The IL-2/IL-2R signaling pathway has an important role in autoimmunity. Several genes identified in genome-wide association (GWA) studies encode proteins in the IL-2/IL-2R signaling cascade that are associated with autoimmune diseases. One of these, PTPN2, encodes a protein tyrosine phosphatase that is highly expressed in T cells and regulates cytokine(More)
To trace evolution of canine parvovirus-2 (CPV-2), a total of 201 stool samples were collected from dogs with diarrhea in Heilongjiang province of northeast China from May 2014 to April 2015. The presence of CPV-2 in the samples was determined by PCR amplification of the VP2 gene (568 bp) of CPV-2. The results revealed that 95 samples (47.26%) were positive(More)
Canine kobuviruses (CaKVs) are newly recognized picornaviruses that have been recently detected in dogs in the U.S.A., Italy, U.K., the Republic of Korea and Tanzania. To trace the evolution of CaKV strains, a total of 201 fecal samples from rectal swabs of diarrheic dogs, which were obtained from May 2014 to April 2015 in northeast China, were detected by(More)
MinION is a memory stick-sized nanopore-based sequencer designed primarily for single-molecule sequencing of long DNA fragments (>6 kb). We developed a library preparation and data-analysis method to enable rapid real-time sequencing of short DNA fragments (<1 kb) that resulted in the sequencing of 500 reads in 3 min and 40,000-80,000 reads in 2-4 hr at a(More)
IL-2 receptor (IL-2R) signaling is essential for optimal stability and function of CD4(+)CD25(hi)FOXP3(+) regulatory T cells (Treg); a cell type that plays an integral role in maintaining tolerance. Thus, we hypothesized that decreased response to IL-2 may be a common phenotype of subjects who have autoimmune diseases associated with variants in the IL2RA(More)
To trace the evolution of canine coronavirus (CCoV), 201 stool samples from diarrheic dogs in northeast China were subjected to reverse transcription-polymerase chain reactions (RT-PCRs) targeting the partial M and S genes of CCoV, followed by an epidemiological analysis. M gene RT-PCRs showed that 28.36% (57/201) of the samples were positive for CCoV; of(More)
In an effort to trace the evolution of porcine epidemic diarrhea virus (PEDV), S1 and ORF3 genes of viruses identified in 41 pig farms from seven regions (North, Northeast, Northwest, Central, East, South West, and South, respectively) of China in 2015 were sequenced and analyzed. Sequence analysis revealed that the 41 ORF3 genes and 29 S1 genes identified(More)
This paper focuses on the study of social media's knowledge management in natural disaster response by the analysis of the literature in the field of disaster management. There are two cases in this paper: Wenchuan's earthquake in 2008 and Haiti's earthquake in 2010. Firstly, social media's advantages of knowledge management in natural disaster response(More)
In the plasma of dairy cows with 1–5 points of lameness, the mineral elements [calcium (Ca), iron (Fe), copper (Cu), zinc (Zn), iodine (I), selenium (Se), molybdenum (Mo), and chromium (Cr)], the energy metabolic indicators [triglyceride (TG), glucose (Glu), total cholesterol (CHO), nonesterified fatty acids (NEFA), β-hydroxybutyrate (BHBA), lactate (LA),(More)
