BACKGROUND The purpose of this in-vitro study was to investigate the potential of biofilm removal in interproximal tooth regions using intervallic cleaning with an oral irrigator or a sonic toothbrush. METHODS Three-species biofilms (Streptococcus mutans (OMZ 918), Streptococcus oralis SK 248 (OMZ 60), Actinomyces naeslundii (OMZ 745)) were grown on hydroxyapatite discs for 3 days in culture ...

The impact of curcumin-loaded nanodroplets on the properties commercial salad dressings was examined. Nanoemulsions were formulated using a plant-based oil (medium chain triglycerides, MCT) and either (Quillaja saponaria, QS) or animal-based (whey protein isolate, WPI) emulsifier. Curcumin-loaded nanoemulsions produced by microfluidization contained small anionic droplets: d32 = 0.28 0.11 μm ζ ...

This study deals with the design and comprehensive evaluation of novel hydrogels based on whey protein isolate (WPI) for tissue regeneration. So far, WPI has been considered mainly as a food industry by-product there are very few reports application in engineering (TE). In this work, WPI-based were modified bioactive glass (BG), which is commonly used bone substitute material. Ready-to-use, ste...

A new method to quantify changes in El Niño–Southern Oscillation (ENSO) variability is presented, using the overlap between probability distributions of the wavelet spectrum as measured by the wavelet probability index (WPI). Examples are provided using long integrations of three coupled climate models. When subsets of Niño-3.4 time series are compared, the width of the confidence interval on W...

The effects of heat-induced denaturation and subsequent aggregation of whey protein isolate (WPI) solutions on the rate of enzymatic hydrolysis was investigated. Both heated (60 °C, 15 min; 65 °C, 5 and 15 min; 70 °C, 5 and 15 min, 75 °C, 5 and 15 min; 80 °C, 10 min) and unheated WPI solutions (100 g L(-1) protein) were incubated with a commercial proteolytic enzyme preparation, Corolase PP, un...

Helicobacter pylori infection causes severe dysplasia manifested as gastrointestinal intraepithelial neoplasia (GIN) after 28 weeks post H. pylori infection (WPI) in cancer-prone, hypergastrinemic male INS-GAS mice. We examined the efficacy of the NSAID sulindac (400 ppm in drinking water) alone, the CCK2/gastrin receptor antagonist YM022 (45 mg/kg/week) alone, and sulindac or YM022 combined wi...

Although Wireless Local Area Networks (WLANs) are widely used in many settings little work has been done in studying their impact and benefits. This study provides empirical indicators on the performance of the WLANs implemented on Malaysian Institutions of Higher Learning Our research adopted Deming’s P-D-C-A Model and modified it to PlanImplement-Control-Evaluate (P-I-C-E) in establishing a p...

The effect of liver fluke infection (Fasciola hepatica) on ion transport in the rat proximal colon was evaluated with electrophysiological methods using an Ussing apparatus. Rats were orally infected with F. hepatica metacercariae. The experimental groups of rats at 4 weeks post-infection (wpi) were in the acute stage of fasciolosis, while those at 7, 10 and 13 wpi represented the chronic phase...

This paper introduces a new similarity measure called weighted profile intersection (WPI) for profile-based authorship attribution (PBAA). Authorship attribution (AA) is the task of determining which, from a set of candidate authors, wrote a given document. Under PBAA an author’s profile is created by combining information extracted from sample documents written by the author of interest. An un...
