BACKGROUND:Upper gastrointestinal(GI)bleeding is a common complication of portal hypertension in cirrhotic patients,and hepatocellular carcinoma(HCC)is the most common tumor in cirrhotic *** from tumor erosion into the GI tract is very rare.A patient with HCC and gastric tumor invasion was described and the previously reported cases were reviewed. METHOD:A patient with upper GI bleeding was treated in a tertiary hospital. RESULTS:A cirrhotic patient with a HCC invading the stomach leading to upper GI bleeding was treated by left lateral segmentectomy and sub-total *** bleeding was controlled and a good surgical outcome was achieved. CONCLUSIONS:HCC with gastric invasion should be differentially diagnosed from upper GI bleeding in cirrhotic *** can be controlled and symptomatic relief marked in selected cases.

Calculation of Percentage of Coarse Aggregate Present in Concrete Using Processing of Digital Images Obtained with a Commercial Scanner

引用

Journal of Chemistry and Chemical Engineering 2015年第2期9卷 136-139页

This paper presents a method for determining the percentage of coarse aggregate in concrete specimens by image processing. The test pieces were produced with the aim of obtaining images of their cross sections through a scanner table. In order to increase the contrast between mortar and coarse aggregate the sliced surfaces were treated with the phenolphthale in solution. The images obtained in the scanner were processed in a program developed with MATLAB （matrix laboratory）. The average coarse aggregate in each section and the mean of coarse aggregate per test body were calculated. With the results, it was revealed that the method returned satisfying results when compared to the original trace of the concrete.

Grape processing generates residues rich in bioactive compounds with potential application in the meat ***,these substances are unstable and needs to be treated to allow their action during the processing and storage of meat *** this sense,a phenolic-rich extract from grape pomace was microencapsulated and evaluated for its potential to inhibit the oxidative process in raw and precooked beef burgers during cold *** hamburger formulations containing lyophilized extract(LEB),microencapsulated extract(MEB)and synthetic antioxidant sodium erythorbate(SEB)were prepared,pre-cooked,and evaluated for lipid and protein *** microencapsulation,with 95.0%efficiency,provided a material with a crystalline structure,rich in phenolics and with high antioxidant potential,showing 377.4±0.01,1768.1±0.07 and 1185.0±0.20μmol TEAC.100 g−1 for DPPH,ABTS and FRAP,*** values of malonaldehyde were found in LEB and MEB(2.9±0.3 and 1.4±0.5 mg ***−1,respectively)at the end of storage,with emphasis on for the hamburgers that received the microencapsulated *** behavior was observed for the analysis of carbonyl compounds,with values of 11.1±1.1,8.7±1.4 and 6.8±1.0 nM ***−1 in SEB,LEB and MEB,***,the freeze-dried and microencapsulated grape extracts showed superior results when compared to the synthetic antioxidant,increasing the oxidative stability of hamburgers,and avoiding significant color changes during the cold *** results indicate the high potential of the microencapsulated material to be used as a natural antioxidant in the meat industry.
