In regards to metabolic dysfunction and aging, it has been suggested that the connection between energy regulation and increasing age may also be controlled by alterations in BDNF levels [41].
McCarty et al. reported that natural pathologic calcifications contain several crystalline phases and that HA nucleation may be controlled by hydrolytic alteration of precursor calcium phosphate phases such as octacalcium or tricalcium phosphates.
The frequency of state alterations can be controlled by the degree of the stochastic fluctuations (small variance – no/few state changes, large variance - frequent state changes), wherefore it can be regarded as an explicit control parameter.
- Decreased PTEN expression, through loss of heterozygosity, chromosomal rearrangement and/or epigenetic silencing, is observed in over 50% of all BBC cases and in 80% of familial BBCs., - A recent paper suggests that PI3K/AKT pathway alteration, which can be controlled by either EGFR and/or PTEN, is the highest in BBC among all BC subtypes.
This effect involves an alteration of expression of genes regulating mitochondrial dynamics (shown by us to be controlled by PGC1α).
The onset of low-temperature alteration identified at the base of the aquifer is thought to control aquifer thickness, and may itself be controlled by thermal flux from below (Morse and McCurry 2002).
Nevertheless, it is well established that switching between direct development and diapause is controlled by the alteration of hormonal signalling.
We have recently developed a library of poly(β-amino ester)s (PBAEs) that form networks with a wide range of mechanical properties and degradation rates that are controlled by simple alterations in the macromer molecular weight or chemical structure.
The extent of wettability alteration is controlled by CO2 exposure time; as such time is increased, alteration of wettability progresses towards an apparent limit.
These trends in fluid composition and mineral alteration are controlled by various coupled mechanisms.
