Mortality from myeloid leukosis was observed in commercial layers from 12 farms in northern China. Affected chickens were extremely thin and dehydrated, bleeding occurred in feather follicles and claws, combs were pale and anaemic, phalanges were swollen, and many yellowish-white tumours were seen on the visceral surface of the sternum. Focal tumour cells,(More)
Coordinated scan can gather host information for further attack more efficiently and stealthily than single-source port scans by distributing tasks amongst multiple sources. The existing coordinated scan detection methods are mostly based on scan behavior characteristics in temporal or spatial correlation. However, these detection methods can be easily(More)
Anemia is a common nutritional problem, and it has a remarkably high prevalence rate in Southeast Asia. In this study, children from 6 to 36 months were investigated to determine (1) the prevalence of anemia and (2) risk factors associated with anemia. Convenience sampling was used to select three villages in three different regions in Burma. Hemoglobin and(More)
To explore the effects of the genetic background on the characteristics of wboA gene deletion rough mutants generated from different parent Brucella sp. strains, we constructed the rough-mutant strains Brucella melitensis 16 M-MB6, B. abortus 2308-SB6, B. abortus S19-RB6, and B. melitensis NI-NB6 and evaluated their survival, pathogenicity, and induced(More)
The emergence of methicillin-resistant Staphylococcus aureus (MRSA) infection in dairy animals is of great concern for livestock and public health. The aim of present study was to detect new trends of methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-sensitive Staphylococcus aureus (MSSA) towards antibiotic susceptibility, resistance genes(More)
Previous studies have demonstrated the key regulatory roles played by microRNAs (miRNAs) in influenza virus-host interactions. To gain more insight into the contribution of miRNAs to the host immune response, spleen tissues from mice infected with A/Swine/GD/2/12 (H1N1) virus were harvested 5 days postinfection, and miRNA deep sequencing was performed. The(More)
The denitrification for the coking wastewater was conducted by means of original battery principle with Fe-C micro-electrolysis. Fe-C serves as positive and negative electrodes, by which N02(-)-N and TN were reduced to nitrogen, and then the purpose of denitrifieation for coking wastewater was realized. The influences of pH value, carbon particle size, Fe/C(More)
OBJECTIVE To identify the effects of infant formula on the reproductive development of Spraque-Dawley rats. METHODS A two-generation reproductive test was carried out. Forty 4 week-old SD rats were divided into two groups randomly by body weight and maintained on diet containing a kind of infant formula or an adjusted basal feeds. The body weight, dietary(More)
