Pastas Quality Evaluation with Addition of Soy Okara [Szója okara hozzáadásával készült tészták minőségi analízise]
No full textIn this work we analysed the main properties of soy okara and prospects for its use as an additive for pasta enrichment. Pasta, which is a mass consumer product, was chosen as the object of enrichment. During research, the process of drying soy okara at different temperatures was carried out. Three prototypes were developed with the addition of dried soy okara in the amounts of 5%, 10%, or 15% by weight of the flour. Assessments of obtained prototypes were carried out in terms of organoleptic, physico-chemical indicators and their comparison with indicators of the control sample, as well as verification of compliance with requirements presented in regulatory documentation. Based on theoretical and experimental studies, a certain amount of soy okara was selected to be used as a raw material to increase the nutritional value of pasta. | Munkánk során a szója okara főbb tulajdonságait és a tésztadúsító adalékanyagként való felhasználásának lehetőségeit vizsgáltuk egy tömegfogyasztási termék, a tészta esetén. Kísérleteinkben a szója okarát különböző hőmérsékleten szárítottuk. Három prototípust fejlesztettünk ki, amelyekben a liszthez 5, 10 vagy 15 tömegszázalékban adtuk hozzá a szárított szója okarát. A kapott tészták értékelését az érzékszervi, fizikai-kémiai jellemzők és a kontrollminta tulajdonságaival való összehasonlításuk alapján, valamint a szabványban szereplő követelményeknek történő megfelelés ellenőrzésével végeztük el. Az elméleti és kísérleti eredmények alapján javasoljuk azt a hozzáadott szója okara mennyiséget, amely a tészták tápértékének növelésére használható
Effect of Natural Polysaccharide Matrix-Based Selenium Nanocomposites on Phytophthora cactorum and Rhizospheric Microorganisms
No full textWe studied the effects of new chemically synthesized selenium (Se) nanocomposites (NCs) based on natural polysaccharide matrices arabinogalactan (AG), starch (ST), and kappa-carrageenan (CAR) on the viability of phytopathogen Phytophthora cactorum, rhizospheric bacteria, and potato productivity in the field experiment. Using transmission electron microscopy (TEM), it was shown that the nanocomposites contained nanoparticles varying from 20 to 180 nm in size depending on the type of NC. All three investigated NCs had a fungicidal effect even at the lowest tested concentrations of 50 µg/mL for Se/AG NC (3 µg/mL Se), 35 µg/mL for Se/ST NC (0.5 µg/mL Se), and 39 µg/mL for Se/CAR NC (1.4 µg/mL Se), including concentration of 0.000625% Se (6.25 µg/mL) in the final suspension, which was used to study Se NC effects on bacterial growth of the three common rhizospheric bacteria Acinetobacter guillouiae, Rhodococcus erythropolis and Pseudomonas oryzihabitans isolated from the rhizosphere of plants growing in the Irkutsk Region, Russia. The AG-based Se NC (Se/AG NC) and CAR-based Se NC (Se/CAR NC) exhibited the greatest inhibition of fungal growth up to 60% (at 300 µg/mL) and 49% (at 234 µg/mL), respectively. The safe use of Se NCs against phytopathogens requires them to be environmentally friendly without negative effects on rhizospheric microorganisms. The same concentration of 0.000625% Se (6.25 µg/mL) in the final suspension of all three Se NCs (which corresponds to 105.57 µg/mL for Se/AG NC, 428.08 µg/mL for Se/ST NC and 170.30 µg/mL for Se/CAR NC) was used to study their effect on bacterial growth (bactericidal, bacteriostatic, and biofilm formation effects) of the three rhizospheric bacteria. Based on our earlier studies this concentration had an antibacterial effect against the phytopathogenic bacterium Clavibacter sepedonicus that causes diseases of potato ring rot, but did not negatively affect the viability of potato plants at this concentration. In this study, using this concentration no bacteriostatic and bactericidal activity of all three Se NCs were found against Rhodococcus erythropolis based on the optical density of a bacterial suspension, agar diffusion, and intensity of biofilm formation, but Se/CAR and Se/AG NCs inhibited the growth of Pseudomonas oryzihabitans. The cell growth was decrease by 15–30% during the entire observation period, but the stimulation of biofilm formation by this bacterium was observed for Se/CAR NC. Se/AG NC also had bacteriostatic and antibiofilm effects on the rhizospheric bacterium Acinetobacter guillouiae. There was a 2.5-fold decrease in bacterial growth and a 30% decrease in biofilm formation, but Se/CAR NC stimulated the growth of A. guillouiae. According to the results of the preliminary field test, an increase in potato productivity by an average of 30% was revealed after the pre-planting treatment of tubers by spraying them with Se/AG and Se/CAR NCs with the same concentration of Se of 0.000625% (6.25 µg/mL) in a final suspension. The obtained and previously published results on the positive effect of natural matrix-based Se NCs on plants open up prospects for further investigation of their effects on rhizosphere bacteria and resistance of cultivated plants to stress factors.Open-Access-Publikationsfonds 202

METABOLIC HEALTHY OBESITY, WHAT DO WE KNOW ABOUT IT?
No full textThe prevalence of obesity is growing all over the world. Obesity is an important risk factor for cardiovascular diseases, type 2 diabetes. However, not all obese patients have an unfavorable cardio-metabolic profile. Recently, much attention has been paid to the concept of «metabolically healthy obesity» (MHO). To date, there are no single criteria for identifying individuals with MHO, which makes it difficult to study this subgroup of patients and to conduct a comparative analysis of various studies. The article presents data of modern literature, including the definition, prevalence and mechanisms of MHO development, also discusses potentially protective factors involved in MHO development and the consequences of the therapeutic impact on MHO
Magnetic properties of inner magnetosphere during geomagnetic storms inferred from a tsy ganenko magnetic field model
No full textIn this paper we report some properties of inner magnetospheric structure inferred from the T01s code, one of the latest magnetospheric models by Tsyganenko. We have constructed three average storms representing moderate, strong, and severe intensity storms using 95 actual storms. The three storms are then modelled by the T01s code to examine differences in magnetic structure among them. We find that the magnetic structure of intense storms is strikingly different from the normal structure. First, when the storm intensity is large, the field lines anchored at dayside longitudinal sectors become warped tailward to align to the solar wind direction. This is particularly so for the field lines anchored at the longitudinal sectors from postnoon through dusk. Also while for the moderate storm the equatorial magnetic field near geosynchronous altitude is found to be weakest near midnight sector, this depression region expands into even late afternoon sector during the severe storm. Accordingly the field line curvature radius at the equator in the premidnight geosynchronous region becomes unusually small, reaching down to a value less than 500 km. We attribute this strong depression and the dawn-dusk asymmetry to the combined effect from the enhanced tail current and the westward expansion/rotation of the partial ring current

A feature of the microbiota of the colon in patients with different phenotypes of obesity (pilot study)
No full textPurpose: to study the microbiota of the colon in patients with various types of obesity and in healthy people.Materials and methods: 37 people were examined (average age 39.6 ± 4.2 years) for the period 2018 – 2019. Formed 3 clinical groups. I group (n = 11) — healthy people with normal body weight (control), II group (n = 13) — patients with metabolically healthy obesity (MHO), III group (n = 13) — with obesity and metabolic disorders. In all patients, the basic metabolic parameters were studied and a quantitative assessment of the state of colon microbiocenosis was performed.Results: compared to the formal-normative quantitative indicators, the examined fecal groups I, II and III showed unidirectional changes characterized by a decrease (p < 0.05) of Lactobacillus spp., Bifi dobacterium spp., B. thetaiotaomicron and an increase (p < 0.05 ) Enterobacter spp. / Citrobacter spp. Colon microbiota changes in groups II and III are characterized by the appearance of Proteus spp. and Klebsiella spp. (9.1 % and 8.3 % respectively). C. diffi cile (8.3 %) was detected in feces only in group III and the frequency of detection of banal E. coli was increased. Th e amount of F. prausnitzii was reduced (p < 0.05) in group III compared with group 1.Conclusion: the data obtained as a result of a pilot study indicate changes in the microbiota of the colon in people with diff erent phenotypes of obesity
