Estrogen (ER) and progesterone (PgR) receptors were evaluated in the tumor tissue (T) and in the mammary gland far from malignancy (D) in 36 breast cancers. Results were correlated with the pathological grading of the tumor and the axillary nodal status. It is suggested that a lower cancer malignancy with negative nodes and lower values of pathological grading (G1-G2) may be associated with a high level of ER in the mammary parenchyma far from the tumor (D).

The Permian succession of the Tione Basin (Val Rendena, Trento) includes the Collio Formation, a volcanic pile of rhyodacitic composition and the overlying Arenarie di Val Gardena Formation. Major and trace elements geochemistry of the volcanic rocks shows a calc-alkaline affinity and significant analogies with the coeval lavas and ignimbrites of the Monte Luco volcanic succession. Artinskian to Kungurian palynostratigraphic age of the Collio Formation from the Val Rendena matches the Kungurian to Ufmmian age (260-255 Ma) of the Tregiovo Formation from the Monte Luco sequence and the radiometric age of the Permian volcanites of Lugano. The Collio Formation appears to be younger than the Atesina Permian Volcanic Sequence. -Authors
