Mechanism of oxygen reduction chemical affinity in NiO/SiO interfaces irradiated with keV energy hydrogen and helium ions for heterostructure fabrication.

Low-energy light ion beams are an essential resource in lithography for nanopatterning magnetic materials and interfaces due to their ability to modify the structure and properties of metamaterials. Here we create ferromagnetic/non-ferromagnetic heterostructures with a controlled layer thickness and nanometer-scale precision. For this, hydrogen ion (H) irradiation is used to reduce the antiferromagnetic nickel oxide (NiO) layer into ferromagnetic Ni with lower fluence than in the case of helium ion (He) irradiation.

The D-lactate enigma: exploring the inflammatory influence of D-lactate in cattle.

D-lactic acidosis is associated with fermentative disturbances and is often marked by elevated levels of D-lactic acid in the blood, ruminal fluid, and synovial fluid in cattle. D-lactic acidosis is linked to various inflammatory manifestations, and although the causative factors have been extensively explored, the exact pathogenesis of the associated inflammation remains elusive. Notably, less attention has been given to D-lactate, a stereoisomer found in the plasma of affected animals, which may lead to D-lactic acidosis.

Immune-inflammatory effects of the multicomponent intervention FIBROWALK in outdoor and online formats for patients with fibromyalgia.

The multicomponent intervention FIBROWALK integrates pain science education (PSE), therapeutic exercise, cognitive behavioral therapy (CBT), and mindfulness training for treating fibromyalgia (FM). This study investigated the effects of the FIBROWALK in online (FIBRO-On) and outdoor (FIBRO-Out) formats compared to treatment-as-usual (TAU) on core clinical variables along with serum immune-inflammatory biomarkers and brain-derived neurotrophic factor (BDNF). Furthermore, the predictive value of these biomarkers on clinical response to FIBROWALK was also evaluated.

A novel magnetic-assisted ionic liquid-based microextraction method (MA-ILBME): Specific design system for sensitive spectrophotometric analysis of paracetamol as a pharmaceutical pollutant in environmental samples.

Monitoring paracetamol levels in environmental samples is essential, as this widely used pharmaceutical can degrade water quality and adversely affect both ecosystems and human health. To address this issue, a novel, simple, sensitive, and accurate method has been developed. This method employs a functionalized ionic liquid, 2-(4-hydroxybenzyl)hydrazinium chloride ([HBH][Cl]), specifically designed to structurally mimic paracetamol and function as a complexing agent.

Per- and polyfluoroalkylated substances (PFAS) in the feathers and excreta of Gentoo penguins (Pygoscelis papua) from the Antarctic Peninsula.

Per- and polyfluoroalkyl substances (PFAS) exhibit widespread global distribution, extending to remote regions including Antarctica. Despite potential adverse effects on seabirds, PFAS exposure among Antarctic penguins remains poorly studied. We investigated the occurrence of 29 PFAS compounds in feathers and excreta of Gentoo penguins (Pygoscelis papua) from Fildes Bay, Antarctica.

Trained innate immunity as a potential link between preeclampsia and future cardiovascular disease.

Preeclampsia (PE) is a complex pregnancy syndrome characterized by hypertension with or without proteinuria, affecting 2-6% of pregnancies globally. PE is characterized by excessive release of damage-associated molecular patterns (DAMPs) into the maternal circulation. This DAMP-rich milieu acts on innate immune cells, inducing a proinflammatory state characterized by elevated cytokines such as IL-1β and IL-18.

The nasal mycobiome of individuals with allergic rhinitis and asthma differs from that of healthy controls in composition, structure and function.

Allergic rhinitis (AR) and asthma (AS) are two of the most common chronic respiratory diseases and a major public health concern. Multiple studies have demonstrated the role of the nasal bacteriome in AR and AS, but little is known about the airway mycobiome and its potential association to airway inflammatory diseases. Here we used the internal transcriber spacers (ITS) 1 and 2 and high-throughput sequencing to characterize the nasal mycobiome of 339 individuals with AR, AR with asthma (ARAS), AS and healthy controls (CT).

Uncharted territory: the arrival of (Zetterstedt, 1850) (Diptera: Psychodidae) in Maritime Antarctica.

Despite increasing awareness of the threats they pose, exotic species continue to arrive in Antarctica with anthropogenic assistance, some of which inevitably have the potential to become aggressively invasive. Here, we provide the first report of the globally cosmopolitan species (Diptera, Psychodidae; commonly known as moth flies) in Antarctica during the austral summer of 2021/2022, with the identification confirmed using traditional taxonomic and molecular approaches. The species was present in very large numbers and, although predominantly associated with the drainage and wastewater systems of Antarctic national operator stations in synanthropic situations, it was also present in surrounding natural habitats.

The Implementation of the Biopsychosocial Model: Individuals With Alcohol Use Disorder and Post-Traumatic Stress Disorder.

Introduction: This extensive literature review investigates the relationship between post-traumatic stress disorder (PTSD) and alcohol use disorder (AUD), focusing on the neurobiological changes associated with their co-occurrence. Given that these disorders frequently coexist, we analyze mechanisms through which alcohol serves as a coping strategy for PTSD symptoms, particularly highlighting the drinking-to-cope self-medication model, which suggests that alcohol use exacerbates PTSD symptoms and complicates recovery.

Methods: A systematic literature search was conducted across multiple databases, including PubMed and Google Scholar, to identify studies examining the intersection of the biopsychosocial model with PTSD, AUD, and associated neural alterations.

Comparative Effects of the Free Weights and Smith Machine Squat and Bench Press: The Important Role of Specificity for Strength Adaptations.

Purpose: Although previous studies have compared strength-training adaptations between free weights (FW) and machine-guided exercises, those studies did not use a Smith machine (SM), which most closely replicates the exercises performed with FW. Thus, the aim of the present study was to investigate the chronic effects of strength-focused, velocity-based training regimens using FW versus SM.

Methods: Thirty-seven sport-science students (14 female) were assigned, balanced by sex and relative strength, to either an FW or SM training group.
