SayedGhahreman TaherianRecently Karzel and Taherian introduced the concept of a group with collinearity \((G, \kappa )\) and showed that for \(\alpha \in G \) the maps $$\begin{aligned} {{\tilde{\alpha }}}{:} \ G \rightarrow G ;~ \xi \mapsto \alpha \cdot \xi ^{1} \cdot \alpha \end{aligned}$$ of the corresponding reflection structure \((G , {\widetilde{G}} )\), where \( {\tilde{G}} := \{{{\tilde{\gamma }}} \  \ \gamma \in

Sonodynamic Therapy of Mice Breast Adenocarcinoma with HPMSN Iran. J. Sci. Technol. Trans. Sci. Pub Date : 20200527
Sahar Jafari, Majid Jadidi, Hadi Hasanzadeh, Tahere Khani, Reza Nasr, Vahid SemnaniSonodynamic therapy was appeared as a minimally invasive treatment that is based on the use of lowintensity ultrasound waves with a chemical agent that can be activated by ultrasound (US). The aim of this study was to evaluate the effect of hematoporphyrin (HP) and hematoporphyrinencapsulated mesoporous silica nanoparticle (HPMSN) with sonodynamic therapy in an animal model of breast adenocarcinoma

Swirling Flow of Jeffrey Fluid by a Spiraling Disk Iran. J. Sci. Technol. Trans. Sci. Pub Date : 20200527
Muhammad Noveel Sadiq, Muhammad Sajid, Muhammad Fahim, Tariq Javed, Nasir AliSwirling flows are frequently detected in nature such as combustion chambers, meteorological systems, turbomachines and their associated ducting, and cyclone separators. Due to the ability of rate type fluid to show time retardation and relaxation in their flow phenomenon. The current research is focused on the Jeffrey liquid flowing normally to a spiraling disk with constant rotation and radial stretching

In Vitro Effects of Cellular Phone Electromagnetic Fields at 940 MHz on the Structure and HalfLife of Recombinant Human Growth Hormone Iran. J. Sci. Technol. Trans. Sci. Pub Date : 20200525
Mehdi MohammadpourAghdam, Ahmad Molaeirad, Reza FarajiDana, Azadeh AziziThe biological effects of nonionizing electromagnetic radiation (EMF) are of high importance in biological and health studies. This study aimed to find out these effects on the structure and function of recombinant human growth hormone (rhGH). The rhGH was exposed to uniform mobile phone 940MHz EMFs for 45 min and then characterized by circular dichroism (CD), dynamic light scattering (DLS), zeta

Designing a SelfCleavable Construction Expressing Enterovirus 71 3C Protease Iran. J. Sci. Technol. Trans. Sci. Pub Date : 20200523
Mojtaba Rasti, Manoochehr Makvandi, Ali Teimoori, Nasrin Rastegarvand, Maryam Ghanbari3C protease is one of the most important proteases in enteroviruses, which is responsible for several cleavages of the viral polyprotein, leading to virus maturation. It has several harmful effects on host cells, such as the induction of caspasemediated apoptosis and the cleavage of various proteins like P53, TATAbinding protein (TBP), histone H3, octamerbinding protein 1 (OctI) and DNA polymerase

Simultaneous Preconcentration and Determination of Rhodamine B and Brilliant Blue Iran. J. Sci. Technol. Trans. Sci. Pub Date : 20200523
Abdullah Taner Bişgin, Yavuz Sürme, Mustafa Uçan, İbrahim NarinA simultaneous solidphase preconcentration and spectrophotometric determination method based on adsorption of rhodamine B (RB) and Brilliant Blue FCF (BB) synthetic dyes onto Chromosorb 108 resin was developed. Solution pH, sample, eluent flow rates and eluent type were optimized. RB and BB concentrations were determined at 556 and 630 nm, respectively. Matrix effects of interference components were
