Dual-Functional Cross-Meandering Resonator for Power Frequency Electromagnetic Shielding and Wireless Sensing Communication.

The research on MEMS wireless sensing technology adapted to strong power frequency electromagnetic field environments is of great significance to our energy security, economic society, and even national security. Here, we propose a subwavelength cross-meandering resonator (0.49 × 0.

[High-aspect-ratio gas chromatography column based on micro-electro-mechanical system technology].

Miniaturization of gas chromatography (GC) columns is one of the key problems associated with microminiaturization of a chromatograph. In this study, a GC column with high-aspect-ratio microchannel based on micro-electro-mechanical system (MEMS) technology has been designed and manufactured. Simulation and analysis by the COMSOL software revealed that the GC column has even velocity field distribution, which is crucial for improving the separation efficiency of the column.

[Research progress of micro-electro-mechanical systems micro gas chromatography columns].

The gas chromatography (GC) column is a key component of the gas chromatographic system, which is mainly used for the separation of mixed gas components. Compared with the traditional GC column, the micro GC column based on micro-electro-mechanical systems (MEMS) technology has the advantages of lighter weight, smaller volume, lower power consumption, and faster analysis. Furthermore, it can be integrated into a portable instrument, such as a miniaturized GC.

Genetic characterization of measles viruses in China, 2004.

Genetic characterization of wild-type measles virus was studied using nucleotide sequencing of the C-terminal region of the N protein gene and phylogenetic analysis on 59 isolates from 16 provinces of China in 2004. The results showed that all of the isolates belonged to genotype H1. 51 isolates were belonged to cluster 1 and 8 isolates were cluster 2 and Viruses from both clusters were distributed throughout China without distinct geographic pattern.

[Human metapneumovirus infection in children with acute respiratory tract inflammation in Urumuqi].

Objective: To understand whether human metapneumovirus (hMPV) is one of the pathogens leading to the children's respiratory infections in Urumqi.

Methods: A total number of 209 samples were collected in the People's General Hospital of Xinjiang Uygur Autonomous Region from November 2006 to April 2007 with some from the hospitalized children, while the others from outpatient clinic. Specimens included nasopharyngeal aspirates (NPA) and swabs were analyzed.

Emerging G9 rotavirus strains in the northwest of China.

Although G9 rotaviruses have become one of the important rotavirus genotypes worldwide, they have been uncommon in China. Recently, we reported G9 rotaviruses as a highly prevalent genotype in Xinjiang, the northwest part of China [Yang, X., Matthijnssens, J.

Temporal changes of rotavirus strain distribution in a city in the northwest of China, 1996-2005.

Background: Very little is known about human rotaviruses in the northwest of China. To investigate the genomic diversity, we evaluated the distribution of rotavirus genotypes in this region covering a 10-year period (1996-2005).

Methods: Rotavirus antigen was detected in stool specimens by enzyme immunoassay (EIA), and G and P genotyping was performed by reverse transcription-polymerase chain reaction and nucleotide sequencing methods.

Molecular epidemiology of measles viruses in China, 1995-2003.

This report describes the genetic characterization of 297 wild-type measles viruses that were isolated in 24 provinces of China between 1995 and 2003. Phylogenetic analysis of the N gene sequences showed that all of the isolates belonged to genotype H1 except 3 isolates, which were genotype A. The nucleotide sequence and predicted amino acid homologies of the 294-genotype H1 strains were 94.

Evolutionary history and global spread of the emerging g12 human rotaviruses.

G12 rotaviruses were first detected in diarrheic children in the Philippines in 1987, but no further cases were reported until 1998. However, G12 rotaviruses have been detected all over the world in recent years. Here, we report the worldwide variations of G12 rotaviruses to investigate the evolutionary mechanisms by which they managed to spread globally in a short period of time.

G8 rotavirus strains isolated in the Democratic Republic of Congo belong to the DS-1-like genogroup.

Several G8P[6] and G8P[8] rotavirus strains were isolated from hospitalized patients in the Democratic Republic of Congo in 2003. To investigate their overall genomic relatedness and to determine to which genogroup they belonged, the complete genomes of strains DRC88 (G8P[8]) and DRC86 (G8P[6]) were determined. Genomic comparison of these two African G8 strains revealed that 10 out of their 11 gene segments, except for VP4, were nearly identical (>98.

Full genomic analysis of human rotavirus strain B4106 and lapine rotavirus strain 30/96 provides evidence for interspecies transmission.

The Belgian rotavirus strain B4106, isolated from a child with gastroenteritis, was previously found to have VP7 (G3), VP4 (P[14]), and NSP4 (A genotype) genes closely related to those of lapine rotaviruses, suggesting a possible lapine origin or natural reassortment of strain B4106. To investigate the origin of this unusual strain, the gene sequences encoding VP1, VP2, VP3, VP6, NSP1, NSP2, NSP3, and NSP5/6 were also determined. To allow comparison to a lapine strain, the 11 double-stranded RNA segments of a European G3P[14] rabbit rotavirus strain 30/96 were also determined.
