The label “Keynes-Negishi equilibria” is attached here to equilibria in a monetary economy with imperfectly competitive product and labor markets where business firms and labor unions hold demand perceptions with kinks as posited in Negishi’s 1979 book Microeconomic Foundations of Keynesian Macroeconomics. Such equilibria are defined in a general equilibrium model, and shown to exist. Methodolo...

The complication of Menkes disease (MD) and gastroesophageal reflux disease (GERD) is extremely rare. This report describes the very rare case of a one-year-old boy with MD complicated with GERD, and the successful surgical treatment of GERD. We review the literature on this relationship between MD and GERD, and discuss the clinical features of this association. Furthermore, the possible cause ...

Menkes disease is a rare neurodegenerative disorder caused by mutations in ATP7A gene. Deficiency in copper-dependent enzymes results in the unique kinky hair appearance, neurodegeneration, developmental delay, seizures, failure to thrive and other connective tissue or organ abnormalities. Other than biochemical tests, DNA-based diagnosis is now playing an important role. More than two hundred ...

Tricho-dento-osseous (TDO) syndrome is an autosomal dominant trait characterized by curly kinky hair at birth, enamel hypoplasia, taurodontism, thickening of cortical bones and variable expression of craniofacial morphology. Genetic studies have identified a 4-bp deletion in the DLX3 gene that is associated with TDO; however, phenotypic characterization and classification of TDO remains unclear...
