Effect of intrauterine copper on the nucleic acids, polysome pattern, and glycoprotein composition of the human endometrium
TL;DR: The modifications induced by the intrauterine release of copper in the macromolecular and glycoprotein composition of the proliferative and secretory human endometrium were studied and a significant decrease in the endometrial content of RNA in both phases of the menstrual cycle and drastic changes in the fucose-sialic acid ratios were observed.
Journal ArticleDOI
A novel fluorophotometric method for determination of hexosamines using pyridoxal and zinc (II) ion.
TL;DR: A novel fluorophotometric method for the detection and determination of amino sugars was established utilizing pyridoxal-HCl and Zn(II) ion, which was highly sensitive and higher than that obtained by the Elson-Morgan method.
