1沉积物粒径趋势与海洋沉积动力学显示文摘沉积物粒度数据除可用来识别沉积环境的类型或判定物质运动方式之外,还可用于海洋环境中沉积物输运方向的研究,即将沉积物净输运方向与粒度参数的空间变化(粒径趋势)相联系。利用粒径趋势分析,可根据粒度参数的平面分布图式定义粒径趋势矢量,进而将趋势矢量转换为沉积物净输运图像。粒径趋势分析的基本假设是,沿着净输运方向,某种粒径趋势出现的概率远高于其在别的方向上出现的概率。初步研究表明这个假设是成立的,但今后还需要从物理原理上说明粒径趋势与颗粒态物质运动的关系,从水槽实验和数学模型实验入手,进一步完善这一分析方法。以促进粒度特征研究乃至颗粒态物质动力学的进步。高抒 Michael Collins 1998中国科学基金1998,12,4:59
2The hypoxia-inducible factor-1α activates ectopic production of fibroblast growth factor 23 in tumor-induced osteomalacia显示文摘Tumor-induced osteomalacia(TIO) is a rare paraneoplastic syndrome in which ectopic production of fibroblast growth factor 23(FGF23) by non-malignant mesenchymal tumors causes phosphate wasting and bone fractures. Recent studies have implicated the hypoxia-inducible factor-1α(HIF-1α) in other phosphate wasting disorders caused by elevated FGF23, including X-linked hypophosphatemic rickets and autosomal dominant hypophosphatemia. Here we provide evidence that HIF-1α mediates aberrant FGF23 in TIO by transcriptionally activating its promoter. Immunohistochemical studies in phosphaturic mesenchymal tumors resected from patients with documented TIO showed that HIF-1α and FGF23 were co-localized in spindleshaped cells adjacent to blood vessels. Cultured tumor tissue produced high levels of intact FGF23 and demonstrated increased expression of HIF-1α protein. Transfection of MC3T3-E1 and Saos-2 cells with a HIF-1α expression construct induced the activity of a FGF23 reporter construct. Prior treatment of tumor organ cultures with HIF-1α inhibitors decreased HIF-1α and FGF23 protein accumulation and inhibited HIF-1α-induced luciferase reporter activity in transfected cells. Chromatin immunoprecipitation assays confirmed binding to a HIF-1α consensus sequence within the proximal FGF23 promoter, which was eliminated by treatment with a HIF-1α inhibitor. These results show for the first time that HIF-1α is a direct transcriptional activator of FGF23 and suggest that upregulation of HIF-1α activity in TIO contributes to the aberrant FGF23 production in these patients.Qian Zhang Michele Doucet Ryan E Tomlinson Xiaobin Han L Darryl Quarles Michael T Collins Thomas L Clemens 2016Bone Research2016,4,2:6
