Karyotype study was performed across 7 populations of 4 Rubus species growing in Iran. The results showed that the chromosome numbers of R. sanctus (2n=2x=14) diploid, R. caesius, and R. discolor were (2n=4x=28) tetraploids, R. persicus (2n=8x=56) octoploid. The chromosome numbers of R. discolor, and R. persicus were reported here for the first time. Karyotypic formula also varied between the s...
Background and Aims: Patients with Hyper-IgE syndrome suffer from fungal and bacterial infections, especially Candida albicans and Staphylococcus aureus. Due to the important role of T helper17 (Th17) lymphocytes in defense against fungal infections, the percentage of Th17 lymphocytes was studied in the patients with autosomal recessive hyper-IgE syndrome (AR-HIES). Materials and Methods: In...

Let $R$ be a prime ring, $I$ be any nonzero ideal of $R$ and $f:Irightarrow R$ be an additivemap. Then skew-Engel condition $langle... langle langle$$f(x),x^{n_1} rangle,x^{n_2} rangle ,...,x^{n_k} rangle=0$ implies that $f (x)=0$ $forall,xin I$ provided $2neq$ char $(R)>n_1+n_2+...+n_k, $ where $n_1,n_2,...,n_k$ are natural numbers. This extends some existing results. In the end, we also gener...
In this paper, we introduce tiling representations of Fibonacci p-numbers, which are generalizations the well-known and Narayana numbers, generalized in distance sense. We obtain p-numbers count number distinct ways to tile a 1 × n board using various r, r-ominoes from r = up p + 1. Moreover, product identities sum formulas these numbers with special subscripts given by interpretations that all...
