| 2 | 柑桔黄龙病的鉴定和柯赫氏定理(英文)显示文摘黄龙(梢)病被认为是世界柑橘生产上的毁灭性病害已超过一个世纪,但该病害的病原学至今还没有清晰地建立起来。根据16S rRNA基因序列分析,一组被称为'Candidatus Liberibacter species'的难培养细菌被认为与黄龙病相关。然而,要确定'Ca.Liberibacter spp.'是黄龙病病原的柯赫氏定理并没有真正完成。令我们担忧的是,近年来有些文献频频指出'Ca.Liberibacter spp.'是黄龙病的病原,其实该细菌与柑橘寄主的直接病理反应还没有完全确定。我们建议,在黄龙病病原学清楚之前,文献报道在这方面需要有准确的阐述。 | Chen J Deng X Civerolo E L Lee R F Jones J B Zhou C Hartung J S Manjunath K L Brlansky R H | 2011 | 植物病理学报2011,41,2: | 10 |
| 3 | 开关电容PWM DC-DC电压调节模块显示文摘介绍了一种开关电容PWM DC-DC电压调节模块,该变换器是开关电容变换器和PWM变换器的结合,具有如下优点:①开关管的零电压开关(Zero-Voltage-Switching,ZVS);②运用自耦变压器实现同步整流管(Synchronous Rectifier,SR)的自驱动,减小了驱动损耗和体二极管导通损耗;③变压器漏感对效率的影响小,可以使用常规的分立式变压器,从而降低成本;④变换器是单相的,结构简单,应用灵活。在理论分析的基础上,搭建了一台四相700kHz 1.2V/130AVRM原理样机验证了理论分析的正确性。 | 曹文静 金科 Ming Xu F C Lee | 2012 | 电工技术学报2012,27,10: | 8 |

| 6 | Increased catabolism and decreased unsaturation of ganglioside in patients with inflammatory bowel disease显示文摘AIM: To investigate whether accelerated catabolism of ganglioside and decreased ganglioside content contribute to the etiology of pro-inflammatory intestinal disease. METHODS: Intestinal mucosa from terminal ileum or colon was obtained from patients with ulcerative colitis or inflammatory Crohn's disease(n = 11) undergoing bowel resection and compared to control samples of normal intestine from patients with benign colon polyps(n = 6) and colorectal cancer(n = 12) in this observational case-control study. Gangliosides and phospholipids of intestinal mucosa were characterized by class and ceramide or fatty acid composition using liquid chromatography triple-quad mass spectrometry. Content and composition of ganglioside classes GM1, GM3, GD3, GD1 a, GT1 and GT3 were compared among subject groups. Content and composition of phospholipid classes phosphatidylcholine(PC) and phosphatidylethanolamine were compared among subject groups. Unsaturation index of individual ganglioside and phospholipid classes was computed and compared among subject groups. Ganglioside catabolism enzymes beta-hexosaminidase A(HEXA) and sialidase-3(NEU3) were measured in intestinal mucosa using western blot and compared among subject groups. RESULTS: Relative GM3 ganglioside content was 2-fold higher(P < 0.05) in intestine from patients with inflammatory bowel disease(IBD) compared to control intestine. The quantity of GM3 and ratio of GM3/GD3 was also higher in IBD intestine than control tissue(P < 0.05). Control intestine exhibited 3-fold higher(P < 0.01) relative GD1 a ganglioside content than IBD intestine. GD3 and GD1 a species of ganglioside containing three unsaturated bonds were present in control intestine, but were not detected in IBD intestine. The relative content of PC containing more than two unsaturated bonds was 30% lower in IBD intestine than control intestine(P < 0.05). The relative content of HEXA in IBD intestine was increased 1.7-fold(P < 0.05) and NEU3 was increased 8.3-fold(P < 0.01) compared to normal intestine. Intestinal mucosa in IBD is characterized by increased GM3 content, decreased GD1 a, and a reduction in polyunsaturated fatty acid constituents in GD3, GD1 a and PC.CONCLUSION: This study suggests a new paradigm by proposing that IBD occurs as a consequence of increased metabolism of specific gangliosides. | John J Miklavcic Glen K Shoemaker Vera C Mazurak M Tom Clandinin Tasha DL Hart Kareena L Schnabl Gordon M Lees Bodil MK Larsen Oliver F Bathe Alan BR Thomson M Tom Clandinin | 2015 | World Journal of Gastroenterology2015,21,35: | 3 |
