هدف: به منظور دستیابی به سلول های پروژنیتوری-عصبی شبکیه، کشت سلول های اپیتلیوم رنگدانه دار شبکیه (rpe) انجام شد و سپس این کشت تحت تاثیر مایع آمنیوتیک انسانی (af) قرار گرفت. روش ها: سلول های rpe جداسازی شده از کره های چشم اجساد انسانی در سنین جنینی تا نوزادی (که بیش از 24 ساعت از زمان مرگ آنها نگذشته بود) از بانک چشم جمهوری اسلامی ایران تهیه شد و در محیط dmem/f12 غنی شده با 10% سرم جنینی گوساله...
The reaction of the carcinogenic electrophile Af-acetoxy-4acetylaminostilbene with methionine at neutral pH yielded /î-methylmercapto-4-acetylaminostilbene as the major product and 3-methylmercapto-4-acetylaminostilbene as a minor prod uct. Two other products were also formed. One of these had the apparent molecular weight (283) of a methylmercapto-4acetylaminostilbene; it was not identical wi...
We prove that AF-embeddability is a homotopy invariant in the class of separable exact C∗-algebras. This work was inspired by Spielberg’s work on homotopy invariance of AFembeddability and Dadarlat’s serial works on AF-embeddability of residually finite dimensional C∗-algebras.
introduction: electrophysiological studies have demonstrated a relationship between aging and atrioventricular (av) nodal conduction and refractoriness. the aim of the present study was to determine the effects of nodal aging on dynamic av nodal field potential recording during atrial fibrillation (af) in rabbit. methods: two groups of male new zealand rabbits (neonatal 2-week-olds and adult 12...
We report the results of a high energy spread SASE FEL experiment, the intermediary experiment linking the VISA I and VISA II projects. A highly chirped beam (1.7 %) was transported, without corrections of longitudinal aberrations in the ATF dogleg, and injected into the VISA undulator. The ouput radiation displayed an uncharacteristicly large bandwidth (12 %) with extremely stable lasing and m...
Background: Atrial fibrillation (AF) is one of the most common arrhythmias after coronary artery bypass graft (CABG) surgery. AF can result in hemodynamic instability, thromboembolic events, increase the perioperative myocardial infarction, congestive heart failure, stroke, more length of hospital stay (LOHS) and cost of treatment. The aim of this study was to evaluate the independent effect of...
Background Several scoring system have been developed with the aim to identify clinical deterioration among hospitalized patients and allocate resources in accordance with the degree of deterioration most without validation. The aim of the present study was to describe to which degree the system “Tidlig Opsporing af Kritisk Sygdom” (TOKS) is able to identify patients who either have or develop ...
