Objectives: The purpose of this study was to use transcranial 2- and 3-dimensional sonography with the Virtual Organ computer-aided analysis (GE Healthcare, Milwaukee, WI) technique to observe the morphologic characteristics of the hippocampal formation and to analyze its correlation with the corrected gestational age.
Methods: Transcranial sonography was performed from the sagittal plane of the anterior fontanel to the sagittal plane of the posterior horn of the lateral ventricle. The morphologic characteristics of the hippocampal formation in 183 singleton neonates with a corrected gestational age of 32 to 43 weeks were observed.
This study evaluated the impact of dissolved organic matter (DOM) of varying molecule weights (MWs) on long-term exposure to Cu and Pb in Chlorella pyrenoidosa. Citric acid, fulvic acid, and humic acid, in the order of increasing MWs, were selected to represent DOM. The results showed that DOM with larger MWs had stronger inhibitory effects on the bioavailability of Cu to algae.
