“Background: Epidemiologic studies that examined whether lignans, the most important class of phytoestrogens in the Western diet, protect against breast cancer have yielded inconsistent results.
Objective: In this study, we conducted meta-analyses
on the association between lignans and breast cancer risk.
Design: We performed a systematic MEDLINE search to identify epidemiologic studies published between 1997 and August 2009. We calculated pooled risk estimates (REs) for total lignan exposure, dietary lignan intake, enterolignan exposure, and blood or urine concentrations of PFTα enterolactone and according to menopausal and estrogen receptor (ER) status of tumors.
Results: We included 21 studies (11 prospective cohort studies and 10 case-control studies) in the meta-analyses. Lignan exposure was not associated with an overall breast cancer risk (RE: 0.92; 95% CI: 0.81, 1.02; P for heterogeneity = 0.004). However, in postmenopausal women, high lignan intake was associated with a significant reduced risk of breast cancer (13 studies; RE: 0.86; 95% CI: 0.78, 0.94; P for heterogeneity = 0.32). Breast cancer risk was also inversely associated
with enterolignan exposure (4 studies; RE: 0.84; 95% CI: 0.71, 0.97) but not with blood or urine enterolactone concentrations. The associations were not significantly different between ER-status
subgroups (6 studies).
Conclusions: High lignan exposure may be associated with a reduced breast cancer risk in postmenopausal women. Additional work is warranted to clarify the association between lignan exposure and breast cancer risk. Am J Clin Nutr 2010; 92: Cediranib 141-53.”
“A bit patterning process using the ferromagnetic (FM)-antiferromagnetic (AF) transition in [001]-oriented L1(0) FePt1-xRhx films was investigated. First, the composition (x) dependence of magnetization (M-s) and magnetocrystalline anisotropy (K-u) of the films was studied. The films with 0 <= x <= 0.32 showed ferromagnetism (800 <= M-s <= 1100 emu/cm(3)) with a high magnetocrystalline anisotropy (1.7 x 10(7) <= K-u <= 7.0 x 10(7) erg/cm(3)), and the films with 0.34 <= x <= 0.40 showed antiferromagnetism. The composition of x = 0.34 was the threshold of the FM-AF transition. Next, the FM-AF transition was applied for bit patterning. Atomic diffusion was used for modifying the composition. Only the magnetic phase of the area whose composition crossed the threshold changed abruptly to the FM phase. FM dots with sizes (D) of 20 <= D <= 1000 nm were observed in the AF matrix by magnetic force microscopy. The dots with D > 100 nm formed multidomain structures, and the dots with D <= 100 nm formed a single-domain structure. (C) 2011 American Institute of Physics. [doi:10.1063/1.
