Is the predictive ability of serum alpha-fetoprotein for hepatocellular carcinoma linked with the characteristics of the target population at surveillance?
Serum AFP had a fairly stable predictive accuracy for HCC, with an optimal cutoff around 30 ng/ml. ALT level, viral status, and tumor size may significantly confound its ability to detect HCC.
A way to reduce detrimental effects of deep-fat frying is through operating-pressure reduction, the essence behind vacuum deep-fat frying. In this way, it is possible to remove product moisture at a low temperature in a low-oxygen environment. The objective of this research was to study the effect of oil temperature reduction when vacuum frying traditional (potatoes) and nontraditional products (carrots and apples) on most important quality attributes (vitamins, color, and oil uptake). Results are promising and show that vacuum frying can be an alternative to produce nutritious and novel snacks with desired quality attributes, since vitamins and color were greatly preserved and oil absorption could be substantially reduced.
