Dietary buckwheat enhances sirtuin1 without calorie restriction / S. Pande, R. Ranjan, A. N. Shuvaev [et al.] // J. Cereal Sci. - 2020. - Vol. 94. - Ст. 103004, DOI 10.1016/j.jcs.2020.103004 . - ISSN 0733-5210

Calorie restriction -- Dietary buckwheat -- Male wistar rats -- SIRT1 expression
Аннотация: In the present investigation, the role of dietary intervention in male Wistar rats (n = 8, 3 groups) was studied to observe absolute sirtuin 1 (SIRT1) levels (expressed as ng mg?1 total protein) in serum, stomach, liver, and kidney. Dietary buckwheat at 30% (w/w) level of incorporation in the standard diet (Buckwheat Enriched Diet, BED) improved SIRT1 with values 0.933 ± 0.05, 210 ± 7, 63.26 ± 4, and 69.89 ± 3 in serum, stomach, liver, and kidney respectively when compared to the respective control values of 0.536 ± 0.03, 156 ± 23.3, 31.07 ± 2 and 47.11 ± 4. Moreover, BED though isocaloric to CR diet, led to weight gain (g) by 63.11 ± 3.8, ca. 10%, and 40% higher than control (56.27 ± 5.6) and CR (45.05 ± 4.1) diet groups. A marked rise in Feed Efficiency Ratio (FER) by ca. 37% while a 30% decrease in Feed Conversion Ratio (FCR) was observed for the BED group which supports unexpected weight gain in rats post-dietary intervention. The results justify the superior nutritional profile of buckwheat laden with essential nutrients, essential proteins, and bioactives. In contrast, Calorie Restriction (CR) resulted in a decline of the total protein content in circulation by 19%, while reduction of total protein in stomach, liver, and kidney was estimated to be 95%, 35.2%, and 27% respectively though SIRT1 values were comparatively the highest in all the samples studied. A 30-fold enhancement of SIRT1 in stomach post CR is presumed to counter enhanced stress in gastric tissues. Therefore, mild to moderate expression of SIRT1 may confer beneficial effects such as delayed aging and stress resistance but exceedingly high SIRT1 may evoke increased oxidative stress. © 2020 Elsevier Ltd

Surface wettability and energy effects on the biological performance of poly-3-hydroxybutyrate films treated with RF plasma / D. S. Syromotina [et al.] // Mater. Sci. Eng. C. - 2016. - Vol. 62. - P450-457, DOI 10.1016/j.msec.2016.01.075 . - ISSN 0928-4931

Аннотация: The surface properties of poly-3-hydroxybutyrate (P3HB) membranes were modified using oxygen and an ammonia radio-frequency (RF, 13.56 MHz) plasma. The plasma treatment procedures used in the study only affected the surface properties, including surface topography, without inducing any significant changes in the crystalline structure of the polymer, with the exception being a power level of 250 W. The wettability of the modified P3HB surfaces was significantly increased after the plasma treatment, irrespective of the treatment procedure used. It was revealed that both surface chemistry and surface roughness changes caused by the plasma treatment affected surface wettability. A treatment-induced surface aging effect was observed and resulted in an increase in the water contact angle and a decrease in the surface free energy. However, the difference in the water contact angle between the polymers that had been treated for 4 weeks and the untreated polymer surfaces was still significant. A dependence between cell adhesion and proliferation and the polar component of the surface energy was revealed. The increase in the polar component after the ammonia plasma modification significantly increased cell adhesion and proliferation on biodegradable polymer surfaces compared to the untreated P3HB and the P3HB modified using an oxygen plasma. © 2016 Elsevier B.V.

Efficiency of transfer of essential polyunsaturated fatty acids versus organic carbon from producers to consumers in a eutrophic reservoir / M. I. Gladyshev [et al.] // Oecologia. - 2011. - Vol. 165, Is. 2. - P521-531, DOI 10.1007/s00442-010-1843-6 . - ISSN 0029-8549

Аннотация: One of the central paradigms of ecology is that only about 10% of organic carbon production of one trophic level is incorporated into new biomass of organisms of the next trophic level. Many of energy-yielding compounds of carbon are designated as 'essential', because they cannot be synthesized de novo by consumers and must be obtained with food, while they play important structural and regulatory functions. The question arises: are the essential compounds transferred through trophic chains with the same efficiency as bulk carbon? To answer this question, we measured gross primary production of phytoplankton and secondary production of zooplankton and content of organic carbon and essential polyunsaturated fatty acids of ?-3 family with 18-22 carbon atoms (PUFA) in the biomass of phytoplankton and zooplankton in a small eutrophic reservoir during two summers. Transfer efficiency between the two trophic levels, phytoplankton (producers) and zooplankton (consumers), was calculated as ratio of the primary production versus the secondary (zooplankton) production for both carbon and PUFA. We found that the essential PUFA were transferred from the producers to the primary consumers with about twice higher efficiency than bulk carbon. In contrast, polyunsaturated fatty acids with 16 carbon atoms, which are synthesized exclusively by phytoplankton, but are not essential for animals, had significantly lower transfer efficiency than both bulk carbon, and essential PUFA. Thus, the trophic pyramid concept, which implicitly implies that all the energy-yielding compounds of carbon are transferred from one trophic level to the next with the same efficiency of about on average 10%, should be specified for different carbon compounds.

Аннотация: Bioregenerative life-support systems (BLSS) are studied for developing the technology for a future biological life-support system for long-term manned space missions. Ways to utilize human liquid and solid wastes to increase the closure degree of BLSS were investigated. First, urine and faeces underwent oxidation by Kudenko's physicochemical method. The products were then used for root nutrition of wheat grown by the soil-like substrate culture method. Two means of eliminating sodium chloride, introduced into the irrigation solution together with the products of urine oxidation, were investigated. The first was based on routine electrodialysis of irrigation water at the end of wheat vegetation. Dialysis eliminated about 50% of Na from the solution. This desalinization was performed for nine vegetations. The second method was new: after wheat cultivation, the irrigation solution and the solution obtained by washing the substrate containing mineral elements not absorbed by the plants were used to grow salt-tolerant Salicornia europaea L. plants (saltwort). The above-ground biomass of this plant can be used as a food, and roots can be added to the soil-like substrate. Four consecutive wheat and Salicornia vegetations were cultivated. As a result of this wheat and Salicornia cultivation process, the soil-like substrate salinization by NaCl were considerably decreased. В© 2008 Humana Press.

Аннотация: The usage of chlorophyll fluorescence induction (CFI) for estimating various types of plant resistance (primary, general, initial, adaptive) to stress factors is reviewed. The necessity of ontogenetic approach (considering the age-specific properties of the photosynthetic apparatus) in determining general and adaptive resistance of plants to prolonged action of stress factors by the CFI method is argued. In the plant Cucumbis sativus L., the possibility is shown of using age-specific qualitative and quantitative traits of leaf CFI (changes in the shape of chlorophyll fluorescence induction curves and in the dynamics of CFI parameters in the course of leaf ontogeny) for comparative study of differences between fully active and stressed plants. Possible criteria are suggested for estimating the effect of outer stress factors by the presence or absence of a steady-state phase in the dynamics of CFI parameters during leaf ontogeny. It is also suggested to use the duration of the steady-state phase following the termination of leaf growth (estimated by the dynamics of the slow phase of CFI as the ratio of fluorescence intensity at the peak P and the steady-state fluorescence intensity, FP/FS, or as the viability index Rfd) and the variability of CFI parameters during this period as qualitative estimates of plant resistance to prolonged action of stress factors.

Аннотация: Populations of Escherichia coli Z905/pPHL7, a transgenic microorganism, were heterogenic in the expression of plasmid genes when adapting to the conditions of water microcosms of various mineralization levels and structure of microbial community. This TM has formed two subpopulations (ampicillin- resistant and ampicillin-sensitive) in every microcosm. Irrespective of mineralization level of a microcosm, when E. coli Z905/pPHL7 alone was introduced, the ampicillin-resistant subpopulation prevailed, while introduction of the TM together with indigenous bacteria led to the dominance of the ampicillin-sensitive subpopulation. A high level of lux gene expression maintained longer in the freshwater microcosms than in sterile saline lake water microcosms. A horizontal gene transfer has been revealed between the jointly introduced TM and Micrococcus sp. 9/pSH1 in microcosms with the Lake Shira sterile water. В© 2005 COSPAR. Published by Elsevier Ltd.

Biological and physicochemical methods for utilization of plant wastes and human exometabolites for increasing internal cycling and closure of life support systems / I. G.

Аннотация: Wheat was cultivated on soil-like substrate (SLS) produced by the action of worms and microflora from the inedible biomass of wheat. After the growth of the wheat crop, the inedible biomass was restored in SLS and exposed to decomposition ("biological" combustion) and its mineral compounds were assimilated by plants. Grain was returned to the SLS in the amount equivalent to human solid waste produced by consumption of the grain. Human wastes (urine and feces) after physicochemical processing turned into mineralized form (mineralized urine and mineralized feces) and entered the plants' nutrient solution amounts equal to average daily production. Periodically (once every 60-70 days) the nutrient solution was partly (up to 50%) desalinated by electrodialysis. Due to this NaCl concentration in the nutrient solution was sustained at a fixed level of about 0.26%. The salt concentrate obtained could be used in the human nutrition through NaCl extraction and the residuary elements were returned through the mineralized human liquid wastes into matter turnover. The control wheat cultivation was carried out on peat with use of the Knop nutrient solution. Serial cultivation of several wheat vegetations within 280 days was conducted during the experiment. Grain output varied and yield/harvest depended, in large part, upon the amount of inedible biomass returned to SLS and the speed of its decomposition. After achieving a stationary regime, (when the quantity of wheat inedible biomass utilized during vegetation in SLS is equal to the quantity of biomass introduced into SLS before vegetation) grain harvest in comparison with the control was at most 30% less, and in some cases was comparable to the control harvest values. The investigations carried out on the wheat example demonstrated in principle the possibility of long-term functioning of the LSS photosynthesizing link based on optimizations of biological and physicochemical methods of utilization of the human and plants wastes. The possibilities for the use of these technologies for the creation integrated biological-physicochemical LSS with high closure degree of internal matter turnover are discussed in this paper.

Аннотация: The physiological, biochemical, genetic, and cultural characteristics of the glucose-utilizing mutant strain Ralstonia eutropha B8562 were investigated in comparison with the parent strain R. eutropha B5786. The morphological, cultural, and biochemical characteristics of strain R. eutropha B8562 were similar to those of strain R. eutropha B5786. Genetic analysis revealed differences between the 16S rRNA gene sequences of these strains. The growth characteristics of the mutant using glucose as the sole carbon and energy source were comparable with those of the parent strain grown on fructose. Strain B8562 was characterized by high yields of polyhydroxyalkanoate (PHA) from different carbon sources (CO 2, fructose, and glucose). In batch culture with glucose under nitrogen limitation, PHA accumulation reached 90% of dry weight. In PHA, ?-hydroxybutyrate was predominant (over 99 mol %); ?-hydroxyvalerate (0.25-0.72 mol %) and ?-hydroxyhexanoate (0.008-1.5 mol %) were present as minor components. The strain has prospects as a PHA producer on glucose-containing media.

Material balance and diet in bioregenerative life support systems: Connection with coefficient of closure / N. S. Manukovsky [et al.] // Advances in Space Research. - 2005. - Vol. 35, Is. 9 SPEC. ISS. - P1563-1569, DOI 10.1016/j.asr.2005.01.002 . - ISSN 0273-1177

Аннотация: Bioregenerative life support systems (BLSS) with different coefficients of closure are considered. The 66.2% coefficient of closure achieved in "BIOS-3" facility experiments has been taken as a base value. The increase in coefficient of closure up to 72.6-93.0% is planned due to use of soil-like substrate (SLS) and concentrating of urine. Food values were estimated both in a base variant ("BIOS-3"), and with increases in the coefficient of closure. It is shown that food requirements will be more fully satisfied by internal crop production with an increase in the coefficient of closure of the BLSS. Changes of massflow rates on an 'input-output' and inside BLSS are considered. Equations of synthesis and degradation of organic substances in BLSS were examined using a stoichiometric model. The paper shows that at incomplete closure of BLSS containing SLS there is a problem of nitrogen balancing. To compensate for the removal of nitrogen from the system in urine and feces, it is necessary to introduce food and a nitrogen-containing additive. В© 2005 COSPAR. Published by Elsevier Ltd.

Developing the control criterion for a continuous culture of microorganisms / V. V. Adamovich, D. Yu. Rogozin, A. G. Degermendzhi // Mikrobiologiya. - 2005. - Vol. 74, Is. 1. - С. 5-16 . - ISSN 0026-3656

Аннотация: A short survey and critical analysis of previously proposed criteria for growth control of populations of microorganisms in the chemostat are presented. Based on the analysis of a mathematical model of the steady-state of a microbial population in the chemostat, an adequate control criterion is suggested, along with a method to identify the corresponding regulating factors. The new control criterion is expressed as a product of the factor transformation coefficient and the biomass sensitivity coefficient (SC) with respect to the change of the factor at the chemostat inlet (referred to in the sequel as the biomass SC). The control criterion determines the strength of the control exerted by this or that factor. The method of determination of the regulating factors consists in experimental determination of the real SCs for factors and the biomass and in calculating on this basis the corresponding ideal SCs for constant factor transformation coefficients. The ideal SCs are shown to add up to an integer value, a constraint that we call "quantization" relationships. Such relationships are used to test the completeness of the drawn list of control factors. The proposed method was applied to our own and literature data.
