The effects of trimethylamine and ammonia on the buffering capacity of fish muscle and the change in the capacity during degradation were studied. The results obtained were as follows: 1) Trimethylamine and ammonia increased the buffering capacity on alkali side above pH 8 and 6 respectively. The latter was, although the effect was slight at lower pH range, the higher the pH the more effective ...

BACKGROUND The diagnostic utility of saliva is currently being explored in various branches of dentistry, remarkably in the field of caries research. This study was aimed to determine if assessment of salivary pH and buffering capacity would serve as reliable tools in risk prediction of early childhood caries (ECC). MATERIALS AND METHODS Paraffin-stimulated salivary samples were collected fro...

The objective of this article is to evaluate salivary flow rate, pH and buffering capacity of saliva in pregnant and non pregnant women. The present study was a comparison between 30 pregnant women in their third trimester and 30 non pregnant women, in the age group of 19-34 years. The salivary flow, pH, and buffering capacity was measured using Saliva-check BUFFER kit (GC Corporation). Both un...

Phillipsite tuff samples from Jebal Aritayn (Jordan) was treated chemically by acid, base, and salt and thermally at 200 and 400 oC. Both treated and untreated phillipsite samples were titrated with HCl and NaOH. The potentiometric titration curves showed that Jordanian phillipsite tuff exists in the base form (pH 8.5) and thus has a remarkable buffering capacity toward H. The effect of chemica...
