Quantitative Proteomics for Cardiac Biomarker Discovery Using Isoproterenol-Treated Nonhuman Primates
To identify new cardiac biomarkers, a quantitative proteomic analysis has been performed on serum and heart tissue proteins from three species of nonhuman primates following isoproterenol (ISO) treatment.

Comparative Analysis of Knowledge Representation and Reasoning Requirements across a Range of Life Sciences Textbooks
(Previously) we showed that embedding the knowledge representation and question-answering abilities in an electronic textbook helped to engage student interest and improve learning. A natural question that arises from this success, and this paper’s primary focus, is whether a similar approach is applicable across a range of life science textbooks.

Conservative Groupoids Recognize Only Regular Languages
The notion of recognition of a language by a finite semigroup can be generalized to recognition by finite groupoids, i.e. sets equipped with a binary operation ‘⋅’ which is not necessarily associative.

Effects of Nmda Receptor Antagonism on High Frequency Neuronal Oscillations and Working Memory Performance in Cynomolgus Macaques
Our results suggest that acute administration of a NMDA receptor antagonist disrupts neuronal oscillations and cognitive processing and this may contribute to impaired cognitive performance in macaques.
