Application of gallium nitride nanostructures and nitrogen doped carbon spheres as supports for the hydrogenation of cinnamaldehyde.
J. Nanosci. Nanotechnol. 13(7) , 4990-5, (2013) This paper reports on the synthesis and use of nanostructures of gallium nitride (GaN NSs) and nitrogen doped carbon spheres (NCSs) as support materials for the hydrogenation of cinnamaldehyde. This study provides the first investigation of GaN as a catalyst ... |

Structure of the key species in the enzymatic oxidation of methane to methanol.
Nature 518(7539) , 431-4, (2015) Methane monooxygenase (MMO) catalyses the O2-dependent conversion of methane to methanol in methanotrophic bacteria, thereby preventing the atmospheric egress of approximately one billion tons of this potent greenhouse gas annually. The key reaction cycle int... |

Investigation of NADH binding, hydride transfer, and NAD(+) dissociation during NADH oxidation by mitochondrial complex I using modified nicotinamide nucleotides.
Biochemistry 52(23) , 4048-55, (2013) NADH:ubiquinone oxidoreductase (complex I) is a complicated respiratory enzyme that conserves the energy from NADH oxidation, coupled to ubiquinone reduction, as a proton motive force across the mitochondrial inner membrane. During catalysis, NADH oxidation b... |

Direct and reversible hydrogenation of CO2 to formate by a bacterial carbon dioxide reductase.
Science 342(6164) , 1382-5, (2013) Storage and transportation of hydrogen is a major obstacle for its use as a fuel. An increasingly considered alternative for the direct handling of hydrogen is to use carbon dioxide (CO2) as an intermediate storage material. However, CO2 is thermodynamically ... |

Hydrogen-rich saline improves survival and neurological outcome after cardiac arrest and cardiopulmonary resuscitation in rats.
Anesth. Analg. 119(2) , 368-80, (2014) Sudden cardiac arrest is a leading cause of death worldwide. Three-fourths of cardiac arrest patients die before hospital discharge or experience significant neurological damage. Hydrogen-rich saline, a portable, easily administered, and safe means of deliver... |

Electrocardiographic differences between COPD patients evaluated for lung transplantation with and without pulmonary hypertension.
ACS Nano 9(2) , 1707-20, (2015) Pulmonary hypertension (PH) is an indicator of poor prognosis in COPD patients; particularly in those with mean pulmonary artery pressure ≥ 40 mm Hg. Electrocardiography (ECG) might be useful for screening of this condition.Retrospective study of COPD patient... |

The oxidative inactivation of FeFe hydrogenase reveals the flexibility of the H-cluster.
Nature Chemistry 6(4) , 336-42, (2014) Nature is a valuable source of inspiration in the design of catalysts, and various approaches are used to elucidate the mechanism of hydrogenases, the enzymes that oxidize or produce H2. In FeFe hydrogenases, H2 oxidation occurs at the H-cluster, and catalysi... |

Rationale and mechanism for the low photoinactivation rate of bacteria in plasma.
Proc. Natl. Acad. Sci. U. S. A. 111(1) , 33-8, (2014) The rate of bacterial photoinactivation in plasma by methylene blue (MB), especially for Gram-negative bacteria, has been reported to be lower, by about an order of magnitude, than the rate of inactivation in PBS and water solutions. This low inactivation rat... |
