The murine MTH1 gene codes for MTH1, an 8-oxo-2'-deoxyguanosine 5'-triphosphate pyrophosphohydrolase (8-oxo-dGTPase) which hydrolyzes 8-oxo-dGTP, a promutagenic product of reactive oxygen species' attack on the nucleotide pool. This gene is regulated by oxidative stress. Therefore, we hypothesized that MTH1 expression can be affected by carcinogenic nickel(II), known to induce such stress. Thre...

BACKGROUND Aggregatibacter actinomycetemcomitans is the etiological agent of periodontitis, and there is a strong association between clone JP2 and aggressive periodontitis in adolescents of African descent. The JP2 clone has an approximately 530-bp deletion (∆530) in the promoter region of the lkt/ltx gene, which encodes leukotoxin, and this clone has high leukotoxic activity. Therefore, this ...

The goal of this project is to attribute the authorship of excerpts from a set of New York Times articles to author Gina Kolata. The training data included labeled excerpts from New York Times as Gina Kolata vs other authors. We extracted and tried a multitude of features, setting the baseline as an SVM on 1000 most frequent words and then moving onto more complex features like Parts-of-Speech,...
