Analyzing the 2011 NAEP Results: Where Does Arkansas Stand Now?

State education policymakers in Arkansas, and in all states around the country, take great interest in the state assessment scores published each year and are pleased when they are able to present positive results. This has certainly been the case in Arkansas with the annual publication of the results of student performance on the state Benchmark exams. While the state exams provide useful information that allow policymakers to compare schools and districts within Arkansas, they do not allow policymakers to assess the performance of Arkansas students relative to other students in the nation

Solid-state switching used to speed up capacitive integrator

Capacitive integrator circuit using Silicon Controlled Switches /SCS/ insures output voltage linearly proportional to input pulse width. This circuit provides high input impedance and relatively low output impedance

Improving binding affinity through cyclization

Cancer chemotherapy results in systematic damage as the drugs used are also toxic to benign tissue. Sensitizing a cancer cell to therapy by interfering with the DNA repair mechanisms would decrease overall toxicity, as the necessary dosage of chemotherapy drugs would be lowered. The Hartman lab developed a peptide (8.6) that binds with a KD of 1 μM to the C-terminal domain of breast cancer associated protein (BRCA1), blocking homologous recombination. The crystal structure of the peptide shows the tyrosine and threonine residues are close together, suggesting that by cyclizing these positions, the peptide may already be constrained into its bound conformation. A series of dibromomethylnaphthalene linkers of various length were synthesized and cyclized through alkylation of the cysteine residues on peptide 8.6. The binding of the cyclic peptides with the BRCA1 (BRCT)2 domain will be compared to peptide 8.6 through the use of fluorescence polarization.https://scholarscompass.vcu.edu/uresposters/1248/thumbnail.jp
