Modified DNA bases are widespread in biology. 5-Methylcytosine (mC) is a predominant epigenetic marker in higher eukaryotes involved in gene regulation, development, aging, cancer, and disease. Recently, 5-hydroxymethylcytosine (hmC) was identified in mammalian brain tissue and stem cells. However, most of the currently available assays cannot distinguish(More)
High latitude waters in the Southern Ocean can be near their freezing point and remain ice-covered throughout the year whereas lower latitude Southern Ocean waters have seasonal ice coverage and comparatively large (6 °C) annual temperature changes. The genus Trematomus (suborder Notothenioidei) is regarded primarily as a high latitude group because of its(More)
The growth, survival, and life cycle progression of the freshwater ciliated protozoan Tetrahymena thermophila are responsive to protein signals thought to be released by constitutive secretion. In addition to providing insights about ciliate communication, studies of constitutive secretion are of interest for evaluating the utility of T. thermophila as a(More)
A proteomic analysis was performed on spent fermentation medium following bioreactor propagation of a wild-type industrial strain to identify proteins naturally secreted by Kluyveromyces lactis cells. Here, we report changes detected in the K. lactis secretome as a result of growth in three different carbon sources: glucose, galactose and glycerol. A total(More)
Subtle alterations in neurological function are often difficult to identify and even harder to quantitate. The identification of a neurotoxic state existing before overt behavioral changes occur has eluded quantification. It was hypothesized that a challenging signal-detection procedure would be used to assess neurological function of dialysis patients and(More)
