38. Efficiency of Vegetable Oils in Wood Resistance to Cryptotermes brevis Termites
ABSTRACT Natural products have been studied in order to ensure environmental sustainability, human health, and diminish the use of traditional products. The objective of this study was to evaluate the efficiency of pure andiroba (Carapa guianensis), copaiba (Copaifera langsdorffii) and jatropha (Jatropha curcas) oils and enriched with iodine (I2) on the biol

39. Influência da idade do lodo na colmatação das membranas em um biorreator à membrana tratando esgoto sanitário
RESUMO O presente estudo avaliou o efeito da idade do lodo (θc) no potencial incrustante do licor misto em um biorreator à membrana (BRM) tratando esgoto sanitário. Tal avaliação foi conduzida em BRM construído em escala de bancada, com volume útil de 15 L, operado por 420 dias na modalidade de batelada sequencial. Durante o período experimental, for

40. Synthesis of some novel pyrimidine, thiophene, coumarin, pyridine and pyrrole derivatives and their biological evaluation as analgesic, antipyretic and anti-inflammatory agents
Pyrimidine derivative 3 was afforded through the reaction of compound (1) with 5-ureidohydantion (2). Product 3 underwent a cyclization to produce fused pyrimidine derivative 7, although the latter product 7 was synthesized through one step via the reaction of compound (1) with 5-ureidohydantion (2) using another catalyst. Compound 3 was oriented to react wi

41. Reduction Potential of RuIII-Based Complexes with Potential Antitumor Activity and Thermodynamics of their Hydrolysis Reactions and Interactions with Possible Biological Targets: a Theoretical Investigation
In this article density functional theory (DFT)-based calculations were employed to investigate the electrochemistry of the antitumor ruthenium complexes trans-tetrachloro(dimethylsulfoxide)imidazole ruthenate(III) (NAMI-A) and trans-[tetrachlorobis(1.-indazole)ruthenate(III)] (KP1019), their hydrolysis products as well as their interactions with biological

42. NANOTOXICOLOGIA DE NANOPARTÍCULAS DE PRATA: TOXICIDADE EM ANIMAIS E HUMANOS
Silver nanoparticles (AgNPs) have important antimicrobial activity. These nanoparticles are present in several commercial products, leading to human and environmental exposure. This review presents a critical view of the toxic effects of Ag NPs on in vitro and in vivo biological models. It is noteworthy that the toxicity of AgNPs is dependent on several para

43. AVANÇOS RECENTES EM BIOSSÍNTESE COMBINATÓRIA DE POLICETÍDEOS: PERSPECTIVAS E DESAFIOS
Natural products continue to inspire scientists on the search for biological active structures. Recent advances in synthetic biology allow modifying genes to extend structural diversity present on natural products by changing important functional groups guided through genetic information. In this context, polyketides synthases (PKS) represent a class of enzy

44. A globally applicable PCR-based detection and discrimination of BK and JC polyomaviruses
ABSTRACT BKV and JCV belong to the Polyomaviridae family and are opportunistic agents associated with complications in immunocompromised individuals. Although a single screening assay for both viruses would be convenient, the diversity of BKV and JCV serotypes and genotypes is a methodological challenge. In this paper, we developed a PCR method able to detec

45. Isoflavonoid composition and biological activity of extracts from soybean seedlings treated by different elicitors
Abstract Time-course and dose-response experiments were carried out to establish the ability for synthesizing isoflavonoids of soybean seedlings (cv. Soyica P34) treated with salicylic (SA) and isonicotinic acids (INA). Then, 25 structurally-related compounds were evaluated for their isoflavonoid-eliciting activity. Next, the antimicrobial and antioxidant ac

46. The potential contribution of the natural products from Brazilian biodiversity to bioeconomy
ABSTRACT The development of our society has been based on the use of biodiversity, especially for medicines and nutrition. Brazil is the nation with the largest biodiversity in the world accounting for more than 15% of all living species. The devastation of biodiversity in Brazil is critical and may not only cause the loss of species and genes that encode en

47. Clinical and epidemiological use of nested PCR targeting the repetitive element IS1111 associated with the transposase gene from Coxiella burnetii
ABSTRACT Q fever is a worldwide zoonosis caused by Coxiella burnetii—a small obligate intracellular Gram-negative bacterium found in a variety of animals. It is transmitted to humans by inhalation of contaminated aerosols from urine, feces, milk, amniotic fluid, placenta, abortion products, wool, and rarely by ingestion of raw milk from infected animals.

48. Effect of sulfonylurea tribenuron methyl herbicide on soil Actinobacteria growth and characterization of resistant strains
ABSTRACT Repeated application of pesticides disturbs microbial communities and cause dysfunctions on soil biological processes. Granstar® 75 DF is one of the most used sulfonylurea herbicides on cereal crops; it contains 75% of tribenuron-methyl. Assessing the changes on soil microbiota, particularly on the most abundant bacterial groups, will be a useful a
