Structural basis of haptoglobin-haemoglobin scavenging by CD163 by Zhou, X

“…Indeed, biophysical assays show that calcium ions are critical for ligand binding. Mutational studies demonstrate that while monomeric CD163 can scavenge the multimeric Hp(2-2)Hb, uptake of the dimeric Hp(1-1)Hb and Hb is impaired compared to the wild-type receptor, suggesting that receptor multimerisation evolved to facilitate uptake of lower affinity ligands. …”

Experimental study on durability properties of kenaf fibre-reinforced geopolymer concrete by Noor Abbas, Al-Ghazali, Abdul Aziz, Farah Nora Aznieta, Abdan, Khalina, Mohd Nasir, Noor Azline, Fahim Huseien, Ghasan

“…Hence, this article aims to understand the performance of kenaf fibre-reinforced geopolymer concrete (KFRGC) in terms of water absorption, porosity, sorptivity, water penetration, and resistance against chloride ions penetration and chemical attacks. The results showed that the addition of KF increased the porosity of the geopolymer, thus increasing the water absorption-related properties. …”
