0 pg/ml had significantly diminished survival compared with the patients whose serum DKK1 levels were lower (p = 0.033). The DKK1 overexpression in the cancer specimens significantly correlated with the increased serum DKK1
concentrations.\n\nConclusions: Serum DKK1 levels have the potential as a diagnostic marker at a low cutoff value and ass prognostic marker at a high cutoff find more value. Serum and tissue DKK1 levels may aid in diagnosing gastric cancer and predicting patient outcomes. (c) 2012 Elsevier B.V. All rights reserved.”
“The effect of protein concentration, in the range of 0-26 mg/mL for two Fc-fusion proteins, on the crystallinity and polymorphism of mannitol and sodium chloride in a lyophilized model formulation was examined. Mannitol hydrate levels were quantified based on moisture data LY3039478 concentration and correlated to the X-ray diffraction peak area. In all formulation conditions, sodium chloride did not crystallize in samples with >44% total amorphous content. As protein concentration
increased through the range of 1-5 mg/ML prior to lyophilization, beta-mannitol decreased in amount, becoming undetectable at protein concentrations above 5 mg/mL. Conversely, delta-mannitol increased as a function of protein concentration, reaching a maximum level at similar to 5 mg/mL protein. Above 10 mg/mL protein, mannitol crystallization was increasingly inhibited. Sucrose control vials showed higher levels of mannitol hydrate than either model protein. Both proteins behaved comparably with respect to mannitol crystallinity and polymorphism despite significant differences in molecular weight. Because of the differences between protein and sucrose control samples, protein concentration must be taken into consideration when assessing the lyophilization of mannitol containing solutions.

used large sequence polymorphisms to determine the genotypes of 397 isolates of Mycobacterium tuberculosis from human immunodeficiency virus-uninfected Vietnamese adults with pulmonary (n = 235) or meningeal (n = 162) tuberculosis. We compared the pretreatment radiographic appearances of pulmonary tuberculosis and the presentation, response to treatment, and outcome of tuberculous meningitis see more between the genotypes. Multivariate analysis identified variables independently associated with genotype and outcome. A higher proportion of adults with pulmonary tuberculosis caused by the Euro-American genotype had consolidation on chest X-ray than was the case with disease caused by other genotypes (P = 0.006). Multivariate analysis revealed that meningitis caused by the East Asian/Beijing genotype was independently associated with a shorter duration of illness before presentation and fewer cerebrospinal fluid (CSF) leukocytes.
