A Multipurpose Instrument To Measure the Vitreous Properties of Charged Colloidal Solids

2001

We present a new high-precision light-scattering setup to study the properties of colloidal solids. It combines static light scattering, dynamic light scattering, and torsional resonance spectroscopy with a flexible and reliable preparational procedure. All three experiments can be performed quasi-simultaneously on the same mechanically undisturbed sample. Thus, unequivocal identification of glassy behavior in a comprehensive characterization dependent on interaction parameters becomes possible. A detailed description of the mechanics is given. We thoroughly tested the new apparatus on dilute colloidal samples and against commercial reference instruments. We performed a first systematic ser…

Changes in Chemokines and Chemokine Receptors Expression in a Mouse Model of Alzheimer's Disease

2018

The amyloid precursor protein plus presenilin-1 (APP/PS1) mice are a frequently-used model for Alzheimer's disease studies (AD). However, the data relevant to which proteins are involved in inflammatory mechanism are not sufficiently well-studied using the AD mouse model. Using behavioral studies, quantitative RT-PCR and Western-blot techniques, significant findings were determined by the expression of proteins involved in inflammation comparing APP/PS1 and Wild type mice. Increased GFAP expression could be associated with the elevation in number of reactive astrocytes. IL-3 is involved in inflammation and ABDF1 intervenes normally in the transport across cell membranes and both were found …

Pullulan and dextran: uncommon composition dependent Flory-Huggins interaction parameters of their aqueous solutions.

2008

Vapor pressure measurements were performed for aqueous solutions of pullulan ( M w 280 kg/mol) and dextran ( M w 60 and 2100 kg/mol, respectively) at 25, 37.5, and 50 degrees C. The Flory-Huggins interaction parameters obtained from these measurements, plus information on dilute solutions taken from the literature, show that water is a better solvent for pullulan than for dextran. Furthermore, they evince uncommon composition dependencies, including the concurrent appearance of two extrema, a minimum at moderate polymer concentration and a maximum at high polymer concentration. To model these findings, a previously established approach, subdividing the mixing process into two clearly separa…

Determination of sialic acid and gangliosides in biological samples and dairy products: A review

2009

Gangliosides are sphingolipids containing one or more moieties of sialic acid in their structure. Both gangliosides and sialic acid are bioactive compounds related to animal physiology. Due to their biological relevance, analytical methods adapted to each type of matrix have been developed over time. The present study reviews the main methods applied to the analysis of sialic acid and gangliosides in biological samples and dairy products.

Così vicina così lontana, New Graphic Design in Cina

2009

Per molti la Cina è un paese davvero sconosciuto, imperscrutabile, di difficile comprensione, così come i suoi abitanti, disseminati con numeri quasi impronunciabili su un territorio talmente vasto che è persino difficile da immaginare. Sconosciuto e affascinante, di cui vorremmo comprenderne meglio la cultura, ma la cui lingua è per molti un ostacolo invalicabile da superare, così come l’inglese per la maggior parte dei cinesi. C’è un campo però in cui le parole assumono il valore di immagine e le immagini quello di parole di più facile comprensione perché slegate, seppur non completamente, da uno specifico sistema linguistico e culturale. È il settore del graphic design, una disciplina pr…

L’assedio di Palermo del 1071-1072 nei «Gesta Roberti Wiscardi» di Guglielmo il Pugliese

2021

L’intervento si propone di mettere in evidenza alcune caratteristiche (compositive, ideologico-politiche, retorico-stilistiche) dei «Gesta Roberti Wiscardi» di Guglielmo il Pugliese, l’unico poema epico-storico del sec. XI-XII che tratti della conquista normanna dell’Italia meridionale. I «Gesta Roberti Wiscardi» contano 2833 esametri suddivisi in cinque libri, con un prologo e un epilogo, e si inseriscono in quel vasto ambito di poesia epico-storica (e fondamentalmente celebrativa ed encomiastica) che, dal periodo tardoantico conduce alla ricca produzione di storie e cronache versificate che costituisce una delle più ricorrenti tendenze della letteratura mediolatina durante il sec. XII (e …

«Student Voice» per la valorizzazione delle risorse personali

2017

Negli ultimi dieci anni, un nuovo movimento di opinione in campo educativo si è diffuso in Italia per stimolare i responsabili delle politiche educative e gli insegnanti di ogni ordine e grado dell’istruzione ad ascoltare attentamente le voci, nonché i bisogni e gli interessi di tutti gli studenti. Si tratta del movimento «Student Voice», nato negli anni Novanta nel Regno Unito e diffusosi in alcuni Paesi di area anglofona (USA, Canada, Australia). Questo movimento sostiene la partecipazione attiva e responsabile di tutti gli studenti ai processi formativi che si attivano nelle scuole e nelle università: nello specifico, questa partecipazione si esplica nella didattica in aula, nelle ricerc…

A blended-learning programme regarding professional ethics in physiotherapy students.

2018

Background: In the university context, assessing students’ attitude, knowledge and opinions when applying an innovative methodological approach to teach professional ethics becomes fundamental to know if the used approach is enough motivating for students. Research objective: To assess the effect of a blended-learning model, based on professional ethics and related to clinical practices, on physiotherapy students’ attitude, knowledge and opinions towards learning professional ethics. Research design and participants: A simple-blind clinical trial was performed (NLM identifier NCT03241693) (control group, n = 64; experimental group, n = 65). Both groups followed clinical practices for 8 mont…
