The aim of this in vitro study was to determine the maximum inhibitory dilution (MID) of four cetylpyridinium chloride (CPC)-based mouthwashes: CPC+Propolis, CPC+Malva, CPC+Eucaliptol+Juá+Romã+Propolis (Natural Honey) and CPC (Cepacol), against 28 Staphylococcus aureus field strains, using the agar dilution method. Decimal dilutions ranging from 1/10 to 1/655,360 were prepared and added to Muel...

BACKGROUND In April 2009, an A(H1N1) influenza virus of swine lineage was detected in humans in the USA, and in just over a month has infected over 10,000 people in more than 40 countries. OBJECTIVES To determine the performance of the Binax Now, BD Directigen EZ, and the Quidel QuickVue influenza rapid point-of-care (POC) tests for the detection of the recently emerged swine lineage A(H1N1) ...

As mergers become increasingly important in the financial services industry, the need for proper sensitivity analysis to assess the financial impact of the merger is essential. Unlike industrial mergers, there is almost always initial dilution in a bank merger. This is because of the homogenous nature of bank P/E ratios and the high premium over book value that is typically paid. The problem of...

Infiltration and extravasation are risks of intravenous administration therapy involving unintended leakage of solution into the surrounding tissue. Consequences range from local irritation to amputation. While immediate action using appropriate measures (ie, dilution, extraction, antidotes, and supportive treatments) can decrease the need for surgical intervention, many injuries may be prevent...

The serial-dilution assay is a standard microbiological method for estimating the density of organisms in a solution. The commonly used interval-estimation procedures of Woodward and deMan are described and compared. A new method for the calculation of two-sided confidence intervals, which is superior to the standard procedures, is presented. The computations are illustrated for a decimal dilut...
