boophilus genus ticks are responsible for transferring some pathogens and reducing production factors in cattle. tropomysin (tpm) protein has actin regulator activity and playing important role in immune and allergic reactions. the main goal is to determine different aspects of phylogenetic, similarity, homology, structure and allergenicity of tpm protein. in prior study, we identified tpm by u...

The tenacity of a graph G, T(G), is dened by T(G) = min{[|S|+τ(G-S)]/[ω(G-S)]}, where the minimum is taken over all vertex cutsets S of G. We dene τ(G - S) to be the number of the vertices in the largest component of the graph G - S, and ω(G - S) be the number of components of G - S.In this paper a lower bound for the tenacity T(G) of a graph with genus γ(G) is obtained using the graph's connec...

Abstract Background and purpose: Paederus associated dermatitis has always been considered as a health problem in the northern of Iran. Since until now, the traditional method and some corticosteroids have been used in the treatment of Paederus dermatitis (PD) and no comprehensive studies have been carried out on the new method of treatment. Therefore, this study was aimed to compare the anti-i...

the genus syntretus foerster of the subfamily euphorinae (hym.: braconidae) is recorded from iran for the first time. the specimens were collected using malaise traps from different habitats of northern provinces during 2010 and 2011. two species, s. ocularis van achterberg & haeselbarth and s. xanthocephalus (marshall) were collected and identified. a brief discussion about diagnostic char...
