Rhabdomyomatous well-differentiated esophageal liposarcomas are extremely rare. As of August 2016, only one other such case has been reported in the English-language medical literature. Liposarcomas in general are one of the most common soft tissue neoplasms in adults, but the incidence of primary esophageal liposarcomas is exceptionally low. There have been only 42 reported cases of primary li...

The growth of L-fibroblasts in diffusion chambers implanted intraperitoneally in C3H mice was inhibited by "hyperimmunizing" the host with L-fibroblasts; no significant inhibition was found while reactions analogous to first-set and second-set rejections presumably were occurring in the host outside the diffusion chamber. The serum from "hyperimmunized" C3H mice contained a diffusible (soluble)...

The Boyden chamber assay, originally introduced by Boyden for the analysis of leukocyte chemotaxis, is based on a chamber of two medium-filled compartments separated by a microporous membrane. In general, cells are placed in the upper compartment and are allowed to migrate through the pores of the membrane into the lower compartment, in which chemotactic agents are present. After an appropriate...

background : in recent years tissue engineering developed to replace or repair damaged tissues using cell and biomaterial. one of the most important fields of tissue engineering is simulation of in vivo micro environment of body tissues. this study aimed to develop culture chamber and cell biomaterial sheet engineering for the reconstruction of cartilage tissue. methods : stainless steel cultur...

Secondary intraocular lens implantation after cataract surgery done in University Hospital between 1983 to 1993 were reviewed. Thirty three patients (37 eyes) underwent secondary intraocular lens implantation during this period. Twenty four eyes had secondary anterior chamber lens implantation while 13 had posterior chamber lens implantation. There was no case of secondary posterior scleral fix...

Equations are described to derive the true anterior chamber dimensions of an eye from a photograph of its optical section. If the surface of the eye is assumed to be spherical, the three-dimensional coordinates of rays emanating from the anterior chamber to a camera can be transformed to two-dimensional coordinates on a plane, which contains rays both inside and outside of the "eye." The actual...

introduction for dose measurement in megavoltage (mv) photon beams with ion chambers, the effect of volume occupied by the air cavity is not negligible. therefore, the result of measurement should be corrected with a displacement perturbation correction factor (pdis) or using an effective point of measurement (epom). the aim of this study is to calculate the epom for cylindrical ion chamber and...

BACKGROUND Despite the technological evolution of the implantable defibrillator, one of the questions that remains is the possible benefit of the dual chamber versus single chamber implantable cardioverter defibrillator (ICD) in reducing inappropriate shocks. OBJECTIVE To evaluate which type of device provides fewer inappropriate shocks (dual chamber versus single chamber) in patients with im...
