Given that a by-product (pyrolytic lignin) is obtained with similar properties to the lignin from wood pulping manufacturing, the perspectives for the viability of lignocellulosic biomass valorization are promising, which is essential for furthering its implementation in biorefinery processes.

“Objective: To identify anatomical factors associated with major adverse limb events (MALE) after angioplasty as the basis for a novel morphology-driven classification of infrapopliteal lesions.
Design: Retrospective-multicenter study.
Materials and methods: Between March 2004 and October 2010, 1057 limbs from 884 patients with CLI due to isolated infrapopliteal lesions were studied. Freedom-from MALE, defined as major amputation or any reintervention, was assessed out to 2 years by the Kaplan-Meier methods. Anatomical predictors and risk stratification for MALE were analyzed by multivariate analysis.
Results: C188-9 Freedom-from MALE was 47 +/- 1% at 2 years. Lesion calcification, target vessel diameter<3.0 mm, lesion length>300 mm and no below-the-ankle (BA) run-off were positively associated with MALE by multivariate-analysis. The total number of risk factors was used to calculate the risk score for each limbs for subsequent categorization into 3 groups with 0 or 1 (low-risk), 2 (moderate-risk) and 3 or 4
(high-risk) factors. Freedom-from MALE at 2 year-rates was 59% in low-risk, 46% in moderate-risk, and 29% in high-risk, respectively.
Conclusion: GSK1210151A supplier Target vessel diameter <3.0 mm, lesion calcification, lesion length > 300 mm Small molecule library and no-BA runoff were associated with MALE after
infrapopliteal angioplasty. Risk stratification based on these predictors allows estimation of future incidence of MALE in CLI with isolated infrapopliteal lesions. (C) 2012 European Society for Vascular Surgery. Published by Elsevier Ltd. All rights reserved.”
“BACKGROUND: Disintegration was developed as a pretreatment process for sludge to accelerate the digestion processes. Ultrasonic treatment may be a good alternative for sludge disintegration. In this study, different specific energy inputs ranged between 0 and 15 880 kJ kg(-1) and very low ultrasonic densities ranged between 0.04 and 0.1 W mL(-1) were applied to biological sludge for disintegration purposes. The potential for improving anaerobic digestion through ultrasonic pre-treatment and the effect of ultrasonic pre-treatment on the filterability characteristics of sludge were also investigated.
RESULTS: 9690 W kg(-1) TS of supplied energy and very low power density of 0.09 Wm L-1 are efficient for floc disintegration. For 9690 kJ kg(-1) TS, 44% higher methane production was achieved than with raw sludge as a result of biochemical methane potential assay. The supernatant characteristics of the sludge were also affected by the ultrasonic pre-treatment.
