It is defined as any undesirable modification of air by substances either toxic or likely to have adverse effects on health.
Errors happen on proteins including abnormally synthesized proteins, protein unfolding, abnormal cleavage, undesirable posttranslational modifications, can cause protein self-assembling into toxic oligomeric structures or aggregation into cytosolic inclusions.
Besides this, the reason for low protein production with decreased enzyme activities at higher UV treatment periods may be due to the longer exposures of the microbe to harsh UV radiation which resulted in undesirable genetic modifications inside the cells [26].
In contrast, phenolic compounds might reduce the quality of sunflower proteins by inhibiting digestibility, causing undesirable browning and structural modifications, and altering protein functional properties and behavior in various food matrixes.
In terms of the production of human therapeutic glycoproteins in plant systems, it is necessary to inhibit undesirable plant-specific posttranslational modifications in plants and to glycosylate target proteins in a manner similar to human systems via genetic engineering [reviewed in [ 34, 35]].
Most failures are categorized as case (3) discussed above: update rule modifications that correct undesirable transitions cannot also preserve desirable node state transitions within a limit cycle (accounting for 96%, 71%, and 58% of the failures, for k = 1, 2, and 3, respectively).
To remove the undesirable CYP3A4 TDI activity, structural modification was focused on the 2,4-difluoroaniline moiety on the basis of the assumption that this moiety would be involved in mechanism-based inhibition of CYP3A4 via oxidative metabolism.
Furthermore, to raise the undesirable long-term degradation of PCL, modifications in the form of blend or copolymers are done with other hydrophilic polymers (Burke et al. 2004).
This is in part due to the physical properties of the resins on which the synthesis is conducted, but it is also a consequence of imperfect coupling and undesirable side-reactions that create mutagenic modifications to the nucleobases.
The results of electrochemical impedance spectroscopy (EIS) and Fourier transform infrared (FTIR) for pristine and 1 wt.% MgF2-coated LiCoO2 further demonstrates that modification layer suppresses the undesirable growth of solid electrolyte interface (SEI) film, which greatly contributes to the improved electrochemical performances after surface modification.
