Twitch interpolation during equal-intensity voluntary and electrically-evoked isometric contractions of the quadriceps muscle

2005

It has been suggested that, during contractions triggered by electrical stimulation, motor units are recruited in a reversed sequence compared to voluntary contraction. The classic view is that lar...

Biomechanical evaluation of a new treatment method for distal tibia fractures

2015

Distal tibial fractures are often the result of high-energy impacts combined with excessive soft tissue injury. Treatment options include either open reduction and internal fixation usually as a mi...

Intra-Dialytic Electrostimulation of Leg Extensors May Improve Exercise Tolerance and Quality of Life in Hemodialyzed Patients

2011

Hemodialyzed (HD) patients with end-stage renal disease (ESRD) exhibit lower fitness as a consequence of chronic uremic changes that trigger various structural, metabolic, and functional abnormalities in skeletal muscles. The aim of this randomized study was to compare the effect of rehabilitation (RHB) training on a bicycle ergometer and electromyostimulation (EMS) of leg extensors in HD patients with ESRD. Thirty-two HD patients (18 men/14 women; mean age 61.1 ± 8.8 years) were randomized into three groups: (i) exercise training (ET; n = 11) on bicycle ergometer 2 × 20 min; (ii) EMS (n = 11) where stimulation (10 Hz) of leg extensors was applied for 60 min; and (iii) controls (CON; n = 10…

Hepatitis C virus infection in hemodialyzed patients.

2007

In spite of our present improved knowledge of the epidemiology and pathways of contamination of the hepatitis C virus (HCV), infection still remains a public health problem. One category of patients who have suffered greatly from the consequences of HCV infection is certainly that of hemodialysis patients. In the past, in fact, their need for transfusions exposed these patients to infection and, as a result, subjects on dialysis for over 15 years are today paying the price for those inevitable transfusions, as the virus and its pathways of contagion were unknown then. However, still today, albeit at a much lower prevalence, even subjects with a shorter dialysis age present a higher prevalen…

Endovascular management of a large aneurysm of the superior vena cava involving internal thoracic vein with remodeling technique

2016

International audience; We report a case describing endovascular treatment of a large aneurysm of the superior vena cava involving internal thoracic vein. The goal of this case report is to highlight the contributing role of embolization with remodeling technique in such an exceptional condition.

Intravenous SPION-labeled adipocyte-derived stem cells targeted to the brain by magnetic attraction in a rat stroke model: An ultrastructural insight…

2021

Abstract Mesenchymal stem cell therapy after stroke is a promising option investigated in animal models and clinical trials. The intravenous route is commonly used in clinical settings guaranteeing an adequate safety profile although low yields of engraftment. In this report, rats subjected to ischemic stroke were injected with adipose-derived stem cells (ADSCs) labeled with superparamagnetic iron oxide nanoparticles (SPIONs) applying an external magnetic field in the skull to retain the cells. Although most published studies demonstrate viability of ADSCs, only a few have used ultrastructural techniques. In our study, the application of a local magnetic force resulted in a tendency for hig…

Correction: One-pot synthesis of a new generation of hybrid bisphosphonate polyoxometalate gold nanoparticles as antibiofilm agents

2019

A reduced polyoxovanadate functionalized with bisphosphonate molecules was synthesized and used to prepare in one step hybrid organic–inorganic polyoxometalate decorated gold nanoparticles. These new composites were shown to strongly inhibit P. aeruginosa and S. epidermidis biofilm growth, with the three components constituting the nanoparticles (Au0 core, vanadium and alendronate) acting synergistically.

A Unified Theory of Psychophysical Laws in Auditory Intensity Perception.

2020

Psychophysical laws quantitatively relate perceptual magnitude to stimulus intensity. While most people have accepted Stevens's power function as the psychophysical law, few believe in Fechner's original idea using just-noticeable-differences (jnd) as a constant perceptual unit to educe psychophysical laws. Here I present a unified theory in hearing, starting with a general form of Zwislocki's loudness function (1965) to derive a general form of Brentano's law. I will arrive at a general form of the loudness-jnd relationship that unifies previous loudness-jnd theories. Specifically, the "slope," "proportional-jnd," and "equal-loudness, equal-jnd" theories, are three additive terms in the ne…
