In the title compound, [Y(C(2)H(5)N(3)O(2))(2)(H(2)O)(4)]Cl(3), the Y(3+) ion (site symmetry 2) is bonded to eight O atoms (arising from two O,O'-bidentate biuret mol-ecules and four water mol-ecules) in a distorted square-anti-prismatic arrangement. A network of N-H⋯O, N-H⋯Cl and O-H⋯Cl hydrogen bonds help to establish the packing, leading to a three-dimensional network. One of the chloride io...

An 80-year-old female patient presented in poor general condition, drowsy but responding to verbal commands. Medications given in the emergency room included cefotaxim, ranitidine, and vitamin K. Blood was sent for routine testing; serum total protein was 13.6 g/dL by the biuret method (reference interval, 6.1–7.9 g/dL). On visual inspection, the reaction mixture was brown instead of the usual ...

A decreased A/G ratio may indicate multiple myeloma, autoimmune disease, cirrhosis, or kidney disease. The patient’s electrophoretogram was normal, and subsequent immunofixation was negative, which ruled out monoclonal gammopathy. The SPE (Fig. 1) showed an albumin of 64.4% and normal A/G ratio, which suggests spurious hyperproteinemia. The patient was being treated with dextran (1 ). In the as...

THE presence of alcohol-soluble proteins in milk or cheese has been reported by several workers. Weidemann [1882] isolated from Emmenthal cheese by extraction with boiling ethyl alcohol a substance which he called caseoglutin. This was confirmed by Rose and Schulze [1884] and Benecke and Schulze [1887]. Winterstein and Th6ni [1902], Winterstein [1904] and Bisegger [1907], also working with Emme...

A previous study was undertaken to test the reaction of several quinones (p-benzoquinone; 2,5-dichloro and 2,6-dichloro p-benzoquinone; tetrachloro-p-benzoquinone; tetrachloro-o-benzoquinone; 2,5-dichloro-3,6-dihydroxy-p-benzoquinone; benz[a]anthracene-7,12-dione) with bovine serum albumin (BSA). From this study, we have devised a spectrophotometric method for determination of total proteins. T...

Fleming (1) in 1922 reported the occurrence of a bacteriolytic principle, lysozyme, in egg white, tears, and other animal fluids. Since then much work has been devoted to its bacteriological behavior, but the only work of importance on its purification and chemical nature was that of Wolff (2). Wolff precipitated diluted egg white with colloidal iron, evaporated the filtrate to a small volume, ...
