wnloaded role of the estrogen receptor β (ERβ) in the colon has received considerable interest, yet in vivo ls are needed to better define its protective actions. In the present study, wild-type (WT), ERα, Rβ knockout (αERKO and βERKO) mice were injected with azoxymethane, a colon chemical carn. Fourteen weeks after azoxymethane exposure, the incidence of aberrant crypt foci (ACF) was ed by met...

the creep/recovery behavior of wood flour-polypropylene was compared with medium density fiberboard (mdf) and particleboard. for this purpose, wood flour-polypropylene composites (with and without compatibilizer)were manufactured by using a laboratory twin-screw extruder. the mdf and particleboard panels were obtained from local producers. short term flexural creep tests at 30% of ultimate bend...

Aberrant crypt foci (ACF) originally described in rodents treated with colon-specific carcinogens have been identified also in humans at high risk of colon cancer (CRC) and are extensively used as cancer biomarkers. However, studies documenting the heterogeneity of ACF have questioned their precancerous nature. Recently, we described dysplastic foci depleted of mucins (MDF) in the colon of rats...

In human visual analysis, the initial processing of motion and chromatic signals may be mediated by feed-forward pathways from striate cortex to segregated areas of extrastriate cortex. The time-course of occipital to temporo-parieto-occipital motion processing was unknown, as was the selectivity of the effect of transcranial magnetic stimulation (TMS) on motion processing. TMS delivered over o...

In this paper, we propose a new general framework for learning and recognizing spatiotemporal events (or patterns) from intensity image sequences. This scheme is general in that it does not impose any motion model on the input. A multiclass, multivariate discriminant analysis technique has been used to automatically select the most discriminating features (MDF) which is shown to be better suite...
