Thyroid hormone responsive spot 14 (THRSP, Spot14, S14) is a nuclear protein that regulates milk fat synthesis. To investigate the role of THRSP in lipogenesis in the dairy cow mammary gland, first, we examined the association between milk fat concentration and THRSP expression in the mammary gland. We found that the dairy cow mammary glands that produced(More)
Rational, de novo design of RNA nanostructures can potentially integrate a wide array of structural and functional diversities. Such nanostructures have great promises in biomedical applications. Despite impressive progress in this field, all RNA building blocks (or tiles) reported so far are not geometrically well defined. They are generally flexible and(More)
Low-energy ion implantation was employed to breed laccase producing strain Paecilomyces sp. WSH-L07 and a mutant S152 that exhibited an activity of more than three times over the wild strain was obtained. The optimum substrate of both the wild and mutant laccases was 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonate), and followed by guaiacol with optimal(More)
Laccase can catalyze the oxidation of a wide range of organic and inorganic substrates. In this study, an easily detectable method was employed for screening laccase-producing microorganisms by using 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonate) (ABTS) as laccase-secretion indicator. A novel laccase-producing strain was isolated and identified as(More)
Here we report the assembly of multilayered DNA nanocages. The layers can be separated in response to a chemical cue, ATP. This is an effort to increase the structural complexity of DNA nanocages. The structures have been characterized by native polyacrylamide gel electrophoresis, atomic force microscopy, and cryogenic electron microscopy. We envision that(More)
Many polysaccharides have biological activities and have been investigated for their antitumor effects. In this study, we investigated the anti-tumor activity and anti-virus activity of SNP-the water-soluble polysaccharides extracted from Sipunculus nudus on Hepg2.2.15. Flow cytometry analysis demonstrated that SNP induced dose-dependent cell apoptosis on(More)
BACKGROUND The spoilage bacterial community in oyster gill was investigated during storage at 4, 10 and 20 °C. Aerobic plate counts and pH values were determined. Total bacterial DNA was extracted from oyster gill and bulk cells of plate count media. The major bacterial species during fresh or different temperatures storage were determined by polymerase(More)
TOPKAPI is a physically-based, fully distributed hydrological model with a simple and parsimonious parameterisation. The original TOPKAPI is structured around five modules that represent evapotranspiration, snowmelt, soil water, surface water and channel water, respectively. Percolation to deep soil layers was ignored in the old version of the TOPKAPI model(More)
