1. Pro and antioxidant aspects of flavoproteins from Xylella fastidiosa / Investigação de facetas pró e antioxidantes de flavoproteínas de Xylella fastidiosa
As flavoproteinas AhpF (Alquil Hidroperoxido Redutase subunidade F) e TrxR (Tiorredoxina Redutase) sao membros da familia piridina dissulfeto redutase e possuem atividade dissulfeto redutase as custas de NAD(P)H. A proteina TrxR e responsavel pela reducao de Tiorredoxina (Trx) que participa do ciclo catalitico de grande parte das enzimas da familia peroxirre

2. Functional characterization of a new antioxidant protein: Ohr (Organic Hydroperoxide Resistance Protein). Pathways of reduction and expression in Xylella fastidiosa / Caracterização funcional de uma nova proteína antioxidante: Ohr (Organic Hydroperoxide Resistance Protein). Vias de redução e expressão em Xylella fastidiosa
Xylella fastidiosa é uma bactéria gram-negativa, colonizadora do xilema de plantas economicamente importantes, sendo responsável por diversas patogenias como a doença de Pierce em videiras e a clorose variegada dos citros (CVC). Plantas, ao serem infectadas por patógenos, dispõem de um maquinário de defesa que inclui a geração de espécies reativas

3. Chemical synthesis and biological activities of analogues of 2',5'-oligoadenylates containing 8-substituted adenosine derivatives.
The synthesis of sequence-specific 2'-5'-oligonucleotides and analogues of 2'-5' linked oligoadenylates containing 8-substituted adenosine derivatives [8-hydroxypropyladenosine (AHPr) and 8-hydroxyadenosine (AOH)] is reported. The reaction of 5'-phosphoroimidazolidate of 8-substituted adenosines under conditions of lead ion catalyst did not give the correspo

4. Estrogen maintains trabecular bone volume in rats not only by suppression of bone resorption but also by stimulation of bone formation.
Estrogen is generally considered to maintain bone mass through suppression of bone resorption. We have previously demonstrated that administration of pharmacologic doses of estrogen increases bone formation in ovary-intact rats. To assess the effects of physiological concentrations of estrogen on bone formation, estrogen was administered to ovariectomized ra

5. Cooperative binding of lactose and the phosphorylated phosphocarrier protein HPr(Ser-P) to the lactose/H+ symport permease of Lactobacillus brevis.
Lactobacillus brevis accumulates lactose and nonmetabolizable lactose analogues via sugar/H+ symport, but addition of glucose to the extracellular medium results in rapid efflux of the free sugar from the cells due to the uncoupling of sugar transport from proton transport. By using vesicles of L. brevis cells, we recently showed that these regulatory/effect
