Fractional anisotropy of the white matter has shown that organization of the CS also reflects white matter injury and later motor impairments [ 40, 41].
The Kauffman Foundation, which researches such matters, has shown that the bulk of new jobs come from a tiny sliver of high-growth companies.Daniel Isenberg has spent 30 years immersed in the world of entrepreneurship as a (sometimes failed) entrepreneur and venture capitalist as well as an academic (he previously taught at Harvard Business School and is now at nearby Babson College).
Now in its 13th year, with nearly three-quarters of a million teens having completed the program, Money Matters has shown some remarkable results.
Whereas grey matter analyses have shown robust changes and a clear relationship with disease progression, 3 the extent of white matter changes and their relation to illness duration or the effects of medication remain in doubt.
Studies of ex vivo spinal dorsal column [13] and cerebral white matter [14] have shown that glutamate excitotoxicity could lead to death of oligodendrocytes and loss of axonal conduction.
Preliminary studies of deep brain stimulation targeting the subcallosal cortex (Brodmann area 25) and its adjacent white matter tracts have shown promise in treating depression, suggesting that disruption of the pathological limbic-cortical circuit may ameliorate treatment-resistant depression (Mayberg et al., 2005; Lozano et al., 2008).
To complicate matters, studies have shown resolution of PEx in patients chronically infected with P. aeruginosa treated with regimens devoid of anti-pseudomonal activity suggesting response is more complicated than a one-host and one-pathogen model [ 31, 32].
In addition to changes in white matter volume, studies have shown concurrent changes in white matter microstructure.
On this matter, previous studies have shown the role of membrane and/or amino acid biosynthesis, efflux transporters and CO2 fixation as multifunctional responses to chloride exposure in acidophilic species (Zammit et al. [2012]).
