1. Meta-topolin: an alternative for the prevention of oxidative stress in sugarcane micropropagation
RESUMO A influência de duas citocininas aromáticas (CKs), 6-benzilaminopurina (BAP) e meta-topolina (mT) na propagação in vitro e no metabolismo redox da cana-de-açúcar (Saccharum spp., variedade RB98710) foi investigada. As plantas foram cultivadas em meio Murashige e Skoog (MS) suplementado com mT (5 µmol.L-1) ou BAP (5 ou 6,66 µmol.L-1) por 40 dia

2. Expression of genes related to soil flooding tolerance in soybeans
ABSTRACT. The flooded environment brings about injuries to soybeans that vary depending on the adaptation ability of the genotype. Oxygen deprivation promotes the induction of the expression of genes related to glycolysis and fermentation pathways to maintain energy metabolism and, in addition to reducing-power consuming processes, act in the formation of ad

3. Protein-protein interactions of the nicotinamide/nicotinate mononucleotide adenylyltransferase of Leishmania braziliensis
BACKGROUND Nicotinamide adenine dinucleotide (NAD) plays a central role in energy metabolism and integrates cellular metabolism with signalling and gene expression. NAD biosynthesis depends on the enzyme nicotinamide/nicotinate mononucleotide adenylyltransferase (NMNAT; EC: 2.7.7.1/18), in which converge the de novo and salvage pathways. OBJECTIVE The pu

5. Hepatoprotective effect of Alhagi sparsifolia against Alcoholic Liver injury in mice
Overconsumption of alcohol leads to alcoholic liver disease (ALD). Natural compounds have been investigated previously for their hepatoprotective activities against liver injury. This study investigated the protective effect of Alhagi sparsifolia on ALD. Alcohol was administered to mice for three consecutive days; either alone or in combination with Alhagi s

6. Increased thiol levels in antimony-resistant Leishmania infantum isolated from treatment-refractory visceral leishmaniasis in Brazil
BACKGROUND Treatment-refractory visceral leishmaniasis (VL) has become an important problem in many countries. OBJECTIVES We evaluated the antimony-resistance mechanisms of Leishmania infantum isolated from VL patients refractory or responsive to treatment with pentavalent antimony. METHODS Strains isolated from antimony-refractory patients (in vitro anti

7. Advances in enzyme bioelectrochemistry
ABSTRACT Bioelectrochemistry can be defined as a branch of Chemical Science concerned with electron-proton transfer and transport involving biomolecules, as well as electrode reactions of redox enzymes. The bioelectrochemical reactions and system have direct impact in biotechnological development, in medical devices designing, in the behavior of DNA-protein

8. Thiol/disulfide status regulates the activity of thiol-containing kinases related to energy homeostasis in rat kidney
ABSTRACT Considering that thiol-containing enzymes like kinases are critical for several metabolic pathways and energy homeostasis, we investigated the effects of cystine dimethyl ester and/or cysteamine administration on kinases crucial for energy metabolism in the kidney of Wistar rats. Animals were injected twice a day with 1.6 µmol/g body weight cystine

9. Aqueous extract of Baccharis trimera improves redox status and decreases the severity of alcoholic hepatotoxicity
ABSTRACT The metabolism of ethanol occurs mainly in the liver, promoting increase of reactive oxygen species and nitrogen, leading to redox imbalance. Therefore, antioxidants can be seen as an alternative to reestablish the oxidizing/reducing equilibrium. The aim of this study was to evaluate the antioxidant and hepatoprotective effect of aqueous extract of

10. Nicotinamide mononucleotide adenylyltransferase of Trypanosoma cruzi (TcNMNAT): a cytosol protein target for serine kinases
Nicotinamide/nicotinate adenine dinucleotide (NAD+/NaAD) performs essential functions in cell metabolism and energy production due to its redox properties. The nicotinamide/nicotinate mononucleotide adenylyltransferase (NMNAT, EC 2.7.7.1/18) enzyme catalyses the key step in the biosynthesis of NAD+. Previously, the enzyme NMNAT was identified in Trypanosoma

11. In silico molecular modeling and docking studies on the leishmanial tryparedoxin peroxidase
Leishmaniasis is one of the most common form of neglected parasitic disease that affects about 350 million people worldwide. Leishmanias have a trypanothione mediated hydroperoxide metabolism to eliminate endogenous or exogenous oxidative agents. Both of 2-Cys peroxiredoxin (Prx) and glutathione peroxidase type tryparedoxin peroxidase (Px) are the terminal e

12. Influência da restrição calórica no metabolismo bioenergético e estado redox de Saccharomyces cerevisiaee Kluyveromyces lactis / Influence of caloric restriction on energy metabolism and redox state of Saccharomyces cerevisiaee Kluyveromyces lactis
Aging involves a progressive decline in metabolic efficiency of biological systems over time. Although it cannot be avoided, aging phenotypes are delayed in organisms undergoing caloric restriction, a dietary regimen consisting of a reduced availability of calories. The yeast Saccharomyces cerevisiae has proved to be an important model organism for studying
