Article Abstract
Objectives: To develop a real-time quantitative PCR assay to detect duck plague virus (DPV) for the rapid diagnosis of DPV infection, the investigation of its nosogenesis and the screening of effective antiviral drugs.
Methods: The primer and probe were designed according to the gene sequence of DPV DNA polymerase gene. To establish a standard curve, a plasmid containing 125 bp PCR product was constructed and severed as a positive control. The TaqMan based real-time PCR method was adopted and compared with the traditional PCR approach in sensitivity, reliability and specificity.
Results: A good linear correlation was demonstrated in the standard curve for the real-time PCR assay within the range from 2.3 x 10 to 2.3 x 10(5) copies. A minimum of 23 positive plasmids could be detected, indicating a good sensitivity of the assay. The coefficients of variance (CVs) were 1.22-6.69 and 2.09-8.84 for the intra-assay and inter-assay tests respectively, indicating a good reliability. No amplification products were found for DNA from other pathogens, indicating a good specificity. The comparative study proved that the TaqMan technology was much more sensitive than traditional PCR assay.
Conclusion: The real-time quantitative PCR assay for DPV DNA has good sensitivity, specificity and reliability.
The aim of the present study was to explore the role of ovarian cancer G protein-coupled receptor 1 (OGR1) in osteoclast differentiation and activity induced by extracellular acid. The impact of extracellular acidification on osteoclasts was investigated. Briefly, osteoclasts were generated from RAW 264.
Objective: This study aimed to investigate the underlying mechanism of chronic stress promoting ovarian cancer growth comorbid with depression and evaluate the potential role of histamine (HIS) in treating this comorbidity.
Methods: Chronic unpredictable mild stress (CUMS) was used to establish a comorbid mouse model of ovarian cancer and depression. The behavioral phenotypes were assessed using the sucrose preference test (SPT), tail suspension test (TST), forced swimming test (FST), and open field test (OFT).
Purpose: Aplastic anemia (AA) is a bone marrow failure syndrome with an unclear pathogenesis. Abnormal T cell immunity is one of the mechanisms involved in AA, and CD3ζ is an important signaling molecule for T cell activation. Single-nucleotide polymorphisms (SNPs) in CD3ζ 3'-untranslated region (3'-UTR) were associated with some immune-related disease occurrence and affect CD3ζ protein level.
Breast cancer (BC) is a malignant tumor, that damages the physical health of female patients. It is crucial to develop new treatment strategies for BC, as this disease significantly affects the quality of life of women in both developing and developed countries, despite the existence of effective treatment options to reduce mortality. Recently, several researchers have been studying circular RNAs (circRNAs) in BC due to their stability and sponge function.

Animal tuberculosis (TB) has been reported in several wildlife species in the Greater Kruger Conservation Area (GKCA), South Africa. This report describes the discovery of clinical tuberculosis, caused by (), in free-ranging vervet monkeys (). The "One Health" concept is especially relevant to TB since this is a multi-host disease with zoonotic potential and is endemic in GKCA.
