Underlying and contributing causes of death information were obtained from NDI. Due to limited numbers of historical samples for drinking water contamination, ATSDR conducted a historical reconstruction of the contamination using ground water fate and transport and distribution system models.
We aimed to determine whether antimicrobial surfaces prevent HCAI, transmission of antibiotic-resistant organisms (AROs), or microbial contamination, we conducted a systematic review of the use of antimicrobial surfaces in patient rooms.
We first used Trimmomatic to remove the potential Illumina adapter contamination and conducted reads clipping and trimming.
To exclude the possibility of genomic contamination, we conducted a "no-RT control" in every single PCR using non-reverse transcribed mRNA instead of cDNA.
To address the possibility of contamination, we conducted a mixing experiment where we combined high quality RNA-Seq samples (identified as having a DR < 0.1) in controlled ratios.
Quality control of the honey pill (i.e., assessment of weight variation, disintegration, moisture content, and microbial contamination) was conducted following WHO guidelines on good manufacturing practices (GMP) for herbal medicines [ 19].
Sex differences in WASH provision are of interest in the WASH sector and were found to be present in a previous school-based hand contamination study conducted in this region.
To ensure true genotypes could be distinguished from variant clones produced by somatic mutation, PCR mutagenesis, and/or interculture and intraculture environmental contamination, we conducted the following quality control experiments.
House dust samples have been collected in most of the reviewed studies and have served as a reliable indicator of residential pesticide contamination (studies conducted at the PNASH Center), although not necessarily as a surrogate for children's exposures (Curl et al. 2002; Fenske et al. 2002b; Lu et al. 2000; Simcox et al. 1995).
To prevent cross-contamination, we conducted all PCRs with a negative control and in the absence of positive controls.
