AIMS To assess the risk profile for the failure of trabeculectomies in a large group of patients who were selected to be operated on without the use of antimetabolites. This was done in an effort to find subgroups of patients who may not need antimetabolites for primary procedures. METHODS Consecutive patients scheduled for routine trabeculectomies were operated during a 4 year period and wer...

We evaluated the effect of 19 hepatotoxicants and 20 antimetabolites on the expression of genes of the human nuclear receptor (NR) superfamily in human primary hepatocytes, utilizing NR superfamily-related data extracted from the toxicogenomics database Open TG-GATES. A considerable number of the drugs alone induced a significant fold change in the expression of a large number of NRs. The membe...

When 3acetylpyridine (3-AP) is fed to dogs, large amounts of a normal end-product of nicotinic acid metabolism, N’-methylnicotinamide (NMeN), appear in the urine (1). This finding might be interpreted as evidence that 3-AP, acting as an antivitamin, displaces nicotinamide from its nucleotides or prevents its incorporation therein, or, alternatively, that 3-AP is biologically oxidized to nicotin...
