JEJUNAL VILLUS ABSORPTION AND PARACELLULAR TIGHT JUNCTION PERMEABILITY ARE MAJOR ROUTES FOR EARLY INTESTINAL UPTAKE OF FOOD-GRADE TIO2 PARTICLES: AN IN VIVO AND EX VIVO STUDY IN MICE

Jejunal villus absorption and paracellular tight junction permeability are major routes for early intestinal uptake of food-grade TiO2 particles: an in vivo and ex vivo study in mice

Abstract Background Food-grade TiO2 (E171 in the EU) is widely used as a coloring agent in foodstuffs, including sweets.Chronic dietary exposure raises concerns for human health due to proinflammatory properties and the ability to induce and promote preneoplastic lesions in the rodent gut.Characterization of intestinal TiO2 uptake is essential for

Familia y modelos de reproducción social de la nobleza española en los siglos XV-XIX: el surgimiento del individualismo

This work attempts to approach the changes in the models of social reproduction Flea of the noble family from the 15th to the 19th century in Spain, as well as the emergence of individualism.In this way, starting with a family analysis of two complete noble lineages, the de la Cueva and Fernández de Córdoba, which cover 54 houses or genealogical

Microspore culture reveals high fitness of B. napus-like gametes in an interspecific hybrid between Brassica napus and B. oleracea.

The strategies of crossing B.napus with parental species play important role in broadening and improving the genetic basis of B.napus by the introgression of genetic resources from parental species.With these strategies, it is easy to select new types of B.napus, but difficult to select new types of B.rapa or B.oleracea by self-pollination.This cha

Pan-cancer single cell and spatial transcriptomics analysis deciphers the molecular landscapes of senescence related cancer-associated fibroblasts and reveals its predictive value in neuroblastoma via integrated multi-omics analysis and machine learning

IntroductionCancer-associated fibroblasts (CAFs) are a diverse group of cells that significantly contribute to reshaping the tumor microenvironment (TME), and no research has systematically explored the molecular landscapes of senescence related CAFs (senes CAF) in NB.MethodsWe utilized pan-cancer single cell and spatial transcriptomics analysis to
