1. Synthesis of new α-amino nitriles with insecticidal action on Aedes aegypti (Diptera: Culicidae)
Abstract Aedes aegypti is the principal vector of arboviral pathogens that may cause diseases as dengue fever, chikungunya and zika. The harmful environmental effects of commercial pesticides coalesced with the development of insecticide-resistant populations encourage the discovery and generation of new alternative products as a tool to reduce the incidence

2. Use of Component Mode Synthesis and Axial Splits in Ducts for Noise Control of Higher Order Duct Mode / Utilização de síntese modal de componentes e particionamento axial de dutos para controle dos modos acústicos de alta ordem
In this study, the proposal of this work is centered in the noise reduction in ducts that became, over the years, a field of intense application. The traditional approach to acoustic noise control in ducts uses passive techniques and fixed reactive silencers to mitigate the noise. In this moment, the Active Control of Noise (ANC) is an attractive approach to

3. Damage detection in complex structures using Component Mode Synthesis and Ritz vectors / Detecção de falhas em estruturas complexas usando sintese modal dos componentes e vetores de Ritz
This work explores the use of Component Mode Synthesis methods (CMS), Minimum Rank Perturbation Theory (MRPT), and Ritz Realization AIgorithm (RRA) as a structural damage detection tooI. The CMS consists in to modeling individual components of a structure separately and then to couple them to form an assembled system. CMS methods can be generalized to allow

4. Translesion synthesis is the main component of SOS repair in bacteriophage lambda DNA.
Agents that interfere with DNA replication in Escherichia coli induce physiological adaptations that increase the probability of survival after DNA damage and the frequency of mutants among the survivors (the SOS response). Such agents also increase the survival rate and mutation frequency of irradiated bacteriophage after infection of treated bacteria, a ph

5. Mediator proteins orchestrate enzyme-ssDNA assembly during T4 recombination-dependent DNA replication and repair
Studies of recombination-dependent replication (RDR) in the T4 system have revealed the critical roles played by mediator proteins in the timely and productive loading of specific enzymes onto single-stranded DNA (ssDNA) during phage RDR processes. The T4 recombination mediator protein, uvsY, is necessary for the proper assembly of the T4 presynaptic filamen

6. Mode of action of tubulozoles against Plasmodium falciparum in vitro.
The mode of action of the tubulozole isomers, recently recognized as a new class of potential antimalarial agents, was investigated. Whereas neither glycolysis, protease activity, or nucleic acid biosynthesis was primarily affected, protein biosynthesis decreased soon after addition of the drug. Inhibitors of protein biosynthesis, however, did not show syner

7. Cryptopleurine Resistance: Genetic Locus for a 40S Ribosomal Component in Saccharomyces cerevisiae
Mutants resistant to the phenanthrene alkaloids tylophorine, tylocrebrine, and cryptopleurine have been isolated from the yeast Saccharomyces cerevisiae. A single recessive nuclear gene was responsible for resistance. This resistance locus, cry, was closely linked to the mating locus (2.2 centimorgans). The resistance was ribosomal and was due to an altered

8. Ku autoantigen is the regulatory component of a template-associated protein kinase that phosphorylates RNA polymerase II.
The carboxyl-terminal domain of RNA polymerase II contains a tandemly repeated heptapeptide sequence. Previous work has shown that this sequence is phosphorylated at multiple sites by a template-associated protein kinase, in a reaction that is closely associated with the initiation of RNA synthesis. We have purified this kinase to apparent homogeneity from h

9. Mode of action of staphylococcal leukocidin: effects of the S and F components on the activities of membrane-associated enzymes of rabbit polymorphonuclear leukocytes.
The cytotoxic action of the S component of leukocidin from Staphylococcus aureus on rabbit polymorphonuclear leukocytes was supported by the following observations, (i) Leukocytes displayed a large chemotactic response to the S component (10(-10) M) as well as to the chemotactic factor N-formylmethionylleucylphenylalanine (10(-11) M). (ii) The S component st

10. Expression of Bottom Component RNA of Cowpea Mosaic Virus in Cowpea Protoplasts
Upon inoculation of cowpea protoplasts with the bottom component of cowpea mosaic virus, at least six virus-induced proteins (with sizes of 170, 110, 87, 84, 60, and 32 kilodaltons) are synthesized, but not the capsid proteins (37 and 23 kilodaltons). These bottom-component-induced proteins were studied with respect to their genetic origin and mode of synthe

11. Inactivation of Mg Chelatase during Transition from Anaerobic to Aerobic Growth in Rhodobacter capsulatus
The facultative photosynthetic bacterium Rhodobacter capsulatus can adapt from an anaerobic photosynthetic mode of growth to aerobic heterotrophic metabolism. As this adaptation occurs, the cells must rapidly halt bacteriochlorophyll synthesis to prevent phototoxic tetrapyrroles from accumulating, while still allowing heme synthesis to continue. A likely con

12. Mutational analysis of genes of the mod locus involved in molybdenum transport, homeostasis, and processing in Azotobacter vinelandii.
DNA sequencing of the region upstream from the Azotobacter vinelandii operon (modEABC) that contains genes for the molybdenum transport system revealed an open reading frame (modG) encoding a hypothetical 14-kDa protein. It consists of a tandem repeat of an approximately 65-amino-acid sequence that is homologous to Mop, a 7-kDa molybdopterin-binding protein
