Many elasmobranch species are undergoing population declines on a global scale; however, implementation of effective conservation and management strategies is hindered, to a large extent, by a lack of sufficient data on diet, life history and behaviour. Thiswork is a primer of how stable isotope analysis can be used as a cost-effective, relatively simple(More)
Candida species are a normal commensal present in a large percentage of healthy individuals. Denture wearers are predisposed to the development of candidosis and to the presence of Candida spp. The presence of the yeast, even in healthy subjects, should be considered more carefully. We investigated the prevalence of Candida spp. in 112 denture wearers and(More)
The aim of this study was to assess the adhesion ability by Candida spp. obtained from denture wearer patients with and without denture stomatitis and the possible reduction in adhesion after exposure to fluconazole. Nine C. tropicalis, five C. glabrata and two C. parapsilosis obtained from the oral cavity of patients with denture stomatitis and 11 C.(More)
OBJECTIVE The aim of this study was to assess the contribution and the correlation between the virulence factors of Candida albicans in denture stomatitis. STUDY DESIGN Thirty C. albicans strains obtained from the oral cavity of patients with denture stomatitis and 30 C. albicans obtained from the oral cavity of denture wearers with normal palatal mucosa(More)
Sixty isolates of Candida albicans, 30 obtained from the oral cavity of denture wearers presenting signs of candidosis and 30 obtained from the oral cavity of denture wearers with normal palatal mucosa were assayed for phospholipase and proteinase production, as well as for adherence to buccal epithelial cells. Likewise, susceptibility of the isolates to(More)
The present work is focussed on the principles of photodynamic therapy (PDT), emphasizing the photochemical mechanisms of reactive oxygen species formation and the consequent biochemical processes generated by the action of reactive oxygen species on various biological macromolecules and organelles. This paper also presents some of the most used(More)
Photodynamic therapy (PDT) is a minimally invasive approach, in which a photosensitizer compound is activated by exposure to light. The activation of the sensitizer drug results in several chemical reactions, such as the production of reactive oxygen species and other reactive molecules, which presence in the biological site leads to the damage of target(More)
Infections caused by Candida yeasts are common in elderly individuals. Seventy-five isolates of Candida spp. were obtained from saliva samples of 136 institutionalized elderly individuals resident in six retirement homes of Belo Horizonte, Brazil. Forty-seven isolates (62.66%) were identified as Candida albicans, 15 (20%) as C. tropicalis, 7 (9.33%) as C.(More)
Photodynamic therapy (PDT) is a minimally invasive approach, in which a photosensitiser compound is activated by exposure to visible light. The activation of the sensitiser drug results in several chemical reactions, such as the production of oxygen reactive species and other reactive molecules, whose presence in the biological site leads to the damage of(More)
