Short-chain fatty acids (SCFAs) are physiological regulators of growth and differentiation in the gastrointestinal tract, and we have previously shown that apoptosis induced in colonic cell lines by these compounds is dependent on their metabolism by B-oxidation in the mitochondria (B. G. Heerdt et al., J. Biol. Chem., 266: 19120-19126, 1991; Cancer Res.,(More)
This report describes and discusses the history, clinical, pathologic, epidemiologic, and human health aspects of an outbreak of Mycobacterium bovis infection in domestic wapiti in Alberta between 1990 and 1993, shortly after legislative changes allowing game farming. The extent and seriousness of the outbreak of M. bovis in wapiti in Alberta was not fully(More)
Data on the bioavailability and toxicity of carbon nanotubes (CNTs) in the environment, and, in particular, on their interactions with vascular plants, are limited. We investigated the effects of industrial-grade multiwalled CNTs (75 wt% CNTs) and their impurities on alfalfa and wheat. Phytotoxicity assays were performed during both seed germination and(More)
Raman spectroscopy is among the primary techniques for the characterisation of graphene materials, as it provides insights into the quality of measured graphenes including their structure and conductivity as well as the presence of dopants. However, our ability to draw conclusions based on such spectra is limited by a lack of understanding regarding the(More)
