Rebalancing China’s economic growth: some insights from Japan’s experience
One of the greatest challenges China faces is how to reshape its heavily investment-driven mode of economic growth. By investigating how the rebalancing of Japan’s economic growth mode was realized in the 1970s, we indicate that it is essential in the rebalancing to correct the distortions in the factor cost (labor cost and capital cost) in a harmonious way. In addition, we refer to Japan’s experience to indicate that achieving domestic rebalancing does not necessarily lead to external rebalancing.China; Japan; Rebalancing; Factor Cost Distortion; Current Account Imbalance

Gene Deletion Algorithms for Minimum Reaction Network Design by Mixed-Integer Linear Programming for Metabolite Production in Constraint-Based Models: gDel_minRN
Genome-scale constraint-based metabolic networks play an important role in the simulation of growth-coupled production, which means that cell growth and target metabolite production are simultaneously achieved. For growth-coupled production, a minimal reaction-network-based design is known to be effective. However, the obtained reaction networks often fail to be realized by gene deletions due to conflicts with gene-protein-reaction (GPR) relations. Here, we developed gDel_minRN that determines gene deletion strategies using mixed-integer linear programming to achieve growth-coupled production by repressing the maximum number of reactions via GPR relations. The results of computational experiments showed that gDel_minRN could determine the core parts, which include only 30% to 55% of whole genes, for stoichiometrically feasible growth-coupled production for many target metabolites, which include useful vitamins such as biotin (vitamin B7), riboflavin (vitamin B2), and pantothenate (vitamin B5). Since gDel_minRN calculates a constraint-based model of the minimum number of gene-associated reactions without conflict with GPR relations, it helps biological analysis of the core parts essential for growth-coupled production for each target metabolite. The source codes, implemented in MATLAB using CPLEX and COBRA Toolbox, are available on https://github.com/MetNetComp/gDel-minRN
<CLINICAL REPORT>A case of inverted papilloma of the maxillary sinus
A case of inverted papilloma arising in the maxillary sinus is described. The first symptoms were rhinorroea and discomfort of the left infraorbital region. A biopsy obtained by penetration into the maxillary sinus resulted in a diagnosis of chronic sinusitis. However, the surgical specimen showed characteristic inverted epithelial proliferation. Two years after operation by the Caldwell-Luc method, there are no signs of recurrence. The diagnosis and treatment of inverted papilloma are discussed
