This paper addresses several key issues in the ArnetMiner system, which aims at extracting and mining academic social networks. Specifically, the system focuses on: 1) Extracting researcher profiles automatically from the Web; 2) Integrating the publication data into the network from existing digital libraries; 3) Modeling the entire academic network; and(More)
Parkinson's disease (PD) is a common neurodegenerative movement disorder. Whereas the majority of PD cases are sporadic, rare genetic defects have been linked to this prevalent movement disorder. Mutations in DJ-1 are associated with autosomal recessive early-onset PD. The exact biochemical function of DJ-1 has remained elusive. Here we report the(More)
Both homozygous (L166P, M26I, deletion) and heterozygous mutations (D149A, A104T) in the DJ-1 gene have been identified in Parkinson's disease (PD) patients. The biochemical function and subcellular localization of DJ-1 protein have not been clarified. To date the localization of DJ-1 protein has largely been described in studies over-expressing tagged DJ-1(More)
The increasing availability of expressed sequence tags (ESTs) in wheat (Triticum aestivum) and related cereals provides a valuable resource of non-anonymous DNA molecular markers. In this study, 300 primer pairs were designed from 265 wheat ESTs that contain microsatellites in order to develop new markers for wheat. Their level of transferability in eight(More)
We study a novel problem of social context summarization for Web documents. Traditional summarization research has focused on extracting informative sentences from standard documents. With the rapid growth of online social networks, abundant user generated content (e.g., comments) associated with the standard documents is available. Which parts in a(More)
The identification of rare monogenic forms of Parkinson's disease (PD) has provided tremendous insight into the molecular pathogenesis of this disorder. Heritable mutations in alpha-synuclein, parkin, DJ-1 and PINK1 cause familial forms of PD. In the more common sporadic form of PD, oxidative stress and derangements in mitochondrial complex-I function are(More)
Diversity Array Technology (DArT) markers were used to investigate the genetic diversity, population structure, and extent of linkage disequilibrium (LD) on a genome-wide level in Canadian barley (Hordeum vulgare L.). Approximately 1,000 DArT markers were polymorphic and scored with high confidence among a collection of 170 barley lines composed mostly of(More)
The identification of genetic mutations responsible for rare familial forms of Parkinson's disease (PD) have provided tremendous insight into the molecular pathogenesis of this disorder. Mutations in the DJ-1 gene cause autosomal recessive early onset PD in two European families. A Dutch kindred displays a large homozygous genomic deletion encompassing(More)
This study examined the epidemiology, antibiotic susceptibility, and serotype distribution of Streptococcus pneumoniae associated with invasive and noninvasive pneumococcal disease in children in China. A total of 451 clinical isolates from children (age, <5 years) were collected from 8 cities from January 2005 to December 2006, including 31 isolated from(More)
Bone marrow-derived stromal cells have engendered interest because of their therapeutic potential for promoting tissue vascularization and repair. When mononuclear cells isolated from mouse bone marrow were cultured in DMEM supplemented with 10% fetal bovine serum, cell populations arose that showed rapid proliferation and loss of contact inhibition. These(More)
