In silico probing Ca2+ and Zn2+ permeable transmembrane 4Aβ1−42 barrel

Alzheimer’s disease (AD) is known as one of the most popular forms of dementia affecting numerous people worldwide. The Amyloid beta (Aβ) peptides form oligomeric conformations that cause the intracellular Ca2+ and Zn2+ abnormality leading to the death of neuron cells. The failure of AD therapy targeting Aβ oligomers probably caused by misunderstanding the ions transport through transmembrane Aβ (tmAβ) ion-like channel since Aβ oligomers transiently exist in a mixture environment involving various order of Aβ oligomers.

Ion probe U-Pb dating of the Central Sakarya basement: A peri-gondwana terrane intruded by late lower carboniferous subduction collision related granitic rocks

Ion probe dating is used to determine the relative ages of amphibolite-facies meta-clastic sedimentary rocks and crosscutting granitoid rocks within an important ‘basement’ outcrop in northwestern Turkey. U-Pb ages of 89 detrital zircon grains separated from sillimanite-garnet micaschist from the Central Sakarya basement terrane range from 551 Ma (Ediacaran) to 2738 Ma (Neoarchean).
