Case Studies For Dentistry®: Development Of A Tool To Author Interactive, Multimedia, Computer-Based Patient Simulations, Louis M. Abbey, Pamela Arnold, Lucy Halunko, Mary Beth Huneke, Stacie Lee

Oral and Maxillofacial Surgery Publications

Computer-based patient simulations have been used to enhance the dental curriculum since the 1980s. This article describes the development of CASE STUDIES for Dentistry (CSD), a patient case simulation building template, developed at Virginia Commonwealth University, with which authors who have no programming expertise can create realistic, effective, interactive multimedia patient simulations by entering their own information and images into a straightforward, fill in the blanks interface. This program was written with Authorware, by Macromedia Inc. Design considerations included emphasis on information collection and analysis, synthesis of collected information, hypothesis proposal and testing, diagnosis, and treatment planning. The program consists …

Bekm-1 Is A Herg-Specific Toxin That Shares The Structure With Chtx But The Mechanism Of Action With Ergtx1, Mei Zhang, Yuliya V. Korolkova, Jie Liu, Min Jiang, Eugene V. Grishin, Gea-Ny Tseng

Physiology and Biophysics Publications

ABSTRACT

Peptide toxins with disulfide-stabilized structures have been used as molecular calipers to probe the outer vestibule structure of K channels. We want to apply this approach to the human ether-a-go-go-related gene (HERG) channel, whose outer vestibule is unique in structure and function among voltage-gated K channels. Our focus here is BeKm-1, a HERG-specific peptide toxin that can suppress HERG in the low nM concentration range. Although BeKm-1 shares the three-dimensional scaffold with the well-studied charybdotoxin, the two use different mechanisms in suppressing currents through their target K channels. BeKm-1 binds near, but not inside, the HERG pore, and it …

BACKGROUND

In preclinical and phase 2 studies, adefovir dipivoxil demonstrated potent activity against hepatitis B virus (HBV), including lamivudine-resistant strains.

METHODS

We randomly assigned 515 patients with chronic hepatitis B who were positive for hepatitis B e antigen (HBeAg) to receive 10 mg of adefovir dipivoxil (172 patients), 30 mg of adefovir dipivoxil (173), or placebo (170) daily for 48 weeks. The primary end point was histologic improvement in the 10-mg group as compared with the placebo group.

RESULTS

After 48 weeks of treatment, significantly more patients who received 10 mg or 30 mg of adefovir dipivoxil per day than …

The Ca2+ Dynamics Of Isolated Mouse Β-Cells And Islets: Implications For Mathematical Models, Min Zhang, Paula Goforth, Richard Bertram, Arthur Sherman, Leslie S. Satin

Pharmacology and Toxicology Publications

ABSTRACT

[Ca²⁺]_i and electrical activity were compared in isolated β-cells and islets using standard techniques. In islets, raising glucose caused a decrease in [Ca²⁺]_i followed by a plateau and then fast (2–3 min⁻¹), slow (0.2–0.8 min⁻¹), or a mixture of fast and slow [Ca²⁺]_i oscillations. In β-cells, glucose transiently decreased and then increased [Ca²⁺]_i, but no islet-like oscillations occurred. Simultaneous recordings of [Ca²⁺]_i and electrical activity suggested that differences in [Ca²⁺]_i signaling are due to …
