15. Phytochemical Analysis, Multi-Element Composition and Biological Activities of Extracts and Lupenone from Albizia inundata (Mart.) Barneby & J.W.Grimes
In this study, antimicrobial activity of extracts and lupenone from A. inundata (Fabaceae, Mimosoideae), were tested. In addition, the multi-element composition of the leaves, bark and stems (heartwood) of A. inundata was evaluated using inductively coupled plasma optical emission spectrometry (ICP OES). Lupenone was isolated in the petroleum ether extract o

16. Can diabetes mellitus modify the plasma concentrations of rifampicin in patients under treatment for tuberculosis?
Abstract Rifampicin is a key component of treatment for tuberculosis and its efficacy is determined by the blood levels attained after therapeutic doses. However, there is a high variability of rifampicin blood levels that is related to both the patient and the formulation used. To date, the effect of diabetes mellitus on the plasma levels of rifampicin was

17. Simultaneous Quantification of Plasma Catecholamines and Metanephrines by LC-MS/MS
The quantification of the low levels of catecholamines and metanephrines in biological fluids is important for clinical screening of pheochromocytoma/paraganglioma and diagnosis of overtraining syndrome in athletes. We introduce a novel, accurate and sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for simultaneous quantification of

18. Quality pattern evaluation of frozen soursop pulps: an assessment based on chemical composition and chemometric analysis
Abstract In the present study, the physicochemical properties and mineral composition of commercially-frozen soursop pulps from the southern region of the state of Bahia, Brazil, were evaluated. The physicochemical parameters such as soluble solids (°Brix), acidity and pH were determined according to reference methodologies. For mineral composition evaluati

20. Chemometric Optimization of the Methodology for Determination of Molybdenum in Soils and Plants by Square Wave Adsorptive Stripping Voltammetry
The method is based on the adsorptive accumulation of complex molybdenum(VI) with 8-hydroxyquinoline, using voltammetric square wave cathodic stripping voltammetry. The composition and concentration of the supporting electrolyte, frequency (Hz), amplitude (mV) and deposition time (s), were optimized by factorial design in relation to current reduction of mol

21. Performance Parameters, Plasma Lipid Status, and Lymphoid Tissue Fatty Acid Profile of Broiler Chicks Fed Camelina Cake
ABSTRACT The effects of dietary camelina cake (CAMC) on broiler chicks’growth performance, plasma lipid status and fatty acid profile (FA) of lymphoid organs were evaluated. Six hundred broilers (3-week-old, Cobb 500) were randomly allotted for 20 days in a feeding trials into 2 groups: control (C; corn-soybean meal-canola meal basal diet) and experimental

22. Simultaneous determination of anti-diabetic drugs
A novel reverse phase, isocratic HPLC method is described to separate five anti-diabetic drugs i.e., glimepiride, metformin, sitagliptin, rosiglitazone and pioglitazone. Nucleosil C18 analytical column was used as stationary phase, while mobile phase consisted of acetonitrile:phosphate buffer: methanol (40/40/20, v/v) pH 2.0. Effluent was monitored at a flow
