Reactive immunization with a single-dose cholera vaccine that could rapidly (within days) protect immunologically-naïve individuals during "virgin soil" epidemics would facilitate cholera control. One dose of attenuated Vibrio cholerae O1 classical Inaba vaccine CVD 103-HgR (Vaxchora™) containing ≥2x108 colony forming units (cfu) induces vibriocidal antibody seroconversion (correlate of protect...
The cytopathology for rat neuroblastoma cells (B-103) and the pathogenicity for B6C3F1 mice of four species of Naegleria have been compared. Both live amoebae and cell-free extracts of N. australiensis, N. fowleri, N. gruberi, and N. lovaniensis added to 51Cr-labeled B-103 cells caused release of radiolabel. All four species of Naegleria exhibited surface extensions termed food cups. Only N. fo...
TAS-103, a new anticancer drug, induces DNA cleavage by inhibiting the activities of topoisomerases I and II. We investigated the mechanism of TAS-103-induced apoptosis in human cell lines. Pulsed field gel electrophoresis revealed that in the leukemia cell line HL-60 and the H(2)O(2)-resistant subclone, HP100, TAS-103 induced DNA cleavage to form 1-2-Mb fragments at 1 h to a similar extent, in...
Bacteriophage are viruses that can infect and kill bacteria. A study was conducted to determine if bacteriophage added to drinking water for 1 wk prior to respiratory challenge of broiler chickens with E. coli would provide protection. There were 12 treatments with 2 replicate pens of 10 chicks. The treatments consisted of birds on normal water challenged at 1 wk with either 103 or 104 cfu E. c...
MicroRNAs (miRNAs) are a class of small, noncoding RNAs that act as key regulators in various physiological and pathological processes. However, the regulatory mechanisms for miRNAs in colorectal cancer remain largely unknown. Here, we found that miR-103 is up-regulated in colorectal cancer and its overexpression is closely associated with tumor proliferation and migration. In addition, repress...
Marek's disease (MD) is a highly contagious viral neoplastic disease caused by Marek's disease virus (MDV), which can lead to huge economic losses in the poultry industry. Recently, microRNAs (miRNAs) have been found in various cancers and tumors. In recent years, 994 mature miRNAs have been identified through deep sequencing in chickens, but only a few miRNAs have been investigated further in ...
The purpose of the study is to investigate Reynolds number dependency a circular arc airfoil at numbers from 1×103 10×103 by CFD. A block-structured Cartesian-mesh CFD was employed precisely predict vortex flowfields in low region. calculated aerodynamic coefficients were reasonably matched with wind tunnel tests different numbers. flow goes along upper surface lower angles attack, but separati...
Several polysiloxanes (polydimethyl, polymethyloctadecyl or polymethyltetradecyl-siloxane) were studied by FTIR spectroscopy, densimetry and gel permeation chromatography. Different types of ageings such as thermal ageing (60°C and 100°C), photo-ageing (SEPAP) and acid vapour ageing were performed and compared. Oxidation, chain scission and cross-linking were estimated after ageings. The presen...

Emerging evidence has demonstrated that microRNAs (miRNA) play a critical role in chemotherapy-induced epithelial-mesenchymal transition (EMT) in lung cancer. However, the underlying mechanism of chemotherapy-mediated EMT has not been fully elucidated. In the present study, we explored the role of miR-103 in regulating cisplatin (DDP)-mediated EMT in human lung adenocarcinoma A549/DDP cells. Re...
