Rabbits received nonpenetrating central corneal knife wounds. Immediately after wounding, a single 2.5 or 5.0 micron dose of mesodermal growth factor (MGF) was applied topically to the wound. Controls were treated with saline. Electron microscopic studies compared the healing responses of the control and treated animals over a 7-day period. MGF was a potent(More)
PURPOSE Cytokines have been implicated in corneal inflammatory diseases. The authors sought to determine if corneal diseases with different patterns of inflammation are accompanied by characteristic patterns of cytokine expression. METHODS The authors used reverse transcription-polymerase chain reaction to detect mRNA for 12 specific cytokines from(More)
There is a need for safer and improved methods for non-invasive imaging of the gastrointestinal tract. Modalities based on X-ray radiation, magnetic resonance and ultrasound suffer from limitations with respect to safety, accessibility or lack of adequate contrast. Functional intestinal imaging of dynamic gut processes has not been practical using existing(More)
When retinal disparity exceeds the limits for fusion, the resulting images are perceived as diplopic. In a stereo test that allowed comparison of crossed and uncrossed disparity sensitivities, 74% of the subjects perceived convergent disparities more readily than divergent disparities. This asymmetric sensitivity to disparity did not appear to be related to(More)
Hypoxia is a recognized characteristic of tumors that influences efficacy of radiotherapy (RT). Photoacoustic imaging (PAI) is a relatively new imaging technique that exploits the optical characteristics of hemoglobin to provide information on tissue oxygenation. In the present study, PAI based measures of tumor oxygen saturation (%sO2) were compared to(More)
Determinants of safer sexual behaviors among HIV-infected adult men with hemophilia were examined. A model was proposed that personal adjustment, communication skills, self-efficacy, and perceived advantages of condom use would influence safer sex practices. The model was tested with 181 men with hemophilia and HIV infection from 27 hemophilia treatment(More)
