Differential absorption of exogenous and endogenous cholesterol in man

Journal of Lipid Research, 1983
Cholesterol absorption was measured in six patients by a triple-lumen intubation technique: 1) to determine whether isotopic exchange between radiolabeled lumenal cholesterol and unlabeled mucosal cholesterol occurs during cholesterol absorption ...

Influence of Absorption Cross-Sections on Retrieving the Ozone Vertical Distribution at the Siberian Lidar Station

Atmosphere, 2022
The purpose of this paper is to study how the application of different sets of absorption cross-sections influence the ozone vertical distribution (OVD) in the upper layers of the troposphere—stratosphere in the altitude range ~(5–45) km, using a ...
