beta-Carotene has no influence on the measured haemostatic indicators, and cardiovascular protection for beta-carotene via a beneficial effect on haemostasis seems improbable. 展开 关键词: Keywords Haemostasis smoking thrombosis fibrinolysis DOI: 10.1097/00001721-199502000-00009 ...
The concentration of beta-carotene was measured in the stored serum samples from 271 men who were subsequently notified as having cancer and from 533 unaffected controls, matched for age, smoking history and duration of storage of the serum samples. The mean beta-carotene level of the cancer ...

The epidemiologic studies should be carefully interpreted because dietary habits may be misclassified and smoking may reduce plasma beta-carotene concentrations. Observational epidemiology cannot definitively resolve whether associations are indeed due to beta-carotene, or to other components of fruit and ...
