Expression analysis of genes involved in sesquiterpene lactones biosynthesis in the Chamisso arnica (Arnica chamissonis Less.) – MINIATURA 5 – research data
No full textMany secondary metabolites that have potential medical use belong to the group of sesquiterpene lactones and are produced by plants belonging to the Asteraceae family. Biosynthesis of some sesquiterpene lactones has already been elucidated, e.g. production of artemisinin in Artemisia annua, costunolide in Saussurea lappa or parthenolide in Tanacetum parthenium . However, there is no information on the molecular basis of the biosynthesis of sesquiterpene lactones in species belonging to the genus Arnica. The main aim of the study was expression analysis of genes involved in the final stages of biosynthesis of sesquiterpene lactones in Chamisso arnica. The research data shows changes in the expression of the FDS, GAO and GAS genes

Immunological, oxidoreductive, biochemical indicators, microbial enzymes in biological material taken from rats fed a diet with the addition of various sources of fiber and copper nanoparticles
No full textDietary copper (Cu) is required for normal functioning of numerous basic biochemical and physiological processes in theorganism. Recently, nanoparticles have emerged as important players in modern science, including nutritional status ofthe host. In the series of the own experiments, we have shown the pros and cons of dietary copper nanoparticles (Cu-NP) on the intestinal, circulatory system, internal organs and brain functioning. For instance, we have shown that incomparison to commonly used dietary CuCO3, Cu nanoparticles (at recommended Cu dietary level) to a greater extentwere absorbed from the intestine, accumulated in brain tissue, exerted antimicrobial effect in the caecum, enhancedlipid oxidation processes and caused morphological damages in the liver and lungs of rats. On the other hand, replacingCuCO3 with copper nanoparticles advantageously protects proteins and DNA against oxidation and nitration processesin laboratory rats. Due to wide physiological effect of the Cu-NP in the whole organism it might be important to regulateits area of reactivity. The intestinal environments themselves, both as the upper and lower gut, modulate metabolicbody response through e.g. activation of intestinal immunological cells and stimulation or thwarting of the “forgottenorgan” – large intestinal microbiota. One of the paramount dietary components is fibre, and its type would play a crucialrole in the assimilation and then physiological activity of Cu-NP. Therefore the main aim of this project is to verify thestatement that the physical, chemical and biological properties of dietary fibre largely affect the intestinal and internalorgans activity of Cu-NP, thus modulate the health status of the body. We hypothesized that a dietary combination ofcopper nanoparticles with either a control inert (cellulose) or a prebiotic (inulin) or a viscous (high viscosity pectin) or abulking (psyllium) fibre would affect physiological responses in the gastrointestinal tract and thus regulate effect of thisform of dietary Cu in the organism.The rat Wistar (Cmdb:Wi CMDB) will be used as a research model, i.e. an established host model for nutritional andmetabolic studies, including the gastrointestinal and hepatic responses to nutritional interventions. The following partialstatements will be verified:- different physicochemical properties of dietary fibre shape metabolic responses in the host consumed different dosesof Cu-NP;- different fibfibre types exert alleviating effects in the host subjected to higher than recommended Cu (as Cu-NP) dietaryaddition;- the changes in the small intestine exerted by different dietary fibre would modulate Cu-NP effects on small intestinalmorphology, permeability/integrity, epigenetic changes as well as immunological and redox status;- the differentiation in large intestinal bacterial population and its activity under dietary fibre manipulations play animportant role in subsequent activity of copper nanoparticles in the body, e.g. in the liver, femur, aorta;- under undesired dietary condition, e.g. high dosage of copper nanoparticles, the caecal microbiota would showdifferent adaptation mechanisms.The animals will be fed standard semi-purified diet with dietary addition of two copper nanoparticles dosages (Curecommended and two times higher) and combined with different types of dietary fibre (control, with prebiotic effect,with bulk effect, with viscous effect). During the experimental feeding (on living animals), the attention will be paid tofaecal and urinal excretion patterns of Cu, as well as faecal microbial enzymatic and metabolic activity. At thetermination of the study, the samples of intestinal digesta (upper and lower intestines) and tissues (blood, intestines,liver, femur, aorta) will be thoroughly examined with regard to microbial, morphological, immunological and redoxstatus, as well as epigenetic changes.The main intention of the project’s authors is to bring as much as possible new insight with regard to the question whichproperties of dietary fibre would support the “good face” and alleviate the “bad face” of ingested copper nanoparticlesin the organism

Probiotic bacteria as tool to extend shelf life and increase consumer quality of low-processed foods
No full textAs part of the R&D works, the possibility of applying probiotic organisms on a group of products was tested to extend their shelf life while maintaining high consumer quality. In particular, the study was focused on improving the microbiological purity of products, limiting the enzymatic browning process and improving health-promoting properties (task 1). The analysis included 11 products: 4 types of shredded lettuce (arugula, edivia, iceberg, lamb's lettuce), 4 types of sprouts (red beet, broccoli, radish and alfalfa) and 3 shredded root vegetables (carrot, red beet, white radish). The evaluation was made based on the microbiological purity (a significant reduction in the number of coliform bacteria, an increase in the number of L. plantarum), preservation of health-promoting (antioxidant) properties and lowering of the browning index
Phytoextraction of heavy metals after application of bottom ash and municipal sewage sludge considering the risk of environmental pollution
No full textWaste management to reduce the loss of natural resources has become a basis of sustainable21 development and a circular economy. When using waste, the heavy metal (HM) concentration22 must be taken into account since HMs can be potentially released to the environment, posing23 a toxicity threat. The aim of the study was thus to estimate the availability for plants of Cr, Ni,24 Cu, Zn, Cd, and Pb introduced into the soil with waste. We hypothesized that the prepared25 waste mixtures containing coal or biomass ash and municipal sewage sludge would reduce the26 environmental risk compared to the studied waste used separately. The research was conducted during a 6-year field experiment with grasses 1 and legumes. HM concentration in2 soil, waste, and plant biomass; tolerance index; and uptake of HMs by plants were measured.3 The ash–sludge mixtures had a more favourable effect on the soil in terms of pHKCl, TOC,4 total nitrogen, and total exchangeable bases than the waste used separately. This provided5 beneficial conditions for plant growth and development. Consequently, the ash–sludge6 mixtures increased the plant yield as compared to ash alone, while the mixture containing the7 biomass ash also enhanced the yield in relation to the sewage sludge. The study showed that8 the mixtures allowed for a reduction of environmental risk arising from the HM input with9 waste to the soil. It was proven that HM availability for plants could be beneficially modified10 by mixing waste. Combining the coal ash with the sewage sludge is particularly11 recommended, owing to the unfavourable properties of coal ash for plants. The application of12 the higher dose of the coal ash–sludge mixture showed a better effect than the lower dose,13 while the influence of both doses of the biomass ash–sludge mixture was similar. Under the14 ash–sludge treatment, plants took up more HM than under the ash used separately, and the15 HM concentration in the obtained biomass did not generally exceed that observed under16 single wastes. This should reduce the accumulation of HMs in the soil during a long-term use17 of the waste and facilitates the utilisation of the produced biomass.Waste management to reduce the loss of natural resources has become a basis of sustainable21 development and a circular economy.

The wild population of the American mink Neogale vison in the south-eastern Poland
No full textThese are results concerning the origin, distribution, and abundance of wild American mink in the Lublin region. The studies were carried out in the years 2021-2022. The main aim of the study was the initial verification of the hypothesis that the genetic differentiation of the wild American mink population in the south-eastern part of Poland has decreased. Genetic similarity of the population from this part of Poland with the minks from north-eastern Poland was examined. Furthermore, the morphological variability of the American mink was determined based on measurements of the body length and weight

Anthropogenic transformations of river ecosystems are not always bad for the environment: Multi-taxa analyses of changes in aquatic and terrestrial environments after dredging of a small lowland river
No full textRivers are one of the most commonly transformed aquatic ecosystems. Most papers present significantly negative effects of activities such as dredging or channel regulation on the ecological status of rivers. The purpose of this work was to compare the response of various groups of invertebrates (Mollusca, Hydrachnidia, Odonata, Heteroptera, Coleoptera and Trichoptera) to an intervention involving dredging in conjunction with the removal of riparian vegetation. Habitat diversity increased after the dredging, and more individuals and species were caught than before the dredging. The increase in habitat diversity after the dredging translated into an increase in the species diversity of most investigated groups. Individual groups of invertebrates showed varied responses to the dredging, depending on the role of the terrestrial phase in their life cycle: the greater the role of the terrestrial phase in the life cycle, the more the group was affected by changes in the terrestrial environment following the intervention. In consequence, the intervention had the greatest negative impact on insects, and among these, on adult Odonata. The following conclusions can be drawn: (1) Dredging can benefit a previously anthropogenically transformed river ecosystem by increasing habitat diversity; (2) Odonata are particularly useful for assessing the impact of this type of intervention on invertebrate communities. They can be considered good indicators ofhabitat disturbances in both aquatic and terrestrial ecosystems.il., bibliogr., sum.Rivers are one of the most commonly transformed aquatic ecosystems.
