So far, the frequency of horizontal gene transfer has been quantitatively established in model biofilms, using defined donor and recipient strains.
Overall, after injection of single, unselected melanoma cells, 27% initiated a tumor suggesting that so far the frequency of melanoma-initiating cells was significantly underestimated [ 12].
So far, the frequency of dead in bed syndrome has been suggested to be 5 6% of all deaths in diabetic patients <40 years old [ 79, 81].
This is in stark contrast to mutations found in the genomes of other tumors sequenced so far, where the frequency of recurrence is rarely above 20%to30%0%.
Nine out of 42 (22%) declared an increase, 19/42 (45%) a reduction, and 14/42 (33%) no change as far as the frequency of active periods is concerned.
As far as the frequency of hazards in the Upper Beas Basin is concerned it can be seen from Table 4 that the trend and frequency have been categorized under 6 headings for easy interpretation, namely: increasing rapidly, increasing slowly, constant, reducing rapidly reducing slowly and don't know.
As far as the frequency of mammography is concerned, the Association refers to the guidelines from the Royal College of Radiologists which suggest 1- to 2-year intervals for up to 10 years [ 23].
As far as the frequency analysis method is concerned, it does not matter whether the asynchronous event occurs during inspiration or expiration, or what type of asynchrony is encountered: trigger, flow or expiratory asynchrony.
For the EHGs recorded on women, our study proved that the best way to position the electrodes, as far as the frequency content of the EHG is concerned, is to align the electrode pairs with the median vertical axis of the uterus.
As far as the frequency of occurrence, both mononucleotides A/T and C/G had the most repeat with 112 and 103 times, respectively, followed by AGC/CTG (85 times), ACG/CGT (65 times), AAG/CTT (63 times), and CCG/CGG (47 times).
Results show geographical, diurnal, seasonal, and annual variations in the conditions required for DDP formation and confirm that arid regions have by far the highest frequency of occurrence with maxima in summer.
