Organ-on-a-chip mimics heart’s biomechanical properties
Organ-on-a-chip mimics heart biomechanical properties

2017/3/14
The human heart beats more than 2.5 billion times in an average lifetime. Now scientists at Vanderbilt University have created a three-dimensional organ-on-a-chip that can mimic the heart’s amazing bi...
Solution Properties of Synthetic Chlorophyllide-and Bacteriochlorophyllide-apomyoglobin Complexes
Solution Properties Chlorophyllide Bacteriochlorophyllide apomyoglobin Complexes

2016/5/20
Well-defined 1:1 complexes have been formed between apomyoglobin (apoMb) and a number of chlorophyllide derivatives. The chlorophyllides substitute for heme in the pocket of myoglobin. These include m...
Numerical study of linear and circular model DNA chains confined in a slit: metric and topological properties

2012/4/20
Advanced Monte Carlo simulations are used to study the effect of nano-slit confinement on metric and topological properties of model DNA chains. We consider both linear and circularised chains with co...
Photochemical and photophysical properties of carotenoid immobilized on a surfactant micellar medium including chlorophyll as an artificial photosynthesis system
Artificial photosynthesis Carotenoid Crocetin Light-harvesting Mg chlorophyll-a, b Photo-protection

2010/12/2
To develop an artificial photosynthesis model, the anionic water-soluble carotenoid dye crocetin was electrostatically immobilized onto the surface of cationic surfactant cetyltrimethylammonium bromid...
Roles of charged residues in pH-dependent redox properties of cytochrome c3 from Desulfovibrio vulgaris Miyazaki F
tetraheme protein nuclear magnetic resonance (NMR) site-directed mutagenesis electron transfer hydrogenase

2010/12/2
Complicated pH-properties of the tetraheme cytochrome c3 (cyt c3) from Desulfovibrio vulgaris Miyazaki F (DvMF) were examined by the pH titrations of 1H-15N HSQC spectra in the ferric and ferrous stat...
Mechanism of muscle contraction based on stochastic properties of single actomyosin motors observed in vitro
