The new MPEG-21 standard defines a multimedia framework to enable transparent and augmented use of multimedia resources across heterogeneous networks and devices used by different communities. In this paper, we incorporated the perceived motion energy (PME) model into the proposed MPEG-21 digital item adaptation framework for frame dropping in H.264 encoded(More)
BACKGROUND Cortactin is an important regulator involved in invasion and migration of tumor cells. Although the relationship between cortactin and tumor invasion has been reported, it lacks follow-up evidence to support the forecasting role of cortactin for HCC prognosis. The aim of this study was to determine whether cortactin detection combined with(More)
Liver fibrosis is characterized by an exacerbated accumulation of deposition of the extracellular matrix (ECM), and the activation of hepatic stellate cells (HSC) plays a pivotal role in the development of liver fibrosis. Periostin has been shown to regulate cell adhesion, proliferation, migration and apoptosis; however, the involvement of periostin and its(More)
Calcium channel blockers (CCBs) have been shown to improve clinical outcomes in atherosclerotic vascular disease. The mechanisms underlying the vasculoprotective effects of a third-generation calcium channel blocker, azelnidipine, are incompletely understood. We asked whether azelnidipine attenuates atherosclerosis in monkeys and mice beyond its blood(More)
The receptor for advanced glycation end products (RAGE) and the angiotensin II type I receptor (AT1R) have been separately linked to the pathogenesis of diabetic atherosclerosis. However, no prior study has addressed a linkage between RAGE and AT1R in diabetic atherogenesis. Therefore, we tested the hypothesis that upregulation of the ligand-RAGE axis via(More)
We developed a highly sensitive method to detect liver tissue stiffness with atomic force microscopy (AFM), and investigated the physical features of hepatocarcinogenesis. Wistar rats received weekly intraperitoneal injections of diethylnitrosamine (DEN) or saline (control) followed by a 2-week wash-out period. Liver samples were harvested at 10, 14, or 18(More)
Assembly language programming courses inevitably include the need to assess programs submitted by the students. However, the task of grading solutions to student programming exercises is laborious. This paper describes a system for the automatic assessment of assembly language programs. This assessment tool uses the MASM, a developing tool for assembly(More)
BACKGROUND/AIMS Pancreatic injury after blunt abdominal trauma is always associated with a high morbidity and mortality. The purpose of this study was to evaluate the effect of a grading-therapeutic strategy and to highlight various challenges in the management of blunt pancreatic injury. METHODOLOGY All cases of pancreatic injury after blunt abdominal(More)
Enterprise level software is implemented using multi-layer architecture. These layers are often implemented using decoupled solutions with millions of lines of code. Programmers often have to track and debug a function call from user interface layer to the data access layer while troubleshooting an issue. They have to inspect the code based on search(More)
This paper examines use of dynamic probabilistic networks (DPN) for human action recognition. The actions of lifting objects and walking in the room, sitting in the room and neutral standing pose were used for testing the classification. The research used the dynamic interrelation between various different regions of interest (ROI) on the human body (face,(More)
