Design of pyrazolo-pyrrolo-pyrazines and pyrazolo-pyrrolo-diazepines via AuCl3-catalyzed and NaH-supported cyclization of N -propargyl pyrazoles
(American Chemical Society, 2015)
A concise synthetic methodology for new heterocyclic scaffolds, such as pyrazolo-pyrrolo-pyrazine and pyrazolo-pyrrolo-diazepine skeletons, was developed. The key features of this method include (i) synthesis of pyrrole-derived ...
Synthesis, spectral characterisation and thermal behaviours of some new p-tert-butylcalix[4]arene and calix[4]arene-esters containing acryloyl groups
(2013)
The mono-, di-, tri-, and tetra-acryloyl esters of p-tert-butylcalix [4]arene and calix[4]arene were synthesised by reacting acryloyl chloride with sodium salts of p-tert-butylcalix[4]arene and calix[4]arene in THF. The ...
Comparação de tramadol e lornoxicam em anestesia regional por via intravenosa, um estudo randomizado e controlado
(Elsevier Editora Ltda, 2016)
Justificativa e objetivos A dor relacionada ao torniquete é um dos maiores obstáculos para a anestesia regional intravenosa (ARIV). Nosso objetivo foi comparar tramadol e lornoxicam usados em ARIV em relação aos seus efeitos ...
Tourniquet-inducedischaemia-reperfusioninjury: the comparison of antioxidative effects of small-dose propofoland ketamine
(Elsevier Editora Ltda, 2017)
Objectives The aim of the present study was to investigate the preventive effects of propofol and ketamine as small dose sedation during spinal anesthesia on tourniquet‐induced ischemia‐reperfusion injury.

Unenhanced 3D turbo spin echo MR angiography of lower extremity arteries: comparison with 128-MDCT angiography
(Springer-Verlag Italia s.r.l., 2016)
Purpose: This study aimed to investigate the feasibility and diagnostic power of unenhanced 3D turbo spin echo MR angiography sequence (a technique based on subtraction of corresponding images acquired in diastole and ...
Frequency and voltage dependence of electric and dielectric properties of Au/TiO2/n-4H-SiC (metal-insulator-semiconductor) type Schottky barrier diodes
(Institute of Physics Publishing, 2015)
The main electrical and dielectric properties of Au/TiO2/n-4H-SiC (MIS) type Schottky barrier diodes (SBDs) have been investigated as functions of frequency and applied bias voltage. We believe that the use of high dielectric ...
Synthesis, characterization of poly-2- (2-hydroxybenzylideneamino)-6- phenyl-4,5,6, 7-tetrahydrobenzo[b]thiophene-3-carbonitrile: Investigation of antibacterial activity and optical properties
(2012)
The oxidative polycondensation reaction conditions of 2-(2- hydroxybenzylideneamino)-6-phenyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3- carbonitrile were examined. The magnitude of the reflectance of the polymer decreases ...
Benzotriazole and benzothiadiazole containing conjugated copolymers for organic solar cell applications
(Elsevier Ltd, 2012)
2-Dodecyl benzotriazole (BTz) and benzothiadiazole (BTd) containing copolymers poly(4-(2-dodecyl-2H-benzo[d][1,2,3]triazol-4-yl)benzo[c][1,2,5] thiadiazole (P1), poly(4-(5-(2-dodecyl-7-(thiophen-2yl)-2H-benzo[d][1,2,3] ...
Boric acid: A simple molecule of physiologic, therapeutic and prebiotic significance
(Walter de Gruyter GmbH, 2015)
Boric acid, H3BO3, is a weak acid and at physiological pH is in the form of an uncharged small molecule. Behaving as a Lewis acid, it forms complexes with amino- and hydroxy acids, carbohydrates, nucleotides and vitamins ...
CO2 gas detection properties of a TIO2/Al2O3 heterostructure under UV light irradiation
(Institute of Physics Publishing, 2015)
Al/TiO2/p-Si and Al/TIO2/Al2O3/p-Si samples were prepared using the atomic layer deposition method (ALD) and their gas sensing properties were investigated. The electrical properties of the samples were studied using a two ...
