Sng1 associates with Nce102 to regulate the yeast Pkh–Ypk signalling module in response to sphingolipid status
2016
International audience; All cells are delimited by biological membranes, which are consequently a primary target of stress-induced damage. Cold alters membrane functionality by decreasing lipid fluidity and the activity of membrane proteins. In Saccharomyces cerevisiae, evidence links sphingolipid homeostasis and membrane phospholipid asymmetry to the activity of the Ypk1/2 proteins, the yeast orthologous of the mammalian SGK1-3 kinases. Their regulation is mediated by different protein kinases, including the PDK1 orthologous Pkh1/2p, and requires the function of protein effectors, among them Nce102p, a component of the sphingolipid sensor machinery. Nevertheless, the mechanisms and the act…
Combination of Freezing, Low Sodium Brine and Cold Smoking on the Quality and Shelf-Life of Sea Bass (Dicentrarchus labrax L.) Fillets as a Strategy …
2021
Aquaculture is playing a leading role in both meeting the growing demand for seafood and increasing the sustainability of the fish production sector. Thus, innovative technologies that improve its sustainability, competitiveness, and safety are necessary for growth in the sector. This study aimed to develop cold smoked sea bass fillets from aquaculture. The aptitude of frozen and fresh fillets for cold smoking was investigated by processing both fresh and thawed fillets kept previously at &minus
QT interval heterogeneities induced through local epicardial warming/cooling. An experimental study
2014
[EN] ntroduction and objectives Abnormal QT interval durations and dispersions have been associated with increased risk of ventricular arrhythmias. The present study examines the possible arrhythmogenic effect of inducing QT interval variations through local epicardial cooling and warming. Methods In 10 isolated rabbit hearts, the temperatures of epicardial regions of the left ventricle were modified in a stepwise manner (from 22 °C to 42 °C) with simultaneous electrogram recording in these regions and in others of the same ventricle. QT and activation-recovery intervals were determined during sinus rhythm, whereas conduction velocity and ventricular arrhythmia induction were determined dur…
Modified climate with long term memory in tree ring proxies
2015
ABSTRACT : A contribution to the PAGES Asia2k Working Group. ABSTRACT: Long term memory (LTM) scaling behavior in worldwide tree ring proxies and subsequent climate reconstructions is analyzed for and compared with the memory structure inherent to instrumental temperature and precipitation data. Detrended fluctuation analysis is employed to detect LTM and its scaling exponent a is used to evaluate LTM. The results show that temperature and precipitation reconstructions based on ring width measurements (mean \alpha =0.8) contain more memory than records based on maximum latewood density (mean \alpha =0.7). Both exceed the memory inherent to regional instrumental data (\alpha =0.6 for tempera…
Production of neutron-rich isotopes in fission of uranium induced by neutrons of 20 MeV average energy
2000
In the context of a parameter study conducted by several laboratories for future European radioactive beam facilities based on fast-neutron induced fission, in particular for the SPIRAL-II project at GANIL, we have measured the yields of neutron-rich isotopes in the mass range of 88 to 144. These nuclei were obtained as fission products of natural uranium bombarded by neutrons of 20 MeV average energy emitted by a thick carbon target irradiated by 50 MeV deuterons. Yields have been measured using on-line mass separation with the ion-guide method. Compared with proton-induced fission at 25 MeV the magnitude of cross-sections, except for the symmetric region, is similar. Z-distributions of is…

Data from the study: Strong temporal dynamics of ecosystem services through succession
2021
We used a nation-wide forest dataset from the Swedish National Forest Inventory (NFI) and the Survey of Forest Soils and Vegetation, covering an area of 400,000 km2 of production forests. The inventory uses a regular sampling grid with a randomly selected starting point covering the whole country, with each tract being surveyed once every 5 years. The tracts, which are rectangular in shape and are of different dimensions in different parts of the country, consists of 8 (in the north) to 4 (in the south) circular sample plots. The circular plots have different radii (5-20 meters) to ensure that the variables recorded characterize the ongoing forest dynamics and management. We used only plots…
BiZact tonsilektomijas un konvencionālās tonsilektomijas metožu salīdzinājums
2022
Paskaidrojošā informācija: Tonsilektomija ir viena no visbiežāk veiktajām ķirurģiskajām operācijām cilvēces vēsturē. Tonsilektomija tehnoloģijas un procedūras gadu gaitā ir attīstījušās, lai uzlabotu pacientu aprūpi saistībā ar intraoperācijas un pēcoperācijas riskiem. Mērķis: Šī pētījuma mērķis ir salīdzināt BiZact tonsilektomijas metodi ar tradicionālo «aukstās pieejas» tērauda tonsilektomijas metodi attiecībā uz ķirurģiskajiem rezultātiem. Nolūks: Klasiskā «aukstās pieejas» tērauda tonsilektomijas metode ir viena no visbiežāk izmantotajām metodēm, un tā ir balstīta uz tonsilektomijas instrumentiem, jo ar tiem ir viegli strādāt, tiem nav nepieciešama elektrība (un līdz ar to tie ir vienkā…
"Waiting for Godot?" : Lithuania and the European Security Order in the 21-century
2000
Lietuvos užsienio ir saugumo politikos principai, kryptys ir pagrindiniai tikslai liko iš esmės nepakitę nuo pat valstybingumo atkūrimo, tačiau politinių sprendimų priėmimo kontekstas per tą laiką gerokai pasikeitė ir keičiasi toliau. Vidurio ir Rytų Europoje žlugus komunistiniams režimams, Šaltojo karo tvarka žlugo neįtikėtinai greitai. 2000 m. aiškėja, kad strateginė aplinka ir mūsų saugumo suvokimas taip pat pakito. Nors Vidurio ir Rytų Europos lyderiai nepamiršta sovietinės praeities, pastarieji dešimt metų leidžia tikėtis, kad šioms valstybėms pavyks sėkmingai integruotis į Vakarų Europos struktūras. 1999 m. Kosovo kampanija privertė peržiūrėti tarptautinio saugumo sampratą, Europos Są…
