administering growth hormone increases growth rate of cultured fish. the aim of this study was isolation and synthesize of persian sturgeon gh cdna. the total rna was extracted from pituitary gland of persian sturgeon and cdna was synthesized. the full-length cdna sequence of persian sturgeon contains a 645 nucleotide open reading frame, which encoding a 214 amino acid residues. the position of...

Chronic inflammation can associate with autoreactive immune responses, including CD4(+) T cell responses to self-Ags. In this paper, we show that the adipocyte-derived proinflammatory hormone leptin can affect the survival and proliferation of autoreactive CD4(+) T cells in experimental autoimmune encephalomyelitis, an animal model of human multiple sclerosis. We found that myelin olygodendrocy...

We have previously demonstrated that the 21-residue peptide pMOG(35-55) from myelin oligodendrocyte glycoprotein (MOG) contains an antigenic epitope that activates CD8(+) encephalitogenic T cells in C57BL/6 (B6) mice. To identify the core encephalitogenic epitope of CD8(+) MOG-specific T cells, we have prepared a panel of highly purified peptides of varying lengths, which span the entire length...

conclusions the results of the current study suggested that spinal anesthesia plus intravenous patient-controlled analgesia have the most favorable cardiac effects regarding postoperative levels of pro-bnp. results there was no difference between three groups for basic characteristics and variables and baseline pro-bnp levels; however, postoperative pro-bnp levels in groups a, b, and c were res...

Thrombin cleaves its G-protein-linked seven-transmembrane domain receptor, thereby releasing a 41-aa peptide and generating a new amino terminus that acts as a tethered ligand for the receptor. Peptides corresponding to the new amino terminal end of the proteolyzed seven-transmembrane domain thrombin receptor [TR42-55, SFLLRNPNDKYEPF, also known as TRAP (thrombin receptor-activating peptide)], ...

Several peptides derived from the gastrin-predicted preprohormone sequence were isolated from a human gastrinoma by gel permeation, anion exchange, and reverse phase chromatography. The peptides were identified and characterized structurally by a combination of radioimmunoassays, mass spectral analysis, and microsequence analysis. The largest peptide, progastrin-(1-35) (cryptagastrin), extends ...

We determined cardiovascular and neurohormonal responses to intracerebroventricular administration of human cocaine- and amphetamine-regulated transcript (CART) peptide 55-102 in conscious rabbits. Intracerebroventricular injection of CART 55-102 elicited dose-related increases in mean arterial pressure and renal sympathetic nerve activity. Peak values of mean arterial pressure and renal sympat...

Chicken egg yolk immunoglobulin (IgY) is a functional substitute for mammalian IgG for antigen detection. Traditional IgY purification methods involve multi-step procedures resulting in low purity and recovery of IgY. In this study, we developed a simple IgY purification system using IgY-specific peptides identified by T7 phage display technology. From disulfide-constrained random peptide libra...

The studies reported here were undertaken to clarify the cellular mechanism of the hypothalamic tripeptide, thyrotropin-releasing hormone (TRH), in clonal, hormone-responsive GH pituitary cells and to assess the possibility of a role for cyclic AMP as a mediator of TRH action. We investigated patterns of protein phosphorylation by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and au...
