Metabolic associated fatty liver disease(MAFLD),formerly named“nonalcoholic fatty liver disease”occurs in about one-third of the general population of developed countries worldwide and behaves as a major morbidity and mortality risk factor for major causes of death,such as cardio-vascular,digestive,metabolic,neoplastic and neuro-degenerative ***,progression of MAFLD and its associated systemic complications occur almost invariably in patients who experience the additional burden of intrahepatic and/or systemic inflammation,which acts as disease *** review is focused on the new knowledge about the brain-gut-liver axis in the context of metabolic dysregulations associated with fatty liver,where insulin resistance has been assumed to play an important *** emphasis has been given to digital imaging studies and in particular to positron emission tomography,as it represents a unique opportunity for the noninvasive in vivo study of tissue *** exhaustive revision of targeted animal models is also provided in order to clarify what the available preclinical evidence suggests for the causal interactions between fatty liver,dysregulated endogenous glucose production and insulin resistance.

AIM： To evaluate the possible differences in morphology and immunohistochemical expression of CD3, transforming growth factor 131（TGF-131）, Smad7, α-smooth muscle actin （α-Sma）, and collagen types Ⅰ-Ⅶ of small and large intestine in Smad3 null and wild-type mice. METHODS： Ten null and ten wild-type adult mice were sacrificed at 4 mo of age and the organs （esophagus, small and large bowel, ureters） were collected for histology（hematoxylin and eosin, Masson thrichrome, silver staining）, morphometry and immunohistochemistry analysis. TGF-β1 levels of intestinal tissue homogenates were assessed by ELISA. RESULTS： No macroscopic intestinal lesions were detected both in null and wild-type mice. Histological and morphometric evaluation revealed a significant reduction in muscle layer thickness of small and large intestine in null mice as compared to wild-type mice. Immunohistochemistry evaluation showed a significant increase of CD3＋T cell, TGF-β1 and Smad7 staining in the small and large intestine mucosa of Smad3 null mice as compared to wild-type mice. α-Sma and collagen Ⅰ-Ⅶ staining of small and large intestine did not differ between the two groups of mice. TGF-β1 levels of colonic tissue homogenates were significantly higher in null mice than in wildtype mice. In preliminary experiments a significant reduction of TNBS-induced intestinal fibrosis was observed in null mice as compared to wild-type mice.

Impact of chronic exposure to bevacizumab on EpCAM-based detection of circulating tumor cells

引用

Chinese Journal of Cancer Research 2015年第5期27卷 491-496页

作者： Chiara Nicolazzo Isabella Massimi Lavinia V.Lotti Simone Vespa Cristina Raimondi Fabio maria Pulcinelli angela Gradilone Paola Gazzaniga Dipartimento di Medicina Molecolare Sapienza Università di Roma Dipartimento di Medicina Sperimentale Sapienza Università di Roma

Background： Circulating tumor cells （CTCs） are often undetected through the immunomagnetic epithelial cell adhesion molecule （EpCAM）-based CellSearch~ System in breast and colorectal cancer （CRC） patients treated with bevacizumab （BEV）, where low CTC numbers have been reported even in patients with evidence of progression of disease. To date, the reasons for this discrepancy have not been clarified. This study was carried out to investigate the molecular and phenotypic changes in CRC cells after chronic exposure to BEV in vitro. Methods： The human CRC cell line WiDr was exposed to a clinically relevant dose of BEV for 3 months in vitro. The expression of epithelial and mesenchymal markers and EpCAM isoforms was determined by western blotting and immunofluorescence. To evaluate the impact of EpCAM variant isoforms expression on CTC enumeration by CellSearch, untreated and treated colon cancer cells were spiked into 7.5 mL of blood from a healthy donor and enumerated by CellSearch. Results： Chronic exposure of CRC cell line to BEV induced decreased expression of EpCAM 40 kDa isoform and increased expression EpCAM 42 kDa isoform, together with a decreased expression of cytokeratins （CK）, while no evidence of epithelial to mesenchymal transition （EMT） in treated cells was observed. The recovery rate of cells through CellSearch was gradually reduced in course of treatment with BEV, being 84% , 70% and 40% at l, 2 and 3 months, respectively. Conclusions： We hypothesize that BEV may prevent CellSearch from capturing CTCs through altering EpCAM isoforms.

Informal Settlements： A Shape Grammar Approach

引用

Journal of Civil Engineering and Architecture 2014年第11期8卷 1389-1395页

作者： maria angela Dias School of Architecture and Urbanism Federal University of Rio de Janeiro Rio de Janeiro 22 291-090 Brazil

Informal urban development is seldomly covered in academic studies or professional architectural training. This article sets forth the first stage of a novel study that observes the informal city using the methodology of analysis of architecture called shape grammars. The idea is to recognize peculiarities in the occupation of the land and the volumetric features of the buildings. Rocinha favela, in Rio de Janeiro, Brazil, is taken as a case study with the primary aim of extrapolating a set of rules for its morphological features so that these rules can be used to generate new shapes, whilst bearing in mind the issues of adaptation and transformation which are so characteristic of informal settlements. There is some expectation that this study may help improve the housing and public space in the favela and enable new housing programs to observe the way the buildings and different architectural elements combined, forming a new channel of interchange with the spatial organization of the favela.
