Livers of tungsten-treated rats have been shown to contain inactive protein which cross-reacts with antibody prepared against native rat liver sulfite oxidase. The cross-reacting material (CRM) was shown to be immunologically identical to the native enzyme by Ouchterlony double immunodiffusion. Difference spectrophotometry, acrylamide gel electrophoresis, and immunological analysis of the prote...

approved: Alan T. Bakalinsky Sulfite mutants representing five complementation groups, previously derived from an ethyl methanesulfonate-treated haploid strain of Saccharomyces cerevisiae were studied. Although the wildtype 5. cerevisiae strain used (isogenic to X2180-1 A) had a basal tolerance for sulfite (7 |iM free H2SO3), the sensitive and resistant mutants were found to tolerate less than ...

The purpose of the present study is evaluation of bonding durability of tri-n-butylborane (TBB) initiated resin without 4-methacryloyloxyethyl trimellitate anhydride (4-META) joined to human enamel. Ground human enamel was bonded with TBB resin under six surface conditions: 1) as ground, 2) primed with Teeth Primer, 3) sodium sulfite solution, 4) 4-META solution, 5) acetone-water, and 6) phosph...

Abstract Sulfite is a common food additive that prevents oxidation from damaging nutrients, and it has long been used in the industry as bleaching agent. It can harm human body if taken wrongly or excessively. In this study, three dyes (cresol red, chlorophenol bromocresol green) were explored to analyze presence of sodium sulfite (SS) an inexpensive, disposable paper sensor with lower visible ...

The market value of crustaceans depreciates during storage due to the appearance melanosis caused by polyphenol oxidases. Sulfite derivatives are used as melanosis-inhibiting agents, but their unhealthy effects make it preferable replace them with natural preservatives. In this work, a crude enzymatic extract from whiteleg shrimp (Penaeus vannamei) was characterized and test diphenol oxidase-in...

The deteriorating quality of the environment and consequently stricter emission limits force the produc­ ers of pollutants to modernize their current technolo­ gies, to reduce technologies with toxic materials or to v minimalize emissions. The industrial use of formaldehyde in various fields such as textile, wood, leather, and food process­ ing industry causes a major environmental problem. For...

Effects of respirable aerosols of sulfuric acid, ammonium sulfate, sodium sulfite, and ammonium persulfate on lungs of rats are reviewed. The literature regarding interactions between ozone or nitrogen dioxide and acidic aerosols (ammonium sulfate, sulfuric acid) is discussed. An unexpected interaction between nitrogen dioxide and sodium chloride aerosol is also discussed. An attempt is made to...
