Polyacrylamide hydrogel (PAAG) as an implanted material for augmentation mammaplasty has been used for years in China. Many kinds of complications associated with PAAG use have been reported in the clinical literature. This report presents two cases of breast cancer occurring after injection of PAAG in augmented breasts. The delayed diagnosis and more(More)
We assess the potential impact for non-high-income countries (NHICs) of linking bank capital asset requirements (CARs) to private sector ratings-as contemplated by the new Basel proposal. Specifically, we show that linking bank CARs to external ratings would have a series of undesirable effects for NHICs. First, since ratings are by far less widespread for(More)
We provide a firm level analysis of the impact of capital market liberalization in 18 emerging markets. We find a larger increase in returns during liberalization and a larger decrease in returns after liberalization than previously found using indexes. While slightly more than half of the firms had higher returns during liberalization, a significant(More)
What is the information content of firm ratings? We disentangle the relative contribution to firms' ratings of sovereign risks and individual firms' performance indicators, reportedly employed by rating agencies. We reach three conclusions. First, sovereign risks' contribution is disproportionately greater in developing countries vis-à-vis developed(More)
In this paper, we propose an image driven shape deformation approach for stylizing a 3D mesh using styles learned from existing 2D illustrations. Our approach models a 2D illustration as a planar mesh and represents the shape styles with four components: the object contour, the context curves, user-specified features and local shape details. After the(More)
The Research Paper Series primarily disseminates selected work in progress to facilitate an exchange of ideas within the Institute's constituencies and the wider academic and policy communities.

OBJECTIVE To improve the technique of prominent malar complex reduction. METHODS The improvements of the operation procedure included double-oblique osteotomy of the prominent malar complex, accessorial tiny preauricular incision and the way that the complex was moved upward, inward or posteriorly. The zygomatic body was fixed with microplate screw or(More)
There is ample evidence indicating that epicardial adipose tissue (EAT) volume and thickness is positively associated with coronary artery disease (CAD). However, the exact pathological changes in the human EAT after myocardial ischemia remains largely unclear. In the current study, we applied a comparative quantitative proteomics to elucidate the altered(More)
