1. SYNTHESIS, CHARACTERIZATION, DFT MODELING AND IN VITRO ANTIMYCOBACTERIAL ACTIVITY ASSAYS OF A SILVER(I)-ISONIAZID COMPLEX
In the present work, a silver(I) complex with the antimycobacterial drug isoniazid (inh) is described. Elemental and thermogravimetric analyses confirmed a 1:1 metal:ligand ratio for the silver-isoniazid (Ag-inh) complex with molecular composition AgC6H7N3O·NO3. Infrared (IR) analysis suggests a bidentate coordination of isoniazid to silver by the nitrogen

2. In vitro biological activities of silver nanoparticles synthesized from Scedosporium sp. isolated from soil
One of the important fields in nanotechnology is the development of an environment friendly method for the synthesis of nanoparticles. Many approaches show that microorganisms are the most reliable tools for biosynthesis of nanoparticles compared to physical and chemical methods. In our study, fungi have been exploited for extracellular production of metal n

3. Biosynthesis and Functionalization of Bacterial Cellulose Membranes with Cerium Nitrate and Silver Nanoparticles
This work aimed to synthesize bacterial cellulose (BC) membranes functionalized with Ce(NO3)3 and silver nanoparticles (AgNPs) heat-treated in oven and autoclave. The AgNPs were characterized by TEM and the membranes were characterized by their rehydration capacity, Thermogravimetric Analysis (TGA), Scanning Electron Microscopy with Dispersive Energy Spectro

4. Effects of Light Quality and Chemical Elicitors on the Growth Parameters and Rosmarinic Acid Content of in vitro Cultures of Hyptis pectinata (L.) Poit.
Hyptis pectinata (L.) Poit is a folk medicinal species in Northeast Brazil. In this work, seedlings of H. pectinata were cultured in vitro under diverse light quality spectra and under the influence of two distinct chemical elicitors, salicylic acid and silver nitrate (SN), at concentrations of 30 and 60 μM. Growth parameters, biomass and rosmarinic acid (R

5. A comparison of the sealing abilities between Biodentine and MTA as root-end filling materials and their effects on bone healing in dogs after periradicular surgery
ABSTRACT Objectives: To compare the sealing ability and biocompatibility of Biodentine with mineral trioxide aggregate (MTA) when used as root-end filling materials. Methodology: The Cell Counting Kit-8 (CCK-8) assay was used to compare the cytotoxicity of MTA and Biodentine. Twenty-one extracted teeth with a single canal were immersed in an acidic silver

6. Influence of Silver Nitrate on Somatic Embryogenesis Induction in Arabica Coffee (Coffea arabica L.)
Abstract The influence of silver nitrate (AgNO3), benzyladenine (BAP), and indole-3-acetic acid (IAA) on low frequency somatic embryogenesis (LFSE) induction in Caturra and Catuaí arabica coffee was evaluated. For the Caturra cultivar, the production of somatic embryos was significantly increased by adding AgNO3 to the semisolid culture medium. The highest

7. [PROVISIONAL] Does the chromosomal position of 35S rDNA sites influence their transcription? A survey on Nothoscordum species (Amaryllidaceae)
Abstract 35S ribosomal DNA (rDNA) sites are the regions where the ribosomal genes 18S, 5.8S and 25S, responsible for the formation of the nucleoli, are found. The fact that rDNA sites have non-random distribution on chromosomes suggests that their position on the chromosome may influence their transcription. In order to identify if the preferentially transcr

8. First report of Trichodinella and new geographical records of trichodinids in Nile tilapia (Oreochromis niloticus) farmed in Brazil
Resumo O parasitismo intenso por tricodinídeos está frequentemente relacionado à doença grave em fazendas de peixes. Neste estudo, espécies de tricodinídeos das brânquias e da pele de tilápias do Nilo (Oreochromis niloticus) cultivadas na região centro-oeste do Brasil (estado de Goiás) foram caracterizadas morfologicamente. As lâminas secas foram

10. Effect of salicylic acid and silver nitrate on rutin production by Hyptis marrubioides cultured in vitro
RESUMO: Hyptis marrubioides (Lamiaceae) é uma planta medicinal nativa do Cerrado brasileiro. Técnicas de propagação in vitro fazem uso de elicitores para alterar as vias metabólicas, afetando a produção de moléculas qualitativa e quantitativamente. Este trabalho teve como objetivo avaliar como os elicitores abióticos ácido salicílico (SA) e nitrat

12. Estudio de la actividad antifúngica de materiales conteniendo carbón proveniente de pilas en desuso
ABSTRACT The large number of batteries that are discarded and the environmental impact that the inadequate disposition of the waste of the same produces impelled to its recycling. Both alkaline and zinc-carbon batteries have as their main components zinc and carbon mixed with other oxides, in their internal fill. In this work, the silica synthesis was carrie
