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...

inhalation of pollens from different species of acacia is a common cause of respiratory allergy in tropical areas of the world. acacia farnesiana is commonly used as street trees in towns and ornamental shade trees in parks and gardens throughout arid and semi-arid regions of asia. this study aimed to produce and purify the a. farnesiana pollen profilin (aca f 2) and evaluate its nucleotide seq...

conclusions the pe gene was successfully cloned and confirmed by sequencing. finally, pe was obtained with high concentration. due to high homology and similarity among the pe gene from nthi atcc 49766 and other nthi strains in genbank, we believe that the protein is a universal antigen to be used as a vaccine design candidate and further studies to evaluate its immunogenicity is underway. mate...

Let B be a commutative algebra and A B-algebra (determined by an homomorphism ?:B?A). M. D. Staic introduced Hochschild like cohomology H•((A,B,?);A) called secondary cohomology, to describe the non-trivial deformations of A. J. Laubacher et al later obtained natural construction new chain complex C¯•(A,B,?) in process introducing cyclic (co)homology. In this paper, we establish connection betw...

We prove that every [Formula: see text]H-thin link has no text]-torsion for text] in its Khovanov homology.

Motivated by Akbulut-Larson's construction of Brieskorn spheres bounding rational homology 4-balls, we explore plumbed 3-manifolds that bound circles and use them to construct infinite families 3-spheres 4-balls. Some these are new examples integer but do not In particular, find torus bundles over the circle circles, provide a simple method for constructing more general show that, example, $-1$...
