High repetitive arginine in the anterior of PCV3 capsid protein is a severe obstacle for its expression in E. coli.

Porcine circovirus type 3 (PCV3) is a novel circovirus identified in sows with PDNS-like clinical signs and reproductive failure. The capsid protein (CAP) of PCV3 is expected to be an effective vaccine candidate. Here, we expressed the original capsid protein, truncated capsid protein without anterior highly repetitive arginine (ΔCAP) and their codon-optimized counterparts in E.

Effects of altrenogest on reproductive performance of gilts and sows: A meta-analysis.

Altrenogest is a synthetic progestogen that allows for synchronization of the time of estrus in swine. Its effect on reproductive performance, however, is inconsistent due to conflicting data in the scientific literature. A meta-analysis of published data, therefore, was performed to determine whether altrenogest affects gilt and sow reproductive performance.

The effects of melamine with or without cyanuric acid on immune function in ovalbumin-sensitized mice.

Melamine is commonly used in the chemical industry, and it has been found to exist on food processing equipment and utensils. Previous investigations suggested that melamine alone or its combination with cyanuric acid appears to be toxic to immune system in animals. The objective of this study is to investigate the potential effects of melamine with or without cyanuric acid on immune function in ovalbumin- sensitized mice.

The effects of melamine on humoral immunity with or without cyanuric acid in mice.

Melamine is an industrial chemical with high nitrogen content. When added to the pet food and milk it can falsely elevate the apparent protein concentration readings. Cyanuric acid related structurally to melamine has a strong mutual affinity with melamine.

The toxic effects of melamine on spleen lymphocytes with or without cyanuric acid in mice.

Melamine is an organic nitrogenous compound whose acute toxicity was generally thought to be low in animals. In the present work, we investigated the potential cytotoxic effects of melamine on spleen lymphocytes in mice. In the treated group, morphological changes were observed in cultured lymphocytes in vitro.

The reproductive toxicity of melamine in the absence and presence of cyanuric acid in male mice.

Melamine, a chemical compound, was used widely in the manufacture of amino resins and plastics. Cyanuric acid related structurally to melamine was used as a water stabilizer in swimming pools. The combination of melamine and cyanuric acid was thought to be responsible for renal impairment in mammals.

Diaquabis[5-(pyrazin-2-yl-kappaN(1))-1H-tetrazolato-kappaN(1)]manganese(II) and diaquabis[5-(pyrazin-2-yl-kappaN(1))-1H-tetrazolato-kappaN(1)]zinc(II).

The two new title complexes, [Mn(C5H3N6)2(H2O)2] and [Zn(C5H3N6)2(H2O)2], are isomorphous. In both compounds, the metal atom is located on an inversion center and is coordinated by four N atoms from two 5-(pyrazin-2-yl)-1H-tetrazolate anions in the basal plane and by two O atoms of water ligands in the apical positions to form a distorted octahedral geometry. Intermolecular hydrogen-bond interactions between the uncoordinated N atoms of the tetrazolate anions and the H atoms of the water molecules lead to the formation of a three-dimensional network.
