background: the cultivation of saffron is expanding through the southeast of iran, and allergy to saffron pollen occurs in workers involved in processing this plant. we aimed to clone, sequence and express a major allergen involved in saffron pollen allergy, and to compare the recombinant with the natural allergen. methods: the n-terminal amino acid sequence of cro s 1, an allergen from saffron...

background: breast cancer is one of the most prevalent malignancies among women in various countries. her2 overexpression, which is due to different reasons, occurs in 20-30% of breast cancers. her2 gene encodes an 185kda transmembrane glycoprotein with 1255 amino acids. this active product triggers downstream intracellular signaling pathways inducing cell proliferation and cell survival. these...

Abiotic stresses, such as temperature (heat and cold), salinity, drought negatively affect plant productivity; hence, the molecular responses of abiotic stresses need to be investigated. Numerous genetic engineering studies have made substantial contributions revealed that are key factors associated with production losses in plants. In response altered expression patterns miRNAs been reported, ...

in this paper, load and buckling mode of a smart column are presented. the theoretical model is a three-layer piezoelectric composite beam that behaves as an axial actuating mechanism. this actuator consists of an elastic core sandwiched between two piezoelectric active outer layers. the piezoelectric layers are polarized transversely, i.e., the polarization vector is parallel to the applied el...

Aspartic proteases are a relatively small group of enzymes which express in various nematodes including Onchocerca volvulus. An estimation of the gene copy number corresponding to the OV7A clone, which contains a cDNA insert encoding approximately two-thirds of the entire coding sequence of aspartic protease of O. volvulus, was made by slot blot analysis in a closely related species O. gibsonig...

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...
