We present an Euler-Lagrange method for the simulation of wood gasification in a bubbling fluidized bed. The gas phase is modeled as a continuum using the 2D Navier-Stokes equations and the solid phase is modeled by a Discrete Element Method （DEM） using a soft-sphere approach for the particle collision dynamic. Turbulence is included via a Large-Eddy approach using the Smagorinsky sub-grid model. The model takes into account detailed gas phase chemistry, zero-dimensional modeling of the pyrolysis and gasification of each individual particle, particle shrinkage, and heat and mass transfer between the gas phase and the particulate phase. We investigate the influence of wood feeding rate and compare exhaust gas compositions and temperature results obtained with the model against experimental data of a laboratory scale bubbling fiuidized bed reactor.

The detoxification of iron cyanide in a soil–plant system was investigated to assess the total cyanide extracted from contaminated soil and allocated in the leaf tissue of willow trees(Salix caprea). They were grown in soil containing up to 1000 mg/kg dry weight(dw) of cyanide(CN),added as ^(15)N-labeled potassium ferrocyanide and prepared with a new method for synthesis of labeled iron cyanides. CN content and ^(15)N enrichment were monitored weekly over the exposure in leaf tissue of different age. The ^(15)N enrichment in the young and old leaf tissue reached up to 15.197‰ and 9063‰, respectively; it increased significantly over the exposure and with increasing exposure concentrations(p < 0.05). Although the CN accumulation in the old leaf tissue was higher, compared to the young leaf tissue(p < 0.05), the ^(15)N enrichment in the two tissue types did not differ statistically. This indicates a non-uniform CN accumulation but a uniform ^(15)N allocation throughout the leaf mass. Significant differences were detected between the measured CN content and the C^(15)N content, calculated from the ^(15)N enrichment(p < 0.05), revealing a significant CN fraction within the leaf tissue, which could not be detected as ionic CN. The application of labeled iron CN clearly shows that CN is detoxified during uptake by the willows. However, these results do not exclude other detoxification pathways, not related to the trees. Still, they are strongly indicative of the central role the trees played in CN removal and detoxification under the experimental conditions.

AIM: To investigate whether the routine use of fibrin glue applied onto the hepatic resection area can diminish postoperative volume of bloody or biliary fluids drained via intraoperatively placed perihepatic tubes and can thus lower the complication ***: Two groups of consecutive patients with a comparable spectrum of recent hepatic resections were compared: (1) 13 patients who underwent application of fibrin glue immediately after resection of liver parenchyma;(2) 12 patients who did not. Volumes of postoperative drainage fluid were determined in 4-h intervals through 24 h indicating the intervention caused bloody and biliary ***: Through the first 8 h postoperatively, there was a tendency of higher amounts of fluids in patients with no additional application of fibrin glue while through the following intervals, a significant increase of drainage volumes was documented in comparison with the first two 4-h intervals, e.g., after 12 h, 149.6 mL +/-110 mL vs 63.2 mL +/-78 mL. Using fibrin glue, postoperative fluid amounts were significantly lower through the postoperative observation period of 24 h (851 mL +/-715 mL vs 315 mL +/-305 mL).CONCLUSION: For hepatic resections, the use of fibrin glue appears to be advantageous in terms of a significant decrease of surgically associated segregation of blood or bile out of the resection area. This might result in a better outcome.

Interleukin-33 （IL-33）, a cytokine of the IL-1 family, has been implicated inthe pathogenesis of liver fibrosis for quite some time. Indeed, IL-33 expression is upregulated in both human and murine hepatic fibrosis.1,2 To date, it is believed that IL-33 serves as an ‘alarmi’ released by stressed hepatocytes. IL-33 then attracts type 2 innate lymphoid cells （ILC）, which trigger the profibrogenic activation of hepatic stellate cells via mediators such as IL-13.

With the rising interest in the regulatory functions of long non-coding RNAs （IncRNAs） in complex human diseases such as cardiovascular diseases, there is an increasing need in public databases offering comprehensive and integrative data for all aspects of these versatile molecules. Recently, a variety of public data repositories that specialized in lncRNAs have been developed, which make use of huge high-throughput data particularly from next-generation sequencing （NGS） approaches. Here, we provide an overview of current IncRNA databases covering basic and functional annotation, IncRNA expression and regulation, interactions with other biomolecules, and genomic variants influencing the structure and function of lncRNAs. The prominent IncRNA antisense noncoding RNA in the INK4 locus （ANRIL）, which has been unequivocally associated with coronary artery disease through genome-wide association studies （GWAS）, serves as an example to demonstrate the features of each individual database.

Heavy metal extraction and processing from ores releases elements into the environment. Soil, being an "unfortunate" sink, has its bionomics impaired and affected by metal pollution. Metals sneak into the food chain and pose risk to humans and other edaphicdependent organisms. For decontamination, the use of an ecosystem-friendly approach involving plants is known as *** this study, different lead(Pb) concentrations(80, 40, 20, and 10 mg kg^(-1)) were used to contaminate a well-characterized soil,(un)supplemented with organic waste empty fruit bunch(EFB) or spent mushroom compost(SMC), with non-edible plant—Lantana camara. Lead removal by L. camara ranged from 45.51% to 88.03% for supplemented soil, and from 23.7% to 57.8% for unsupplemented soil(P < 0.05). The EFB-supplemented and L. camara-remediated soil showed the highest counts of heavy metal-resistant bacteria(HMRB)(79.67 × 10~6–56.0 × 10~6 colony forming units(CFU) g^(-1) soil), followed by SMC-supplemented and L. camara-remediated soil(63.33 × 10~6–39.0 × 10~6 CFU g^(-1) soil). Aerial metal uptake ranged from 32.08 ± 0.8 to 5.03 ± 0.08 mg kg^(-1) dry weight, and the bioaccumulation factor ranged from 0.401 to 0.643(P < 0.05). Half-lives(t_(1/2)) of Pb were 7.24–2.26 d in supplemented soil,18.39–11.83 d in unsupplemented soil, and 123.75–38.72 d in the soil without plants and organic waste. Freundlich isotherms showed that the intensity of metal absorption(n) ranged from 2.44 to 2.51 for supplemented soil, with regression coefficients of determination(R^2) between 0.901 2 and 0.984 0. The computed free-energy change(?G) for Pb absorption ranged from -5.01 to 0.49 kJ mol^(-1) K^(-1) for EFB-supplemented soil and -3.93 to 0.49 k J mol^(-1) K^(-1) for SMC-supplemented soil.
