In the title compound, [Cd(C(10)H(16)O(4))(C(16)H(14)N(4))](n), the Cd(II) ion is six-coordinated in a distorted octa-hedral geometry by four carboxyl-ate O atoms from two sebacate ligands and two N atoms from the chelating 1,4-bis-(2-benzimidazol-yl)ethanebutane ligand. Neighboring Cd(II) ions are bridged by the sebacate ligands, forming a zigzag polymeric chain structure. The chains are furth...

tions of K+, and triple-barrelled microelectrodes measuring K pH and membrane potential m have provided Initial attempts to measure K+ activity (a K ) in vacuoles a major advance towards this goal ( Walker et al., 1995, of barley leaf epidermal cells using triple-barrelled K+1996). The incorporation of a pH-sensing barrel allows selective microelectrodes gave values that were only unequivocal a...

In order to further improve the biocompatibility of xylitol based poly(xylitol sebacate) (PXS) bioelastomer, a novel kind of amino acid based poly(xylitol glutamate sebacate) (PXGS) has been successfully prepared in this work by melt polycondensation of xylitol, N-Boc glutamic acid and sebacic acid. Differential scanning calorimetry (DSC) results indicated the glass-transition temperatures coul...

Biodegradable polymers are proposed as a potential solution to environmental problems related plastic pollution. Potential benefits have been suggested in applications such agricultural mulching and fishing gear, where there can be considerable difficulty recovering products from the environment at end of their service life. Biodegradation is complex process influenced by both properties materi...

BACKGROUND Optimal cell sources and scaffold-cell interactions remain unanswered questions for tissue engineering of heart valves. We assessed the effect of different protein precoatings on a single scaffold type (elastomeric poly (glycerol sebacate)) with a single cell source (endothelial progenitor cells). METHODS AND RESULTS Elastomeric poly (glycerol sebacate) scaffolds were precoated wit...

In this study, the feasibility of using copper oxide (CuO) as an interface for the coupling of liquid chromatography (LC) and Fourier-transform infrared (FTIR) spectroscopy was investigated. CuO exhibits low absorption in the 4000 to 1000 cm-1 FTIR spectral region. In addition, LC-FTIR using CuO as the interface was extended to the analysis of sample mixtures containing benzamide and dioctyl se...

A pharmacologically active agent was easily extracted by aqueous or organic solvents from laboratory plastic tubes (Falcon Blue Max) and has been chemically identified as bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate. This compound (approximately 12 micrograms per tube approximately 25 nmol) blocked 1,4-dihydropyridine-sensitive 45Ca2+ uptake into GH3 cells with an IC50 value of 3.6 microM, inh...
