Substituting natural aggregates in the green roof substrate and drainage layers with lightweight artificial recycled coarse materials is an eco-friendly alternative for applying lower load to rooftops preserving resources. However, a lack of precise understanding thermal resistance, water passing ability, holding capacity materials, including has raised demand measuring their Rc-value, permeabi...

The origin of the eukaryotic cell is one of the most important transitions in the history of life. However, the emergence and early evolution of eukaryotes remains poorly understood. Recent data have shown that the last eukaryotic common ancestor (LECA) was much more complex than previously thought. The LECA already had the genetic machinery encoding the endomembrane apparatus, spliceosome, nuc...

BACKGROUND The Nuclear Pore Complex (NPC) facilitates molecular trafficking between nucleus and cytoplasm and is an integral feature of the eukaryote cell. It exhibits eight-fold rotational symmetry and is comprised of approximately 30 nucleoporins (Nups) in different stoichiometries. Nups are broadly conserved between yeast, vertebrates and plants, but few have been identified among other majo...

background: water filtration units have been faced problems in water turbidity removal related to their media, which is determined by qualitative indices. moreover, current qualitative indices such as turbidity and escaping particle number could not precisely determine the efficiency of the media in water filtration, so defining new indices is essential. in this study, the efficiency of anthrac...

The concept that leukocyte-endothelial cell adhesion (LECA) is a major determinant of the tissue injury elicited by ischemia/reperfusion (I/R) is largely based on studies employing adhesion molecule-specific monoclonal antibodies. The objective of this study was to assess the contribution of LECA to I/R injury using mutant mice (all on a C57B1 background) that are deficient in either intracellu...

Intravital microscopic techniques were used to examine the mechanisms underlying bradykinin-induced leukocyte/endothelial cell adhesive interactions (LECA) and venular protein leakage (VPL) in single postcapillary venules of the rat mesentery. The effects of bradykinin superfusion to increase LECA and VPL were prevented by coincident topical application of either a bradykinin-B(2) receptor anta...

Pseudomonas aeruginosa (PA) and Burkholderia ambifaria (BA) are two opportunistic Gram negative bacteria and major infectious agents involved in lung infection of cystic fibrosis patients. Both bacteria can develop resistance to conventional antibiotherapies. An alternative strategy consists of targeting virulence factors in particular lectins with high affinity ligands such as multivalent glyc...

In the present study, lightweight expanded clay aggregate (LECA) coated with iron oxide was investigated as a low cost sorbent to remove  from wastewater. Iron oxide coated LECA (IOCL) as a new sorbent was tested for its efficiency as  sorbent using operational parameters such as contact time, the initial pH of the solutions, and sorbent dosage concentration in batch systems. The adsorption cha...
