Synthesis and some properties of binuclear ruthenocene derivatives bridged by both ethene and thiophene derivatives

http://www.sciencedirect.com/science/journal/0022328X | http://www.sciencedirect.com/science/journal/0022328XBinuclear ruthenocenes bridged by ethenes and thiophene derivatives, Rc-CH=CH-Z-Rc and Rc*-CH=CH-Z-CH=CH-Rc* (Z = thiophene, thieno[3,2-b]thiophene, and 2,2’-bithiophene; Rc = ruthenocenyl, R* = 1’,2’,3’,4’,5’-pentamethylruthenocenyl) were prepared. These complexes showed a one-step two-electron redox wave in the cyclic voltammograms, in contrast to the benzenoid-bridged dinuclear ruthenocenes. The chemical oxidation of the Rc-CH=CH-Z-Rc complexes gave no stable oxidized species. The two-electron oxidized species of the Rc*-CH=CH-Z-CH=CH-Rc* complexes were comparably stable and contained a fulvene-complex type structure.textapplication/pdfjournal articl

In Vitro Developmental Model of the Gastrointestinal Tract from Mouse Embryonic Stem Cells

2007-10Mouse embryonic stem (ES) cells are pluripotent and retain their potential to form cells, tissues and organs originated from three embryonic germ layers. Recently, we developed in vitro organ -gut‐like structures- from mouse ES cells. They had basically similar morphological features to a mouse gastrointestinal tract in vivo composed of three distinct layers (i.e., epithelium, connective tissue and musculature). Gut‐like structures showed spontaneous contractions derived from pacemaker cells (interstitial cells of Cajal) in the musculature. We also examined their formation process and expression pattern of transcription factors crucial for gut organogenesis such as Id2, Sox17, HNF3β/Foxa2 and GATA4. We found that they mimic the development of embryonic gut in vivo and showed a similar expression pattern of common transcription factors. They also maintain their developmental potential after transplantation to a renal capsule. Therefore, gut‐like structures are suitable for in vitro models of gastrointestinal tracts and their development. In addition, we pointed out several unique features different from gut in vivo that provide useful and advantageous tools to investigate the developmental mechanism of the gastrointestinal tract.departmental bulletin pape

Immunostaining and densitometric quantification of HNE(A) and HO-1 (B) in pyramidal neurons in old (25–30 month-old) mice shows that these oxidative stress markers tend to increase slightly with APP/Aβ expression, although levels are not affected by reduction of Sod2 activity.

High magnification images of the double immunofluorescence staining in the hippocampus of Sod2^+/−, hAPP/Sod2^+/+, and hAPP/Sod2^+/− mice at 25–30 months of age using antibodies against GFAP (Green fluorescence), HNE (Red fluorescence in A), and HO-1 (Red fluorescence in B).

<p>In Sod2^+/− mice there is a moderate level of astrocytic (GFAP) staining, and moderate levels of HNE (A) or HO-1 (B) localized to glial cells (Merged images). In hAPP/Sod2^+/+ and hAPP/Sod2^+/− mice there is extensive plaque formation (Asterisk), striking increases in levels of glial HNE(A), and HO-1 (B) relative to mice without hAPP/Aβ expression. The magnification is 20×.</p
