[EX Q]: Severity of pancreatitis seems to be aggravated by impairment of vascular perfusion of the gland. Early mortality occurs within the first few days from the acute consequences of pancreatic injury with subsequent inflammatory response. Because vasoactive substances, including endothelin, seem to contribute to early mortality in acute pancreatitis, we tested the hypothesis that the inhibition of endothelin action could alter the outcome after severe experimental pancreatitis.', 'In two groups of rats, pancreatitis was induced by intraductal infusion into the pancreatic duct of 1 microL/g body weight (b.w.) of either a 4% or a 5% sodium taurocholate solution. The mixed endothelin A and endothelin B receptor antagonist bosentan (20 mg/kg b.w.) or vehicle was injected intravenously in 12-h intervals for 3 d starting 1 h after induction of bile acid pancreatitis. This dose of bosentan is known to completely inhibit the effect of exogenous endothelin. The survival rate was monitored for 7 d. Thereafter, the surviving rats were sacrificed and the pancreas was prepared for histological and biochemical evaluation.', 'Irrespective of the treatment protocol (bosentan versus saline), survival was not different in animals challenged with either 4% or 5% sodium taurocholate. The corresponding survival rates were 62% with bosentan and 77% without bosentan in the 4% sodium taurocholate group. In the 5% sodium taurocholate group, the survival rates were 20% with and 27% without bosentan. Morphological and biochemical alterations were identical in control as well as in endothelin-antagonist-treated rats.

[EX Q]: Environmental ozone can rapidly degrade cyanine 5 (Cy5), a fluorescent dye commonly used in microarray gene expression studies. Cyanine 3 (Cy3) is much less affected by atmospheric ozone. Degradation of the Cy5 signal relative to the Cy3 signal in 2-color microarrays will adversely reduce the Cy5/Cy3 ratio resulting in unreliable microarray data.', 'Ozone in central Arkansas typically ranges between approximately 22 ppb to approximately 46 ppb and can be as high as 60-100 ppb depending upon season, meteorological conditions, and time of day. These levels of ozone are common in many areas of the country during the summer. A carbon filter was installed in the laboratory air handling system to reduce ozone levels in the microarray laboratory. In addition, the airflow was balanced to prevent non-filtered air from entering the laboratory. These modifications reduced the ozone within the microarray laboratory to approximately 2-4 ppb. Data presented here document reductions in Cy5 signal on both in-house produced microarrays and commercial microarrays as a result of exposure to unfiltered air. Comparisons of identically hybridized microarrays exposed to either carbon-filtered or unfiltered air demonstrated the protective effect of carbon-filtration on microarray data as indicated by Cy5 and Cy3 intensities. LOWESS normalization of the data was not able to completely overcome the effect of ozone-induced reduction of Cy5 signal. Experiments were also conducted to examine the effects of high humidity on microarray quality. Modest, but significant, increases in Cy5 and Cy3 signal intensities were observed after 2 or 4 hours at 98-99% humidity compared to 42% humidity.

[EX Q]: Decreased plasma levels of omentin, a relatively novel adipokine, are shown to be associated with metabolic abnormalities and proinflammatory states. Although other adipokines such as leptin and adiponectin have been extensively investigated in patients with major depressive disorder (MDD), no studies have evaluated omentin levels in major depression. Therefore, this study sought to test the hypothesis that drug-naive patients with MDD would have lower serum omentin levels than a healthy control group similar in age, sex, and body mass index.', 'Thirty patients with MDD (10 men) and 30 healthy control subjects (10 men) were studied. Plasma concentration of omentin, along with other biochemical parameters, was measured after a period of fasting. The severity of depression was determined by the Beck Depression Inventory.', 'No significant difference was found between patients with MDD (723.3233.8 ng/ml) and healthy comparison subjects (670.7351.8 ng/ml) in mean plasma concentrations of omentin (p>0.05). There was no significant correlation between plasma omentin levels and depression severity (r=-0.147; p>0.05).
