The article presents the results of determining the ability of enterococci extracted from traditional Carpathian cheese bryndza to produce biologically active substances, in particular, amino acids, B vitamins and cations (ammonium, potassium, sodium, magnesium, calcium). It was found that the studied strains of enterococci in different quantities synthesized both essential and essential amino acids. Thus, the essential amino acid lysine was found in the cultivation of strains of E. durans SB18, E. durans SB20, in particular, its concentration was significantly increased by 15.6 and 10.4 %, respectively (P < 0.05) compared to the control. A probable increase in the essential amino acid histidine by 20 and 53.3 % (P < 0.05) was detected in the cultivation of only E. faecium SB12 and E. durans SB18. In addition, it was found a probable increase in threonine synthesis by enterococci E. durans SB6 and E. durans SB18, respectively – 33.3 and 39.6 % (P < 0.05). The replacement amino acid serine was able to synthesize strains of E. faecium SB12, E. durans SB18 and E. durans SB20, while its concentration increased by 40.0 (P < 0.001), 30.0 and 35.0 %, respectively < 0.01), and strains of E. durans, SB6, and E. durans SB18 synthesized glycine, the concentration of which increased by – 10.2 and 16.2 %, respectively (P < 0.01). In addition, it was found that the studied strains in small quantities synthesized B vitamins, or not synthesized at all. In all experimental samples the most vitamin B1 was detected, its concentration increased from 8.5 to 10.0 times (P < 0.001). Riboflavin was synthesized by three strains of enterococci – E. durans SB6, E. durans SB18, E. durans SB20, so the concentration of vitamin B2 probably increased, respectively, 4.1, 2.0 and 2.0 times (P < 0.05). Enterococci E. durans SB6, E. faecium SB12, E. durans SB18 and E. durans SB20 synthesized in significant quantities only vitamin B3, in particular, its concentration probably increased by 1.5, 1.5 (P < 0.05), respectively, 1.5 (P < 0.01) and 1.6 (P < 0.001) times, and vitamin B5 was produced by E. faecium SB12, E. durans SB18 and E. durans SB20, the concentration of nicotinic acid increased, respectively, 2.9 (P < 0.05), 8.4 and 9.5 (P < 0.001) times. Analysis of the macroelement composition of the supernatant of enterococci showed that strains of E. durans, SB6, E. faecium SB12, E. durans SB18 and E. durans SB20 are able to produce only Calcium, in particular, found a probable increase, respectively, in 1.8, 2.4, 1.6 and 1.4 times (P < 0.05).

The paper discusses the organized nutrition of preschool children living in adverse environmental conditions, from the point of view of the actual provision of their physiological need for food and biologically active substances to save health. Various methods were used in the work to assess nutrition, health, as well as the vitamin and mineral supply of the body by a non- invasive method using the VITASTIQ-2 device. According to the results of the study difficulties were identified in providing children with a diverse healthy diet already at the stage of children’s nutrition. Also we revealed an imbalance in the food set, which leads to an increased content of sodium and simple carbohydrates, to an insufficient amount of essential amino acids and vitamin B1. The integral index of usefulness of the chemical composition for a daily diet is calculated by the author’s method. It is noted that due to the food that is not eaten by children in preschool educational institutions, they have an imbalance in the intake of biologically active substances, which reduces the protective and adaptive reserves of the child to adverse environmental factors. In order to correct diets, group and individual recommendations were proposed, as well as recommendations at the level of education departments and municipal administrations.

Plant Components

Medicinal plants and their combinations due to the wide range of biologically active substances can influence on various links of the pathogenetic mechanism of development of DM type 2 and its complications. One of such combinations is an antidiabetic herbal mixture (Urticae folia, Rosae fructus, Myrtilli folia, Menthae folia and Taraxaci radices) with established hypoglycaemic, hypolipidemic, antioxidant, hepatoprotective, pancreatoprotective activity in previous pharmacological studies in vivo and in vitro and defined phytochemical composition. Thus, the aim of this study was to identify and establish the content of amino acids in the plant components of antidiabetic herbal mixture. The amino acids were separated by GC-MS method with pre-column derivatization. The calibration curves of twenty CRS of amino acids were linear (R2 &gt; 0.98) over the range of 1–100 µg/mL, the LODs and the LOQs were in the range of 0.01–0.07 µg/mL and 0.02–0.20 µg/mL, respectively. The results of analysis showed that the predominant essential amino acid was L-proline in Taraxaci radices, Urticae folia, Rosae fructus and Menthae folia, its total content was 101.46 mg/g, 25.31 mg/g, 23.04 mg/g and 19.30 mg/g, respectively. In addition, it was established total content of essential amino acid – L-leucine that can stimulate insulin secretion in β-cells of the pancreas. Its total content was 58.51 mg/g in Taraxaci radices, 9.58 mg/g in Myrtilli folia, 4.68 mg/g in Rosae fructus, 2.99 mg/g in Urticae folia and 0.79 mg/g in Menthae folia. Chromatographic examination also revealed L-phenylalanine, an essential amino acid important for antidiabetic therapy that can increase insulin secretion, stimulate proliferation and neogenesis of β-cells of the pancreas and reduce insulin resistance. Its total content was 13.42 mg/g in Myrtilli folia, 2.23 mg/g in Rosae fructus, 1.478 mg/g in Urticae folia, 1.46 mg/g in Taraxaci radices and 0.52 mg/g in Menthae folia. This phytochemical study shows, which plant material forms the amino acid composition and content in the finished herbal mixture and due to which biologically active substances the antidiabetic activity of this phytocomposition is manifested.

Far beyond simply being 11 of the 20 amino acids needed for protein synthesis, non-essential amino acids play numerous important roles in tumor metabolism. These diverse functions include providing precursors for the biosynthesis of macromolecules, controlling redox status and antioxidant systems, and serving as substrates for post-translational and epigenetic modifications. This functional diversity has sparked great interest in targeting non-essential amino acid metabolism for cancer therapy and has motivated the development of several therapies that are either already used in the clinic or are currently in clinical trials. In this review, we will discuss the important roles that each of the 11 non-essential amino acids play in cancer, how their metabolic pathways are linked, and how researchers are working to overcome the unique challenges of targeting non-essential amino acid metabolism for cancer therapy.

The aim of the present paper is to critically review the details of the published nutrition intervention trials, with and without exercise, targeting sarcopenia. Sarcopenia is the loss of muscle mass, strength and/or performance with age. Since amino acids and energy are required for muscle synthesis it is possible that nutritional intake influences sarcopenia. Nutritional studies are challenging to carry out because of the complexity of modulating dietary intake. It is very difficult to change one nutrient without influencing many others, which means that many of the published studies are problematic to interpret. The studies included evaluate whole protein, essential amino acids and β-hydroxyl β-methylbutyrate (HMB). Whole-protein supplementation failed to show a consistent effect on muscle mass, strength or function. This can be explained by the variations in study design, composition of the protein supplement and the failure to monitor voluntary food intake, adherence and baseline nutritional status. Essential amino-acid supplements showed an inconsistent effect but there are only two trials that have significant differences in methodology and the supplement used. The HMB studies are suggestive of a beneficial effect on older adults, but larger well-controlled studies are required that measure outcomes relevant to sarcopenia, ideally in sarcopenic populations. The issues of timing and distribution of protein intake, and increased splanchnic amino-acid sequestration are discussed, and recommendations for future trials are made.

1. Nitrogen balance was studied in growing male SPF-rats fed on diets in which each essential amino acid was varied from zero to about 120% of optimum requirement. From the balance results, optimum and maintenance requirements were estimated as well as the efficiency of utilization of amino acids for growth and growth + maintenance.2. N balance increased with increasing dietary level of the deficient amino acid; the response gradually diminished as the content of the amino acid approached optimum. At zero level of intake, negative N balance was found for all amino acids except histidine. The highest loss of body N was found in the sulphur-amino-acid-free diet and the lowest one in the lysine-free diet.3. Maximal utilization of essential amino acids for growth was found at dietary levels corresponding to 30–60% of optimum requirement and ranged from about 0.65 to 0.85 except for S amino acids and histidine. The utilization of S amino acids was about 0.55 while that of histidine exceeded 1.0. The utilization of amino acids for growth-tmaintenance was maximal at the lowest levels of intake and gradually decreased as the dietary concentration of the limiting amino acid increased. At dietary levels near optimum the utilization was about 06–07, except for S amino acids where the utilization was less than 0.5.

Phloem Sap

Animals generally require a dietary supply of various nutrients (vitamins, essential amino acids, etc.) because their biosynthetic capabilities are limited. The capacity of aphids to use plant phloem sap, with low essential amino acid content, has been attributed to their symbiotic bacteria, Buchnera aphidicola , which can synthesize these nutrients; but this has not been demonstrated empirically. We demonstrate here that phloem sap obtained from the severed stylets of pea aphids Acyrthosiphon pisum feeding on Vicia faba plants generally provided inadequate amounts of at least one essential amino acid to support aphid growth. Complementary analyses using aphids reared on chemically defined diets with each amino acid individually omitted revealed that the capacity of the symbiotic bacterium B. aphidicola to synthesize essential amino acids exceeded the dietary deficit of all phloem amino acids except methionine. It is proposed that this shortfall of methionine was met by aphid usage of the non-protein amino acid 5-methylmethionine in the phloem sap. This study provides the first quantitative demonstration that bacterial symbiosis can meet the nutritional demand of plant-reared aphids. It shows how symbiosis with micro-organisms has enabled this group of animals to escape from the constraint of requiring a balanced dietary supply of amino acids.

AbstractThis experiment was conducted to test two different protein sources as alternatives to the commonly used fish meal (FM) in the diet of the European eel (Anguilla anguilla). Six experimental diets were tested in three replicated lots of European eels. All diets contained the same protein and energy content (ca, 300 g crude protein per kg dry matter and 18·5 MJ/kg, respectively) but differed in the nature of the protein source: FM was the only protein source in the control diet and was fully or partially (0–5: 0–5) replaced by meat meal (MM) or sunflower meal (SFM) in four other diets; a sixth diet included SFM as the only protein source but was supplemented with several essential amino acids. Food intake, fish growth and several indices of diet and protein utilization were measured. MM clearly was the poorest protein source while SFM could replace, at least 0·5 of the FM with no significant reduction in performance. In addition, the European eel was able to utilize the supplement of essential amino acids. The full-SFM diet was improved significantly when supplemented and results were not statistically different from the control FM-based diet. Overall, a good correlation was found between the results of each diet and the respective essential amino acid index, calculated using as reference the essential amino acid requirements previously defined for another eel species, Anguilla japonica. This index could be used as a reliable measure for an a priori evaluation of alternative protein sources to be included in commercial foods for eels.
