Determining the composition and function of subgingival dental plaque is crucial to understanding human periodontal health and disease, but it is challenging because of the complexity of the interactions between human microbiomes and human body. Here, we examined the phylogenetic and functional gene differences between periodontal and healthy individuals(More)
INTRODUCTION Hepatocyte growth factor (HGF) is a multifunctional cytokine that is able to stimulate multiple intracellular signaling pathways to induce a remarkable variety of biological activities in a wide spectrum of cell types. The functions of HGF in modulating diverse biological responses in mesenchymal stem cells have been reported, and our previous(More)
The O + O2 isotope exchange reactions play an important role in determining the oxygen isotopic composition of a number of trace gases in the atmosphere, and their temperature dependence and kinetic isotope effects (KIEs) provide important constraints on our understanding of the origin and mechanism of these and other unusual oxygen KIEs important in the(More)
The title isotope exchange reaction was studied by converged time-dependent wave packet calculations, where an efficient 4th order split operator was applied to propagate the initial wave packet. State-to-state differential and integral cross sections up to the collision energy of 0.35 eV were obtained with (32)O2 in the hypothetical j0 = 0 state. It is(More)
