Increasing applications of microwave radiation are of great concern with regard to public health. Several studies have been conducted detect effects of microwave exposure genetic material leading to negative or questionable results. The Micronucleus (MN) assay which is proved to be a useful method for detection of radiation exposure-induced cytogenetic damage was used in the present study to in...

background: benzene, toluene, ethylbenzene and xylene (btex) are the most important toxic volatile compounds in the air and could be easily absorbed through the respiratory tract. in recent years, the risk of exposure to btex compounds, especially benzene as a carcinogen, has been considered in petroleum depot stations. objective: to assess the occupational exposure of petroleum depot workers i...

In the mol-ecule of the title compound, C(9)H(12)O(9)S(3), the two methanesulfonate groups re located one above and one below the ring plane. The C-O-S angle range is 119.3 (2)-121.1 (2)°. This conformation is different from that of the benzene analog 1,2,5-tris-(p-toluene-sulfonate), which is a three-legged 'table' with all fragments of the p-toluene-sulfonate on top of the benzene ring. In th...

It has been reported (1) that cystine is metabolized by resting cells of Proteus vulgaris and Proteus morganii to pyruvate, ammonia, and hydrogen sulfide, Toluene-killed cells of P. morganii also carried out the reaction and to a lesser degree attacked homocysteine, yielding hydrogen sulfide, ammonia, and some unidentified product. Inasmuch as the use of toluene-killed cells may not obviate ent...

Engineering of the reaction medium and study of an expanded range of reaction temperatures were carried out in an effort to positively influence the outcome of Novozyme-435 (immobilized Lipase B from Candida antarctica) catalyzed epsilon-CL polymerizations. A series of solvents including acetonitrile, dioxane, tetrahydrofuran, chloroform, butyl ether, isopropyl ether, isooctane, and toluene (lo...
