Gadolinium

Motexafin gadolinium

Gd (157.9241)

Although gadolinium agents have proved useful for patients with renal impairment, in patients with severe renal failure requiring dialysis, there is a risk of a rare but serious illnesses, called nephrogenic systemic fibrosis (NSF) or nephrogenic fibrosing dermopathy, that has been linked to the use of four gadolinium-containing MRI contrast agents. The disease resembles scleromyxedema and to some extent scleroderma. It may occur months after contrast has been injected. Its association with gadolinium and not the carrier molecule is confirmed by its occurrence in from contrast materials in which gadolinium is carried by very different carrier molecules. Gadolinium is a chemical element with symbol Gd and atomic number 64. It is a silvery-white, malleable and ductile rare-earth metal. It is found in nature only in combined (salt) form. Gadolinium was first detected spectroscopically in 1880 by de Marignac who separated its oxide and is credited with its discovery. It is named for gadolinite, one of the minerals in which it was found, in turn named for chemist Johan Gadolin. The metal was isolated by Lecoq de Boisbaudran in 1886. Gadolinium as a phosphor is also used in other imaging. In X-ray systems, gadolinium is contained in the phosphor layer, suspended in a polymer matrix at the detector. Terbium-doped gadolinium oxysulfide (Gd2O2S: Tb) at the phosphor layer converts the X-rays released from the source into light. This material emits green light at 540 nm due to the presence of Tb3+, which is very useful for enhancing the imaging quality. The energy conversion of Gd is up to 20\\%, which means that one-fifth of the X-rays striking the phosphor layer can be converted into light photons. Gadolinium oxyorthosilicate (Gd2SiO5, GSO; usually doped by 0.1-1\\% of Ce) is a single crystal that is used as a scintillator in medical imaging such as positron emission tomography or for detecting neutrons. Gadolinium is a constituent in many minerals such as monazite and bastnasite, which are oxides. The metal is too reactive to exist naturally. Ironically, as noted above, the mineral gadolinite actually contains only traces of Gd. The abundance in the earth crust is about 6.2 mg/kg. The main mining areas are China, USA, Brazil, Sri Lanka, India and Australia with reserves expected to exceed one million tonnes. World production of pure gadolinium is about 400 tonnes per year. Gadolinium is a silvery-white malleable and ductile rare-earth metal. It crystallizes in hexagonal, close-packed 1- form at room temperature, but, when heated to temperatures above 1235 °C, it transforms into its 2- form, which has a body-centered cubic structure. Gadolinium is a strong reducing agent, which reduces oxides of several metals into their elements. Gadolinium is quite electropositive and reacts slowly with cold water and quite quickly with hot water to form gadolinium hydroxide: Gadolinium, also known as 64gd or gadolinio, is a member of the class of compounds known as homogeneous lanthanide compounds. Homogeneous lanthanide compounds are inorganic compounds containing only metal atoms, with the largest atom being a lanthanide atom. Gadolinium can be found in dill, red beetroot, romaine lettuce, and spinach, which makes gadolinium a potential biomarker for the consumption of these food products. Gadolinium is a chemical element with symbol Gd and atomic number 64. Gadolinium is a silvery-white, malleable, and ductile rare earth metal. It is found in nature only in oxidized form, and even when separated, it usually has impurities of the other rare earths. Gadolinium was discovered in 1880 by Jean Charles de Marignac, who detected its oxide by using spectroscopy. It is named after the mineral gadolinite, one of the minerals in which gadolinium is found, itself named for the chemist Johan Gadolin. Pure gadolinium was first isolated by the chemist Paul Emile Lecoq de Boisbaudran around 1886 .

Dimethyldithiophosphate

O,O-Dimethyl phosphorodithioate, sodium salt dihydrate

C2H7O2PS2 (157.9625)

Dimethyldithiophosphate, also known as O,O-dimethyldithiophosphate, O,O-dimethyl phosphorodithioate, copper (+1) salt or O,O-dimethyldithiophosphoric acid, is classified as a member of the phosphorodithioic acid O,O-diesters. Phosphorodithioic acid O,O-diesters are organooxygen compounds that contain a phosphorodithioic acid, which is O,O-disubstituted by an organyl group. Dimethyldithiophosphate is considered to be slightly soluble (in water) and acidic. (ChemoSummarizer)

Calcium acetate

C4H6CaO4 (157.9892)

It is used in foods as a firming agent, acidity regulator, sequestrant, stabiliser and thickener, and nutrient supplement (Ca source). It is used as an acidifier/preservative in bread, and in some gelling mixtures. Calcium acetate is a food additive, mainly in candy products.; Calclacite is a name for calcium acetate chloride pentahydrate, which is treated as mineral species but possess anthropogenic origin.; Patients with advanced renal insufficiency (creatinine clearance less than 30 ml/min) exhibit phosphate retention and some degree of hyperphosphatemia. The retention of phosphate plays a pivotal role in causing secondary hyperparathyroidism associated with osteodystrophy, and soft-tissue calcification. The mechanism by which phosphate retention leads to hyperparathyroidism is not clearly delineated. Therapeutic efforts directed toward the control of hyperphosphatemia include reduction in the dietary intake of phosphate, inhibition of absorption of phosphate in the intestine with phosphate binders, and removal of phosphate from the body by more efficient methods of dialysis. The rate of removal of phosphate by dietary manipulation or by dialysis is insufficient. Dialysis patients absorb 40\\% to 80\\% of dietary phosphorus. Therefore, the fraction of dietary phosphate absorbed from the diet needs to be reduced by using phosphate binders in most renal failure patients on maintenance dialysis. Calcium acetate when taken with meals combines with dietary phosphate to form insoluble calcium phosphate which is excreted in the feces. Maintenance of serum phosphorus below 6.0 mg/dl is generally considered as a clinically acceptable outcome of treatment with phosphate binders. Calcium acetate is highly soluble at neutral pH, making the calcium readily available for binding to phosphate in the proximal small intestine. It is used in foods as a firming agent, acidity regulator, sequestrant, stabiliser and thickener, and nutrient supplement (Ca source). It is used as an acidifier/preservative in bread, and in some gelling mixtures V - Various > V03 - All other therapeutic products > V03A - All other therapeutic products > V03AE - Drugs for treatment of hyperkalemia and hyperphosphatemia D064449 - Sequestering Agents > D002614 - Chelating Agents
