Also, it was reported that the R. canina fruit, with its high ascorbic acid, phenolics and flavonoids contents, have antioxidant, antimutagenic and anticarcinogenic effects. Antioxidants neutralize free radicals, which cause oxidative damage to lipids, proteins, and nucleic acids and thus protect the organism. Research studies conducted on this topic have shown that natural antioxidants are involved in protection against many diseases: cancer, cardiovascular diseases and osteoporosis. Different processing and storage methods of the fruit could affect the bioactive nutrients while preserving the antioxidant capacity of them is very important. The aim of this study was to evaluate the effect of storage in a dry or frozen state on the antioxidants content of R. canina fruit. The evaluation involved determination of carotenes, ascorbic acid and total polyphenols using spectrophotometrically methods. Analysis performed on the R. canina fruit showed significant changes in the antioxidants content in fresh, dried and frozen fruit during storage.","PeriodicalId":6413,"journal":{"name":"“Agriculture for Life, Life for Agriculture” Conference Proceedings","volume":"53 1","pages":"523 - 528"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84698729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For GC-MS technique, fatty acid methyl esters (FAMEs) identification in the samples was performed by comparison of the retention times (RT) and the mass/charge (m/z) ratio characteristic of each FAME component in the reference standards used (F.A.M.E. Mix C4 - C24 and SRM®2377). FAMEs quantification from food samples was realized by applying correction factors calculated based on reference standards. NMR spectra were recorded on a Bruker Advance 400 MHz spectrometer, operating at 9.4 Tesla corresponding to the resonance frequency of 400.13 MHz for the 1H nucleus. The NMR spectra was recorded directly on the oil without any sample preparation.

Some of them, NPs like Ag, Au and oxides of Al, Ti, Si and Zn have harmful effect on the cells of microorganisms. Iron NPs are expected to be nontoxic, due to using Fe atom in several pathways of cell metabolism and, therefore, low iron toxicity. The use of iron NPs in technologies for remedying polluted environment was caused by their efficiency in reduction reactions, mobility, and high reactivity, due to the high surface area. The present study aims to determine the effect of magnetite (Fe3O4), zero-valent iron Fe(0) NPs, and fluorinated dinitroaniline herbicide trifluralin on growth of mycelial fungi. Fungal strains were isolated from soil long-term polluted with obsolete pesticides, DDT and trifluralin. The inhibition activity of iron NPs and trifluralin was evaluated using express-method. Each fungal strain had an individual reaction to the solutions of iron nanoparticles. At the same time, Fe(0) NPs, as well as magnetite NPs, had a stimulating effect on the formation and maturation of spores of micromycetes. Addition of trifluralin to the culture medium had a growth inhibition effect on micromycetes, but this effect was reduced, when trifluralin was mixed and incubated with iron NPs for 1 hour before.","PeriodicalId":6413,"journal":{"name":"“Agriculture for Life, Life for Agriculture” Conference Proceedings","volume":"2 1","pages":"542 - 547"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73096666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The rearing of marine living resources in controlled environments is one of NIMRD’s constant concerns. Golden gray mullet Liza aurata (Risso, 1810) is spread in the Mediterranean, Black and Caspian Seas, as well as along the Atlantic coast, and culture in extensive and semi-intensive enclosures has been practiced worldwide for centuries, especially in the Far East and the Mediterranean, reaching a global production of 134,329 tons in 2010. The species’ potential for aquaculture is enhanced by its eurihalyne and eurithermal adaptability, allowing it to grow in a variety of ecosystems. The biological material used for the experiment was represented by golden gray mullet fingerlings fished using the beach seine from the Black Sea. They were monitored for health state, growth rythm (mean length and weight determinations), behavior under RAS conditions, survival rate and overall adaptability. The growth of juveniles after 90 days was 89.2% for total length and 246% for mean biomass. Concerning overall adaptability, after approximately one month, the golden gray mullet individuals fully adapted to rearing in the RAS tanks and handling during measurements. Moreover, the food administered (Skretting Classic K) was easily accepted, active feeding behavior being observed even in the presence of NIMRD’s staff. The fish’s health state was good, with no mortalities caused by infections or parasites. The survival rate upon completion of the two monitoring months was 76.66% (23 of the 30 individuals included in the experiment). The preliminary results obtained showed a good adaptability and a normal growth rate, which makes Liza aurata a potential candidate for aquaculture targeting the national and regional market.","PeriodicalId":6413,"journal":{"name":"“Agriculture for Life, Life for Agriculture” Conference Proceedings","volume":"54 3-4","pages":"149 - 154"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72564076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The disease is characterised by calcification of soft tissues including tendons, joint capsules, and ligamentous attachments to bone. A retrospective radiographic study was conducted to investigate the presence and distribution of the DISH in dogs. For this goal were revised medical records from the radiology service of Faculty of Veterinary Medicine Bucharest for dogs that had a radiographic report that described the presence of DISH at spine level. The signalments of all dogs were taken from their medical records. From 531 dogs of 19 breeds, 11 dogs (Cross breed = 3; Rottweiler = 3; Boxer = 2; Golden retriever = 2; German shepherd = 1) were diagnosed with DISH, representing 2.07%. Of these, 5 were females and 6 males, aged between 6 and 15 years (an average of 9.81 years). Following the radiographic evaluation, a total of 74 vertebral segments affected by DISH were identified, and the number of vertebral segments affected per dogs varied between 4 and 10. In all cases, the DISH was accompanied by spondylosis deformans. Although the presence of flowing calcification in the ventral aspects of adjacent vertebral bodies is conclusive for classification as DISH, however it is recommended obtaining supplementation data through modern imaging exams on the vertebral structures.","PeriodicalId":6413,"journal":{"name":"“Agriculture for Life, Life for Agriculture” Conference Proceedings","volume":"73 1","pages":"490 - 494"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80036762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
