A hallmark of the disease is aggregation of the protein α-synuclein (αSyn), which is toxic to neurons. Harischandra et al. found that extracellular vesicles called exosomes isolated from serum collected from welders contained
Diamagnetism Wikipedia
Diamagnetism was first discovered when Anton Brugmans observed in 1778 that bismuth was repelled by magnetic fields. In 1845, Michael Faraday demonstrated that it was a property of matter and concluded that every material responded (in either a diamagnetic or paramagnetic way) to an applied magnetic field. On a suggestion by William Whewell, Faraday first referred to the phenomenon as
Diamagnetism an overview | ScienceDirect Topics
Vahak Marghussian, in Nano-Glass Ceramics, 2015. Diamagnetism. Diamagnetism is a very weak form of magnetism that is induced by a change in the orbital motion of electrons due to an applied magnetic field. This magnetism is nonpermanent and persists only in the presence of an external field. The magnitude of the induced magnetic moment is very small, and its direction is opposite to that of
Differences in magnetically induced motion of diamagnetic
For the types of fluids used for cell separation (aqueous solutions of Na +, Cl −, phosphates, amino acids, glucose, and proteins, such as 5% w/v bovine serum albumin) the solution is diamagnetic, and therefore, the magnetic susceptibility of the liquid phase is independent of the applied field. The susceptibility of the cell-label complex

If the particle is ferro- or paramagnetic (χ p >0) and the medium is diamagnetic (χ m <0), the difference between the two becomes positive, resulting in a positive value of F mag that signifies the attraction of the particle to the magnetic field. On the other hand, if the particle is diamagnetic (χ p <0) and the medium is paramagnetic (χ m >0) then the difference becomes negative, and

Ferromagnetism is a kind of magnetism that is associated with iron, cobalt, nickel, and some alloys or compounds containing one or more of these elements. It also occurs in gadolinium and a few other rare-earth elements. In contrast to other substances, ferromagnetic materials are magnetized easily, and in strong magnetic fields the magnetization approaches a definite limit called saturation.
