context: Aspirin therapy reduces the risk of cardiovascular disease in adults who are at increased risk. However, it is unclear if women derive the same benefit as men. Objective: To determine if the benefits and risks of aspirin treatment in the primary prevention of cardiovascular disease vary by sex. Data Sources and Study Selection: MEDLINE and the cochrane central Register of controlled Trials databases(1966 to March 2005), bibliographies of retrieved trials, and reports presented at major scientific meetings. Eligible studies were prospective, randomized controlled trials of aspirin therapy in participants without cardiovascular disease that reported data on myocardial infarction(MI), stroke, and cardiovascular mortality. Six trials with a total of 95 456 individuals were identified; 3 trials included only men, 1 included only women, and 2 included both sexes. Data Extraction: Studies were reviewed to determine the number of patients randomized, mean duration of follow- up, and end points(a composite of cardiovascular events [nonfatal MI, nonfatal stroke, and cardiovascular mortality], each of these individual components separately, and major bleeding). Data Synthesis: Among 51 342 women, there were 1285 major cardiovascular events: 625 strokes, 469 MIs, and 364 cardiovascular deaths. Aspirin therapy was associated with a significant 12% reduction in cardiovascular events(odds ratio [OR], 0.88; 95% confidence interval [cI], 0.79- 0.99; P=.03) and a 17% reduction in stroke(OR, 0.83; 95% cI, 0.70- 0.97; P=.02), which was a reflection of reduced rates of ischemic stroke(OR, 0.76; 95% cI, 0.63- 0.93; P=.008). There was no significant effect on MI or cardiovascular mortality. Among 44 114 men, there were 2047 major cardiovascular events: 597 strokes, 1023 MIs, and 776 cardiovascular deaths. Aspirin therapy was associated with a significant 14% reduction in cardiovascular events(OR, 0.86; 95% cI, 0.78- 0.94; P=.01) and a 32% reduction in MI(OR, 0.68; 95% cI, 0.54- 0

The recently domesticated species, cephalaria joppensis (cJ), is emerging as a new alternative forage crop in Israel. It has high biomass potential and nutritional values that are comparable to forage wheat. However, cJ emerges slowly under cold conditions, which hinders its development as a major winter crop. Additional tolerance for abiotic stress would improve its performance as a forage crop. We examined the effects of several abiotic factors (i.e., cold, salinity, drought and pH) on cJ germination under controlled conditions. The effect of temperature was studied by incubating seeds at different temperatures between 7°c and 35°c. The effects of salinity, osmotic potential and pH were tested by incubating seeds at different Nacl, PEG and pH levels, respectively. Temperature, salinity and osmotic potential significantly affected germination;whereas pH did not. Temperature did not affect the final proportion of germinated seeds, but did affect other germination-rate variables, indicating that germination rate might be the limiting factor under field conditions. Salinity also affected germination-rate variables, but not the proportion of seeds that germinated. Notably, cJ was found to be relatively resistant to high salt concentrations, with a 273 mM Nacl threshold for germination, indicating its potential as a relatively salt-tolerant forage crop. Both the proportion of germinated seeds and the germination rate were highly sensitive to the osmotic-potential treatments, indicating that drought resistance will remain the biggest challenge for cJ. This study provides baseline data for a rapid and efficient system for further screening for abiotic-stress tolerance among wild and cultivated lines of cJ.
