Geological and geotechnical models definition for 3rd level seismic microzonation studies in Central Italy

The 2016–2017 seismic events that struck central Italy led the Government to carry out a project to produce the third level Seismic Microzonation studies in 138 municipalities. These activities have involved m...

Complex magnetic order in nickelate slabs

Magnetic ordering phenomena have a profound influence on the macroscopic properties of correlated-electron materials, but their realistic prediction remains a formidable challenge. An archetypical example is t...

Conditional expression of Ki-Ras^G12V in the mammary epithelium of transgenic mice induces estrogen receptor alpha (ERα)-positive adenocarcinoma

Appropriate ‘in vivo’ models are crucial for studying breast cancer biology and evaluating the efficacy of therapeutic agents. Thus we engineered a novel transgenic mouse line expressing the human Ki-Ras bearing ...

Invasive species and their parasites: eastern cottontail rabbit Sylvilagus floridanus and Trichostrongylus affinis (Graybill, 1924) from Northwestern Italy

The eastern cottontail Sylvilagus floridanus is a native American lagomorph. Within the genus Sylvilagus, the eastern cottontail is the species with the widest distribution. From 1950s, the species was introduced...

Bergapten induces ER depletion in breast cancer cells through SMAD4-mediated ubiquitination

ERα function is crucial for the development of normal mammary gland as well as in the process of progression of breast cancer cells. Signals that target receptor levels contribute to regulate estrogens effects...

Estrogen receptor beta binds Sp1 and recruits a corepressor complex to the estrogen receptor alpha gene promoter

Human estrogen receptors alpha and beta are crucially involved in the regulation of mammary growth and development. Normal breast tissues display a relative higher expression of ER beta than ER alpha, which dr...

Farnesoid X receptor inhibits tamoxifen-resistant MCF-7 breast cancer cell growth through downregulation of HER2 expression

Tamoxifen (Tam) treatment is a first-line endocrine therapy for estrogen receptor-α-positive breast cancer patients. Unfortunately, resistance frequently occurs and is often related with overexpression of the ...

Physical Parameters of Evolved Stars in Clusters and in the Field from Line-depth Ratios

We present a high-resolution spectroscopic analysis of two samples of evolved stars selected in the field and in the intermediate-age open cluster IC 4651, for which detailed measurements of chemical compositi...

Hα Line and Photometric Variability in Magnetically Active Stars

The spatial association and evolution of photospheric and chromospheric active regions, on the Sun, traces the emersion of magnetic flux tubes. We show that atmospheric phenomena observed in solar-like stars c...

Rotational Modulation of Hα Emission in RS CVN Systems

The spectroscopic Hα observations of five RS CVn systems (UX Ari, HR 1099, Z Her, HK Lac, RT Lac) and of the contact system VW Cep here discussed were obtained in 1989, 1990, 1991, 1993 and 1994 with the 91-cm...

Flares on Active Binary Systems

Flares in the Sun and in binary stars seem to have the same physical nature but very different energetic power. The total energy released by flares on RS CVn binaries is in the range 10³⁵–10³⁸ erg while typical e...
