Apoptosis is a common pathway that finally mediated the killing functions of anticancer drugs, which is an important cause of multidrug resistance (MDR). The aim of this study was to investigate the potential benefit of combination therapy with magnetic nanoparticle of Fe(3)O(4) (MNP(Fe(3)O(4))) and 5-bromotetrandrin (BrTet). Analysis of the apoptosis percentage showed that combination of dauno...
The oxygen in hemoglobin is liberated by K(3)Fe(CN)(6) and not by KCN, that in hemocyanin by KCN and not by K(3)Fe(CN)(6), that in hemerythrin by both, and that in echinochrome by K(3)Fe(CN)(6) and not by KCN. The bearing of these results on the nature of the substances involved is discussed.
to determine the effects of drought stress and fe and zn spraying on two annual medics, namely, medicago polymorph cv serena and medicago scutellata cv comertial, a field experiment as a split factorial based on a randomized complete blockdesign in 3 replications in allborze agricultural research center, in karaj was conducted. spraying treatments include distilled water (control), fe, zn and f...
The magnetite (Fe3O4) nanoparticle and graphene oxide (GO) have become interesting materials due to their advanced applications. In this work, we investigated the fabrication of Fe3O4 nanoparticles (NPs) from iron sands and reduced graphene oxide (rGO) NPs from natural graphite. The core-shell fabrication of the Fe3O4/rGO was co...
A novel in situ method based on a liquid membrane templated self-assembly process is employed to modify carbon tube-in-tube nanostructures (TTCNTs) with Fe(2)O(3) nanoparticles. The as-obtained Fe(2)O(3) modified TTCNTs (Fe(2)O(3)/TTCNTs) nanocomposites are well constructed and the Fe(2)O(3) nanoparticles are well dispersed and decorated on the outer, inner and intramolecular surfaces of TTCNTs...
Gambogic acid (GA) has a significant anticancer effect on a wide variety of solid tumors. Recently, many nanoparticles have been introduced as drug-delivery systems to enhance the efficiency of anticancer drug delivery. The aim of this study was to investigate the potential benefit of combination therapy with GA and magnetic nanoparticles of Fe(3)O(4) (MNPs-Fe(3)O(4)). The proliferation of K562...
The combination of fluorescent nanoparticles and specific molecular probes appears to be a promising strategy for developing fluorescent nanoprobes. In this work, L-cysteine (L-Cys) capped Fe3O4@ZnO core-shell nanoparticles were synthesized for the highly selective detection of Fe(3+). The proposed nanoprobe shows excellent fluorescent property and high selectivity for Fe(3+) due to the binding...
In this study, Fe(3)O(4)/SiO(2)/TiO(2) photocatalyst was prepared via a sol-gel method, and Fe(3)O(4) particles were used as the core of the colloid. Diffraction peaks of Fe(3)O(4) crystals are not found by XRD characterization, indicating that Fe(3)O(4) particles are well encapsulated by SiO(2). FTIR characterization shows that diffraction peaks of Ti-O-Si chemical bonds become obvious when th...
این پروژه به سنتز و شناسایی و مطالعه خواص الکتروشیمیایی، اسپکتروسکوپی سه کمپلکس کاتیونی- آنیونی تهیه شده بر پایه عناصر واسطهfe وzn می پردازد. کمپلکس های[fe(opd)3]4[zn(cn)6]3 ، [zn(bpy)2(phen)][fe(dipic)2]2.4h2o و[zn(phen)2(opd)][fe(dipic)2]2.4h2o سنتز و مورد مطالعه الکتروشیمی قرار گرفتند. طیف ir کمپلکس 3 [fe(opd)3]4[zn(scn)6] پیک قوی مربوط به ارتعاش گروه سیانید را در cm-1 2066 نشان می دهد. طیف...
The arrangement graph An,k, which is a generalization of the star graph (n − k = 1), presents more flexibility than the star graph in adjusting the major design parameters: number of nodes, degree, and diameter. Previously, the arrangement graph has proved Hamiltonian. In this paper, we further show that the arrangement graph remains Hamiltonian even if it is faulty. Let Fe and Fv denote ...
