Apoptosis, or programmed cell death, is a physiological form of cell death that is important for normal embryologic development and cell turnover in adult organisms. Cumulative evidence suggests that apoptosis can also be triggered in tissues without a high rate of cell turnover, including those within the central nervous system (CNS). In fact, a crucial(More)
Programmed cell death involves a complex and interrelated cascade of cysteine proteases termed caspases that are synthesized as inactive zymogens, which are proteolytically processed to active enzymes. Caspase-8 is an initiator caspase that becomes activated when Fas death receptor-Fas ligand (FasL) coupling on the cell surface leads to coalescence of a(More)
Current multi-operator image resizing methods succeed in generating impressive results by using image similarity measure to guide the resizing process. An optimal operation path is found in the resizing space. However, their slow resizing speed caused by inefficient computation strategy of the bidirectional patch matching becomes a drawback in practical(More)
In this paper, we survey recent approaches to blue-noise sampling and discuss their beneficial applications. We discuss the sampling algorithms that use points as sampling primitives and classify the sampling algorithms based on various aspects, e.g., the sampling domain and the type of algorithm. We demonstrate several well-known applications that can be(More)
Poly-ADP-ribosylation (PAR) of proteins by poly(ADP-ribose) polymerases (PARP) occurs after experimental traumatic brain injury (TBI) and modulates neurologic outcome. Several promising pharmacological PARP inhibitors have been developed for use in humans, but there is currently no clinically relevant means of monitoring treatment effects. We therefore used(More)
BACKGROUND Inappropriate use of prescribing pharmaceuticals, particularly injections, not only affects the quality of medical care, but also leads to an increase in medical expenses. Publicly reporting performance data of medical care is becoming a common health policy tool adopted to supervise medical quality. To our knowledge, few studies about public(More)
BACKGROUND The World Health Report 2000 stated that increased public financing for healthcare was an integral part of the efforts to achieve equity of access. In 2009, the Chinese government launched a three-year health reform program to achieve equity of access. Through this reform program, the government intended to increase its investment in primary(More)
BACKGROUND Lymph node metastasis (LNM) of gastric cancer is an important prognostic factor regarding long-term survival. But several imaging techniques which are commonly used in stomach cannot satisfactorily assess the gastric cancer lymph node status. They can not achieve both high sensitivity and specificity. As a kind of machine-learning methods,(More)
Testes-specific protease 50 (TSP50) is a potential cancer-associated gene that may be involved in human laryngocarcinoma. The present study aimed to investigate suppressive effects on the HEp2 human laryngocarcinoma cell line by transfection with TSP50-specific short hairpin RNA (shRNA). Western blot analysis was used to detect the expression levels of(More)
