A control probe revealing a band of <2.8 kb allows a check on the homogeneity of migration throughout the gel and is useful in cases of a small premutation and/or a premutation with skewed inactivation, and for the detection of migration artefacts (caused for example by inappropriate DNA extraction protocol, samples extracted from blood collected in Lithium Heparin tubes, or sample overloading).
Furthermore, sometimes inappropriate choice of feature extraction methods and classification methods in the CAD systems can make meaningless results to understand disease.
If the required data (i.e., means and standard deviations of pre- and post-intervention values) were not reported in the article or presented in an inappropriate format for data extraction (e.g., graph instead of values), the corresponding authors were contacted and asked to provide the missing values.
After discarding inappropriate areas for RNA extraction, the tissue was mechanically macerated with liquid nitrogen and transferred to 1.5-ml microtubes, which were RNase and DNase free and contained 1,000 μl TRIzol (Invitrogen, Carlsbad, Calif., USA).
Globally, cataract extraction was considered inappropriate in patients without impaired visual function with a visual acuity higher than 0.1, or if in the presence of glare or difficulty with recreational activities the visual acuity was higher than 0.4, depending on surgical complexity.
So, it is inappropriate to be used for feature extraction of large-scale texts [27, 28].
Inappropriate methods or control parameters of gas extraction in combustion-prone longwall mining gobs may trigger a series of secondary accidents, such as the formation of excessive carbon monoxide, and even a gas explosion.
Cardiac stimulation by adrenergic cascade may be useful in hypoxia to optimize oxygen extraction from water, but probably inappropriate in the complete absence of oxygen.
Since the objective was to obtain an instrument as similar to the original as possible, extraction of additional contents was considered inappropriate.
Mass spectrometry on extracts of connective tissues is difficult; it is possible, that the extraction buffer used (0.1 M Tris buffer pH 7.5) was inappropriate.
