Rupture of small blood vessels is a primary feature of the tissue injury associated with shock wave lithotripsy (SWL), and cavitation has been implicated as a potential mechanism. To improve our understanding of the damage mechanism, dynamics of SWL-induced bubbles in constrained media were investigated. Silicone tubing and cellulose hollow fibers (i.d.=0.2 ~ 1.5 mm) were used to fabricate vess...

PURPOSE To present the finding of tiny silicone oil droplets in 15 eyes of 15 patients after intravitreal injections of an anti-vascular endothelial growth factor agent or triamcinolone acetonide and to discuss the likely source of silicone oil. METHODS In an observational case series, charts of patients who had undergone intravitreal injections by one surgeon were reviewed retrospectively. T...

Abstract The main component of Silicone-based heat transfer fluids is modified silicone oil. high and low using temperature silicone-based better than hydrocarbon organic fluids. raising the maximum means that it can obtain higher steam in process system, power generation efficiency turbine will be improved remarkably if are used parabolic through solar system. It also increase a thermal plant,...

there are many studies about epidural fibrosis after surgical manipulation of the spine. we have studied formation of the post laminectomy epidural fibrosis after application of two materials (silicone and teflon) in this report. this expriment is on two groups of rats. two separated laminectomies were done in each rat, one serving as control while in the other laminectomy spaces silicone was u...

AbstractIntroduction Silicone gel breast implants are used for breast reconstruction post mastectomy. In the event of cancer recurrence, the radiation oncologists are forced to irradiate through the prosthesis device. Due to prosthesis higher atomic number dose perturbations occur during treatment. This study determined the influence of silicone gel thickness on the photon beam distribution. Ma...

Because of the increasing trend of body contour enhancements with injections, implants, and fillers, clinicians should be on high alert for the possibility of silicone-induced hypercalcemia as one of the differential diagnoses in a patient with history of silicone use. Hypercalcemia as a result of silicone injections has been reported, and there is concern that there will be more cases given th...

PURPOSE This tutorial demonstrates the effects of tubing length and coupling type (i.e., foam tip or personal earmold) on hearing threshold and real-ear-to-coupler difference (RECD) measures. METHOD Hearing thresholds from 0.25 kHz through 8 kHz are reported at various tubing lengths for 28 normal-hearing adults between the ages of 22 and 31 years. RECD values are reported for 14 of the adult...

A hollow-cathode microplasma modified the lumenal surface of small-diameter polyethylene (PE) tubing. A microwave cavity diagnostic was used to measure the density of the microplasma. Plasma light output was observed with a monochromator at various positions along the PE tube to assess uniformity. Treatment effectiveness was evaluated by measuring the variation in capillary rise at various posi...

The continuous production and harvest of uncontaminated cells for periods of several months are a major requirement inthe design of a suitable culture system. Many continuous-culture units have been reported previously (1, 2), and some units are now commercially available. However, in these units, rubber, metals, and other sources of potentially toxic extractives are not prevented from direct c...
