1. Heavy Metals and 2,4-Dinitrophenol Impact on Some Physiological and Biochemical Parameters in Capsicum Species
Abstract The accumulation of heavy metals and of pesticides in the soil have a negative impact on Capsicum chinense var. Aji Mochero and Capsicum baccatum var. pendulum Bishop's Crown species, the present work highlighting the exerted influence on the superoxid-dismutase activity, catalase and peroxidase - as enzymes implied in the removal of H2O2, of O2- ra

2. Assessment of Metabolism of the Eastern Oyster and Eastern Elliptio Using NMR Spectroscopy
Metabolites are known to characterize the functional responses of a cell. Therefore, a quantitative measurement of metabolite profiles can provide insight into the underlying effect of genetic or environmental actions on cell metabolism. It follows then that the study of the metabolite profiles of bivalve mollusks, such as oysters, can be particularly worthw

3. Fluvoxamine alters the activity of energy metabolism enzymes in the brain
Objective: Several studies support the hypothesis that metabolism impairment is involved in the pathophysiology of depression and that some antidepressants act by modulating brain energy metabolism. Thus, we evaluated the activity of Krebs cycle enzymes, the mitochondrial respiratory chain, and creatine kinase in the brain of rats subjected to prolonged adm

4. ProspecÃÃo de proteÃnas envolvidas no amadurecimento pÃs-colheita da graviola (Annona muricata L.) / Prospecting for proteins involved in post-harvest ripening of soursop (Annona muricata L.)
The soursop (Annona muricata L.) fruit is widely used in food, because it provides vitamins, carbohydrates, proteins, lipids and other molecules for human nutrition. In recent years, soursop (exotic tropical fruit) has had a prominent position in the Brazilian economy, especially for northeastern states such as, Ceara, Alagoas, Bahia and Pernambuco. The high

5. Surface-expressed enolases of Plasmodium and other pathogens
Enolase is the eighth enzyme in the glycolytic pathway, a reaction that generates ATP from phosphoenol pyruvate in cytosolic compartments. Enolase is essential, especially for organisms devoid of the Krebs cycle that depend solely on glycolysis for energy. Interestingly, enolase appears to serve a separate function in some organisms, in that it is also expor

6. A new approach for potential drug target discovery through in silico metabolic pathway analysis using Trypanosoma cruzi genome information
The current drug options for the treatment of chronic Chagas disease have not been sufficient and high hopes have been placed on the use of genomic data from the human parasite Trypanosoma cruzi to identify new drug targets and develop appropriate treatments for both acute and chronic Chagas disease. However, the lack of a complete assembly of the genomic se

7. Obesity and insulin resistance: molecular, biochemical and ultra-structural adaptations. / Obesidade e resistência à ação da insulina: alterações moleculares, bioquímicas e estruturais.
The possible causes of increased mortality and morbidity associated with obesity have been focused by many studies that attempt to understand the metabolic syndrome, characterized by various metabolic disorders such as insulin resistance, hypertension and dyslipidemia. Thus, the aim of this study was to verify the possible mechanisms responsible for developi

8. Identificação proteômica, expressão heteróloga, citolocalização, estudos de regulação transcricional e traducional da Aconitase Mitocondrial de Paracoccidioides brasiliensis / Identification,characterization and regulation studies of the mitochondrial Aconitase of Paracoccidioides brasiliensis
Paracoccidioides brasiliensis is a thermal-dimorphic fungus, the causative agent of Paracoccidioidomycosis (PCM), an important endemic mycosis in Latin America. A protein species preferentially expressed in yeast cells with a molecular mass of 80kDa and isoeletric point (pI) of 7.79 was isolated from the proteome of P. brasiliensis and characterized as an ac

9. Effects of ZmDof1 and OsDof25 transcriptional factors superexpression on nitrogen usage efficiency in Arabidopsis. / Efeito da superexpressão dos fatores de transcrição ZmDof1 e OsDof25 sobre a eficiência de uso de nitrogênio em Arabidopsis.
To improve nitrogen usage efficiency in plants the rice transcriptional factor OsDof25 was identified and cloned, whose probably orthologe is the maize ZmDof1, already identified and partially characterized. The ZmDof1 was also cloned for comparative analysis with OsDof25, in order to confirm this last one as ZmDof1 orthologe in rice. The constructions for A

10. CARACTERIZAÇÃO DA ATIVIDADE PRÓ-OXIDANTE DE DIFERENTES AGENTES E ESTUDO DO POTENCIAL ANTIOXIDANTE DE INTERMEDIÁRIOS DO CICLO DE KREBS SOBRE ALTERAÇÕES OXIDATIVAS INDUZIDAS IN VITRO / EFFECT OF KREBS CYCLE INTERMEDIATES ON OXIDATIVE CHANGES INDUCED BY DIFFERENT OXIDANT AGENTS
Dados prévios da literatura têm mostrado que alguns intermediários do ciclo de Krebs podem agir como antioxidantes em diversos modelos, tanto in vitro, quanto in vivo. Porém, o(s) mecanismo(s) através dos qual(is) esses intermediários exercem suas atividades antioxidantes não são completamente entendidas. Considerando a escassez de dados na literatur

12. EFEITO DE INTERMEDIÁRIOS DO CICLO DE KREBS SOBRE ALTERAÇÕES OXIDATIVAS INDUZIDAS POR DIFERENTES AGENTES OXIDANTES / EFFECT OF KREBS CYCLE INTERMEDIATES ON OXIDATIVE CHANGES INDUCED BY DIFFERENT OXIDANT AGENTS
Recent data from the literature have suggested that some Krebs cycle intermediates could act as potent antioxidant agents, both in vitro and in vivo, against a variety of pro-oxidant agents. However, the mechanism(s) involved in the antioxidant effect of Krebs cycle intermediates are not fully understood. Additionally, there are scarce data in the literature
