Human enteric viruses are currently recognized as one of the most important causes of food-borne disease. Implication of enteric viruses in food-borne outbreaks can be difficult to confirm due to the inadequacy of the detection methods available. In this study, a nucleic acid sequence-based amplification (NASBA) method was developed in a multiplex format for the specific, simultaneous, and rapi...

The aim of this study was to produce a sensitive, simple and rapid diagnostic method for the detection of foot-and-mouth disease virus (FMDV) in suspected cases of FMD, a one-step single-tube method of reverse transcription loop-mediated isothermal polymerase amplification (RT-LAMP). A set of six common primers was designed to target the highly conserved region of the RNA polymerase 3Dpol gene ...

We report the first seroprevalence study of the occurrence of specific antibodies to European bat lyssavirus type 2 (EBLV-2) in Daubenton's bats. Bats were captured from 19 sites across eastern and southern Scotland. Samples from 198 Daubenton's bats, 20 Natterer's bats, and 6 Pipistrelle's bats were tested for EBLV-2. Blood samples (N = 94) were subjected to a modified fluorescent antibody vir...

BACKGROUND Real-time quantitative reverse transcription PCR (RQ-PCR) assay for BCR-ABL is used to monitor treatment response in chronic myeloid leukemia (CML). BCR-ABL transcript levels decline over several years of imatinib treatment, and increasing numbers of patients have BCR-ABL transcripts at or below the limit of detection. More sensitive PCR methods are required to assess whether these p...

background: this study detected osteopontin (opn) and matrix metalloproteinase-7 (mmp-7) expressions to explore the roles of opn and mmp-7 in the occurrence, progression, and prognosis of nonsmall cell lung cancer (nsclc). materials and methods: a retrospective study was conducted on nsclc tissues ( n = 152; case group) and adjacent nonneoplastic lung parenchyma (adjacent to tumor >5 cm; n = 15...

Seven children were followed for up to 42 days post-vaccination with live mumps vaccine and 37 throat swabs were obtained serially. Viral genomic RNA was detected by reverse transcription-polymerase chain reaction (RT-PCR) in the phosphoprotein (P) and hemagglutinin-neuraminidase (HN) regions. Virus isolation was also attempted. Genomic differentiation of detected mumps virus genome was perform...

BACKGROUND Recent studies in both humans and animal models strongly suggest the contribution of the host immune response to Helicobacter pylori-related disease. Inducible nitric oxide synthase has been shown to be up-regulated in the gastric epithelium during H. pylori gastritis, suggesting a role in inflammation. MATERIALS AND METHODS C57BL/6 wild-type and inducible nitric oxide synthase gen...

abstract the variables affecting the nature of reading comprehension can be classified into two general categories: reader’s variables, and text variables (alderson, 2000). despite the wave of research on vocabulary knowledge as reader’s variable, the role of this knowledge in c-test as a text-dependent test and its interaction with lexical cohesion of the test as a text feature has remained a...

L1 retrotransposons have a prominent role in reshaping mammalian genomes. To replicate, the L1 ribonucleoprotein particle (RNP) first uses its endonuclease (EN) to nick the genomic DNA. The newly generated DNA end is subsequently used as a primer to initiate reverse transcription within the L1 RNA poly(A) tail, a process known as target-primed reverse transcription (TPRT). Prior studies demonst...

Buckwheat rutin has been found to be able to inhibit angiotensin II (AngII) - induced hypertrophy in cultured neonatal rat cardiomyocytes, but the mechanism remains uncertain. In this study, myocardial hypertrophy model was made by adding AngII to the medium of cardiac myocytes of neonatal rats, meanwhile, different concentrations of buckwheat rutin were applied to observe their effects. Intrac...
