The interaction between copovidone and Carbopol 907 is pH dependent. When the pH of an aqueous solution fell below pH 4.5, a water-insoluble complex began to form and precipitate. This complex resulted from a hydrogen-bond-induced interaction between the carboxylic groups in Carbopol 907 and the carbonyl groups of N-vinylpyrrolidone repeat units in copovidone. Consisting of these two polymers a...

BACKGROUND The aim of this study was to validate the Omron HEM-907 blood pressure (BP) measuring device according to the international validation protocol. DESIGN The international validation protocol is divided into two phases: the first phase is performed on 15 selected subjects and if the device passes this phase, 18 more subjects are selected making a total number of 33 subjects on which ...

A new, simple, and rapid assay for conjugated bilirubin that does not require serum-matrix standards was developed by using the enzyme bilirubin oxidase (EC 1.3.3.5). This procedure can also be modified to measure total bilirubin. Measurements from these assays were compared with results obtained with the Sigma 605 (Jendrassik-Gróf method), Sigma 550/551 (Walters-Gerarde method), and Kodak Ekta...

OBJECTIVE To evaluate the effect of the fetal head station at attempted operative vaginal delivery (aOVD), and specifically midpelvic or low aOVD, on female and male sexual function and symptoms of postpartum depression (PPD) at 6 months. DESIGN Prospective population-based cohort study. SETTING 1,941 women with singleton term fetuses in vertex presentation with midpelvic or low aOVD betwee...
