Transcriptional study of photoperiodic response in aphids and characterization of candidate photoperiodic photoreceptors
2020
Acyrthosiphon pisum es una especie de pulgón altamente estacional. Durante la estación favorable, únicamente se producen hembras partenogenéticas vivíparas (virginóparas). En otoño, cuando hay menos luz (el fotoperiodo es más corto), A. pisum percibe la diferencia y las virginóparas paren machos y luego hembras sexuadas (ovíparas). Tras aparearse, las ovíparas ponen huevos que resisten el invierno y eclosionan en primavera, reiniciando el ciclo. Algunos mutantes que ocurren de forma natural no responden al fotoperiodo y se reproducen asexualmente durante todo el año. Se denominan anholocíclicos en contraposición a los holocíclicos, que tienen fase sexual. Se desconocen los mecanismos molecu…
Early evolutionary colocalization of the nuclear ribosomal 5S and 45S gene families in seed plants: evidence from the living fossil gymnosperm Ginkgo…
2012
In seed plants, the colocalization of the 5S loci within the intergenic spacer (IGS) of the nuclear 45S tandem units is restricted to the phylogenetically derived Asteraceae family. However, fluorescent in situ hybridization (FISH) colocalization of both multigene families has also been observed in other unrelated seed plant lineages. Previous work has identified colocalization of 45S and 5S loci in Ginkgo biloba using FISH, but these observations have not been confirmed recently by sequencing a 1.8 kb IGS. In this work, we report the presence of the 45S–5S linkage in G. biloba, suggesting that in seed plants the molecular events leading to the restructuring of the ribosomal loci are much o…
Liikunnanopettajaksi vuosina 1984 - 2004 valmistuneiden työtyytyväisyys
2012
Tutkimuksen tarkoituksena oli selvittää liikunnanopettajiksi vuosina 1984–2004 valmistuneiden työtyytyväisyyttä ja siihen vaikuttavia tekijöitä. Tutkimukseen osallistui yhteensä 621 liikunnanopettajan ammatissa toimivaa henkilöä (naisia 326, miehiä 295). Tutkimus suoritettiin strukturoiduilla kyselylomakkeilla vastavalmistuneille liikunnanopettajille vuonna 2008 sekä kokeneemmille liikunnanopettajille vuonna 2009. Tutkimusaineiston analysointiin käytettiin t-testiä sekä yksi- ja kaksisuuntaista varianssianalyysia. Pääkomponenttianalyysinn avulla työtyytyväisyyttä muodostavat tekijät luokiteltiin kuuteen eri komponenttiin. Tutkimuksen tulokset osoittivat, että 80 prosenttia liikunnanopettaji…
Characterization and transcription studies of a phytochelatin synthase gene from the solitary tunicate Ciona intestinalis exposed to cadmium.
2014
The major thiol-containing molecules involved in controlling the level of intracellular ROS in eukaryotes, acting as a nonenzymatic detoxification system, are metallothioneins (MTs), glutathione (GSH) and phytochelatins (PCs). Both MTs and GSH are well-known in the animal kingdom. PC was considered a prerogative of the plant kingdom but, in 2001, a phytochelatin synthase (PCS) gene was described in the nematode Caenorhabditis elegans; additional genes encoding this enzyme were later described in the earthworm Eisenia fetida and in the parasitic nematode Schistosoma mansoni but scanty data are available, up to now, for Deuterostomes. Here, we describe the molecular characteristics and transc…
Cold Exposure Affects Lipid Metabolism, Fatty Acids Composition and Transcription in Pig Skeletal Muscle
2021
Cold exposure promotes glucose oxidation and modulates the lipid metabolism in adipose tissue, but it is still not fully clear whether cold exposure could affect meat quality and fatty acid metabolism in skeletal muscle of pig in vivo. Here, we kept finishing pigs under cold or room temperature overnight and determined the effects of cold exposure on meat quality, fatty acids composition and transcriptional changes in skeletal muscle of pigs. We found that cold exposure significantly reduced the meat colour24 h and pH24 h, without affecting carcass characteristics and other meat quality traits. Considerable changes were found in the proportions of individual fatty acids and the total conten…
Angular specifiska TypeScript pirmkoda ģenerēšana ar Roslyn .NET kompilatora platformu
2017
Modernos tīmekļa risinājumos datu modelis tiek dublēts starp servera un klienta lietotnēm. Šo informāciju vajag uzturēt atbilstošu abos galos - mainoties datu modelim, izmaiņas vajag atspoguļot gan servera, gan klienta pusē (kas atbilst dažādām izpildes vidēm un dažādām programmēšanas valodām). Lai izvairītos no manuālās izmaiņu sinhronizācijas, darbā tiek aplūkota pirmkoda ģenerēšanas pieeja, kas ļauj šo procesu automatizēt. Darbā identificēti dublētie informācijas vienumi tieši ASP.NET (servera pusē) un Angular (klienta pusē) tīmekļa risinājumos, izpētīti esošie problēmas risinājumi, kas veic pirmkoda ģenerēšanu, kā arī izpētītas .NET pirmkoda analīzes un TypeScript pirmkoda ģenerēšanas i…
«Cual doctora en cielo graduada...». The feminine poetry for literary contests in honor of the beatification and canonization of Teresa of Ávila (Val…
2015
L’objectiu d’aquest estudi és examinar les composicions poètiques aportades per dones als tres certàmens celebrats a València i Barcelona, amb motiu de la beatificació (1614) i posterior canonització (1622) de Teresa de Jesús; dos moments clau per a la consolidació de la fama de la carmelitana avilesa que van possibilitar l’exhibició pública i impressió de poesia femenina. Analitzem també la participació femenina catalana al certamen celebrat a Saragossa el 1614 per la beatificació. L’estudi està enfocat des d’una perspectiva femenina, a través de la revisió de dihuit poesies amb signatura de dones que ens han transmès les extenses relacions impreses. Al llarg del comentari dels poemes, ana…
Effects of Polyacrylic Acid Pre-Treatment on Bonded-Dentine Interfaces Created with a Modern Bioactive Resin-Modified Glass Ionomer Cement and Subjec…
2018
Objectives: Resin-modified glass ionomer cements (RMGIC) are considered excellent restorative materials with unique therapeutic and anti-cariogenic activity. However, concerns exist regarding the use of polyacrylic acid as a dentine conditioner as it may influence the bonding performance of RMGIC. The aim of this study was to evaluate the effect of different protocols for cycling mechanical stress on the bond durability and interfacial ultramorphology of a modern RMGIC applied to dentine pre-treated with/without polyacrylic acid conditioner (PAA). Methods: The RMGIC was applied onto human dentine specimens prepared with silicon-carbide (SiC) abrasive paper with or without the use of a PAA c…
Pro-Degradant Activity of Naturally Occurring Compounds on Polyethylene in Accelerate Weathering Conditions
2019
In this work, naturally occurring compounds, such as Vitamin E (VE) and Ferulic Acid (FA), at high concentrations, have been considered as pro-degradant agents for Low Density Polyethylene (PE). However, all obtained results using the naturally occurring molecules as pro-oxidant agents for PE have been compared with the results achieved using a classical pro-oxidant agent, such as calcium stearate (Ca stearate) and with neat PE. The preliminary characterization, through rheological, mechanical and thermal analysis, of the PE-based systems highlights that the used naturally occurring molecules are able to exert a slight plasticizing action on PE and subsequently the PE rigidity and crystalli…
Regulatory networks underlying mycorrhizal development delineated by genome-wide expression profiling and functional analysis of the transcription fa…
2017
Background: Ectomycorrhizal (ECM) fungi develop a mutualistic symbiotic interaction with the roots of their host plants. During this process, they undergo a series of developmental transitions from the running hyphae in the rhizosphere to the coenocytic hyphae forming finger-like structures within the root apoplastic space. These transitions, which involve profound, symbiosis-associated metabolic changes, also entail a substantial transcriptome reprogramming with coordinated waves of differentially expressed genes. To date, little is known about the key transcriptional regulators driving these changes, and the aim of the present study was to delineate and functionally characterize the trans…
