The relationship between broiler breast meat color and pH, moisture content, water-holding capacity (WHC), and emulsification capacity (EC) was investigated. In each of three replicate trials, fillets were collected from three different commercial processing plants according to breast meat lightness (L*) values as follows: lighter than normal (light, L* > 53), normal (48 < L* < 53), and darker than normal (dark, L* < 46). Color values of lightness (L*), redness (a*), and yellowness (b*) were measured at 0 and 24 h after collection. Fillets were then ground and homogenized prior to determining color, pH, moisture, WHC, and EC of the ground meat. There was a significant difference among the three color groups (light, normal, and dark) in L*, a*, pH, WHC, and EC. The L* values of whole raw breast fillets had significant negative correlation coefficients with ground meat EC (-0.9237), pH (-0.9610), and a* (-0.6540). Emulsification capacity had significant positive correlations with pH (0.9572) and water-holding capacity (0.7080). WHC had significant correlations with a* (0.8143), moisture (-0.7647), and pH (0.7963). Lighter-than-normal meat was associated with low pH, high moisture, low EC, and low WHC. These results indicate that wide differences in raw breast meat color exist and that these differences may be used by poultry further processors as an indicator of fillets with altered functional properties.

Early mortality in SSc is substantial, and prevalent cohorts underestimate mortality in SSc by failing to capture early deaths, particularly in men and those with diffuse disease.

Objective. To examine the relationship between changes in anti-double-stranded DNA (anti-dsDNA) antibody levels and the risk of renal flare in patients with systemic lupus erythematosus (SLE), using data from 2 randomized, controlled trials.Methods. Analyses were based on 487 patients with SLE and a history of lupus nephritis who had an anti-dsDNA antibody titer >15 IU/ml at baseline, as measured by Farr assay. Results are presented for the combined population of patients, the placebo arms, and the drug treatment arms in which a dsDNA-based bioconjugate (abetimus sodium; LJP 394) was used.Results. Changes in anti-dsDNA antibody levels were inversely correlated with changes in the C3 level (P < 0.0001 in both trials). Cox proportional hazards regression models showed that changes in anti-dsDNA antibody levels correlated with the risk of renal flare. The models predicted that a point estimate of a 50% reduction in anti-dsDNA antibody levels is associated with a 52% reduction (95% confidence interval [95% CI] 26-68%, nominal P ‫؍‬ 0.0007) and a 53% reduction (95% CI 33-69%, nominal P < 0.0001) in the risk of renal flare in the 2 trials, respectively. In the 2 trials, the incidence of renal flare was lower in patients with sustained reductions in anti-dsDNA antibodies (3.0% and 4.1%, respectively) than in patients with stable or increasing antibody levels (21.3% and 20.3%, respectively).Conclusion. Changes in anti-dsDNA antibody levels were directly correlated with the risk of renal flare and inversely correlated with changes in the C3 level. Reducing anti-dsDNA antibody levels may represent a therapeutic objective in SLE patients with lupus nephritis, because it is associated with a reduced risk of renal flare.Anti-double-stranded DNA (anti-dsDNA) antibodies are diagnostic for systemic lupus erythematosus (SLE) (1) and have been implicated in the underlying pathogenesis of SLE renal disease and other disease manifestations (2-7).

BACKGROUND. Clonal cytogenetic abnormalities (CCA) were detected in Philadelphia chromosome (Ph)‐negative cells in some patients with chronic myeloid leukemia (CML) who attained a cytogenetic response to imatinib mesylate. In some patients, CCA/Ph‐negative status was associated with myelodysplasia or acute myeloid leukemia. The objective of the current study was to determine the prognostic impact of CCA/Ph‐negative cells. METHODS. The authors compared the pretherapeutic risk factors (Kruskall‐Wallis test), exposure to cytotoxic drugs (chi‐square test), and overall and progression‐free survival (Kaplan‐Meyer and logistic regression analysis, respectively) of 515 patients with mostly chronic‐phase CML who were treated with imatinib mesylate after failure of interferon‐α according to whether they attained a major cytogenetic response (MCR) (n = 324 patients), an MCR with CCA/Ph‐negative status (n = 30 patients), or no MCR (n = 161 patients). RESULTS. CCA/Ph‐negative status most frequently involved chromosomes Y, 8, and 7. No significant differences in pretherapeutic risk factors were detected between patients who attained an MCR with and without CCA/Ph‐negative cells, except that exposure to alkylating agents was more frequent in patients with CCA/Ph‐negative cells, and overall and progression‐free survival were identical. With a median follow‐up of 51 months, only 2 patients developed myelodysplastic syndromes (MDS). CONCLUSIONS. The overall prognosis for patients who had CML with CCA/Ph‐negative status was good and was driven by the CML response to imatinib mesylate. Isolated CCA/Ph‐negative cells in the absence of morphologic evidence of MDS do not justify a change in therapy. Cancer 2007. © 2007 American Cancer Society.
