Semiquantitative assessment of mRNA showed that in the majority of tumours, expression of TGF-beta s did not change markedly with treatment, i.e. beyond that which might have been caused by method reproducibility and tumour heterogeneity (variations of < 100% between pre- and post-treatment samples).
These differences in DNA methylation among different species may be caused by detection methods (primer numbers, amplification conditions, time of electrophoresis, and staining methods), material differences (seed, seedling, mature leaves), or genetic control.
This would be caused by different methods to assign an OTU to each sequence read.
Methylation, oxidation of methionines, tryptophans and cysteines, phosphorylations, amidations and deamidations may be caused by the method of preparation, separation, detection or identification.
This may be caused by the method used to determine the coefficients of Eq. (7).
Glucose response phenotype (i.e., monophasic or biphasic) was classified according to previous studies (13– 16), with a glucose threshold of 4.5 mg/dL as described by Tschritter et al. (13) to minimize fluctuations in glucose concentrations that may be caused by the method of glucose analysis rather than physiological reasons.
The discrepancy between the plasma and urinary clearance of 51Cr-EDTA represents a bias that can be caused by the different methods used to estimate the two clearances.
† Embryonic loss' cause: refers to whether it is important to distinguish natural embryo losses from those that may be caused by birth control methods.
The significant different seroprevalence observed may also be caused by the different methods, including antigen ELISA, IHA, conventional or multiplex PCR.
These decisions are not readily predicted from socio-demographic variables, but are rather associated with personal beliefs regarding the beginning of human life and the opinion that there is a moral difference between embryonic losses that occur spontaneously and those that may be caused by family planning methods.
