1. Radioprotective Effect of Nigella Sativa Oil on Heart Tissues of Rats Exposed to Irradition
Abstract Background Various studies are ongoing related to the radioprotective agents. Herbal preparations are currently becoming popular because of their beneficial effects with fewer side effects compared to the synthetic/semi-synthetic medicines, and Nigella sativa oil (NSO) is only one of them. Objective To investigate NSO for its antioxidant effects

2. EVALUATION OF PSORIASIS TREATMENT WITH ESOMEPRAZOLE - A PILOT STUDY
RESUMO CONTEXTO: A psoríase é uma doença inflamatória da pele que afeta 1%-3% das populações caucasianas e pode ser persistente, desfigurante e estigmatizante. Inibidores da bomba de prótons (IBP) são potentes bloqueadores da secreção de ácido no estômago. Eles são considerados como os agentes de escolha para o tratamento de doenças ácido-p�

3. Effects of Aliskiren, an RAAS inhibitor, on a carrageenan-induced pleurisy model of rats
Abstract Our aim is to investigate the potentially preventive effects of Aliskiren in a carrageenan-induced lung pleurisy model and to compare the standard anti-inflammatory agents, indomethacin and dexamethasone. The pleurisy model was induced through the injection of carrageenan (0.2 ml-%2) into the pleural cavity. After the experiment, serum and lung tiss

4. First evaluation of semidirect recycling methods for the reclamation of cemented carbides based on a literature survey
ABSTRACT At the moment the industrially applied techniques for cemented carbide reclamation feature several deficiencies. Depending on the process route, obstacles consist in high energy and chemical consumption (indirect recycling methods) or a deterioration of the recycled product in comparison with the primary material (direct recycling approach). Therefo

6. Differential expression on mitochondrial tryparedoxin peroxidase (mTcTXNPx) in Trypanosoma cruzi after ferrocenyl diamine hydrochlorides treatments
Abstract Resistance to benznidazole in certain strains of Trypanosoma cruzi may be caused by the increased production of enzymes that act on the oxidative metabolism, such as mitochondrial tryparedoxin peroxidase which catalyses the reduction of peroxides. This work presents cytotoxicity assays performed with ferrocenyl diamine hydrochlorides in six differen

7. An oxidant and organic solvent tolerant alkaline lipase by P. aeruginosa mutant: downstream processing and biochemical characterization
An extracellular alkaline lipase from Pseudomonas aeruginosa mutant has been purified to homogeneity using acetone precipitation followed by anion exchange and gel filtration chromatography and resulted in 27-fold purification with 19.6% final recovery. SDS-PAGE study suggested that the purified lipase has an apparent molecular mass of 67 kDa. The optimum te

8. Pharmacology and toxicology of diphenyl diselenide in several biological models
The pharmacology of synthetic organoselenium compounds indicates that they can be used as antioxidants, enzyme inhibitors, neuroprotectors, anti-tumor and anti-infectious agents, and immunomodulators. In this review, we focus on the effects of diphenyl diselenide (DPDS) in various biological model organisms. DPDS possesses antioxidant activity, confirmed in

9. Adaptação de equipamento de geração de gases oxidantes para aplicação na desinfecção de água / Adaptation of generator oxidant gases equipament to aplication in water disinfection
Human consumption of water outside of the microbiological standards for drinking constitutes a health and disease risk factor. Through the process of infiltration in the soil, groundwater may be contaminated by the waste generated by human activity and deposited in the soil, waterways or air. The consumption of water in natura, captured in a spring, may lead

10. AVALIAÇÃO TOXICOLÓGICA DE ORGANOCALCOGÊNIOS EM ERITRÓCITOS HUMANOS / TOXICOLOGICAL EVALUATION OF ORGANOCHALCOGENS IN HUMAN ERYTHROCYTES
The interest in organochalcogen chemistry, biochemistry and pharmacology has increased in the last two decades mainly due to the fact that a variety of organochalcogen compounds possess biological activity and due the use of these compounds in industrial applications. However, literature data showed that these compounds present pro-oxidant properties, causin

12. EFFECT OF DIPHENYL DISELENIDE ON TOXICITY INDUCED BY MERCURIC CHLORIDE IN MICE / EFEITO DO DISSELENETO DE DIFENILA SOBRE A TOXICIDADE INDUZIDA POR CLORETO DE MERCÚRIO EM CAMUNDONGOS
Mercury is a metal without physiological functions in human body and is toxic to human beings. This metal has many applications in industry and, therefore it is very important in occupational and environmental exposure. The toxicity of mercury depends on the form of the metal and can affect several organs, such as brain, kidney and liver. In addition, mercur
