Abstract:

The basis of the mechanism of ischemic brain tissue are hematological disorders. It is known that divalent ions influence the formation and structure of fibrin. In connection with this fact, a change in macro- and microelement balance serves as a marker of neurotrophic disturbances in the brain long before their clinical manifestations. The imbalance of metal-ligand homeostasis is an unfavorable background for the debut of ischemic stroke. In a multifactorial coagulation system, specific proteins - Protein C and D-dimers - occupy a key place. Many macro- and microelements are mediators of homeostasis and thrombosis: violations of elemental homeostasis are the molecular basis of the ischemic process. In a study conducted in a clinical setting, the combined dynamics of protein C and D-dimers and a complex of macro- and microelements are shown with a high degree of certainty. Using Spearman correlation analysis, reliable correlations were revealed between the concentrations of protein C, D-dimers and macro- and microelements in patients diagnosed with ischemic insult. In the final part of the mathematical processing of the results, multiple regression analysis was used, with the help of which a reliable relationship between protein C, a component of the blood coagulation system, and the concentration of a complex of macro- and microelements contributing to the central mechanism of etiopathogenesis of ischemic stroke is shown: R = 0.95938848, R2 = 0.92042626.

Abstract:

A probabilistic mesomechanical crack nucleation model is proposed to link the microstructural material heterogeneities to the statistical scatter in the macro structural response. The macrostructure is modeled as an ensemble of microelements. Cracks nucleate within the microelements and grow from the microelements to final fracture. Variations of the microelement properties are defined using statistical parameters. A micromechanical slip band decohesion model along with a Paris law crack growth model are used with first order reliability methods and Monte Carlo simulation to determine the distribution of fatigue life for the macrostructure. The modeled response is compared to trends in experimental observations from the literature.

Abstract:

Adverse environmental conditions may affect the condition of the hair follicle, which require the optimal amount and ratio of minerals. The description of the diagnosis and treatment of microelements in patients suffering from diffuse telogen alopecia is presented. Based on the analysis of data from the literature review and the results of treatment of groups of patients the importance of identifying microelement imbalance in order to apply effective treatments is shown. The results obtained, showing the imbalance of macro - and micronutrients, including essential, are the basis for recommendations for patients with diffuse alopecia additional examination for definition of microelement composition of hair. This allows to prescribe different composition of microelement complexes that ensure the replenishment of certain microelements deficiency. And this provides an opportunity to reasonably resolve the issue of the need to include in the treatment plan detoxification measures to reduce the content of toxic and conditionally toxic microelements in the body.

Abstract:

Violation of homeostasis is often connected with a deficiency or excess of certain elements. Undeniable value of biologically active substances of plants is that they are contained in plant raw material in natural balanced complexes and they are an important source of macro- and microelements for a human organism. Study of a chemical composition, including macro- and microelements, a pharmacological effect of Verbena species is a basis for conduction of further researches. There are 250 species of Verbena genus, 3 of which, namely Verbena officinalis L., Verbena supina L. and Verbena hybrida Hort are growing in Ukraine. The aim of our research was to study macro- and microelements in the raw material of Verbena genus species, to reveal the influence of the conditions of growing on the content of elements in the Verbena officinalis L. herb, to compare element composition of the Verbena officinalis L. herb and herbal extracts. Macro- and microelement composition of raw material was researched by using the method of atom-emission spectrometry with inductively bounded plasma iCAP 7000 Duo. To determine the influence of the conditions of increase of macro- and microelements in Verbena officinalis L. herb, their quantity in soils and plants from different areas of growing was defined. To reveal the intensity of absorption of macro- and microelements from the soil by the plants, the coefficients of their biological accumulation were calculated. The comparative determination of the element composition of Verbena officinalis L. herb and herbal extracts VOH-0 (extractant – purified water) and VOH-7 (extractant – 70% ethanol) was also carried out to determine the degree of elements transfer from plant raw material into extracts. Results of the research show that in the samples of Verbena officinalis L. herb, Verbena hybrida Hort. herb and Verbena supine L. leaves there are 22 inorganic elements. Results of studying of element composition of Verbena officinalis L. herb and samples of soil from different areas of growing in Ivano-Frankivsk and Ternopil regions show that the quantitative and qualitative compositions of microelements depend on element exchange of these plants, conditions of growing and element composition of soil. The reverse dependence between the content of most elements in the soil and the coefficient of their accumulation in plants was found out. Concentration of elements in the herb and extracts was identified to have the same profile, but the quantitative content of elements was different, which was influenced by the extractor (purified water, 70% ethanol). Results of our research are currently relevant; they should be taken into account in the development of new herbal medicines, which would have desirable pharmacological effect in the future.

Abstract:

The number of stomata and the concentration of macro- and microelements in four new winter wheat genotypes: Lenta, Lara, Perla and Fiesta were investigated in two localities in Croatia in the 1997/98 growing season. The stomata number per mm2 was determined by a standard method. N was established by the micro-Kjeldahl method, P spectrophotometrically and K, Ca, Mg, Zn, Cu, Fe and Mn by the AAS method. The interrelation of the investigated parameters was determined by multiple regression and correlation analysis. The results obtained indicate that the number of stomata per mm2 and the macro- and microelement concentrations depended on the genotype, the phenophase and the locality. A statistically significant correlation was found between the stomata number per mm2 and the macro- (N, P, K, Ca, Mg) and microelement (Zn, Cu, Fe, Mn) concentrations.

Abstract:

The exotic flavor of Brazilian tropical fruits led to increased consumption. Consumers awareness regarding balanced diets, makes necessary determining nutritional composition - vitamins and minerals of the fruits ordinarily consumed. This study contributed to the evaluation of macro (K, Ca) and microelements (Mn, Fe, Cu, Zn and Br) in eight exotic Brazilian tropical fruits: "abiu" (Lucuma caimito Ruiz & Pav.), "jenipapo" (Genipa americana L.), "jambo rosa" (rose apple, Eugenia Jambos L.), "jambo vermelho" (Syzygium malaccence L., Merr & Perry), "macaúba" (Acrocomia aculeata Jacq. Lood. Ex Mart.), "mangaba" (Hancornia speciosa), "pitanga" (Brazilian Cherry, Eugenia uniflora L.), and tamarind (Tamarindus indica L.), using the Energy Dispersive X-Ray Fluorescence (EDXRF) technique. "jambo vermelho" and "macaúba" presented the highest values of K concentrations, 1,558 and 1,725 mg 100 g-1, respectively. On the other hand, Ca concentrations were highest in "macaúba" (680 mg 100 g-1) and "jenipapo" (341 mg 100 g-1). The microelemental concentrations in these eight fruits ranged from: 0.9 to 2.0 mg 100 g-1 for Mn, 3.9 to 11.4 mg 100 g-1 for Fe, 0.5 to 1.0 mg 100 g-1 for Cu, 0.6 to 1.5 mg 100 g-1 for, Zn and 0.3 to 1.3 mg 100 g-1 for Br. The amounts of macro and microelements in the eight fruits analyzed were compared to other tropical fruits and it was found that some of them could be classified as rich sources for these macro and microelements.

Abstract:

The aim of the research is to study the quantitative content of macro- and micronutrients in the seeds of the Celery family. In the work using the method of X-ray fluorescence analysis, the elemental composition of the seeds of celery crops - carrots, parsley, celery, coriander and parsnip was studied. Individual profiles were compiled (series on the accumulation of macro- and microelements) and their similarity was noted for most elements, which indicates a common metabolic process in plants of related species. Of the macrocells in the seeds of the studied species, Ca and K, as well as P, Mg, S, accumulate in the maximum amount, and of the trace elements Fe, Zn, Mn. Differences in the accumulation of elements in different cultures depended on the type of macro- or microelement. The types of accumulation of Ca, P, K, Zn, Pb, Ni, Zr are relatively weak in types, and the concentrations of Si, Na, Al, Br, Ti Sr, and Fe are most variable in cultures. Significant accumulation of Si in parsnip seeds was noted which is not typical for other studied species. In general, parsnip seeds have the richest set of macro- and microelements in comparison with other celery crops. The seed samples analyzed had a wide variety in the mineral composition. Numerous variations among species belonging to the same family are probably due to individual genetic structure, as well as different growing conditions.

Abstract:

Isotopic effects occurring in living organisms due to metabolism are analyzed. The phenomenon of metabolism is considered in the classical sense as a combination of biochemical reactions (mainly enzymatic) that take place in the cells of living beings and provide the cleavage, synthesis and interconversion of complex compounds. The scope of use of natural isotopes is wide and diverse. Isotopes are carriers of information about the birth and transformation of molecules, and isotope fractionation is a chemical characteristic of a substance. Isotope metabolism consists in the intermolecular fractionation of isotopes at separate stages of biochemical reactions, namely the cleavage, synthesis and interconversion of complex compounds caused by differences in the structure and fundamental properties of isotope nuclei. It is proved that the fractionation of isotopes in chemical and biochemical reactions due to isotopic effects is based on two fundamental properties of atomic nuclei — mass and magnetic moment. The kinetic (mass-depen dent) isotopic effect distributes the isotopic nuclei by their masses, and the magnetic one fractionates the nuclei by their magnetic moments. The kinetic isotopic effect depends on the magnitude of the difference in the masses of isotopic molecules, temperature and the difference in the activation energies of isotopic forms. The magnetic isotope effect depends on the reaction rate in a single cell, its projection, magnetic moment and energy of electron-nuclear interaction. It is determined that the fractionation of isotopes in living organisms is that the relative content of one of the isotopes in this compound increases by reducing its content in the other. As a result, there is a fractionation of isotopes within one biological object.

Abstract:

Objective: to determine the content of hormones, as well as some macro- and microelements in athletes-wrestlers outside the period of competition and active training.Materials and methods: the study involved 66 athletes-wrestlers and 107 students involved in sports professionally. The level of hormones and vitamin D was determined by the ELISA method. To analyze the content of macro- and microelements, the subjects were cut off a lock of hair from the back of the head in an amount of at least 0.1 g. The studies were carried out on an ICP-MS Agilent 7900 mass spectrometer.Results: levels of cortisol, TSH and T4 are higher, and levels of testosterone, T3 and vitamin D are lower in athletes compared to the control group. An increase in the content of sodium, calcium, potassium, magnesium, cobalt and a decrease in iodine were revealed in fighters from those who were not involved in sports professionally.Conclusion: the data obtained indicate an imbalance in the work of the body’s endocrine systems and impaired adaptation to stress. It is known that the determination of the hormonal status is used to assess the adaptation, the revealed changes in the indicators of vitamin D, macro- and microelements, allow the study of these indicators in order to prevent the syndrome of overtraining of athletes, to maintain and improve sports performance.

Abstract:

AbstractThe concentrations of seven macro- and microelements (K, Mg, Ca, Na, Fe, Zn, Mn) in 59 herbs (herbs, leaves, flowers, fruits, roots), which are commercially available and frequently used in Poland for medical purposes as well as in their water extracts (infusions and decoctions), were determined after microwave mineralization. The data obtained show that all herbal raw materials analysed contain macroelements in the range of mg g−1 on d.w. whereas microelements in the range of mg kg−1 on d.w. and that elemental concentrations varied widely. On the basis of a comparison of concentrations of elements in herbal raw materials examined and water extracts prepared from them, the extraction efficiency was expressed as a percent of the total content of each element present in the infusion or decoction. The percentages of macro- and micro- elements leaching from different morphological parts of plants into water extracts varied across a wide range of values, from 1% in the case of Na to 56% in the case of K. Real daily intake of the macro- and microelements elements through one cup of infusions or decoctions were shown that water extracts from herbal raw materials are not an important source of bioelements in human diet.

Abstract:

Comparative analysis between bottled and tap waters as well as its comparison with current Serbian regulations, European Union Directives and World Health Organization standard are shown in this paper. Thirteen bottled waters and fourteen tap waters from the territory of Serbia were analyzed in the Federal Institute for Geosciences and Natural Resources (BGR) laboratory in Berlin, for the purpose of the ?Geochemistry of European Bottled Water? project conducted by EuroGeo Survey Geochemistry (EGS). Macrocomponents (main cations and anions) of ground waters usually reflect on lithogeochemistry of the aquifer, while microcomponents indicate the circulation of ground water through the different lithological environment. Analyzed bottled waters could be classified as those with low mineral content (M<500 mg/L) if HCO3 anion and Ca and Mg cations were the prevailing ones, or mineral (M>500 mg/L) with prevailing HCO3 anion and Na cation. Waters with low mineral content were mainly from limestone and dolomite, while mineral waters mainly originated from magmatic and metamorphic rocks. Higher content of Cs, Li, Ge, Rb and F in bottled waters indicates the importance of the magmatic intrusions influence on their chemical composition. In some waters higher content of B, I, NH4, as well as of Tl and W has been observed which can be attributed to water?s circulation through different lithological complexes. Tap water was mostly obtained from groundwater (from Neogen and alluvial aquifers and karst springs) with rest being those of rivers and surface accumulations. Tap waters from Central Serbia were with low mineral content, with prevailing HCO3 anion and Ca and Mg cations, while waters from Vojvodina, the northern province of Serbia, were with higher mineralization, HCO3-Na. Chemical analyses of the sampled tap waters showed good quality, with exception of waters from the cities of Senta and Zrenjanin in Vojvodina. High values of B (1170 and 895 g/L), As (20.9 and 71.9 g/l), Na (208 and 275 mg/L), as well as EC (715 and 928 S/cm) have been registered in these waters.

Abstract:

Adequate intake of macro- and microelements during pregnancy meets the growing needs of a female organism and lays the basis for a child’s health. According to the World Health Organization, in malnutrition or chronic health conditions (i. e. gastrointestinal disorders, diabetes, hypo-thyroidism etc.) in a pregnant woman, additional intake of essential micronutrients is required. Cochrane Reviews demonstrate that multivitamin supplements reduce the occurrence of intrauterine growth restriction and low birthweight. Zinc is a microelement whose adequate intake is of crucial importance. Mild zinc deficiency manifests as recurrent respiratory infections, taste and smell loss, night blindness, impaired spermato-genesis, and (sometimes) mild psoriasis-like dermatitis. Severe zinc deficiency is characterized by more often respiratory infections and more severe skin conditions (e. g., acrodermatitis with erythematous, squamous, vesicular bullous, or pustular rash in perioral and perianal areas), alopecia, persistent diarrhea, stomatitis, and glossitis, growth and developmental delay, and various psychoneurological disorders.Keywords: pregnancy, newborn, infant, vitamin mineral supplement, microelements, zinc, atopic dermatitis, deficiency.For citation: Borovkova E.I., Zaplatnikov A.L., Zhdakaeva E.D.

Abstract:

Western Siberia is one of the major spring wheat regions of Russia, cultivating over 7 Mha. The objective of the study was to evaluate the variation of macro- and microelements, and of trace metals in four distinct groups of genetic resources: primary synthetics from CIMMYT (37 entries), primary synthetics from Japan (8), US hard red spring wheat cultivars (14), and material from the Kazakhstan–Siberian Network on Spring Wheat Improvement (KASIB) (74). The experiment was conducted at Omsk State Agrarian University, using a random complete block design with four replicates in 2017 and 2018. Concentrations of 15 elements were included in the analysis: macroelements, Ca, K, Mg, P, and S; microelements, Fe, Cu, Mn, and Zn; toxic trace elements, Cd, Co, Ni; and trace elements, Mo, Rb, and Sr. Protein content was found to be positively correlated with the concentrations of 11 of the elements in one or both years. Multiple regression was used to adjust the concentration of each element, based on significant correlations with agronomic traits and macroelements. All 15 elements were evaluated for their suitability for genetic enhancement, considering phenotypic variation, their share of the genetic component in this variation, as well as the dependence of the element concentration on other traits. Three trace elements (Sr, Mo, and Co) were identified as traits that were relatively easy to enhance through breeding. These were followed by Ca, Cd, Rb, and K. The important biofortification elements Mn and Zn were among the traits that were difficult to enhance genetically. The CIMMYT and Japanese synthetics had significantly higher concentrations of K and Sr, compared to the local check. The Japanese synthetics also had the highest concentrations of Ca, S, Cd, and Mo. The US cultivars had concentrations of Ca as high as the Japanese synthetics, and the highest concentrations of Mg and Fe. KASIB’s germplasm had near-average values for most elements. Superior germplasm, with high macro- and microelement concentrations and low trace-element concentrations, was found in all groups of material included.

Abstract:

The subject of this research is the composition of micro- and macro- rare earth elements in the Late Pleistocene syngenetic ice wedges of the Seyakha yedoma, explored in the outcrop of the Gulf of Ob in the east of Yamal Peninsula (70°9'27.88 "N, 72° 34'8.31" E), north of the Western Siberia. The All-Russian Scientific-research Institution of Mineral Resources after named N.M. Fedorovsky examined the composition of chemical elements in the ice wedges using the methods of atomic-emission spectrometry and mass spectrometry with inductively linked plasma (spectrometers Elan-6100, Optima-4300DV, Perkin-Elmer, Polyvac E-1000, Rank Hilger). The following conclusions were made: 1) Ice wedges of the Seyakha yedoma are rich in macro - and microelements was recorded, which exceeds such in ice wedges of Yakutia by 8-10 times. The high composition of microelements indicates the role of aerosol and soil particles in the formation of chemical composition of ice. The differences between the ice of Yamal and Northeastern Yakutia also testify that the chemical composition reflects the involvement of marine aerosols in ice formation. 2) Rare-earth elements accumulate in the ice of Seyakha yedoma. The composition of all rare-earth elements exceeds the Clarke number in river waters by 69 (Tm ) – 382 (Y) times. 3) Variability of microelement composition within the ice wedge is insignificant, which implies that the water of the polluted with dust and aerosols spring-summer snow is filtered through the entire snow layer and is partially cleaned prior to getting into the ice-break in the ground under the snow.

Abstract:

Significance. According to WHO, unbalanced diet is one of the leading causes of chronic diseases. Adolescence should be considered a person’s life most important period in terms of developing eating habits that define the body macro- and micronutrient intake. The purpose of the study was to assess diet type and balance and specify region-related macro- and micronutrient diet profiles among young Caucasian and Aborigine males in the North-East of Russia. Material and method. ASPON-nutrition software program was used to analyze the availability of proteins, fats, carbohydrates, fiber, vitamins, as well as macro- and microelements in diets of young males residing in the Magadan Region and Chukotka Autonomous District (mean age equals to 17-21 years, n = 278). Results. The study has identified a clear imbalance in the diet characterized by a low intake of the protein-lipid component, a shortage of polyunsaturated fatty acids, and a complete lack of fiber intake against the background of the increased share of mono- and disaccharides as well a deficiency of macro-, microelements and vitamins in the diet. The deviations have proved to be typical of people residing in the city of Magadan, primarily of the young indigenous population who experience a 100 percent nutritional deficit for a number of components.

Abstract:

Currently, a significant value for a correct nutrition and human metabolism has available the fermented milk products, as a cottage cheese that is produced by a culture of Lactis Lactococcus lactis subsp and Cremoris Lactococcus lactis subsp with pepsin. Moreover, the enrichment of the functional specificity of such products by vitamins C, E, A, D, K, macro - and microelements is a topical direction. The purpose of this study was to develop new cottage cheese compositions fortified by natural additives: ginger, topinambour and radish. For the achieving of it, following tasks were considered: creating of the cottage cheese production, sensory assessment, analyzing of the organoleptic and physicochemical characteristics, identifying of the macro- and microelements contents in the cottage cheese. From the available sources - ginger, topinambour and radish consist in following antioxidants: retinol (vitamin A), thiamine (B1), folacin (B9), riboflavin (vitamin B2), tocopherol (vitamin E), ascorbic acid (vitamin C) and others. The organoleptic characteristics, such as: appearance and consistency, taste and smell, colour and physicochemical properties confirmed that the developed compositions meet the standard requirements for cottage cheese. Specifically, the samples had a milky-white color, a pleasant uniform consistency with additives particles, without odour and a moderate taste. In addition, the mineral content in the cottage cheese was determined by the Massspectrometry method and using the Scanning Electron Microscope. The presented samples have nutritional values and following valuable macro- and microelements: potassium (15.43-26.90 mg/kg), calcium (6.83-14.37 mg/kg), magnesium (0.85-1.24 mg/kg), phosphorus 97.91-21.77 mg/kg), sodium (3.25-7.36 mg/kg) and others.

Abstract:

The progressive prevalence, significant economic losses, the cost of compulsory health insurance and high-tech medical care have turned the problem of lumbar osteochondrosis into a socially significant issue. The relevance of this problem is dictated by the need to study the etiopathogenesis of the course of degenerative changes for an integrated approach when choosing an adequate treatment. The progression of the pathological process in the spine significantly contributes to changes in the metabolism of connective tissue, which is closely associated with the violation of microelements. Purpose: Evaluation of changes in the homeostasis of the intervertebral disc, in particular the study of the microelement composition of the intervertebral disc at various stages of development of hernias of the lumbar spine using instrumental neutron activation analysis. Material and methods: The studied biomaterial was obtained intraoperatively, with traditional microdiscectomy in herniations of the spine at the level of VL3-4, VL4-5, VL5-S1. By the method of instrumental neutron activation analysis, a study of biomaterials, represented by tissue fragments of the remote part of the hernia of the intervertebral disc, located at different stages of the degenerative process, was carried out. Results: The quantitative content of 22 macro- and microelements in the removed fragments was determined. As a result of the data obtained, it was found that in the tissues of the intervertebral discs, a gradual change in the content of a number of essential elements occurs, depending on the stage of development of the degeneration process. Conclusion: Changes in the microelement composition indicate metabolic processes occurring in the intervertebral discs, and the relationship of the microelement composition of the disc tissue and the course of the degenerative process can be used to predict the condition of the patient and choose an adequate treatment.

Abstract:

Composting the municipal organic fraction of waste results in a valuable product in the form of compost, which could be used instead of other forms of fertilisation. The organic waste stream may contain oxo-biodegradable and biodegradable plastics used for waste collection. Their components and decomposition residues may contaminate the compost chemically and physically. In this paper, the results of studies on the content of selected macro- and microelements in new and composted plastics have been analysed. Statistical analyses were carried out in order to determine the most characteristic components of plastics and to determine the character of chemical composition changes. The analysis of the test results showed that multidirectional changes in the content of macro- and microelements occur during composting, and they may be the source of contamination of the fertiliser produced. Contaminants in the form of microplastics may also be released into the environment, which may pose a threat to many elements of the environment, including animals and humans.

Abstract:

In this study, near-infrared spectroscopy (NIRS) was used to predict the contents of essential macro- and microelements in common bean (Phaseolus vulgaris L.) accessions of most widespread Croatian landraces. Total of 175 samples were used for the model development by modified partial least square (MPLS), principal component regression (PCR) and partial least square (PLS) techniques. Based on the coefﬁcients of determination (R2), standard error of calibration (SEC) and error of prediction (SEP) the models developed were (i) nearly applicable for nitrogen (N) (0.89, 0.12 and 0.45 respectively), (ii) poor for iron (Fe), cinc (Zn), potassium oxide (K2O) and potassium (K), (iii) usable for phosphorus pentoxide (P2O5), phosphorus (P), phytic acid (PA) and manganese (Mn). The MPLS regression statistics suggested the most accurate models developed comparing with PLS and PCR. It was concluded that a wider set of common bean samples needs to be used for macro- and microelements prediction by NIRS.

Abstract:

Abstract The purpose of fundamental research in agricultural ecology is to solve complex problem of the establishment of patterns of mass transfer in agricultural systems and regulation of these processes in agricultural soil use. The chemical composition of soil is the result of soil-forming processes. The characteristics of the soil-forming material play decisive role. The investigation of the content of macro- and microelements in soils of different types has been quite relevant in recent decades due to their large physiological role in the life of plants and animals and the active transformation of soils during agricultural use. Fertilization is a process of certain soil cultivation and includes a set of measures aimed at the regulation of macro- and microelements, the lack of which can be determined by zonal conditions of soil formation or soil degradation, as a result of irrational agricultural nature management. The paper presents the results of a study of the content of individual macro- and microelements in some types of soils of the Central Black Soil regions. The studies of the aspects of the impact of fertilization existing in the scientific literature are controversial. The consideration of ecologically and economically justified levels of changes in soil properties during cultivation is necessary to control negative transformations of chemical elements in soil and their accumulation in depositing media. A quantitative assessment of the total content of water-soluble salts, their qualitative composition and dynamics under the influence of agrotechnical factors, the study of their spatial differentiation in soil cover allows optimizing the use of fertilizers and increasing the stability of agropedocenoses.

Abstract:

The content of macro- and microelements in dry samples of mushrooms of the species Macrolepiota procera, Boletus edulis and Cantharellus cibarius, collected at different areas in Bosnia and Herzegovina, was determined using the ICP-OES method (inductively coupled plasma optical emission spectrometry). Of the macroelements, K is the most represented, followed by S, P, Mg, and the least represented Ca and Na. Zn is the most represented of the essential microelements, followed by Fe, Se, Cu, Mn and Co. Al is the most abundant of the other trace elements followed by Ni and Cr. Of the toxic metals, the most represented is Cd, followed by Pb and As. There are differences in the concentration of micro- and macroelements in the mushrooms analysed, depending on the area from which they were collected because natural geology and geochemistry influence the content of macro- and microelements in wild edible mushrooms. The results show that the analysed mushrooms can be considered a good source of essential elements. The study also assessed potential health risks of heavy metals and the target hazard quotient (THQ) for As, Cd, Pb, Cu, Zn, Ni and Cr in the analysed mushrooms was lower than the safe level. The carcinogenic risk index revealed that Cd and Ni are the most prevalent pollutants in the mushrooms studied.

Abstract This paper considers the influence of manganese and zinc sulfate, as well as Megamix-Zinc on the protein quality of grain of winter and spring wheat, when cultivating it on soils with a deficiency of certain microelements. It was found that treatment of seeds and growing plants of experimental crops with the studied preparations increased the content of the essential limiting amino acids in the grain of winter wheat - lysine by 85.7%, threonine by 116.7%, isoleucine + leucine by 20.9%, phenylalanine + tyrosine by 33.3% compared to the control variant. A rise in the amount and amino acid score of such limiting amino acids as lysine and threonine is also observed, which leads to a decline in the coefficient of difference of amino-acid scores up to 75.5% and an increase in the biological value of the total protein up to 24.5%. The total amount of amino acids in the grain of spring wheat increased when Megamix-Zinc was used in the cultivation technology, both on soils with natural fertility and with application of mineral fertilizers, which is associated with a rise in nitrogen and carbohydrate metabolism. The increase in relation to the control group is 0.42 - 1.34 mg/g, depending on the variant. Under the influence of the factors used, amino acid score of individual amino acids of the spring wheat protein increases in relation to the control group up to 2.1%.

Abstract:

Introduction. One of the most attractive materials in the composition of toothpastes is hydroxyapatite with nanoscale crystals that contribute to the prolongation of remineralization due to the release of calcium and phosphorus. In some cases, macro- and micronutrients are introduced into preventive toothpastes; however, the dynamics of increasing their concentration in the oral fluid has not been studied enough.The objective was to study the effect of bioactive toothpaste with natural hydroxyapatite, enriched in nanodispersed particles of iron, zinc and copper, on the dynamics of the dental status and the level of copper, iron, zinc, magnesium and calcium in the oral fluid.Methods and materials. 26 patients were examined: 19 patients used the toothpaste being studied, and 7 patients used toothpaste, which did not have macro- and microelements. The determination of the Green-Vermilion hygiene index and the papillary-marginal-alveolar index was carried out, followed by calculation of the effectiveness of the cleansing and antiinflammatory effects. In the oral fluid, the method of electrothermal atomic absorption spectrometry was used for determination of the content of cations of copper, iron, zinc, magnesium and calcium.Results. One month after the start of the use of toothpaste with natural hydroxyapatites enriched with macro- and microelements, a statistically significant increase in the oral fluid of patient, levels of copper, iron, zinc and calcium was established. The effectiveness of the cleansing effect was 85 %, anti-inflammatory effectiveness – 90 %.Conclusion. The increase in the level of macro- and microelements in the oral fluid is due to the composition of the toothpaste containing, along with biogenic hydroxyapatite, nanodispersed particles of iron, zinc and copper.Authors declare no conflict of interest.The authors confirm that they respect the rights of the people participated in the study, including obtaining informed consent when it is necessary, and the rules of treatment of animals when they are used in the study.

Abstract:

Wild greens can contribute to the human diet as an important source of essential nutrients and drugs. Since environmental factors, including soil properties, may affect the chemical composition of plants, it is necessary among others to assess various habitats in terms of their usefulness for wild plant harvesting and to study impact of environmental factors on the qualitative and quantitative chemical composition of plants. This study was aimed at (1) examining the mineral composition of leaves of three dandelion microspecies, (2) determining the variability of macro- and microelement concentrations in dandelion leaves from populations growing on salty, brackish and non-saline coastal meadows, and (3) assessing the effects of different habitat conditions on the mineral composition of dandelion leaves. It was hypothesized that dandelion microspecies would differ significantly in the mineral composition of leaves. It was also expected that soil conditions would significantly affect nutrient concentrations in dandelion leaves, with soil salinity being the most important factor that differentiated studied populations. Leaves of three dandelion microspecies (Taraxacum balticum, T. nordstedtii, T. haematicum) were harvested in Baltic costal grasslands, along the soil salinity gradient, to determine macro- and microelement concentrations. Soil samples collected in the closest vicinity of the harvested plants showed the study sites to differ significantly in their soil properties. Moderately saline and organic soils, rich in potassium (K), magnesium (Mg), and calcium (Ca), supported T. balticum. Moderately or weakly saline and non-saline, organic or mineral soils, with lower median values of K, Mg, and Ca, were typical of T. nordstedtii sites, while the lowest median values of all the soil properties studied were found for T. haematicum sites. Our results proved that dandelion microspecies differ significantly in the mineral composition of their leaves. The between-microspecies differences were significant for all the macroelements except magnesium and all the microelements except molybdenum. Most of the macro- and microelements in leaves of the dandelion microspecies correlated positively and significantly with the soil properties, the strongest correlations being found for soil salinity and the leaf Na, Mn, Ca, Fe, K and Zn contents, followed by soil pH and the leaf Na, Mn, Fe, K, Ca, Zn and Mg. Moreover, the impact of soil properties on the mineral contents in leaves of the dandelions we examined seems to be stronger than the genetic differences between dandelion microspecies. Results of our studies on mineral composition of dandelion leaves lend support to the contention that wild greens provide essential mineral nutrients to the diet. Coastal meadows, fed by the brackish water of the Baltic Sea and free of anthropogenic pollution, are a good habitat to collect wild greens from.
