An optimized visual loop mediated isothermal amplification assay for efficient detection of minute virus of mice with hydroxynaphthol blue dye.

Minute virus of mice (MVM) is one of the most prevalent infectious agents in laboratory mouse colonies. In this study, we optimized a loop-mediated isothermal amplification (LAMP) assay using hydroxynaphthol blue (HNB) for rapid and visual detection of MVM. The reaction, which entailed addition of HNB dye prior to amplification, was performed in one step in a single tube at 62 °C for 45 min.

PK15 cell line stably overexpressing IL2 enhances PCV2 replication.

Porcine circovirus type 2 (PCV2) is the primary agent responsible for porcine circovirus-associated diseases (PCVADs), which is acknowledged as one of the most economically important diseases for the swine industry worldwide. Currently, the development of PCV2 vaccine against PCVADs and for other applications require large amounts of viral particles. The low propagation rate of PCV2 in vitro limits vaccine production.

Effect of heat shock on murine norovirus replication in RAW264.7 cells.

Murine norovirus (MNV), is a prevalent pathogen of laboratory mice closely related to human norovirus (HuNoV), a contagious pathogen known to cause gastroenteritis worldwide; however, the mechanism of norovirus replication remains poorly understood. Both heat shock protein 90 (Hsp90) and heat shock protein 70 (Hsp70) play an important role in viral genome replication and viral gene expression. In this study, we first found that heat stress exerted a positive effect on the replication of MNV in the murine macrophage RAW264.

The local heating effect by magnetic nanoparticles aggregate on support lipid bilayers.

In this paper, we established a theoretical model to investigate the local heating effect of magnetic nanoparticles (MNPs) aggregate on the support lipid bilayers (SLBs) under external alternating current (AC) magnetic field, which may be helpful to understand hyperthermia at single cell level. Using atomic force microscope (AFM), the transformation of the support phospholipid bilayers surrounding MNPs aggregate was observed in real-time. We found that the fluidity of lipid bilayers changed when the size of MNPs aggregate larger than 200 nm, as a result of magnetic heating in the AC magnetic field.

Immunostaining with EGFR mutation-specific antibodies: a reliable screening method for lung adenocarcinomas harboring EGFR mutation in biopsy and resection samples.

Mutation analysis of epidermal growth factor receptor (EGFR) is essential in determining the therapeutic strategy for lung adenocarcinoma. Immunohistochemical (IHC) staining with EGFR mutation-specific antibodies of del E746-A750 in exon 19 and L858R in exon 21 has been evaluated in resection specimens in a few studies but rarely in biopsy samples. A total of 169 cases (78 biopsies and 91 resected specimens) of lung adenocarcinoma with EGFR mutation status predefined by direct DNA sequencing were histologically examined, and IHC was performed using EGFR mutation-specific antibodies of del E746-A750 and L858R.

Amplification of the telomerase RNA component gene as a new genetic marker for disease progression and prognosis in esophageal squamous cell carcinoma.

Amplification of the human telomerase RNA component (TERC) gene was found in esophageal squamous cell carcinoma (ESCC). However, its roles in the progression and prognosis of ESCC have not been well understood. The amplification of TERC in normal mucosa, low-grade and high-grade intraepithelial neoplasia, and invasive ESCC samples were evaluated using a fluorescence in situ hybridization assay.

Endolymphatic sac tumor with von Hippel-Lindau disease: report of a case with analysis of von Hippel-Lindau gene and review.

Endolymphatic sac tumors (ELSTs) are very rare and locally aggressive low-grade neoplasm of endolymphatic system origin, which are associated with von Hippel-Lindau (VHL) disease. Evidence suggests that the specific VHL alteration influences the phenotype. Because of the rarity of ELSTs, only a small number of cases have been subjected to molecular genetic analysis.
