Data for the intake of copper, zinc, and manganese in Japanese populations obtained by detailed diet assessment methods and the most recent version of the food composition database in Japan are scarce. Moreover, data on food sources which contribute to the intake of these nutrients in Asian countries, including Japan, are not available. Here, we estimated copper, zinc, and manganese intake and ...

The elucidation of the selective catalytic reduction mechanisms over state-of-the-art metal-promoted zeolites is essential for nitric oxides removal in automobile and stationary source applications. In this work, H/ZSM-5 catalysts modified with transition metals, including copper, manganese, nickel, were prepared by using an incipient wetness impregnation method evaluated ammonia. Results indic...

Although it has been proposed that trace minerals have anti-oxidative functions and are related to the control of blood pressure, only a limited number of studies directly address the issue. Thus, the purpose of our study was to assess the intake of copper and manganese, which are trace minerals, and to clarify their relation to blood pressure. In a cross-sectional study, the blood pressure of ...

Superoxide anion generation plays an important role in the development of paraquat toxicity. Although superoxide dismutase mimetics (SODm) have provided protection against organ injury involving generation of superoxide anions, they often suffer problems, e.g., regarding their bioavailability or potential pro-oxidant activity. The aim here was to investigate and compare the therapeutic potentia...

The preparation, characterization, and adsorption properties of Mn by manganese oxide coated zeolite (MOCZ) and its ability in removing Mn by adsorption were investigated. Characterization analyses were used to monitor the surface properties (and their changes) of the coated layer and metal adsorption sites on the surface of MOCZ. The adsorption experiments were carried out as a function of sol...

The prion protein (PrP) binds copper and has antioxidant activity enhancing the survival of neurones in culture. The ability of the PrP to bind other cations was tested and it was found that only manganese could substitute for copper. Although initially manganese-loaded PrP exhibited similar structure and activity to copper-loaded PrP, after aging, manganese-loaded PrP became proteinase resista...

To investigate the correlations among seminal plasma Magnesium (Mg), Phosphorus (P), Potassium (K), Calcium (Ca), Chromium (Cr), Manganese (Mn), Iron (Fe), Copper (Cu), Zinc (Zn), Selenium (Se), Molybdenum (Mo) and Iodine (I) concentrations and semen parameters [1– 15]. 500 fertile and 1000 infertile males provided a standardized semen specimen. Total Magnesium (Mg), Phosphorus (P), Potassium (...

This study reports on data obtained from a pilot survey focusing on house dust and toenail metal(loids) concentrations in residents living in the industrial city of Estarreja. The study design hereby described aims at investigating relationships between human toenails and both copper and manganese levels in settled house dusts. A total of 21 households and 30 individuals were recruited for the ...

Some pesticide chemicals are based on inorganic elements such as sulfur, copper (i.e. copper sulfate ‘Bordeaux mixture’, copper hydroxide, and copper oxychloride), and arsenic salts (i.e. lead arsenate, calcium arsenate, sodium arsenite), or they contain an inorganic element in their chemical structure such as the organometallic pesticides based on manganese dithiocarbamate (maneb), manganese a...

Waste metals in the form of metal oxide (hydroxide) sludges are generated in significant amounts by the metal finishing industries, and their accumulations pose problems for disposal and challenges for recycle. The availability of technically feasible efficient separations of metals such as nickel, cobalt, chromium, cadmium, copper, tin, zinc, lead, manganese, molybdenum, and titanium from plat...
