question:
The C57BL/6J-Min/+ (Min/+) mouse bears a germline mutation in Apc and is therefore a model for familial adenomatous polyposis and sporadic colorectal cancer. Min/+ intestinal mucosa exhibits a marked tendency for spontaneous adenoma formation. Curcumin is a phenolic antioxidant known for its antitumor and immune modulatory functions in vitro. Curcumin prevents adenoma formation in Min/+ mice, through a mechanism that may be related to its immunomodulatory properties.', 'To study the relationship between intestinal immunity and curcumin-induced antitumor response, we used immunohistochemistry to characterize the effect of curcumin treatment on resident intestinal immune effector cells in Min/+ mice.
answer:
Is inhibition of intestinal tumors by curcumin associated with changes in the intestinal immune cell profile?

question:
The observed association between pioglitazone and bladder cancer could be causal or because of bias in the design of prior studies. We hypothesize that proteinuria testing may lead to detection bias if routine test results for proteinuria lead to a full urinalysis.', 'We reanalyzed patients with diabetes mellitus within Kaiser Permanente Northern California. Logistic and Cox regression adjusted for age, sex, race, and smoking were used to assess the association of proteinuria testing with pioglitazone use, subsequent full urinalysis, and diagnosis with bladder cancer.', 'Patients treated with pioglitazone were more likely than others with diabetes to undergo testing for proteinuria (p<0.001). The odds of positive tests for proteinuria were higher among pioglitazone-treated patients (OR=1.41, 95%CI 1.36-1.46). A positive proteinuria test was associated with increased odds of completing a urinalysis in the following 6months (OR=1.78, 95%CI 1.73-1.85). Negative and positive proteinuria test results were inversely (hazard ratio (HR) 0.63, 95%CI 0.52-0.75) and positively associated (HR 2.45, 95%CI 2.12-2.82) with bladder cancer risk, respectively. Adjustment for negative and positive proteinuria testing reduced the magnitude of association between pioglitazone and bladder cancer by only 5 to 10% (ever-exposed HR: from 1.06 to 1.01 and >4years exposure HR: from 1.38 to 1.28).
answer:
Is proteinuria testing among patients with diabetes mellitus associated with bladder cancer diagnosis : potential for unmeasured confounding in studies of pioglitazone and bladder cancer?

question:
Left ventricular (LV) torsion is an important parameter of LV performance and can be influenced by several factors. Aim of this investigation was to evaluate whether QRS prolongation in left bundle branch block (LBBB) may influence global LV twist and twisting/untwisting rate in chronic systolic heart failure (HF) patients.', "We prospectively evaluated 30 healthy subjects (control group) and 100 chronic HF patients with severely impaired LV systolic function (ejection fraction 35%). Patients were divided into three groups according to QRS duration: A: QRS < 120 ms (n 49), B: 120 QRS 150 ms (n 28) and C: QRS > 150 ms (n 23). Patients in groups B and C presented LBBB. All subjects underwent standard trans-thoracic echocardiography and two-dimensional speckle-tracking echocardiography evaluation. Categorical variables were compared by the chi-square or the Fisher's exact test. Continuous variables were compared using the ANOVA test. Correlations between variables were analysed with linear regression.", 'Control subjects presented higher torsion parameters, when compared with patients in any HF group. Among the three HF groups, no differences were detected in global twist (4.79 3.54, 3.8 3.0 and 4.15 3.14 degrees, respectively), twist rate max (44.81 25.03, 37.94 19.09 and 37.61 24.49 degrees s(-1), respectively) and untwist rate max (-36.31 30.89, -27.68 34.67 and -39.62 26.27 degrees s(-1), respectively) (P>0.05 for all). At linear regression analysis, there was no relation between QRS duration and any torsion parameter (P>0.05 for all).
answer:
Does qRS duration in left bundle branch block affect left ventricular twisting in chronic systolic heart failure?
