This study investigates the potential beneficial effects of niacin (NA; vitamin B3) supplementation in rats chronically exposed to methylmercury (MeHg). Animals were randomly assigned one 4 groups (n = 6): Group I, control, received distilled water by gavage; II, MeHg (100 µg/kg/d) III, NA (50 mg/kg/d) drinking water; IV, gavage + water. Biochemical parameters levels glucose, triglycerides, total cholesterol and fractions, enzyme activities aspartate transaminase (AST) alanine (ALT)...
Methylmercury, organic form of mercury, can increase the number abnormal sperm and decrease concentration testosterone levels possibly due to damage caused by reactive species germ Leydig cells. Maná-cubiu (Solanum sessiliflorum Dunal) is a native fruit from Amazon rich in iron, zinc, niacin, pectin, citric acid, used foods, beverages, medicinal purposes, since it has been useful for treatment various diseases oxidative stress or nutritional deficiency. Therefore, this study evaluated...
Humans and animals can be exposed to different chemical forms of mercury (Hg) in the environment. For example, methylmercury (MeHg)-contaminated fish is part basic diet riparian population Brazilian Amazon Basin, which leads high total blood plasma Hg levels people living therein. induces toxic effects mainly through oxidative stress. Different compounds have been used prevent damage caused by MeHg-induced reactive oxygen species (ROS). This study aims investigate vivo sub-chronic exposure...
Results are presented as means ± standard deviations (SD) obtained from three replicated analyses (n = 3).
Incubation of guanosine and Sudan III induces the formation a stable adduct, which may be identified using spectrophotometric technique mass spectroscopy. The high nucleophilicity C8 position its proximity to N7 makes site susceptible nucleophilic attack, explains SN2 reaction detected between dye. In addition, direct interaction with calf thymus DNA was monitored simple technique. results presented indicate that modification chemical structure I (monoazo dye) (diazo markedly alters...
