Frieke Kuper, C. (author), TNO Kwaliteit van Leven (author)Histologic examination of lymphoid organs has revealed immunotoxic effects of a broad range of substances. The thymus has proven especially sensitive. The relative lack of sensitivity of mucosa-associated lymphoid cells and tissues may be due to shortcomings in the way they are examined. Validation of ways to examine mucosal lymphoid tissues and...article 2006

Daanen, H.A.M. (author), TNO Defensie en Veiligheid (author)Several publications indicate that the infrared tympanic temperature (IRTT) underestimates the core temperature of the body when the ear canal is long, curvy and narrow. In order to quantify these observations, a study was performed in 10 subjects. The IRTT was determined and compared to the oesophageal temperature (Tes), taken as the reference...article 2006
