Here, we describe the use of monolayers of intestinal epithelial cells derived from intestinal organoids and transcriptomics to investigate the direct effects of dietary protein sources on epithelial function. Mechanically dissociated 3 D organoids of mouse duodenum were used to generate a polarized epithelium containing all cell types found in the tissue of origin. The organoid-derived cell monolayers were exposed to 4%(w/v) of ‘undigested(non-hydrolysed)-soluble' fraction of protein sources used as feed ingredients [soybean meal(SBM) and casein], or alternative protein sources(spray dried plasma protein, and yellow meal worm), or controls for 6 h prior to RNA isolation and transcriptomics. All protein sources altered expression of unique biological processes in the epithelial cells. Exposure of intestinal organoids to SBM downregulated expression of retinol and retinoid metabolic processes as well as cholesterol and lipid biosynthetic pathways, consistent with the reported hypotriglyceridaemic effect of soy protein in vivo. These findings support the use of intestinal organoids as models to evaluate complex interactions between dietary ingredients and the intestinal epithelium and highlights some unique host effects of alternative protein sources in animal feed and potentially human food.

矿物学报 2013年第S1期33卷 107-107页

作者： wells M A Ramanaidou E R CSIRO Earth Science & Resource Engineering Australian Resources Research CentrePO Box 1130Bentley WA 6102Australia

Automated core scanning technologies for mineralogical characterisation of diamond core, drill chips pulps is now an established technique, particularly in the Australian iron ore industry, for mineral analysis in exploration and mining. Application of reflectance spectroscopy over the 400–2500 nm, visible to near-infrared wavelength range, has been used to characterise the iron ore oxide mineralogy of bedded iron deposit (BID) derived iron ores in India (Thangavelu et al., 2011) and Brazil (da Costa et al., 2009), and used to define the ore and gangue (e.g., clay) mineralogy in ironstone or channel iron deposits (CID) in the Pilbara region of Western Australia (e.g., Haest et al., 2012).

导论在过去的十年里,超声成象在科学与技术上都取得了巨大的进展。本文着重评述医学超声诊断发展的前沿,确认某些将来看起来更有前景的领域,并考虑某些在物理学和技术上同时出现的一些问题。我们并不企图涉及新的和正在出现的临床应用,然而值得注意的是新技术会导新的超声诊断,也就是说最终会决定临床的应用。

Apical ballooning syndrome (Takotsubo cardiomyopathy) is an increasingly recognized form of acute systolic dysfunction which is usually reversible. It typically occurs in post-menopausal women following a major psychological stressor. We conducted a single center, retrospective analysis of all hospitalized patients from 2001-2012 and found 104 patients who met the diagnostic criteria for apical ballooning. In this current largest series of its kind, 83% of the patients were women. Among both men and women, an antecedent stressor was not always identified. The exact pathophysiologic mechanism resulting in apical ballooning remains poorly understood. These findings challenge the paradigm that catecholamine cardiotoxicity in the setting of relative estrogen deficiency results in the cardiomyopathy.
