1. Biologically Active Volatile Organic Compounds (VOCs) Produced by Rhizospheric Actinobacteria Strains Inhibit the Growth of the Phytopathogen Colletotrichum musae
The antifungal potential of volatile organic compounds (VOCs) produced by actinobacterial strains Streptomyces sp. (ACTB-77) and Amycolatopsis sp. (ACTB-290) from the rhizosphere of Caatinga plants against Colletotrichum musae was investigated. VOCs produced by these microorganisms (axenic and co-culture) were investigated using headspace-solid phase micro-e

3. Efficient Synthesis and Antimicrobial Activities of Long Alkyl Chain Trifluoromethyl-1H-pyrazol-1-(thio)carboxamides and Trifluoromethyl-1H-pyrazol-1-yl-thiazoles
The synthesis of 3-alkyl-5-trifluoromethyl-1H- pyrazole-1-carboxamides, 3-alkyl-5-trifluoromethyl-1H-pyrazole-1-thiocarboxamides, and 2-(3-alkyl-5-trifluoromethyl-1H-pyrazol-1-yl)-thiazoles derivatives are reported. [3 + 2] cyclocondensations for a series of long alkyl chain 1,1,1-trifluoro-4-methoxyalk-3-en-2-ones and semicarbazide or thiosemicarbazide were

4. Multivariate Optimization of Extraction Variables of PAH in Particulate Matter (PM10) in Indoor/Outdoor Air at Campos dos Goytacazes, Brazil
Polycyclic aromatic hydrocarbons (PAH) are products of incomplete combustion of biomass and fossil fuels, that are produced on a larger scale by anthropogenic sources. Burning sugarcane plantations can be a source of atmospheric PAH in regions where this culture predominates. Campos dos Goytacazes, Brazil, is surrounded by sugarcane crops that still use fire

5. Self-Assembled Nanoparticles of Diruthenium(II,III)-Ibuprofen Anticancer Metallodrug
The diruthenium(II,III)-ibuprofen (RuIbp) metallodrug shows anticancer activity in vitro and in vivo. The encapsulation into lipid nanoparticles enhanced the efficacy in glioblastoma, breast and prostate cancer cells. Here we report data for RuIbp hydrophobicity, solubility in alcohol/water, and behavior in 1-5% ethanol/water and ethanol/cell culture medium.

6. “Half-Sandwich”/RuII Anticancer Complexes Containing Triphenylphosphine and p-Substituted Benzoic Acids
Mononuclear and binuclear RuII/arene/triphenylphosphine complexes with p-substituted benzoic acid derivatives were prepared and characterized. These monocationic complexes of type [Ru(η6-p-cymene)(PPh3)L] (L = benzoic acid (1), p-hydroxybenzoic acid (2), p-nitrobenzoic acid (3) and terephthalic acid (4)) were characterized using various techniques, such as

7. DETERMINATION OF THE PESTICIDES IN WATER USED IN THE CULTURE AND PROCESSING OF POTATOES
The contamination of water bodies by pesticide residues through direct flow, leaching and other methods has motivated the development of analytical methods for the determination of these compounds in water. A vortex-assisted liquid-liquid microextraction method followed by gas chromatography coupled to mass spectrometry for the determination of anilazine, li

8. Pumilacidins A-E from Sediment-Derived Bacterium Bacillus sp. 4040 an Their Antimicrobial Activity Evaluation
Marine strains of Bacillus are known to produce secondary metabolites different from that accumulated by their terrestrial counterparts, for example, lipopeptides such as surfactins, iturins and fengycins, which exhibit a variety of biological activities. Another important class of lipopeptides are pumilacidins, identified specially from Bacillus pumilus str

9. Aromatic Polyketides and Macrolides from Microsphaeropsis arundinis
The endophytic fungus Microsphaeropsis arundinis was isolated from the capitula of the tropical plant Paepalanthus planifolius (Eriocaulaceae). The fungus was cultivated in seven different media, and the ethyl acetate extracts were tested against tumor cell lines using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide MTT assay. The culture wa

10. Tuberculous Osteomyelitis Mimicking a Lytic Bone Tumor: Report of Two Cases and Literature Review
Resumo A osteomielite tuberculosa é uma forma incomum de tuberculose (TB) e o acometimento isolado da articulação do punho pelo TB é particularmente raro. Os sintomas e a manifestação clínica imitam outras doenças; portanto, um diagnóstico cuidadoso é necessário. Os autores apresentam dois casos de pacientes com massa nas partes moles e lesão ós

11. Competitive interaction and economic injury level of Urochloa plantaginea in corn hybrids
RESUMO A identificação da habilidade competitiva de híbridos de milho e do nível de dano econômico (NDE) ocasionado pelo papuã (Urochloa plantaginea) torna-se importante para a adoção do manejo integrado dessa planta daninha. Diante disso, objetivou-se com este trabalho avaliar a interferência e o NDE de papuã infestante de híbridos de milho. Os t

12. Lótman continua a surpreender: revoluções e emoções coletivas
Resumo Entre 1988 e 1993, Iúri M. Lótman formulou algumas proposições sobre “a voz da massa anônima”: uma voz coletiva que, em certas situacões ligadas a crises de caráter cultural, é portadora de paixões violentas que podem produzir interferências profundas no curso da história. Em seus últimos trabalhos, o semioticista russo postulou, diant
