It had generally been difficult to utilize a magnetic field for controlling the texture of diamagnetic ceramics because of their extremely small susceptibility; however, the possibility of controlling the texture by a magnetic field occurred with the development of superconducting magnets.
In contrast, the small susceptibility changes following exposure to BufferGel, SPS, and the HEC placebo were not significant.
They suggested that the observed contrast within white matter may be explained partly by a small susceptibility difference between myelinated fibres and surrounding tissue.
Because the susceptibility-induced gradients increase with increasing field strength, a small susceptibility difference between myelinated fibres and surrounding tissue would perfectly explain the fact that we obtained a similar contrast as Hajnal, at a much shorter echo time.
However, their high production cost, low operational stabilities, availability in small amounts, susceptibility to attack by proteases and activity inhibition limit their commercial applications in industrial and environmental biotechnology [9].
One finds a small positive susceptibility independent of temperature comparable with the diamagnetic contribution, so that the overall susceptibility of a metal may be positive or negative.
The extremely low elevated temperature and the small specific absorption rate (SAR) relevant to the gentle slope from the time vs. temperature rising curve were found to be primarily due to a stronger anisotropy (or a smaller magnetic susceptibility) of CoFe2O4 hard spinel ferrite nanoparticles compared to the soft spinel ferrite nanoparticles.
Stomatoyannopoulos emphasized that the GWAS 'story' in common diseases is more concerned with identifying such pathways than with individual, small effect susceptibility genes.
Models of the genetic architecture of complex traits (33) predict that large numbers of small effect susceptibility loci remain to be discovered, some of which should be tractable to well-powered GWAS.
The most recent large scale DNA analyses implicated, apart from the APOE locus, 19 loci containing common, small-effect, susceptibility variants in over 100 AD candidate disease genes, such as CR1, CLU, PICALM, BIN1, EPHA1, MS4A, CD33, CD2AP and ABCA7 [ 5– 8].
