dental caries/potato

The opening-closing rhythms of the subelytral cavity and associated gas exchange patterns were monitored in diapausing Leptinotarsa decemlineata beetles. Measurements were made by means of a flow-through CO2 analyser and a coulometric respirometer. Under the elytra of these beetles there is a more

The effects of repeated retrogradation (RR) treatment on the structural characteristics and in vitro digestibility of waxy potato starch were investigated. The cycling times of RR ranging from 1 to 5 were designated as RR-1, RR-2, RR-3, RR-4, and RR-5, respectively. A maximum SDS content (40.41%)

Fusarium dry rot of potato can be caused by several species of Fusarium, but F. sambucinum is considered the primary cause in stored potatoes in North America and Europe (2). Potato tubers of cvs. Shepody and Russet Burbank with severe dry rot were collected from a commercial processing storage

Four detection techniques, three of which gave reliable identification of the virus particles, were used to locate potato leafroll virus (PLRV) in the alimentary canal of its main aphid vector, Myzus persicae Sulz: immunofluorescence on cryostat sections, conventional transmission electron

The presence of carbohydrates and organic acids was monitored in the oral cavity over a 3-hour period following the ingestion of six foods containing cooked starch (popcorn, potato chips, corn flakes, bread stick, hard pretzel and wheat cracker) and compared to a food containing sugar

Five well-characterized foods were used to compare two systems for estimating the cariogenic potential of food: human plaque-acidity using interdental metallic touch electrodes, and cariogenicity testing in rats. Both systems identified the same food as the least cariogenic or acidogenic food and

The antifungal activity of sodium silicate on Fusarium sulphureum and its inhibitory effect on dry rot of potato tubers were investigated. Sodium silicate strongly inhibited spore germination and mycelial growth. Morphological changes in sodium silicate-treated hyphae such as mycelium sparsity and

From 1995 to 2002, a case-control study on food groups and risk of cancer of the oral cavity and pharynx was conducted in Montevideo, Uruguay. Two hundred thirty cases were frequency-matched to 460 controls on age, residence, and urban/rural status. The study was restricted to men. The relationship

China is the biggest sweet potato (Ipomoea batatas (L.) Lam) producer in the world and its total production is about 100 million tons per year. Surveys for diseases of sweet potato in storage were conducted from 2011 to 2013 in Hebei Province, China. The storage roots from cultivars such as Yizi 138

The aim of this in vitro study was to evaluate the marginal integrity of an alkasite restoration in comparison to that of a conventional composite resin restoration following intra-coronal bleaching with 30% hydrogen peroxide (HP) containing sweet potato extract (SPE) as an additive. Access

The nation's eating habits are undergoing major transformation, with a swing away from traditional meals to a huge increase in snack consumption, but very little is known of the nutritional and dental implications of this change. The research project reported here evaluated a range of snack foods in

The rate of salt release in-mouth from salted potato crisps was evaluated. It was hypothesised that a slow steady release of sodium would occur on chewing and hydration; to test this a crisp was chewed and held in the oral cavity without swallowing for 60 s. Sodium release was measured over the

During a survey of carrot (Daucus carota L.) cavity spot in Michigan in September 2010, carrot roots with typical cavity spot symptoms were collected from production fields in Fremont Co. The lesions were excised from infected roots, surface-disinfested with 0.62% NaClO for 3 min, rinsed in

Several different approaches are used to describe the role of protein compartments and residues in catalysis and to identify key residues suitable for the modification of the activity or selectivity of the desired enzyme. In our research, we applied a combination of molecular dynamics simulations
