Purification and characterization of a better-behaved Alzheimer’s disease protein
Alzheimer’s Disease (AD) is an incurable disease that causes memory, reasoning and thinking to deteriorate over time. AD is marked by brain atrophy and plaque-like deposits of a small peptide called amyloid beta (Aß) outside of brain
What can we achieve for average spin Hamiltonians in solid-state nuclear magnetic resonance spectroscopy?
Multiple-pulse sequences (MPS) have been widely applied in nuclear magnetic spectroscopy to manipulate spin Hamiltonians (such as isolating or enhancing certain interactions while removing the effects of all other interactions), to measure relaxation times, and to enhance
Diving into cell membranes with advanced solid-state NMR methods: harnessing the power of protons
Membrane proteins act as the gateways of the cell. They are essential for the signalling between cells and for the uptake of nutrients; they constitute major drug-targets in human, and their malfunctions are related to severe diseases
An organic gas instead of inorganic gases for the enhancement of 129Xe magnetic resonance signals through optical pumping
Several new methods have been developed in these two decades in nuclear magnetic resonance (NMR) spectroscopy, which make us accessible to weak signals hitherto unmanageable because of the low sensitivity. Among them, spin-exchange optical pumping (SEOP) can
NMR can now scrutinize the membrane of a living cell
Nuclear Magnetic Resonance (NMR) is a technique devised by physicists, that has developed into many applications. The most famous one is Magnetic Resonance Imaging that is commonly used in hospitals. In the research lab, NMR is generally
Relativity: Relatively uninteresting for chemists?
The periodic table of elements is among the corner stones of chemistry. In the given order, in both the periods (rows) and groups (columns), elements show some specific properties. However, when going around the bottom of the
Alternative determination of blood alcohol concentration
Alcohol consumption is a common and legal practice in most of the countries around the world which leads to numerous fatal traffic accidents, and other incidents like leisure injuries, alcohol poisoning and drug facilitated sexual assault. According
