1. Evidências de desregulação endócrina causada pela exposição aquática ao alumínio e ao manganês em Astyanax bimaculatus (Linnaeus, 1758) / Evidences of endocrine disruption caused by aquatic exposure to aluminum and manganese in Astyanax bimaculatus (Linnaeus, 1758)
Metals such as Aluminum (Al) and Manganese (Mn) are found in nature as well as in industrial effluents, and can be toxic to aquatic biota, with endocrine disrupting effects, e.g. for fish, which can affect the reproductive performance of a species. Rivers and tributaries of São Paulo State, even in theoretically preserved areas, have shown an increase in th

2. Fracionamento de cobre em proteínas do plasma, músculo e fígado de tilápia do Nilo
Copper fractionation in plasma, muscle and liver of Nile tilapia was performed after protein separation by 2D-PAGE. SR XRF analysis indicated the presence of copper in three protein spots of plasma, and in two protein spots of muscle and liver, respectively. Copper ions were found to be distributed mostly in proteins that had a molar mass of less than 54 kDa

3. Respostas fisiológicas de tambaqui a banhos terapêuticos com mebendazol.
O objetivo deste trabalho foi avaliar as respostas fisiológicas de tambaqui (Colossoma macropomum, Cuvier 1818) a banhos terapêuticos com mebendazol. Juvenis de tambaqui (n = 108, massa média de 37,80±0,24 g) foram submetidos a banhos terapêuticos de mebendazol a 0, 100, 300 e 600 mg L-1, com três repetições, em exposições de 30, 60 e 120 minutos.

4. Estudos das propriedades ópticas dos complexos európio tetraciclinas e suas aplicações na detecção de lipoproteínas / Studies of optical properties of complexes europium tetracycline and its applications in detection of lipoproteins
This work presents the optical properties of europium complexes - Tetracyclines (EuTcs) in the presence of LDL and oxidized LDL with potential applications in clinical analysis. Four elements were chosen from the Tetracyclines family: Tetracycline (Tc), Chlortetracycline (CTc), Metatetraciclina (MTc) and Oxytetracycline (OTc) to be part of complexes with eur

5. Alterações plasmáticas do cobre e do zinco em crianças submetidas a cirurgia cardíaca com circulação extracorpórea
The cardiac surgery, comprising extracorporeal circulation, is known to trigger oxidative stress due to the formation of reactive oxygen species and free radicals during the periods of ischemia and reperfusion. They are hazardous to the heart cell components and regarded as responsible for the myocardial stunned. These processes are intricately associated wi

6. Metabolic parameters and plasma ions of piavas (Leporinus obtusidens) exposed to different ammonia and dissolved oxygen levels / PARÂMETROS METABÓLICOS E ÍONS PLASMÁTICOS DE PIAVAS (Leporinus obtusidens) EXPOSTAS A DIFERENTES NÍVEIS DE OXIGÊNIO DISSOLVIDO E AMÔNIA
Piava juveniles (7-13 cm; 25-30 g) were exposed to different NH3 (mg L-1): 0.003 (control), 0.1, 0.3, 0.7, 1.4, and dissolved oxygen levels (mg L-1): 1.0, 2.0, 3.0, 4.0, and 6.0, for 4 days (96h). Na+, K+, Cl-, and NH4 + plasma levels were measured, as well as metabolics and enzyme activity in tissues (liver, kidney, gills, and muscle). The lethal concentrat

7. PROPRIEDADES MECÂNICAS E TRIBOLÓGICAS DE AÇO AUSTENÍTICO 304 SUBMETIDO À NITRETAÇÃO POR: IMPLANTAÇÃO IÔNICA E IMPLANTAÇÃO IÔNICA POR IMERSÃO EM PLASMA.
The aim of this work is to characterize the mechanical and tribological properties of AISI 304 austenitic stainless steel submitted to N+ ion implantation and Nitrogen plasma immersion ion implantation (PI3). The ion implantation conditions were to obtain a plateau distribution of N íons in atomic concentrations of up to 27. The PI3 nitretation were perform

8. DECOMPOSIÇÃO DE COQUE, RESÍDUO DE VÁCUO E PETRÓLEO EXTRAPESADO POR PIROIDRÓLISE PARA A DETERMINAÇÃO DE CLORO
In this work, a method for chlorine determination in petroleum coke, vacuum and atmospheric residues and heavy petroleum was developed. The pyrohydrolysis sample decomposition method was used, which consists of sample pyrolysis at about 1000 oC in presence of water vapor. The influence of the main parameters on the pyrohydrolysis reaction, such as temperatur

9. Classificação de água de coco processada e natural por meio de HCA, PCA e teores de íons metálicos determinados por ICP OES
Inductively Coupled Plasma Optical Emission Spectrometry was used to determine Ca, Mg, Mn, Fe, Zn and Cu in samples of processed and natural coconut water. The sample preparation consisted in a filtration step followed by a dilution. The analysis was made employing optimized instrumental parameters and the results were evaluated using methods of Pattern Reco

10. Determinação de ions metalicos em moluscos bivalves do manguezal da região petrolifera de São Francisco do Conde - Reconcavo Baiano / Determination of metallic ions in bivalve molluscs from the petroliferous region of São Francisco do Conde Mangrove - Reconcavo Baiano
The pollution of oceans, bays and estuaries as a result of industrial and domestic effluents that contain metallic ions is one of the most important factors that lead to the contamination of bivalve molluscs. These organisms are greatly affected by the bioaccumulation of inorganic species, even at low concentrations, reflecting the environmental contaminatio

11. Potassium-free and potassium-containing electrolytes affect plasma ions and acid-base status of endurance horses
Effects of potassium supplementation were evaluated in four studies in endurance horses during races and treadmill exercise. In the first and second studies a potassium-free experimental formula was compared to potassium rich commercial formulas. The first study showed that supplementation increased plasma [K+], and that the extra sodium in the potassium-fre

12. Protection of plasmid DNA by a Ginkgo biloba extract from the effects of stannous chloride and the action on the labeling of blood elements with technetium-99m
Ginkgo biloba extract (EGb) is a phytotherapeutic agent used for the treatment of ischemic and neurological disorders. Because the action of this important extract is not fully known, assays using different biological systems need to be performed. Red blood cells (RBC) are labeled with technetium-99m (Tc-99m) and used in nuclear medicine. The labeling depend
