Soft tissue integration of different abutment surfaces: An experimental study with histological analysis

2021

OBJECTIVE To evaluate whether abutment surface and surface bio-activation have an effect on soft tissue morphogenesis. MATERIALS AND METHODS 36 patients (36 implants) were included. Abutments were randomly divided into 4 groups (n = 9): Smooth Surface-MAChined (MAC), Ultrathin Threaded Microsurface (UTM), MAC Plasma of Argon activated (Plasma-MAC), and UTM Plasma of Argon activated (Plasma-UTM). After 2 months of healing, soft tissue samples were collected and prepared for histological analysis. The margin of the peri-implant mucosa (PM), the apical extension of the barrier epithelium (aJE), and the apical location of the abutment (AM) were identified. Significances of differences among gro…

Impairment of the modulatory role of nitric oxide on the endothelin-1-elicited contraction of cerebral arteries: a pathogenetic factor in cerebral va…

1997

OBJECTIVE: Nitric oxide (NO) and endothelin-1 (ET-1) are two endothelium-derived factors probably involved in the pathogenesis of cerebral vasospasm after subarachnoid hemorrhage (SAH). Our aim was twofold, i.e., to ascertain whether endothelial and nonendothelial NO modulates the contractile response of cerebral arteries to ET-1 and to analyze whether this relationship might be impaired after experimental SAH. METHODS: Rings of middle cerebral artery from goats in the control group and from goats with SAH were set up for isometric tension recordings. SAH was induced 3 days before the experiments by infusion of 10 ml of autologous arterial blood through a catheter previously inserted into t…

Socioemotional characteristics of minors in foster care: A comparison between the estimation of parents, teachers and children

2013

Abstract During the child's first few years, it's of fundamental importance the presence of a strong emotional base as long as it creates the possibility to open themselves to physical and social world with confidence, and as it acts as a facilitator of cognitive development. For this reason, if the family cannot ensure such base, social services are forced to resort to foster care, a resource that has a lot of difficulties, leading to different implications in the development of the child and of the foster family. It is therefore important to analyze in depth the socio-emotional variables that characterize children who are in a situation of foster care in order to provide adequate assistan…

Dietary phytoestrogens improve stroke outcome after transient focal cerebral ischemia in rats.

2006

As phytoestrogens are postulated as being neuroprotectants, we assessed the hypothesis that dietary isoflavone-type phytoestrogens are neuroprotective against ischemic stroke. Transient focal cerebral ischemia (90 min) was induced by middle cerebral artery occlusion (MCAO) following the intraluminal thread technique, both in rats fed with soy-based diet and in rats fed with isoflavone-free diet. Cerebro-cortical laser-Doppler flow (cortical perfusion, CP), arterial blood pressure, core temperature, PaO2, PaCO2, pH and glycemia were measured before, during and after MCAO. Neurological examination and infarct volume measurements were carried out 3 days after the ischemic insult. Dietary isofl…

An Extended Kalman Filter-Based Technique for On-Line Identification of Unmanned Aerial System Parameters

2015

ABSTRACT: The present article deals with the identification, at the same time, of aircraft stability and control parameters taking into account dynamic damping derivatives. Such derivatives, due to the rate of change of the angle of attack, are usually neglected. So the damping characteristics of aircraft dynamics are attributed only on pitch rate derivatives. To cope with the dynamic effects of these derivatives, authors developed devoted procedures to estimate them. In the present paper, a complete model of aerodynamic coefficients has been tuned-up to identify simultaneously the whole set of derivatives. Besides, in spite of the employed reduced order model and/or decoupled dynamics, a s…

Countering Adversarial Inference Evasion Attacks Towards ML-Based Smart Lock in Cyber-Physical System Context

2021

Machine Learning (ML) has been taking significant evolutionary steps and provided sophisticated means in developing novel and smart, up-to-date applications. However, the development has also brought new types of hazards into the daylight that can have even destructive consequences required to be addressed. Evasion attacks are among the most utilized attacks that can be generated in adversarial settings during the system operation. In assumption, ML environment is benign, but in reality, perpetrators may exploit vulnerabilities to conduct these gradient-free or gradient-based malicious adversarial inference attacks towards cyber-physical systems (CPS), such as smart buildings. Evasion attac…

Massoneria

2005

Il processo di rinnovamento interno avviato da una parte della massoneria italiana dopo l’emanazione della legge 25 gennaio 1982 n. 17 (Norme di attuazione dell’art. 18 della Costituzione in materia di associazioni segrete e scioglimento dell’associazione denominata Loggia P2) e dopo la promulgazione della nuova Costituzione dell’Ordine, firmata da Armando Corona il 18 novembre del 1984, attraversa – ancora oggi – un percorso tortuoso, travagliato e complesso. Del resto, articolata e complessa è stata, nel nostro Paese, la storia della libera muratoria, che dal dopoguerra ai giorni nostri, a più riprese, oltre a divisioni e contrasti interni, ha dovuto registrare episodi gravi di “deviazion…

Affiliation Motivational System

2016

In this chapter, the concept of affiliation is presented as a general human disposition and basic motivation. The wide range of affiliative motives is analysed in the realms of interpersonal and group dynamics. Needs on the interpersonal level include attachment, intimacy and love, while the group dynamic is analysed in terms of in-group and inter-group relations. It is argued that all needs in the realm of interpersonal and group relations are interrelated and imply the existence of the larger underlying belonging motivation. Furthermore, the chapter also postulates that the conceptualisation of the human need for belonging should also include the need for distance and, in this way, should…

Continuous play : leisure engagement in competitive fighting games and taekwondo

2023

In order to better understand the development of play and games in modern lives, this article examines two competitive leisure groups: digital fighting game players and traditional taekwondo practitioners. Drawing on qualitative offline/online interviews (n = 56) and close reading of externally documented life narratives (n = 14), we explore how the modes and motives of engagement fluctuate in competitive players over time. The study provides a new developmental approach to continuous competitive play as leisure. Our results show rather than making linear progress from ‘casual’ to ‘serious’ leisure, individuals in both groups perceive their lasting relationships with these activities gradua…
