Benzene is a human carcinogen and an ubiquitous environmental pollutant. Identification of specific and sensitive biological markers is critical for the definition of exposure to low benzene level and the evaluation of the health risk posed by this exposure. This investigation compared urinary trans,trans-muconic acid (t,t-MA), S-phenylmercapturic acid, and(More)
S-Phenylmercapturic acid (S-PMA), is a urinary metabolite of benzene, thought to be derived from the condensation product of benzene oxide with glutathione. S-PMA may be determined by GC, HPLC (UV or fluorescence detection), GC-MS, LC-MS/MS or immunoassays. The limit of sensitivities of most of these techniques is 1 microg/l urine or below. It has been(More)
We investigated via transesophageal echocardiography 29 patients with Duromedics mitral prosthesis to define the characteristics of normal and abnormal functioning valves as well as the advantages of this study compared to transthoracic echocardiography. The clinical and transthoracic examination identified three groups. The first group consisted of 8(More)
