All MSU specimen were centrifuged extensively to eradicate contamination with any urothelial or microbiological cell material.
Before experimental use, each preparation was extensively characterised for potential contamination by other cell types and for expression of tight junction-associated molecules as previously described [ 8].
Biological and organic-chemical contamination has been extensively considered by the COSPAR Panel on Planetary Protection (PPP) and has resulted in the internationally recognized regulations to which spacefaring nations adhere, and which have been in place for 40 years.
Some items, even if they were washed extensively with water, introduced Zn contamination.
In particular, sexual intercourse causing breast milk contamination was discussed extensively across respondent groups regardless of district of residence or distance to a health center and in both FGDs and IDIs (see Tables 3 and 4).
U.S. users and exporters sample grain elevators extensively, particularly when they suspect contamination, in order to ensure that levels don't exceed the domestic standard for aflatoxins of 20 ppb, while companies in developed countries that make cereal and other processed foods are "always sampling" for aflatoxin, Payne says.
Bacterial contamination has been studied extensively (Bischoff et al. 2009; Skinner and Leathers 2004) and several antimicrobial strategies, including usage of antibiotics, have been adopted in the first generation bioethanol production (Muthaiyan et al. 2011).
The contamination issue has been extensively examined and, to date, in the case of attractin for example, there is no evidence of contamination of purified preparations by CD26 [ 10, 11].
The radioactive contamination in the soil was extensively examined by MEXT, Japan.
The induction of two biomarkers extensively validated in the assessment of PAHs contamination ethoxyresorufin-O-deethylase activity (EROD) and Fluorescent Aromatic Compounds (FACs) was evaluated.
In the past decades, Cd contamination of soils has been extensively investigated (Chlopecka, 1996; Culbard et al., 1988; Pietz et al., 1978; Simmons et al., 2005).
