1. In vitro antifungal activity of organic compounds derived from amino alcohols against onychomycosis
Abstract Onychomycosis is a fungal infection of the nail caused by high densities of filamentous fungi and yeasts. Treatment for this illness is long-term, and recurrences are frequently detected. This study evaluated in vitro antifungal activities of 12 organic compounds derived from amino alcohols against standard fungal strains, such as Trichophyton rubru

2. Tissue dissolution and modifications in dentin composition by different sodium hypochlorite concentrations
ABSTRACT Sodium hypochlorite (NaOCl) remains the most used irrigation solution during root canal preparation because of characteristics such as wide-spectrum antimicrobial activity and organic tissue dissolution capacity. However, these solutions can alter dentin composition and there is no consensus on the optimal concentration of NaOCl to be used. Objecti

3. Elaboração e caracterização de blendas de amido fosforilado com quitosana e PVA
The aims of this study were to produce films from phosphorylated starch/chitosan/PVA blends and evaluate their physicochemical properties. The film properties were dependent on the starch percentage in the blend. The infrared spectra of the blends showed the appearance of bands at 1716 and 1733 cm-1 (stretching C = O of PVA acetate residues) and 1556 cm-1 (a

4. CROMATOGRAFIA POR INTERAÇÕES HIDROFILICAS (HILIC): ESTADO DA ARTE E APLICAÇÕES
Hydrophilic interaction liquid chromatography (HILIC) has been gaining increased attention for its effective separation of highly polar compounds, which include carbohydrates, amino acids, pharmaceutical compounds, proteins, glycoproteins, nucleosides, etc. Polar compounds are usually poorly retained on reverse-phase liquid chromatography (RP-HPLC) columns o

6. Caracterização comparativa do esmalte de dentes decíduos e permanentes por Espectroscopia Raman
The aim of this study was the characterization of primary and permanent teeth enamel, producing comparison parameters to future studies. The Raman spectroscopy identifies the content of organic and inorganic matters through polarized change associated with molecule vibration modes. Third permanent (n=15) and second primary molars (n=15) were used. Samples we

7. Synthesis, spectral studies and catalytic activity of ruthenium(II) complexes with organic amide ligands
Doze novos complexos hexacoordenados de rutênio(II) com amidas, [RuH(CO)(PPh3)2(L2 )], foram sintetizados a partir do precursor [RuH2(CO)(PPh3)3]. Esses complexos foram caracterizados por análise elementar e por espectroscopias no UV-vis, no infravermelho e RMN de ¹H, 13C e 31P. Fórmulas moleculares e estruturas octaédricas foram propostas para os produ

8. Investigação das características tribológicas e ambientais de termoplásticos de engenharia especiais para uso em materiais de atrito. / Investigation of tribological and environmental characteristics of high performance thermoplastics to friction materials.
Organic clutch friction facings are basicly composed of an organic matrix, fillers, solid lubricants and reinforcing fibers. An organic matrix has a structural function and has a large influence over the tribological properties of the system (coefficient of friction and wear rate in both, friction material as for the metal counterpart). Based on the automoti

9. Estudo de metalofármacos antiinflamatórios de cobre e dos materiais híbridos resultantes de suas imobilizações no hidróxido duplo lamelar hidrotalcita: síntese, caracterização e avaliação da atividade farmacológica / Studies of Anti-inflammatory Copper-based Drugs and Corresponding Hybrid Materials from their Immobilization on the Layered Double Hydroxide Hydrotalcite: Synthesis, Characterization and Evaluation of Pharmacological Activities
Non-steroidal anti-inflammatory drugs are widely consumed to treat inflammatory diseases and pain but their clinical use are limited due to serious side-effects on the gastrointestinal tract. The bioactivity of metal complexes exhibits great interest in metal-based drug research. Cu(II)-NSAID compounds show good anti-inflammatory property and decreased side-

10. Metalloporhyrins as Biomimetical MOdels of Cytochrome P450 in the Oxidation of Pesticides / Metaloporfirinas como modelos biomiméticos do citocromo P450 na oxidação de pesticidas"
In this work we investigated the ability of metalloporphyrin model systems to mimic the action of cytochrome P450 in the oxidation of a herbicide, atrazine. To this end, we employed the second generation commercially available metalloporphyrins metal (III) 5,10,15,20-tetrakis(2,6-dichlorophenyl)porphyrin chloride [M(TDCPP)Cl] and metal (III) 5,10,15,20- tetr

11. Metabolite and light regulation of metabolism in plants: lessons from the study of a single biochemical pathway
We are using molecular, biochemical, and genetic approaches to study the structural and regulatory genes controlling the assimilation of inorganic nitrogen into the amino acids glutamine, glutamate, aspartate and asparagine. These amino acids serve as the principal nitrogen-transport amino acids in most crop and higher plants including Arabidopsis thaliana.

12. Nonconventional amide bond formation catalysis: programming enzyme specificity with substrate mimetics
This article reports on the design and characteristics of substrate mimetics in protease-catalyzed reactions. Firstly, the basis of protease-catalyzed peptide synthesis and the general advantages of substrate mimetics over common acyl donor components are described. The binding behavior of these artificial substrates and the mechanism of catalysis are furthe
