To evaluate the changes in urinary phthalate concentrations in specimens collected from the same infant, we computed Spearman correlations between replicate urine specimens.
Numbers of particles found in specimens collected from hands of 50 shooters varied from zero to numbers greater than 100 and were strongly correlated with the time interval between last shooting and collecting specimens.
Clade C consists exclusively of specimens collected from the north.
A Chinese study published in 2001 used the molecular biological technique restriction fragment length polymorphism to analyze the differences in DNA sequence between 23 A. gallica specimens collected from the Northern Hemisphere.
NSCLC specimens collected from 205 patients between November 2009 and January 2011 were selected to detect EGFR gene mutations with real-time polymerase chain reaction (RT-PCR) and to detect EGFR gene copy number with fluorescence in situ hybridization (FISH).
In Uruguay, the first evidence of the circulation of these viruses came from a study of serum specimens collected from blood donors between 1985 and 1987 that showed a seroprevalence of 1%, as measured by indirect fluorescent antibody (IFA) test using Hantaan and Seoul antigens (11 ).
In both seasons, the body length of the specimens collected from site A was greater than that of specimens from site B, and there was a significant difference in body length between the two sites in March (P < 0.01).
A study of banked specimens collected from premenopausal women in the 1980s reported an SCC of 0.5 between samples collected 2 weeks apart, but 0.3 for samples collected 4 weeks apart (Nepomnaschy et al. 2009).
A study assessing for discordance between HIV pVL measured via RT-PCR, with specimens collected in ETDA-containing tubes versus PPTs, under varying processing protocols, demonstrated that transferring plasma from PPTs to a separate collection tube prior to specimen freezing eliminated the discordant, higher levels seen with specimens collected in PPTs vs. EDTA tubes [14].
For specimens collected between November 2004 to June 2007, RNA was extracted from 100 µl of each respiratory specimen using an inhouse GuSCN based extraction protocol [11] or Qiagen Viral RNA mini kits, according to the instructions of the manufacturer (Qiagen, Hilden, Germany).
In Gabon, the prevalence was 5.8% in isolates obtained from a variety of specimens collected between 2009 and 2012 [ 20].
