Root-Associated Fungal Communities of Different-Aged Silver Birch Stands Naturally Regenerated on Abandoned Farmland

Natural regeneration of forests on abandoned agricultural land represents a cost-effective and sustainable pathway for restoring ecosystem functions and enhancing biodiversity. Root-associated fungi can influence the success of forest regeneration, especially under harsh habitat...

Betaine supplementation modulates mitochondrial and redox-related adaptations in premenopausal women with overweight: a randomized controlled trial

The aim of this study was to investigate the effects of betaine supplementation on mitochondrial and redox-associated parameters in premenopausal women with overweight or obesity. We hypothesized that betaine enhances selected mitochondrial enzyme content and improves antioxidant...

Diversity and distribution of ticks collected from vegetation and domestic animals in Zambia

Ticks are major vectors of pathogens affecting livestock and human health in sub-Saharan Africa, yet integrated data on tick diversity across ecological gradients remain limited. In Zambia, most studies have focused on livestock-associated ticks, with little emphasis on compariso...

Fire-performance lightweight cellulose-based composite for thermal insulation

Abstract Bio-based construction materials show strong market potential and are expected to gain popularity. However, their widespread use in the construction industry requires overcoming key challenges, such as enhancing fire and biodeterioration performance while maintaining rec...

The Effects of the Rearing System, Genotype at the RYR1 Locus and Sex of Fattening Pigs on Selected Biochemical Blood Parameters and Concentrations of Cortisol and β-Endorphin

There has been a growing interest in alternative rearing systems, including free-range rearing. This is particularly important in the case of indigenous pig breeds, which are prized for the high quality of their meat and traditional products, and whose importance in the productio...

Assessment of Antioxidant Potential and Polyphenol and Mineral Content in Selected Green Vegetables Subjected to Sous Vide Cooking and Steaming

Green vegetables are rich sources of bioactive substances, including polyphenols and minerals, whose content and biological activity change during various technological processes. The aim of this study was to evaluate the effect of sous vide cooking at three different temperature...

Identification and quality characterization of a putative novel 17x + 8y high‐molecular‐weight glutenin subunit recombination in bread wheat

Abstract BACKGROUND High‐molecular‐weight glutenin subunits ( HMW ‐ GSs ) are major determinants of dough rheological behavior and bread‐making quality in bread wheat ( Triticum aestivum L.). Among wheat genomes, the Glu‐ B1 locus exhibits the highest allelic diversity; however,...

Foodborne Pathogens in the European Union and Poland: Surveillance Trends, Contamination Sources, and Implications for Food Safety Management

Foodborne pathogens remain a major public health concern in the European Union (EU) despite continued improvements in hygiene, regulation, and surveillance. This narrative review with descriptive surveillance analysis examines major bacterial foodborne hazards in the EU and Polan...

The influence of temperature on river fly phenology based on historic records

Abstract First appearance dates of three river flies (Mayfly, two caddis flies: Grannom and Welshman’s Button) for 1834–1931 were abstracted from the records of a chalk river fly fishing club in southern UK. First appearance dates of the terrestrial invertebrates Mole Cricket and...

Evidence-Weighted Multi-Criteria Decision Support for Subjective Quality Assessment Under Sparse and Unbalanced Information

Decision making for complex products often depends on subjective user experience, while competing alternatives may be supported by strongly unequal numbers of observations. This study develops an evidence-weighted multi-criteria decision-making methodology for such sparse and unb...

Dietary Lepidium meyenii Supplementation Is Associated with Hepatic Transcriptomic and Targeted DNA Methylation Changes in Pigs

Background: Lepidium meyenii Walp. (maca) is a plant-derived feed supplement rich in bioactive compounds such as macamides, macaenes, glucosinolates, and polyphenols. In this study, it was selected as a potential natural functional feed additive based on its bioactive phytochemic...

Characteristics of Bark Stripping Damage by Deer and Nutrient Content in Black Cherry (Prunus serotina Ehrh.)

Large ungulates significantly influence forest ecosystems through shoot biting and bark stripping, but their impact on the dynamics of invasive plant species still remains insufficiently investigated. The North American black cherry (Prunus serotina Ehrh.) is a widespread invasiv...

Hybrid Protection Against Ergot (Claviceps purpurea (Fr.) Tul.) in Winter Rye (Secale cereale L.): Cultivar Susceptibility Under Artificial Inoculation and In Vitro Screening of Chemical, Biological and Botanical Agents

Ergot, caused by Claviceps purpurea (Fr.) Tul., is a re-emerging disease that is particularly severe under wet weather during cereal flowering. It reduces grain quality and contaminates food and feed with toxic ergot alkaloids. Because no single measure reliably controls it, this...

Movement of European freshwater mussels under simulated dewatering conditions

Freshwater ecosystems are exposed to altered hydrological regimes due to climate change and poor water management, resulting in frequent and intense dewatering events. Freshwater mussels (Unionida) are particularly vulnerable to rapid water-level declines. Dewatering can lead to...

Impact of commodity prices volatility on the sovereign risk of European economies: the case of the Russo-Ukrainian conflict

This paper investigates the impact of the Russo-Ukrainian conflict on the relationship between commodity price volatility and sovereign risk in European economies. Focusing on key agricultural commodities (wheat, rapeseed, and maize) and energy commodities (oil, gas, and coal) we...

Modelling resilient species for the restoration of the Green Dam in Algeria

Algeria has long suffered from ongoing desertification, resulting in the progressive loss of vegetation and soil erosion. This has had a severe impact on rural livelihoods in the north, making local communities more vulnerable and causing a decline in biodiversity. In an attempt...

Comparative Flammability and SEM–EDS Characterization of Contemporary, Aged and Charred Oak Wood from Historic Timber Structures

Historic timber combines structural function with heritage value, yet its fire behaviour is inferred from contemporary wood data. This study provides an integrated, condition-based assessment of contemporary oak (Quercus robur L.) and historic oak from a nineteenth-century half-t...

Miocene Evolutionary History Shaped the Phylogeography of Willow Species (Salix L.) in the European Alps

In the European Alps, plant species have persisted through major geological and climatic changes, leaving distinct genetic signatures of divergence. While these patterns are often attributed to Pleistocene glacial refugia, they may also reflect older, pre-Quaternary events. In mo...

Generation of transgene-free MtABCG46 mutants in Medicago truncatula using CRISPR/Cas9

ATP-binding cassette (ABC) transporters form one of the largest and most functionally diverse families of membrane proteins in plants, with members of the ABCG subfamily playing central roles in the transport of specialized metabolites and stress adaptation. In legumes functional...

High-field asymmetric waveform ion mobility spectrometry (FAIMS) improves proteome-wide N-homocysteinylation mapping in mouse liver and brain proteins

Abstract N -Homocysteinylation induces immunogenic, thrombogenic, and amyloidogenic properties of proteins. Although important to gain insight into the mechanisms of homocysteine (Hcy) toxicity, proteome-wide studies of the effects of Hcy-thiolactone (HTL) protein modification re...
