POST-THALAMOTOMY NEUROFUNCTIONAL FINDINGS ON PATIENTS TREATED WITH TRANS-CRANIAL MAGNETIC RESONANCE GUIDED FOCUSED ULTRASOUND SURGERY (TCMRGFUS): PRE…
2015
BACKGROUND AND PURPOSE: We present functional connectivity (FC) changes found in the very first patients treated with the first Italian installation of a trans-cranial MRI-guided Focused Ultrasound Surgery (tcMRgFUS) certified system for functional neurosurgery. TcMRgFUS is a promising new technique for non-invasive treatment of neurologic disorders such as Essential Tremor, tremor associated to Parkinson's Disease and Neuropathic Pain. TcMRgFUS is able to focally target and destroy specific regions in the brain through intact skull, by using a high intensity focused ultrasound beam. Resting state functional Magnetic Resonance Imaging (RS-fMRI) analyses focuses on spontaneous low frequency …
Contributions to risk injury evaluation of human skin contact caused by welding technology in mechanical engineering a company
2017
Assembly by welding is a very important pollutant technological process, mainly of the atmosphere and soil. The formation of gas in welding process is the result of electrodes, fluxes burning, formation of fused bath and welded seam. A large number of human operators feels different adverse effects on health. Most problems appears in respiratory system and include bronchitis, respiratory irritation, fever caused by smoke, changes in lung function, decreased immunity to infection and a possible increase of lung cancer risk. Very little information are available about effects on the organism and skin after exposure to fumes from welding, therefore. In this order, this paper do a risk assessme…
ADHD Symptoms and peer problems: Mediation of executive function and theory of mind
2017
Background: The social maladjustment suffered by many children with attention defi cit hyperactivity disorder (ADHD) is maintained over time, increasing the risk of subsequent adverse outcomes. The objectives of the study were to explore the mechanisms that operate between ADHD symptoms and social problems with peers, considering the mediation of FE and ToM. Method: 35 children with ADHD and 37 with typical development matched in age and IQ were compared. Parents assessed ToM skills and relationships with peers, and teachers provided EF ratings. Results: The analyses showed statistically signifi cant indirect mediation effects of EF in the relationship between ADHD symptoms and problems in …

Understanding the White-Emitting CaMoO4 Co-Doped Eu3+, Tb3+, and Tm3+ Phosphor through Experiment and Computation
2019
In this article, the synthesis by means of the spray pyrolysis method, of the CaMoO4 and rare-earth cation (RE3+)-doped CaMoO4:xRE3+ (RE3+ = Eu3+, Tb3+, and Tm3+; and x = 1, 2, and 4% mol) compounds, is presented. The as-synthesized samples were characterized using X-ray diffraction, Rietveld refinement, field emission scanning electron microscopy (FE-SEM), Raman spectroscopy, and photoluminescence (PL) spectroscopy. To complement and rationalize the experimental results, first-principles calculations, at the density functional theory level, have been performed to analyze the band structure and density of states. In addition, a theoretical method based on the calculations of surface energie…
A Completeness Proof for a Regular Predicate Logic with Undefined Truth Value
2023
We provide a sound and complete proof system for an extension of Kleene's ternary logic to predicates. The concept of theory is extended with, for each function symbol, a formula that specifies when the function is defined. The notion of "is defined" is extended to terms and formulas via a straightforward recursive algorithm. The "is defined" formulas are constructed so that they themselves are always defined. The completeness proof relies on the Henkin construction. For each formula, precisely one of the formula, its negation, and the negation of its "is defined" formula is true on the constructed model. Many other ternary logics in the literature can be reduced to ours. Partial functions …
The relationship between endothlial ABD erectile dysfunction, levels of testosterone and cardiovascular events in the follow-up
2016
Background: Clinical and experimental evidence suggest that testosterone levels play a role in cardiac and vascular pathology. A long history of observational studies investigating serum testosterone level and cardiovascular risks, specifically mortality, reveals important associations between low testosterone and mortality, while higher serum testosterone level appear to be predictive in the majority of studies. On the other hand, it is well documented and accepted that endothelial dysfunction is expression of preclinical atherosclerosis and it is associated with an increased amount of CV events in the follow-up. Erectile dysfunction is also an early manifestation of arteriosclerosis assoc…
Testosterone levels are directly related with erectile function and endothelial function in men with intermediate risk according to the Framingham sc…
2014
Background. The value of testosterone levels and erectile dysfunction (ED) as early markers of atherosclerosis is not well understood. Objectives. To analyze the relationship between plasma testosterone levels in men with both endothelial function (F) and ED. Methods. We enrolled 802 asymptomatic, intermediate cardiovascular risk patients, according to the Framingham Risk Score, aged 40 to 80 years, who underwent the study of EF, evaluation of ED and dosage of plasma testosterone. Results. At linear regression, EF (t=9.40; 95% CI from 0.9318 to 1.4234; p<0.0001) and erectile function (t=8.96; 95% CI from 0.7642 to 1.1932; p<0.0001) statistically increased with increasing levels of testoster…
The Role of Textured Material in Supporting Perceptual-Motor Functions
2013
Simple deformation of the skin surface with textured materials can improve human perceptual-motor performance. The implications of these findings are inexpensive, adaptable and easily integrated clothing, equipment and tools for improving perceptual-motor functionality. However, some clarification is needed because mixed results have been reported in the literature, highlighting positive, absent and/or negative effects of added texture on measures of perceptual-motor performance. Therefore the aim of this study was to evaluate the efficacy of textured materials for enhancing perceptual-motor functionality. The systematic review uncovered two variables suitable for sub-group analysis within …
