Lymphedema is mainly caused by lymphatic obstruction and manifested as tissue swelling, often in the arms and legs. Lymphedema is one of the most common post-surgical complications in breast cancer patients and presents a painful and disfiguring chronic illness that has few treatment options. Here, we evaluated the therapeutic potential of interleukin(More)
Lymphatic endothelial cells (LECs) are differentiated from blood vascular endothelial cells (BECs) during embryogenesis and this physiological cell fate specification is controlled by PROX1, the master regulator for lymphatic development. When Kaposi sarcoma herpes virus (KSHV) infects host cells, it activates the otherwise silenced embryonic endothelial(More)
Does entrepreneurship cause urban economic growth and if so how large is the impact? Empirical analysis of such question is hampered by endogeneity. This paper uses two different sets of variables – the homestead exemption levels in state bankruptcy laws from 1975 and the share of MSA overlaying aquifers-to instrument for entrepreneurship and examine urban(More)
Concerns about the quality of state-financed nursing home care has led to the wide-scale adoption by states of pass-through subsidies, in which Medicaid reimbursement rates are directly tied to staffing expenditure. We examine the effects of Medicaid pass-through on nursing home staffing and quality of care by adapting a two-step FGLS method that addresses(More)
This paper examines how education policy generates residential sorting and changes residential land price inequality within a city. In 1974, Seoul shifted away from an exam based high school admission system, created high school districts and randomly allocated students to schools within each district. Furthermore, the city government relocated South(More)
This paper examines how student assignment rules impact intergenerational mobility. High school admission had traditionally been exam based in South Korea. However, between 1974 and 1980 the central government shifted several cities to a school district based admission system. I estimate the impact of this reform on the intergenerational income elasticity.(More)
This paper examines how an autocratic regime domestically counters the impact of economic sanctions. A stylized model predicts that, as long as non-compliance is not too costly, the autocrat redistributes resources to the more valuable urban area when sanctions increase. Empirically, I examine the case of North Korea. I use the satellite night lights data(More)
The field of reconstructive microsurgery is experiencing tremendous growth, as evidenced by recent advances in face and hand transplantation, lower limb salvage after trauma, and breast reconstruction. Common to all of these procedures is the creation of a nutrient vascular supply by microsurgical anastomosis between a single artery and vein. Complications(More)
PURPOSE The purpose of this study was to investigate the effects of transplantation of an in vitro-generated, scaffold-free, tissue-engineered cartilage tissue analogue (CTA) using a suspension chondrocyte culture in a rabbit growth-arrest model. MATERIALS AND METHODS We harvested cartilage cells from the articular cartilage of the joints of white rabbits(More)
This paper examines the impact of sanctions on trade, and how international relations influences the welfare implications of sanctions. Sanctions intend to punish target countries by inhibiting them from the gains from trade. The e↵ect of sanctions depends on not only the bilateral impact on trade but how much trade is diverted to other countries. I(More)
