Thermodynamic characterization of the interaction between the C-terminal domain of extracellular superoxide dismutase and heparin by isothermal titration calorimetry.

18 Oct 2009 Extracellular superoxide dismutase (ECSOD) interacts with heparin through its C-terminal domain. In this study we used isothermal titration calorimetry (ITC) to get detailed thermodynamic information about the interaction. We have shown that the ...

19F NMR studies of alpha-synuclein conformation and fibrillation.

13 Sep 2009 Fibrils of the intrinsically disordered protein alpha-synuclein are hallmarks of Parkinson's disease. The fluorescent dye thioflavin T is often used to characterize fibrillation, but this assay may not provide quantitative information about ...

Snapshots of the fluorosalinosporamide/20S complex offer mechanistic insights for fine tuning proteasome inhibition.

8 Sep 2009 Many marketed drugs contain fluorine, reflecting its ability to modulate a variety of biological responses. The unique 20S proteasome inhibition profile of fluorosalinosporamide compared to chlorinated anticancer agent salinosporamide A (NPI-0052) ...

Buffered platelet-rich plasma enhances mesenchymal stem cell proliferation and chondrogenic differentiation.

30 Aug 2009 The success of tissue engineering applications can potentially be dramatically improved with the addition of adjuncts that increase the proliferation and differentiation of progenitor or stem cells. Platelet-rich plasma (PRP) has recently emerged as ...

Evaluation of polycaprolactone scaffold degradation for 6 months in vitro and in vivo.

30 Aug 2009 The use of polycaprolactone (PCL) as a biomaterial, especially in the fields of drug delivery and tissue engineering, has enjoyed significant growth. Understanding how such a device or scaffold eventually degrades in vivo is paramount as the defect ...

In vitro degradation of a biodegradable polyurethane foam, based on 1,4-butanediisocyanate: a three-year study at physiological and elevated temperature.

30 Aug 2009 Biodegradable polyesterurethanes (PUs) may be used as scaffold materials for tissue regeneration applications, because of their excellent mechanical properties. In this study, the degradation of highly porous PU foams was evaluated in vitro. The PU ...

Accelerated oxidation of epinephrine by silica nanoparticles.

30 Aug 2009 We have measured the influence of mesoporous silica (MCM-41 and SBA-15) nanoparticles and dense silica nanoparticles on epinephrine oxidation, a pH-dependent reaction, whose rate is small in acidic or neutral solutions but much greater at higher pH. ...

Dose effect of dual delivery of vascular endothelial growth factor and bone morphogenetic protein-2 on bone regeneration in a rat critical-size defect model.

30 Aug 2009 The dose effect of dual delivery of vascular endothelial growth factor (VEGF) and bone morphogenetic protein-2 (BMP-2) on bone regeneration was investigated in a rat cranial critical-size defect (CSD). It was hypothesized that decreasing amounts of ...

Nanoreactors for pH controlled sequential activity switching in multistep enzymatic processes.

30 Aug 2009 This theoretical model predicts that the activity of multiple enzymes may be controlled simultaneously with superior efficiency in nanosized reactors by adjusting pH. Multistep enzymatic processes employed for various purposes including organic ...

Modeling of the modulation by buffers of Ca2+ release through clusters of IP3 receptors.

17 Aug 2009 Intracellular Ca(2+) release is a versatile second messenger system. It is modeled here by reaction-diffusion equations for the free Ca(2+) and Ca(2+) buffers, with spatially discrete clusters of stochastic IP(3) receptor channels (IP(3)Rs) ...
