A new and sensitive method has been developed to analyze the molecular species of glycerophospholipids. This method was used to examine the effects of hypolipidemic intervention with n-3 fatty acids on the serum phosphatidylcholine species in severely hypertriglyceridemic patients. The drug treated group (n = 19) received 4 g/day of an 85% concentrate of the ethyl esters of eicosapentenoic and ...

objective: evaluating the effect of dentin conditioning with edta on microleakage of composite resin restorations, using two etch and rinse and two self-etch adhesives. materials and methods: one hundred and sixty extracted molars received class v cavity preparations right under the cej and were randomly divided into eight groups of 20, usingfour different adhesive systems. these adhesives incl...

We analyze three-body decays of and . Under the factorization approach, there are tree level diagrams for these decay modes and the transition matrix element of decay is factorized into a form factor multiplied by decay constant and form factor multiplied into weak vertices form factor. The transition matrix element of decay is also factorized into a form factor multiplied into weak vertic...

m.p. 118-121o. Yield, 6-6 g. A sample, after sublimation at 105°/0-2 mm., had m.p. 120-121'. (Found: C, 7241; H, 8 8%. C1oH1402 requires C, 72-3; H, 8.4%.) The above substance (12 g.), dissolved in 5N-NaOH (120 ml.), was shaken with benzoyl chloride (25 ml. at once, and 10 ml. after 20 hr.). After 24 hr. the precipitated solid was collected, well washed with water, and dissolved in ether. The e...

The present study demonstrated that an omega (n)-3 fatty acid, ethyl-eicosapentaenoic acid (ethyl-EPA), supplemented diet significantly attenuated the stress/anxiety behavior of rats in the "open field" and elevated plus maze, which was induced by subchronic intracerebroventricular administration of proinflammatory cytokine interleukin (IL)-1beta. Ethyl-EPA also reduced the rise in serum cortic...

This study measured the possible cross-reactivity of hapten-specific IgG antibodies purified from the sera of rabbits sensitized to an albumin-acetaldehyde conjugate [N-ethyl-rabbit serum albumin (N-ethyl-RSA)] with acetaldehyde-phosphatidylethanolamine adducts. The N-ethyl-RSA was coupled to an Affigel-10 column to affinity purify the IgG (anti-N-ethyl-RSA IgG). Dioleoyl-phosphatidylethanolami...

OBJECTIVE Patients undergoing hemodialysis are repeatedly exposed to stress and pain from approximately 300 punctures per year to their arteriovenous fistula. This study was designed to measure pain associated with venepuncture during AVF cannulation and to compare the effectiveness of ethyl chloride vapocoolant spray, topical eutectic mixture of local anesthetics (EMLA) cream and placebo in co...

BACKGROUND Rubbing moist skin results in higher frictional forces than rubbing very dry skin. As friction increases, the probability of activity-related blisters also increases. Therefore reducing moisture may reduce blister incidence during physical activity. OBJECTIVE We examined whether an antiperspirant can reduce foot blisters during hiking. METHODS In a double-blind study, cadets atte...

We report the preparation of a new class of copolymer films that consist of polymethylene (PM) with a low percentage ( approximately 1-4%) of randomly distributed ethyl ester side groups, consistent with poly(methylene-co-ethyl acetate). The films are prepared through a surface-catalyzed polymerization on gold surfaces upon exposure to a dilute solution of diazomethane (DM) and ethyl diazoaceta...

Skin is one of the main targets for reactive oxygen species; thus, reactive oxygen species-induced damage and protein and lipid modifications occur, and skin can undergo a wide array of diseases, from photosensitivity to cancer. In this study, human dermal fibroblasts exposed to hydrogen peroxide (0-1000 micromol/L) exhibited a marked increase in both protein carbonyls and 4-hydroxy-2-nonenal, ...
