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...

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...

To identify the volatile flavor components in mustard paste (MP), compounds seven MPs available on market were isolated and analyzed by headspace solid-phase microextraction combined with gas chromatography–mass spectrometry. A total of 27 constituents found mass spectra retention index compared to data obtained from reference or related literature databases; these included nine esters, three s...

Total reduced sulfurs (TRS) include hydrogen sulfide (H2S), methyl mercaptan (methanethiol, CH3SH), dimethyl sulfide (CH3SCH3) and dimethyl disulfide (CH3S2CH3) and are referred to as noncondensible gases. They are part of a well-known environmental problem afflicting pulp mills exploiting the Kraft pulp mill process. These sulfur compounds are formed in the Kraft pulping process and come in co...

UNLABELLED On the basis of total temperature increase, normal dehydration, and maturity, the odor compositions of surface and internal piles in a well-run sewage sludge compost plant were analyzed using gas chromatography-mass spectrometry with a liquid nitrogen cooling system and a portable odor detector. Approximately 80 types of substances were detected, including 2 volatile inorganic compou...
