Accepted methods to evaluate intestinal vascularity intraoperatively include standard clinical criteria (SCC), doppler ultrasound (DUS), and intravenous fluorescein (FLF). A combination of methods is often used to overcome disadvantages of individual techniques. Assessment of intestinal vascularity by FLF was compared to SCC, DUS, and pulse oximetry (POX)(More)
Eighty-three patients with 117 episodes of candidemia were reviewed to examine the clinically significant variables and the results of treatment for this problem. Mortality was 52%. Patients who had bacteremia either synchronously or metachronously in association with Candida species had poorer survival rates. Staphylococcal and enterococcal species were(More)
A polyglycolic acid device has been designed for the performance of sutureless colonic anastomoses. The use of this biofragmentable anastomosis ring (BAR) was compared with conventional techniques in a prospective, randomized study of 59 patients (x age, 49 years) undergoing ileocolostomy (n = 23) or colocolostomy (n = 36). The anastomotic technique was(More)
Hyaluronan (formerly hyaluronic acid) is an important constituent of the interstitial matrix in skin. Following major burn injury in animal models, plasma hyaluronan can increase to levels 10-fold greater than normal. The present experiments were designed to determine whether this is a result of the increased lymph flow (QL) accompanying the injury or of an(More)
Breast Cancer Metastasis Suppressor 1 (BRMS1) suppresses metastasis of human breast cancer, ovarian cancer and melanoma in athymic mice. Studies have also shown that BRMS1 is significantly downregulated in some breast tumors, especially in metastatic disease. However, the mechanisms which regulate BRMS1 expression are currently unknown. Upon examination of(More)
BACKGROUND/PURPOSE Hypothermia (HT) remains a significant stress to the newborn and has been implicated in the pathogenesis of necrotizing enterocolitis (NEC). The authors assessed the effect of transient HT (32 degrees C) on regional organ blood flow in anesthetized piglets at age 7 to 10 days preterm (PREM), 1 to 2 days (NB), and 1 to 2 weeks (NEO).

African-American (AA) women with breast cancer (BC) are diagnosed with more aggressive disease, have higher risk of recurrence and poorer prognosis as compared to Caucasian American (CA) women. Therefore, it is imperative to define the factors associated with such disparities to reduce the unequal burden of cancer. Emerging data suggest that inherent(More)
N-Myc Interactor is an inducible protein whose expression is compromised in advanced stage breast cancer. Downregulation of NMI, a gatekeeper of epithelial phenotype, in breast tumors promotes mesenchymal, invasive and metastatic phenotype of the cancer cells. Thus the mechanisms that regulate expression of NMI are of potential interest for understanding(More)
Methods for evaluating intestinal ischemia include standard clinical criteria, Doppler ultrasonography, and intravenous fluorescein injection. Each has disadvantages, and a combination of methods is often used. The purpose of this study was to determine whether surface oximetry could be used to assess perfusion in an animal whose intestinal diameter(More)
Non-steroidal anti-inflammatory drugs (NSAIDs) have been widely reported to display strong efficacy for cancer chemoprevention, although their mechanism of action is poorly understood. The most well-documented effects of NSAIDs include inhibition of tumor cell proliferation and induction of apoptosis, but their effect on tumor cell invasion has not been(More)
