Adolescents' health literacy is directly associated with their physical activity but indirectly with their body composition and cardiorespiratory fitness: mediation analysis of the Slovak HBSC study data.

Background: Health literacy is a core public health issue in relation to children and adolescents associated with multiple health behaviours and health outcomes. The aim of the study is to test the direct associations between health literacy, physical activity behaviour, health outcomes of body composition and cardiorespiratory fitness among Slovak adolescents and possible indirect effect of health literacy on health outcomes of body composition and cardiorespiratory fitness mediated by adolescents' physical activity behaviour.

Methods: Data from the Slovak Health Behaviour in School-aged Children (HBSC) study conducted in 2022 were used.

Social mechanisms behind the poor health of marginalized Roma: Novel insights and implications from four ethnographic studies in Slovakia.

Roma represent one of the largest ethnic groups facing marginalization worldwide. However, significant knowledge gaps persist regarding: A) the social mechanisms supporting health-endangering practices among Roma; B) the social mechanisms adversely affecting their use of health services; and C) the social determinants underlying both above pathways. To fill these gaps, we conducted a series of four explorative ethnographic studies spanning over ten years.

Bioactive Carbon@CeO Composites as Efficient Antioxidants with Antiamyloid and Radioprotective Potentials.

Blending carbon particles (CPs) and nanoscale bioactive cerium dioxide is a promising approach for designing composites for biomedical applications, combining the sorption and antioxidant potentials of each individual component. To address this issue, it is crucial to assess the correlation between the components' ratio, physicochemical parameters, and biofunctionality of the composites. Thus, the current research was aimed at fabricating C@CeO composites with different molar ratios and the examination of how the parameters of the composites affect their bioactivity.

Controlled stigmergy in quasi-one-dimensional active particle systems.

In quasi-one-dimensional circularly symmetric systems of active particles, experiments and simulations reveal an indirect interplay between particles and environmental drag effects, proving crucial in the realm of generalized parametrically controlled stigmergy. Our investigation goes deeper into understanding how stigmergy manifests itself, closely examining unconventional, more physically grounded interpretations in contrast to established concepts. Deeper insights into the complex dynamics of stigmergically interacting particle systems are gained by systematically studying the transition regions between short- and long-term stigmergic effects.

In(III) pyridinecarboxylate complexes: Composition, solution equilibria estimation, bioevaluation and interactions with HSA.

Two In(III) - pyridinecarboxylates ([In(Pic)(NO)(HO)] (InPic; HPic = picolinic acid), [In(HDpic)(Dpic)(HO)]·5HO (InDpic; HDpic = dipicolinic acid), have been synthesized by one-step procedure.

pH modulates efficiency of singlet oxygen production by flavin cofactors.

Flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN) are frequently used interchangeably in the catalysis of various reactions as part of flavoenzymes because they have the same functional component, the isoalloxazine ring. However, they differ significantly in their conformational properties. The inclusion of two planar rings in the structure of FAD greatly increases the range of possible conformations compared to FMN.

The Pivotal Role of the Key Angiogenic Factors in the Development of Endometrioid Pathologies of the Uterus and Ovary.

A characteristic feature of uterine pathologies is a specific change in cell metabolism, which predominantly manifests as a shift in the need for nutrients, thereby directing cells to engage in different angiogenic marker activities. Angiogenesis is one of the main signals supporting the survival and development of cells and tissues not only under physiological conditions. Therefore, it is necessary that we understand pathological hyperactivation in all uterine diseases, from endometriosis through ovarian endometrioid adenocarcinoma to malignant transformed cells of the uterine epithelium and body.

Structural, optical and magnetic properties of a new metal-organic Co-based complex.

A mononuclear cobalt(ii) complex [CHN][CoCl(CHN)] (I) was synthesized and structurally characterized.
