This study investigated the changes of nutrient compositions of piled laying hen manure, detected the physical and chemical components of laying hen manure fermented by mixed strains, and analysed its application effects on feeding ruminants. The results showed that with increasing of piling time, the contents of crude protein (CP) and ether extract (EE) in laying hen manure were reduced, while the contents of crude ash (CA), calcium (Ca) and phosphorus (P) were increased. Fermentation could effectively decrease pH value, reduce Ca/P ratio, lessen the total bacterial counts, and maintain the organisms contents in laying hen manure...

Transmembrane proteins are sorted from endosomes to avoid lysosomal degradation. A recent study has identified a new multimeric complex called retriever that is essential for recycling numerous cell-surface cargoes from endosomes and is structurally and functionally related to the well-characterised retromer complex.

The lung has a unique relationship to cholesterol that is shaped by its singular physiology. On the one hand, the lungs receive the full cardiac output and have a predominant dependence on plasma lipoprotein uptake for their cholesterol supply. On the other hand, surfactant lipids, including cholesterol, are continually susceptible to oxidation owing to direct environmental exposure and must be cleared or recycled because of the very narrow biophysical mandates placed upon surfactant lipid composition. Interestingly, increased lipid-laden macrophage "foam cells" have been noted in a wide range of human lung pathologies...

REVIEW
Katerina Bakela, Irene Athanassakis
The involvement of Major histocompatibility complex (MHC) antigens in the development and regulation of immune response has been well defined over the years, starting from maturation, antigenic peptide loading, migration to the cell membrane for recognition by the T cell receptor and recycling for immune response cessation. During this intracellular trafficking, MHC antigens find a way to be excreted by the cells, since they can be found as soluble MHC class I (sMHCI) and class II (sMHCII) molecules in all body fluids...

BACKGROUND: A population pharmacokinetic (PK) protein-binding model was developed to (1) predict free mycophenolic acid (fMPA) based on total MPA (tMPA) concentrations in renal transplant patients, to establish the therapeutic range of fMPA through pharmacokinetic-pharmacodynamic studies; and (2) provide a guideline for dosing mycophenolate mofetil (MMF). METHODS: Full PK profiles of 56 patients (from five different occasions) during the first year after transplantation who were treated with oral MMF and cyclosporine, or macrolides (either tacrolimus or sirolimus), were analysed...

Strategies are needed to increase the sustainability of phosphorus (P) fertiliser management in agriculture. This paper reports on the potential of pyrolysis treatment to recycle P from renewable materials previously regarded as wastes. The study used K-edge X-ray absorption near-edge structure (XANES) spectroscopy to examine chemical forms of P in the waste feedstock materials and corresponding biochars (pyrolysis at 480-500 °C) of four ligno-cellulosic, plant-based residues and five relatively P-rich livestock and water-treatment by-products, to acquire information on changes in potential P fertiliser value...

Henson L Lee Yu, Yinghua Zhang, I-Ming Hsing
One of the promising approaches to address the challenge of detecting dilute nucleic acid analytes is exonuclease III-aided target recycling. In this strategy, the target DNA self-assembles with the reactant DNA probes and displays itself as a reactant and product at the same time. This provides an autonomous mechanism to release and reuse the analyte from each round of reactions for repetitive cycles, which amplifies the signal without amplifying the analyte itself. However, for very low amounts of the analyte, it takes a considerably long time before a detectable signal is generated...

Retromer is an endosomal multi-protein complex that organizes the endocytic recycling of a vast range of integral membrane proteins. Here, we establish an additional retromer function in controlling the activity and localization of the late endosomal small GTPase RAB7. Surprisingly, we found that RAB7 not only decorates late endosomes or lysosomes, but is also present on the endoplasmic reticulum, trans-Golgi network, and mitochondrial membranes, a localization that is maintained by retromer and the retromer-associated RAB7-specific GAP TBC1D5...

Synthesis of liquid fuels from waste is a promising pathway for reducing the carbon footprint of transportation industry and optimizing waste management towards zero landfilling. The study of commercial plants that conduct pyrolysis of plastics from post-consumer recycled materials and directly mine from old landfills without any pre-treatment has revealed two cases that show the feasibility of manufacturing transportation fuels via these methods. Pyrolysis oil, consisting of almost 26% hydrocarbons within the gasoline range and almost 70% within the diesel range, is upgraded to transportation fuel in the existing refinery...

This study focused on improving activity and stability of industrial lipases by means of enzymatic immobilization onto spherelike bacterial cellulose (SBC) newly synthesized by a particular bacterial strain (Gluconacetobacter xylinus, JCM 9730). The results revealed that immobilizing lipases onto aldehyde-modified SBC with a size of 6.10±0.50mm could lead to two optimal hydrolytic activities of lipases under both acidic (pH 5) and alkaline conditions (pH 8), which was superior to free lipases that only exhibited an alkaline activity at pH 9...

Agricultural subsurface drainage has been recognized as an important pathway for phosphorus transport from soils to surface waters. Reactive permeable filters are a promising technology to remove phosphate from subsurface drainage. Three natural minerals (limestone, zeolite, and calcite) and five industrial byproducts (steel slag, iron filings, and three recycled steel byproducts) were evaluated for phosphate removal from subsurface drainage using batch adsorption experiments. Phosphate adsorption onto these materials were characterized by Langmuir isotherm and second order kinetic models...

Based on the target-induced catalytic hairpin assembly and bimetallic catalyst, the enzyme-free recycling amplification strategy for sensitive detection of prostate specific antigen (PSA) has been designed. The aptamer and its complementary DNA (C-apt) are modified on the magnetic particles. The aptamer-PSA binding event can release the C-apt that triggers the catalytic assembly between hairpin capture DNA and hairpin help DNA. Then the catalytic hairpin assembly leads to cyclic reuse the C-apt and the generation of many opened hairpin capture DNA, which can associate with the prepared Au/Pt-polymethylene blue (PMB) probes to yield electrochemical signal...

Landfilling of food waste due to its low recycling rate is raising serious concerns because of associated soil and water contamination, and emission of methane and other greenhouse gases during the degradation process. This paper explores feasibility of using biochar derived from mixed food waste (FWBC), rice waste (RWBC) and wood waste (mixed wood saw dust, MWBC) as carbon sequestering additive in mortar. RWBC is prepared from boiled plain rice, while FWBC is prepared from combination of rice, meat, and vegetables in fixed proportion...

Calcium looping (CaL) is a post-combustion CO2 capture technology that is suitable for retrofitting existing power plants. The CaL process uses limestone as a cheap and readily available CO2 sorbent. While the technology has been widely studied, there are a few available options that could be applied to make it more economically viable. One of these is to increase the oxygen concentration in the calciner to reduce or eliminate the amount of recycled gas (CO2, H2O and impurities); therefore, decreasing or removing the energy necessary to heat the recycled gas stream...

Efficient capture and recycling of CO2 enable not only preventing global warming but also to supplying useful low-carbon fuels. The catalytic conversion of CO2 into organic compound is a promising recycling approach which opens new concepts and opportunities for catalytic and industrial development. Here we report about template-assisted wet-combustion synthesis of one-dimensional nickel-based catalyst for carbon dioxide methanation and methane steam reforming. Due to a high temperature achieved in a short time during reaction and a large amount of gases evolved, the wet-combustion synthesis yields homogeneously precipitated nanoparticles of NiO with average particle size of 4 nm on alumina nanofibers covered with NiAl2O4 nano-layer...
