Chromium Deficiency During Total Parenteral Nutrition
JAMA: The Journal of the American Medical Association, 1979Chromium is required for maintenance of normal glucose tolerance. After complete bowel resection and five months of total parenteral nutrition, severe glucose intolerance, weight loss, and a metabolic encephalopathylike confusional state developed in a patient. Serum chromium levels were at the lowest normal level. Supplementation of 150 μg of chromium

Determination of chromium(III) and total chromium in marine waters
Analytical and Bioanalytical Chemistry, 1996The development of an analytical technique is described which may be used to determine chromium, chromium(III) and chromium(VI) in estuarine and coastal waters. The method is based on selective micro-solvent extraction with subsequent GFAAS. The technique has been applied in a major North Sea estuary.

Chromium Content of Total Parenteral Nutrition Solutions
Journal of Parenteral and Enteral Nutrition, 1990Chromium (Cr) present as contaminant was analyzed by flameless atomic absorption spectrometry in a variety of commercially produced solutions and additives commonly used in total parenteral nutrition (TPN) formulas. Total Cr likely to be administered unintentionally per day was estimated both by summing the Cr in appropriate volumes of each solution ...

Isotope dilution measurement of inorganic chromium(III) and total chromium in seawater
Marine Chemistry, 1984Abstract A reproducible, low-blank, isotope-dilution technique for the determination of inorganic Cr(III) and total dissolved chromium in seawater has been developed. Analysis of coastal water from Brittany, France, confirms that inorganic Cr(III) exists in excess of the thermodynamic equilibrium value calculated from the model of Elderfield (1970 ...

Journal of Chromatographic Science, 2019
Chromium exists in its two stable oxidation states including trivalent chromium (Cr (III)) and hexavalent chromium (Cr (VI)) in natural waters. Chromium is an essential micronutrient in the trivalent form; however, the hexavalent form of chromium is ...

Chromium deficiency after long-term total parenteral nutrition
Digestive Diseases and Sciences, 1986A 63-year-old female developed unexplained hyperglycemia and glycosuria during administration of a total parenteral nutrition regimen on which she had been stable for several months. Because the patient had no history of diabetes or evidence of an infection, chromium deficiency was considered.

Dermatitis Associated With Chromium Following Total Knee Arthroplasty
The Journal of Arthroplasty, 2011All metal implants release metal ions because of corrosion. Although 20% to 25% of patients develop metal sensitivity after total joint arthroplasty, which is 10% higher than that in the general population, only very few highly susceptible patients exhibit symptoms.

Portland pozzolana cement in India with respect to total chromium and hexavalent chromium content
Advances in Cement Research, 2011The objective of the present research work was to evaluate total chromium and hexavalent chromium [Cr(VI)] in Portland cement in India especially for fly ash-based Portland pozzolana cement. Various additives have been used for the effective reduction of Cr(VI) in wet cement.

Developed were the determination methods of Cr(VI) and Cr(III) by electrospray ionization mass spectrometry, where HCrO(4)(-) (m/z 117) and [Cr(III)(cydta)](-) (m/z 394) were measured, respectively. Moreover, total Cr was also determined by measuring [Cr(III)(cydta)](-) after reduction of Cr(VI) with ascorbic acid.

Total diastereoselective synthesis of chromium cyclopropylcarbene complexes
Tetrahedron Letters, 1995Abstract Trans -substituted chromium cyclopropylmethoxycarbene complexes 4 have been obtained with total diastereoselectivity through a conjugated addition of in situ generated chloromethyllithium to vinylmethoxycarbene chromium complexes.
