According to the nomenclature rules of IUPAC the dihedral angle describing the relative orienta­ tions of the two ends of the molecule should be de­ fined as 0° in 1 a and as 180° in lb [3], We refer to l a as the syn conformer and to lb as anti. A mi­ crowave study of gaseous hydroxylamine has shown that the predominant conformer is syn [4]. A microwave study of O-methyl hydroxylamine [5], and...

While the high school dropout rate has shown steady improvement during the last decade, it is still unacceptably high among students of color. They make up a large percentage of the 3.3 million youths who have not completed H.S.; however, they are the least likely to take, complete, and pass GED tests. Concept mapping could offer for young urban adult learners the opportunity to make meaningful...

AIM To optimize the hepatobiliary phase delay time (HBP-DT) of Gd-EOB-DTPA-enhanced magnetic resonance imaging (GED-MRI) for more efficient identification of hepatocellular carcinoma (HCC) occurring in different degrees of cirrhosis assessed by Child-Pugh (CP) score. METHODS The liver parenchyma signal intensity (LPSI), the liver parenchyma (LP)/HCC signal ratios, and the visibility of HCC at...

Multiple phosphorylation sites of Drp1 have been characterized for their functional importance. However, the functional consequence of GSK3beta-mediated phosphorylation of Drp1 remains unclear. In this report, we pinpointed 11 Serine/Threonine sites spanning from residue 634~736 of the GED domain and robustly confirmed Drp1 Ser693 as a novel GSK3beta phosphorylation site. Our results suggest th...
