Atom's Dynamics and Crystal Structure: An Ordinal Pattern Method.

J Phys Chem A

January 2025

Institute of Materials Engineering, University of Silesia in Katowice, 75 Pułku Piechoty 1A, 41-500 Chorzów, Poland.

The ubiquitous nature of thermal fluctuations poses a limitation on the identification of crystal structures. However, the trajectory of an atom carries a fingerprint of its surroundings. This rationalizes the search for a method that can determine the local atomic configuration via the analysis of the movement of an individual atom.

This work is focused on the impact of temperature and deformation on the mechanical properties, specifically the elastic modulus () of the amorphous regions in semicrystalline polymers, using polypropylene as a case study. It has been shown that increasing temperature results in an decrease due to the enhanced mobility of polymer chains, triggered by the activation of α relaxation processes within the crystalline component. Consequently, rising temperature reduces the "stiffening" effect of the crystalline regions on the interlamellar layers.

Histamine H receptor blockade alleviates neuropathic pain through the regulation of glial cells activation.

Biomed Pharmacother

January 2025

Maj Institute of Pharmacology, Polish Academy of Sciences, Department of Neurochemistry, 12 Smetna Str., Krakow 31-343, Poland. Electronic address:

Neuropathic pain is a disorder affecting the somatosensory nervous system. However, this condition is also characterized by significant neuroinflammation, primarily involving CNS-resident non-neuronal cells. A promising target for developing new analgesics is histamine H receptor (HR); thus, we aimed to determine the influence of a novel HR antagonist/inverse agonist, E-98 (1-(7-(4-chlorophenoxy)heptyl)-3-methylpiperidine), on pain symptoms and glia activation in model of neuropathic pain in male mice (chronic constriction injury to the sciatic nerve).

Introduction: Despite research supporting menopause hormonal therapy for menopausal women, its use continues to decline in most European countries and the United States. Experts highlighted the need for global assessment tools to assist clinicians in evaluating treatment for symptomatic menopausal women, which led to the development of the Menopause Treatment Tool, with separate versions for women and healthcare professionals. Both versions of the tool focus on menopausal symptoms, risk levels and suggested actions; the women's tool is administered prior to the consultation, while the clinician tool is administered by the clinician during the clinical consultation.

Ultrasound shear wave elastography (SWE) is widely used in clinical applications for non-invasive measurements of soft tissue viscoelasticity. The study of tissue viscoelasticity often involves the analysis of shear wave phase velocity dispersion curves, which show how the phase velocity varies with frequency or wavelength. In this study, we propose an alternative method to the two-dimensional Fourier transform (2D-FT) and Phase Gradient (PG) methods for shear wave phase velocity estimation.

In three studies (total N = 622), the effects of threat to control on subsequent moral judgement were examined. After recalling a lack-of-control experience, participants evaluated the morality of a protagonist's decisions in a series of incongruent moral dilemmas. We found that a control-threatening reminder made moral judgements more utilitarian on the deontological-utilitarian dimension, which is consistent with the control motivation theory.

Background: Electrographic flow (EGF) mapping allows for the visualization of global atrial wavefront propagations. One mechanism of initiation and maintenance of atrial fibrillation (AF) is stimulation from EGF-identified focal sources that serve as driver sites of fibrillatory conduction. Electrographic flow consistency (EGFC) further quantifies the concordance of observed wavefront patterns, indicating that a healthier substrate shows more organized wavefront propagation and higher EGFC.

Research on titanium nanotubes modified with metal sulfides, particularly bismuth sulfide (BiS), aims to create heterostructures that efficiently absorb sunlight and then separate photogenerated charge carriers, thereby enhancing the energy conversion efficiency. This study shows a key role of solvent used for sulfide and bismuth salt solutions used during successive ionic layer adsorption and reaction (SILAR) onto the morphology, structure, and photoresponse of the heterojunction where one element is represented by semitransparent titania nanotubes (gTiNT) and the second is BiS. Using 2-methoxyethanol and methanol during SILAR, results in remarkably photoactive 3D heterostructure and recorded photocurrents were 44 times higher compared to bare titania nanotubes.

The dorsolateral prefrontal cortex (dlPFC) is increasingly targeted by various noninvasive transcranial magnetic stimulation or transcranial current stimulation protocols in a range of neuropsychiatric and other brain disorders. The rationale for this therapeutic modulation remains elusive. A model is proposed, and up-to-date evidence is discussed, suggesting that the dlPFC is a high-level cortical centre where uncertainty management, movement facilitation, and cardiovascular control processes are intertwined and integrated to deliver optimal behavioural responses in particular environmental or emotional contexts.

Department of Biodiversity Studies and Bioeducation, University of Lodz, Faculty of Biology and Environmental Protection, Banacha 1/3, Lodz 90-237, Poland.

There is a growing body of evidence that urbanization can affect body condition and immune function in wild birds, although these effects may be complex and taxa-specific. Here, we assessed the effects of urbanization on body condition (size-corrected body mass and haemoglobin concentration) and innate immune defences (haemolysis-haemagglutination assay, haptoglobin concentration and bacterial killing assay) in 136 Eurasian coots () from three urban and three non-urban populations across Poland. We also quantified the heterophil to lymphocyte ratio to control for the potential effect of physiological stress on immune defences.
