Our evaluation of oxime reactivation of AChE inhibited by a sarin analogue, O-methyl isopropylphosphonofluoridate, or a cyclosarin analogue, O-methyl cyclohexylphosphonofluoridate, indicated that AChE inhibited by these analogues was at least 70-fold more difficult to reactivate than AChE inhibited by sarin or cyclosarin.
The lower affinity of TCR pMHC-II inTCR pMHC-IIcombinteractionse lacombines4 'co-receptor help' to ensure that the average CD4+ T cell is almost 50-fold more difficult to stain with pMHC theramers than the average CD8+ T celack.
WA did increase two-fold in ATP consumption, most likely because α-amylase is 10-fold larger and likely more difficult to fold and has more disulfide bond pairing possibilities.
Avoid using small pieces of paper on your first try, as the folds will be more difficult to make and this may be frustrating.
However, when the expression level decreases as well as the fold change, it gets more difficult to separate true differentially expressed genes from false positives.
In vivo, protein folding is made even more difficult by the crowded environment of the cell, where proteins must assume their correct conformation while being constantly bombarded by high-energy collisions with neighboring proteins (Ellis and Minton, 2006).
A thick blood smear is used to quickly observe a larger volume of blood more quickly, which increases the sensitivity of the diagnosis by approximately 10-fold; however, it is more difficult to speciate the infection because of distortions in morphology.
This might be explained by higher contact-order (Plaxco et al., 1998) in beta-sheet proteins, which renders such proteins more difficult to fold (Bradley and Baker, 2006).
These differences will arise because α-amylase is a relatively larger (and likely more difficult to fold), has an odd number of cysteines (which may complicate disulfide isomerization) and has glycosylation, compared to insulin which is small, has even number of cysteines, and is not glycosylated.
We observed and measured that STM promoter activity increases with tissue folding, but it is very likely that STM induction indeed precedes tissue folding (although this would be more difficult to quantify, as this would involve measuring regional differential growth – see below).
This reflects the fact that models for the family level are much better as compared with the more distant models on the fold level which appear to be more difficult also for rescoring.
