Chromosomal gain comprising this region has been found as a frequent event in uterine cervix cancer [15] and HNSCC [16] and amplification of the entire chromosome arm 1q is considered an early event in breast carcinogenesis [17].
Persistent pain following labour is an important socioeconomic factor and has been found to be as frequent as 1 in 10 women [ 43].
The melanoma stem cell, initially shown to be rare with a frequency of 1 in 10 cells using a NOD/scid xenograft model, was found to be as frequent as 1 in 4 with the use of the NSG mouse and an experimentally enhanced host microenvironment (Quintana et al, 2008).
S. aureus (18%), Klebsiella (18%) and C. albicans (18%) were found as the most frequent microorganism causing CRS.
In our previous study, the CYP2C19 deletion allele was found twice as frequent in familial breast cancer cases (5.8%) as in controls (2.3%), whereas CDH19 was observed once in both familial (1.0%) and control cohorts (0.8%) [ 4], implicating the need for a larger dataset for the evaluation of their disease relatedness.
Anxiety disorders have been found to be twice as frequent as affective disorders, and 4 8 times more frequent than major depressive disorders, in older samples (Beck and Stanley 1997).
While traditionally MRSA was a typical example of a nosocomial pathogen, it is now frequent found as causative agent of community-associated infections among patients without known risk factors for hospital-acquired (HA -MRSA [1], [2], [3], [4], [5], [6], [7].
When we examined isolated hypoxemia (PaO2 < 60 mmHg), we found that it was nearly as frequent as hyperoxia.
Among these compounds the most frequent copper phosphate found as a corrosion product is libethenite (Cu2(often4) often associated with cremation sites.
Using singleton indels, we find that insertions are over twice as frequent as deletions, at least for this data set, which consists of universal conservative proteins, largely represented by Metazoa, Viridiplantae and Fungi.
