ABSTRACT
Liquid biopsy is a new noninvasive detection method and is also the main molecular detection method to guide the application of precision medicine. Liquid biopsy mainly includes the measurement of circulating free DNA (cf-DNA), circulating tumor cells, and exosomes, and in particular, cf-DNA is becoming a valuable molecular detection tool, especially in the early detection and diagnosis of liver cancer and parasitic infections involving the liver. This article reviews the clinical application of cf-DNA in liver cancer and liver-related parasitic diseases.
ABSTRACT
The structure of cancellous bone is cellular. There are two basic models of cancellous bone structure namely the model of rod-rod structure and the model of framework of perforated plate. This paper presents several models of structure developed from the model of rod-rod structure to the model of framework of perforated plate. We computed the elastic modulus of cancellous bone based on these modes using homogenization. The relationship between the elastic modulus(E) of cancellous bone and the apparent density(p) was determined to be E = 1.78rho1.88.
