In eukaryotes, aberrant expression of transposable elements (TEs) is detrimental to the host genome. Piwi-interacting RNAs (piRNAs) of ∼23 to 30 nucleotides bound to PIWI clade Argonaute proteins silence transposons in a manner that is strictly dependent on their sequence complementarity. Hence, a key goal in understanding piRNA pathways is to determine mechanisms that modulate piRNA sequences....

Cytochrome P450 enzymes from the CYP2C subfamily play a prominent role in the metabolic clearance of many drugs. CYP2C enzymes have also been implicated in the metabolism of arachidonic acid to vasoactive epoxyeicosatrienoic acids. CYP2C8, CYP2C9, and CYP2C19 are expressed in the adult liver at significant levels; however, the expression of CYP2C enzymes in extrahepatic tissues such as the brai...

Throughout the world, there are many threats to existing coral reefs. Global warming (1), mining (2), overfishing (3), and water pollution (4) all threaten the viability and health of coral reefs. Although these threats are well documented, programs to protect coral reefs are spotty and underfunded. Advocates for coral reef protection argue that there are many benefits to maintaining coral reef...

One important generalization to emerge from Table 1 is that the accuracy rate improves for each corpus using the tagger trained on both corpora instead of the taggers trained on a single corpus. This exemplifies that common result that accuracy improves by simply including more training data, even if it from a different genre. However, it is interesting to note that the accuracy improved more f...

Stereoselectively labelled isotopomers of NAD(P)H are highly relevant for mechanistic studies of enzymes which utilize them as redox equivalents. Whereas several methods are firmly established for their generation in high diastereomeric purity by enzymatic methods, alternative methods have so far not been investigated. The article presents the stereoselective deuteration of NAD at the 4-positio...
