Strategic risk factor selection in disease risk mapping applied to the African swine fever outbreak in Sweden.

Risk mapping in epidemiology is a strategic tool that identifies high-risk areas for disease outbreaks, guiding preventive, surveillance, and control measures. In this study, we investigated how the selection of risk factors in ASF risk mapping affected the output of risk maps using the outbreak in Fagersta, Sweden as a study area. We identified ASFV risk factors by considering the sequence of introduction, release, and spread.

Association Between Childhood Trauma and Anhedonia-Related Symptoms: The Mediation Role of Trait Anhedonia and Circulating Proteins.

Background: Though accumulating evidence suggests an association between childhood trauma and anhedonia, further analysis is needed to consider specific traumatic dimensions, both traits and state anhedonia, and the role of circulating proteins. Therefore, this study investigated the association between different types of childhood traumas and their influence on anhedonia-related symptoms, and to evaluate the influence of anhedonia traits and plasma proteins as mediators.

Methods: This study included 170 patients with schizophrenia, bipolar disorder, major depressive disorder, and healthy controls aged 19-65 years.

Vaping-induced Oxidation of CBD Causes Adduction of TOP2A and Interferes with Cellular Proliferation.

Cannabidiol (CBD) vaping products pose a significant public health risk due to high cannabinoid concentrations, additives and contaminants, unsubstantiated claims of health benefits, and their implication in e-cigarette, or vaping, product use-associated lung injury (EVALI). However, research on the respiratory health effects of vaping CBD is limited. Here we show that the reactive electrophile CBD quinone (CBDQ) is present in significant quantities in commercial CBD vaping products.

The aim of this study was to detect and characterise IDV in the Swedish cattle population using archived respiratory samples. This retrospective study comprised a collection of a total 1763 samples collected between 1 January 2021 and 30 June 2024.

Development of self-gelling powder combining chitosan/ bentonite nanoclay/ sodium polyacrylate for rapid hemostasis: In vitro and in vivo study.

Although hemostatic powders are commonly used in clinical and emergency settings, they frequently show poor absorption, raise cytotoxicity issues, and are not effective for fatal non-compressible bleeding. The purpose of this research is to create a self-gelling hemostatic powder based on chitosan, bentonite, and sodium polyacrylate (CBS) to improve the hemostatic effect. When liquid comes into contact with CBS powders, they can fuse and form a stable hydrogel in less than 30s.

Evidence of sex differences in ozone-induced oxysterol and cytokine levels in differentiated human nasal epithelial cells.

Acute exposure to ozone (O) causes upper and lower airway inflammation. We and others have previously demonstrated that O oxidizes lipids, particularly cholesterol, into electrophilic oxysterols, such as secosterol B (SecoB), which can adduct proteins, thus altering cellular signaling pathways. To investigate how O-derived oxysterols influence cytokine and chemokine release, nasal epithelial cells (HNECs) from healthy donors ( = 18 donors) were exposed to 0.

Melatonin Vapes Contain Potential Contaminants and Alter the Human Bronchial Epithelial Transcriptome.

Melatonin vaping products, touted for their faster absorption than oral melatonin supplements, have been gaining popularity among adolescents as sleep aid. Here, we elucidated the response of human bronchial epithelial cells (hBECs) to high levels of melatonin from vaped aerosols, investigated the uptake of melatonin by hBECs , and characterized the chemical composition of three commercially available melatonin vapes. Melatonin vape exposure decreased the secretion of chemokines and produced an immunosuppressive gene expression signature.

Inhibition of post-lanosterol biosynthesis by fentanyl: potential implications for Fetal Fentanyl Syndrome (FFS).

A recent study discovered a novel, complex developmental disability syndrome, most likely caused by maternal fentanyl use disorder. This Fetal Fentanyl Syndrome (FFS) is biochemically characterized by elevated 7-dehydrocholesterol (7-DHC) levels in neonates, raising the question if fentanyl inhibition of the dehydrocholesterol reductase 7 (DHCR7) enzyme is causal for the emergence of the pathophysiology and phenotypic features of FFS. To test this hypothesis, we undertook a series of experiments on Neuro2a cells, primary mouse neuronal and astrocytic cultures, and human dermal fibroblasts (HDFs) with DHCR7 and DHCR7 genotype.

GAPDH inhibition mediated by thiol oxidation in human airway epithelial cells exposed to an environmental peroxide.

Intracellular redox homeostasis in the airway epithelium is closely regulated through adaptive signaling and metabolic pathways. However, inhalational exposure to xenobiotic stressors such as secondary organic aerosols (SOA) can alter intracellular redox homeostasis. Isoprene hydroxy hydroperoxide (ISOPOOH), a ubiquitous volatile organic compound derived from the atmospheric photooxidation of biogenic isoprene, is a major contributor to SOA.
