Human coronavirus (HCoV) is one of the most common causes of respiratory tract infection throughout the world. To investigate the epidemiological and genetic variation of HCoV in Guangzhou, south China, we collected totally 13048 throat and nasal swab specimens from adults and children with fever and acute upper respiratory infection symptoms in Gunazhou, south China between July 2010 and June ...

BACKGROUND AND OBJECTIVE Blood-borne infections, such as the HIV virus and hepatitis B and C, are major problems in patients receiving blood products. Here we examined the prevalence of HTLV-1, HCV, HBV, and HIV in hemophilic patients. METHODS A cross-sectional study on 108 hemophilic patients (101 males and 7 females) involved detection of HBV, HCV, HIV and HTLV-1 infections using immunoassa...

Brucellosis is a serious public health problem in Ulanqab, which is a region located in the middle of the Inner Mongolia Autonomous Region adjacent to Shanxi and Hebei provinces. The disease is prevalent in both the latter provinces and Ulanqab with the highest prevalence of brucellosis occurring in Inner Mongolia. The MLVA-16 scheme is a genotyping tool for assessing genetic diversity and rela...

For the first time the cross-correlation between type Ia supernova host galaxies and surrounding field galaxies is measured using the Supernova Legacy Survey sample. Over the z=0.2 to 0.9 redshift range we find that supernova hosts are correlated an average of 60% more strongly than similarly selected field galaxies over the 3−100′′ range and about a factor of 3 more strongly below 10. The corr...

The atmosphere of the extremely high-velocity (530 − 920 km s) early B-type star HD271791 is enriched in α-process elements, which suggests that this star is a former secondary component of a massive tight binary system and that its surface was polluted by the nucleosynthetic products after the primary star exploded in a supernova. It was proposed that the (asymmetric) supernova explosion unbin...

We present the X-ray observation of Vela shrapnel B with the XIS on board the Suzaku satellite. The shrapnel is one of several ejecta fragment-like features protruding beyond the primary blast wave shock front of the Vela supernova remnant. The spectrum of shrapnel B is well-represented by a singletemperature thin-thermal plasma in a non-equilibrium ionization state. The elemental abundances of...

Context. The field just West of the galactic supernova remnant W28 (l=6.4 o , b=-0.2 o) harbors 3 of 5 newly-discovered 1720 OH maser spots and two recently-discovered candidate supernova candidates (one of which is a γ-ray source), as well as several compact and classical HII regions. Aims. To show the interaction of radio supernova remnants with ambient molecular gas in sky field just West of...

conclusions according to our result, 1525g/a and 1595c/t were in strong linkage disequilibrium and the polymorphisms of the trail gene in the 3’ utr region were not associated with the outcome of hbv infection. results our data showed that genotypes 1525g/a and 1595c/t were in complete linkage disequilibrium and the genotype frequencies at the two positions were the same. no significant differe...

We have observed two fields Field I (l=3.2◦, b=−1.0◦) and Field II (l=356.8◦, b=−0.1◦) with the Giant Metrewave Radio Telescope (GMRT) at 330 MHz. In the first field, we have studied the candidate supernova remnant (SNR) G3.1−0.6 and based on its observed morphology, spectral index and polarisation confirmed it to be an SNR. We find this supernova to have a double ring appearance with a strip o...
