Toxic effects of nickel exposure on heart and liver of rats
(Toxic Substance Mechanisms, 1997-07-10) [Artigo]
The role of air pollution as a health risk factor is of special interest. Numerous toxic pollutants, such as nickel, are being released to the environment as a result of combustion of fossil fuels, crude oil, and coal. ...
Toxic mechanism of cadmium exposure on cardiac tissue
(Toxic Substance Mechanisms, 2000-12-01) [Artigo]
The presence of toxic substances in the workplace environment requires systematic evaluation of exposure and health status in exposed subjects. Cadmium is a highly toxic element found in water. Although free mediated ...
Iron determination by FAAS in fish feed and feces after ultrasound-assisted extraction
(Sensing and Instrumentation for Food Quality and Safety, 2009-01-01) [Artigo]
This paper proposes a method to determine iron in samples of fish feed and feces using ultrasound in the extraction of the analyte and in subsequent quantification by flame atomic absorption spectrometry. Using HCl 0.10 ...
Metal ions bound to the human milk immunoglobulin A: Metalloproteomic approach
(Food Chemistry, 2015-01-01) [Artigo]
The presence of calcium, iron, and zinc bound to human milk secretory IgA (sIgA) was investigated. The sIgA components were first separated by two-dimensional polyacrylamide gel electrophoresis and then identified by ...
Electron impact and chemical ionization mass spectral analyses of methyl esters species of free mycolic acid fraction from Rhodococcus lentifragmentus
(Chemistry and Physics of Lipids, 1996-09-30) [Artigo]
The free mycolic acid fraction from Rhodococcus lentifragmentus was derivatized to methyl esters and further fractionated into saturated (F-0), monounsaturated (F-1) and diunsaturated (F-2) species using argentation-TLC. ...
HIGH DIETARY CARBOHYDRATE AND PANCREATIC LESION
(Brazilian Journal of Medical and Biological Research, 1993-01-01) [Artigo]
The ability of high dietary carbohydrate to induce acute pancreatitis was investigated in groups of 16,2 1-day and 15-month old rats fed different carbohydrate diets for 30 days. Significantly increased levels of serum ...
Determination of the mercury fraction linked to protein of muscle and liver tissue of Tucunaré (Cichla spp.) from the Amazon Region of Brazil
(Archives Of Environmental Contamination And Toxicology, 2015) [Artigo]
This study used metalloproteomic techniques to characterize mercury (Hg)-bound proteins in the muscle and liver tissue of Tucunaré (Cichla spp.) collected at the Jirau Hydroelectric Power Plant in Madeira River Basin, ...
Cassava root husks as a sorbent material for the uptake and pre-concentration of cadmium(II) from aqueous media
(Orbital: the Electronic Journal of Chemistry, 2013) [Artigo]
Cassava husks were undergone to simple processes to obtain a fine powder whose particle diameter varied from 63 μm to 75 μm. The characterization of the material indicated the presence of the groups alcohol, amine and ...
