BACKGROUND AND AIMS Hepatocellular carcinoma (HCC) remains a leading cause of death by cancer worldwide. Computerized diagnosis systems relying on novel imaging markers gained significant importance in recent years. Our aim was to integrate a novel morphometric measurement--the fractal dimension (FD)--into an artificial neural network (ANN) designed to diagnose HCC. MATERIAL AND METHODS The s...

OBJECTIVE Neonatal jaundice is the most common condition that requires hospital admission and outpatient follow-up after discharge in neonates. The values of more than 17 mg/dL in term infants are accepted as neonatal significant hyperbilirubinemia. We aimed to define if there is any relationship between second trimester serum markers and neonatal severe hyperbilirubinemia to protect the neonat...

Although borderline isolated systolic hypertension (ISH), defined as a blood pressure of 140 to 159/ 90 mm Hg, is a proven cardiovascular risk factor, the major clinical trials on treatment of ISH have used a cutoff of 160 mm Hg. Moreover, no data exist on the cardiovascular modifications associated with borderline ISH. Therefore, we compared subjects with borderline ISH to subjects with diasto...
