Investigation of the Influence of Flaxseed Meal on the Biochemical Processes of the Wheat Test

One of the well-known tasks in the organization of nutrition is the development of new bakery products with high nutritional and biological value and wellness properties.Linen meal is an important source of dietary fiber, high protein, unsaturated fatty acids, minerals and vitaminsThe purpose of the research was to determine the effect of this meal on the depth of the processes occurring in the dough during kneading and maturing.A linseed meal LLC «Zhytomyrbioproduct» (Ukraine) with a certain chemical composition was used in the research.The research was conducted to study the effect of flaxseed meal on the kinetics of sugars in the dough during its maturation. The study was performed using an iodometric method, based on the determination of the amount of oxidized copper before and after recovery of the alkaline copper solution with sugar.It has been established, that the addition of flax seed meal to the dough reduces the amount of sugars, formed during the maturation of the dough, which adversely affects the activity of the dough microflora. This is confirmed by the lower consumption of sugars for fermentation.The viscosity of water-flour slurry with a flaxseed meal has been investigated. The starch grains are infinitely swollen in the process of increasing temperature of the slurry in the amylograph, and a starch paste is formed, the viscosity of which increases with temperature. At the same time, under the action of flour enzymes, there is a decrease in viscosity due to the hydrolysis of starch.The results of the researches testify about the effectiveness of the offered methods of studying the rules and depth of processes in the dough with a meal of flax seed during its preparation and maturing, which will allow to increase the yield of the dough and the output of high quality finished products

Aldehyde Dehidrogenase Level and Fatty Acid Ethyl Ester as Biochemical Markers Persist Longer Than Ethanol in Wistar Rats After Chronic Alcohol Consumption

Alcohol consumption in human has increased from year to year in Indonesia and more recently, anincreasing number of cases of alcohol intoxication, alcoholic liver disease, and death were observed.The purpose of this experimental study was to examine the significance of two known biochemicalmarkers of alcohol given by mouth in the Wistar rats. The study design used was the “Truerandomized experimental post test only control group design". The rats were randomly distributedaccording to the experimental design and were treated daily for six weeks (chronic intake) with 5%and 20% alcohol. This study used 15 rats with 5 rats for treatment group treated with 5% alcohol, 5rats for treatment group treated with 20% alcohol, and 5 rats as control group treated with distilledwater. The biochemical markers were aldehyde dehydrogenase (ALDH) and Fatty Acid Ethyl Esters(FAEE). ALDH and FAEE were two biochemical markers of ethanol which are sensitive and specificfor alcohol consumption. The study was conducted in two phases. Initially, rats were treated orallyeveryday for six weeks with 5% and 20% alcohol, and then the blood level of ethanol, ALDH andFAEE were measured. Blood samples were collected at 6 and 24 hours after the last oral intake ofchronic alcohol administration. Qualitative analysis was carried out to detect the presence of ethanol,ALDH, and FAEE in the treatment groups and quantitative analysis to determine their levels in theblood of Wistar rats. Statistical analysis of ALDH was done by using parametric test and the presenceof FAEE persisting longer than ethanol by non-parametric test. The results showed that ALDHpersisted and increased significantly following chronic consumption of alcohol in the rats. Similarly,FAEEs persisted longer than ethanol after alcohol intake. After six hours, the ALDH level increasedby 108.14% in the rat treated chronically with 5% alcohol and by 85.07% in rat treated with 20%alcohol. After 24 hours, FAEE also persisted longer in the blood than ethanol following treatmentwith alcohol 5%. ALDH levels increased by 83.11% after chronic treatment with 5% alcohol and by112.05% in the rats treated with 20% alcohol. In the blood collected 24 hours after the last treatmentwith 5% alcohol, ALDH increased by 95.11% and by 86.79% in the rats treated with 20% alcohol.FAEE persisted longer than ethanol in the blood following administration of 5 % and 20% alcoholboth at 24 hours following chronic treatment. The longer persisting ALDH and FAEE were new andgood biochemical blood markers for chronic alcohol consumption in the Wistar rats

Enhancement of microalgae anaerobic digestion by thermo-alkaline pretreatment with lime (CaO)

The aim of this study was to evaluate for the first time the effect of a thermo-alkaline pretreatment with lime (CaO) on microalgae anaerobic digestion. The pretreatment was carried out by adding different CaO doses (4 and 10%) at different temperatures (room temperature (25 °C), 55 and 72 °C). The exposure time was 4 days for pretreatments at 25 °C, and 24 h for pretreatments at 55 and 72 °C. Following, a biochemical methane potential test was conducted with pretreated and untreated microalgae. According to the results, the pretreatment enhanced proteins solubilisation by 32.4% and carbohydrates solubilisation by 31.4% with the highest lime dose and temperature (10% CaO and 72 °C). Furthermore, anaerobic digestion kinetics were improved in all cases (from 0.08 to 0.14 day- 1 for untreated and pretreated microalgae, respectively). The maximum biochemical methane potential increase (25%) was achieved with 10% CaO at 72 °C, in accordance with the highest biomass solubilisation. Thus, lime pretreatment appears as a potential strategy to improve microalgae anaerobic digestion.Peer ReviewedPostprint (author's final draft

Pasireotide for the Medical Management of Feline Hypersomatotropism

BACKGROUND: Feline hypersomatotropism (HST) is a cause of diabetes mellitus in cats. Pasireotide is a novel multireceptor ligand somatostatin analog that improves biochemical control of humans with HST. HYPOTHESIS/OBJECTIVES: Pasireotide improves biochemical control of HST and diabetes mellitus in cats. ANIMALS: Hypersomatotropism was diagnosed in diabetic cats with serum insulin‐like growth factor‐1 (IGF‐1) concentration >1,000 ng/mL by radioimmunoassay and pituitary enlargement. METHODS: Insulin‐like growth factor 1 was measured and glycemic control assessed using a 12‐hour blood glucose curve on days 1 and 5. On days 2, 3, and 4, cats received 0.03 mg/kg pasireotide SC q12h. IGF‐1, insulin dose, and estimated insulin sensitivity (product of the area under the blood glucose curve [BGC] and insulin dose) were compared pre‐ and post treatment. Paired t‐tests or Wilcoxon signed rank tests were employed for comparison where appropriate; a linear mixed model was created to compare BGC results. RESULTS: Insulin‐like growth factor 1 decreased in all 12 cats that completed the study (median [range] day 1: 2,000 ng/mL [1,051–2,000] and day 5: 1,105 ng/mL [380–1,727], P = .002, Wilcoxon signed rank test). Insulin dose was lower on day 5 than on day 1 (mean reduction 1.3 [0–2.7] units/kg/injection, P = .003, paired t‐test). The product of insulin dose and area under the BGC was lower on day 5 than day 1 (difference of means: 1,912; SD, 1523; u × mg/dL × hours, P = .001; paired t‐test). No clinically relevant adverse effects were encountered. CONCLUSIONS: Short‐acting pasireotide rapidly decreased IGF‐1 in cats with HST and insulin‐dependent diabetes. The decrease in IGF‐1 was associated with increased insulin sensitivity

The potential of Symbiont Ba cteria in Melo melo Gastropod found in Pekalongan Waters as a source of MDR antibacterial active compound

The increasing resistance of many pathogenic microorganisms against antibiotics compounds creates an alarming issue in medical world. This concern has created research opportunities in new antibiotics compounds as alternative options. The gastropod Melo melo is a species whose main diet consists of other smaller gastropods. However, Melo-melo does not have any self-defense mechanism save for its thin shell. To protect itself from various pathogenic bacteria existing in its food, Melo melo produces secondary metabolites, which are suspected to contain bioactive compounds with antibacterial properties. This fact puts Melo melo as a marine biota with potential as a source of new antibacterial compounds. This research aims to discover the potency of symbiont bacteria in the gastropod Melo melo with capabilities in producing Multi-drug resistant (MDR) antibacterial compounds. Samples of Melo melo are collected from the vicinity of Pekalongan waters, Central Java, Indonesia. This research begins with the isolation of symbiont bacteria, screening of symbiont bacteria with potency in MDR antibacterial activities, antibacterial test, and isolation of MDR clinical pathogenic bacteria. These protocols are then followed by antibacterial sensitivity test, and identification of bacterial species active against MDR by biochemical test and molecular analysis. Molecular analyses are carried out sequentially by DNA extraction, DNA amplification by PCR, and DNA sequencing. Results of 16S rDNA are analyzed using Genetix program and then followed by sequence analysis of the 16S rDNA. In this research, 11 bacteria in Melo melo are isolated and there are 4 isolates which show antibacterial activities against MDR bacteria from Pseudomonas sp. and Enterobacter sp species. Molecular analysis of the most active isolates identifies that isolate PM 26 matches in characteristics with Brevibacterium celere strain KMM 3637 with 89% homology match. On the other hand, biochemical test shows that isolate PM 26 is identical with Bacillus sp. This research concludes that symbiont bacteria found in Melo melo possess antibacterial activities against bacteria of MDR strain

A passivity-based stability criterion for a class of interconnected systems and applications to biochemical reaction networks

This paper presents a stability test for a class of interconnected nonlinear systems motivated by biochemical reaction networks. One of the main results determines global asymptotic stability of the network from the diagonal stability of a "dissipativity matrix" which incorporates information about the passivity properties of the subsystems, the interconnection structure of the network, and the signs of the interconnection terms. This stability test encompasses the "secant criterion" for cyclic networks presented in our previous paper, and extends it to a general interconnection structure represented by a graph. A second main result allows one to accommodate state products. This extension makes the new stability criterion applicable to a broader class of models, even in the case of cyclic systems. The new stability test is illustrated on a mitogen activated protein kinase (MAPK) cascade model, and on a branched interconnection structure motivated by metabolic networks. Finally, another result addresses the robustness of stability in the presence of diffusion terms in a compartmental system made out of identical systems.Comment: See http://www.math.rutgers.edu/~sontag/PUBDIR/index.html for related (p)reprint

Inoculum selection influences the biochemical methane potential of agro-industrial substrates

Obtaining a reliable estimation of the methane potential of organic waste streams in anaerobic digestion, for which a biochemical methane potential (BMP) test is often used, is of high importance. Standardization of this BMP test is required to ensure inter-laboratory repeatability and accuracy of the BMP results. Therefore, guidelines were set out; yet, these do not provide sufficient information concerning origin of and the microbial community in the test inoculum. Here, the specific contribution of the methanogenic community on the BMP test results was evaluated. The biomethane potential of four different substrates (molasses, bio-refinery waste, liquid manure and high-rate activated sludge) was determined by means of four different inocula from full-scale anaerobic digestion plants. A significant effect of the selected inoculum on the BMP result was observed for two out of four substrates. This inoculum effect could be attributed to the abundance of methanogens and a potential inhibiting effect in the inoculum itself, demonstrating the importance of inoculum selection for BMP testing. We recommend the application of granular sludge as an inoculum, because of its higher methanogenic abundance and activity, and protection from bulk solutions, compared with other inocula

Paenibacillus brasilensis sp nov., a novel nitrogen-fixing species isolated from the maize rhizosphere in Brazil

Sixteen nitrogen-fixing strains isolated from the rhizosphere of maize planted in Cerrado soil, Brazil, which showed morphological and biochemical characteristics similar to the gas-forming Paenibacillus spp., were phenotypically and genetically characterized. Their identification as members of the genus Paenibacillus was confirmed by using specific primers based on the 16S rRNA gene. SDS-PAGE of whole-cell proteins, API 50CH, morphological and biochemical tests, amplified rDNA-restriction analysis (ARDRA), DNA-relatedness analyses, denaturing-gradient gel electrophoresis (DGGE) and 16S rRNA gene sequence determinations were performed to characterize the novel isolates and to compare them to strains of other nitrogen-fixing Paenibacillus spp. Phenotypic analyses showed that the 16 strains were very homogeneous and shared a high level of relatedness with Paenibacillus polymyxa and Paenibacillus peoriae. However, none of the novel isolates was able to ferment glycerol (positive test for P. polymyxa), L-arabinose or D-xylose (positive tests for P. polymyxa and P. peoriae) or utilize succinate (positive test for P. peoriae). Genetic approaches also indicated a high level of similarity among the novel isolates and P. polymyxa and P. peoriae, but the novel strains clearly could not be assigned to either of these two recognized species. On the basis of the features presented in this study, the 16 novel isolates were considered to represent members of a novel species within the genus Paenibacillus, for which the name Paenibacillus brasilensis is proposed. The type strain is PB172(T) (=ATCC BAA-413(T)=DSM 14914(T)
