Question: Question: Do traditional clinical risk assessment tools accurately predict coronary atherosclerotic plaque burden : a CT angiography study?
Answer: Coronary risk stratification using a risk factor only-based scheme is a weak discriminator of the overall atherosclerotic plaque burden in individual patients. Patients with little or no plaque might be subjected to lifelong drug therapy, whereas many others with substantial plaque might be undertreated or not treated at all.

Answer: no

Question: Question: Are fragile histidine triad gene alterations essential for hepatocellular carcinoma development in South Korea?
Answer: Aberrant FHIT transcripts were more common in HCC tissues as compared to non-cancerous liver tissues. However, Fhit expression was lost or reduced in a minor fraction of HCC tissues, while it was strongly expressed in non-cancerous liver tissues. Therefore, our study suggests that FHIT plays a role in relatively few HCC cases in South Korea.

Answer: no
