For the complete biodegradation of a mixture of benzene, toluene, and p-xylene (BTX), a critical metabolic step that can connect two existing metabolic pathways of aromatic compounds (the tod and the tol pathways) was determined. Toluate-cis-glycol dehydrogenase in the tol pathway was found to attack benzene-cis-glycol, toluene-cis-glycol, and(More)
The tumor suppressor p53 is often inactivated in head and neck cancer (HNC) through TP53 mutations or overexpression of mouse double minute 2 or mouse double minute X. Restoration of p53 function by counteracting these p53 repressors is a promising strategy for cancer treatment. The present study assessed the ability of a heat shock protein 90 (Hsp90)(More)
BACKGROUND To achieve a more reliable way of transplanting cardiomyocytes, we conducted an autologous cardiomyocyte transplantation using a biodegradable scaffold, instead of a syringe injection, as a vehicle for transporting cells in an ovine myocardial infarction model. MATERIALS AND METHODS A myocardial infarction was created in sheep using sequential(More)
The moving actuator type total artificial heart (TAH) developed in the Seoul National University has numerous design improvements based upon the digital signal processor (DSP). These improvements include the implantability of all electronics, an automatic control algorithm, and extension of the battery run-time in connection with an amorphous silicon solar(More)
Two cases of primary intimal fibroplasia of the renal artery with renovascular hypertension are described. Case 1 was 27 year old female who was incidentally found to have blood pressure of 210/130 mmHg on routine physical examination. Renal arteriogram revealed tubular narrowing of the mid protion of the left renal artery. Both patients showed(More)
