background: to determine the prevalence and characteristics of birth defects in perinatal infants in hubei province during 200l-2008. methods: the prevalence of birth defects in perinatal infants delivered after 28 weeks or more was analyzed in hubei surveillance hospitals during 200l-2008. results: the incidence of birth defects in perinatal infants from 200l to 2008 was 120.0 per 10,000 birth...

Objective- Current trends emphasize the acceleration of fracture healing on the ground that in doing so, the limitation of mobility and complications associated with recovery period are reduced. The present study aims to compare autogenic costal cartilage with Chitosan scaffold in canine humeral defect healing. Design- Experimental study Animal-15 adult male dogs Procedures-...

In this work, the formation of oxygen-vacancy defect in 3d metals-doped TiO2 anatase and rutile structures is first investigated. The systematic calculations of formation energy, crystalline stability, band structure and density of state (DOS) of TiO2 samples of anatase and rutile doped with 3d transition metals with and without oxygen defect is done using FHI-aims as a software package based o...

Recent indications of a neutrino mass raise the possibility that the dark matter may be hot, which would be a severe challenge for structure formation theory. We argue that generic defect theories fare very well in hot dark matter cosmologies, and also work in the presence of curvature or a cosmological constant. If this model is correct, then the MAP and PLANCK missions will not measure what p...

methylmalonic acidemia (mma) is usually caused by a deficiency of the enzyme methylmalonyl-coa mutase (mcm), a defect in the transport or synthesis of its cofactor, adenosyl-cobalamin (cbla, cblb, cblc, cblf, cbld, and cblx), or deficiency of the enzyme methylmalonyl-coa epimerase. a comprehensive diagnostic approach involves investigations of metabolites with tandem mass spectrometry, organic ...
