background: the rh antigens are expressed as parts of a protein complex in the rbc membrane. this complex is a tetramer, consisting of two molecules of rhag and two molecules of rh proteins. to express rhd in rbc membrane, expression of rhag is essential. this co-expression only occurs in the erythroid lineage. k562 cell line has an erythroid lineage. materials and methods: cord blood was used ...
Extensive urbanization has greatly raised the demand for cleaner coal- and petroleum-derived fuels. Mainly composed of methane, natural gas represents a promising alternative for this purpose, making its storage a significant topic. In the present research, deposition of methane molecules in C60 fullerene was investigated through a combined approach wherein density functional based tight bindin...
Background & Aims: The overall goal of utilizing nanotubes in drug delivery is to treat a disease effectively with minimum side effects and control the drug release rate. With common methods of taking the medication, such as orally and intravenously, the drug is distributed throughout the body, and the whole body is affected by the drug, and adverse side effects occur. With the development of n...
Kaj-Rostam Abad, Dashtak and Do Ab salt domes are located around Ardal and Farsoun village. This area is situated in High Zagros range (Chaharmahal and Bakhtiary Province). The study area is composed of Lower Cambrian volcano sedimentary complex including basalt, basaltic andesite, andesite, trachyte, pyroclastics, evaporite rocks and Precambrian sedimentary units. According to the mineralogica...
The reaction of CH₃NH₂ with O₂ on the singlet potential energy surfaces (PES) was carried out using the B3LYP, CCSD(T) and G3B3 theoretical approaches along with 6-311++G(3df,3pd) basis set. The suggested mechanism for the title reaction consists of one pre-reactive complex. From the pre-reactive complex, nine types of products, CH2NH+H2O2, CH3NH+OOH,...
The redox properties of sulfite ion has been examind using cyclic voltammetry in acetonitrile solvent at the surface of gold, pelatin and glassy carbon electrodes. It has bben found tha, sulfite ion exhibits two electron oxidation peak with EC’ mechanism. A novel chemically modified electrode containing Prussian blue complex and multi wall carbon nanotubes (MWCNs) was achieved on the surface of...
today, using new and renewable energy sources to replace fossil fuels is greatly expanded. the solar cells are devices that convert solar energy to electrical energy. solar cells based on organic materials, especially proteins, are one of these solar cells. for example, bacteriorhodopsin (br) which is one of the membrane proteins in halobacterium salinarum could be used in solar cells and parti...
this study investigated the effects of manipulating the cognitive complexity of tasks along +/- few elements and the time limits on l2 learners writing performance. to conduct the study, 60 iranian efl learners with two levels of proficiency, low and high intermediate, were selected and assigned to three groups based on the time devoted to task completion. the participants performed both a simp...
a novel chemically modified electrode containing prussian blue complex was achieved on the surface of glass carbon electrode by sol-gel technique. the electrochemical behavior of modified electrode was characterized by cyclic voltammetry in detail. the film electrode obtained was very stable and exhibited electrocatalytic response for oxidation of nitrite. results showed at bare gc electrode, a...
