Mobile IPv6 (MIPv6) is proposed to enable network applications to continuously operate at the required quality of service in the wire or wireless IP network. Handover latency of MIPv6 is the main cause of packet loss and performance degradation and is too long for real-time and throughput-sensitive applications. Enhancement of basic MIPv6 with respect to(More)
The objective of this study was to develop anatomically correct whole body human models of an adult male (34 years old), an adult female (26 years old) and two children (an 11-year-old girl and a six-year-old boy) for the optimized evaluation of electromagnetic exposure. These four models are referred to as the Virtual Family. They are based on high(More)
Neural impairments accompanying chronic obstructive pulmonary disease (COPD) have received growing research attention. Previous neuroimaging studies exclusively used volumetric methods to measure cortical volume as a whole rather than focusing on anatomical and neuropathological distinct indices. Here we decomposed the cortical architecture into cortical(More)
miRNAs have emerged as post-transcriptional regulators that are critically involved in the pathogenesis of a number of human cancers. Cdc42, one of the best characterized members of the Rho GTPase family, is found to be up-regulated in several types of human tumors and has been implicated in cancer initiation and progression. In the present study, we have(More)
Flavonoids, a group of natural compounds found in a variety of vegetables and herbal medicines, have been intensively reported on regarding their estrogen-like activities and particularly their ability to affect bone metabolism. Here, different subclasses of flavonoids were screened for their osteogenic properties by measuring alkaline phosphatase activity(More)
Cell-released microvesicles (MVs) represent a novel way of cell-to-cell communication. Previous evidence indicates that endothelial progenitor cells (EPCs)-derived MVs can modulate endothelial cell survival and proliferation. In this study, we evaluated whether EPC-MVs protect cardiomyocytes (CMs) against angiotensin II (Ang II)-induced hypertrophy and(More)
Porcine reproductive and respiratory syndrome virus (PRRSV), a member of the Arteriviridae family of Nidovirales, is the causative agent of porcine reproductive and respiratory syndrome, which results in enormous economic losses in the swine industry. As the second protein encoded by the PRRSV genome, nsp1beta cleaves itself from the downstream nsp2 protein(More)
BACKGROUND D-ribose in cells and human serum participates in glycation of proteins resulting in advanced glycation end products (AGEs) that affect cell metabolism and induce cell death. However, the mechanism by which D-ribose-glycated proteins induce cell death is still unclear. RESULTS Here, we incubated D-ribose with bovine serum albumin (BSA) and(More)
Ginsenoside Rg1 has been reported to improve cognitive function in many memory-impaired animal models. However, little is known about the bioactivity of its metabolites in the central nervous system in vivo. In the present study, we employed the step through test and electrophysiological approach to investigate the effects of ginsenoside Rg1's primary(More)
In this paper, we apply a Bag-of-Features approach to malignant melanoma detection based on epiluminescence microscopy imaging. Each skin lesion is represented by a histogram of codewords or clusters identified from a training data set. Classification results using Naive Bayes classification and Support Vector Machines are reported. The best performance(More)
