IL-6 Does Not Influence the Expression of and Other Mg-Homeostatic Factors.

Int J Mol Sci

December 2024

Biomedical Centre Martin, Jessenius Faculty of Medicine in Martin, Comenius University Bratislava, 03601 Martin, Slovakia.

Together with chronic inflammation, disturbed magnesium homeostasis is a factor accompanying chronic disease which thus contributes to a reduced quality of human life. In this study, our objective was to examine the possible IL-6-mediated chronic inflammation-dependent regulation of nine magnesiotropic genes encoding for constituents of magnesium homeostasis of the cell. We used three cell lines (HepG2, U-266, and PANC-1), all characterized by high expression of the gene and the presence of a membrane form of IL-6R capable of responding to human IL-6.

Complexity of electrodermal activity to mental stress is changed during adolescent age-period.

Gen Physiol Biophys

November 2024

Department of Physiology, Jessenius Faculty of Medicine in Martin, Comenius University in Bratislava, Martin, Slovakia.

Complexity characterizes behaviour of all physiological systems whose components interact in multiple ways usually quantified by entropy techniques. However, complexity analysis regarding electrodermal activity (EDA)-related sympathetic cholinergic nervous system is rare. Thus, we aimed to study EDA dynamics complexity changes from aspect of various embedding dimensions (m) and timescales (τ) (sample entropy (SampEn) with m ∈ <2,7>, and multiscale entropy (MSE) in τ ∈ <1,20>) in association with traditionally used EDA indices (skin conductance level (SCL) and non-specific skin conductance responses (NS.

December 2024

Biomedical Centre Martin, Jessenius Faculty of Medicine in Martin, Comenius University in Bratislava, Martin, Slovakia; Department of Pharmacology, Jessenius Faculty of Medicine in Martin, Comenius University in Bratislava, Martin, Slovakia. Electronic address:

Silica-induced lung damage may be associated with changes in distinct metabolites potentially serving as biomarkers. Due to the lack of metabolomic data from animal models, this pilot study aimed to evaluate changes in markers of inflammation and fibrosis, as well as plasma metabolites in rats at 14 and 28 days after silica instillation. Adult male Wistar rats were administered a single oropharyngeal intratracheal dose of silica suspension or sterile saline in controls.

Article Synopsis
  • Allergic asthma is a chronic condition that leads to airway inflammation and hyperresponsiveness, and the study examines the effects of a new ROCK inhibitor, GSK429286 A, on this disease in guinea pigs.
  • The guinea pigs were treated with different doses of GSK429286 A after being sensitized with ovalbumin to evaluate its impact on airway responsiveness, inflammation, and remodeling.
  • Results showed that GSK429286 A effectively reduced airway hyperresponsiveness, suppressed inflammatory cytokines, and decreased markers of airway remodeling, indicating its potential therapeutic benefits for allergic asthma.

Motivation: The association between weather conditions and stroke incidence has been a subject of interest for several years, yet the findings from various studies remain inconsistent. Additionally, predictive modelling in this context has been infrequent. This study explores the relationship of extremely high ischaemic stroke incidence and meteorological factors within the Slovak population.

Pulmonary surfactant serves as a barrier to respiratory epithelium but can also regulate airway smooth muscle (ASM) tone. Surfactant (SF) relaxes contracted ASM, similar to β-agonists, anticholinergics, nitric oxide, and prostanoids. The exact mechanism of surfactant relaxation and whether surfactant relaxes hyperresponsive ASM remains unknown.

Despite developing new diagnostics, drugs, and vaccines, treating tuberculosis (TB) remains challenging. Monitoring inflammatory markers can contribute to more precise diagnostics of TB, identifying its active and latent forms, or monitoring its treatment success. We assessed alterations in plasma levels of 48 cytokines in 20 patients (17 males) with active pulmonary TB compared to age-matched healthy controls (n = 18).

  • Miyoshi myopathy/dysferlinopathy (MMD) is a rare muscle disease linked to mutations in the DYSF gene, which also affects the brain's structure and function, although this impact hasn't been fully studied.
  • Using MRI techniques, a family study revealed significant differences in the brain of MMD patients, including an asymmetrical increase in the size of their inferior lateral ventricles and notable decreases in magnesium levels and energy metabolism in brain regions like the hippocampus.
  • Following a month of magnesium supplementation, the MMD patients showed improvements, suggesting potential benefits and calling for more research into the brain functions of MMD patients and further testing of magnesium therapy.

A thin film of pulmonary surfactant lines the surface of the airways and alveoli, where it lowers the surface tension in the peripheral lungs, preventing collapse of the bronchioles and alveoli and reducing the work of breathing. It also possesses a barrier function for maintaining the blood-gas interface of the lungs and plays an important role in innate immunity. The surfactant film covers the epithelium lining both large and small airways, forming the first line of defense between toxic airborne particles/pathogens and the lungs.

Amyotrophic lateral sclerosis is a severe neurodegenerative disease whose exact cause is still unclear. Currently, research attention is turning to the mitochondrion as a critical organelle of energy metabolism. Current knowledge is sufficient to confirm the involvement of the mitochondria in the pathophysiology of the disease, since the mitochondria are involved in many processes in the cell; however, the exact mechanism of involvement is still unclear.
