Interactions of micronutrients can affect absorption and bioavailability of other nutrients by a number of mechanisms. In aqueous solutions, and at higher uptake levels, competition between elements with similar chemical characteristics and uptake process can take place. The consequences of these interactions may depend on the relative concentrations of the nutrients. In this work, we measure t...

Parkinson's disease and other neurological disorders are prevalent in Mongolia. Our previous studies revealed a significant correlation of these diseases with high oxidative stress due to a high body burden of harmful metals, such as manganese, iron, lead, cadmium, and aluminum. This report describes a 37-year-old male Mongolian patient with multiple sclerosis and essential micronutrient defici...

Biomining is the use of microorganisms to extract metals from sulfide and/or iron-containing ores and mineral concentrates. The iron and sulfide is microbially oxidized to produce ferric iron and sulfuric acid, and these chemicals convert the insoluble sulfides of metals such as copper, nickel and zinc to soluble metal sulfates that can be readily recovered from solution. Although gold is inert...

BACKGROUND Numerous studies attest to the role that inappropriate food product groups in the human diet, including children and adolescents diet, leading to abnormal intakes of many important nutrients, such as minerals. OBJECTIVES These studies were undertaken to assess the coverage of the recommended values for chosen minerals by 205 children and adolescents between the ages of 4 and 20 yea...

Iron, copper, zinc, and eight other minerals are classified as essential trace elements because they present in minute in vivo quantities and are essential for life. Because either excess or insufficient levels of trace elements can be detrimental to life (causing human diseases such as iron-deficiency anemia, hemochromatosis, Menkes syndrome and Wilson's disease), the endogenous levels of trac...

Minerals required in minute amounts by horses are specified as microminerals. These nutrients play an important role in a wide range of biochemical systems which affect virtually every metabolic function in the horse. With the exception of selenium, little attention has been given to microminerals in horse nutrition until shortly before the publication of the current NRC Nutrient Requirements o...

Diabetes is often associated with metabolic syndrome that is high blood pressure and abnormal lipid profile. Micronutrients mostly refer to vitamins and minerals. Micronutrients mainly exert their function as enzyme cofactors and transcription factors thus controlling the metabolic pathways. Metabolic syndrome is often characterized by various other clinical features like disturbance in glucose...

honey contains a wide variety of vitamins, minerals, amino acids and antioxidants. the vitamins found in honey include niacin, riboflavin and pantothenic acid; minerals present include calcium, copper, iron, magnesium, manganese, phosphorus, potassium and zinc. in addition honey contains a variety of flavonoids and phenolic acids which act as antioxidants, scavenging and eliminating free radica...

Due to the importance of clay minerals in metal sorption, many studies have attempted to derive mechanistic models that describe adsorption processes. These models often include several different types of adsorption sites, including permanent charge sites and silanol and aluminol functional groups on the edges of clay minerals. To provide a basis for development of adsorption models it is criti...
