Kathon is a biocide consisting of a mixture of two isothiazolinone derivatives (5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4-isothiazolin-3-one) in an approximate ratio of 3:1, respectively, and with MgCl2 and Mg(NO3)2 present as stabilizers. The isothiazolinones are marketed under several brand names, and the concentration of the active ingredient(More)
The ability to identify the clinical nature of the recurrent duplication of chromosome 17q12 has been limited by its rarity and the diverse range of phenotypes associated with this genomic change. In order to further define the clinical features of affected patients, detailed clinical information was collected in the largest series to date (30 patients and(More)

Metyrapone, an inhibitor of cytochrome P-450-dependent monooxygenases, enhanced the induction of tyrosine aminotransferase by dexamethasone in primary cultures of hepatocytes, while it had no effect on the basal level of the enzyme activity in the absence of the hormone. The amplification of the hormonal induction of tyrosine aminotransferase activity was(More)
Dental laboratory technicians may be exposed to a number of toxic materials including metal alloys that have been identified as potential health hazards. Particularly, alloys, such as vitallium, wisil, duralium and vironite which in dentistry are used in the production of crowns, bridges and dental prostheses. The most common constituents of these(More)
