EMBO reports (2009) 10, 689–693. doi:10.1038/embor.2009.136 Introduction At the recent Keystone Symposium on Chromatin Dynamics and Higher Order Organization, an emerging and expanded view of the chromatin landscape was apparent. Many reports connected the organization of individual nucleosomes and histone-modification domains with the spatial co-localization of genes and regulatory elements in...

We propose an experimentally feasible scheme to teleport an unkown quantum state onto the vibrational degree of freedom of a macroscopic mirror. The quantum channel between the two parties is established by exploiting radiation pressure effects.

Tissue-specific heterogeneity of endothelial cells, both structural and functional, plays a crucial role in physiologic as well as pathologic processes, including inflammation, autoimmune diseases and tumor metastasis. This heterogeneity primarily results from the differential expression of adhesion molecules that are involved in the interactions between endothelium and circulating immune cells...

Monoclonal antibody HT462 recognizes a human T-cell leukemia virus type I (HTLV-I)-associated Mr 52,000 glycoprotein (HA-gp52), which is found on the surface of HTLV-infected cells. Whether HA-gp52 is encoded by the virus or by the infected cells has not yet been established. Using monoclonal HT462 in a competitive binding assay, natural human antibodies specific for HA-gp52 were detected in 97...

Under fusogenic conditions, fluorescent dye redistributed from the outer monolayer leaflet of red blood cells (RBCs) to cells expressing glycophosphatidylinositol-anchored influenza virus hemagglutinin (GPI-HA) without transfer of aqueous dye. This suggests that hemifusion, but not full fusion, occurred (Kemble, G. W., T. Danieli, and J. M. White. 1994. Cell. 76:383-391). We extended the eviden...

The glycosaminoglycan hyaluronan (HA) modulates cell proliferation and migration, and it is involved in several human vascular pathologies including atherosclerosis and vascular restenosis. During intima layer thickening, HA increases dramatically in the neointima extracellular matrix. Aging is one of the major risk factors for the insurgence of vascular diseases, in which smooth muscle cells (...

Purpose. To evaluate the effects and mechanism of exogenous hyaluronate (HA) in promoting corneal wound healing. Methods. Human corneal epithelial cells (HCECs) were incubated with different concentrations of HA to evaluate their efficiency in promoting cell migration and their modulation of repair factors. After inducing hyperosmolar conditions, the cell morphologies, cell apoptosis, and expre...
