13. Biology and fertility life table of Bactrocera carambolae on grape and acerola
ABSTRACT Bactrocera carambolae Drew & Hancock (Diptera: Tephritidae), native of Southeast Asia, is present in Brazil but restricted to Amapá, Pará and Roraima, where it has quarantine pest status. The possible dispersion to other fruit producing regions of Brazil could cause damages, including for exportation, due to quarantine restrictions imposed by frui

15. Composição granulométrica do filtro ascendente para pós-tratamento de lixiviado de aterro sanitário
RESUMO O lixiviado de aterro sanitário apresenta composição variável e complexa e pode ter elevadas concentrações de nitrogênio amoniacal e matéria orgânica biodegradável e recalcitrante. Devido ao potencial altamente poluidor dos lixiviados estabilizados, além do tratamento biológico convencional, faz-se necessária, em alguns casos, a realizaç

16. Composition, density and biomass of fish community from the surf zone as a function of the lunar cycle at Miramar Beach in Cabedelo, Paraíba
RESUMO A influência das fases lunares sobre a ictiofauna tem sido pouco estudada na zona de arrebentação. Nesse estudo, foram avaliadas, o número de espécies, densidade e a biomassa da ictiofauna em função da lua. Foram capturadas 49 espécies distribuídas em 24 famílias em duas áreas na Praia de Miramar. A densidade foi significativamente elevada

17. Optimization of ultrasound-assisted extraction of bioactive compounds from jabuticaba (Myrciaria cauliflora) fruit through a Box-Behnken experimental design
Abstract Jabuticaba is a very popular fruit in Brazil being a great source of compounds with considerable biological activities. Novel optimized ultrasound-assisted extraction (UAE) methods have been proposed for anthocyanins and total phenolic compounds from jabuticaba. A Box–Behnken experimental design (BBD) with a response surface methodology (RSM) was

19. Nanoemulsion containing essential oil from Xylopia ochrantha Mart. produces molluscicidal effects against different species of Biomphalaria (Schistosoma hosts)
BACKGROUND This work describes a chemical study of the essential oil from leaves of Xylopia ochrantha, an endemic Annonaceae species from Brazil, and its activity against Biomphalaria species. Considering its poor solubility in aqueous medium, the essential oil was nanoemulsified to evaluate its action on controlling some mollusc species of genus Biomphala

20. BjussuLAAO-II induces cytotoxicity and alters DNA methylation of cell-cycle genes in monocultured/co-cultured HepG2 cells
Abstract Background: The use of animal venoms and their toxins as material sources for biotechnological applications has received much attention from the pharmaceutical industry. L-amino acid oxidases from snake venoms (SV-LAAOs) have demonstrated innumerous biological effects and pharmacological potential against different cancer types. Hepatocellular carc

21. A simulation model to evaluate the economic consequences of insemination programs in dairy herds: timed artificial insemination and sex-sorted semen
ABSTRACT The objective of this study was to develop a simulation model to analyse the technical, economic, and financial performance of using different reproductive strategies in dairy herds. Strategies simulated were: artificial insemination (AI) using conventional semen after oestrus detection (AIC), AI using sex-sorted semen after oestrus detection (AIS),

22. Benefits Associated with the Interaction of Endophytic Bacteria and Plants
ABSTRACT The endophytic bacteria belong to a larger group of microorganisms that have their life-cycle partly or entirely inside the plant and are located in intra and inter-cellular spaces or in the vascular tissue. These bacteria can be found colonizing aerial parts or roots. This review aims to analyze the colonization strategies of endophytic bacteria th

23. Screening a bacterium and its effect on the biological degumming of ramie and kenaf
ABSTRACT: Biological degumming is an eco-friendly, efficient, high-quality and low-cost method that has become the leading bast fiber degumming technology. However, bacterial strains with short degumming cycles, high gum removal rates and small fiber damage are few. To screen high quality microbial resources with bast-fiber biological degumming function, soi

24. Glycemic control in minks with tendency to obesity in the perinatal period with the use of HbA1C
ABSTRACT The objective of this study was to investigate the usefulness of HbA1C as a test in monitoring the long-term glycemic control during the perinatal period in minks with the tendency to obesity. On the scanbrown mink farm, screening research on one-year-old females showing predilections to obesity was conducted. In the first year of the experiment, 12
