Endocrinology. Molybdenum deficiency refers to the clinical consequences of inadequate intake of molybdenum in the diet. The amount of molybdenum required is relatively small, and molybdenum deficiency usually does not occur in natural settings. [1] However, it can occur in individuals receiving parenteral nutrition. [2][3]
Although human toxicity data is unavailable, animal studies have shown that chronic ingestion of more than 10 mg/day of molybdenum can cause diarrhea, growth retardation, infertility, low birth weight, and gout; it can also affect the lungs, kidneys, and liver. [98] [99] Sodium tungstate is a competitive inhibitor of molybdenum. Dietary ...
Molybdenum cofactor deficiency is a rare human disease in which the absence of molybdopterin – and consequently its molybdenum complex, commonly called molybdenum cofactor – leads to accumulation of toxic levels of sulphite and neurological damage. Usually this leads to death within months of birth, due to the lack of active sulfite oxidase.
Megavitamin-B6 syndrome, also known as hypervitaminosis B6, vitamin B6 toxicity, and vitamin B6 excess, [a] is a medical condition characterized by adverse effects resulting from excessive intake of vitamin B 6. [1][2][22] Primarily affecting the nervous system, this syndrome manifests through symptoms such as peripheral sensory neuropathy ...
Molybdenum prevents plasma proteins from binding to copper, and it also increases the amount of copper that is excreted in urine. Ruminants that consume high levels of molybdenum suffer from diarrhea, stunted growth, anemia, and achromotrichia (loss of fur pigment). These symptoms can be alleviated by copper supplements, either dietary or ...
Menkes disease. Menkes disease (MNK), also known as Menkes syndrome, [ 1 ][ 2 ] is an X-linked recessive disorder caused by mutations in genes coding for the copper-transport protein ATP7A, [ 3 ] leading to copper deficiency. [ 4 ][ 5 ] Characteristic findings include kinky hair, growth failure, and nervous system deterioration.
The river water was contaminated with toxic metals including arsenic, copper, barium, cadmium, chromium, lead, mercury, nickel, and thallium. [ 2 ] Cleanup costs may exceed $1.2 billion. [ 3 ] A toxic heavy metal is a common but misleading term for a metal noted for its potential toxicity. [ 4 ] Not all heavy metals are toxic and some toxic ...
Mineral deficiency. Specialty. Endocrinology. Mineral deficiency is a lack of the dietary minerals, the micronutrients that are needed for an organism's proper health. [1] The cause may be a poor diet, impaired uptake of the minerals that are consumed, or a dysfunction in the organism's use of the mineral after it is absorbed.
