Hypouricemia, defined as a serum uric acid (UA) concentration < 120 µmol/L, is a rare laboratory finding with a prevalence of 0.21–0.53% that varies with age [1,2].Secondary hypouricemia may be caused by Fanconi syndrome, cystinosis, diabetes mellitus, and/or …
Very long-chain acyl-CoA dehydrogenase deficiency (VLCADD) is a rare genetic disorder of fatty acid metabolism that is transmitted in an autosomal recessive pattern. It occurs when an enzyme needed to break down certain very long-chain fatty acids is missing or not working properly.
Acid reflux symptoms can be typical or atypical in nature. Tingling limbs and nerve pain are considered rare and atypical acid reflux symptoms. Dr. Mark Babyatsky, a former department chairman at Mount Sinai School of Medicine in New York, explained that inflammation from acid reflux can reach the lungs and trigger pneumonia.
The individual rare-earth R 3+ complexes form rectangular bands with a minimum overlap of adjacent bands. The given rare-earth solution is collected, and the R 3+ ion is precipitated out of solution using oxalic acid. The rare-earth oxalate is converted to the oxide by heating it in air at 800–1,000 °C (1,472–1,832 °F). Solvent extraction
A strong acid is one which completely dissociates in its solvent. Under most definitions, the acid dissociates into a positively-charged hydrogen ion (proton) and a negatively-charged anion. The seven most common strong acids are hydrochloric acid, nitric acid, sulfuric acid, hydrobromic acid, hydroiodic acid, perchloric acid, and chloric acid.
In addition, plants accumulate fatty acids, the so called unusual or rare fatty acids, that are character-ized by structural variations such as number and arrangement of unsaturated bonds, chain branches, type of functional groups (hydroxyls, ketones, epoxyls, etc.), cyclic structures and halogenation. In
The third of the rare symptoms of acid reflux is more often related to a heart attack than to reflux. However, in many cases, chest pain is related to acidity. Even if it is not serious, in some cases the ideal is to look for a hospital or emergency room. 4. Bitter taste in the mouth.

Tartaric acid was used as the carboxylic acid and the earlier optimized conditions of 5% acid concentration, 90 °C temp and 1 h of leaching time was employed for this study. With respect to mineral acids, typically an increase in rare earth leaching is observed when pulp density is decreased.
Rare Amino Acids Support Impact Theory. For a decade, geologists and paleontologists have debated whether comet or meteorite impacts 65 million years ago wiped out a large fraction of existing species, including the last surviving dinosaurs. A rival theory holds that terrestrial processes such as volcanic eruptions caused the mass extinctions ...
The most common acids used as chemical separators in mining — nitric, sulfuric or phosphonic acids — also are able to extract rare-earth metals from coal ash but produce large amounts of acid waste, leaving the environment in worse shape than before.
The carborane superacids may be considered the world's strongest solo acid, as fluoroantimonic acid is actually a mixture of hydrofluoric acid and antimony pentafluoride. Carborane has a pH value of -18. Unlike fluorosulfuric acid and fluoroantimonic acid, the carborane acids are so noncorrosive that they may be handled with bare skin.
Other rare amino acid disorders include histidinemia, Hartnup disease, hyperlysinemia, formiminotransferase deficiency, 2 aminoadipic semialdehyde dehydrogenase (antiquin deficiency), prolidase deficiency, proline oxidase, deficiency, 5-oxoprolinase deficiency etc. will not be reviewed in this article and can be found in
In addition, plants accumulate fatty acids, the so called unusual or rare fatty acids, that are characterized by structural variations such as number and arrangement of unsaturated bonds, chain branches, type of functional groups (hydroxyls, ketones, epoxyls, etc.), cyclic structures and halogenation. In addition they are rare in reference to ...
Your baby's newborn screening may include testing for certain amino acid metabolism disorders. These are rare health conditions that affect a body's metabolism. Metabolism is the way your body changes food into the energy it needs to breathe, digest food …
The role of protein synthesis in rare genetic disease. Protein translation is the process by which cells translate the nucleic acid sequence of an RNA molecule to the amino acid sequence of a protein. The Antonellis lab studies the process by which impaired protein translation can cause diverse rare genetic diseases.
Next, researchers hope to test bio-acid on industrial PG and other wastes that are generated during phosphoric acid production and also contain rare-earth elements. "I think there's such a vast reserve there," Reed said. "At some point, push comes to shove and we're going to have to look at PG as a viable resource. ...

Neutralization between an acid and a base produces water plus a salt. Carboxylic acids in aqueous solution and liquid or molten carboxylic acids can react with active metals to form gaseous hydrogen and a metal salt. Such reactions occur in principle for solid carboxylic acids as well, but are slow if the solid acid remains dry.

Acid Mine Drainage (AMD) has been of environmental concern for decades but found to be a viable source of critical Elements (CEs), including Rare Earth Elements (REEs). The current AMD treatment methods typically use hydroxide base chemicals for neutralization which results in precipitation of ions from the solution.
