A Reliable and Valid Survey to Predict a Patient's Gagging Intensity.

Objectives: The aim of this study was to devise a reliable and valid survey to predict the intensity of someone's gag reflex.

Material And Methods: A 10-question Predictive Gagging Survey was created, refined, and tested on 59 undergraduate participants. The questions focused on risk factors and experiences that would indicate the presence and strength of someone's gag reflex.

An in vitro evaluation of the reliability and validity of an electronic pantograph by testing with five different articulators.

Statement Of Problem: The degree of reliability and validity of a new electronic pantographic instrument, the Cadiax Compact, has not been established.

Purpose: The purpose of this study was to test the reliability and validity of the electronic pantograph in calculating condylar settings for 5 different articulators (Denar D5A, Denar Mark II, Whip Mix 8500, Hanau Modular, and Panadent PCH).

Material And Methods: Pantograph sensors were mounted to each articulator with custom-made mounting devices.

Real-time detection of bacterial contamination in dynamic aqueous environments using optical sensors.

Here we describe on-line, real-time detection of waterborne bacteria using an optical sensor based on a starburst dendrimer film containing a lipophilic fluorophore. The sensor is constructed via covalent coupling between amine-terminated polyamidoamine dendrimer and silanized glass through an amide bond. The reporter molecule is embedded in the dendrimer layer through host-guest interaction.

Enhanced detection of live bacteria using a dendrimer thin film in an optical biosensor.

Here we describe the detection of live Pseudomonas aeruginosa using a sensing film containing a fourth-generation hydroxy-terminated polyamidoamine (PAMAM) dendrimer (i.e., G4-OH) and SYTOX Green fluorescent nucleic acid stain.

Optical sensors for detection of bacteria. 1. General concepts and initial development.

The concept of using immobilized nucleic acid stains as detection chemistry to fabricate optical bacterial sensors is first demonstrated. SYTO 13 (a green fluorescent cell stain) is used as the molecular recognition element and fluorescent reporter in the sensor. The sensor responds to aqueous and aerosolized bacterial samples in 15 and 30 min, respectively.
