Bis(μ-5-carboxybenzene-1,3-dicarboxylato-κ2O1:O3)bis[(2,2'-bi-1H-imidazole-κ2N3,N3')zinc].

The title compound, [Zn(2)(C(9)H(4)O(6))(2)(C(6)H(6)N(4))(2)], consists of two Zn(II) ions, two 5-carboxybenzene-1,3-dicarboxylate (Hbtc(2-)) dianions and two 2,2'-bi-1H-imidazole (bimz) molecules. The Zn(II) centre is coordinated by two carboxylate O atoms from two Hbtc(2-) ligands and by two imidazole N atoms of a bimz ligand, in a distorted tetrahedral coordination geometry. Two neighbouring Zn(II) ions are bridged by a pair of Hbtc(2-) ligands, forming a discrete binuclear [Zn(2)(Hbtc)(2)(bimz)(2)] structure lying across an inversion centre.

Growth differences and dimorphic expression of growth hormone (GH) in female and male Cynoglossus semilaevis after male sexual maturation.

Half-smooth tongue sole, Cynoglossus semilaevis, is an ideal model to investigate the regulatory mechanisms of sexual growth dimorphism in fish species. The aim of the study was to investigate the effect of differential age of sexual maturity for females and males on growth and GH mRNA expression in C. semilaevis.

Growth differences and differential expression analysis of pituitary adenylate cyclase activating polypeptide (PACAP) and growth hormone-releasing hormone (GHRH) between the sexes in half-smooth tongue sole Cynoglossus semilaevis.

Pituitary adenylate cyclase activating polypeptide (PACAP) and growth hormone-releasing hormone (GHRH) are regulators of growth hormone secretion. In this article, we examined the difference in growth and mRNA expression of PACAP and GHRH between the sexes in half-smooth tongue sole, an important cultured fish species indicating sexually growth dimorphism in China. Firstly, a significant body weight difference between females and males was first observed at 7 months (P<0.

Poly[[aqua(mu(7)-ethylenediaminetetraacetato)dicadmium(II)] monohydrate].

The title compound, {[Cd(2)(C(10)H(12)N(2)O(8))(H(2)O)].H(2)O}(n), consists of two crystallographically independent Cd(II) cations, one ethylenediaminetetraacetate (edta) tetraanion, one coordinated water molecule and one solvent water molecule. The coordination of one of the Cd atoms, Cd1, is composed of five O atoms and two N atoms from two tetraanionic edta ligands in a distorted pentagonal-bipyramidal coordination geometry.

Novel noncentrosymmetric zinc coordination polymer containing an unusual zinc carboxylate-sulfonate substructure with a (10,3)-d topology and its second-harmonic-generation properties.

A novel 3D coordination polymer, Zn(2)(μ(2)-OH)(SIP)(DPP) (1), with mixed ligands of 5-sulfoisophthalate (SIP) and 1,3-di-4-pyridylpropane (DPP), has been hydrothermally synthesized and characterized. 1 contains an unusual 3D subnet with distorted (10,3)-d topology and left/right-handed helical channels. Second-harmonic-generation (SHG) measurements revealed that the material has a strong SHG response (∼2.

Polymorphisms in the 5' regulatory region of myostatin gene are associated with early growth traits in Yorkshire pigs.

Myostatin is a negative regulator of skeletal muscle mass. The present study cloned the 5' regulatory region of porcine myostatin gene, screened its polymorphisms and analyzed their associations with early growth traits in Yorkshire pigs. The results indicated that a fragment length polymorphism and a polymorphism concerning two nucleotide changes exist in the 5' regulatory region of porcine myostatin gene.

Production of cloned goats by nuclear transfer of cumulus cells and long-term cultured fetal fibroblast cells into abattoir-derived oocytes.

Dairy goats are ideal for the transgenic production of therapeutic recombinant proteins. The use of recombinant somatic cell lines for nuclear transfer (NT) allows the introduction of genes by transfection, increases the efficiency of transgenic animal production to 100%, and overcomes the problem of founder mosaicism. Although viable animals have been cloned via NT from somatic cells of 11 species, the efficiency has been extremely low.

[Identification and analysis of a novel microsatellite marker flanking porcine myostatin gene (MSTN)].

In animal breeding, microsatellite marker plays an important role in constructing genetic maps, QTL mapping and function analysis of structural genes. Myostatin, also known as GDF8, is a negative regulator of skeletal muscle mass and, in swine, it is evidenced to be related to birth weight and average daily gain from 60 kg to 100 kg of body weight. In present study, by subcloning and sequencing,we identified a novel microsatellite marker which is useful for fine QTL mapping for meat traits.

[Studies of BMPR-IB and BMP15 as candidate genes for fecundity in little tailed han sheep].

BMPR-IB gene which controls the fecundity of Booroola Merino and BMP15 gene which affects the ovulation of Invedale and Hanna were studied as candidate genes on the fecundity of Little Tailed Han Sheep, and their mutations and genetic effects were analyzed. The results showed that there was a same mutation in BMPR-IB gene (A746G) of Little Tailed Han Sheep as that of Booroola Merino. The BB mutation genotype was superior in prolific Little Tailed Han Sheep, and the ewes with genotype BB had 0.

Defective B-cell-negative selection and terminal differentiation in the ICF syndrome.

Immunodeficiency, centromeric region instability, and facial anomalies (ICF) syndrome is a rare autosomal recessive disease. Mutations in the DNA methyltransferase 3B (DNMT3B) gene are responsible for most ICF cases reported. We investigated the B-cell defects associated with agammaglobulinemia in this syndrome by analyzing primary B cells from 4 ICF patients.

[Research on Alu element inserted mutation in porcine FSH beta subunit gene].

The inserted fragment of FSH beta subunit gene in Laiwu pigs, an excellent local pig breed in North China, Duli pigs and Landrace pigs was amplified, cloned and sequenced. Sequence analysis showed that the length of the fragments inserted between +809 bp and +810 bp of the published sequences (D00621) were 275 bp, 277 bp and 274 bp in Laiwu, Duli and Landrace pigs, respectively. And the poly (A)s in these inserted fragments were 17, 19 and 16 adenines, respectively.

[Relationship of T-->A mutation in the promoter region of myostatin gene with growth traits in swine].

A T-->A mutation in the promoter region of porcine myostatin (MSTN) gene has been identified in previous work. Associations of the myostatin genotypes with growth traits are unknown in swine. The present study attempts to analyze the relationship of the mutation with the growth traits which included body weight at 60 d (BW60), average daily gain from 25 kg to 60 kg(ADG1), average daily gain from 60 kg to 100 kg (ADG2) and average daily gain from 25 kg to 100 kg (ADG).
