Occurrences of unknown origin were excluded from analysis, but when reasonable guesses could be made as to point or general area of origin (e.g., 1995 outbreak of hemorrhagic fever due to Ebola Ivory Coast as originating at Plibo, Liberia), they were included.
Also, the rate of the changes in the rules are not known which means we are faced with the lack of information about rate of occurrence of new unknown conditions as a result of dynamics environments.
If no such peptide could be identified, the longest peptide generated by in silico cleavage of the sequence at each occurrence of an unknown amino acid and/or stop codon was used.
Over 80% of chronic low back pain (CLBP) occurrences are of unknown origin [ 1].
However, protein sequences in PARCEL tracts differ in several ways, including their tandem repetition, conserved amphipathic secondary structure, association with membrane proteins and occurrence in genes of unknown function.
Kovacs et al. (2010) produced an identical value for olivine bearing [Ti] and [triv] defects, although their absorption coefficients for [Si] and [Mg] defects were compromised by the occurrence of a previously unknown defect involving boron which comprised a significant proportion of the water in the "Pakistani" olivine used in their experiments (Ingrin et al. 2014).
A further advantage of RNA22 is its sequence based pattern approach: the occurrence of further yet unknown motifs should not influence the RNA22 prediction quality of independent miRNA target site as long as no biological relationship is given.
Moreover, the types of modifications and the occurrence of digestion are unknown in most cases.
Whether perioperative hemodynamic fluid management aiming to provide an adequate tissue perfusion could influence the occurrence of POPF is unknown.
Although the exact mechanism behind the occurrence of MTB remains unknown, it is likely that MTB is associated with changes in the gastric mucosa usually associated with atrophy and/or IM, such as the widening and shortening of the intervening part between foveolae.
