Thallium may be measured in blood or urine as a diagnostic tool in clinical poisoning situations or to aid in the medicolegal investigation of suspicious deaths. Normal background blood and urine concentrations in healthy persons are usually less than 1 μg/litre, but they are often in the 1–10 mg/litre range (1,000–10,000 times higher) in ...
It is a rare blood condition in which the β-pyrrole ring of the hemoglobin molecule has the ability to bind irreversibly to any substance containing a sulfur atom. [ 1 ] [ 2 ] When hydrogen sulfide (H 2 S) (or sulfide ions ) and ferrous ions combine in the heme of hemoglobin, the blood is thus incapable of transporting oxygen to the tissues.
Copper toxicity (or Copperiedus) is a type of metal poisoning caused by an excess of copper in the body. Copperiedus could occur from consuming excess copper salts, but most commonly it is the result of the genetic condition Wilson's disease and Menke's disease, which are associated with mismanaged transport and storage of copper ions.
Indoxyl sulfate, also known as 3-indoxylsulfate and 3-indoxylsulfuric acid, is a metabolite of dietary L-tryptophan that acts as a cardiotoxin and uremic toxin. [1] [2] [3] High concentrations of indoxyl sulfate in blood plasma are known to be associated with the development and progression of chronic kidney disease and vascular disease in humans.
Here, arylsulfatase A hydrolyzes the sulfate group. [1] However, in order for this reaction to be carried out, a sphingolipid activator protein such as saposin B must be present. [2] Saposin B extracts sulfatide from the membrane, which makes it accessible to arylsulfatase A. [1] Arylsulfatase A can then hydrolyze the sulfate group.
Common side effects include low blood pressure, skin flushing, and low blood calcium. [1] Other side effects may include vomiting, muscle weakness, and decreased breathing. [4] While there is evidence that use during pregnancy may harm the baby, the benefits in certain conditions are greater than the risks. [5]
Mercury poisoning is a type of metal poisoning due to exposure to mercury. [3] Symptoms depend upon the type, dose, method, and duration of exposure. [3] [4] They may include muscle weakness, poor coordination, numbness in the hands and feet, skin rashes, anxiety, memory problems, trouble speaking, trouble hearing, or trouble seeing. [1]
Animals and humans naturally produce some hydrogen sulfide in their body; researchers have proposed that the gas is used to regulate metabolic activity and body temperature, which would explain the above findings. [18] Two recent studies cast doubt that the effect can be achieved in larger mammals.
