Cord Blood Lipid Profile in Premature, Near-Term and Term Newborn Infants

Introduction: The fetus needs a considerable amount of cholesterol for the development of tissues and organs.  Studies have suggested that genetic and environmental factors influence the composition of cord blood lipoproteins.  In this study, we aim to assess the effect of gestational age, sex and birth weight on the cord blood lipoproteins. Methods: We collected umbilical cord blood samples fr...

Incorporation of acetate into fatty acids and lecithin by lung slices from fetal and newborn lambs.

Incorporation of acetate-1-(14)C into phospholipids and fatty acids by lung slices from fetal and newborn lambs and from ewes was studied in vitro. The distribution of radioactivity in the fatty acids of neutral lipids, phospholipids, and lecithin was determined. Acetate-1-(14)C was incorporated into myristic, palmitic, and C(18) fatty acids. Of the lecithin fatty acids, myristic and palmitic w...

the effects of keyword and context methods on pronunciation and receptive/ productive vocabulary of low-intermediate iranian efl learners: short-term and long-term memory in focus

از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...

The effect of prolactin on the lecithin content of fetal rabbit lung.

1 mg ovine prolactin was injected intramuscularly into rabbit fetuses (24th day of gestation) located in one of the two uterine horns exposed by laparotomy (n = 12). Fetuses in the other uterine horn were injected with an identical volume of vector and served as controls (n = 13). 2 days later the fetuses were removed by a second laparotomy and sacrificed. Analysis of lung tissue composition yi...
