The family of vascular endothelial growth factor (VEGF) proteins include potent and specific mitogens for vascular endothelial cells that function in the lation of angiogenesis Inhibition of VEGF-induced angiogenesis either by neutralizing antibodies or dominant-negative soluble receptor, blocks the growth of primary and metastatic experimental tumors Here(More)
BACKGROUND The impact of intraoperative erythrocyte transfusion on outcomes of anemic patients undergoing noncardiac surgery has not been well characterized. The objective of this study was to examine the association between blood transfusion and mortality and morbidity in patients with severe anemia (hematocrit less than 30%) who are exposed to one or two(More)
Angiostatin, a proteolytic fragment of plasminogen, inhibits the growth of primary and metastatic tumors by suppressing angiogenesis. When used in combination with ionizing radiation (IR), angiostatin demonstrates potent antitumor synergism, largely caused by inhibition of the tumor microvasculature. We report here the temporal interaction of angiostatin(More)
Toll-like receptor-9 (TLR-9) agonists have pleotropic effects on both the innate and adaptive immune systems, including increased antigen expression, enhanced antibody-dependent cell-mediated cytotoxicity (ADCC) and T helper cell type 1 shift in the immune response. We combined a TLR-9 agonist (1018 ISS, 0.2 mg/kg sc weekly x 4 beginning day 8) with(More)
In the critically ill surgical patient a variety of therapeutic maneuvers is required to maintain a "healthy gut." Provision of adequate amounts of glutamine to the gastrointestinal mucosa appears to be just one of these maneuvers. Other methods utilized to protect the gut from becoming a wound include: (a) minimizing additional systemic insults (such as(More)
Glutamine may be an essential dietary component, especially for the support of intestinal mucosal growth and function. This study evaluated the effects of a glutamine-enriched elemental diet, administered before whole-abdominal radiation on gut glutamine metabolism, mucosal morphometrics, and bacterial translocation. Rats were randomized to receive a(More)
OBJECTIVE To establish the relationship between operative approach (laparoscopic or open) and subsequent surgical infection (both incisional and organ space infection) postappendectomy, independent of potential confounding factors. BACKGROUND Although laparoscopic appendectomy has been associated with lower rates of incisional infections than an open(More)
PURPOSE Although morbidity and mortality (M & M) conferences are cornerstones of surgical teaching, they are not consistent in their educational quality. The current study examines the content and process of M & M presentations by surgical residents and hypothesizes that a structured format for these presentations can improve teaching and learning.

BACKGROUND We performed a cost-benefit analysis of minimally invasive colectomy (MIC) with the appreciation that this approach extends the duration of the operation and requires additional instruments and equipment when compared with the open procedure. These negatives may be offset by decreased pain, earlier initiation of oral feeding, and a shorter(More)
The healing effects of glutamine given orally for 8 days as a single amino acid nutrient after treatment with whole abdominal radiation (10 Gy) were studied. Rats received isonitrogenous and isovolumic diets containing 3% glutamine or 3% glycine. Control rats were not irradiated but were given identical diets. In irradiated animals, survival was 100% in(More)
