Macroprolactin detection by precipitation with protein A-sepharose: a rapid screening method compared with polyethylene glycol precipitation.
within 21 days. The likelihood ratio for a negative result [(1 sensitivity)/specificity] was 0.59 for birth within 7 days, 0.68 for birth within 14 days, and 0.53 for birth within 21 days. The data in Table 1 are similar to those obtained in previous studies using the ELISA-based assay. Joffe et al. (1 ) reported a NPV of 99.6% and a PPV of 9.1% for 243 patients who delivered within 7 days with...
متن کاملthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولHyperprolactinemia: new assay more specific for the monomeric form does not eliminate screening for macroprolactin with polyethylene glycol precipitation.
Prolactin presents important size heterogeneity in terms of circulating molecular forms. Besides the monomer (23kDa), which predominates in healthy subjects as well as in patients with prolactinoma, high molecular forms are also present in low concentrations (1). These high molecular forms include 50 kDa dimers (big prolactin) and also forms with even larger molecular weights (MW>150 kDa), know...
متن کاملUltrafiltration – an alternative method to polyethylene glycol precipitation for macroprolactin detection
INTRODUCTION The aim of the study was to evaluate two methods of macroprolactin (MaPRL) detection - precipitation with polyethylene glycol (PEG) and ultrafiltration and to compare these techniques with "gold standard" - gel filtration chromatography (GFC). MATERIAL AND METHODS The study was conducted on 245 patients - 45 with organic and 200 with functional hyperprolactinaemia. In all the sub...
متن کاملthe survey of the virtual higher education in iran and the ways of its development and improvement
این پژوهش با هدف "بررسی وضعیت موجود آموزش عالی مجازی در ایران و راههای توسعه و ارتقای آن " و با روش توصیفی-تحلیلی و پیمایشی صورت پذیرفته است. بررسی اسنادو مدارک موجود در زمینه آموزش مجازی نشان داد تعداد دانشجویان و مقاطع تحصیلی و رشته محل های دوره های الکترونیکی چندان مطلوب نبوده و از نظر کیفی نیز وضعیت شاخص خدمات آموزشی اساتید و وضعیت شبکه اینترنت در محیط آموزش مجازی نامطلوب است.
