FFR in a Bypass

2016

FFR can be used to determine whether by-pass lesions are significant. In this case, an additional complication was the fact that the lesion was placed at the ostium of the graft: in this case, it is important to retract the guiding catheter to avoid wedging.

The Italian dementia with Lewy bodies study group (DLB-SINdem): toward a standardization of clinical procedures and multicenter cohort studies design

2017

Dementia with Lewy bodies (DLB) causes elevated outlays for the National Health Systems due to high institutionalization rate and patients' reduced quality of life and high mortality. Furthermore, DLB is often misdiagnosed as Alzheimer's disease. These data motivate harmonized multicenter longitudinal cohort studies to improve clinical management and therapy monitoring. The Italian DLB study group of the Italian Neurological Society for dementia (SINdem) developed and emailed a semi-structured questionnaire to 572 national dementia centers (from primary to tertiary) to prepare an Italian large longitudinal cohort. The questionnaire surveyed: (1) prevalence and incidence of DLB; (2) clinical…

Removal of failed crown and bridge

2011

Crown and bridge have life span of many years but they fail for a number of reasons. Over the years, many devices have been designed to remove crowns and bridges from abutment teeth. While the removal of temporary crowns and bridges is usually very straightforward, the removal of a definitive cast crown with unknown cement is more challenging. Removal is often by destructive means. There are a number of circumstances, however, in which conservative disassembly would aid the practitioner in completing restorative/endodontic procedures. There are different mechanisms available to remove a failed crown or bridge. But there is no information published about the classification of available syste…

Graphic representation of data resulting from measurement comparison trials in cataract and refractive surgery.

2003

* BACKGROUND AND OBJECTIVES: The evaluation of new diagnostic measurement devices allows intraindividual comparison with an established standard method. However, reports in journal articles often omit the adequate incorporation of the intraindividual design into the graphic representation. * PATIENTS AND METHODS: This article illustrates the drawbacks and the possible erroneous conclusions caused by this misleading practice in terms of recent method comparison data resulting from axial length measurement in 220 consecutive patients by both applanation ultrasound and partial coherence interferometry. * RESULTS: Graphic representation of such method comparison data should be based on boxplots…

A Multi-Phase Decode-and-Forward Transmission Protocol in Cognitive Relay Networks: Outage Analysis and Relay Power Allocation

2015

Consider an underlay cognitive relay network with multiple source and destination pairs and that a decode-and-forward scheme is adopted at the relay. We propose a multi-phase transmission protocol in this paper which involves cooperation among source, relay and destination nodes. Given perfect interference elimination before decoding at the destination nodes, we derive closed-form expressions for outage probability calculation over Rayleigh fading channels. Furthermore, the optimal relay power allocation factor which leads to minimal outage probability is determined. Numerical results reveal the conditions under which satisfactory performance can be achieved based on the proposed scheme.

Efficacy of self-designed intraoral appliances in prevention of cheek, lip and tongue bite after local anesthesia administration in pediatric patients

2018

Background The occurrence of self-inflicted soft tissue injuries following administration of local anesthesia in pediatric patients who have received dental treatment has been reported. Aim: To evaluate the attitudes and knowledge regarding cheek, lip, and tongue bite post administration of local anesthesia among dental practitioners in Saudi Arabia. Additionally, the efficacies of three types of intraoral appliances on the prevention of self-harm were evaluated in pediatric patients. Material and methods A total of 301 practitioners were provided with a questionnaire consisting of 9 items. In addition, three types of intraoral appliances made of polyethylene terephthalate were designed as …

5-Fluorouracil: various kinds of loaded liposomes: encapsulation efficiency, storage stability and fusogenic properties

1993

Abstract This paper describes the optimization of 5-fluorouracil (5-FU) loaded liposome formulations. Four different preparation procedures were carried out, obtaining two types of multilamellar vesicles (MLVs), stable plurilamellar vesicles (SPLVs) and large unilamellar vesicles (LUVs). In this study various phospholipids were used to prepare liposomes. The lipid mixtures containing diplamitoylphosphatidylserine seemed the best for biological 5-FU delivery by presenting better encapsulation efficiency parameters, serum and storage stability, and fusogenic properties, which are an important factor prerequisite for in vivo liposome-cell interaction. The presence of cholesterol in the liposom…

Design and validation of the literary competence battery (LBC)

2019

The objective of this work is to present the process of design and validation of the Literary Competence Battery (BCL). The Battery consists of three scales: Literary Concepts Scale (ECL), Literary Procedures Scale (EPL) and Attitudes towards Literature Scale (EAL). The acquisition of Literary Competence (CL) is the main objective of the so-called Literary Education. However, there are few methods to measure this competence and most of them present practical problems that limit their standardization. A total of 221 adolescents participated in the design and validation process. Studies were conducted on the properties of the tests including measures of reliability, difficulty of the items, a…

Extracellular Matrix Molecular Remodeling in Human Liver Fibrosis Evolution

2016

Chronic liver damage leads to pathological accumulation of ECM proteins (liver fibrosis). Comprehensive characterization of the human ECM molecular composition is essential for gaining insights into the mechanisms of liver disease. To date, studies of ECM remodeling in human liver diseases have been hampered by the unavailability of purified ECM. Here, we developed a decellularization method to purify ECM scaffolds from human liver tissues. Histological and electron microscopy analyses demonstrated that the ECM scaffolds, devoid of plasma and cellular components, preserved the three-dimensional ECM structure and zonal distribution of ECM components. This method has been then applied on 57 l…
