Clinical Features and Natural History of AMD

2009

Over recent years, OCT has become an essential part of the examination in routine follow up for AMD to guide clinical practice and analyze the response to treatment. OCT examinations can clearly demonstrate the efficacy of treatment by showing regression or persistence of leakage. Moreover, alterations of the outer retinal layers can also be analyzed.

Polypoidal Choroidal Vasculopathy

Polypoidal choroidal vasculopathy does not constutute part of the classical definition of AMD, but these two en tities have a number of features in common.

Mechanical rotational thrombectomy in long femoropopliteal artery and stent occlusion in COVID-19 patient: Case report

2021

Abstract Introduction Coronavirus disease-19 (COVID-19) has been increasingly associated with thromboembolic complications. COVID-19 infection has a thrombogenic potential for stents. Herein, we report a case of stent thrombosis in diabetic obese patient COVID-19 positive where was previously released a Multilayer Flow Modulator stent (MFM) for large popliteal aneurysm. Case report A 78-year-old male was referred to our hospital for fever and acute pain in the left leg. At history, the same patient had endovascular procedure for a large symptomatic popliteal aneurysm, treated through release of three MFM. The pulmonary CT scan showed COVID-19 infection with confirm of rhino-laryngeal swab. …

Review of ultrasonic irrigation in endodontics: increasing action of irrigating solutions

2011

Introduction: Effective irrigant delivery and agitation are prerequisites for successful endodontic treatment. Ultrasonic irrigation can be performed with or without simultaneous ultrasonic instrumentation. Existing literature reveals that ultrasonic irrigation may have a very positive effect on chemical, biological and physical debridement of the root canal system as investigated in many in vitro studies. Objective: The purpose of this review article was to summarize and discuss the available information concerning ultrasonic irrigation in endodontics. Methods: This article presents an overview of ultrasonic irrigation methods and their debridement efficacy. In this paper the relevant lite…

Comparison of the standing balance between pole vaulters and soccer players in preseason and postseason

2020

Background and Study Aim: Static is crucial in the maintaining the position of the body’s center of gravity vertically over the base of support. Many sport disciplines require effective balance system. However, the efficiency of the system differs based on the sport discipline. The aim of the study was to examine balance system efficiency in pole vaulters and soccer players. Additionally, the analysis of pre and postseason balance system efficiency was performed in pole vaulters and soccer players as well.
 Material and Methods: To asses static balance system efficiency five pole vaulters and six soccer players were examined. A balance platform was used for open eyes test, close eyes t…

Advances in surfaces and osseointegration in implantology. Biomimetic surfaces

2015

The present work is a revision of the processes occurring in osseointegration of titanium dental implants according to different types of surfaces -namely, polished surfaces, rough surfaces obtained from subtraction methods, as well as the new hydroxyapatite biomimetic surfaces obtained from thermochemical processes. Hydroxyapatite’s high plasma-projection temperatures have proven to prevent the formation of crystalline apatite on the titanium dental implant, but lead to the formation of amorphous calcium phosphate (i.e., with no crystal structure) instead. This layer produce some osseointegration yet the calcium phosphate layer will eventually dissolve and leave a gap between the bone and …

A magnetic look into the protecting layer of Au25 clusters

2016

The field of molecular metal clusters protected by organothiolates is experiencing a very rapid growth. So far, however, a clear understanding of the fine interactions between the cluster core and the capping monolayer has remained elusive, despite the importance of the latter in interfacing the former to the surrounding medium. Here, we describe a very sensitive methodology that enables comprehensive assessment of these interactions. Pulse electron nuclear double resonance (ENDOR) was employed to study the interaction of the unpaired electron with the protons of the alkanethiolate ligands in four structurally related paramagnetic Au25(SR)0 18 clusters (R ¼ ethyl, propyl, butyl, 2-methylpro…

Molecular nanostructures on ferromagnetic metals for spintronics

2017

El objetivo principal de esta tesis ha sido el estudio de la funcionalización de superficies ferromagnéticas mediante la formación de monocapas moleculares autoensambladas, (SAMs, self-assembled monolayers) con el fin de conseguir procesos sencillos y fiables para la preparación de interfaces híbridas aplicables en dispositivos de espintrónica molecular. La investigación se ha centrado en la funcionalización de materiales ferromagnéticos, concretamente el cobalto y la aleación de níquel:hierro conocida como Permalloy. Las propiedades magnéticas y de polarización de espín de estos metales ferromagnéticos se mantienen a temperatura ambiente, lo que los hace muy interesantes para su aplicación…
