Measuring Eco-Anxiety with the Polish Version of the 13-Item Hogg Eco-Anxiety Scale (HEAS-13): Latent Structure, Correlates, and Psychometric Performance.

Background/objectives: The Hogg Eco-Anxiety Scale (HEAS-13) is a thirteen-item measure of eco-anxiety, with four dimensions: (1) affective symptoms, (2) rumination, (3) behavioural symptoms, and (4) anxiety about personal impact. Being a recently developed questionnaire, data on its psychometrics are limited. The aim of this study was to introduce a Polish version of the HEAS-13 and examine its psychometric properties.

The Effects of Gender-Affirming Hormone Therapy on Quality of Life: The Importance of Research on Youth.

Gender-affirming hormone therapy (GAHT) plays a significant role in the medical care of transgender individuals, helping to align their physical characteristics with their gender identity. While numerous studies have investigated the impact of GAHT on adults, research focusing on its effects on the quality of life (QoL) of transgender youth is limited. In this opinion paper, we aim to address selected challenges associated with gender-affirming medical care, such as (1) the necessity for evidence-based youth gender-affirming medical care, (2) the urge to explore different approaches to gender-affirming medical care diversely in transgender youth research, and (3) understanding the challenges of the detransition process (which refers to stopping or reversing gender-affirming medical or surgical treatments), as well as suggest possible solutions for meaningful progress.

Frankfurter-Type Sausage Enriched with Buckwheat By-Product as a Source of Bioactive Compounds.

Buckwheat by-products may be used as promising food ingredients due to their nutritional composition. Buckwheat husk (BH) may be used in meat products as a source of valuable compounds. In this study, the addition of BH to the quality of frankfurter-type sausages was investigated, aiming to reduce buckwheat waste and to develop nutritionally enriched sausages.

The Diversity of the Mitochondrial Outer Membrane Protein Import Channels: Emerging Targets for Modulation.

The functioning of mitochondria and their biogenesis are largely based on the proper function of the mitochondrial outer membrane channels, which selectively recognise and import proteins but also transport a wide range of other molecules, including metabolites, inorganic ions and nucleic acids. To date, nine channels have been identified in the mitochondrial outer membrane of which at least half represent the mitochondrial protein import apparatus. When compared to the mitochondrial inner membrane, the presented channels are mostly constitutively open and consequently may participate in transport of different molecules and contribute to relevant changes in the outer membrane permeability based on the channel conductance.

Mitochondrial Processes during Early Development of : From Bioenergetic to Proteomic Studies.

The slime mold life cycle includes different unicellular and multicellular stages that provide a convenient model for research concerning intracellular and intercellular mechanisms influencing mitochondria's structure and function. We aim to determine the differences between the mitochondria isolated from the slime mold regarding its early developmental stages induced by starvation, namely the unicellular (U), aggregation (A) and streams (S) stages, at the bioenergetic and proteome levels. We measured the oxygen consumption of intact cells using the Clarke electrode and observed a distinct decrease in mitochondrial coupling capacity for stage S cells and a decrease in mitochondrial coupling efficiency for stage A and S cells.

The The TOB/SAM complex composition in mitochondria of Dictyostelium discoideum during progression from unicellularity to multicellularity.

Despite its complex life cycle including unicellular and multicellular stages, the slime mold Dictyostelium discoideum, a well-known model in biomedical research, has not been used as a model organism in studies on mitochondrial import, including its significance in cellular processes. Moreover, data concerning mitochondrial protein import machinery in D. discoideum mitochondria is limited and nothing is known about the impact of that machinery on slime mold life cycle.

Modeling the chromatographic enantioseparation of aryl- and hetarylcarbinols on ULMO, a brush-type chiral stationary phase, by 3D-QSAR techniques.

The enantiomers of a series of chiral aryl- and hetaryl-carbinols were separated on a chiral stationary phase (ULMO) based on (S,S)-3,5-dinitrobenzoylated 1,2-diphenylethane-1,2-diamine. In all cases, the homochiral analogs of (S)-1-phenylethanol (mostly also S-enantiomers) were retained more. Log alpha values were modeled with the aid of the 3D-QSAR techniques CoMFA (comparative molecular field analysis) and CoMSIA (comparative molecular similarity indices analysis) as well as a descriptor based on normal mode eigenvalues (EVA).
