The defective secretory activity of platelets in cirrhosis bleeders might be partly due to low polymerization of G-actin to F-actin which is required for platelet shape change and for the release of procoagulants. Cytosolic Ca2+ level seems to influence actin polymerization and thereby impairs platelet secretory respon... |
This paper presents a novel polynomial constraint for homographies compatible with the general planar motion model. In this setting, compatible homographies have five degrees of freedom-instead of the general case of eight degrees of freedom-and, as a consequence, a minimal solver requires 2.5 point correspondences. Th... |

OBJECTIVE |
Previous epidemiological studies have suggested that use of aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs) may be associated with reduced risk of breast cancer, but some studies have been limited in their ability to separate the effects of aspirin from other NSAIDs or to account for breast cancer risk f... |
METHODS |
We examined the incidence of breast cancer in association with self-reported aspirin, as well as other nonaspirin NSAID use in a large prospective cohort of postmenopausal women (n = 27,616). Over 6 years of follow-up, 938 incident breast cancers were identified. |
RESULTS |
After adjustment for other breast cancer risk factors, any current use of aspirin or other NSAIDs compared with no use was associated with a reduction in risk of breast cancer [relative risk (RR) = 0.80, 95% confidence interval (CI) 0.67-0.95]. There was a trend of decreasing risk of incident breast cancer with increas... |
CONCLUSION |
This prospective study corroborates other reports that use of aspirin might reduce risk of breast cancer.Effect of selenium deficiency on caprine polymorphonuclear leukocyte production of leukotriene B4 and its neutrophil chemotactic activity. |
These studies were designed to measure leukotriene B4 (LTB4) production by polymorphonuclear leukocytes (PMN) from selenium (Se)-deficient and Se-adequate goats. Leukotriene B4 was measured by both radioimmune and chemotactic activity assays in supernatants of PMN stimulated by calcium ionophore A23187. The concentrati... |
