Human Embryonic Stem Cell-Derived and Fetal Macrophages Exhibit Mainly Features of Alternative (M2) Polarization.
2009
Abstract Abstract 4598 Monocyte heterogeneity has long been recognized and 2 functional subsets of human monocytes that exert specific roles in homeostasis and inflammation in vivo, M1 and M2 monocytes, has been described. The different monocyte subsets seem to reflect developmental stages with distinct physiological roles but few is known whether the macrophage diversity arises in early ontogeny. Human embryonic stem cells (hESC) provide an unique model for in vitro studies of the early ontogeny of the hematopoietic system. Human embryonic monocytes were obtained from embryoid bodies cultured for 3 weeks in the presence of BMP4, VEGF and a mixture of hematopoietic cytokines. The sorted CD1…
A Metaphor for Identities in Transition through Urbanization and Globalization: Tofu and One Hundred Surnames
2019
The Chinese artist Chen Qiulin has been taking displacement and the resulting unrest in people’s identity as her persistent theme since the early 1990s. Focusing on a series of her works made since 2004 dealing explicitly with tofu and Chinese surnames, this paper examines her exploration of identities in transition in the context of China’s mass urbanization and globalization. By showing the artist’s conceptual evolution, her preference for materials and mediums, and her exhibition strategy, this paper explores two issues. First, it illuminates how the artist has transformed “tofu” and “surname” into a metaphor for the dilemma of identity under the urbanization in China. Second, it discuss…
Rising Ecological Awareness in Chinese Contemporary Art : An Analysis of the Cultural Environment
2016
The past three decades have witnessed an unprecedented ecological crisis in China; however, there has been very little study of ecological concern in Chinese contemporary art. Ecological awareness has emerged in Chinese contemporary art since the early 1990s. This paper explores the various cultural factors that are involved. First, the rising ecological awareness in Chinese art in the 1990s is a corollary of ideological changes, both in social politics and in art. Chinese contemporary art in the 1990s experienced a constantly ongoing social turn to counter the dominance of the market and to continue the critical spirit. When this inner need in Chinese contemporary art encountered the thoro…
Production, isolation and characterization of radiochemically pure 163Ho samples for the ECHo-project
2018
Abstract Several experiments on the study of the electron neutrino mass are based on high-statistics measurements of the energy spectrum following electron capture of the radionuclide 163Ho. They rely on the availability of large, radiochemically pure samples of 163Ho. Here, we describe the production, separation, characterization, and sample production within the Electron Capture in Holmium-163 (ECHo) project. 163Ho has been produced by thermal neutron activation of enriched, prepurified 162Er targets in the high flux reactor of the Institut Laue-Langevin, Grenoble, France, in irradiations lasting up to 54 days. Irradiated targets were chemically processed by means of extraction chromatogr…
Un estudio del contenido científico de las preguntas formuladas por estudiantes cuando intentan comprender dispositivos experimentales
2013
RESUMEN: Se muestra un análisis descriptivo del contenido científico de las preguntas formuladas por estudiantes de secundaria y universitarios, cuando tratan de comprender el funcionamiento de dispositivos experimentales. Se consideran tres situaciones didácticas habituales: leer un texto acompañado de imágenes estáticas (esquemáticas); visualizar imágenes dinámicas (video o demostración de cátedra), observar y manipular los dispositivos. Solo una tercera parte de las preguntas de los estudiantes contuvieron algún término científico, aunque los universitarios superaron claramente a los de secundaria. Las leyes y principios científicos, necesarios para modelizar y explicar la realidad, apen…
A Lebesgue-type decomposition for non-positive sesquilinear forms
2018
A Lebesgue-type decomposition of a (non necessarily non-negative) sesquilinear form with respect to a non-negative one is studied. This decomposition consists of a sum of three parts: two are dominated by an absolutely continuous form and a singular non-negative one, respectively, and the latter is majorized by the product of an absolutely continuous and a singular non-negative forms. The Lebesgue decomposition of a complex measure is given as application.
