A low-volume automated injection system for the analysis of chemically complex, amino acid samples is presented. This system utilizes submicroliter sample volumes stored on a 75-mum inner diameter capillary. A pulse of positive pressure (82 kPa) is u

The determination of nitric oxide (NO) in human vitreous samples is complicated by the relatively short half-life of the analyte and the viscous, high salt and protein biological matrix. In this work, we developed a fast (< 5 min) and useful CE metho

We examined the effect of liver damage induced by carbon tetrachloride on the incidence of hepatic metastasis in the Greene hamster melanoma. Nine of 17 animals with liver damage had melanoma growth in the liver after the intraportal vein injection o
