Citrus aurantium L. essential oil exhibits anxiolytic-like activity mediated by 5-HT1A-receptors and reduces cholesterol after repeated oral treatment
(BMC Complementary and Alternative Medicine, 2013-02-23) [Artigo]
Background: The current treatments for anxiety disorders and depression have multiple adverse effects in addition to a delayed onset of action, which has prompted efforts to find new substances with potential activity in ...
Macrophage activity and histopathology of the lymphohematopoietic organs in male Wistar rats orally exposed to single or mixed pesticides
(Journal of Environmental Science and Health - Part B: Pesticides, Food Contaminants, and Agricultural Wastes, 2013-07-01) [Artigo]
The noxious effects of low or effective dose exposure to single or mixed pesticides on macrophage activity and the lymphohematopoietic organs were investigated. Male Wistar rats were orally exposed to dichlorvos, dicofol, ...
Previous contact with Strongyloides venezuelensis contributed to prevent insulitis in MLD-STZ diabetes
(Experimental Parasitology, 2013-06-01) [Artigo]
Epidemiological and experimental studies support the idea that helminth infections can induce a protective effect against the development of autoimmune and allergic diseases. In this study we characterized the immune ...
Diet-induced obesity impairs AKT signalling in the retina and causes retinal degeneration
(Cell Biochemistry and Function, 2013-01-01) [Artigo]
Retinopathy, a common complication of diabetes, is characterized by an unbalanced production of nitric oxide (NO), a process regulated by nitric oxide synthase (NOS). We hypothesized that retinopathy might stem from changes ...

(Histopathology, 1997-02-21) [Artigo]
Pulmonary paracoccidioidomycosis in immunized mice
(Mycopathologia, 1992-07-01) [Artigo]
Paracoccidioidomycosis was induced in immunized (IM) and non-immunized (NI) mice. The histopathology, the number of fungi in the lungs, the cellular (footpad test - FPT and macrophage inhibition factor assay - MIF) and ...
Frequent p53 mutations and occasional loss of chromosome 4 in invasive bladder carcinoma induced by N-butyl-N-(4-hydroxybutil)nitrosamine in B6D2F1 mice
(Molecular Carcinogenesis, 1998-03-16) [Artigo]
B6D2F1 mice (45/group) were treated with N-butyl-N-(4- hydroxybutyl)nitrosamine (BBN) or uracil as follows: Group 1 received 0.05% BBN in drinking water for the entire experiment, Group 2 received 5 mg of BBN by gastric ...
Comparison of uroplakin expression during urothelial carcinogenesis induced by N-butyl-N-(4-hydroxybutyl)nitrosamine in rats and mice
(Toxicologic Pathology, 1999-12-08) [Artigo]
The expression of uroplakins, the tissue-specific and differentiation- dependent membrane proteins of the urothelium, was analyzed immunohistochemically in N butyl-N-(4-hydroxybutyl)nitrosamine (BBN)-treated rats and mice ...
Emperipolesis in a Case of B-Cell Lymphoma: A Rare Phenomenon Outside of Rosai-Dorfman Disease
(Annals of Diagnostic Pathology, 2003-10-01) [Artigo]
We describe a case of a diffuse large B-cell lymphoma with extensive emperipolesis phenomenon. Light microscopy revealed numerous CD68-positive/S-100-negative histiocytes containing viable neoplastic hematopoietic cells ...
Fine needle aspiration biopsy of gastrointestinal stromal tumor presenting as an umbilical mass (Sister Mary Joseph's nodule)
(Annals of Diagnostic Pathology, 2006-04-01) [Artigo]
The Sister Mary Joseph (SMJ) nodule is a clinical sign of metastatic cancer involving the umbilicus. The vast majority of these instances represent adenocarcinomas arising from ovarian or colorectal primaries. We present ...
