purpose : to investigate the application of mitomycin-c 0.02% (mmc) in the photorefractive keratectomy (prk) procedure in correcting regressed myopia methods : eighteen eyes of 11 patients with a spherical equivalent (se) of less than -5 diopters (d) who had undergone laser in situ keratomileusis (lasik) more than 2 years before were operated on. at the end of the prk procedure, mmc was applied...
background:breast cancer remains the most common and second lethal cancer in females. her-2/neu is one of the most important amplified oncogene in breast cancer. the amplification of her-2 is correlated with decreased survival, metastasis, and early recurrence. the amplification of her-2/neu gene and synthesis of the protein are reported in 10%-34% of breast cancer cases associated with tumor ...
background the incidence rate of gastric cancer in western countries has shown a remarkable decline in the recent years while it is still the most common cancer among males in iran. the proto-oncogene myc, located at 8q24.1, regulates almost 15% of human genes and is activated in 20% of all tumors. the amplification of myc and overexpression of its protein product are observed in 15 - 30% of ga...
in this study, doxycycline hyclate release behavior from in situ forming drug delivery systems investigated. these systems based on poly()lactide-co-glycolide)(50:50 dissolved in n-methyl-2-pyrrolidone that were evaluated in different concentrations. these systems are useful for local treatment of periodontal diseases. uv spectroscopy is used to determine drug concentration in release medium. a...
In studying of the in situ gravitational concentration process part feature for placer, the technological ability to transform the in situ massif placer structure is evident. The two main processes involved in altering the massif in situ have been examined and outlined in detail. The in situ disintegration of massif material results in a new massif gravitational stratification structure. Regula...
STUDY DESIGN Retrospective, observational, single-center study. PURPOSE To investigate the long-term outcomes of in situ fusion procedures for treating dysplastic spondylolisthesis. OVERVIEW OF LITERATURE In situ fusion performed in patients with dysplastic spondylolisthesis avoids the development of nerve complications. METHODS In total, 12 of 28 patients who underwent in situ fusion for...
Background: Spondylolysis and spondylolisthesis can be associated with significant low back pain, especially in physically active adolescents. Non-operative management is usually successful in improving symptoms, but surgical intervention is occasionally required. The aim of this study was to determine the effect of in situ posterolateral fusion in the treatment of refractory cases with spondyl...
این آزمایش به منظور تعیین ترکیب شیمیایی و تجزیه پذیری 12 واریته دانه غلات (6 واریته گندم، 3 واریته ذرت و 3 واریته ارزن) به روش in situ به اجرا درآمد. در این آزمایش از 6 راس گوسفند نائینی با وزن متوسط 40 کیلوگرم استفاده شد. دانه های اسیاب شده(2 میلیمتر) در زمانهای 0 ، 2 ، 4 ، 8 ، 12 و 24 درون شکمبه قرار گرفتند. اثرات غله ها و واریته های هر غله در قالب طرح کاملا" تصادفی آنالیز شد و جهت بررسی اثرا...
High-grade dysplastic spondylolisthesis is extremely rare and always involves the L5-S1 level. It is attributed to congenital dysplasia of the superior articular process of the sacrum. It can remain asymptomatic for a long time and can progress to a more severe grade of olisthesis and spondyloptosis. Surgical treatment has varied from posterior-only in situ fusion to anterior and posterior fusi...
