Chitosan-based dressings loaded with neurotensin—an efficient strategy to impro...
Moura, Liane I. F.; Dias, Ana M. A.; Leal, Ermelindo C.; Carvalho, Lina; Sousa, Hermínio C. de; Carvalho, EugéniaOne important complication of diabetes mellitus is chronic, non-healing diabetic foot ulcers (DFUs). This study aims to develop and use dressings based on chitosan derivatives for the sustained delivery of neurotensin (NT), a neuropeptide that acts as an inflammatory modulator in wound healing. Three different derivatives, namely N-carboxymethyl chitosan, 5-methyl pyrrolidinone chitosan (MPC) and N-succinyl chi...
IL-6 and TNF-alpha polymorphisms in portuguese psoriatic patients
Ferreira, J.P.; Torres, T.; Carvalho, C.; Bettencourt, A.; Leal, B.; Vasconcelos, C.; Costa, P.P.; Selores, M.; Silva, B.M.Introduction: Cytokines regulate the growth, function and differentiation of cells and help to steer immune response and inflammation. In this study we focused our attention in two proinflammatory cytokines: IL-6 and TNFa. It is known that their overexpression is responsible for initiation, maintenance and recurrence of skin lesions in psoriatic patients. Therefore, it is important to investigate genetic biomar...
Apoe isoforms in patients with psoriasis
Ferreira, J.C.P.; Torres, T.; Carvalho, C.A.; Bettencourt, A.; Leal, B.; Vasconcelos, C.; Costa, P.P.; Selores, M.; Silva, B.M.Introduction: Psoriasis is a chronic inflammatory skin disease affecting 2–3% of the world population. Patients with psoriasis (Ps) have higher prevalence of lipid disorders when compared to unaffected individuals. These patients, especially those with severe and prolonged disease, have an increased morbidity and mortality from cardiovascular events. Apolipoprotein E (ApoE), a protein involved in lipid metaboli...
Epilepsy, hippocampal sclerosis and febrile seizures linked by common genetic v...
Kasperavičiute, D.; Catarino, C.B.; Matarin, M.; Leu, C.; Novy, J.; Tostevin, A.; Leal, B.; Hessel, E.V.S.; Hallmann, K.; Hildebrand, M.S.; Dahl, H-H.M.Epilepsy comprises several syndromes, amongst the most common being mesial temporal lobe epilepsy with hippocampal sclerosis. Seizures in mesial temporal lobe epilepsy with hippocampal sclerosis are typically drug-resistant, and mesial temporal lobe epilepsy with hippocampal sclerosis is frequently associated with important co-morbidities, mandating the search for better understanding and treatment. The cause o...
New syntheses of potential biologically active xanthones and benzoxanthones
Rocha, Djenisa H. A.; Leal, Stephanie B.; Seca, Ana M. L.; Pinto, Diana C. G. A.; Silva, Artur M. S.10º Encontro Nacional de Química Orgânica e 1º Simpósio Luso-Brasileiro de Química Orgânica, Lisboa, 4-6 Setembro de 2013. ; The synthesis of xanthones, adequately functionalized for a specific application, is a challenging task. In this presentation, will be disclosed our recent studies with this unique family of compounds, namely the one-pot photoinduced electrocyclisation of (E)-3-styrylflavones 1 and in si...
Exercise attenuates levodopa-induced dyskinesia in 6-hydroxydopamine-lesioned mice
Jr., A. S. Aguiar; Moreira, E. L. G.; Hoeller, A. A.; Oliveira, P. A.; Córdova, F. M.; Glaser, V.; Walz, R.; Cunha, R. A.; Leal, R. B.; Latini, A.l-DOPA alleviates the motor symptoms of Parkinson’s disease, but its long-term use is associated with undesirable dyskinesia. We now tested whether exercise can attenuate this l-DOPA-induced dyskinesia (LID). We tested the effects of exercise on LID in 6-hydroxydopamine hydrochloride-hemiparkinsonian mice. Animals were treated with l-DOPA/benserazide (25/12.5 mg/kg, i.p.) without and with possibility to exercis...
Comparative study of chronic TLE patients using structural and metabolic MRI me...
P.M. Goncalves Pereira; M. Forjaz Secca; A. Leal; P. Evangelista; C. Ribeiro; P. RosadoChemical-shift imaging (CSI) has been applied to the evaluation of patients with temporal lobe epilepsy (TLE), but few comparisons have been made between the data obtained from quantitative structural magnetic resonance imaging (MRI) and the accuracy of CSI to identify pathological changes within the hippocampus. Our goal was to determine the discriminative capability of CSI h...
Ocorrência de doença infundibular, sobremordida e ganchos em equinos de cavalar...
Lima,J.T.M; Andrade,B.S.C; Schwarzbach,S.V; De Marval,C.A; Leal,B.B; Faleiros,R.R; Alves,G.E.SAvaliou-se a ocorrência da doença infundibular (DI) e a associação entre sobremordida (SM) e ganchos dentários rostral e caudal da maxila e mandíbula. Utilizaram-se 88 equinos - 52 machos e 36 fêmeas -, entre três e 27 anos. Para os exames odontológicos, os animais foram contidos em brete e sedados com xilazina 10% a 0,5mg/kg IV e utilizaram-se abridor de boca, fotóforo elétrico e sonda odontológica de aço inox...
In vivo and in vitro anti-inflammatory and anti-nociceptive activities of lovas...
Gonçalves,D.O.; Calou,I.B.F.; Siqueira,R.P.; Lopes,A.A.; Leal,L.K.A.; Brito,G.A.C.; Tomé,A.R.; Viana,G.S.B.Statins are among the most prescribed drugs in recent clinical practice. They are also known for their pleiotropic actions, which are independent of their lipid-lowering properties. The effect of lovastatin was investigated against carrageenan-induced paw edema in male Wistar rats (200-250 g) and on leukocyte migration, as measured by carrageenan-induced peritonitis in male Swiss mice (20-25 g), which are model...
Antifungal activity of the naphthoquinone beta-lapachone against disseminated i...
Medeiros,C.S.; Pontes-Filho,N.T.; Camara,C.A.; Lima-Filho,J.V.; Oliveira,P.C.; Lemos,S.A.; Leal,A.F.G.; Brandão,J.O.C.; Neves,R.P.The in vivo antifungal activity of the naphthoquinone beta-lapachone against disseminated infection by Cryptococcus neoformans was investigated. Swiss mice were immunosuppressed daily with dexamethasone (0.5 mg per mouse) intraperitoneally for 3 days, the procedure was repeated 4 days later, and the animals were then challenged intravenously with C. neoformans (10(6) CFU/mL) 1 week later. Seven days after infec...
