A Structural Approach to Infer Recurrent Relations in Data

2014

Extracting knowledge from a great amount of collected data has been a key problem in Artificial Intelligence during the last decades. In this context, the word "knowledge" refers to the non trivial new relations not easily deducible from the observation of the data. Several approaches have been used to accomplish this task, ranging from statistical to structural methods, often heavily dependent on the particular problem of interest. In this work we propose a system for knowledge extraction that exploits the power of an ontology approach. Ontology is used to describe, organise and discover new knowledge. To show the effectiveness of our system in extracting and generalising the knowledge emb…

Clivaggio e shuttling nucleo-citoplasmatico della proteina Sirt1, in cellule di carcinoma mammario MDA-MB231.

2013

Sirt1 è una proteina nota per il suo ruolo di istone deacetilasi NAD+ dipendente che sembra essere coinvolta in una ampia gamma di processi cellulari, quali regolazione genica, controllo dello stato metabolico, meccanismi di sopravvivenza allo stress. Dalla letteratura emergono dati contrastanti concernenti la funzione di Sirt1 nei tumori, le vengono infatti attribuiti ruoli sia di oncogene che di soppressore tumorale, argomento fortemente dibattuto. A conferma di ciò, la localizzazione subcellulare e la funzione di Sirt1 variano nei differenti tipi cellulari (1). E’ anche noto che Sirt1 risulta frequentemente clivata in varie linee cellulari grazie ad attività proteolitiche nucleari (2). Q…

Comparing illicit drug use in 19 European cities through sewage analysis

2012

Abstract: The analysis of sewage for urinary biomarkers of illicit drugs is a promising and complementary approach for estimating the use of these substances in the general population. For the first time, this approach was simultaneously applied in 19 European cities, making it possible to directly compare illicit drug loads in Europe over a 1-week period. An inter-laboratory comparison study was performed to evaluate the analytical performance of the participating laboratories. Raw 24-hour composite sewage samples were collected from 19 European cities during a single week in March 2011 and analyzed for the urinary biomarkers of cocaine, amphetamine, ecstasy, methamphetamine and cannabis u…

Cytotoxicity of the Urokinase-Plasminogen Activator Inhibitor Carbamimidothioic Acid (4-Boronophenyl) Methyl Ester Hydrobromide (BC-11) on Triple-Neg…

2015

BC-11 is an easily synthesized simple thiouronium-substituted phenylboronic acid, which has been shown to be cytotoxic on triple negative MDA-MB231 breast cancer cells by inducing a perturbation of cell cycle when administered at a concentration equal to its ED50 at 72 h (117 μM). Exposure of cells to BC-11, either pre-absorbed with a soluble preparation of the N-terminal fragment of urokinase-plasminogen activator (uPa), or in co-treatment with two different EGFR inhibitors, indicated that: (i) BC-11 acts via binding to the N-terminus of the enzyme where uPa- and EGF receptor-recognizing sites are present, thereby abrogating the growth-sustaining effect resulting from receptor binding

Response to computer-assisted intervention in children most at risk for mathematics difficulties

2015

Evidence of an association between poor early number skills and a high risk for later difficulties in mathematics manifests a need for both early identification of risk and effective prevention of difficulties. However, only a few theory-based assessment and progress monitoring tools, and intervention methods are avail able for this purpose in Finnish pre-primary education. This thesis aimed to examine to what extent a theory-based computer-assisted intervention method (GraphoGame Math, GGM) can support early number skills development in children (6௅7-year-olds) most at risk for mathematics difficulties (MD; defined as performance below the 10th percentile). The specific aims were threefold…

Structural Features of β-Cyclodextrin Solvation in the Deep Eutectic Solvent, Reline

2020

The inherently amphiphilic nature of native cyclodextrins (CDs) determines their peculiar molecular encapsulation features, enabling applications such as targeted drug nanodelivery, aroma protection, etc. On the contrary, it may also lead to poor solubility in water and other organic solvents and to potentially detrimental flocking in these media, thus posing limitations to more extensive usage. Here we use small angle X-ray scattering to show that deep eutectic solvent reline (1:2 choline chloride:urea) succeeds in dissolving large amounts of beta-CD (at least 800 mg/mL, compared with the solubility in water of 18 mg/mL), without aggregation phenomena occurring. At the microscopic level, m…

Exercise restores decreased physical activity levels and increases markers of autophagy and oxidative capacity in myostatin/activin blocked mdx mice

2013

The importance of adequate levels of muscle size and function and physical activity is widely recognized. Myostatin/activin blocking increases skeletal muscle mass but may decrease muscle oxidative capacity and can thus be hypothesized to affect voluntary physical activity. Soluble activin receptor IIB (sActRIIB-Fc) was produced to block myostatin/activins. Modestly dystrophic mdx mice were injected with sActRIIB-Fc or PBS with or without voluntary wheel running exercise for 7 wk. Healthy mice served as controls. Running for 7 wk attenuated the sActRIIB-Fc-induced increase in body mass by decreasing fat mass. Running also enhanced/restored the markers of muscle oxidative capacity and autoph…
