A coalgebraic perspective on logical interpretations
Martins, M. A.; Madeira, A.; Barbosa, L. S.In Computer Science stepwise refinement of algebraic specifications is a well-known formal methodology for rigorous program development. This paper illustrates how techniques from Algebraic Logic, in particular that of interpretation, understood as a multifunction that preserves and reflects logical consequence, capture a number of relevant transformations in the context of software design, reuse, and adaptatio...
Physico-chemical property prediction and environmental fate modelling of N-acyl...
Schröder, B.; Martins, M.A.R.; Pinho, Simão; Coutinho, J.A.P.(Subcooled) vapour pressures, aqueous solubilities, Henry constants, log KOW and log KOC partition constants have been estimated for a set of N-acyl-chalcogenourea derivatives using several prediction methods (COSMO-RS in its COSMOtherm implementation, SPARC as well as EPA’s EPIsuite). The data are discussed in terms of substituent effects: how do subtle changes in the chemical composition influence basic physi...
Partial molar volumes of amino acids in aqueous solutions containing ammonium ...
Martins, M.A.; Mota, P.C.; Ferreira, Olga; Hnědkovský, L.; Pinho, Simão; Cibulka, I.Because proteins are large complex molecules direct study of protein-electrolyte interactions is difficult. It is therefore useful investigate the interaction of model coumpounds such amino acids, peptides has strongly attracting the attention researchers to describe their physico-chemical properties.
Inactivation of capsaicin-sensitive nerves reduces pulmonary remodeling in guin...
Prado,C.M.; da Rocha,G.Z.; Leick-Maldonado,E.A.; Starling,C.M.; Capelozzi,V.L.; Martins,M.A.; Tibério,I.F.L.C.Pulmonary remodeling is an important feature of asthma physiopathology that can contribute to irreversible changes in lung function. Although neurokinins influence lung inflammation, their exact role in the extracellular matrix (ECM) remodeling remains to be determined. Our objective was to investigate whether inactivation of capsaicin-sensitive nerves modulates pulmonary ECM remodeling in animals with chronic ...
Short-term exposure of mice to cigarette smoke and/or residual oil fly ash prod...
Biselli,P.J.C.; Lopes,F.D.T.Q.S.; Moriya,H.T.; Rivero,D.H.R.F.; Toledo,A.C.; Saldiva,P.H.N.; Mauad,T.; Martins,M.A.Chronic obstructive pulmonary disease (COPD) is associated with inflammatory cell reactions, tissue destruction and lung remodeling. Many signaling pathways for these phenomena are still to be identified. We developed a mouse model of COPD to evaluate some pathophysiological mechanisms acting during the initial stage of the disease. Forty-seven 6- to 8-week-old female C57/BL6 mice (approximately 22 g) were expo...
Antipyretic and antioxidant activities of 5-trifluoromethyl-4,5-dihydro-1H-pyra...
Pasin,J.S.M.; Ferreira,A.P.O.; Saraiva,A.L.L.; Ratzlaff,V.; Andrighetto,R.; Machado,P.; Marchesan,S.; Zanette,R.A.; Bonacorso,H.G.; Zanatta,N.The objective of this study was to determine the effect of eight 5-hydroxy-5-trifluoromethyl-4,5-dihydro-1H-1-carboxyamidepyrazoles (TFDPs) on rat body temperature and baker’s yeast-induced fever. TFDPs or vehicle (5% Tween 80 in 0.9% NaCl, 5 mL/kg) were injected subcutaneously and rectal temperature was measured as a function of time in 28-day-old male Wistar rats (N = 5-12 per group). Antipyretic activi...

Effects of exercise training on atrophy gene expression in skeletal muscle of m...
Durigan,J.L.Q.; Peviani,S.M.; Russo,T.L.; Silva,A.C.D.; Vieira,R.P.; Martins,M.A.; Carvalho,C.R.F.; Salvini,T.F.We evaluated the effects of chronic allergic airway inflammation and of treadmill training (12 weeks) of low and moderate intensity on muscle fiber cross-sectional area and mRNA levels of atrogin-1 and MuRF1 in the mouse tibialis anterior muscle. Six 4-month-old male BALB/c mice (28.5 ± 0.8 g) per group were examined: 1) control, non-sensitized and non-trained (C); 2) ovalbumin sensitized (OA, 20 µg per mouse);...
13CO2 recovery fraction in expired air of septic patients under mechanical vent...
Martins,M.A.; Coletto,F.A.; Martins-Filho,O.A.; Marchini,J.S.; Basile-Filho,A.The continuous intravenous administration of isotopic bicarbonate (NaH13CO2) has been used for the determination of the retention of the 13CO2 fraction or the 13CO2 recovered in expired air. This determination is important for the calculation of substrate oxidation. The aim of the present study was to evaluate, in critically ill patients with sepsis under mechanical ventilation, the 13CO2 recovery fraction in e...
A pyrazolyl-thiazole derivative causes antinociception in mice
Prokopp,C.R.; Rubin,M.A.; Sauzem,P.D.; de Souza,A.H.; Berlese,D.B.; Lourega,R.V.; Muniz,M.N.; Bonacorso,H.G.; Zanatta,N.; Martins,M.A.P.; Mello,C.F.The present study investigates the antinociceptive effect of the pyrazolyl-thiazole derivative 2-(5-trichloromethyl-5-hydroxy-3-phenyl-4,5-dihydro-1 H-pyrazol-1-yl)-4-(4-bromophenyl)-5-methylthiazole (B50) in mice. Male albino Swiss mice (30-40 g) were used in the acetic acid-induced abdominal writhes and tail-immersion tests. B50 caused dose-dependent antinociception (8, 23 and 80 µmol/kg, sc) in the acetic ac...
