Context: Mini-medical school programs are designed to give participants, usually high school students, a more realistic perception of medicine and to leave students with a stronger desire to pursue a career in medicine.

Objective: To determine if the annual High School Mini-Medical School program hosted by the West Virginia School of Osteopathic Medicine increased interest in osteopathic medicine among high school students.

Design: A survey was conducted before and after the program to test the program's effectiveness.

L929 murine fibroblast cells were exposed to radiofrequency (RF) radiation from a time division multiple access wireless phone operating at 835 MHz frequency to determine the effect of RF-radiation energy emitted by wireless phones on ornithine decarboxylase (ODC) activity in cultured cells. Exposure was for 8 h to an average specific absorption rate (SAR) from <1 W/kg up to 15 W/kg. After exposure, cells were harvested and ODC activity was measured.

Ornithine decarboxylase (ODC) activity is used widely as a biomarker for tumor promotion in animal model systems. Several previous studies have reported increases in ODC activity in tissues of rats exposed to 60 Hz magnetic fields. The goals of this study were to confirm these findings and to determine whether ODC activity is increased in tissues of animals exposed to magnetic fields containing complex metrics.

Fertilized white leghorn eggs were exposed to a 4 micro-Tesla (microT) 60 Hz horizontal magnetic field for 15, 18, 23 and 28 h. After exposure to the magnetic field, the embryos were isolated and assayed for ornithine decarboxylase (ODC) activity. ODC activity in magnetic field-exposed embryos was compared to ODC activity in sham-exposed embryos.
