[Examining the Role of Nanomaterials and Optical Sensors for Genomics Research]

This presentation introduces the possibility of using nanomaterials and optically active sensors in genomics research. The presenter shares the history and applications of nanomaterials, introduces their research into optical-luminescent sensors and optically active plasmonic nanoparticles, and explores how they might be used in genomics. It was presented at the UNT Transdisciplinary Conference on Ancestral Genomics Research which was held virtually on November 20-21, 2020.

In vitro anti-diabetic effects and phytochemical profiling of novel varieties of Cinnamomum zeylanicum (L.) extracts (open access)

In vitro anti-diabetic effects and phytochemical profiling of novel varieties of Cinnamomum zeylanicum (L.) extracts

Article exploring the use of pressured and decoctions water to extract anti-diabetic phytochemicals from cinnamon. The extensive metabolite profiling of novel SW and SG extracts and comparison of that with commercially available CC are reported for the first time in this study. The C. zeylanicum, SW accession holds some promise in the management of diabetes.

Charge stabilization via electron exchange: excited charge separation in symmetric, central triphenylamine derived, dimethylaminophenyl–tetracyanobutadiene donor–acceptor conjugates (open access)

Charge stabilization via electron exchange: excited charge separation in symmetric, central triphenylamine derived, dimethylaminophenyl–tetracyanobutadiene donor–acceptor conjugates

This article hypothesizes and demonstrates a new mechanism to stabilize the charge separated states via the process of electron exchange among the different acceptor entities in multimodular donor–acceptor conjugates. This work constitutes the first example of stabilizing charge-separated states via the process of electron exchange.

Chemical and Genetic Studies on the Formation of Pyrrolones During the Biosynthesis of Cytochalasans (open access)

Chemical and Genetic Studies on the Formation of Pyrrolones During the Biosynthesis of Cytochalasans

This article investigates the role of the highly conserved α,β-hydrolase enzymes PyiE and ORFZ during the biosynthesis of pyrichalasin H and the ACE1 metabolite, respectively, using gene knockout and complementation techniques. Taken together the results suggest that the α,β-hydrolase enzymes are essential for first ring cyclisation, but the precise nature of the intermediates remains to be determined.
