Heat tolerance is a complex and economically important trait for catfish genetic breeding programs. With global climate change, it is becoming an increasingly important trait. To better understand the molecular basis of heat stress, a genome-wide association study (GWAS) was carried out using the 250 K catfish SNP array with interspecific backcross progenies, which derived from crossing female ...
The gonadotropin-releasing hormone (GnRH) receptor in catfish differs from its mammalian counterparts in showing a very low affinity for the hypothalamic GnRH form [i.e. catfish GnRH (cfGnRH)] and a very high affinity for the highly conserved mesencephalic GnRH, chicken GnRH-II (cGnRH-II). In the present study we investigated the molecular interactions between ligand and receptor involved in de...
We study spin and charge striped states at the half-filled high Landau level in the zero Zeeman energy limit using a HartreeFock approximation. It is shown that a ferromagnetic striped Hall state is more stable than the antiferromagnetic striped state or charge striped state. We calculate the collective excitations using the single mode approximation.
Chemokine receptor CXCR4, a member of the G protein-coupled receptor superfamily, binds selectively CXCL12. This protein plays many important roles in immunological as well as pathophysiological functions. In this study, we identified and characterized the channel catfish CXCR4 transcript. The full-length nucleic acid sequence of channel catfish CXCR4 cDNA comprised of 1994 nucleotides, includi...
In this study, the mechanism of resistance to striped stem borer was investigated in 10 rice genotypes and at different levels of nitrogen fertilizer. In addition, the relationship between some quantitative and qualitative traits of rice genotypes was evaluated with the resistance to striped stem borer.This experiment was conducted as split plot based on randomized complete block design with...
abstract background: the aims of this study were to assay the activity of adenosine deaminase (ada) in estrogen receptor positive (mcf-7) and negative (mda-mb468) breast cancer cell lines. methods: mda-mb468 and mcf-7 breast cancer cell lines were cultured in complete medium, striped serum with and without 0.0 1~-lm diethylstilbestrol (des), complete medium in the presence and absence of 111m t...
BACKGROUND The channel catfish (Ictalurus punctatus), a species native to North America, is one of the most important commercial freshwater fish in the world, especially in the United States' aquaculture industry. Since its introduction into China in 1984, both cultivation area and yield of this species have been dramatically increased such that China is now the leading producer of channel catf...
