In spite of broad improvements in construction technology, cement is still stayed as binding material for construction purposes. Cement industries are the main sources for the contribution of carbon dioxide (co2) into the atmosphere. So, there is a need to use new materials as binders (green binders) in substitute for cement, which leads to reducing the production of cement. In this study, fly ...

multiple sclerosis (ms) is an autoimmune disease of central nervous system. since different types of immune cells are involved in ms pathogenesis, in this study we aimed to evaluate serum levels of several immunological components including soluble cd4 (scd4), scd8, scd163, and immunoglobulins as markers of activity of t-cells, macrophages, and b-cells in different types of ms. serum levels of ...

Abstract Alkali-activated systems belong to the group of alternative inorganic binders in which binder properties are dictated by both aluminosilicate precursor and alkaline activator. In this work, blast furnace slag three different activators, namely sodium hydroxide, water glass, carbonate, were selected. An innovative mixture design based on same concentration alkali (Na + ) 4 mol/dm 3 for ...

Alkali-activated slag is commonly used as a cement substitute to reduce the environmental footprint of construction materials. Nonetheless, use significant amount alkaline activators, such sodium silicate or hydroxide, can be detrimental in terms global warming potential impact. The aim this work complementary activators partial replacement and therefore activated binder. Calcium calcium carbon...

Proteasomes degrade a multitude of protein substrates in the cytosol and nucleus, and thereby are essential for many aspects of cellular function. Because the proteolytic sites are sequestered in a closed barrel-shaped structure, activators are required to facilitate substrate access. Structural and biochemical studies of two activator families, 11S and Blm10, have provided insights to proteaso...

The Drosophila melanogaster genome contains 5 genes that code for soluble guanylyl cyclase subunits. Two of these genes code for subunits, Gycalpha-99B and Gycbeta-100B, which form a conventional NO-sensitive guanylyl cyclase and the other three code for atypical subunits, Gyc-88E, Gyc-89Da and Gyc-89Db. The properties and distribution of Gyc-88E and Gyc-89Db have previously been described and ...

Purified prothrombin can be converted into thrombin in different ways (2), namely, by the use of biological activators, by the action of high concentrations of sodium citrate, and by treatment with trypsin. Biological activation of prothrombin requires lipoprotein tissue-factor(s) that have prothrombin-converting or thromboplastic activity, protein serum-factor(s) which augment thromboplastic a...
