We determined the prevalence of hepatitis C virus (HCV) in hemodialysis patients by antibody testing and HCV RNA determination by PCR. A total of 149 patients with kidney failure with replacement therapy were tested. The prevalence of anti-HCV was 6.7% (10 of 149 patients), and viremia was detectable in 8 of 149 (5%) patients. Three of 149 patients (2%) were anti-HCV negative with detectable HC...

Background: Smoking can cause increase of DNA methylation and hypermethylation of tumor suppressor genes, this possible contributing to subsequent lung cancer development. DNA methyltransferase 3B (DNMT3B) is crucial in regulation of DNA methylation and it has been proposed that green tea might lower cancer risk through inhibiting its activity. Here, we designed a case-control study to investig...

This paper examines the problem of a moving robot tracking a moving object with its cameras, without requiring the ability to recognize the target to distinguish it from distracting surroundings. A novel aspect of the approach taken is the use of controlled camera movements to simplify the visual processing necessary to keep the cameras locked on the target. A gaze holding system implemented on...

A single-round polymerase chain reaction (PCR) diagnostic assay was developed from a small subunit ribosomal DNA (SSU rDNA) gene sequence to detect the myxozoan parasite Kudoa neurophila, the causative agent of myxozoan disease in the hatchery reared marine finfish, striped trumpeter Latris lineata (Forster). The assay was developed for use as a disease control management tool in a hatchery sys...

1. The structure of one class of giant tangential neurons in the lobula plate of Calliphora, the `Vertical System (VS)' has been investigated by light microscopy. Different staining and reconstruction procedures were employed to ensure that all existing VS-neurons are revealed. 2. There are 11 VS-cells in a characteristic, and constant arrangement (Fig. 2). Each cell covers a particular area of...

MicroRNAs (miRs) play critical roles in the progression of glioma. Previous in vitro studies have described the anti-tumor role of miR-149 in cancer cells including glioma. In this study, we aimed to investigate whether miR-149 is associated with the prognosis of glioma patients. A total of 163 glioma patients who underwent tumor resection were included in our follow-up study. We found that the...

Non-alcoholic fatty liver disease (NAFLD), a lipid metabolism disorder characterized by the accumulation of intrahepatic fat, has emerged as a global public health problem. However, its underlying molecular mechanism remains unclear. We previously have found that miR-149 was elevated in NAFLD induced by high-fat diet mice model, whereas decreased by a 16-week running programme. Here, we reporte...

microRNAs play key roles during various crucial cell processes such as proliferation, migration, invasion and apoptosis. Also, microRNAs have been shown to possess oncogenic and tumor-suppressive functions in human cancers. Here, we describe the regulation and function of miR-149 in colorectal cancer cell lines. miR-149 expression patterns were detected in human colorectal cell lines and tissue...

CheA is a histidine kinase central to the signal transduction pathway for chemotaxis in Escherichia coli. CheA autophosphorylates at His-48, with ATP as the phosphodonor, and then donates its phosphoryl groups to two aspartate autokinases, CheY and CheB. Phospho-CheY controls the flagellar motors, whereas phospho-CheB participates in sensory adaptation. Polypeptides encompassing the N-terminal ...
