هدف:بررسی نتایج عمل تخلیه چشم ((evisceration و کارگذاری implant در بیماران مراجعه کننده به کلینیک مرکزی شهر در سالهای 1388و 1389 روش مطالعه:این مطالعه که از نوع توصیفی مقطعی بوده در 22 بیمار مراجعه کننده به کلینیک مرکزی شهر که تحت عمل evisceration با روش implant گذاری نوین قرار گرفته اند انجام شده است. بیماران بعد از ثبت اطلاعات دموگرافیک و سوابق چشم پزشکی و اطمینان از عدم دید کامل آنها(nlp) ...
the aim of this study is to compare the sensitometric properties of commonly used radiographic films processed with chemical solutions in different workload hospitals. the effect of different processing conditions on induced densities on radiologic films was investigated. two accessible double emulsions fuji and kodak films were exposed with 11-step wedge and processed with champion and cpac pr...
We report development of a model of retroviral gene transduction in high-density limb bud cell micromass culture. The replication competent avian retrovirus RCAS BP (A) carrying the human placental alkaline phosphatase gene (RCAS AP) was used as a marker for retroviral infection and spread. The final protocol balances the need to allow time for retroviral integration and gene transduction again...
OBJECTIVE Elevated levels of advanced oxidation protein products have been described in several chronic inflammatory diseases, like chronic renal insufficiency, rheumatoid arthritis, and atherosclerosis. Recent findings revealed that advanced oxidation protein products are inhibitors of the major high-density lipoprotein receptor, scavenger receptor class B, type 1 (SR-BI). Here, we investigate...
The degradation of different polyethylenes, LDPE, LLDPE, and HDPE, with and without antioxidants and at different oxygen concentrations in the polymer granulates have been studied in extrusion coating processing. The degradation was followed by On Line Rheometry, Size Exclusion Chromatography, Surface Oxidation Index measurements, and GC-MS Chromatography. The degradations starts in the extrude...
Changes in serum triglyceride and high density lipoprotein (HDL) cholesterol after a fatty meal have been studied in smokers and nonsmokers. Average serum triglyceride during the study was higher in smokers than in non-smokers. In non-smokers there was a rise in the HDL2/HDL3 cholesterol ratio after oral fat, but not in smokers. These findings are compatible with the hypothesis that smoking int...
To study the effect of aging on deformability of an erythrocyte, rheological measurement has been performed after exposure to a shear field in vitro. Deformability was evaluated with shear stress responsiveness and with critical elongation calculated from an exponential curve between an elongation index and shear stress. Human erythrocytes were classified according to their density by a centrif...
We calculate the phase diagram of amorphous solid water by performing molecular dynamics simulations using the extended simple point charge (SPC/E) model. Our simulations follow different paths in the phase diagram: isothermal compression/decompression, isochoric cooling/heating, and isobaric cooling/heating. We are able to identify low-density amorphous (LDA), high-density amorphous (HDA), and...
