Application of Pediococcus acidilactici LUHS29 immobilized in apple pomace matrix for high value wheat-barley sourdough bread
2017
The aim of this study was to evaluate the potential use of Pediococcus acidilactici LUHS29 immobilized in apple pomace in case to apply in barley sourdough fermentation for functional bread production. The strain was phenotypically characterized by the growth and acidification rate, carbohydrate metabolism and resistance to acidic conditions. The effect of immobilized bacterial cells on antioxidant properties of barley sourdough and on the acrylamide content in wheat-barley bread was analyzed. The phenotypic and molecular testing indicates the P. acidilactici having a versatile carbohydrate metabolism and acid resistance, showing 42.7% of viable cells surviving after incubation at low pH as…
Antioxidant defense parameters as predictive biomarkers for fermentative capacity of active dried wine yeast.
2014
The production of active dried yeast (ADY) is a common practice in industry for the maintenance of yeast starters and as a means of long term storage. The process, however, causes multiple cell injuries, with oxidative damage being one of the most important stresses. Consequentially, dehydration tolerance is a highly appreciated property in yeast for ADY production. In this study we analyzed the cellular redox environment in three Saccharomyces cerevisiae wine strains, which show markedly different fermentative capacities after dehydration. To measure/quantify the effect of dehydration on the S. cerevisiae strains, we used: (i) fluorescent probes; (ii) antioxidant enzyme activities; (ii) in…
Enhanced In Situ Availability of Aphanizomenon Flos-Aquae Constituents Entrapped in Buccal Films for the Treatment of Oxidative Stress-Related Oral D…
2019
In recent years, the key role of oxidative stress in pathogenesis of oral diseases has been emphasized and the use of antioxidant agents has been encouraged. Aphanizomenon flos-aquae (AFA) is a unicellular blue-green alga with antioxidant and anti-inflammatory properties. The aim of this study was the formulation and characterization of mucoadhesive thin layer films loaded with AFA, finalized to the treatment of oxidative stress (OS)-related oral diseases. First, to enhance the bioavailability of AFA constituents, the raw food grade material was appropriately treated by a high frequency homogenization able to disrupt cell walls. Thus, Eudragit®
Antioxidant supplementation in diabetic retinopathy
2020
Conventional treatments for diabetic retinopathy (DR) include glycaemic control, laser photocoagulation, vitrectomy, intravitreal triamcinolone, and intravitreal antivascular endothelial growth factor agents. However, these strategies have not been proven capable of halting the progression of this disease in all cases. The mechanisms leading to DR are not fully understood, but there is a growing body of evidence showing that oxidative stress plays a pivotal role in the development of this diabetic complications. Indeed, it has been proposed that oxidative stress is the initial and maintaining event that triggers and provides feedback to the other pathophysiological pathways related to DR. T…
In vitro bioaccessibility, transepithelial transport and antioxidant activity of Urtica dioica L. phenolic compounds in nettle based food products
2016
Nettle (Urtica dioica L.) is a well-known plant with a wide historical background use of stems, roots and leaves. Nettle leaves are an excellent source of phenolic compounds, principally 3-caffeoylquinic acid (3-CQA), caffeoylmalic acid (CMA) and rutin. The aim of this work was to evaluate the bioaccessibility (BAC), the bioavailability (BAV) and the antioxidant activity of nettle phenolic compounds present in foods and supplements. The BAC of nettle phenolics was evaluated with an in vitro dynamic digestion of real food matrices: the type of food matrix and chemical characteristic affected the kinetics of release and solubilization, with the highest BAC after duodenal digestion. A study of…
Evaluation of fermentation assisted by Lactobacillus brevis POM, and Lactobacillus plantarum (TR-7, TR-71, TR-14) on antioxidant compounds and organi…
2020
Abstract The impact of fermentation assisted by four different lactic acid bacteria (LAB) on polyphenols, carotenoids, organic acids, and antioxidant capacity of orange-juice milk based beverages was evaluated. Lactobacillus brevis POM, and Lactobacillus plantarum (TR-7, TR-71, TR-14) were used to promote the fermentation of the beverages for 72 h at 37 °C. The bacteria population increased with the elapse of fermentation period, except for beverages inoculated with L. plantarum TR-7. After fermentation period, total polyphenols, total carotenoids and total antioxidant capacity were increased compared to the control ones (non-fermented). Two phenolic acids (DL-3-phenylactic acid and 3–4-dih…
DctA- and Dcu-independent transport of succinate in Escherichia coli : contribution of diffusion and of alternative carriers
2001
Quintuple mutants of Escherichia coli deficient in the C4-dicarboxylate carriers of aerobic and anaerobic metabolism (DctA, DcuA, DcuB, DcuC, and the DcuC homolog DcuD, or the citrate/succinate antiporter CitT) showed only poor growth on succinate (or other C4-dicarboxylates) under oxic conditions. At acidic pH (pH 6) the mutants regained aerobic growth on succinate, but not on fumarate. Succinate uptake by the mutants could not be saturated at physiological succinate concentrations (≤5 mM), in contrast to the wild-type, which had a K m for succinate of 50 µM and a V max of 35 U/g dry weight at pH 6. At high substrate concentrations, the mutants showed transport activities (32 U/g dry weigh…
Sievietes militārajā dienestā: Dienējošu sieviešu pieredze vīriešu dominējošā vidē
2021
Militārā joma vēsturiski un sociāli tiek definēta kā tradicionāli vīrišķīga – tā ir, iespējams, viena no arhetipiski vīrišķīgākajām sociālajām struktūrām Rietumu sabiedrībā (Segal 1995). Taču militārajā dienestā un karadarbībā tik un tā sastopamas arī sievietes. Šajā bakalaura darbā pētīta 23 sieviešu pieredze, kuras visas dienē vai dienējušas Kanādas Bruņotajos spēkos (KBS) pēdējo četrdesmit gadu laikā. Šo sieviešu pieredze apkopota daļēji strukturētās intervijās, kas veiktas gan klātienē, gan rakstiskā formātā. Izmantojot Pjēra Burdjē teoriju par maskulīno dominanci un Reivinas Konelas koncepciju par maskulīno hegemoniju, darbā esmu pētījusi, kā sievietes pieredz militāro vidi caur dzimtē…
Sāpju un traumu nozīme un pieredze profesionālu dejotāju karjerā
2015
Bakalaura darbs “Sāpju un traumu nozīme un pieredze profesionālu dejotāju karjerā” ir pētījums par profesionālu baletdejotāju skatījumu un attieksmi pret ķermeni sāpju un traumu aspektā, sasaistē ar profesijas ikdienas apstākļiem atrodoties sociālā grupā – baleta trupā. Izmantojot Marsela Mausa teorētisko perspektīvu ķermenis tiek skatīts kā instruments un tā veidošanas tehnikas baletā, kā arī Pjēra Burdjē kultūras kapitāla un habitus ietvaru izmantoju, lai aplūkotu sāpju nozīmi, iemiesošanos, normalizēšanu un pozīciju baletā. Pētījuma mērķis - pētīt un izprast no Latvijas Nacionālās Operas baleta trupas dejotāju skatpunkta, kāda ir sāpju un traumu loma un nozīme karjerā. Pētījuma rezultāti…
Lessons Learned from the German Registry for Acute Aortic Dissection Type A (GERAADA) and Expectations for the Future
2014
The German Registry for Acute Aortic Dissection type A (GERAADA) is a prospective observational clinical multicenter registry that was launched in 2006. With more than 2,500 patients included from over 50 recruiting centers it is—to our knowledge—the most representative register for acute aortic dissection type A (AADA) currently available. We examined mortality and post-operative events as well as the influence of various pre- and intraoperative factors on these endpoints. Among patients registered, 30-day mortality is 15.9 %. 13.4 % of patients experienced postoperatively a new neurological deficit and a total of 10.5 % of patients suffered from permanent neurological impairment 30 days a…
