Aproximación neurolingüística al estudio del bilingüismo
2011
El presente trabajo constituye un estado del arte sobre los estudios realizados en el ámbito neurolingüístico y psicolingüístico sobre el cerebro de las personas bilingües. This master's degree dissertation is about the most important debates on the bilingual brain, from a neurolinguistic and psycholinguistic perspective.
Activation of NF-kappaB and IL-8 by yersinia enterocolitica invasin protein is conferred by engagement of rac1 and MAP kinase cascades.
2003
International audience; Yersinia enterocolitica triggers activation of the nuclear factor (NF)-kappaB and production of the proinflammatory chemokine interleukin (IL)-8 in intestinal epithelial cells. This activation is due to adhesion of the bacteria via their outer membrane protein invasin to the host cells. Using Clostridium difficile toxins that specifically inactivate small GTPases, and transfection of inhibitory proteins of the Rho-GTPases, we demonstrate that Rac1, but not Cdc42 or Rho, is required for activation of NF-kappaB by invasin. Invasin activated the mitogen activated protein kinases (MAPK) p38 and c-Jun N-terminal protein kinase (JNK) but not extracellular signal regulated …
The genome sequence of Blochmannia floridanus: Comparative analysis of reduced genomes
2003
Bacterial symbioses are widespread among insects, probably being one of the key factors of their evolutionary success. We present the complete genome sequence of Blochmannia floridanus , the primary endosymbiont of carpenter ants. Although these ants feed on a complex diet, this symbiosis very likely has a nutritional basis: Blochmannia is able to supply nitrogen and sulfur compounds to the host while it takes advantage of the host metabolic machinery. Remarkably, these bacteria lack all known genes involved in replication initiation ( dna A, pri A, and rec A). The phylogenetic analysis of a set of conserved protein-coding genes shows that Bl. floridanus is phylogenetically related to Buch…

Cytotoxic necrotizing factor type 2 produced by virulent Escherichia coli modifies the small GTP-binding proteins Rho involved in assembly of actin s…
1994
Cytotoxic necrotizing factor type 2 (CNF2) produced by Escherichia coli strains isolated from intestinal and extraintestinal infections is a dermonecrotic toxin of 110 kDa. We cloned the CNF2 gene from a large plasmid carried by an Escherichia coli strain isolated from a lamb with septicemia. Hydropathy analysis of the deduced amino acid sequence revealed a largely hydrophilic protein with two potential hydrophobic transmembrane domains. The N-terminal half of CNF2 showed striking homology (27% identity and 80% conserved residues) to the N-terminal portion of Pasteurella multocida toxin. Methylamine protection experiments and immunofluorescence studies suggested that CNF2 enters the cytosol…
E. coli mikrobioloģiskais piesārņojums un riska novērtēšana maltā liellopu gaļā
2016
Escherichia coli ir zarnu traktā sastopama baktērija, kas ārpus tā var pieķerties virsmām, veidojot biofilmu, tādēļ jebkurā kaušanas – pārstrādes etapā var notikt gaļas kontaminācija. EK regula Nr. 2073/2005 norāda, ka E. coli izmanto kā fekālā piesārņojuma indikatoru, pielietojot analītisko metodi ISO 16649-2 β-glikuronidāzes pozitīvo E. coli skaita noteikšanai. Šajā darbā ir novērtēts E. coli piesārņojuma līmenis maltas liellopu gaļas produktos, novērtēta un salīdzināta skaita izmaiņa dabiskā un mākslīgā piesārņojumā, izmantojot izaicinājuma testu. Iegūtie rezultāti ir apmierinoši, jo E. coli skaits produktos, pēc EK regulas Nr. 2073/2005, nepārsniedz minimālo vērtību – 50 KVV/g. Izaicinā…
Safety and potential interaction of immunosuppressive drugs for the treatment of inflammatory bowel disease in elderly patients
2021
Inflammatory bowel diseases, including Crohn's disease and ulcerative colitis, are chronic diseases associated with increased morbidity and reduced quality of life. Age may represent a risk factor for adverse events, due to the multimorbidity and polypharmacy, common in elderly patients. Elderly are often not included in clinical trials evaluating efficacy and safety of study drugs for the treatment of inflammatory bowel diseases. Several drugs, such as aminosalicylates, systemic corticosteroids, immunosuppressant drugs, biological drugs and Janus Kinase inhibitors, are available for the management of inflammatory bowel diseases. With the increasing spectrum of therapeutic options, it is th…
