Strawberry polyphenols have been extensively studied over the last two decades for their beneficial properties. Recently, their possible use in ameliorating skin conditions has also been proposed; however, their role in preventing UVA-induced damage in cosmetic formulation has not yet been investigated. Skin is constantly exposed to several environmental stressors, such as UVA radiation, that i...

ABSTRACT Ulocladium atrum (strain 385) consistently reduced Botrytis cinerea sporulation on necrotic fragments of strawberry leaves. On these tissues, two strains of U. atrum (isolates 18558 and 18559) showed lower antagonistic activities than the reference strain 385. Colonization of strawberry leaflets by the three U. atrum strains appeared similar in the absence of B. cinerea, whether quanti...

In this study, we developed a procedure to produce gingivitis in rats by inoculation of Porphyromonas gingivalis and studied the contribution of the bacterial cysteine proteinases, Arg-gingipain (Rgp) and Lys-gingipain (Kgp), to the pathology in the gingiva. To adhere the bacterium to periodontal tissues, a cotton thread was inserted between the first and second molar of right maxillary sites o...

This three-month clinical trial was designed to compare the effect of an electric and a manual toothbrush on reducing primarily gingivitis and secondarily, plaque, in a cohort of 70 healthy adults. After baseline evaluation of gingivitis, soft tissue trauma, and plaque, patients were randomly assigned to one of the two experimental groups, shown an instructional tooth brushing videotape, and ha...
