. The date of the first prescription of the aforementioned medications was the study index date.

Treatment Algorithms for Continuous Low-Level Heat Wrap Therapy for the Management of Musculoskeletal Pain: An Italian Position Paper.

Musculoskeletal pain (MSP), which impacts bones, muscles, tendons, and ligaments, is a substantial worldwide pain disorder, characterized by muscle soreness, fatigue, inflammation, muscle spasms, sleep disruptions, and functional limitations. MSP is predominantly managed within the primary care setting. Recent consensus recognizes that heat therapy (HT) may provide potential benefits, especially in treating chronic MSP.

A Review of Current Approaches to Pain Management in Knee Osteoarthritis with a Focus on Italian Clinical Landscape.

The global cases of knee osteoarthritis (KOA) are projected to increase by 74.9% by 2050. Currently, over half of patients remain dissatisfied with their pain relief.

Implementation of a pilot checklist for control standardization on fishery goods consignments at the Livorno border control post.

To standardize control activities, it is necessary to introduce checklists to support the control of consignments entering the European Union through border control posts (BCPs). This study aimed to develop a pilot checklist for the control of fishery consignments, preliminarily identified as the predominant group of goods entering the Livorno (Italy) BCP. The design of the pilot checklist was preceded by i) a revision of the current European and national legislation on the general and specific objectives of border control activities on fishery products and ii) a comparative analysis of two checklists (one of the Ministry of Health and one of the former Livorno border inspection post) developed on the basis of the repealed legislation.

Structures, dynamics, complexes, and functions: From classic computation to artificial intelligence.

Computational approaches can provide highly detailed insight into the molecular recognition processes that underlie drug binding, the assembly of protein complexes, and the regulation of biological functional processes. Classical simulation methods can bridge a wide range of length- and time-scales typically involved in such processes. Lately, automated learning and artificial intelligence methods have shown the potential to expand the reach of physics-based approaches, ushering in the possibility to model and even design complex protein architectures.

Nanoactuator for Neuronal Optoporation.

Light-driven modulation of neuronal activity at high spatial-temporal resolution is becoming of high interest in neuroscience. In addition to optogenetics, nongenetic membrane-targeted nanomachines that alter the electrical state of the neuronal membranes are in demand. Here, we engineered and characterized a photoswitchable conjugated compound (BV-1) that spontaneously partitions into the neuronal membrane and undergoes a charge transfer upon light stimulation.

Molecular mechanisms of chaperone-directed protein folding: Insights from atomistic simulations.

Molecular chaperones, a family of proteins of which Hsp90 and Hsp70 are integral members, form an essential machinery to maintain healthy proteomes by controlling the folding and activation of a plethora of substrate client proteins. This is achieved through cycles in which Hsp90 and Hsp70, regulated by task-specific co-chaperones, process ATP and become part of a complex network that undergoes extensive compositional and conformational variations. Despite impressive advances in structural knowledge, the mechanisms that regulate the dynamics of functional assemblies, their response to nucleotides, and their relevance for client remodeling are still elusive.

A membrane intercalating metal-free conjugated organic photosensitizer for bacterial photodynamic inactivation.

Photodynamic inhibition (PDI) of bacteria represents a powerful strategy for dealing with multidrug-resistant pathogens and infections, as it exhibits minimal development of antibiotic resistance. The PDI action stems from the generation of a triplet state in the photosensitizer (PS), which subsequently transfers energy or electrons to molecular oxygen, resulting in the formation of reactive oxygen species (ROS). These ROS are then able to damage cells, eventually causing bacterial eradication.

Investigating Functional Impairment in Chronic Low Back Pain: A Qualitative Study from the Patients and Specialists' Perspectives.

Prompt and appropriate treatment of chronic low back pain (cLBP) is of the utmost importance for preventing relevant disability, high burden of disease, and increasing costs for the healthcare system. Recently, the concept of functional impairment has been associated with any type of chronic pain, and mounting attention has been paid to extending the aims of treatment beyond mere pain remission, including restoration of working capacity, everyday functioning, mobility, and quality of life. Nevertheless, a shared definition of functionality is still lacking.

Membrane Order Effect on the Photoresponse of an Organic Transducer.

Non-genetic photostimulation, which allows for control over cellular activity via the use of cell-targeting phototransducers, is widely used nowadays to study and modulate/restore biological functions. This approach relies on non-covalent interactions between the phototransducer and the cell membrane, thus implying that cell conditions and membrane status can dictate the effectiveness of the method. For instance, although immortalized cell lines are traditionally used in photostimulation experiments, it has been demonstrated that the number of passages they undergo is correlated to the worsening of cell conditions.

To clarify the safety profile of paracetamol for home-care patients with COVID-19: a real-world cohort study, with nested case-control analysis, in primary care.

Background And Objective: This study aimed to compare the prescribing patterns of paracetamol in COVID-19 with those for similar respiratory conditions and investigated the association between paracetamol use and COVID-19-related hospitalization/death.

Methods: Using a primary care data source, we conducted a cohort study to calculate the incidence rate of paracetamol use in COVID-19 and for similar respiratory conditions in 2020 and 2019 (i.e.

Changing the paradigm in postherpetic neuralgia treatment: lidocaine 700 mg medicated plaster.

Objective: Chronic pain is currently considered a disease state with biopsychosocial consequences and a negative impact on patients' quality of life (QoL). Pain from postherpetic neuralgia (PHN) can persist for months or years and is a prototypical example of chronic pain. We analyzed PHN as a model of chronic pain, including its effects on QoL and clinical aspects.

Azobenzene photoisomerization probes cell membrane viscosity.

The viscosity of cell membranes is a crucial parameter that affects the diffusion of small molecules both across and within the lipid membrane and that is related to several diseases. Therefore, the possibility to measure quantitatively membrane viscosity on the nanoscale is of great interest. Here, we report a complete investigation of the photophysics of an amphiphilic membrane-targeted azobenzene (ZIAPIN2) and we propose its use as a viscosity probe for cell membranes.

A Delphi Consensus Approach for the Management of Chronic Pain during and after the COVID-19 Era.

Due to a lack of published evidence on the topic, a modified Delphi approach was used to develop recommendations useful for chronic pain management during and after the COVID-19 pandemic. Focusing on the available literature and personal clinical expertise, an Italian board of nine professionals from different disciplines identified four main topics: prevention of chronic pain, treatment of chronic pain, consequences of inadequate treatment, and perspectives. They elaborated a semi-structured questionnaire.

COVID-19 and aortic disease: a practical systematic review of the literature on management and outcomes.

Introduction: Since the outbreak of the 2019 coronavirus (COVID-19), vascular specialists have faced dramatic changes in clinical and surgical practice. Although COVID-19 pulmonary signs and symptoms were the most pertinent problems initially, in the long term, cardiovascular complications became the most fearsome, with poor outcomes in terms of morbidity and mortality. Algorithms and decision-making procedures have been modified, not only to treat new clinical findings in COVID-19 positive patients, but also to avoid complications related to pulmonary and systemic infections.
