Reactions of Flavonoids with o‑Quinones Interfere with the Spectrophotometric Assay of Tyrosinase Activity
2016
Flavonoids are important food components with antioxidant properties and many of them have been described as tyrosinase inhibitors. Oxidation of quercetin, kaempferol, morin, catechin, and naringenin by mushroom tyrosinase and their influence on the oxidation of l-dopa and l-tyrosine was studied. Reaction rates measured spectrophotometrically and by oxygen consumption differed substantially. All tested flavonoids reacted with 4-tert-butyl-o-benzoquinone and/or 4-methyl-o-benzoquinone, although at different rates. These reactions generated products whose UV-vis spectra either overlapped or did not overlap with the spectrum of dopachrome. They therefore strongly influence the kinetic analysis…
Evaluation of Alternaria mycotoxins in strawberries: quantification and storage condition
2016
Alternariol (AOH), alternariol methyl ether (AME) and tentoxin (TEN) are Alternaria mycotoxins produced by the most common post-harvest pathogens of fruits. The production of these metabolites depends on several environmental factors, mainly temperature, water activity, pH and the technological treatments that have been applied to the product. In this study, the occurrence of AOH, AME and TEN was evaluated in strawberries samples stored at different temperatures ranges (at 22 ± 2 or 6 ± 2°C) and different periods (up to 1 month) simulating the current practice of consumer's storage conditions. Sample extraction was performed using a liquid-liquid extraction method prior to LC-MS/MS analysis…
Monitoring of ticks and tick-borne pathogens through a nationwide research station network in Finland.
2020
In 2015 a long-term, nationwide tick and tick-borne pathogen (TBP) monitoring project was started by the Finnish Tick Project and the Finnish Research Station network (RESTAT), with the goal of producing temporally and geographically extensive data regarding exophilic ticks in Finland. In the current study, we present results from the first four years of this collaboration. Ticks were collected by cloth dragging from 11 research stations across Finland in May September 2015-2018 (2012-2018 in Seili). Collected ticks were screened for twelve different pathogens by qPCR: Borrelia afzelii, Borrelia garinii, Borrelia valaisiana, Borrelia burgdorferi sensu stricto, Borrelia miyamotoi, Babesia sp…
Comparison of growth, acidification and productivity of pure and mixed cultures of Streptococcus salivarius subsp. thermophilus 404 and Lactobacillus…
1994
International audience; Pure and mixed controlled-pH batch cultures of Streptococcus salivarius subsp. thermophilus 404 and Lactobacillus delbrueckii subsp. bulgaricus 398 have been conducted. The characteristics of growth and acidification and the productivity of the cultures were compared. During the mixed cultures, the growth characteristics revealed a pronounced stimulation of S. thermophilus whereas L. bulgaricus metabolism was not significantly improved. The final total population was 1.4 to 4.9 higher than in pure cultures. The acidification characteristics were not enhanced by the mixed culture conditions. The productivity of mixed cultures was 1.7 to 2.4 times higher as compared to…
Beware of the dog! Private linguistic landscapes in two ‘Hungarian’ villages in South-West Slovakia
2015
This study demonstrates how a single type of sign can be connected to language policy on a larger scale. Focusing on the relationship between language policy and language ideologies, I investigate the private Linguistic Landscape (LL) of Hungarians living in two villages in Slovakia. Through an examination of ‘beware of the dog’ signs, it is shown how such signs can be indicative of different language policies. In Slovakia, the Hungarian public LL is often referred to as a threat to the state language and public order. This ideology is reflected on the LL so that there are mostly Slovak-only public signs in bilingual and Hungarian dominant villages. The private realm is the only significant…
Soil feedback does not explain mowing effects on vegetation structure in a semi-natural grassland
2009
Due to its ability to create aboveground conditions that favour plant diversity, mowing is often used to preserve the high conservation value of semi-natural species-rich grasslands. However, mowing can also affect belowground conditions. By decreasing plant carbon supply to soil, mowing can suppress the activity of soil decomposers, diminish plant nutrient availability and thus create a feedback on plant growth. In this study, we first documented the effects of three-year mowing on plant community structure in a species-rich grassland. We found that mowing decreased the total areal cover of woody plants and increased the total cover of leguminous forbs. At the species level, mowing further…
Sinhogarismo de larga duración: Trayectorias vitales e intervención institucional. Investigación aplicada en la ciudad de Valencia
2019
Abordar la cuestión del sinhogarismo desde puntos de vista teóricos que lo sitúan en la casuística individual y definen a la población que sufre sus consecuencias como indigentes, mendigos, vagabundos, etcétera, poniendo en segundo plano el papel de la vivienda e ignorando la necesidad de políticas socio-residenciales sólidas, nos ha llevado a desenfocar este fenómeno y a no identificar, ni reconocer, la vasta heterogenia que caracteriza la composición sociológica de las personas afectadas por la pérdida de este derecho inalienable. Siendo conscientes de las diversas situaciones que engloba la exclusión residencial, pero en un intento por limitar el objeto de la investigación para que resul…
Mujer y representación política institucional en la Comunidad Valenciana. 1977-1995. Diputadas, ministras y cargos institucionales
2014
“Mujer y representación política institucional en la Comunidad Valenciana. 1977-1995. Diputadas, ministras y cargos institucionales” es la primera parte de un trabajo de documentación para un capítulo de “La democracia en la Comunidad Valenciana. Partidos, elites políticas, elecciones y programas políticos”. “Mujer, poder político y democracia paritaria”. Se recoge el papel de la mujer en la vida política de la Comunidad Valenciana en la democracia actual, desde 1977. Es documentación sin elaborar, pero que aporta datos de la presencia de la mujer en las instituciones, partidos y sindicatos. Cuando este completa será una parte de la investigación referida, y de la que ya hay dos publicacion…
Bezvarīgo vara: Masariks, Patočka, Havels
2018
"Bezvarīgo vara” (Moc bezmocných) ir atsauce uz Vāclava Havela eseju ar tādu pašu nosaukumu, kas kļuva par kolektīvās monogrāfijas vadmotīvu un konceptuālo kodolu. Grāmatā ir apkopoti mūsdienu Čehijas un Latvijas zinātnieku – vēsturnieku, filosofu, sociologu, antropologu, lingvistu – aktuālie pētījumi, kā arī pirmo reizi latviešu valodā ir pārtulkoti triju ievērojamo čehu domātāju – Tomāša Garika Masarika, Jana Patočkas un Vāclava Havela teksti. Grāmatā “Bezvarīgo vara: Masariks, Patočka, Havels” iekļauta daļa no pētījumiem, kas tika prezentēti konferencē ar tādu pašu nosaukumu. Tā norisinājās Rīgā, 2017. gada 24. un 25. oktobrī un tās patronese bija prof. Dr. Vaira Vīķe-Freiberga, Latvijas…
