ethanolamine/dental caries

The phenylethanolamine N-methyltransferase inhibition potency of non-aromatic ethanolamines is found by regression analysis to be significantly correlated with van der Waals volume, Vw. For the proper inhibition of this enzyme the size of a substituent on beta-carbon of ethanolamine chain should be

A nuclear magnetic resonance (NMR) spectroscopy and molecular modeling study of the interaction between alpha-cyclodextrin (alpha-CD) and phospholipids with serine, ethanolamine, or choline headgroups is presented. The experimental approach is based on 31P and 1H NMR measurements on small

Vascular malformations (VMs) are a wide vascular or lymphatic group of lesions common on the head and neck. The objective of this study was to assess the efficacy and morbidity of sclerotherapy for the treatment of VMs in the oral and perioral area. Special attention was given to factors that may

The CO2 adsorption properties of an organic macrocycle, cucurbit[6]uril (CB[6]), have been evaluated through experimental and theoretical studies. Quantum mechanical calculations show that CB[6] is capable of adsorbing the CO2 molecule selectively within its cavity relative to nitrogen. Adsorption

Sclerotherapy of esophageal varices is a procedure which caries high risk of DIC and ARDS syndrome induced by intravenous administration of obliterative agent. The aim of the study was to investigate hematological and arterial and venous gasometric parameters before and after injection of 5%

Extracellular phospholipase A2 was purified about 1.7 X 10(5) fold to near homogeneity from human synovial fluid of rheumatoid arthritis by sequential use of column chromatographies on heparin-Sepharose, butyl-Toyopearl, and reversed-phase HPLC. The final preparation showed a single band on

The structurally characterized flavohemoprotein from Alcaligenes eutrophus (FHP) contains a phospholipid-binding site with 1-16 : 0-2-cyclo-17 : 0-diacyl-glycerophospho-ethanolamine and 1-16 : 0-2-cyclo-17 : 0-diacyl-glycerophospho-glycerol as the major occupying compounds. The structure of the

1. Radioactive precursors of phospholipids, i.e., 32Pi, [1-14C]glycerol, [2-3H]glycerol, and [1-14C]acetate, were individually injected into the peritoneal cavity of mice bearing Ehrlich ascites tumor cells and the rates of incorporation were estimated. 2. Although [2-3H]glycerol was not practically

Macrophages obtained from the peritoneal cavity of rabbits were incubated with phosphate-(32)P in order to investigate the synthesis of phospholipid by these cells. After 6 hr of incubation 0.25% of the phosphate added to the medium had been incorporated into phospholipid by the macrophages, mainly

[1-14C]Glycerol was injected into the peritoneal cavity of mice bearing Ehrlich ascites tumor cells and the lipids were extracted from the cells after selected periods. 1-O-Alkyl-2-acyl-3-acetyl-glycerols and 1,2-diacyl-3-acetylglycerols were prepared from the ethanolamine and choline

[1-14C]Glycerol was injected into the peritoneal cavity of mice bearing Ehrlich ascites tumor cells and the lipids were extracted from the cells after selected periods. 1-O-Alkenyl-2-acyl-3-acetylglycerols were prepared from the ethanolamine phosphoglycerides and fractionated by AgNO3-impregnated

A trinuclear oximato complex, [(NiHL(1))(3)(μ(3)-O)]ClO(4) (1), with inverse metallacrown 9-MC-3 topology has been synthesized using a Schiff-base ligand (H(2)L(1)) formed by condensation of ethanolamine (Hea) and diacetylmonoxime (Hdamo). The diamagnetic compound has been characterized by

Thirteen different polypeptide subunits, each in one copy, five phosphatidyl ethanolamines and three phosphatidyl glycerols, two hemes A, three Cu ions, one Mg ion, and one Zn ion are detectable in the crystal structure of bovine heart cytochrome c oxidase in the fully oxidized form at 2.8 A

Arginine (0.8g/kg, ip) or a vehicle was administered to rats and the levels of arginine and a large number of related amino compounds++ were measured in plasma, heart, aorta, vena cava, pancreas and bronchi at specified time intervals. Arginine levels (nmol/ml) increased in the plasma from 237 to

The design and development of multifunctional carriers for drug delivery based on hollow nanoparticles (HNPs) have attracted intense interests. Ordinary spherical HNPs are demonstrated to be promising candidates. However, the application of HNPs with special morphologies has rarely been reported.
