In the present study, Listeria monocytogenes BCRC 14846 and Salmonella Typhimurium BCRC 10747 were subjected to acid adaptation at pH 5.5 at 37°C for 1 and 4 h, respectively. The viability of the acid-adapted cells of test organisms exposed to Clidox-S, a chlorine-containing disinfectant, and Quatricide, a quaternary ammonium compound, was examined and(More)
BACKGROUND AND PURPOSE Appetite suppression induced by amphetamine has been attributed to its inhibition of neuropeptide Y (NPY) neurons and activation of pro-opiomelanocortin (POMC) neurons in the hypothalamus. This study examined whether STAT3 was involved in these actions of amphetamine. EXPERIMENTAL APPROACH Rats were given amphetamine daily for 4(More)
A novel remotely triggered drug vehicle having multimodal imaging functionality was developed. It exhibits magnetic resonance (MR) imaging, ultrasound (US) imaging, encapsulation of a hydrophobic agent and US-triggered release behavior. Lipophilic superparamagnetic iron oxide (SPIO) nanoparticles were self-assembled with an amphiphilic chitosan derivative,(More)
The conventional auto-focus and zoom image systems were made by a set of motor-moved lenses. Because of mechanical moving parts, it is not easy to miniaturize their sizes. In this paper, we propose a thin autofocus system using a large stroke MEMS (micro-electro-mechanical systems) deformable mirror which has the potential to downscale the size and to(More)
The newly emerging Middle East respiratory syndrome coronavirus (MERS-CoV) encodes the conserved macro domain within non-structural protein 3. However, the precise biochemical function and structure of the macro domain is unclear. Using differential scanning fluorimetry and isothermal titration calorimetry, we characterized the MERS-CoV macro domain as a(More)
The foodborne pathogens Listeria monocytogenes and Salmonella Typhimurium were subjected to heat shock at 48°C for 10 and 30 min, respectively, and then cold shocked at 15°C for 3 h. The effect of these shocks on the viability of test organisms exposed to chlorine dioxide and quaternary ammonium compounds was then determined. After exposure to the(More)
The lack of a human papillomavirus (HPV)-infected skin cancer cell line has hampered the investigation of the interaction of UV and HPV in skin carcinogenesis. We identified a human basal cell carcinoma (BCC-1/KMC) cell line integrated with E6 and E7 genes of high-risk HPV type 18 and demonstrated that repression of E6 and E7 results in proliferation(More)
