A novel diagnostic approach to detecting porcine epidemic diarrhea virus: The lateral immunochromatography assay.

Porcine epidemic diarrhea virus (PEDV) causes acute diarrhea and dehydration in sucking piglets and has a high mortality rate. An immunochromatography (IC) assay, known as a lateral flow test, is a simple device intended to detect the presence of target pathogens. Here, we developed an IC assay that detected PEDV antigens with 96.

The CSFV DNAChip: a novel diagnostic assay for classical swine fever virus.

A novel assay, the CSFV DNAChip, was developed to clearly and rapidly discriminate three genotypes of classical swine fever virus (CSFV). Total RNA was extracted from clinical samples and then subjected to a one-step reverse-transcription polymerase chain reaction (RT-PCR) using Cy3-labeled primers from the 5' non-coding region (NCR) of CSFV. Amplicons were hybridized to the CSFV DNAChip and fluorescence scanning was performed for detection of CSFV.

One-step multiplex reverse-transcriptase PCR for detecting pandemic (H1N1) 2009 influenza virus.

Pandemic (H1N1) 2009 influenza has spread throughout the world since April 2009 and has caused many human deaths since its first report in humans. Pandemic (H1N1) 2009 influenza virus was first identified in a Canadian pig herd in April 2009 and has been reported in more than ten countries, including Korea. We developed a one-step multiplex reverse transcriptase polymerase chain reaction (RT-PCR) assay based on the matrix gene that discriminates pandemic (H1N1) 2009 influenza virus from endemic swine influenza viruses.

Induction of apoptosis by KI0477959 through activation of caspase-3 in human leukemia cell line, HL-60 cells.

KI0477959 (Herbkines) has been used for the purpose of development of physical strength in wasting diseases, like cancer. In the present study, apoptosis-inducing activities of butanol fraction of KI0477959 were studied in human leukemia cell line, HL-60 cells. KI0477959 increased cytotoxicity but had less effect on human peripheral blood mononuclear cells.

Vascular endothelial growth factor is regulated by hypoxic stress via MAPK and HIF-1 alpha in the inner ear.

Vascular endothelial growth factor (VEGF) is a key regulator of angiogenesis. The iron-chelator desferrioxamine (DFX) increased the expression of hypoxia-inducible factor (HIF)-1alpha in the hair cell line, HEI-OC1. The increased VEGF production by DFX was inhibited by iron.

Immune-enhancement effect of the herbal combination Allergina.

Background: The herbal formulation, Allergina, has long been used for various diseases. It is known to have an anti-microbial and anti-virus activity. However, it is still unclear how Allergina has these effects in experimental models.
