Age-corrected mortalities from cancer at 17 major body sites were correlated with the apparent dietary selenium intakes estimated from food-consumption data in 27 countries. Significant inverse correlations were observed for cancers of large intestine, rectum, prostate, breast, ovary, lung and with leukemia; weak inverse associations were found for cancers(More)
The per-capita intakes of zinc, cadmium, copper and of chromium were estimated from food consumption data in 28 countries and were found to correlate directly with the age-corrected mortalities from cancers of intestine, prostate, breast, leukemia, skin and of other organs, suggesting that the anticarcinogenic effect of selenium is counteracted by other(More)
Grain legumes play a worldwide role as a source of plant proteins for feed and food. In the model legume Medicago truncatula, the organisation of protein storage vacuoles (PSV) in maturing seeds remains unknown. The sub-cellular events accompanying the accumulation of vicilin (globulin7S) were analysed during seed mid-maturation. Immuno-detection of vicilin(More)
PURPOSE Oral mucositis (OM) is a debilitating toxicity of chemoradiotherapy for head and neck cancer (HNC). This randomized, placebo-controlled, double-blind study evaluated the efficacy and safety of palifermin to reduce OM associated with definitive chemoradiotherapy for locally advanced HNC. PATIENTS AND METHODS Patients receiving conventionally(More)
The seed coat is involved in the determination of seed quality traits such as seed size, seed composition, seed permeability, and hormonal regulation. Understanding seed coat structure is therefore a prerequisite to deciphering the genetic mechanisms that govern seed coat functions. By combining histological and transcriptomic data analyses, cellular and(More)
BACKGROUND Detailed information about how patients with head and neck carcinoma (HNC) are treated across practice settings does not exist. The authors conducted a prospective, observational study to examine the patterns of care for a series of patients with newly diagnosed HNC in the United States and to test 2 hypotheses: 1) There is no difference in the(More)
PURPOSE To determine the optimal dose of combination topotecan, cisplatin, and gemcitabine in advanced non-small cell lung cancer patients. MATERIALS AND METHODS This single-center, single-practice, phase I trial enrolled chemotherapy-naïve patients with inoperable stage IIIB/IV disease. Initial treatment was topotecan (0.5-2.0 mg/m(2)), cisplatin (20(More)
The grapevine downy mildew (Plasmopara viticola) provokes severe damages and destroys the harvest in the absence of an effective protection. Numerous fungicide treatments are thus generally necessary. To promote a sustainable production, alternative strategies of protection including new antifungal molecules, resistant genotypes or elicitor-induced(More)
Inbred female C3H/St mice exhibit the normal incidence of spontaneous mammary adenocarcinoma of 80--100% if they are maintained on a standard commercial laboratory diet containing 0.15 ppm of selenium with meat and dried skimmed milk as major sources of protein. The tumor incidence drops to 42% if animals of the same strain are kept on a diet containing(More)
The joint administration of 2 ppm of arsenic as arsenite and of 2 ppm of selenium as selenite in the drinking water of inbred female C3H/St mice increases the incidence of spontaneous mammary adenocarcinoma significantly over the simultaneous controls and animals receiving 2 ppm As as arsenite or 2 ppm Se as selenite alone, indicating that arsenic abolishes(More)
