Computation of Atmospheric Concentrations of Molecular Clusters from ab initio Thermochemistry Tuguldur T. Odbadrakh1, Ariel G. Gale1, Benjamin T. Ball1, Berhane Temelso2, George C. Shields1 1Department of Chemistry, Furman University, 2College of Charleston The atmospheric concentrations of weakly bound molecular clusters can be computed from the thermochemical properties of low energy structures found through a multi-step configurational sampling methodology utilizing a genetic algorithm and semi-empirical and ab initio quantum chemistry.
Detecting Estrogenic Ligands in Personal Care Products using a Yeast Estrogen Screen Optimized for the Undergraduate Teaching Laboratory Thea M. Edwards1,2, Howard E. Morgan2,3, Coralia Balasca4, Naveen K. Chalasani5, Lauren Yam4,6, Alison M. Roark4 1Department of Biology, University of the South, 2School of Biological Sciences, Louisiana Tech University, 3School of Medicine, Louisiana State University Health Sciences Center, 4Department of Biology, Furman University, 5Department of Computer Science, Louisiana Tech University, 6Clemson University This article presents an optimized yeast estrogen screen for quantifying ligands in Personal Care Products (PCPs) that bind estrogen receptors alpha (ERα) and/or beta (ERβ). The method incorporates two colorimetric substrate options, a six-day refrigerated incubation for use in undergraduate courses, and statistical tools for data analysis.
The Use of Flow Cytometry to Assess the State of Chromatin in T Cells Kellie N. Bingham*1, Megan D. Lee*1, Jason S. Rawlings1 1Department of Biology, Furman University Flow cytometry can be utilized to assess the state of chromatin within T cells. This protocol allows scientists to interpret evidence of chromatin decondensation during T cell activation demonstrated by an increase in the mean florescence intensity (MFI) of fluorescent Histone H3 antibodies
