| 1 | Characterisation of human non-proliferative diabetic retinopathy using the fractal analysis显示文摘· AIM: To investigate and quantify changes in the branching patterns of the retina vascular network in diabetes using the fractal analysis method.·METHODS: This was a clinic-based prospective study of 172 participants managed at the Ophthalmological Clinic of Cluj-Napoca, Romania, between January 2012 and December 2013. A set of 172 segmented and skeletonized human retinal images, corresponding to both normal(24 images) and pathological(148 images)states of the retina were examined. An automatic unsupervised method for retinal vessel segmentation was applied before fractal analysis. The fractal analyses of the retinal digital images were performed using the fractal analysis software Image J. Statistical analyses were performed for these groups using Microsoft Office Excel2003 and Graph Pad In Stat software.·RESULTS: It was found that subtle changes in the vascular network geometry of the human retina are influenced by diabetic retinopathy(DR) and can be estimated using the fractal geometry. The average of fractal dimensions D for the normal images(segmented and skeletonized versions) is slightly lower than the corresponding values of mild non-proliferative DR(NPDR) images(segmented and skeletonized versions).The average of fractal dimensions D for the normal images(segmented and skeletonized versions) is higher than the corresponding values of moderate NPDR images(segmented and skeletonized versions). The lowestvalues were found for the corresponding values of severe NPDR images(segmented and skeletonized versions).· CONCLUSION: The fractal analysis of fundus photographs may be used for a more complete understanding of the early and basic pathophysiological mechanisms of diabetes. The architecture of the retinal microvasculature in diabetes can be quantitative quantified by means of the fractal dimension.Microvascular abnormalities on retinal imaging may elucidate early mechanistic pathways for microvascular complications and distinguish patients with DR from healthy individuals. | Stefan Tǎlu Dan Mihai Cǎlugǎru Carmen Alina Lupascu | 2015 | International Journal of Ophthalmology(English edition)2015,8,4: | 4 |
| 2 | Effect of a bacterial inoculum and additive on dry matter in situ degradability of sugarcane silage显示文摘The objective of this study was to evaluate the effect of adding a bacterial inoculum and a handmade additive to sugarcane silage(SCS) on the in situ digestibility of dry matter(DM). The treatments were: T1) sugarcane silage(SCS) and T2) sugarcane silage with 1% inoculum and 1% additive(SCS+). The bacterial inoculum consisted of 10.0% molasses, 1.0% yogurt, 5.0% chicken manure, 0.5% urea, and 83.0% water, and the additive was formulated with 1.0% urea, 0.1% ammonium sulfate, and 0.25% phosphorus. In situ dry matter digestibility(DMD) was determined using the nylon bag technique with four cows equipped with ruminal fistulas. Cows were fed with ensiled sugarcane supplemented with 1 kg of commercial concentrate. 5 g of ground sample for each sugarcane treatment were weighted in nylon bags and incubated for 4, 8, 12, 24, 48, and 72 h in a completely randomized design with six replicates. The DMD(%) was higher(P<0.05) for SCS+ for all incubation times when compared with SCS. There were no differences in ruminal p H between the treatments for all the incubation times. The data suggested that the sugarcane silage with bacterial inoculum and additive could be an alternative for providing forage for ruminants during the season of low growth and quality grass. | José A Reyes-Gutiérrez Oziel D Montaez-Valdez Ramón Rodríguez-Macias Mario Ruíz-López Eduardo Salcedo-Pérez Cándido E Guerra-Medina | 2015 | Journal of Integrative Agriculture2015,14,3: | 3 |
