Tracking mite trophic interactions by multiplex PCR
2020
Background A thorough knowledge of trophic webs in agroecosystems is essential to achieve successful biological pest control. Phytoseiid mites are the most efficient natural enemies of tetranychid mites, which include several important pests worldwide. Nevertheless, phytoseiids may feed on other food sources including other microarthropods, plants and even other phytoseiids (intraguild predation), which can interfere with biological control services. Molecular gut content analysis is a valuable tool for characterizing trophic interactions, mainly when working on microarthropods such as mites. We have designed new primers for Phytoseiidae, Tetranychidae and Thysanoptera identification and th…
Identification of mycorrhiza-regulated genes with arbuscule development-related expression profile
2004
Suppressive subtractive hybridisation was applied to the analysis of late stage arbuscular mycorrhizal development in pea. 96 cDNA clones were amplified and 81, which carried fragments more than 200 nt in size, were sequence analysed. Among 67 unique fragments, 10 showed no homology and 10 were similar to sequences with unknown function. RNA accumulation of the corresponding 67 genes was analysed by hybridisation of macro-arrays. The cDNAs used as probes were derived from roots of wild type and late mutant pea genotypes, inoculated or not with the AM fungus Glomus mosseae. After calibration, a more than 2.5-fold mycorrhiza-induced RNA accumulation was detected in two independent experiments…

Extracellular vesicle DNA from human melanoma tissues contains cancer-specific mutations
2022
Liquid biopsies are promising tools for early diagnosis and residual disease monitoring in patients with cancer, and circulating tumor DNA isolated from plasma has been extensively studied as it has been shown to contain tumor-specific mutations. Extracellular vesicles (EVs) present in tumor tissues carry tumor-derived molecules such as proteins and nucleic acids, and thus EVs can potentially represent a source of cancer-specific DNA. Here we identified the presence of tumor-specific DNA mutations in EVs isolated from six human melanoma metastatic tissues and compared the results with tumor tissue DNA and plasma DNA. Tumor tissue EVs were isolated using enzymatic treatment followed by ultra…
Elementos ideológicos en las unidades fraseológicas con la palabra mujer en el Diccionario académico en los siglos XVIII y XIX
2017
This paper explores ideological elements regarding gender in phraseological units with the word mujer(‘woman’) in the different editions of the dictionarypublished by Real Academia Española during the 18th and the 19th centuries. First, the ideological content in the phraseological units themselves is analyzed. Second, phenomena related to subjectivity in the definitions are analyzed: this evidences subjectivity not only in the different phraseological units presented in the dictionary, but also in the discourse of the academics. In order to approach the first issue, a typology of the different phraseological units according to their syntactic-semantic properties is provided: this categoriz…
Real-world experience with obeticholic acid in patients with primary biliary cholangitis
2021
Background & aims Obeticholic acid (OCA) is the second-line treatment approved for patients with primary biliary cholangitis (PBC) and an inadequate response or intolerance to ursodeoxycholic acid. We aimed to evaluate the effectiveness and safety of OCA under real-world conditions. Methods Patients were recruited into the Italian PBC Registry, a multicentre, observational cohort study that monitors patients with PBC at national level. The primary endpoint was the biochemical response according to Poise criteria; the secondary endpoint was the biochemical response according to normal range criteria, defined as normal levels of bilirubin, alkaline phosphatase (ALP), and alanine aminotransfer…
Heterozygote advantage and pleiotropy contribute to intraspecific color trait variability
2022
The persistence of intrapopulation phenotypic variation typically requires some form of balancing selection because drift and directional selection eventually erode genetic variation. Heterozygote advantage remains a classic explanation for the maintenance of genetic variation in the face of selection. However, examples of heterozygote advantage, other than those associated with disease resistance, are rather uncommon. Across most of its distribution, males of the aposematic moth Arctia plantaginis have two hindwing phenotypes determined by a heritable one locus-two allele polymorphism (genotypes: WW/Wy = white morph, yy = yellow morph). Using genotyped moths, we show that the presence of o…
Vaļņu trases iekļaušana skolu infrastruktūrā, to pieejamība un ietekme uz sporta stundām
2022
Darba autors diplomdarba tēmu balsta uz problēmas būtību, kas sevī ietver skolas infrastruktūras neizmantošanu vai tās neesamību, tādā veidā radot priekšstatu par ekstrēmā sporta pieejamību un ietekmi uz sporta stundām. Diplomdarba mērķis ir, pēc Skola 2030 vadlīnijām attiecībā uz sporta stundu norisi, balstoties uz teorijas materiālu, kā arī veiktās aptaujas datu analīzi, definēt sekmīgu ekstrēmā sporta integrācijas modeļa izveidi skolas sporta stundām. Diplomdarba teorētiskajā daļā tiek hronoloģiski analizēta ekstrēmā sporta teorija. Tiek uzskaitīti sasniegumi Latvijas un pasaules mērogā, kā arī atspoguļota laika gaitā esošā skolas vecuma bērnu interese par ekstrēmo sportu. Tiek aprakstīt…
Diskriminācija darba tirgū
2022
Bakalaura darba tēma ir “Diskriminācija darba tirgū”. Neskatoties uz sabiedrības cīņu ar diskrimināciju, šo parādību var satikt arī attīstītajās valstīs. Jebkura veida diskriminācija negatīvi ietekmē darba tirgus un uz ekonomiku kopumā, kā arī diskriminācija atstāj lielas sociālajās sekās. Šajā bakalaurā darbā autors apskata diskriminācijas cēloņus un veidus darba tirgū, kā arī diskriminācijas sekas. Bakalaurā darbā padziļināti tiek apskatīti dzimumu, rasu, vecumu, reliģijas un veselības stāvokļa diskriminācijas. Veikta analīze par katru no šiem faktoriem Latvijā un Eiropā kopumā. Kā arī izveidots empīriskais pētījums par vienu no diskriminācijas veidiem. Empīriskajā pētījumā dzimuma diskri…
