If a geologic boundary is known it is possible to modify the density estimate with data derived from field observations and mapping.
It is important to identify factors which modify mammographic density and thereby might be useful as a basis of preventive interventions.
The proposed process allows to easily modify the density and morphology of the foams, making them suitable for several engineering applications.
The absence of a crop on rows (unseeded vs. seeded rows) did not modify weed density and biomass before herbicide application in both corn and soybean.
The addition of carbachol, at the same dose, did not modify the density of blood vessels (δ = 1.80 ± 0.46).
Prospective studies of breast density (using standardised methods) and demographic (body size and drug history) data are required to elucidate factors (that is, age and lifestyle factors, and weight) that modify breast density, and whether these modify the relationship between density and risk.
Available data suggest that several hormonal and dietary factors can modify breast density; density increases with estrogen and progestin therapy and decreases following exposure to tamoxifen or ovarian suppression (Boyd et al., 1997, 2001; Greendale et al., 2003).
Our study observed an approximate 8% increase in the relative amount of mammographic density with high alcohol intake, which is within range of other breast cancer risk factors known to modify mammographic density (range 2-10%) [ 1, 2].
Nicotine exposure did not modify the density of glutamatergic inputs neither in WT or transgenic cultures, but reduced stubby spines (p = 0.033), without affecting filopodia and mushroom-like spines (Table 2) or the total spine density.
The treatment did not modify the density of CA3 pyramidal neurons neither in WT nor in Tg CHRNA5/A3/B4 mice, the major excitatory inputs in the CA1 region (Additional file 2: Figure S2b).
