Novel antimalarial 3-substituted quinolones isosteres with improved pharmacokinetic properties.

Eur J Med Chem

December 2024

School of Pharmacy and Food Engineering, Wuyi University, 529020, Jiangmen, China; Department of Chemistry, University of Liverpool, L69 7ZD, Liverpool, UK. Electronic address:

Aryl quinolone derivatives can target the cytochrome bc complex of Plasmodium falciparum, exhibiting excellent in vitro and in vivo antimalarial activity. However, their clinical development has been hindered due to their poor aqueous solubility profiles. In this study, a series of bioisosteres containing saturated heterocycles fused to a 4-pyridone ring were designed to replace the inherently poorly soluble quinolone core in antimalarial quinolones with the aim to reduce π-π stacking interactions in the crystal packing solid state, and a synthetic route was developed to prepare these alternative core derivatives.

Background: It is crucial to distinguish type-1 myocardial infarction (T1MI) from type-2 myocardial infarction (T2MI) at admission and during hospitalization to avoid unnecessary invasive exams and inappropriate admissions to the acute cardiac care unit.

Objectives: The purpose of the study was to define a simple profile derived from commonly used biomarkers to differentiate T1MI from T2MI.

Methods: We prospectively enrolled in an observational study 213 iconsecutive patients with a provisional diagnosis of non-ST-elevation acute myocardial infarction (NSTEMI) admitted to the Cardiology Department.

Background: Artificial intelligence (AI) models are emerging as promising tools to identify predictive features among data coming from health records. Their application in clinical routine is still challenging, due to technical limits and to explainability issues in this specific setting. Response to standard first-line immunotherapy (ICI) in metastatic Non-Small-Cell Lung Cancer (NSCLC) is an interesting population for machine learning (ML), since up to 30% of patients do not benefit.

Article Synopsis
  • The study investigates the thermoelectric properties of Abrikosov vortices in type-II superconductors under quantum conditions, focusing on two setups: a superconductor-insulator-normal-metal junction and a scanning tunneling microscope tip over the superconductor.
  • The strong breaking of particle-hole symmetry in these vortices leads to a significant thermoelectric response, predicting thermovoltage values of a few mV/K at temperatures near absolute zero.
  • The study finds favorable thermoelectric coefficients, with a figure of merit (ZT) around 1 for the S-I-N junction and over 3 when using the STM junction, suggesting potential applications as low-temperature thermocouples or in detecting single low-energy photons.

Superdiffusion is surprisingly easily observed even in systems without the integrability underpinning this phenomenon. Indeed, the classical Heisenberg chain-one of the simplest many-body systems, and firmly believed to be nonintegrable-evinces a long-lived regime of anomalous, superdiffusive spin dynamics at finite temperature. Similarly, superdiffusion persists for long timescales, even at high temperature, for small perturbations around a related integrable model.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Institute of Physics, Ecole Polytechnique Fédérale de Lausanne (EPFL), Lausanne, Switzerland.

Article Synopsis
  • The study investigates CP symmetry violation in the decay of D^{+} particles into K^{-}K^{+}π^{+} using data from proton-proton collisions at a high energy of 13 TeV.
  • A unique model-independent method was employed to analyze the phase-space distributions of D^{+} and D^{-} particles, correcting for any instrumental biases using D_{s}^{+} decays.
  • The findings indicate no significant evidence of CP violation, with a p value of 8.1%, and measure specific CP asymmetry observables, marking this study as the most sensitive search of its kind in multibody decays.

Self-Interacting Dark Sectors in Supernovae Can Behave as a Relativistic Fluid.

Phys Rev Lett

December 2024

Dipartimento di Fisica e Astronomia, Università degli Studi di Padova, Via Marzolo 8, 35131 Padova, Italy.

We revisit supernova (SN) bounds on a hidden sector consisting of millicharged particles χ and a massless dark photon. Unless the self-coupling is fine-tuned to be small, rather than exiting the SN core as a gas, the particles form a relativistic fluid and subsequent dark QED fireball, streaming out against the drag due to the interaction with matter. Novel bounds due to excessive energy deposition in the mantle of low-energy supernovae can be obtained.

Resonant Conversion of Wave Dark Matter in the Ionosphere.

Phys Rev Lett

December 2024

Departement de Physique Theorique, Universite de Geneve, 24 quai Ernest Ansermet, 1211 Geneve 4, Switzerland.

Article Synopsis
  • Researchers are investigating how resonant dark matter can convert into low-frequency radio waves in Earth's ionosphere, particularly in the mass range of about 10^{-9} to 10^{-8} eV.
  • The typical methods for calculating this conversion are inadequate due to the nonrelativistic nature of dark matter, so a new approach involving a second-order boundary-value problem is applied.
  • Using a small dipole antenna to detect these radio waves could increase sensitivity to dark photon and axionlike particle dark matter, offering a new avenue for exploring uncharted regions of dark matter physics.

The great advances in diagnostic and therapeutic skills of most sectors of medicine and dentistry have led to an increasingly greater demand from patients for accuracy, attention and diligence by healthcare workers. Dentistry is one of the branches most frequently involved in claims for damages from malpractice, especially in those sectors that are particularly costly and of significant aesthetic value. Aim of the study was to compare data of malpractice claims with those of other Authors to identify similarities and/or differences in the results and to increase epidemiological knowledge in the area of dental malpractice.

The feasibility of the adult age estimation 3D-CBCT method on ancient human remains.

J Forensic Odontostomatol

December 2024

Laboratory of Personal Identification and Forensic Morphology, Department of Health Sciences, University of Florence, Florence, Italy.

The age estimation of skeletal remains still represents a central issue not only for the reconstruction of the so-called "biological profile," but mostly for the palaeodemographic investigation. This research aims at verifying the feasibility of the adult age estimation method developed on living people by Pinchi et al. (2015 and 2018), for estimating the age at the death of 37 subjects from ancient populations found in two different Italian necropolis of archaeological interest (Mont'e Prama and Florence, X-IX century B.

Effects of long-term steroid therapy on the results of dental age estimation using pulp/tooth ratio.

J Forensic Odontostomatol

December 2024

Department of Medicine and Health Science "Vincenzo Tiberio", University of Molise, AgeEstimation Project, Campobasso, Italy.

Article Synopsis
  • Forensic age estimation via dental radiographs can be inaccurate, particularly in long-term steroid users who show abnormal pulp chamber constrictions.
  • A study assessed eight steroid users in their 30s to 40s, measuring pulp and tooth areas to estimate age through canine radiographs, revealing significant discrepancies between estimated and actual ages.
  • The mean error was about 19-23 years, indicating that unusual pulp chamber findings could help infer a patient's medical history in forensic evaluations.

Department of Biochemistry Cell and Systems Biology, Institute of Systems, Molecular and Integrative Biology, University of Liverpool, Liverpool, UK.

Lysosomal pH dysregulation is a critical element of the pathophysiology of neurodegenerative diseases, cancers, and lysosomal storage disorders (LSDs). To study the role of lysosomes in pathophysiology, probes to analyze lysosomal size, positioning, and pH are indispensable tools. Here, we developed and characterized a ratiometric genetically encoded lysosomal pH probe, RpH-ILV, targeted to a subpopulation of lysosomal intraluminal vesicles.
