Acute blockade of endogenous melatonin by Luzindole, with or without peripheral...
Matos,R.S.; Oriá,R.B.; Bruin,P.F.C.; Pinto,D.V.; Viana,A.F.S.C.; Santos,F.A.; Duarte,A.S.G.; Bruin,V.M.S.This study investigated the acute blockade of endogenous melatonin (MLT) using Luzindole with or without systemic lipopolysaccharide (LPS) challenge and evaluated changes in inflammatory and oxidative stress markers in the mouse jejunum. Luzindole is an MT1/MT2 MLT receptor antagonist. Both receptors occur in the small intestine. Swiss mice were treated with either saline (0.35 mg/kg, ip), Luzindole (0.35 mg/kg...
A Brazilian regional basic diet-induced chronic malnutrition drives liver infla...
Santos,M.J.S.; Canuto,K.M.; de Aquino,C.C.; Martins,C.S.; Brito,G.A.C.; Pessoa,T.M.R.P.; Bertolini,L.R.; de Sá Carneiro,I.; Pinto,D.V.Malnutrition is still considered endemic in many developing countries. Malnutrition-enteric infections may cause lasting deleterious effects on lipid metabolism, especially in children living in poor settings. The regional basic diet (RBD), produced to mimic the Brazilian northeastern dietary characteristics (rich in carbohydrate and low in protein) has been used in experimental malnutrition models, but few stu...
Alanyl-glutamine attenuates 5-fluorouracil-induced intestinal mucositis in apol...
Araújo,C.V.; Lazzarotto,C.R.; Aquino,C.C.; Figueiredo,I.L.; Costa,T.B.; de Oliveira Alves,L.A.; Ribeiro,R.A.; Bertolini,L.R.; Lima,A.A.M.; Brito,G.A.C.Apolipoprotein E (APOE=gene, apoE=protein) is a known factor regulating the inflammatory response that may have regenerative effects during tissue recovery from injury. We investigated whether apoE deficiency reduces the healing effect of alanyl-glutamine (Ala-Gln) treatment, a recognized gut-trophic nutrient, during tissue recovery after 5-FU-induced intestinal mucositis. APOE-knockout (APOE-/-) and wild-type ...
ApoE polymorphisms and diarrheal outcomes in Brazilian shanty town children
Oriá,R.B.; Patrick,P.D.; Oriá,M.O.B.; Lorntz,B.; Thompson,M.R.; Azevedo,O.G.R.; Lobo,R.N.B.; Pinkerton,R.F.; Guerrant,R.L.; Lima,A.A.M.A series of studies have shown that the heavy burdens of diarrheal diseases in the first 2 formative years of life in children living in urban shanty towns have negative effects on physical and cognitive development lasting into later childhood. We have shown that APOE4 is relatively common in shanty town children living in Brazil (13.4%) and suggest that APOE4 has a protective role in cognitive development as ...
Motor behavioral abnormalities and histopathological findings of Wistar rats in...
Câmara,C.C.; Oriá,R.B.; Felismino,T.C.; Silva,A.P. da; Silva,M.A.M. da; Alcântara,J.V.A.; Costa,S.B.C.; Vicente,A.C.P.; Teixeira-Santos,T.J.The objective of the present study was to describe motor behavioral changes in association with histopathological and hematological findings in Wistar rats inoculated intravenously with human T-cell lymphotropic virus type 1 (HTLV-1)-infected MT2 cells. Twenty-five 4-month-old male rats were inoculated with HTLV-1-infected MT2 cells and 13 control rats were inoculated with normal human lymphocytes. The behavior...
Comparison of etoricoxib and indomethacin for the treatment of experimental per...
Azoubel,M.C.F.; Menezes,A.M.A.; Bezerra,D.; Oriá,R.B.; Ribeiro,R.A.; Brito,G.A.C.We investigated the effect of etoricoxib, a selective cyclooxygenase-2 inhibitor, and indomethacin, a non-selective cyclooxygenase inhibitor, on experimental periodontitis, and compared their gastrointestinal side effects. A ligature was placed around the second upper left molars of female Wistar rats (160 to 200 g). Animals (6 per group) were treated daily with oral doses of 3 or 9 mg/kg etoricoxib, 5 mg/kg in...
