Drug-Drug Interactions Between DAAs and Anticoagulants or Antiplatelets: A Position Paper of the Italian Anticoagulation Clinics.

The natural history of chronic hepatitis C virus (HCV) infection has changed after the introduction of direct-acting antiviral agents (DAAs). Screening programs have been ongoing to reach the World Health Organisation's goal of HCV elimination by 2030, and most infected people are eligible for treatment. Given the increased cardiovascular risk in people with HCV infection and the metabolic pathways of DAAs, it is not uncommon to face the issue of drug-drug interactions (DDIs) with antiplatelet or anticoagulant drugs.

Revisiting the Rytov approximation in diffuse optics and its applications for the inverse and forward problems.

We propose an overview of the Rytov approximation in diffuse optics of biological tissues, for the inverse and forward problems. First, we show a physical interpretation of the Rytov approximation as a type of partial pathlength (named fluence rate partial pathlength) which is distinct from the usual partial pathlength for reflectance measurements. Second, we study the accuracy of the Rytov approximation for the calculation of Jacobians considering absorption perturbations and reflectance measurements.

Physical Activity and Sedentary Behavior on Well-Being and Self-Rated Health of Italian Public Health Medical Residents During the COVID-19 Pandemic: The PHRASI Study.

High workloads and extended work shift greatly limit the opportunities for medical residents to adopt a healthy lifestyle by practicing regular physical exercise.

Discrete Synaptic Events Induce Global Oscillations in Balanced Neural Networks.

Despite the fact that neural dynamics is triggered by discrete synaptic events, the neural response is usually obtained within the diffusion approximation representing the synaptic inputs as Gaussian noise. We derive a mean-field formalism encompassing synaptic shot noise for sparse balanced neural networks. For low (high) excitatory drive (inhibitory feedback) global oscillations emerge via continuous or hysteretic transitions, correctly predicted by our approach, but not from the diffusion approximation.

Human carbonic anhydrases (hCAs) are widespread zinc enzymes that catalyze the hydration of CO to bicarbonate and a proton. Currently, 15 isoforms have been identified, of which only 12 are catalytically active. Given their involvement in numerous physiological and pathological processes, hCAs are recognized therapeutic targets for the development of inhibitors with biomedical applications.

Synergistic Combination of Cross-Linked Polymer and Concentrated Ionic Liquid for Electrolytes with High Stability in Solid-State Lithium Metal Batteries.

Poly(ethylene oxide)-(PEO-based solid polymer electrolytes (SPEs) are regarded as excellent candidates for solid-state lithium metal batteries (SSLMBs) due to their inherent safety advantages, processability, low cost, and excellent Li+ ion solvation. However, they suffer from limited oxidation stability (up to 4 V vs Li/Li). In this study, a crosslinked polymer-in-concentrated ionic liquid (PCIL) SPE consisting of PEO, -propyl--methylpyrrolidinium bis(fluorosulfonyl)imide (CmpyrFSI) ionic liquid (IL), and lithium bis(fluorosulfonyl)imide (LiFSI) salt is developed.

Structural Commonalities Determined by Physicochemical Principles in the Complex Polymorphism of the Amyloid State of Proteins.

Advances in solid-state nuclear magnetic resonance (ssNMR) spectroscopy and cryogenic electron microscopy (cryoEM) have revealed the polymorphic nature of the amyloid state of proteins. Given the association of amyloid with protein misfolding disorders, it is important to understand the principles underlying this polymorphism. To address this problem, we combined computational tools to predict the specific regions of the sequence forming the β-spine of amyloid fibrils with the availability of 30, 83 and 24 amyloid structures deposited in the Protein Data Bank (PDB) and Amyloid Atlas (AA) for the amyloid β (Aβ) peptide, α-synuclein (αS), and the 4R isoforms of tau, associated with Alzheimer's disease, Parkinson's disease, and various tauopathies, respectively.

Energy cascade and Burgers turbulence in the Fermi-Pasta-Ulam-Tsingou chain.

The dynamics of initial long-wavelength excitations of the Fermi-Pasta-Ulam-Tsingou chain has been the subject of intense investigations since the pioneering work of Fermi and collaborators. We have recently found a regime where the spectrum of the Fourier modes decays with a power law and we have interpreted this regime as a transient turbulence associated with the Burgers equation. In this paper we present the full derivation of the latter equation from the lattice dynamics using an infinite-dimensional Hamiltonian perturbation theory.

Combined effects of fluoroquinolone antibiotic enrofloxacin and rising sea temperatures on the health of the Mediterranean mussel (Mytilus galloprovincialis): Exploring physiological, biochemical, and energetic balance dynamics.

Human activity exposes organisms in marine ecosystems to numerous stressors, including rising seawater temperatures and antibiotic contamination. The present study investigated the impacts of environmentally relevant concentrations of the fluoroquinolone (FQ) antibiotic enrofloxacin (ENR), specifically 5 and 500 ng/L, in Mytilus galloprovincialis under ambient (20 °C) and predicted warming (25 °C) conditions after 14 days of exposure, followed by a 14-day recovery period in the absence of ENR. The chemical analyses revealed significant variability in bioaccumulation in mussel tissues.
