More high-quality studies are necessary for drawing more reliable and convincing conclusions.”
“The aims of this study were to establish a rat model of carotid artery injury and to evaluate its suitability for evaluating therapeutic agents active against endothelial proliferation. Wistar-Kyoto rats were injected intravenously with the photochemically reactive dyes rose bengal or Evans blue, and the carotid artery was then focally irradiated with laser light of the appropriate
wavelength. Histological sections of the carotid artery were analyzed OSI-906 mouse to determine the appropriate parameters for this model. Ferulic acid was used to assess the suitability of this model for drug screening. No animal died as a result of the photochemical treatment. Endothelial proliferation in the carotid artery was observed in rats injected with rose Bengal and exposed to green laser light. Ferulic acid (400 mg/kg per day) significantly (p < 0.05) reduced endothelial proliferation in the carotid artery 28 days after injury in dye-treated animals compared with vehicle-treated animals. This simple experimental rat model is suitable for studying factors inhibiting endothelial thickening after vessel damage and for developing therapeutic strategies active against endothelial proliferation.”
“The performance of sodium carbonate-sodium sulfite (Na2CO3-Na2SO3) pretreatment
on improving the enzymatic hydrolysis of rice straw was investigated. The results indicated that both Na2CO3 and Na2SO3 pretreatments are effective in improving the enzymatic digestibility of
rice this website straw. A higher ratio of Na2SO3 in pretreatment liquor performed better at softening the rice straw through degradation of hemicellulose, delignification, and lignin sulfonation, while it was conserving more polysaccharides during the pretreatment than Na2CO3. The highest sugar recovery of pretreated rice straw, 74.5%, 82.7%, and 59.5% for total sugar, glucan, and xylan, respectively, was obtained at cellulase loading of 20 FPU/g-cellulose after the pretreatment at 140 degrees C, chemical charge of 12%, Na2CO3-Na2SO3 ratio of 0:1 (i.e., only Na2SO3 Nocodazole price pretreatment). The corresponding delignification ratio of pretreated solid was 53.4%, and 91.4% of the polysaccharides were conserved. The sugar recovery of only Na2CO3 pretreatment at the ratio of 1:0 was 67.1%. 74.4%, and 53.7% for total sugar, glucan, and xylan, respectively, at 140 degrees C, chemical charge of 12%, and enzyme loading of 20 FPU/g-cellulose. Its corresponding delignification ratio was 40.3%, and polysaccharides conservation ratio was 88.9%. (c) 2012 Elsevier B.V. All rights reserved.”
