OBJECTIVE To evaluate the prevalence of vitamin D deficiency in pregnant women and their newborns in Beijing, China and the influence of vitamin D deficiency on birth size. DESIGN A cross-sectional study. SETTING Data were collected from pregnant women who delivered during April to May 2010 at 306 Hospital of PLA in Beijing, China. SUBJECTS(More)
Nontypable Haemophilus influenzae (NTHi) and Haemophilus haemolyticus exhibit different pathogenicities, but to date, there remains no definitive and reliable strategy for differentiating these strains. In this study, we evaluated matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) as a potential method for(More)
Nilsimsa algorithm plays an important role in the digest-based anti-spam technique. Based on the research about Nilsimsa digest, we propose an approach to publish and lookup for Nilsimsa digests inDHT: DHTnil. In this paper, we discuss DHTnil's publication and lookup algorithm in detail, and evaluate the effectiveness of DHTnil through simulation(More)
OBJECTIVE To determine the true community prevalence of human cystic (CE) and alveolar (AE) echinococcosis (hydatid disease) in a highly endemic region in Ningxia Hui, China, by detecting asymptomatic cases. METHODS Using hospital records and "AE-risk" landscape patterns we selected study communities predicted to be at risk of human echinococcosis in(More)
Campylobacter jejuni ICDCCJ07001 (HS:41, ST2993) was isolated from a Guillain-Barré syndrome (GBS) patient during a 36-case GBS outbreak triggered by C. jejuni infections in north China in 2007. Sequence analysis revealed that the ICDCCJ07001 genome consisted of 1,664,840 base pairs (bp) and one tetracycline resistance plasmid of 44,084 bp. The GC content(More)
BACKGROUND Acute lymphoblastic leukemia (ALL) is a common form of cancer in children. Currently, bone marrow biopsy is used for diagnosis. Noninvasive biomarkers for the early diagnosis of pediatric ALL are urgently needed. The aim of this study was to discover potential protein biomarkers for pediatric ALL. METHODS Ninety-four pediatric ALL patients and(More)
Many mobile applications such as games and social applications are emerging for mobile devices. These powerful applications consume more and more running time and energy. So they are badly confined by mobile device with limited resource. Since cloud infrastructure has great potential to benefit task execution, this paper presents SmartVirtCloud (SmartVC). A(More)
In this study, a whole-genome CombiMatrix Custom oligonucleotide tiling microarray with 90,000 probes covering six sequenced Helicobacter pylori (H. pylori) genomes was designed. This microarray was used to compare the genomic profiles of eight unsequenced strains isolated from patients with different gastroduodenal diseases in Heilongjiang province of(More)
OBJECTIVE To study the detailed nature of genomic microevolution during mixed infection with multiple Helicobacter pylori strains in an individual. DESIGN We sampled 18 isolates from a single biopsy from a patient with chronic gastritis and nephritis. Whole-genome sequencing was applied to these isolates, and statistical genetic tools were used to(More)
