25. Evaluation of surfactant activity and emulsifying of Pea protein isolate (Pisum sativum L.) obtained by the spray dryer
ABSTRACT This study evaluates the biosurfactant activity and emulsification ability of pea proteins isolated (Pisum sativum L.). The results showed that aqueous solutions containing the pea proteins isolated (PPI) reduce the water surface tension to 47mN/m, approximately. The use of spray dryer does not change the surfactant activity of the PPI because surfa

28. Optimum sample size in quantitative characteristics of seeds of polyembrynic mango
Abstract Determining the sample size in a scientific investigation is important because it gives reliability in the results together with the efficiency in the use of resources and optimization of time. Polyembryony is a characteristic that allows to obtaining clonal and zygotic plants in the same seed. In mango this characteristic is presented, however, th

29. Morphometric and molecular differences among Calvertius tuberosus (Coleoptera: Curculionidae) populations associated with Andean and coastal populations of Araucaria araucana in the La Araucanía Region, Chile
Abstract Calvertius tuberosus (Curculionidae) lives exclusively on Araucaria araucana trees (commonly known as pehuen) in southern Chile. In this study, morphometric and molecular genetic analyses of Andean and coastal populations of C. tuberosus were performed to evaluate evolutionary divergence associated with the discontinuity of the Araucaria forest betw

30. PERSPECTIVAS DA QUÍMICA MEDICINAL PARA O SÉCULO XXI: DESAFIOS E OPORTUNIDADES
In the 21st century, medicinal chemists will face many challenges to improve the quality of life of populations. The challenges consist of emerging infectious (ex. bacterial, viral and parasite infections) and non-communicable diseases (ex. autoimmune, Alzheimer disease, Parkinson’s disease) that will require innovative technologies (ex. microfluidics, nan

31. Development and characterization of a packaging cell line for pseudo-infectious yellow fever virus particle generation
Abstract INTRODUCTION: Pseudo-infectious yellow fever viral particles (YFV-PIVs) have been used to study vaccines and viral packaging. Here, we report the development of a packaging cell line, which expresses the YFV prM/E proteins. METHODS: HEK293 cells were transfected with YFV prM/E and C (84 nt) genes to generate HEK293-YFV-PrM/E-opt. The cells were

36. Isolation and Probiotic Potential of Lactobacillus Salivarius and Pediococcus Pentosaceus in Specific Pathogen Free Chickens
ABSTRACT This study was conducted to isolate Lactobacillus salivarius and Pediococcus pentosaceus strains from cecal content and investigate their probiotic potential in specific pathogen free (SPF) chickens. L. salivarius and P. pentosaceus strains were isolated from the cecal content of SPF chickens and identified by 16s rDNA sequence analysis by BLAST ana
