Recent reform initiatives in undergraduate biology call for curricula that prepare students for dealing with real-world issues and making important links between science and society. In response to this call, we have developed an issues-based laboratory module that uses guided inquiry to integrate the concepts of animal behavior and population...
Hydrogen peroxide quantification is of broad interest due to the common use of hydrogen peroxide as an oxidizing agent in industrial processing and laboratory research. Hydrogen peroxide assays are also of general importance for biological studies aimed at understanding the role of in situ generated reactive oxygen species. In the...
In biological systems, antioxidants are bioactive compounds that protect against oxidation of lipids, proteins, and DNA. Natural antioxidant peptides are often purified and isolated from proteins as a less toxic alternative to synthetic peptides, but the mechanisms behind their activity are not well understood. The purpose of this study is...
Ample research has demonstrated the largely untapped potential of bioactive peptides (BAPs) for treating systematic chronic inflammation (SCI). Protein hydrolysates are the mixture of peptides resulting from the hydrolytic breakdown of a protein. Numerous hydrolysates contain BAPs and exert beneficial effects in both in vitro and in vivo models. In...
Accelerated weathering (AW) tests have become a requirement for many wood composite products. This project monitored temperature and moisture content of specimens undergoing AW exposure for the following standards: ASTM D3434 (automatic boil test), CSA O112.9 (boil-dry-freeze), and PS2 (Section 7.17, 6-cycle VPS). Each AW procedure was conducted with three...
The concentration of ascorbic acid in the plasma was determined on
four levels of ascorbic acid intake for seven day periods in 1946-47 and
on three levels of ascorbic acid intake for ten day periods in 1947-48.
The subjects, eight girls and eight boys, were 16 to 19 year old...
Quantitative literacy is essential to biological literacy (and is one of the core concepts in Vision and Change in Undergraduate Biology Education: A Call to Action; AAAS 2009). Building quantitative literacy is a challenging endeavor for biology instructors. Integrating mathematical skills into biological investigations can help build quantitative literacy. In...
Species identification is essential to biology, conservation, and management. The ability to focus on specific diagnostic characteristics of a species helps improve the speed and accuracy of identification. Birds are excellent subjects for teaching species identification because, in combination with their different shapes and sizes, their plumages have distinctive colors...
This dissertation focused on data mining in food science research and on the technical functional properties of wheat straw-derived biorefinery-byproduct fiber preparations as related to potential applications as food ingredients. This first study evaluated the importance of electronic bibliographic database selection and multiple database usage during the information retrieval phase...
The Next Generation Science Standards (NGSS Lead States, 2013) recommend that science courses engage communities of students in scientific practices that include building accurate conceptual models of phenomena central to the understanding of scientific disciplines. We offer a set of activities, implemented successfully at both the secondary and postsecondary levels,...
