Although soy foods have been consumed for more than 1000 y, it is only in the past 20 y that they have made inroads into Western diets. We investigated the effect of dietary supplementation with natto extracts produced from fermented soybeans on intimal thickening of arteries after vessel endothelial denudation. Natto extracts include nattokinase, a potent fibrinolytic enzyme having four times greater fibrinolytic activity than plasmin.
Due to the severe toxic effects of mercury (Hg) and its derivatives, they are strictly prohibited to be used as cosmetics ingredients. Nevertheless, unknown quantities of Hg are formulated in consumer cosmetic products. We demonstrate a disposable screen-printed electrode modified with 1,5-dibromopentane partially (7%) cross-linked poly(4-vinylpyridine) (SPE/pcPVP) system for the detection of hidden concentrations of mercury,
The potential effect of deploying mercury-contaminated fish-extracts for the manufacture of cosmetics and fishmeal, and discarding the ensuing waste material on municipal dumps was investigated. Our study showed that some levels in fishmeal were elevated and could exceed 600 Ð’Âµg/kg; while the concentrations in fish-oil (for cosmetics production) and fish-water (dumped) were appreciable and reached levels of 16 and 12 Ð’Âµg/kg,
Fair & Lovely is an over-the-counter skin-lightening cream sold widely in Saudi markets. Its mercury content is 0.304Ð’Â±0.316 ?g/g, in the range of 0.102 to 0.775 ?g/g. This study was designed to evaluate its toxic effects on mice. The cream was applied on mice for a period of 1 month at different intervals. Mercury levels were measured in the liver,
Introduction Sudden fever of unknown origin is quite a common emergency and may lead to hospitalization. A rise in body temperature can be caused by infectious diseases and by other types of medical condition. This case report is of a woman who had fever at night for several days and other clinical signs which were likely related to cracked dental mercury amalgam.
Woods et al. (2007) reported on exposure to dental amalgam fillings and urinary mercury excretion in children. They stated that Ð²Ð‚Ñšurinary mercury concentrations are widely used as a measure of mercury exposure from dental amalgam fillings.Ð²Ð‚Ñœ We would like to point out some caveats about interpreting the results of mercury in urine.

BACKGROUND: Urinary mercury concentrations are widely used as a measure of mercury exposure from dental amalgam fillings. No studies have evaluated the relationship of these measures in a longitudinal context in children.
OBJECTIVE: We evaluated urinary mercury in children 8-18 years of age in relation to number of amalgam surfaces and time since placement over a 7-year course of amalgam results.
The mercury (Hg) release from dental amalgam fillings increases by mechanical stimulation. The aim of this study was to investigate the possible impact of nocturnal bruxism on Hg exposure from dental amalgams and to evaluate the effect of an occlusal appliance. 88 female patients from an orofacial pain clinic with a complete maxillary and mandibular dentition,
Proximal tubular epithelial cells are major sites of homocysteine (Hcy) metabolism and are the primary sites for the accumulation and intoxication of inorganic mercury (Hg(2+)). Previous in vivo data from our laboratory have demonstrated that mercuric conjugates of Hcy are transported into these cells by unknown mechanisms. Recently, we established that the mercuric conjugate of cysteine [2-amino-3-(2-amino-2-carboxy-ethylsulfanylmercuricsulfanyl)propionic acid;
An assessment was conducted of the discharge from dental facilities of mercury in the form of amalgam to surface waters in the United States. Two pathways were examined Ð²Ð‚â€œ effluent from publicly owned results works (POTWs) and air emissions from sewage sludge incinerators (SSIs). The annual use of mercury in the form of amalgam in the U.S.
