C(72)-Macrocyclic systems functionalized with nitroaryl and arylamino groups were synthesized from the bisdioxine diacid dichloride 1,3,5,7-tetra-tert-butyl-2,6,9-trioxabicyclo[3.3.1]nona-3,7-diene-4,8-dicarbonyl dichloride (3).

To understand the role of ethylene in regulating the overall flavor of apple fruits, ethylene production or action was reduced using transgenic apple trees suppressed for ACC-synthase or ACC-oxidase enzyme activity or by the addition of 1-methylcyclopropene (1-MCP), an ethylene action inhibitor. Flavor components were differentially regulated in response to the suppression of both ethylene bios...

1. Oxalate crystals may occur in the CSF with ethylene glycol poisoning or primary hyperoxaluria type 1. Ethylene glycol is metabolized by alcohol dehydrogenase to form glycolic and oxalic acids. 2. Serum electrolytes and osmolality can be measured, and the anion and osmolar gaps can be calculated. Ethylene glycol poisoning is associated with an increased osmolar gap and increased anion gap met...

Laboratory experiments were conducted to unravel synthetic routes to form three C2H4O isomers—acetaldehyde (CH3CHO), ethylene oxide (c-C2H4O), and vinyl alcohol (CH2CHOH)—in extraterrestrial ices via electronic energy transfer processes initiated by electrons in the track of MeV ion trajectories. Here we present the results of electron irradiation on a 2:1 mixture of carbon dioxide (CO2) and et...

Ethylene glycol is one of the most common toxic alcohol ingestions requiring hemodialysis for treatment. With the FDA approval in 1997 of fomepizole (4-methylpyrazole), the indications for hemodialysis in addition to fomepizole for ethylene glycol poisoning have been examined in recent articles and case reports. Fomepizole, a competitive inhibitor of alcohol dehydrogenase, binds to the same sit...

Background and Aims Shoot elongation of arrowhead tubers (Sagittaria pygmaea Miq.) is stimulated by anoxia, ethylene and CO2. The aim of this study was to characterize anoxic elongation by comparison with elongation stimulated by ethylene and CO2. Methods The effects of the inhibitors aminoethoxyvinylglycine (AVG) as an ethylene biosynthesis inhibitor, 1-methylcyclopropene (1-MCP) as a potent i...
