Despite the well-known design principles of vascular systems, it is unclear whether the vascular arterial tree obeys some scaling constraints during normal growth and ageing in a given species. Based on the micro-computed tomography measurements of coronary arterial trees in mice at different ages (one week to more than eight months), we show a constant(More)
Although atherosclerosis has been widely investigated at carotid artery bifurcation, there is a lack of morphometric and hemodynamic data at different stages of the disease. The purpose of this study was to determine the lesion difference in patients with carotid artery disease compared with healthy control subjects. The three-dimensional (3D) geometry of(More)
Recently, zwitterionic materials have been developed as alternatives to PEG for prolonging the circulation time of nanoparticles without triggering immune responses. However, zwitterionic coatings also hindered the interactions between nanoparticles and tumor cells, leading to less efficient uptake of nanoparticles by cancer cells. Such effect significantly(More)
Purpose: to study the anti-tumor effect and corresponding mechanism of Xinghuayu injection. Methods: (1) anti-tumor effect: Kunming mice were inoculated with hepatoma H<inf>22</inf> cells, and then were divided into model group, three dose Xinghuayu injection group and positive group, drug administrate red intraperitoneally once a day. After 7 days, the(More)
Animal models are of importance to investigate basic mechanisms for ischemic heart failure (HF). The objective of the study was to create a rabbit model through multiple coronary artery ligations to investigate the postoperative structure-function remodeling of the left ventricle (LV) and coronary arterial trees. Here, we hypothesize that the interplay of(More)
