Quantitation, Distribution and Secretion of Plasma Phospholipid Transfer Protein
Secretion of PLTP by mouse 3T3-L1 preadipocytes was also investigated. Characteristics of mouse adipocyte-secreted PLTP were similar to those of human plasma PLTP. Secretion of mouse PC transfer activity increased after differentiation.

Direct Quantitation of Heat Loss in Human Subjects Using Infrared Thermography
Infrared thermography (IRT) can be used to quantitate changes in mean surface temperature. This value is one variable used in heat loss equations which permits computation of radiant, convective, evaporative and total heat losses from subjects. The portable, non-contact, non-invasive nature of the …
