the polymerase chain reaction (pcr) was used to amplify a 578 bp fragment of the poxvirus 4b core protein. avipoxvirus (apv) specific dna was detected in all 10 different isolates (each of which had been isolated from an epidemic) isolated from chicken; canary and mynah were collected from tehran province. sequencing was performed for 2 isolates as representative and the nucleotide sequence sho...

Adenylate kinases (ADK) are ubiquitous enzymes that contribute to the homeostasis of adeninenucleotides in living cells. In this study, the cloning of a cDNA encoding an adenylate kinase from the filariaOnchocerca volvulus has been described. Using PCR technique, a 281 bp cDNA fragment encoding part ofan adenylate kinase was isolated from an O. volvulus cDNA library. Use of this fragment as a p...

Medicinal use of the opium poppy (Papaver somniferum L) has ancient history, but the isolation of morphine was not described until the early nineteenth century. Morphine is the most important alkaloid of opium poppy in the last 50 years. In the morphine pathway has been reported to generate morphine in this species, CODM has a crucial role as the gene coding the enzyme respons...

Background: Thrombopoietin is a glycoprotein produced by liver and kidney which is responsible for regulating the platelet production. Thrombopoietin is a key ligand with impact on regulating the self-renewal of Hematopoietic stem cells and the regulation of Megakaryocytes progenitors. Previous studies have indicated that only N-terminal domain of this protein has receptor promoting ability. Th...
