Abstra t Di erentiated servi e approa h has been proposed as a potential solution to provide Quality of Servi es (QoS) in the next generation Internet. The ultimate goal of end-to-end servi e di erentiation an be a hieved by omplementing the network-level QoS with the servi e differentiation at the Internet servers. In this paper, we have presented a detailed study of the performan e of servi e...
‘Qingcui’ plum fruit becomes soft at harvesting. In this study, we assessed the effect of following different treatments on various texture parameters: three concentrations nitrogen (NH4NO3 0%, 0.5% and 1%) forms selenium (selenomethylcysteine [C5H9NO2SSe/SeMeCys], sodium selenate [Na2SeO4] sele-nomethionine [SeMet]). The parameters evaluated were fracture, hardness, cohesiveness, springiness, ...

Cardiovascular disease is recognized as an important clinical problem in radiotherapy and radiation protection. However, only few radiobiological models relevant for assessment of cardiotoxic effects of ionizing radiation are available. Here we describe the isolation of mouse primary cardiac endothelial cells, a possible target for cardiotoxic effects of radiation. Cells isolated from hearts of...
A specialized insulin was recently found in the venom of a fish-hunting cone snail, Conus geographus Here we show that many worm-hunting and snail-hunting cones also express venom insulins, and that this novel gene family has diversified explosively. Cone snails express a highly conserved insulin in their nerve ring; presumably this conventional signaling insulin is finely tuned to the Conus in...
Metabolic syndrome (MetS) is characterized by a cluster of cardiovascular risk factors that include: abdominal obesity, dyslipidaemia, hypertension, insulin resistance and impaired glucose tolerance. Recent genome wide association studies have identified several susceptibility regions involved in lipid metabolism that are also associated with MetS. We have explored the association of 9 genetic ...
Dermatitis herpetiformis (DH) is an autoimmune blistering skin disease associated with gluten-sensitive enteropathy (CD). In order to investigate the pathogenesis of skin lesions at molecular level, we analysed the gene expression profiles in skin biopsies from 6 CD patients with DH and 6 healthy controls using Affymetrix HG-U133A 2.0 arrays. 486 genes were differentially expressed in DH skin c...
We demonstrate the advantages of using Bayesian neural networks for image analysis. The Bayesian approa h provides onsistent way to do inferen e by ombining the eviden e from data to prior knowledge from the problem. A pra ti al problem with neural networks is to sele t the orre t omplexity for the model, i.e., the right number of hidden units or orre t regularization parameters. The Bayesian a...
Increased numbers of endothelial cells are observed in peripheral blood of cancer patients. These circulating endothelial cells (CECs) may contribute to the formation of blood vessels in the tumor or reflect vascular damage caused by treatment or tumor growth. Characterization of these cells may aid in the understanding of the angiogenic process and may provide biomarkers for treatment efficacy...
ABSTRACT Re ent work has made mu h of using semanti knowledge, derived in parti ular from domain ontologies, for improving text learning tasks. Semanti knowledge is assumed to apture more in-depth knowledge of the text domain in omparison with onventional statisti s-based methods that an only rely on more surfa e vo abulary-spe i hara teristi s of a data set. Therefore, using semanti knowledge ...
