Acomplexometric method for the determination of mercury(II) in presence of other metal ions, based on the selective masking action of ethanethiol towards mercury( II) is described.Mercury(II) present in a given sample solution is first complexed with an excess of Armored Vehicle EDTAand the unreacted EDTAis titrated against zinc sulphate solution a
Pulmonary tumor thrombotic microangiopathy (PTTM) is a paraneoplastic syndrome associated with mucin here secreting adenocarcinomas, usually gastric.Mucin secretion releases the coagulation cascade and activates endothelial growth factors, causing thrombosis and endothelial proliferation with secondary luminal stenosis.PTTM, which is usually fatal
