1. Effects of Polycyclic Aromatic Hydrocarbon Pendant-Armed Ligands on the Catecholase Activity of Dinuclear Copper(II) Complexes
Herein, we present three new binuclear copper(II) complexes containing different polycyclic aromatic hydrocarbons, able to catalyze the oxidation of 3,5-di-tert-butylcathecol, a model substrate for catechol oxidase. The ligands and complexes were successful characterized in solid and solution states. The structure of C1 was determined by X-ray crystallograph

2. CYTOTOXIC EFFECTS OF DULOXETINE ON MKN45 AND NIH3T3 CELL LINES AND GENOTOXIC EFFECTS ON HUMAN PERIPHERAL BLOOD LYMPHOCYTES
RESUMO CONTEXTO: O câncer gástrico é a segunda principal causa de morte relacionada ao câncer globalmente. Infelizmente, a taxa de sobrevivência dos pacientes com câncer gástrico que se submeteram à quimioterapia após a cirurgia, tem sido inferior à metade. Além disso, a quimioterapia tem muitos efeitos colaterais. Evidências atuais sugerem que

3. Molecular Diagnostics of Dengue by Reverse Transcription-Loop Mediated Isothermal Amplification (RT-LAMP) in Disposable Polyester-Toner Microdevices
Dengue is one of the most prevalent infectious tropical diseases in the world, with high incidence in over 100 countries. Rapid and reliable diagnosis of dengue is of great importance for public health. To simplify molecular diagnostics, isothermal amplification techniques have recently emerged as an alternative to conventional methods of deoxyribonucleic ac

4. Characterization of Decellularized Human Pericardium for Tissue Engineering and Regenerative Medicine Applications
Resumo Fundameto: O enxerto de pericárdio pode ser usado em muitos procedimentos de correção cirúrgica. Uma das estratégias da engenharia tecidual é o processo de descelularização. No entanto, embora esse processo diminua a resposta imunogênica, a descelularização pode modificar tanto o comportamento como a composição da matriz extracelular nat

5. Assessment of toxicity and oxidative DNA damage of sodium hypochlorite, chitosan and propolis on fibroblast cells
Abstract The objective of this study was to evaluate and compare the cytotoxicity and genotoxicity on human fibroblast cell lines of sodium hypochlorite (NaOCl), chitosan and propolis as root canal irrigating solutions. Human fibroblast cells were exposed to chitosan, propolis and NaOCl for 4 and 24 h. Cell viability was assessed by 2,3-bis-(2-methoxy-4-nitr

6. Synthesis and antimicrobial activity of new amino derivatives of pyrano[4’’,3’’:4’,5’]pyrido[3’,2’:4,5]thieno[3,2-d]pyrimidine
ABSTRACT Annulated thienopyrimidine derivatives attracted big interest of the scientific community due to their broad spectrum of biological activities among which are the inhibition of phosphodiesterase, antiproliferative and antimicrobial activities. As a continuation of our studies on the synthesis and biological activity of fused thieno[3,2-d]pyrimidine

7. Isolation, identification, and biocontrol of antagonistic bacterium against Botrytis cinerea after tomato harvest
ABSTRACT Tomato is one of the most important vegetables in the world. Decay after harvest is a major issue in the development of tomato industry. Currently, the most effective method for controlling decay after harvest is storage of tomato at low temperature combined with usage of chemical bactericide; however, long-term usage of chemical bactericide not onl

11. Characterization of Polylactide-Stabilized Gold Nanoparticles and Its Application in the Fabrication of Electrochemical DNA Biosensors
In this work, two different approaches to gold nanoparticles (AuNPs) have been explored for the modification of screen-printed electrode based on AuNPs and AuNPs stabilized with polylactic acid (PLA). The modified substrate has been characterized using UV-Vis spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), field emission scanni

12. Biological characteristics and probiotic effect of Leuconostoc lactis strain isolated from the intestine of black porgy fish
A strain of lactic acid bacteria, Leuconostoc lactis, was isolated from the intestinal tract of black porgy, Sparus macrocephalus, and identified by conventional biochemical characteristics and 16S rDNA gene sequence analysis. The isolated strain had the ability of bile tolerance and resistance to low pH, and survived well in the trypsinase and pepsin soluti
