Inflammatory bowel diseases (IBD) increase the risk of developing colorectal cancer. Dietary components that reduce inflammation are associated with lower cancer risk. The long-chain omega-3 fatty acid docosahexaenoic acid (DHA) is present in fish oil and has potent anti-inflammatory properties. The objective of this study is to determine whether dietary(More)
BACKGROUND Obesity increases the risk of colon cancer. It is also known that most colorectal cancers develop from adenomatous polyps. However, the effects of obesity and adipokines on colonic polyp formation are unknown. METHODS To determine if BMI, waist circumference or adipokines are associated with colon polyps in males, 126 asymptomatic men (48-65(More)
Diets high in fish and curcumin are associated with a decreased risk of CRC. Insulin resistance and obesity are associated with increased CRC risk and higher reoccurrence rates. We utilized cell culture to determine if dietary compounds could reduce insulin-induced cell proliferation comparing the response in normal and metastatic colon epithelial cells. We(More)
AIM To characterize the influence of diet-induced changes in body fat on colitis severity in SMAD3-/- mice. METHODS SMAD3-/- mice (6-8 wk of age) were randomly assigned to receive a calorie restricted (30% of control; CR), control (CON), or high fat (HF) diet for 20 wk and were gavaged with sterile broth or with Helicobacter hepaticus (H. hepaticus) to(More)
Hormones, growth factors and cytokines produced by adipocytes are associated with cancer progression. We suggest that chronically elevated adipokines as observed in the obese state may have profound effects locally on colon epithelial cells through growth promotion effects, induction of autocrine signaling, angiogenesis and immune cross-talk. This(More)
Chronic inflammation contributes to colorectal carcinogenesis. To determine whether serum cytokines are associated with colon polyps, 126 asymptomatic men (48-65 years) were recruited during colonoscopy. Serum cytokine concentrations were measured. Odds ratios were determined using polytomous logistic regression for polyp number and type. Men with serum(More)
AIM To identify and characterize drosophila mothers against decapentaplegic (SMAD)3-dependent changes in immune cell populations following infection with Helicobacter hepaticus (H. hepaticus). METHODS SMAD3(-/-) (n = 19) and colitis-resistant SMAD3(+/-) (n = 24) mice (8-10 wk of age) were infected with H. hepaticus and changes in immune cell populations(More)

BACKGROUND Dysregulated insulin signaling is thought to contribute to cancer risk. METHODS To determine if insulin-related serum factors are associated with colon polyps, 126 asymptomatic men (48-65 years) were recruited at colonoscopy. Blood was collected. Odds ratios were determined using polytomous logistic regression for polyp number and type. (More)
In this paper, we propose a strategy to build a measurement system that helps improve on-time performance in health care organizations. We analyze the measurement system for monitoring the performance of daily start times of first surgeries in a U.S. hospital. Although surgeons appear to be the main cause of delay, efforts to improve their on-time(More)
