Effect of exogenous thermophilic biocontrol agent inoculum on the high temperature chicken manure composting.

Introduction: Aerobic composting is an effective method for utilizing chicken manure. However, its low carbon to nitrogen (C/N) ratio leads to slow heating and short high-temperature phases, which reduce composting efficiency and product quality.

Methods: To address this issue, splinted mushroom cultivation residues were added to adjust the C/N ratio, and exogenous thermophilic composting strains were introduced to increase composting temperature.

Genome-Wide Identified MADS-Box Genes in 'Plena' and Theirs Roles in Double-Flower Development.

The MADS-box gene family plays key roles in flower induction, floral initiation, and floral morphogenesis in flowering plants. To understand their functions in the double-flower formation of 'Plena' (hereafter referred to as PCP), which is an excellent flowering cherry cultivar, we performed genome-wide identification of the MADS-box gene family. In this study, 71 MADS-box genes were identified and grouped into the Mα, Mβ, Mγ and MIKC subfamilies according to their structures and phylogenetic relationships.

Genome assembly, resequencing and genome-wide association analyses provide novel insights into the origin, evolution and flower colour variations of flowering cherry.

Flowering cherry is a very popular species around the world. High-quality genome resources for different elite cultivars are needed, and the understanding of their origins and the regulation of key ornamental traits are limited for this tree. Here, a high-quality chromosome-scale genome of Prunus campanulata 'Plena' (PCP), which is a native and elite flowering cherry cultivar in China, was generated.

CD200Fc attenuates inflammatory responses and maintains barrier function by suppressing NF-κB pathway in cigarette smoke extract induced endothelial cells.

Background: Recent evidence suggests that CD200 fusion protein (CD200Fc), a CD200R1 agonist may attenuate inflammatory responses in autoimmune diseases and neuro-degeneration. While, little is known about the function of CD200Fc in cigarette smoke extract (CSE)-induced mouse Cardiac Microvascular Endothelial Cells (mCMECs). The present study was designed to elucidate the effects of CD200Fc on CSE-induced vascular endothelial barrier (VEB) dysfunction and inflammatory responses, which is a highly clinically relevant model of smoking related cardiovascular diseases.

Delivery of selective agents via time-delayed release tablets improves recovery of Listeria monocytogenes injured by acid and nitrite.

Listeria selective enrichment media are designed to enhance the isolation of the organism and increase the chances of detection. Drawbacks include the requirements for prolonged sample incubation (48 to 72 h) and manual addition of selective agents, which may be a source of contamination. Modified Listeria recovery broth (mLRB) is a proprietary enrichment medium formulated to facilitate the recovery of injured cells; its selective agents are incorporated into a format that allows delayed release until 6 h of incubation.

Dimeric 1,3-propanediaminetetraacetato lanthanides as the precursors of catalysts for the oxidative coupling of methane.

From neutral solutions, dimeric 1,3-propanediaminetetraacetato lanthanides (NH4)2[Ln2(1,3-pdta)2(H2O)4]·8H2O [Ln = La, 1; Ce, 2] and K2[Ln2(1,3-pdta)2(H2O)4]·11H2O [Ln = La, 3; Ce, 4] (1,3-H4pdta = 1,3-propanediaminetetraacetic acid, C11H18N2O8) were isolated in high yields. The reaction of excess strontium nitrate with 1 resulted in the formation of a two dimensional coordination polymer [La2(1,3-pdta)2(H2O)4]n·[Sr2(H2O)6]n·[La2(1,3-pdta)2(H2O)2]n·18nH2O (5) at 70 °C. Complexes 1-4 show a similar central molecular structure.

Mechanistic aspects of photo-induced formation of peroxide ions on the surface of cubic Ln2O3 (Ln = Nd, Sm, Gd) under oxygen.

The photo-induced formation of peroxide ions on the surface of cubic Ln2O3 (Ln = Nd, Sm, Gd) was studied by in situ microprobe Raman spectroscopy using a 325 nm laser as excitation source. It was found that the Raman bands of peroxide ions at 833-843 cm(-1) began to grow at the expense of the Ln(3+)-O(2-) bands at 333-359 cm(-1) when the Ln2O3 samples under O2 were continuously irradiated with a focused 325 nm laser beam at temperatures between 25-150 °C. The intensity of the peroxide Raman band was found to increase with increasing O2 partial pressure, whereas no peroxide band was detected on the Ln2O3 under N2 as well as on the samples first irradiated with laser under Ar or N2 followed by exposure to O2 in the dark.

In situ Raman and pulse reaction study on the partial oxidation of methane to synthesis gas over a Pt/Al2O3 catalyst.

Catalytic partial oxidation of methane (POM) to synthesis gas (syngas) over Pt/Al(2)O(3) was investigated by in situ microprobe Raman and pulse reaction methods with attention focused on the mechanism of syngas formation in the oxidation zone (i.e., the catalyst zone in which O(2) was still available in the reaction feed).

pH- and mol-ratio dependent formation of zinc(II) coordination polymers with iminodiacetic acid: synthesis, spectroscpic, crystal structure and thermal studies.

Three novel zinc coordination polymers (NH(4))(n)[Zn(Hida)Cl(2)](n) (1), [Zn(ida)(H(2)O)(2)](n) (2), [Zn(Hida)(2)](n)·4nH(2)O (3) (H(2)ida = iminodiacetic acid) and a monomeric complex [Zn(ida)(phen)(H(2)O)]·2H(2)O (4) (phen=1,10-phenanthroline) have been synthesized and characterized by X-ray diffraction methods. 1 and 2 form one-dimensional (1-D) chain structures, whereas 3 exhibits a three-dimensional (3-D) diamondoid framework with an open channel. The mononuclear complex 4 is extended into a 3-D supramolecular architecture through hydrogen bonds and π-π stacking.

Metal-organic frameworks constructed from monomeric, dimeric and trimeric phenanthroline citrate zinc building units.

Adduct of mononuclear and dinuclear citrate zinc complex [Zn(Hcit)(phen)(HO)][Zn(Hcit)(phen)(HO)]·13.5HO () and its aggregate [Zn(Hcit)(phen)]·14nHO () (Hcit = citric acid, phen = 1,10-phenanthroline) were synthesized in weak acidic solutions. The former was obtained from the reaction of zinc nitrate, citric acid and phenanthroline in a molar ratio of 3 : 2 : 3, while a slightly excess of phenanthroline results in the formation of the polymeric product in a molar ratio of 3 : 2 : 4.

Metal ion-mediated polymer superquenching for highly sensitive detection of kinase and phosphatase activities.

An assay technology for high-throughput screening of kinase and phosphatase activities is introduced. The format is based upon superquenching of fluorescent-conjugated polymers by dye-labeled kinase/phosphatase peptide substrates. The sensor platform is composed of highly fluorescent-conjugated polyelectrolytes colocated with the phosphate coordinating metal ion gallium on microspheres.

Applications of fluorescent polymer superquenching to high throughput screening assays for protein kinases.

Protein kinases are involved in the regulation of cellular metabolism, growth, differentiation, and proliferation. Aberrations in their function can lead to diseases such as cancer and inflammation. Protein kinases are therefore possible targets for drug therapies.

Fluorescent-conjugated polymer superquenching facilitates highly sensitive detection of proteases.

Sensor formats have been developed for detecting the activity of proteolytic enzymes based on fluorescent conjugated polymer superquenching. These sensors employ a reactive peptide sequence within a tether linking a quencher to a biotin. The peptide binds to sensors containing colocated biotin-binding protein and fluorescent polymer by means of biotin-biotin binding protein interactions, resulting in a strong quenching of polymer fluorescence.
