Previous studies have shown that momentary contact between a methylmethacrylate intraocular lens and the corneal endothelial cells results in extensive cell damage. This contact damage is reduced by coating the pseudophake with various solutions prior to contact with the endothelium.

Nosocomial infections due to bacteria have serious implications on the health and recovery of patients in a variety of medical scenarios. Since bacterial contamination on medical devices contributes to the majority of nosocomical infections, there is a need for redesigning the surfaces of medical devices, such as catheters and tracheal tubes, to resist the binding of bacteria. In this work, pol...

Electron paramagnetic resonance (EPR) spectroscopy was applied to study the paramagnetic species formed from styrene, 1,1-diphenylethylene, α-methylstyrene, β-methylstyrene and methylmethacrylate adsorbed on amorphous silica gel after γ-irradiation at 77K. Radicals formed by the hydrogen atom addition at the vinyl group of the monomers were observed in all samples. The hydrogen atoms were shown...

Magnetic head fabrication for .100 Gbit/in. areal density requires minimum lithographic feature size ,0.15 mm, with aspect ratios of 8:1–10:1. Electron-beam lithography can provide adequate resolution for research and development of magnetic heads, and at 100 kV can provide greater than 10:1 aspect ratios in 1–3 mm thick single-layer resist poly~methylmethacrylate!. Poly ~methylmethacrylate! ~P...

Objective: We stress out the rare anomaly of a cervical Hemivertebra associated with adjacent level radiculitis due to degeneration. Results: We present a case of a 58 years old female with spontaneous finding of a cervical hemivertebra at the level C5. The patient suffered from cervical nerve root compression syndrome at the level C6/7 at the convex side of the scoliosis. She was treated by a ...

This article reports on a 60-year-old woman who had an allergic reaction to methylmethacrylate self-curing acrylic resin during orthodontic treatment. A localized hypersensitive reaction appeared on the palate after an orthodontic retainer was placed. Samples of the acrylic were removed and analyzed with gas chromatography to evaluate the residual monomer level. The residual monomer content was...

We report on the fabrication of crossed-dipole resonant filters by direct-write electron-beam and nanoimprint lithographies. Such structures have been used as spectrally selective components at visible, microwave, and infrared wavelengths. Imprinting is accomplished in a modified commercial hot press at 155 °C. The replica is then etched in oxygen plasma and developed in chlorobenzene to select...
