1. Is Drosophila nasuta Lamb (Diptera, Drosophilidae) currently reaching the status of a cosmopolitan species?
ABSTRACT In early March 2015, three males and two females of one unknown species of Drosophila were collected from a compost pile and some garbage cans in the west region of the city of São Paulo, state of São Paulo, Brazil. Morphologically it is easily identified by the presence of the following conspicuous features: a brownish dorsal stripe along pleura,

2. Recombinogenic activity of Pantoprazole® in somatic cells of Drosophila melanogaster
Pantoprazole® is one of the leading proton pump inhibitors (PPIs) used in the treatment of a variety of diseases related to the upper gastrointestinal tract. However, studies have shown an increased risk of developing gastric cancer, intestinal metaplasia and hyperplasia of endocrine cells with prolonged use. In the present study, the somatic mutation and r

3. Effects of artichoke (Cynara scolymus) leaf and bloom head extracts on chemically induced DNA lesions in Drosophila melanogaster
The genotoxicity of bloom head (BHE) and leaf (LE) extracts from artichoke (Cynara scolymus L.), and their ability to modulate the mutagenicity and recombinogenicity of two alkylating agents (ethyl methanesulfonate - EMS and mitomycin C - MMC) and the intercalating agent bleomycin (BLM), were examined using the somatic mutation and recombination test (SMART)

4. Antimutagenic and antirecombinagenic activities of noni fruit juice in somatic cells of Drosophila melanogaster
Noni, nome Havaiano da fruta de Morinda citrifolia L., é uma planta medicinal e tradicional da Polinésia amplamente usada para o tratamento de muitas doenças entre as quais artrite, diabetes, asma, hipertensão e câncer. Neste trabalho, um suco comercial de noni (TNJ) foi avaliado para suas atividades protetoras contras as lesões induzidas por mitomicin

5. Spermatogenesis of Zaprionus indianus and Zaprionus sepsoides (Diptera, Drosophilidae): cytochemical, structural and ultrastructural characterization
Zaprionus indianus is a drosophilid native to the Afrotropical region that has colonized South America and exhibits a wide geographical distribution. In contrast, Z. sepsoides is restricted to certain African regions. The two species differ in the size of their testes, which are larger in Z. indianus than in Z. sepsoides. To better understand the biology and

6. Avaliação da expressão transiente do gene da glicoproteína do vírus da raiva (RVGP) em células de inseto da linhagem Drosophila melanogaster S2
A raiva é uma enfermidade causada por um vírus do gênero Lyssavirus que afeta várias espécies de mamíferos. Esta doença apresenta um alto custo social e econômico principalmente em países em desenvolvimento. Na superfície do vírus da raiva está localizada a glicoproteína do vírus, reconhecida como antígeno capaz de conferir resposta imunológi

7. Avaliação do potencial mutagênico, recombinogênico e carcinogênico do Orlistat em células somáticas de Drosophila melanogaster
CHAPTER 2: Orlistat is the first compound of a new pharmacological class which limits dietary fat absorption by inhibiting gastric and pancreatic lipases. It does not affect the neuronal circuits regulating appetite, and its action consists basically of obstructing digestion of dietary triglycerides. Recent researches suggest that orlistat stops the growth o

8. Rat Dlx5 is expressed in the subventricular zone and promotes neuronal differentiation
The molecular mechanisms and potential clinical applications of neural precursor cells have recently been the subject of intensive study. Dlx5, a homeobox transcription factor related to the distal-less gene in Drosophila, was shown to play an important role during forebrain development. The subventricular zone (SVZ) in the adult brain harbors the largest ab

9. Cultura de células de Drosophila melanogaster (S2) em processo contínuo. / Culture of Drosophila melagogaster cells (S2) in continuous culture.
As células de Drosophila melanogaster (S2) têm sido utilizadas como sistemas de expressão de proteínas recombinantes. Neste trabalho foi utilizada uma linhagem S2 geneticamente modificada com vetores de expressão para a produção da glicoproteína do vírus da raiva (GPV). O principal objetivo deste trabalho foi avaliar o comportamento destas células

10. Kinetic study of Drosophila melanogaster cells transfected to produce the rabies vírus glycoprotein in bioreactor / Estudo cinético de células de Drosophila melanogaster transfectadas para a produção da glicoproteína da raiva em biorreator
The interest in using insect cells to produce complex proteins is due to its ease of cultivation and its glycosylation pattern equivalent to that of mammalian cells systems. The objective of this work was to identify the limiting or inhibiting factors for the production of a rabies virus glycoprotein (RVGP), expressed in the cytoplasmatic membrane of a trans

11. Expression of DLK1 and MEG3 genes in porcine tissues during postnatal development
The Drosophila-like homolog 1 (DLK1), a transmembrane signal protein similar to other members of the Notch/Delta/Serrate family, regulates the differentiation process in many types of mammalian cells. Callipyge sheep and DLK1 knockout mice are excellent examples of a fundamental role of the gene encoding DLK1 in muscle growth and fat deposition. DLK1 is loca

12. Sequence and expression pattern of the germ line marker vasa in honey bees and stingless bees
Queens and workers of social insects differ in the rates of egg laying. Using genomic information we determined the sequence of vasa, a highly conserved gene specific to the germ line of metazoans, for the honey bee and four stingless bees. The vasa sequence of social bees differed from that of other insects in two motifs. By RT-PCR we confirmed the germ lin
