RECORDING PROJECT: THE COMPLETE (PUBLISHED) PIANO WORKS OF ROBERT HELPS

This recording represents the complete solo piano works of Robert Helps (1928-2001). As of this writing (March, 2008), approx.120 minutes of Helps' solo piano music has been published, all of which is included on the Digital Media (CD). This project includes the following works: Trois Hommages, Quartet, Nocturne, Valse Mirage, In Retrospect, Three Etudes, Portrait, Three Etudes for the Left Hand, Starscape, Recollections, Shall We Dance and Image. (His few remaining pieces are officially "pending publication" and are therefore not included in this project.) Robert Helps, American pianist and composer, enjoyed a successful career on both fronts, teaching at such institutions as San Francisco Conservatory, Stanford University, the University of California, Berkeley, the New England Conservatory, the Manhattan School of Music and Princeton University. Helps, never the recipient of a university or conservatory degree, received private instruction from pianist Abby Whiteside and composer Roger Sessions. His recording of the Sessions' Sonatas is considered to be their benchmark performance. As a composer, he received commission and awards from the American Academy of Arts and Letters, the Ford Foundation, the Guggenheim Foundation and the National Endowment for the Arts. Helps' compositions were anachronistic in style: his compositional style ranges from Post-Impressionism, Neo­ Romanticsim and early 20th century Atonalism, although he never engaged in serial practices. Since his death in 2001, the Robert Helps Trust has been established at the University of South Florida. Funds are being used to support the continued publishing of his scores. The Robert Helps International Composition Competition and Festival was established in 2005.

The Application of an Exogenous Linear and Radial Electrical Field to an In Vitro Chronic Diabetic Ulcer Model for Evaluation as a Potential Treatment

Chronic diabetic ulcers affect approximately 15% of patients with diabetes worldwide. Currently, applied electric fields are being investigated as a reliable and cost-effective treatment. This in vitro study aimed to determine the effects of a constant and spatially variable electric field on three factors: endothelial cell migration, proliferation, and angiogenic gene expression. Results for a constant electric field of 0.01 V demonstrated that migration at short time points increased 20-fold and proliferation at long time points increased by a factor of 1.40. Results for a spatially variable electric field did not increase directional migration, but increased proliferation by a factor of 1.39 and by a factor of 1.55 after application of 1.00 V and 0.01 V, respectively. Both constant and spatially variable applied fields increased angiogenic gene expression. Future research that explores a narrower range of intensity levels may more clearly identify the optimal design specifications of a spatially variable electric field.

Fabrication of Poly (D,L-Lactic-Co-Glycolic Acid) Microparticles for Improved Human Papillomavirus Vaccine Delivery

Human papillomavirus (HPV) is the leading cause of cervical cancer and the most prevalent sexually transmitted disease worldwide. HPV vaccines require a multi-dose regimen to provide immunity, contributing to low patient compliance. We addressed this problem by formulating biodegradable poly(D,L-lactic-co-glycolic acid) (PLGA) microparticles and assessing their viability for use in controlled-release vaccines. We hypothesized that we could alter fabrication parameters to produce 1-10 μm microparticles in order to encapsulate ovalbumin (OVA) and HPV virus-like particles (VLPs). Microparticles were fabricated using a double emulsion method and used to elicit an immune response in JAWSII cells. Our results contribute to knowledge of vaccine delivery mechanisms and controlled-release technology, and could contribute to the creation of a viable controlled-release HPV vaccine.
