Except for the deposits of PrPSc as the initiative agent, alterations of these bioactive proteins are either intermediate or consequent events in TSE pathogenicity and proposed the potential linkage of these bioactive proteins with the pathogenesis of prion diseases.
Among the most important mechanisms are decreased ability of antibacterials to penetrate the bacterial cell wall, active efflux of antibacterial agents, inactivation of antibacterial agents, destruction of antibacterial agents, alteration of antibacterial target sites, development of bypass pathways around antibacterial targets, and constitutive phenotypic variation in bacterial physiology.
Different types of response modification can be distinguished: changes in the receptors for growth and differentiation factors and their cytoplasmic and nuclear signal transduction pathways; increased resistance of initiated cells to cytotoxic agents; alterations in junctional cell-to-cell communications.
Moreover, the success of targeted anticancer therapy largely depends on biomarkers that can identify patient subgroups that may respond to specific therapeutic agents because alterations in a particular cancer driver usually exist in only a small subset of patients.
It speeds up exsolution within homogeneous solid phases and devitrification of any glass that may be present, and it is a potent agent in the alteration, leaching, and replacement of minerals.
Additional factors that compound this neuroinflammatory process include the release of excitatory amino acids, hyperglycemia, exposure to neurotoxic pharmacologic agents, hemodynamic alterations, coagulopathy, and hypoxemia [ 3].
The final common pathway in the mechanisms of action of ionizing radiation and many chemotherapeutic agents include alterations of DNA and the production of reactive oxygen species (ROS) [ 1, 2].
Low-salinity waterflooding (LSWF) is used as a wettability alteration agent in carbonate reservoirs and improves displacement efficiency.
Aggregated A β appears to be a robust agent driving this alteration, since markers of activated microglia were densely colocalized within the deposits [ 137, 138].
In addition, it is not always possible to determine with precision the causal agent of any given alteration (Alberto et al. 2005).
