Isocyanates are a leading cause of work-related asthma and workers in the auto-collision repair industry are at high risk for isocyanate exposures, particularly by the dermal route (Bello et al, 2007a and SHARP 2005). This project aims to extend and validate a rapid colorimetric surface wipe method, SWYPE™, for measuring isocyanate surface contamination in the workplace (Liu et al 2000 and 2005...

a simple, highly sensitive, accurate and selective method for determination of trace amounts of co(ii) in water samples is presented. isocyanate treated graphite oxides (igos) solid phase extraction adsorbent was synthesized by covalently isocyanate onto the surfaces of graphite oxides. the stability of a chemically (igos) especially in concentrated hydrochloric acid which was then used as a re...

the fruit of melia azedarach l. (meliaceae) was extracted with hexane, and its fatty acids methyl ester was analyzed using gc/ms. thirteen components representing 85.1% of the total extract were identified. the major components identified were methyl palmitate (18.8%), methyl linolenate (16.1%) and methyl linoleate (9.8%). the fruits’ extract had a lc50 of 5.5 ppm against the larvae of anophles...

was chemically bonded to poly-L-lysine and to bovine serum albumin (BSA) and showed a paramagnetic resonance spectrum that was sensitive to known structural changes in these molecules, such as those produced by changes in pH.2 This nitroxide-isocyanate is unfortunately not an ideal spin-labeling reagent since it is unstable and thus difficult to purify, and moreover the isocyanate group is rapi...

AIMS Because logistical and financial obstacles impede using large prospective cohort studies, surveillance decisions in occupational settings must often be made without evidence of relative benefits and costs. Using the example of isocyanate induced asthma, the most commonly reported immune mediated occupational asthma, the authors developed a model based approach to evaluate the costs and ben...
