Industrial and culinary practice effects on biologically active polyamines level in turkey meat
2021
Polyamines, including putrescine, spermidine, and spermine, are biological compounds present in nearly all food items. Their desirable physiological effects include cell division and growth. Hence, are undesirable in the diet of patients with tumor. This study aimed to assess the impact of curing agents (sodium chloride (0–2 g), sodium nitrite (0–200 ppm), sodium polyphosphate (0–0.5 g), and ascorbic acid (0–500 ppm)), cooking (frying (180°C), and boiling (100°C)) on polyamine contents in turkey breast meat using response surface methodology based on central composite design and dispersive liquid-liquid microextraction. Postprocessing changes were investigated using a high-performance liqui…

Pre-clinical assessment of a water-in-fluorocarbon emulsion for the treatment of pulmonary vascular diseases
2019
Abstract Hypoxic pulmonary vasoconstriction (HPV) is a well-characterized vascular response to low oxygen pressures and is involved in life-threatening conditions such as high-altitude pulmonary edema (HAPE) and pulmonary arterial hypertension (PAH). While the efficacy of oral therapies can be affected by drug metabolism, or dose-limiting systemic toxicity, inhaled treatment via pressured metered dose inhalers (pMDI) may be an effective, nontoxic, practical alternative. We hypothesized that a stable water-in-perfluorooctyl bromide (PFOB) emulsion that provides solubility in common pMDI propellants, engineered for intrapulmonary delivery of pulmonary vasodilators, reverses HPV during acute h…
Pyrazolobenzotriazinones Derivatives as COX Inhibitors: Synthesis Biological Activity and Molecular Modeling Studies
2010
Pyrazolylbenzotriazinones are endowed with structural analogy with the COX-2 selective inhibitor celecoxib. Considering that our research group has long been interested in the 3-pyrazolyl-substituted benzotriazinones as anti-inflammatory agents, six new pyrazolylbenzotriazinone derivatives 16a-c and 18a-c have been prepared by reacting the opportune ethyl 5-(2-aminobenzamido)-1-(pyridin-2-yl)-1H-pyrazole-4-carboxylate or 5-(2-aminobenzamido)-1-(pyridin-2-yl)-1H-pyrazole-4-carboxyic acid with sodium nitrite in glacial acetic acid. The biological studies revealed a good pharmacological profile for some pyrazolylbenzotriazinones and, in the case of the ethyl 5-(4-oxo-1,2,3-benzotriazin-3(4H)-y…
Importance of Sodium Nitrate in the Maturation Process of Gouda Cheese
2011
The aim of this study was to observe the dynamics of sodium nitrate during ripening, in was introduced in different amounts in the recipe. Sodium nitrate is the chemical compound also known as Chile saltpeter or Peru saltpeter, is used as an ingredient as a food preservative. Sodium nitrate should not be confused with the related compound, sodium nitrite. Sodium nitrate in the cheese gives a longer time of preservation (Moore J.C., 2010).
Role of sodium nitrite on phospholipid composition of cooked cured ham. Relation to its flavor
1997
Abstract The role of sodium nitrite on phospholipid composition was studied during the processing of cooked cured ham. Evolution of the different classes of phospholipids in raw meat, cured meat with brine injected at 0, 50 and 100 mg of sodium nitrite/kg meat, and cooked meat, was determined as well as fatty acid content of phosphatidyl choline and phosphatidyl ethanolamine in raw and cooked meat. The major effect of sodium nitrite was observed on phosphatidyl ethanolamine whose content was significantly lowered in the presence of this salt. This effect was observed at the end of the curing process and was not modified by the cooking. The fatty acid content between raw meat and cooked cure…
Electrochemical reduction of the nitrite to ammonium ions in presence of [MoO2(O2CC(S)C6H5)2]2−
1995
Abstract Ammonia is formed during potentiostatic reduction of sodium nitrite solutions on the nafion-complex-coated electrode. When (NH4)2[MoO2(O2CC(S)(C6H5)2)2] is present in NaNO2 solutions a polarographic wave is associated to electrocatalytic reduction of nitrite ion. The wave height varies linearly on the concentration of nitrite ion, allowing a procedure for analysing this ion. This electrochemical behaviour distinguishes the nitrite from the nitrate ions. The Mo(VI), Mo(V), and Mo(IV) are involved in catalytic redox processes determining formation of NH4+ from nitrite ions.
