The scientific objective of the paper was to compare the use value of native and some foreign horse breeds competing in Polish regional show jumping tournaments. A total of 156 horses were analysed including the native breeds Małopolski (m), Wielkopolski (wlkp), Polish Half Bred Horse (pksp), and the foreign breeds Oldenburger (old), Holsteiner (hol) and Dutch Warmblood (kwpn). The competition results with distribution of penalty points as well as pedigree databases of Polish Horse Breeders Association and Polish Equestrian Federation were used. The data obtained was subjected to analysis of variance (ANOVA-GLM), and the differences between average values were determined with Tukey’s t-test. It was concluded that the native breeds obtained statistically worse results than foreign ones, proportionally to the level of competition difficulty. The proportion of native breeds among the participants of competitions decreased with increasing course difficulty and was statistically significant for the number of eliminations and clear rounds. The results allow a conclusion about the lower use value of native compared to foreign horse breeds for sports purposes.

Breeding value of sport horses in Poland is estimated on the basis of, among others, results of the 100-day performance test of young stallions in the training centres. However recently, a drastic decrease has been reported in the number of stallions undergoing this way of assessment in Poland with an increase in foreign breeds in equestrian competitions. The objective of the study was to determine variability level of stallion traits evaluated in the training centres and to identify factors affecting stallion performance value assessment during the stationary performance test. The study included 503 stallions subjected to the 100-day training followed by the performance test in the years 2004-2013 at the training centres. There were computed statistical characteristics of 16 performance traits which were scored by the trainer of the training centre, judging commission and test riders. Influence of identified factors on each evaluation was established using the GLM procedure. The rank correlations served to estimate phenotypic interdependencies between the scores and performance value indices. It was stated that the studied group of stallions showed low variation within the body basic measurements and the conformation correctness evaluated on the 100-point scale was also found within an average value (78.86 pts), quite close to minimum value for young stallions in Poland (78 pts). The highest variation was observed for the scores given by the test riders and the main factor differentiating the performance value of horses was their origin-breed group. The horses of the German breeds (HANN, OLDBG, HOLST) earned the highest scores, while Wielkopolska horses got the lowest scores for performance test. Insufficient consistency between the individual evaluation made by the trainer of training centre and the judging commission may imply completely different period of assessment (trainer - 100 days, judging commission - 2 days) or unsatisfactory competencies of examiners.

In the spring of 2017, amateur metal detectorists discovered a Late Bronze Age hoard near the village of Kaliska, Poland. Comprising over 120 artefacts, it is one of the most impressive Bronze Age finds within Pomerania. The authors discuss the hoard's contents and context, as well as its chronology.

The aim of this study was to obtain a series of activated carbon samples by the chemical activation of low-rank coal. The precursor was impregnated with a NaOH solution. Activated carbons were characterized by determining their textural parameters and content of surface oxygen functional groups and by using an elemental analysis. The carbons were tested as potential adsorbents for the removal of liquid pollutants represented by rhodamine B. The effectiveness of rhodamine B removal from water solutions depended on the initial concentration of the dye, the mass of rhodamine B, and the pH and temperature of the reaction. The isotherm examination followed the Langmuir isotherm model. The maximum adsorption capacity of the rhodamine B was 119 mg/g. The kinetic investigation favored the pseudo-second-order model, indicating a chemisorption mechanism. The thermodynamic assessment indicated spontaneous and endothermic adsorption, with decreased randomness at the solid–liquid interface. The experiment revealed that a 0.1 M HCl solution was the most effective regenerative agent.

Retinoids are central regulators of skin biology, influencing keratinocyte proliferation, differentiation, immune modulation, and barrier maintenance. Their therapeutic relevance has long been attributed to retinoic acid receptor (RAR)-mediated transcriptional activity; however, recent studies have revealed additional layers of regulation, including epigenetic modifications, kinase signaling networks, and interactions with the skin microbiome. These mechanisms not only refine our understanding of retinoid function but also inform strategies to overcome therapeutic limitations such as resistance, irritation, and systemic toxicity. Advances in medicinal chemistry have yielded synthetic retinoids with enhanced receptor selectivity, particularly for RAR-γ agonists such as trifarotene, as well as inhibitors of cytochrome P450–mediated retinoic acid metabolism, which sustain endogenous activity and mitigate resistance (DX314 and other RAMBAs). In parallel, the development of nanocarriers, stimuli-responsive gels, and other targeted delivery systems has improved drug stability, bioavailability, and tolerability. Together, these innovations underscore the evolving role of retinoid-based interventions in precision dermatology, providing opportunities to optimize treatment outcomes for acne, psoriasis, photoaging, and other dermatological disorders while addressing the shortcomings of earlier generations.

Bone defects and fractures present significant clinical challenges, particularly in orthopedic and maxillofacial applications. While minor bone defects may be capable of healing naturally, those of a critical size necessitate intervention through the use of implants or grafts. The utilization of traditional methodologies, encompassing autografts and allografts, is constrained by several factors. These include the potential for donor site morbidity, the restricted availability of suitable donors, and the possibility of immune rejection. This has prompted extensive research in the field of bone tissue engineering to develop advanced synthetic and bio-derived materials that can support bone regeneration. The optimal bone substitute must achieve a balance between biocompatibility, bioresorbability, osteoconductivity, and osteoinductivity while simultaneously providing mechanical support during the healing process. Recent innovations include the utilization of three-dimensional printing, nanotechnology, and bioactive coatings to create scaffolds that mimic the structure of natural bone and enhance cell proliferation and differentiation. Notwithstanding the advancements above, challenges remain in optimizing the controlled release of growth factors and adapting materials to various clinical contexts. This review provides a comprehensive overview of the current advancements in bone substitute materials, focusing on their biological mechanisms, design considerations, and clinical applications. It explores the role of emerging technologies, such as additive manufacturing and stem cell-based therapies, in advancing the field. Future research highlights the need for multidisciplinary collaboration and rigorous testing to develop advanced bone graft substitutes, improving outcomes and quality of life for patients with complex defects.

The dried and powdered leaves of Moldavian dragonhead (Dracocephalum moldavica L.) (0, 1, 3, 4, and 5 g/100 g of wheat flour) were added to the wheat flour to make bread. Farinograph properties of dough were studied, and the properties of enriched bread were evaluated. According to the results, Moldavian dragonhead leaves increased water absorption by the flour but decreased the volume of bread and crumb lightness. The enriched breads were characterized by a higher value of crumb hardness than that of control bread. The total phenolics content linearly increased with the percentage increase in the addition of dragonhead leaves from 4.8 to 10.1 mg GAE/g dry mass. As a result, the antioxidant activity of bread increased. Sensory evaluation revealed that the wheat bread can be supplemented with Moldavian dragonhead leaves up to 3 g/100 g wheat flour addition of dragonhead leaves with good consumer acceptability.

The growing need for electric energy is forcing the construction industry to greater integrate energy production systems based on renewable energy sources. The energy ought to be used not only to support functions of the building but also to charge electric vehicles, whose number has been increasing for the last few years.

We investigate the full and half-shells of Pb 1− x Sn x Te topological crystalline insulator deposited by molecular beam epitaxy on the sidewalls of wurtzite GaAs nanowires (NWs). Due to the distinct orientation of the IV–VI shell with respect to the III–V core the lattice mismatch between both materials along the nanowire axis is less than 4%. The Pb 1− x Sn x Te solid solution is chosen due to the topological crystalline insulator properties above some critical concentrations of Sn ( x  ≥ 0.36). The IV–VI shells are grown with different compositions spanning from binary SnTe, through Pb 1− x Sn x Te with decreasing x value down to binary PbTe ( x  = 0). The samples are analysed by scanning transmission electron microscopy, which reveals the presence of (110) or (100) oriented binary PbTe and (100) Pb 1− x Sn x Te on the sidewalls of wurtzite GaAs NWs.
