Anti-Human CD9 Fab Fragment Antibody Blocks the Extracellular Vesicle-Mediated Increase in Malignancy of Colon Cancer Cells.
2022
Intercellular communication between cancer cells themselves or with healthy cells in the tumor microenvironment and/or pre-metastatic sites plays an important role in cancer progression and metastasis. In addition to ligand–receptor signaling complexes, extracellular vesicles (EVs) are emerging as novel mediators of intercellular communication both in tissue homeostasis and in diseases such as cancer. EV-mediated transfer of molecular activities impacting morphological features and cell motility from highly metastatic SW620 cells to non-metastatic SW480 cells is a good in vitro example to illustrate the increased malignancy of colorectal cancer leading to its transformation and aggressive b…
Cardiovascular Health in Migrants. Current status and issues for prevention. A Collaborative Multidisciplinary Task Force Report
2014
OBJECTIVES: To review information on cardiovascular health and migration, to stress the attention of researchers that much needs to be done in the collection of sound data in Italy and to allow policy makers identifying this issue as an important public health concern. BACKGROUND: In Italy, the rate of immigrants in the total number of residents increased from 2.5% in 1990 to 7.4% in 2010, and currently exceeds 10% in regions such as Lombardia, Emilia Romagna and Toscana. METHODS: A consensus statement was developed by approaching relevant Italian national scientific societies involved in cardiovascular prevention. Task force members were identified by the president and/or the boards of eac…
REAL HUMANS? : Affective imaginaries of the human and its Others in the Swedish TV series Äkta människor
2019
According to the Swedish science fiction TV series Äkta människor (Real Humans, SVT and Matador film 2012-2014), humanoid robots called “hubots” are replacing the human workforce in care work and assembly line industries. Against the backdrop of current debates about immigration and citizenship in the Nordic countries, this article does a close, contextual reading of the series, exploring how the hubots influence work and family life. We are particularly interested in how hubots tie in with the cultural circulation of affect in relation to Otherness and how responses towards the “not-quite” human or dehumanized Other are negotiated in the present-day Nordic cultural imaginaries. What kinds …
Oral health survey of the child population in the Valencia Region of Spain (2004)
2006
Introducción (fundamento y objetivo): La finalidad de establecer una periodicidad sexenal para estudiar la evolución de salud oral infantil unido a importantes cambios demográficos asociados con la inmigración en la Comunidad Valenciana han motivado este trabajo. Material y método: Con una muestra seleccionada al azar de 509 niños de 6 años, 478 de 12 años y 401 de 15-16 años se ha realizado un estudio de corte transversal. Los exploraciones clínicas fueron realizadas por odontólogos calibrados (Kappa > 0.85). Resultados: La prevalencia de caries en dentición temporal a los 6 años es del 32% (Icod=1.08) y en dentición permanente es de 42.5% a los 12 años (ICAOD=1.07) y del 55.9% a los 15-16…
Kvalificētu veselības aprūpes speciālistu migrācija starp Latviju un ārvalstīm: Emigrācijas un reemigrācijas cēloņu analīze
2021
Bakalaura darbs “Kvalificētu veselības aprūpes speciālistu migrācija starp Latviju un ārvalstīm: Emigrācijas un reemigrācijas cēloņu analīze” aplūko migrācijas tendences minētajā cilvēku grupā periodā no 2000. līdz 2020. gadam. Satraukumu izraisošos emigrantu apjomus, kā arī salīdzinoši zemo reemigrantu skaitu ir nepieciešams izlīdzināt, lai migrācijas tendences nosūtītājvalstij nāktu par labu, nevis ietekmētu to negatīvi. Darba mērķis ir noskaidrot un analizēt emigrācijas un reemigrācijas cēloņus veselības aprūpes speciālistu vidū, kuri veido emigrācijas un potenciāli reemigrācijas plūsmu no Latviju uz ārvalstīm un atpakaļ. Autores pētījums noskaidro esošo un topošo veselības aprūpes speci…
The Status of EGFR Modulates the Effect of miRNA-200c on ZEB1 Expression and Cell Migration in Glioblastoma Cells
2020
Migration of glioblastoma cells into surrounding tissue is one of the main features that makes this tumor incurable. We evaluated whole-genome miRNA expression profiling associated with different EGFR amplification patterns in 30 cases of primary glioblastoma. From the 64 miRNAs that showed differential expression between tumors with a high level of EGFR amplification and tumors without EGFR amplification, 40% were related with cell migration, being miR-200c the most differentially expressed between these two groups. We investigated the effect of miR-200c on ZEB1 expression and cell migration in an in vitro transfection model with a miR-200c mimic, a miR-200c inhibitor and siRNA targeting E…
In vivo imaging and quantification of the continuous keratin filament network turnover
2008
Keratin polypeptides are major components of the epithelial cytoskeleton forming a filamentous 3D-network. Like intermediate filament polypeptides of other cell types, keratins make up a stable, but elastic network that is responsible for mechanical stress resilience. At the same time the keratin network is able to change its shape during development, cell division, metastasis and cell migration.
Molecular and isotopic composition of free hydrocarbon gases from Sicily, Italy
2004
[1] Chemical and isotopic data have been used as geochemical tracers for a genetic characterization of hydrocarbon gases from a total of eleven manifestations located in Eastern and Central-Southern Sicily (Italy). The molecular analysis shows that almost all the samples are enriched in methane (up to 93.2% Vol.), with the exception of four gas samples collected around Mt. Etna showing high mantle-derived CO2 content. Methane isotope signatures suggest that these are thermogenic gases or a mixture between thermogenic gases and microbial gases. Although samples from some mud volcanoes in Southern Sicily (Macalube di Aragona) show isotope signatures consistent with a mixing model between ther…
Applications and stereoselective syntheses of P-chirogenic phosphorus compounds.
2016
International audience; Phosphorus compounds bearing chirality on the P-center are usually qualified as P-chirogenic or P-stereogenic. This chemical class concerns natural products, agrochemistry, molecular materials, biology and pharmacy, although it is certainly in coordination chemistry and in asymmetric catalysis using chiral transition metal complexes that P-chirogenic phosphorus compounds are the most used. The chiral phosphine ligands and their uses in asymmetric metal-catalyzed reactions have been widely reviewed in literature. However, an overview covering the applications as well as the stereoselective syntheses of all classes of phosphorus compounds has not yet been provided. Thi…
Data from: Effects of food abundance and early clutch predation on reproductive timing in a high Arctic shorebird exposed to advancements in arthropo…
2017
Climate change may influence the phenology of organisms unequally across trophic levels and thus lead to phenological mismatches between predators and prey. In cases where prey availability peaks before reproducing predators reach maximal prey demand, any negative fitness consequences would selectively favor resynchronization by earlier starts of the reproductive activities of the predators. At a study site in northeast Greenland, over a period of 17 years, the median emergence of the invertebrate prey of Sanderling Calidris alba advanced with 1.27 days per year. Yet, over the same period Sanderling did not advance hatching date. Thus, Sanderlings increasingly hatched after their prey was m…
