Determination of vaginal pH by pH indicator strip and by pH micro electrode.
Vaginal pH measurement is a screening method of vaginal infection in pregnancy. We tested two different methods of pH determination. In freshly taken vaginal fluid measurements were carried out with special pH indicator strips and pH micro glass electrode. About 100 microliters of vaginal fluid is enough when pH indicator strips are used, and 200 microliters when the micro electrode is used. Th...
متن کاملA potentiometric disposable sensor strip for measuring pH in saliva
In this paper, the preparation of a potentiometric strip for pH monitoring in saliva samples is reported. The potentiometric strip consists of a solid contact pH-selective and of a solidcontact ionogel reference electrode prepared on a dual screen printed substrate. The screen printing protocols, i.e., type of inks and number of deposits, were adjusted to relatively improve the batch reproducib...
متن کاملComputational Tools for Interpreting Ion Channel pH-Dependence
Activity in many biological systems is mediated by pH, involving proton titratable groups with pKas in the relevant pH range. Experimental analysis of pH-dependence in proteins focusses on particular sidechains, often with mutagenesis of histidine, due to its pKa near to neutral pH. The key question for algorithms that predict pKas is whether they are sufficiently accurate to effectively narrow...
متن کاملDiagnostic accuracy of pH monitoring in gastro-oesophageal reflux.
One hundred and eleven children admitted with suspected gastro-oesophageal reflux were studied, with 24 hour oesophageal pH monitoring as the first line of investigation. Barium swallow examination, or oesophagoscopy, or both, were carried out only in children with abnormal pH, who subsequently had a trial of 1-12 months medical treatment. All patients were followed up for eight months to two y...
متن کاملUnsedated peroral wireless pH capsule placement vs. standard pH testing: A randomized study and cost analysis
BACKGROUND Wireless capsule pH-metry (WC) is better tolerated than standard nasal pH catheter (SC), but endoscopic placement is expensive. AIMS to confirm that non-endoscopic peroral manometric placement of WC is as effective and better tolerated than SC and to perform a cost analysis of the available esophageal pH-metry methods. METHODS Randomized trial at 2 centers. Patients referred for ...
