They are also known to affect serum levels of several cytokines including adipocytokines. But the association between these cytokines and treatment outcome has not been fully elucidated. We examined pretreatment serum levels of 14 cytokines among 190 patients who were treated with pegylated interferon-a-2b plus ribavirin for chronic HCV-1b infection with high viral load (=5 log IU/mL) and analyzed their contribution to treatment response. Plasminogen activator inhibitor-1 (PAI-1), vascular endothelial
growth factor, and 11 clinical factors showed significant association with SVR in univariate logistic regression analysis. Four significant factors in multivariate analysis; serum PAI-1 (odds ratio [OR] = 15.42), body mass index (OR = 4.56), rs8099917 (OR = 4.95) and fibrosis stage Autophagy inhibitor libraries (OR = 5.18) were identified as independent predictors. We constructed a simple and minimally invasive prediction score for SVR based on the presence of these factors except for fibrosis stage. The accuracy of this score was 73%, and was confirmed using an independent validation cohort NU7441 mw consisting of 31 patients (68%). The strongest correlation was between PAI-1 level and platelet count (r = 0.38, P = 1.8 x 10(-7)), and PAI-1 level
was inversely correlated with fibrosis stage. Serum PAI-1 is a novel predictor for the response to combination therapy against chronic HCV-1b infection and may be associated with liver fibrosis.”
“In the present
work, a new methodology to estimate the mean bubble size (dB) in pneumatic bioreactors is proposed. The semi-theoretical method is based on Higbie’s penetration theory and estimates dB. It uses experimental gas hold-up (epsilon) data and volumetric mass transfer coefficient (k(L)a) obtained VS-6063 mw in three scales of concentric-tube airlift reactor (ALR) of 2, 5 and 10 dm(3) and three different pneumatic bioreactors of 2 dm(3,) which are concentric-tube airlift reactor (ALR), bubble column reactor (BCR) and split airlift reactor (SAR). The parameter kLa was separated into its components k(L) and a. Mean bubble size (dB) and convective oxygen transfer coefficient (k(L)) proved not dependent on the superficial gas velocity in the riser (U(GR)) for ALR and SAR and superficial gas velocity (U(G)) for BCR reactor in the experimental range studied. The results indicate that k(L)a is a function only of the gas-liquid interfacial area of the bubbles (a) and therefore of the gas hold-up (epsilon). Published by Elsevier B.V.”
