Investigation of the exact spin channels in laser-induced spin dynamics in two mononuclear Cu(II) complexes.

In the quest to harness the potential of nanospintronic applications, we analyze and investigate the spin channels for the ultrafast spin dynamics in mononuclear Cu(tdp)Cl (Cutdp) and Cu(tdp)Cl·MeCN (Cutdp·MeCN) using a high-level many-body theory. In that spirit, we select two slightly different polymerizations arising from one parent complex. We establish the difference in magnetic behavior between the two complexes which arises solely from the geometrical differences.

Ginsenoside Rg1 and Re alleviates inflammatory responses and oxidative stress of broiler chicks challenged by lipopolysaccharide.

Previous study showed that ginsenoside Rg1 (Rg1) and ginsenoside Re (Re) alleviated growth inhibition of broiler chicks with immune stress. The aim of this study was to investigate the effect of Rg1 and Re on inflammatory responses, oxidative stress, and apoptosis in liver of broilers with immune stress induced by lipopolysaccharide (LPS). Forty broiler chicks were randomly divided into 4 groups, each group consisting of 10 chickens.

Slow magnetic relaxation in high-coordinate Co(II) and Fe(II) compounds bearing neutral tetradentate ligands.

The first-row transition metal compounds, [M(L1)](ClO) (M = Ni (1); Co (2)), have been prepared by treatment of a neutral tetradentate ligand (L1 = ,-dibutyl-1,10-phenanthroline-2,9-dicarboxamide) with metal perchlorate salts in MeOH. Both compounds have been structurally characterized by X-ray crystallography and it was found that the coordination numbers are 6 and 7, respectively. The reaction of 6,6'-bis(2-butyl-tetrazol-5-yl)-2,2'-bipyridine (L2) with hydrated Fe(ClO) afforded a 8-coordinate Fe(II) compound, [Fe(L2)](ClO) (3); however its reaction with hydrated Co(ClO) resulted in 6-coordinate [Co(L2)](ClO).

Duck Complement Factor H Binds to Outer Membrane Protein Omp24 of .

The resistance to serum complement-mediated killing is a vital virulence property of microbial pathogens. Complement factor H (FH) is a key negative regulator of the complement alternative pathway (AP) that prevents formation and accelerates the decay of AP C3 convertase and acts as a cofactor in the inactivation of C3b. Pathogens can recruit host FH through their surface proteins to escape the clearance of the complement system.

Slow magnetic relaxation in structurally similar mononuclear 8-coordinate Fe(II) and Fe(III) compounds.

A pair of structurally-similar and stable 8-coordinate high-spin Fe(ii) and Fe(iii) compounds have been obtained. Both compounds exhibit field-induced slow magnetic relaxation behaviour. The Fe(iii) compound represents the first example of 8-coordinate Fe(iii) single-molecule magnets (SMM).

[Cloning and expression of duck C4BPα and verification of its interaction with Riemerella anatipestifer].

To study the interaction between C4b-binding protein (C4BP) and Riemerella anatipestifer (RA), we cloned duck C4BPα, conducted prokaryotic expression and prepared the polyclonal antibody by immunizing mice. Then indirect immunofluorescence assay and dot blotting hybridization assay were used to verify the interaction between C4BP and RA. The full length of duck C4BPα nucleotide sequence was 1 230 bp, with the highest similarity to chicken C4BPα (82.

Molybdate-Tellurite Compounds with Capped-Kagomé Spin-Lattices.

Three new molybdate-tellurites, KM(TeO)(MoO)(OH) (M = Ni and Co) and (NH)Cu(TeO)(MoO)(OH), have been successfully synthesized by conventional hydrothermal method. Due to the influence of the Jahn-Teller effect, these compounds crystallize in different space groups of rhombohedral 3̅, monoclinic 2/ and triclinic 1̅ for Ni-, Co-, and Cu-analogues, respectively. The topological arrangements of magnetic ions in these compounds show that deficient capped-kagomé spin-lattices with kagomé positions exhibit different 1/6 depletion.

Detection and Molecular Characterization of Two Genotypes of Goose Parvoviruses Isolated from Growing Period Geese and Cherry Valley Ducks in China.

Goose parvovirus (GPV) is the etiologic pathogen of Derzsy's disease, causing great economic losses in the waterfowl industry. A novel GPV-related virus (NGPV), which caused short beak and dwarfism syndrome, has occurred in China since 2015. In this study, two GPV strains (RC45 and RC70) were isolated from diseased growing period geese (45 days old and 70 days old), and one NGPV strain GXN45 was isolated from a 45-day-old Cherry Valley duck in China.

Targeted replacement: systematic studies of dodecanuclear {MLn} coordination clusters (M = Cr, Co; Ln = Dy, Y).

Three dodecanuclear 3d-4f coordination clusters, [CrIII6LnIII6(μ3-OH)8(tbdea)6(C6H5COO)16]·2H2O (Ln = Dy (1), Y (2)) and [CoIII6DyIII6(μ3-OH)8(nbdea)6(m-CH3C6H4COO)16]·2H2O·2CH3CN (3), have been synthesized under solvothermal conditions and characterized. Single-crystal X-ray diffraction analysis revealed that all three compounds possess an analogous {MIII6LnIII6} core (M = Cr, Co; Ln = Dy, Y) and dc magnetic susceptibility studies indicated that the magnetic exchange couplings between DyIII ions are dominant antiferromagnetic, while the CrIII-DyIII interactions are weakly ferromagnetic. Furthermore, the ac magnetic susceptibility measurements showed that both CrIII6DyIII6 compound 1 and CoIIi6DyIII6 compound 3 containing highly anisotropic DyIII ions displayed single-molecule magnetic (SMM) behavior with the energy barrier Ueff increasing from 12.

Synthesis and magnetic properties of two isostructural fluorophosphates BaMPOF (M = Cu, Co) with a tunnel structure.

Two fluorophosphates, BaMPOF (M = Cu, Co), have been synthesized by a conventional hydrothermal method, and they crystallize in the orthorhombic system with the space group P222, exhibiting a tunnel structure built by distorted MOF square-pyramids and PO tetrahedra. The magnetic behaviors of the two compounds are investigated by means of magnetic susceptibility, magnetization, and heat capacity measurements. The results indicate that BaCuPOF exhibits a paramagnetic behavior down to 2 K, while BaCoPOF undergoes long-range antiferromagnetic ordering at 11.

Synthesis, structure, and magnetic properties of new layered phosphate halides SrCu(PO)X·8HO (X = Cl, Br) with a crown-like building unit.

Two new compounds SrCu(PO)X·8HO (X = Cl and Br) are synthesized by a conventional hydrothermal method. SrCu(PO)Cl·8HO crystallizes in the tetragonal system with a space group of P422, while SrCu(PO)Br·8HO crystallizes in the space group P4/nmm, which are found to have a similar framework of layered structure, in which the crown-like {Cu(PO)X} building units connect to each other forming a 2D corrugated sheet with vacancies, while the Sr cations are located along the vacancies. The spin lattice of two compounds built by Cu ions shows a new type of corrugated square.

Riemerella anatipestifer extracellular protease S blocks complement activation via the classical and lectin pathways.

Riemerella anatipestifer (RA) is the causative agent of infectious serositis in ducklings and other avian species. It is difficult to control the disease due to its 21 serotypes, poor cross-protection, and bacterial resistance to antimicrobial agents. The complement system is an important component of the innate immune system.

A single molecule magnet to single molecule magnet transformation via a solvothermal process: Fe4Dy2 → Fe6Dy3.

Two series of heterometallic Fe(III)-Ln(III) compounds, [FeLn(μ3-OH)2(mdea)4(m-NO2C6H4COO)8]·3MeCN where Ln = Y (1) and Dy (2) and [FeLn(μ4-O)3(μ3-O)(mdea)5(m-NO2C6H4COO)9]·3MeCN where Ln = Y (3) and Dy (4), were synthesized. Compounds 1 and 2 were obtained under ambient conditions, whereas 3 and 4 were obtained via a solvothermal transformation process by heating 1 or 2 at 120 °C in MeCN. The magnetic properties of all four compounds have been measured and show that compounds 2 and 4 containing Dy(III) ions exhibit slow relaxation of magnetization characteristic of Single Molecule Magnetic (SMM) behaviour.

Developing a "highway code" to steer the structural and electronic properties of Fe(III)/Dy(III) coordination clusters.

In the recently established field of 3d/4f coordination cluster (CC) chemistry several burning questions still need to be addressed. It is clear that combining 3d and 4f metal ions within a coordination cluster core has the potential to lead to electronic structures that will be very difficult to describe but can also be extremely interesting. Furthermore, understanding why certain core topologies seem to be favored is difficult to predict.
