Comparative assessment of brain activity during depth perception of stereoscopic and volumetric images

2020

Recent advancements in visualization systems have triggered a growing demand for the objective and accurate comparison of user cognitive requirements when perceiving three-dimensional images demonstrated in different ways. In this work, we present the first comparative assessment of brain activity in subjects viewing stereoscopic images and volumetric images. Electroencephalography was employed to assess the short-term changes in event related potentials and neural oscillations which were further interpreted in terms of cognitive requirements for relative depth judgments. As a result, considerably higher activity have been registered in the beta band and gamma band in case of judging relati…

Binocular, Accommodative and Oculomotor Alterations In Multiple Sclerosis: A Review

2020

Multiple sclerosis (MS) is an acquired demyelinating and inflammatory neurodegenerative disease affecting the central nervous system (CNS). Clinical and subclinical ocular disturbances occur in almost all patients with MS. The objective of this narrative review was to collect and summarize the available scientific information on oculomotor, accommodative and binocular alterations that have been reported in MS. A systematic search strategy with the following descriptors was carried out: multiple sclerosis, ocular motility disorders, internuclear ophthalmoplegia, nystagmus, vergences, fixation, pupil reflex, accommodation and stereopsis. According to the search, some oculomotor alterations w…

Improvement of quality of life during treatment with anabolic therapy: Results of a multicenter study

2012

Efficacy and safety of daily treatment with parathyroid hormone were evaluated in a typical Italian population with severe post-menopausal osteoporosis eligible to anabolic treatment (Nota 79 AIFA). Materials and methods: 204 ambulatory female patients (median age: 72.6±8.3 years; height: 155.3±6.5 cm; weight: 61.1±11.9 Kg) with severe post-menopausal osteoporosis have been enrolled in this study accordingly to summary of product characteristics and Italian reimbursement criteria for osteoporosis drugs (Nota 79 AIFA), between January 2008 and April 2009 (Last Patient Out: October 2010). 146 (71.57%) out of these patients completed the study.6 visits were planned in the study protocol: basel…

Social research evolution in management accounting : reflection using Bunge’s theory

2004

Abstract Actually Management Accounting is considered for an important group of researchers as a social science. This is a consequence of an evolution from an economic view to social-oriented perspectives. Following Mario Bunge’s theory, we establish that break point in 1980s. Until 1980s, the accounting research was dominated by an economic analysis with both utilitarian and cognitive objectives. The scientific growth was in surface , without any relevant change in the foundations of Management Accounting. The development of new concerns regarding social implications promotes a growth in-depth in the 1980s. Socio-economic analysis, both in interpretative and critical research, is developed…

Hypovitaminosis D and orthostatic hypotension: A systematic review and meta-analysis

2016

Objectives: Orthostatic hypotension is a common condition among older adults and is associated with a range of deleterious outcomes. Recently, interest has developed in hypovitaminosis D (defined as low 25 hydroxiyVitamin D levels) as a potential risk factor for orthostatic hypotension. We conducted a systematic review and meta-analysis examining the association of orthostatic hypotension between study participants with and without hypovitaminosis D, including the adjustment of potential confounders (age, sex, BMI, renal function, comorbidities, seasonality, use of antihypertensive medications, and supplementation with cholecalciferol). Methods: A systematic literature search of major elect…

Diagnostic accuracy of clinical parameters to monitor peri-implant conditions: A matched case-control study

2018

International audience; Background: The aim of this case-control study was to estimate the diagnostic accuracy of the standard clinical parameters in diagnosing healthy peri-implant tissues, peri-implant mucositis, and peri-implantitis.Methods: A case-control study was designed to compare the clinical parameters used in the diagnosis of peri-implant diseases such as: probingdepth (PD), bleeding on probing (BOP), mucosal redness (MR), suppuration (SUP), and plaque index (PI). Furthermore, the influence of patient-(sex, age) and implant-related variables (implant neck configuration, time in function after loading) were evaluated to investigate the association with the clinical findings. The i…

Response of Bone Metabolism Markers to Ice Swimming in Regular Practitioners

2021

Objective: Both exercise and cold exposure cause physiological stress and they often occur in combination. However, the effects of exercise during severe cold on variation in bone metabolism in humans have remained elusive. The aim of this study was to investigate the variations in circulating bone metabolism markers after ice swimming (IS).Methods: Eighty-seven women and men aged 42–84 years old were recruited to perform regular IS activities. Serum parathyroid hormone (PTH), total calcium (Ca2+), total phosphorus (Pi), total magnesium (Mg2+), N-terminal osteocalcin (N-MID), total propeptide of procollagen 1 (TPINP), and C-terminal telopeptide of type 1 collagen (β-CTX) were measured 30 mi…

In vitro comparison of platinum-iridium and gold tip electrodes: lesion depth in 4 mm, 8 mm, and irrigated-tip radiofrequency ablation catheters

2009

Aims We compared a newly developed irrigated gold tip electrode ablation catheter and a gold tip 4 and 8 mm catheter with the corresponding platinum–iridium (Pt) tip catheters in an in vitro setting. Methods and results In a flow chamber simulating physiological flow conditions, radiofrequency catheter ablation was performed on tissue samples of porcine endomyocardium and liver. Lesion depth, energy and temperature delivery, and popping frequency were determined. Two hundred and fifty-three ablations were conducted. Four and eight millimetre, gold tip electrode catheters produced significantly deeper lesions compared with the Pt tip electrode (liver 4 mm: 4.67 ± 1.7 vs. 2.9 ± 1.0 mm, P < 0.…
