    Serum gastrin levels and colorectal neoplasia (1995)

    Notes: Abstract PURPOSE: Confirmation of an association between elevated serum gastrin concentrations and presence of colorectal tumors would have important implications with regard to screening procedures and therapeutic strategies. METHODS: We compared fasting serum gastrin concentrations of patients with colorectal cancer (n=91; mean age, 66 (range, 35–87) years), colorectal polyps (n=89; mean age, 61 (range, 38–86) years), or a normal colonoscopy (n = 101; mean age, 62 (range, 34–82) years) in the period between 1983 and 1992. RESULTS: Median serum gastrin concentrations were, respectively, 20, 20, and 21 pmol/liter (not significant). We were unable to find a relation with histology of the polyp, presence or severity of dysplasia, and extent of cancer. CONCLUSIONS: This large study fails to show any difference in serum gastrin concentrations among the three studied groups.

    Notes: Abstract To take into account the nonequilibrium between the temperatures (electronic, rotation, vibration, translation) in plasmas, the partition function are modified. Then they are used to determine the concentration in a Gibbs free energy minimization method adopted to a multi-temperature plasma. Their influence oil the results for different temperature hypotheses is quantified. The composition and thermodynamic properties of an Ar-H2 mixture are given and discussed for different temperature nonequilibria.
