Diallyl sulfide (DAS), a selective inhibitor of CYP2E1, has shown protective effects against alcohol- and acetaminophen-induced hepatotoxicity in many studies. However, DAS is also a CYP2E1 substrate that on metabolism produces toxic metabolites and causes cytotoxicity. The objective of this study was to find a potent DAS analog as a CYP2E1 inhibitor and has the characteristic of producing less...

The possible protective effect of a feed additive (Mycofix) against the toxic effects of 4,15-diacetoxiscirpenol (DAS) in growing broiler chickens was investigated in a 21-d fully randomized trial consisting of seven dietary treatments (control with no DAS or Mycofix added, 1 ppm DAS alone, 1 ppm DAS supplemented with 0.75 g/kg Mycofix, 1 ppm DAS supplemented with 1.5 g/kg Mycofix, 2 ppm DAS al...

OBJECTIVES The 28-joint disease activity score (DAS-28) guides the use of biologics in RA. The aims of this study were to investigate agreement between the ESR- and CRP-based DAS-28 definitions, and to examine how this agreement may be improved. METHODS Data were obtained from registers of early (n = 520) and established RA (n = 364) patients. Agreement over disease activity levels (remission...
