1Role of live microbial feed supplements with reference to anaerobic fungi in ruminant productivity: A review显示文摘To keep the concept of a safe food supply to the consumers, animal feed industries world over are showing an increasing interest in the direct-fed microbials(DFM) for improved animal performance in terms of growth or productivity. This becomes all the more essential in a situation, where a number of the residues of antibiotics and/or other growth stimulants reach in milk and meat with a number of associated potential risks for the consumers. Hence, in the absence of growth stimulants, a positive manipulation of the rumen microbial ecosystem to enhance the feedstuff utilization for improved production efficiency by ruminants has become of much interest to the researchers and entrepreneurs. A few genera of live microbes(i.e., bacteria, fungi and yeasts in different types of formulations from paste to powder) are infrequently used as DFM for the domestic ruminants. These DFM products are live microbial feed supplements containing naturally occurring microbes in the rumen. Among different DFM possibilities, anaerobic rumen fungi(ARF) based additives have been found to improve ruminant productivity consistently during feeding trials. Administration of ARF during the few trials conducted, led to the increased weight gain, milk production, and total tract digestibility of feed components in ruminants. Anaerobic fungi in the rumen display very strong cell-wall degrading cellulolytic and xylanolytic activities through rhizoid development, resulting in the physical disruption of feed structure paving the way for bacterial action. Significant improvements in the fiber digestibility were found to coincide with increases in ARF in the rumen indicating their role. Most of the researches based on DFM have indicated a positive response in nutrient digestion and methane reducing potential during in vivo and/or in vitro supplementation of ARF as DFM. Therefore, DFM especially ARF will gain popularity but it is necessary that all the strains are thoroughly studied for their beneficial properties to have a confirmed ‘generally regarded as safe' status for ruminants.Anil K Puniya Abdelfattah Z M Salem Sanjay Kumar Sumit S Dagar Gareth W Griffith Monica Puniya Sreenivas R Ravella Nikhil Kumar Tejpal Dhewa Ravinder Kumar 2015Journal of Integrative Agriculture2015,14,3:17
2红外光谱法和主成分分析法用于胃组织癌变的检测(英文)显示文摘研究了 2 1例胃组织光谱 ,根据病理检测结果 ,其中 11例为癌变组织 ,10例为正常组织。根据已有的红外光谱判别方法得到的结果和病理分析结果基本一致 ,只有 1例 (第 10号样品 )为过渡态 ,非典型癌症。同时对 2 1条被测光谱进行了主成分分析 (PCA)。主成分分析结果表明第一主成分可以用来区别胃正常组织和癌变组织光谱。图 4明确地显示了第 10号样品处于过渡态 ,PCA方法的判别结果与红外光谱解析结果基本一致。研究结果表明傅里叶变换红外光谱法与主成分分析方法都可以对良性和恶性胃组织进行鉴别诊断 ,如果两种方法相结合可以提高检测准确率 。Peter R Griffiths 杨虎生 李庆波 凌晓锋 王健生 杨丽敏 徐怡庄 翁诗甫 吴瑾光 2004光谱学与光谱分析2004,24,9:11
