Ether Lipid Metabolism Ether-linked glycerolipids are present in most mammalian tissues including brain, kidney, heart and skin. They were once strictly referred to as structural components of membranes, but by now it is known that some are biologically active (1). Ether lipids have as important roles as maintaining proper brain function, spermatogenesis, mediation of inflammation and lens orga...

Human glycol ether poisonings are sparsely reported in the medical literature. We describe a healthy 22-month-old boy who accidentally drank up to 330 mL of brake fluid containing a 75% bleed of various glycol ethers (5%-50% polyethylene glycol monomethyl ether, 15%-40% triethylene glycol monoethyl ether, 1%-30% triethylene glycol monomethyl ether, 1%-25% triethylene glycol monobutyl ether, 1%-...

Time-dependent ovulation-blocking effect of ether anesthesia was investigated using female Wistar-Imamichi rats showing a 4-day cycling rhythm. A 6-hr (1400-2000) and 8-hr (1400-2200) anesthesia with ether vapor on proestrus caused ovulation blockade in 85% and 100% of the rats, respectively. On the other hand, pentobarbital injections at 1400 and 1500 completely blocked the spontaneous ovulati...

The processing, mechanical and chemical properties of poly(ether ester)s, prepared from pivalolactone (PVL), 1,4-butanediol (4G) and dimethyl terephthalate (DMT), were studied. The poly(ether ester)s could easily be processed by injection moulding, owing to their favourable rheological and thermal properties. The tensile response of a poly(ether ester) with a butylene terephthalate (4GT) conten...

Objectives Ethanolamine ether phospholipids (ePE) and choline ether phospholipid (ePC) are present in human serum or plasma. Decreases in ether phospholipids (plasmalogens) in serum (plasma) have been reported in several diseases such as Alzheimer's disease, Parkinson's disease, metabolic syndrome, schizophrenia. Therefore, need for assay of ether phospholipids in plasma may increase in the fut...

Auxin physiologists often have attempted to establish correlations between the amount of auxin in a plant tissue and the manifestation of auxin activity such as growth, rooting, parthenocarpy, bud inhibition, etc. With Avena coleoptiles and tomato stem tips, to use specific examples, it is possible to demonstrate a correlation between growth and the amount of auxin which can be diffused from th...

Short-term exposure to diethyl ether strongly inhibits the metabolism of N-nitrosodimethylamine (NDMA). Twenty-six 6-week-old male Fischer 344 rats were exposed to ether vapor until their righting reflex was lost (approximately 2 min). The animals were removed from the ether and NDMA was immediately administered by i.v. bolus injection at a dose of 300 microgram/kg via a cannula surgically inse...
