The application of organic soil amendments is a common practice for increasing soil fertility and soil organic carbon (SOC) content. In recent years, a new product from biogas production, biogas slurry is increasingly applied to agricultural soils, although little is known about its effects on soil properties. In this study, the influence of this new product in comparison with liquid manure and sewage sludge on the organic carbon dynamics and enzyme activities were investigated in two different agricultural soils in short-term incubation studies. As a control, biologically inert sand was also amended with these organic wastes. In sand, biogas slurry degraded to 10.4% within 14 days, while no differences were found between the degradability of liquid manure and sewage sludge with 6.6% and 5.4%, respectively. However, although the degradability of biogas slurry was highest among the organic amendments, liquid manure application resulted in the highest respiration rates in the soil samples. This was likely due to the organic waste borne easily decomposable substrates which were most dominant in liquid manure. Organic waste applications were found to generally increase the activity of numerous enzymes but did not change the soil enzyme patterns. Thus, in general it was shown that the microbial population of the organic wastes will not become prominent when introduced with the manures to soils. Thus, an inoculation with organic waste borne microorganisms could likely be neglected when discussing the extent of organic carbon dynamics after organic waste application to agricultural soils.

Background: In this study, we describe our clinical experience with the fifth-generation of a breast implant with a smooth, fine surface from a Korean manufacturer (BellaGel® SmoothFine;HansBiomed Co. Ltd., Seoul, Korea) in Asian women. Methods: We analyzed 223 women (mean age = 35.28 ± 9.45 years and mean follow-up period = 12.03 ± 2.48 months), comprising 118 bilateral cases and 109 unilateral ones, who received breast augmentation using the BellaGel® SmoothFine at our hospital between June 4, 2018 and February 28, 2019. For safety assessment, we analyzed frequencies of postoperative complications and overall survival of the BellaGel® SmoothFine. Results: Postoperatively, complications (12 cases, 5.38%) include asymmetry (3 cases, 1.35%), hematoma (2 cases, 0.90%), hypertrophic scars (2 cases, 0.90%), wound disruption (2 cases, 0.90%), rippling (1 case, 0.45%), capsular contracture (1 case, 0.45%), stretch deformities with skin excess (1 case, 0.45%). In addition, time-to-events were calculated as 10.94 ± 0.64 months (95% CI 9.69 - 12.19) and the survival rate reached 0.290 ± 0.168 (95% CI 0.094 - 0.901) at 12 months postoperatively. Conclusions: Here, we describe our clinical experience with the BellaGel® SmoothFine. Our results are of significance in that this is the first report about the fifth-generation of a breast implant with a smooth, fine surface from a Korean manufacturer for Asian women.

作者： Sarah E.Walker Gaynor E.Spencer robert L.Carlone Department of Biological Sciences Brock University

In the development and regeneration of the nervous system, neurons face the complex task of establishing and/or repairing neuronal connections and contacts. The formation of these neuronal circuits is largely coordinated by tightly regulated temporal and spatial changes in mRNA translation, which enables incredibly precise control over protein expression and localization (jung and Holt, 2011). Local mRNA translation in specific cellular compartments appears to play a role in many processes that are important to nervous system development and regeneration, including: cell survival, migration, growth cone guidance, and synaptogenesis (jung and Holt, 2011).
