BACKGROUND: Bioaccumulation of toxic metals in the population is associated with adverse health effects. Although some elements are essential for humans, high levels of exposure can be dangerous. OBJECTIVE: To describe the levels of Inorganic Arsenic (AsIn), Cadmium (Cd), Chromium (Cr), and Mercury (Hg) ...

Abstract Serum toxic metals have been implicated in development of many diseases. This study investigated the association between blood levels of lead and cadmium with abnormal bone mineral density (BMD) and incidence of osteoporosis. Sixty Saudi male adults age matching were assigned into two groups: A ...
Introducción. La exposición ambiental a plomo (Pb) aún constituye un problema de salud pública, particularmente para los niños. El estrés oxidativo podría representar un mecanismo primario asociado a su toxicidad. El objetivo del presente estudio fue determinar los niveles de Pb en sangre (Pb-S) e...
Introdução. O material particulado (MP) emitido pela queima de combustíveis fósseis de origem veicular é a principal fonte de exposição ambiental à elementos potencialmente tóxicos (EPTs) presentes no ar atmosférico dos centros urbanos, entre eles arsênio, níquel e chumbo. Objetivos. Este est...
This study goal to evaluate the effects of different concentrations of lead (Pb) and silver (Ag) on germination, initial growth and anatomical alterations of Lactuca sativa L. Plants use various mechanisms to reduce the impacts caused by anthropic action, such as xenobiotic elements of soils and water co...
The first report about antimicrobial resistance was published in the 1940s. And today, the antimicrobial resistance has become a worldwide problem. Because of this problem, there is a need to develop new drugs. That’s why we synthesized some novel thiazolidine-4-one derivatives and evaluated their anti...
Abstract The effects of Rheum ribes on lead acetate levels and hepatic biochemical factors due to lead acetate toxicity were investigated. Forty male Wistar rats were designated into four groups: Control; lead acetate (receiving in drinking water at 0.6 g/L, daily); hydroalcoholic extract groups (200 and...
Será o exame de tomografia computadorizada realmente de alto custo para o paciente, ou existe uma resistência por grande parte dos profissionais em indicá-lo? Paradigmas já foram quebrados com relação à dose de radiação. Ela é tão pequena que, em muitas universidades nos EUA, o paciente não u...
ABSTRACT BACKGROUND: There is limited research examining reasons causing refractory chronic constipation (RCC) in children. The effects of lead (Pb) and cadmium (Cd) exposures on this condition have been even less clear. However, some related factors may contribute to evaluation of blood lead levels (B...
This study evaluated influence of addition of lead foil coupled to different types of digital receptors on image noise and on diagnosis of fractured instruments in teeth without and with root filling. Twenty-six molars had their root canals (n=67) cleaned and shaped and were divided into groups with and ...
