Activity of antioxidative defense enzymes in the blood of patients with liver echinococcosis

Background/Aim. Chronic echinococcocal disease is the parasite human disease caused by the penetration of larval (asexual) stages of the canine tapeworm (Echinococcus granulosus) in the liver of humans. After the penetration of the parasite, the host organism react by activating complement- depending immune response. The aim of this study was to elucidate the influence of larval form of Echinococcus granulosus in the liver on the activity of antioxidative defense enzymes in the blood of patients before and after the surgical intervention. Methods. We investigated the activity of antioxidative defense enzymes: copper/zinc containing superoxide dismutase (CuZn SOD), catalase (CAT), glutathione peroxidase (GSH-Px), glutathione reductase (GR) and glutathione-S-transferase (GST) in the blood of patients before and after the surgical intervention in respect to the controls, clinically healthy persons. Results. Our results showed that the activity of the GSH-Px was significantly decreased in the plasma of the patients with echinocococal disease before the surgery in respect to the controls. The activity of GST was significantly higher in the blood of the patients after the surgery in comparison to the controls. Conclusion. Chronic liver echinoccocal disease caused significant changes of some antioxidative defense enzymes, first of all Se-dependent enzyme GSH-Px, which could be a suitabile biomarker in the biochemical evaluation of the disease. This work represents a first comprehensive study of the activity of antioxidative defense enzymes in cronic liver echinococcocosis in the patients before and after the surgical intervention in respect to the clinically healthy persons

Održiva poljoprivreda - značaj adaptacije agrotehničkih mera u proizvodnji ozime pšenice

The objectives of this study were to examine influence conventional vs low-input technology on some important soil physical properties, weed control and grain yield of winter wheat. The main conclusion that can be drawn from this result is that the significantly bulk density has been reached in NT system. The implication of the results first figure can be seen in two next soil physical properties total porosity and air-filled porosity were significantly lower compared to CT and MT system, as a consequence of higher bulk density. The significantly higher the total number of weeds have been recorded, under NT what is expected tendency and it was especially to perennial weeds. Conventional tillage had better effect in weed control than both of conservation tillage systems had. Through this results we can see that low input cultivars yielded better than high input cultivars. The low-input cultivars out yielded than high-input cultivars. Alternative small grains (Tr. aestivum ssp compactum, Tr, durum and Tr. Spelta) gives lower grain yield compared with commercial cultivar NS-40S.Održiva poljoprivreda je kompleks pronalaženja novih puteva praćen brojnim rizicima. Tu su rizici koji mogu biti praćeni smanjenjem prinosa i brojnim nepoznanicama u zaštiti bilja od bolesti i štetočina, ali i nekim drugim. Prelazak sa konvencionalnih sistema gajenja na racionalne zahteva brojne promene u tehnologiji gajenja. Tehnologije nižih ulaganja u proizvodnji ozime pšenice, uopšteno gledajući, zahtevaju adaptaciju najvažnijih mera i sastoje se od: redukovanih sistema obrade zemljišta, nižih normi đubrenja mineralnim đubrivima, upotrebe mikrobioloških đubriva, veće diversifikacije useva u plodoredu, itd. Racionalne tehnologije gajenja u proizvodnji ozime pšenice mogu značajno doprineti smanjenju zemljišne erozije, značajnom smanjenju troškova, odnosno većoj ekonomskoj efikasnosti, i to bez većeg smanjenja prinosa. Redukcije u primeni agrotehničkih mera mogu biti izvor stresa (mehanički, suša). Zato ovu činjenicu moraju imati u vidu oplemenjivači bilja koji će stvarati sorte koje bi u novostvorenim uslovima reagovale većom efikasnošću. Nove tehnologije podrazumevaju veću fleksibilnost u primeni pojedinih agrotehničkih mera (obrade zemljišta, đubrenja, zaštite od bolesti, štetočina i korova, plodoreda) sa pažljivo odabranim sortama za te uslove. Cilj ovog rada je da ukaže na značaj kreiranja održivih tehnologija gajenja ozime pšenice i njihov uticaj na fizičke osobine zemljišta, kontrolu korova i prinos

Aplinkos įtaka duoninių (Triticum aestivum L.) ir kietųjų (Triticum durum Desf.) kviečių albuminų kiekiui

Albumins or water soluble proteins (wsp) in wheat are important as nutrients containing high content of essential amino acids such as lysine, tryptophan, methionine, and also asparagine, glutamine, arginine, and proline in comparison to storage proteins-glutenins and gliadins. Fifteen bread wheat (Triticum aestivum L.) and 15 durum wheat (Triticum durum Desf.) genotypes were evaluated across six different environments for two years to determine the content of albumins in grains. The purpose of this research was to determine the variability of the albumins content of the tested bread wheat and durum wheat genotypes, effects of environment, genotype and their interaction (GEI) on the trait of interest, heritability in a broad sense, stability, and also to interpret GEI by climatic factors modelling. The statistical procedure included analysis of variance, sites regression and factorial regression. The mean content of albumins was 20.23 g kg-1 in bread wheat and 23.12 g kg-1 in durum wheat. Environment followed by GEI was the most important in determining albumins content. The heritability in a broad sense was low, i.e. 31.3% for bread wheat and only 2.4% for durum wheat. GEI for the albumins content was explained with the efficacy of 94.7% and 94.2% of sum of squares, for bread wheat and durum wheat, respectively, by the following models: mean temperature in May, winter moisture reserves, minimum temperature in April and March for bread wheat; and precipitation sum in April, sunshine hours sum in March, maximum temperature in May, and winter moisture reserves for durum wheat. The simultaneous selection for high albumins content and good stability proved to be possible for bread wheat genotypes, but less for durum wheat genotypes due to unsatisfactory stability

Genotype x Environment interaction for antioxidants and phytic acid contents in bread and durum wheat as influenced by climate

Antioxidants prevent oxidative stress and exert positive health effects. However, phytic acid among them decreases micronutrients absorption, representing also antinutrient to human and non-ruminant animals. Fifteen bread wheat (Triticum aestivum L.) and 15 durum wheat (Triticum durum Desf.) genotypes were evaluated across six environments to determine contents of phytic acid (PA), inorganic P (Pi), total yellow pigment, total soluble phenolic compounds, free protein sulfhydryl groups (PSH), and also phytic acid P/P-i (P-p/P-i). The objective of this study was to quantify, for each trait the effects of environment, genotype, and their interaction; and the influence of climatic factors on the Genotype x Environment interaction (GEI) by the use of the factorial regression. GEI (P lt 0.001) prevailed as source of variation over genotype (P lt 0.001) in determining PA content in bread and durum wheat (44.3% and 34.7% of sum of squares-SS, respectively), PSH content in bread and durum wheat (27% and 28.4% of SS, respectively) and total soluble phenolic compounds content in durum wheat (35.5% of SS). The major contribution to the GEI represented climatic variables during stages of stem elongation for PA and phenolic compounds, and also flowering, fertilization, grain formation and grain filling for PSH. Total yellow pigment and Pi contents in bread and durum wheat were predominantly determined by genotype (P lt 0.001). Models of climatic variables proved to be efficient in the explanation of more than 92% of the SS of GEI for PA and antioxidants contents

The application of triticale variety Odyssey as the substitute for malt in wort production

The objective of this work was to investigate the possibility of triticale application as the partial substitute for malt in wort production. For wort production, two series of experiments were performed in which triticale variety Odyssey, from experimental fields, Rimski Šančevi location (Serbia), was used as the substitute for barley malt in grist with and without the addition of commercial enzyme Ultraflo Max (Novozymes, Denmark). Triticale was added in each of the carried series of experiments as the substitute for malt: 0, 10, 20, 30, 40, 50, 60, 70 and 80% in grist. Experiments were carried out on laboratory scale by the application of infusion procedure for wort production. Regarding extract content, triticale variety Odyssey could be used as the substitute for malt up to 60% without the addition of commercial enzyme Ultraflo Max. With the addition of this enzyme triticale variety Odyssey could be used as a substitute for malt up to 80%, regarding the extract content. With the increase in the content of triticale in the grist, viscosity increased. The addition of commercial enzyme Ultraflo Max significantly reduced wort viscosity. The obtained results indicate that worts produced with the addition of triticale variety Odyssey to grist yielded good analytical quality parameters

Determination of polymorphism of microsatellite primers in hexaploid wheat

The objective of this paper was to examine the functionality of two microsatellite primers as their polymorphism levels were determined for select Novi Sad wheat genotypes. Chosen as representatives of Gater-sleben wheat microsatellites (GWM) were two sets of microsatellite primers, GWM 165 and GWM539, which had been described according to RODER et al. (1998a; 1998b). Twenty five wheat genotypes from the World Collection of the Institute of Field and Vegetable Crops in Novi Sad were used in the study. Genomic DNA was isolated from the plant materials using a modification of the PLASCHKE et al. (1995) method. PCR amplification of the desired fragments was carried out in a volume of 30 ul (Eppendorf thermocycler) according to RODER et al. (1998b). The PAGE conditions were implemented according to GALOV1Ć et al. (2004). The GWM539 set, with six different alleles, showed a higher level of polymorphism than GWM165, in which three different alleles were detected for the locus concerned

The influence of technological parameters on malt quality produced from different triticale varieties

The analysis of eight different triticale varieties, from selective experiments, crop 2007, from Rimski Šančevi (Serbia) location was performed. On the basis of results obtained from triticale and produced triticale malt analysis as well as during micromalting, technological quality of investigated triticale varieties was evaluated. The aim of the work was to determine if the gibberellic acid added during the germination phase had a positive influence on the degradation of triticale grain during micromalting. Based on the obtained results it was concluded that triticale variety has the most important influence on the quality of produced triticale malt
