The analysis of selective pressure acting in average over all sites of the entire data set and sub-datasets [see additional file 5: Table_suggestggesthatat purifying selection (with among-site variability) has been the main influence on the evolution of the entire Epd protein family (ω0 = 0.1553) and their sub-groups (ωMERPs = 0.115, ωFishBrain = 0.182, ωFishTj = 0.195, ωBasal = 0.051).
Photo-sharing sites, for example, are both a site of data aggregation and a venue for data collection and analysis.
Third, we conducted a principal components analysis of the amino acid frequency matrix at all sites of the 21 protein alignment data sets and obtained four major classes (or profiles) of amino acid frequency distribution at sites.
A stepwise decline in the annual rates of susceptibilities to penicillin from 1981 to 2000 at National Taiwan University Hospital (disk susceptibility data from all sites of isolates) and a high prevalence (60%–84%) of clinical PNSSP isolates were noted throughout the island (disk susceptibility data from all sites of isolates) (12).
Age, education, body mass index, smoking status, weekly frequency of exercise, sites of data collection, and history of hypertension, diabetes, and coronary heart disease were forced into the models to adjust for potential confounding effects.
Data for all sites of H3 N-terminal acetylation (H3K9, H3K14, H3K18, H3K23 and H3K27) and for the acetylation of lysine 5 and 16 on histone H4 at two typical positions of the upstream and core promoter, respectively, are shown in Figure 2. Additionally, detailed promoter acetylation profiles for each modification are available in the Additional File 1.
This committee covers the ethical approval of all three sites of our data collection.
A medical privacy breach led to the public posting on a commercial Web site of data for 20,000 emergency room patients at Stanford Hospital in Palo Alto, Calif., including names and diagnosis codes, the hospital has confirmed.
Home births attended by Registered Midwives were sampled independently from two strata based on site of data abstraction.
Second, fact-finding and the action it leads to should hold influence beyond the immediate site of data collection.
