1. Trypanosoma evansi is alike to Trypanosoma brucei brucei in the subcellular localisation of glycolytic enzymes
Trypanosoma evansi, which causes surra, is descended from Trypanosoma brucei brucei, which causes nagana. Although both parasites are presumed to be metabolically similar, insufficient knowledge of T. evansiprecludes a full comparison. Herein, we provide the first report on the subcellular localisation of the glycolytic enzymes in T. evansi, which is a alike

2. Yeast HXK2 gene reverts glucose regulation mutation of penicillin biosynthesis in P. chrysogenum
The mutant Penicillium chrysogenum strain dogR5, derived from strain AS-P-78, does not respond to glucose regulation of penicillin biosynthesis and β-galactosidase, and is partially deficient in D-glucose phosphorilating activity. We have transformed strain dogR5 with the (hexokinase) hxk2 gene from Saccharomyces cerevisiae. Transformants recovered glucose

3. O fator de transcrição AtbZIP63 como integrador de sinais energéticos e estresses biótico/abiótico / The transcription factor AtbZIP63 as a integrator of energetic signals and biotic/abiotic stresses
A manutenção do balanço energético em plantas é de crucial importância para a otimização de seu crescimento e desenvolvimento em resposta às condições sempre flutuantes do meio. A energia obtida através da fotossíntese deve ser utilizada parcimoniosamente e dividida entre crescimento, desenvolvimento, armazenamento e respostas a estresses bióti

4. Análise interactômica da VDAC em mitocôndrias neuronais bovina e murina / Interactomic analysis of VDAC in rat and bovine mitochondria in neuronal cells
A VDAC é a proteína mais abundante da membrana mitocondrial externa. Possui diversas funções, tais como o controle da troca de metabólitos, através da membrana, e a participação no maquinário apoptótico. Estudamos o interactoma da VDAC com as proteínas mitocondriais neuronais do cérebro bovino e murino, a fim de compreender se a expressão difere

5. The association between estimated average glucose levels and fasting plasma glucose levels
OBJECTIVE: The level of hemoglobin A1c (HbA1c), also known as glycated hemoglobin, determines how well a patient's blood glucose level has been controlled over the previous 8-12 weeks. HbA1c levels help patients and doctors understand whether a particular diabetes treatment is working and whether adjustments need to be made to the treatment. Because the HbA1

6. Germ band retraction as a landmark in glucose metabolism during Aedes aegypti embryogenesis
Background: The mosquito A. aegypti is vector of dengue and other viruses. New methods of vector control are needed and can be achieved by a better understanding of the life cycle of this insect. Embryogenesis is a part of A. aegypty life cycle that is poorly understood. In insects in general and in mosquitoes in particular energetic metabolism is well studi

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. Síntese de potenciais agentes antifúngicos inibidores de glicosamina-6-fosfato síntase.
The aminosugars are very important structural components of bacteria and fungi cell walls. Glucosamine-6-phosphate synthase (GlmS), which catalyses the first step of the aminosugar biosynthetic pathway i.e. the formation of D-glucosamine-6-phosphate from D-fructose-6-phosphate, is therefore an interesting target in the fight against microorganisms. In this w

9. Envolvimento dos quatro genes bZIPs do Grupo C de Arabidopsis thaliana na sinalização por glicose, manose e ABA / Functional analysis of the Arabidopsis Group C bZIPs homologous to the maize Opaque-2 regulator
In the model eudicot organism A. thaliana (Arabidopsis), four genes encoding bZIP transcription regulatory factors that are homologous to the maize Opaque-2 (O2) locus were identified. O2 is a key regulator of the carbon to nitrogen balance and of the prolamine type storage proteins synthesis during seed development. The Arabidopsis genes, AtbZIP9, the two p

10. Proteomic study to determination of relative expression of VDAC isoforms and characterization of hexokinase binding sites in rat, bovine and avian brain mitochondria / Estudo proteômico para determinação da expressão relativa das isoformas de VDAC e caracterização dos sítios de ligação da hexoquinase em mitocôndrias cerebrais de rato, boi e ave
The voltage dependent anion selective channels (VDACs) are a group of proteins first identified in the mitochondrial outer membrane that are able to form hydrophilic pore structures in membranes. VDAC are known to play an essential role in cellular metabolism and in the early stages of apoptosis. In mammals, three VDACs isoforms (VDAC1, 2, 3) have been ident

11. Reactive oxygen species as signaling molecules of contraction-mediated metabolic responses in skeletal muscle. / Espécies reativas de oxigênio como sinalizadores das respostas metabólicas mediadas por contração no músculo esquelético.
Contractile activity is a potent stimulus for induce changes in glucose and fatty acid metabolism in skeletal muscle. During muscle contraction, the production of reactive oxygen species (ROS) is increased. The purpose of this study was evaluate the effect of removal of ROS, induced by treatment with the antioxidant N-Acetylcysteine, on glucose uptake, activ

12. Termorregulação colonial e energética individual em abelhas sem ferrão Melipona quadrifasciata Lepeletier (Hymenoptera, Apidae, Meliponini) / Colonial thermoregulation and energetics in stingless bees Melipona quadrifasciata Lepeletier (Hymenoptera, Apidae, Meliponini).
In eusocial insects, such as stingless bees, the control of nest conditions and maintenance of the colonial microclimate are important to brood incubation, development of eggs, larvae and pupae, and survival of the colony. One of the main thermoregulatory mechanisms to control nest temperature is the microhabitat selection to build the nest, such as tree hol
