the iranian persian chub is an endemic species of the family cyprinidae known only from few localities in drainages of southern iran. it was originally described in the genus pseudophoxinus as (pseudophoxinus persidis) and then petroleuciscus (as petroleuciscus persidis). in this study, we examined phylogenetic relationships of the iranian persian chubwith other relatives in the family cyprinid...

We have read with interest the recently published article by Hajiani et al.(1) in your journal. The distribution of HCV genotypes can enable clinicians to make better decisions for treatment of HCV-infected cases. In Iran, there is a low endemicity for HCV infections(2,3) the primary high risk groups for acquiring infection are patients on hemodialysis, those with hemophilia and thalassemia, an...

background: the values of embryonic stem cell and cloning are evident. production of clone from embryonic stem cells can be achieved by introduction of stem cell into a tetraploid blastocyst. tetraploid blastocyst can be produced in vitro by electrofusion of 2-cell embryos. objective: the aim of this study was to assess the effect of different voltages and durations on fusion rate of bovine 2-c...

209 Vitreoretinal surgery has experienced an explosion of advances in the last decade and a half. New advances in pars plana vitrectomy systems including small‐gauge instrumentation have provided many potential benefits to patients and surgeons. These include more efficient surgery; decreased postoperative inflammation leading to less pain and more patient comfort; improved cosmetic appearance ...

A linear 2-All-or-Nothing Transform can be considered as an invertible matrix with all 2 × 2 submatrices invertible. It is known [P. D’Arco, N. Nasr Esfahani and D.R. Stinson, Electron. J. Combin. 23(4) (2016), #P4.10] that there is no binary s×s matrix that satisfies these conditions, for s > 2. In this paper, different computational methods for generating invertible binary matrices with close...
