Aims. We present the spectra of 36 Supernovae (SNe) of various types, obtained by the European Supernova Collaboration. Because of the spectral classification and the phase determination at their discovery the SNe did not warrant further study, and the spectra we present are the only available for the respective objects. In this paper we present and discuss this material using a new software fo...
The Drosophila extra sex combs (esc) protein, a member of the Polycomb group (PcG), is a transcriptional repressor of homeotic genes. Genetic studies have shown that esc protein is required in early embryos at about the time that other PcG proteins become engaged in homeotic gene repression. The esc protein consists primarily of multiple copies of the WD repeat, a motif that has been implicated...
Background: Mesenchymal stem cells (MSCs) are important candidates for MSC-based cellular therapy. Current paradigm states that MSCs support local progenitor cells in damaged tissue through paracrine signaling. Therefore, study of paracrine effects and secretome of MSCs could lead to the appreciation of mechanisms and molecules associated with the therapeutic effects of these cells. This study ...
normal 0 false false false en-us x-none ar-sa background: p revious studies confirmed that neural gene expression in embryonic stem cells (esc) could influence by chemical compounds through stimulating apoptotic pathway. we aimed to use escs-derived neural cells by embryoid body formation as an in vitro model for determination of neural gene expression changes in groups that treated by sera fro...
Neisseria gonorrhoeae strains displaying reduced susceptibility and resistance to extended-spectrum cephalosporins (ESCs) are major public health concerns. Although resistance mechanisms of ESCs have extensively been studied, the proteome-wide investigation on the biological response to the antibiotic stress is still limited. Herein, a proteomics approach based on two-dimensional gel electropho...
For example, the escape sequence "ESC 2/4 2/8 4/3" or "ESC $ ( C" indicates that the bytes following the escape sequence are Korean KSC characters, which are encoded in two bytes each. The escape sequence "ESC 2/14 4/1" or "ESC . A" indicates that ISO 8859-1 is designated to G2. After the designation, the single shifted sequence "ESC 4/14 4/1" or "ESC N A" is interpreted to represent a characte...
In this report, we demonstrate that an optic cup structure can form by self-organization in human ESC culture. The human ESC-derived optic cup is much larger than the mouse ESC-derived one, presumably reflecting the species differences. The neural retina in human ESC culture is thick and spontaneously curves in an apically convex manner, which is not seen in mouse ESC culture. In addition, huma...
The extra sex combs (esc) and Enhancer of zeste [E(z)] proteins are members of the Drosophila Polycomb group (Pc-G) of transcriptional repressors. Here we present evidence for direct physical interaction between the esc and E(z) proteins using yeast two-hybrid and in vitro binding assays. In addition, coimmunoprecipitation from embryo extracts demonstrates association of esc and E(z) in vivo. W...
