Objective: To determine the association between the acute inflammatory markers and Diabetic Renal-Retinal Syndrome in our patients. Methods: A total of 44 patients were included in this transverse (cross sectional), observational, analytical, and comparative study. Two groups of patients were created. Results: In patients with chronic renal failure, stages 3, 4, or 5 (scale 1 to 5) were identified and divided into two groups: Group I (Patients with concomitant diabetic retinopathy stabilized with photocoagulation) 22 patients. Group II (Patients with progression of retinopathy, after photocoagulation, in the form of intraocular bleeding) 22 patients. The number of patients with chronic renal failure in stage 3 was: Group I;16. In Group II;12 patients (OR: 1.0). Stage 4: Group I;4 patients. Group II: 3 patients (OR: 1.0, CI 95%;0.3843 - 2.021). Stage 5: Group I;2 patients. Group II;7 patients (OR: 1.8148, CI 95%;1.0448 - 3.1523;Chi-squared (x2) 2.7450, p = 0.097). t-Test found statistical significance in Erythrocyte Sedimentation Rate (ESR): p < 0.0001 (CI 95%;7.8959 - 23.2515);R = 0.56 p = 0.001;and OR = 1.959 (CI 95%;1.193 - 3.217). By non-parametric tests, C-reactive protein with binomial test showed p < 0.001. ESR showed p < 0.001 with U of Mann Whitney. Conclusions: With this study revealed a possible association of inflammatory markers with Diabetic Renal-Retinal Syndrome.

Polyurethane as substrate for fungal strains

引用

Advances in Bioscience and Biotechnology 2011年第2期2卷 52-58页

Polyurethane is a versatile plastic with several industrial applications in the modern life, but it is considered as a very recalcitrant material. Biodegradation of this plastic has been poorly explored, and most of the studies that have been published focus on bacterial enzymes. In this work, some fungi with the capacity of growing with polyurethane foam as nutrient source were isolated from sands contaminated with this plastic and from DIA/UAdeC collection, testing their ability to grow on polyurethane as sole carbon and nitrogen sources and their enzymatic activities were determined in specific media as well as their invasion capacity on polyurethane agar plates. 22 fungal strains demonstrated their capacity of growing on polyurethane. Among the enzymatic activities evaluate, the most common was the urease activity (95% of the strains).Protease, esterase and laccase activities were present in 86%, 50% and 36% respectively. The great ability of the isolated fungal strains to use polyurethane foam as nutrient opens an important opportunity to study at detail the biodegradation of this plastic, with clear implications in cell biology and environmental technology.
