The Impact of Long-Term Intake of Phenolic Compounds-Rich Grape Pomace on Rat Gut Microbiota.

Unlabelled: The aim of this work is to evaluate the impact on the rat microbiota of long-term feeding with phenolic compounds (PC) rich grape pomace extracts. Thirty, 2-mo-old rats, were divided into 5 groups. Four groups were treated with different concentrations of PC (2.

Caries risk management: effect on caries incidence in a sample of Lebanese preschool children.

Objectives: This clinical prospective study describes how caries preventive measures applied according to caries risk affect new caries incidence in a group of preschoolers, as compared to a group where standardized caries prevention is applied, regardless of risk.

Method And Materials: Healthy children, aged four years or less, recruited at the Faculté de Médecine Dentaire, Université Saint-Joseph, Beirut, Lebanon were assigned, after parental consent, to an experimental or a control group. Caries risk was determined based on a parental questionnaire, salivary levels of Steptococcus mutans (Sm) and Lactobacillus (Lb), salivary buffer capacity, plaque levels and carious lesions prevalence, then subjects were classified into four caries risk categories.

Differentiation between Aspergillus flavus and Aspergillus parasiticus from pure culture and aflatoxin-contaminated grapes using PCR-RFLP analysis of aflR-aflJ intergenic spacer.

Aflatoxins (AFs) represent the most important single mycotoxin-related food safety problem in developed and developing countries as they have adverse effects on human and animal health. They are produced mainly by Aspergillus flavus and A. parasiticus.

[Long-term clinical evaluation of 2 dental materials used for the preparation of esthetic inlays].

Thirty-six inlays, equally divided between a vitro ceramic and a composite resin, were bonded in pair, on the same type of teeth in fifteen patients. They were followed for a mean period of 75 months. The results showed that both materials were clinically acceptable for restoring posterior teeth, even though ceramic yielded significantly better results concerning colour match and surface roughness.
