Lactate modulates CD4+ T-cell polarization and induces an immunosuppressive environment, which sustains prostate carcinoma progression via TLR8/miR21 axis
Leukocyte infiltration plays an active role in controlling tumor development. In the early stages of carcinogenesis, T cells counteract tumor growth. However, in advanced stages, cancer cells and infiltrating ...

Statistical Learning of Spatiotemporal Patterns from Longitudinal Manifold-Valued Networks
We introduce a mixed-effects model to learn spatiotemporal patterns on a network by considering longitudinal measures distributed on a fixed graph. The data come from repeated observations of subjects at diffe...

Variability of non-mutualistic filamentous fungi associated withAtta sexdens rubropilosa nests
A survey of the filamentous fungi other than the symbiotic one found in association withAtta sexdens rubropilosa colonies was carried out. Different fungal species (27 taxa) were isolated a few days after treatin...

Fiber Optics Reflectance Spectroscopy in the Entire VIS-IR Range: a Powerful Tool for the Non-invasive Characterization of Paintings
Fiber optics reflectance spectroscopy (FORS) in the entire 380–11,000 nm range has been used to non-invasively characterize Leonardo’s painting Madonna of the Yarnwinder. A preliminary analysis of the recorded sp...

Occurrence of killer yeasts in leaf-cutting ant nests
Killer activity was screened in 99 yeast strains isolated from the nests of the leaf-cutting antAtta sexdens against 6 standard sensitive strains, as well as against each other. Among this yeast community killer ...

Optical Fibers for the Cultural Heritage I: Picture Varnishes as Thermosensitive Fiber Cladding
Varnishes used for the protection of paintings are also key factors influencing the appearance of paintings, since they are able to provide more gloss and saturated colors. In order to give a stable appearance...

Detection of Alteration Products in Artworks by Non-Destructive Spectroscopic Analysis
The use of fiber optics reflectance spectroscopy (FORS) in the near IR is proposed as a simple, fast, and totally non destructive method to detect alteration products. Indeed gypsum and calcium oxalates show v...

Role of vibronic coupling and of conformational substate distribution in determining the features of copper-protein EPR spectra
It is stressed that the presence of a metal ion directly bound to a protein can introduce elements of complexity, such as vibronic coupling, which cannot be ruled outa priori. As a typical example, two copper pro...

Decay from photo-excited doubly degenerate electronic levels. A simple interpretative approach
A simple physical model for interpreting decay processes from excited doubly degenerate electronic levels is described. It considers different de-excitation channels on the potential energy surfaces in the two...

A seeming exception to the Jahn-Teller effect
Some statements related to the Jahn-Teller effect are often misunderstood. Here it is stressed that there exist physical systems for which electronic degeneracy cannot be resolved by vibrational modes.

A new fluorescence from carboxylic and amino acids
A new fluorescence band at (400÷430) nm for many carboxylic and amino acids is reported. An excitation band with a maximum around 330 nm is always observed, while further bands can be present at lower wave-len...

The role of vibronic coupling in the interpretation of spectroscopic and structural properties of biomolecules
The aim of the present article is to review several biomolecules, the spectroscopic and structural properties of which have been so far interpreted in the light of the Jahn-Teller effect. Indeed the importance...

Spectroscopic and structural properties of metallo-proteins
The author is aware that the argument treated in this review article is so wide that it cannot be exhausted in a single paper and, perhaps, not even in a book. However, the principal purpose was to give a pano...
