An investigation by the Environmental Working Group found BPA on 40percentt of receipts sampled from major U.S. businesses like McDonald's, CVS, KFC, Whole Foods, WalMart, Safeway -- even the post office.
Information collected on mobile devices through Dashboard include the participant, household, breastfeeding and study satisfaction surveys, height and weight, sample data, field visits, consent data, vaccination information, study gift receipt, supervisor sample reception, and sample temperature data.
Upon receipt of samples at the study site, they were added to a central sample database, aliquoted and stored at −80°C until analysis.
On receipt, 30 samples were randomly selected, washed with distilled water, weighed, and double bagged in separate polyethylene bags, sealed and labelled accordingly and kept frozen.
Upon receipt, the samples were divided into two aliquots.
On receipt, ascites samples were processed aseptically as described previously (Ingram et al, 2010).
After logging receipt, the samples were forwarded to the Medical Oncology Department at Charing Cross Hospital for assay.
Upon receipt, stool samples were stored at −20°C and analysed for tumour M2 PK within 1 month.
