Papilomavírus humano (HPV) em lesões benignas e malignas de mucosa oral pelos métodos de imuno-histoquímica e hibridização in situ
(Revista de Ciencias Farmaceuticas, 2002-12-01) [Artigo]
Fifteen oral biopsies with histopathological diagnosis of oral papilloma (n=7) and invasive squamous cell carcinoma (n=8) have been investigated for the presence of human papillomavirus (HPV) by immunohistochemistry (IHC) ...
Temporal response pattern of biochemical analytes in experimental diabetes
(Applied Biochemistry and Biotechnology, 2003-10-01) [Artigo]
The activities of the enzymes aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LD), creatine kinase (CK), amylase (AMS) and angiotensin converting enzyme ...
Effects of subtypes of adrenergic and angiotensinergic antagonists on the water and sodium intake induced by adrenaline injected into the paraventricular nucleus
(Brain Research, 2003-12-24) [Artigo]
The present experiments were conducted to investigate die role of the alpha(1A)-, alpha(1B)-, beta(1)-, beta(2)-adrenoceptors, and the effects of losartan and CGP42112A (selective ligands of the AT(1) and AT(2) angiotensin ...

Paracoccidioidomycosis manifesting as oral lesions: clinical, cytological and serological investigation
(Journal of Oral Pathology & Medicine, 1994-02-01) [Artigo]
Paracoccidioidomycosis (South American blastomycosis) is a systemic mycosis which can be associated with oral lesions. This study on a group of 14 patients showed oral lesions mainly on the gingival or alveolar mucosa, ...
In vitro and in vivo investigation of the biological and mechanical behaviour of resin-modified glass-ionomer cement containing chlorhexidine
(Journal of Dentistry, 2013-02-01) [Artigo]
Objectives: To evaluate: (1) the in vitro antibacterial, cytotoxic and mechanical properties of a resin-modified glass ionomer cement (RMGIC) containing different concentrations of chlorhexidine (CHX) and (2) the in vivo ...

(Brazilian Journal of Oral Sciences, 2014-04-01) [Artigo]
AIM: To assess the combined use of tetracycline (TTC) and ethylenediaminetetraacetic acid (EDTA) on clot formation, considering that EDTA may neutralize TTC acidity. METHODS: Planed human tooth roots were treated with ...
Endodontic Chelators Induce Nitric Oxide Expression by Murine-cultured Macrophages
(Journal of Endodontics, 2009-06-01) [Artigo]
Introduction: Endodontic chelators may extrude to apical tissues during instrumentation activating cellular events on periapical tissues. This study assessed in vitro the expression of nitric oxide (NO) concentrations by ...
The influence of short-term diabetes mellitus and insulin therapy on alveolar bone loss in rats
(Journal of Periodontal Research, 2004-06-01) [Artigo]
Background: It is well known that the multiple direct and indirect consequences of hyperglycemia in diabetic individuals have been linked to a number of abnormal host effector mechanisms that could lead to an increased ...
Photodynamic inactivation of planktonic cultures and biofilms of Candida albicans mediated by aluminum-chloride-phthalocyanine entrapped in nanoemulsions
(Photochemistry and Photobiology, 2013-01-01) [Artigo]
New drug delivery systems, such as nanoemulsions (NE), have been developed to allow the use of hydrophobic drugs on the antimicrobial photodynamic therapy. This study evaluated the photodynamic potential of aluminum-chloride- ...
