BACKGROUND Using longitudinal panel data, the aim of this study was to examine the contribution of age, period, and cohort effects on changes in physical activity over time in a population-based sample of Canadians. We focused on three domains of physical activities: leisure time, commuting (i.e. walking and cycling), and daily activities (i.e. sedentary behavior). We also examined whether chan...

The atmospheric transport and deposition of aerosols has the potential to influence the chemistry and biology of oligotrophic alpine lakes. In recent decades, dust and nitrogen emissions to alpine ecosystems have increased across large areas of the western U.S., including Wyoming. Here, we use sediment geochemistry and Sr/Sr and Nd/Nd isotopes to examine historical dust deposition rates to alpi...

Two hundred consecutive new patients, with acute lymphocytic leukemia (ALL) have been studied with a battery of five cell marker assays to determine if a classification system with prognostic significance can be developed; 182 have been classified among four groups as follows: 33 T-cell, 3 B-cell, 126 common, and 20 undifferentiated ALLs. Patients with Tcell disease are likely to have unfavorab...

Remarks given in the review of Paper 1 should be taken into account, more particularly remarks about the expected limitations and real performances over the size range targetted by LOAC. Since we have presented in the revised version of paper 1 some new results confirming the performances of LOAC, we prefer not changing the text here. 2.
