Serum Vitamin D as a Biomarker in Autoimmune, Psychiatric and Neurodegenerative Diseases.

2022

Vitamin D is a steroid hormone regulating calcium-phosphorus homeostasis, immune response and brain function. In the past thirty years, an increasing number of cohort studies, meta-analyses and randomized controlled trials (RTCs) evaluated the serum levels of 25-hydroxyvitamin D [25(OH)D], which is considered the Vitamin D status biomarker, in patients affected by neurological, psychiatric and autoimmune diseases. Although an association between low 25(OH)D serum levels and the prevalence of these diseases has been found, it is still unclear whether the serum 25(OH)D measurement can be clinically useful as a biomarker for diagnosis, prognosis and predicting treatment response in neurodegene…

The ALHAMBRA survey: evolution of galaxy clustering since z∼1

2014

We study the clustering of galaxies as function of luminosity and redshift in the range $0.35 < z < 1.25$ using data from the Advanced Large Homogeneous Area Medium Band Redshift Astronomical (ALHAMBRA) survey. The ALHAMBRA data used in this work cover $2.38 \mathrm{deg}^2$ in 7 independent fields, after applying a detailed angular selection mask, with accurate photometric redshifts, $��_z \lesssim 0.014 (1+z)$, down to $I_{\rm AB} < 24$. Given the depth of the survey, we select samples in $B$-band luminosity down to $L^{\rm th} \simeq 0.16 L^{*}$ at $z = 0.9$. We measure the real-space clustering using the projected correlation function, accounting for photometric redshifts uncert…

ELI Principles for the Covid 19 Crisis”: argini e contrappesi contro l’abuso dello stato di eccezione entro lo spazio giuridico europeo

2020

Le misure eccezionali -e prima ancora la dichiarazione dello stato di emergenza/eccezione- in risposta alla emergenza da Covid-19 - varate da quasi tutti i Paesi UE si accompagnano a minacce palesi o velate contro la tenuta dei principi democratici e dello stato di diritto . L'European Law Institute, organizzazione non governativa con sede a Vienna, ha dunque varato un decalogo di Principles rivolti a Stati e altre Istituzioni politiche, incentrato sui limiti cui la legislazione nazionale, pur varata nei tempi emergenziali, deve sottostare. L'A. passa in rassegna i Principles dell'ELI e si sofferma sulla particolare idea di "stato di eccezione" che da essi se ne desume essere ritenuta compa…

Relazioni tra stiffness aortica ed indice di resistenza intrarenale nell’ipertensione arteriosa

2012

Per molti anni lo studio mediante eco-color-doppler dei parametri semiquantitativi emodinamici renali è stato utilizzato per rilevare le alterazioni della perfusione del rene trapiantato, per la diagnosi della stenosi dell’arteria renale o per valutare la progressione di alcune nefropatie. Più recentemente è stato osservato che tali parametri, ed in particolare l’indice di resistenza intrarenale (IR), non sono soltanto espressione della perfusione parenchimale, ma sono associati anche ad alterazioni morfo-funzionali sistemiche dell’albero vascolare. Vari studi hanno dimostrato come la stiffness aortica vada aumentando con il progressivo deterioramento della funzione renale. Tuttavia, dati c…
