Do tH2 lymphocytes from atopic patients treated with immunotherapy undergo rapid apoptosis after culture with specific allergens?
These results suggest that the shift from T(H)2 to T(H)1 induced by SIT in atopic patients may be mediated, at least in part, by the induction of an activation-induced cell death process in allergen-responder T(H)2 cells.
Certification did not reduce the risk of work injury among experienced tree-fallers in the province of British Columbia. Non-statistically significant increases in the observed risk of work injury in the months immediately following certification may be attributable to an intervention effect or a methodological limitation related to a lack of individual-level, time-at-risk exposure data.
