Validity and reliability of the CatWalk system as a static and dynamic gait analysis tool for the assessment of functional nerve recovery in small an…

2017

Introduction: A range of behavioral testing paradigms have been developed for the research of central and peripheral nerve injuries with the help of small animal models. Following any nerve repair strategy, improved functional outcome may be the most important evidence of axon regeneration. A novel automated gait analysis system, the CatWalk™, can measure dynamic as well as static gait patterns of small animals. Of most interest in detecting functional recovery are in particular dynamic gait parameters, coordination measures, and the intensity of the animals paw prints. This article is designed to lead to a more efficient choice of CatWalk parameters in future studies concerning the functio…

Impact of t-PA administration on brain BDNF levels in physiological conditions and in circulating BDNF levels in ischemic conditions : Human and anim…

2014

Our objective was to test the hypothesis that the beneficial effect of the administration of the recombinant form of tissue plasminogen activator (rt-PA) in ischemic stroke patient not only results from its fibrinolytic activity but also from its ability to increase brain-derived neurotrophic factor (BDNF) in the brain. To this end, we conducted an initial study to evaluate the effect of rt-PA on brain BDNF levels in healthy animals. In a second study, we investigated the effect of rt-PA on serum BDNF levels in ischemic stroke patients and in animals subjected to permanent focal cerebral ischemia. Blood samples were obtained from patient on admission (D0), D1, D7 and D90 after stroke and in…

Automatic fuzzy classification of the washout curves from magnetic resonance first-pass perfusion imaging after myocardial infarction.

2005

International audience; Abstract: Objectives: We sought to investigate the diagnostic ability of cardiac magnetic resonance imaging (MRI) perfusion in acute reper-fused myocardial infarction. The study used fuzzy logic to automatically classify signal intensity-time curves from myocardial segments into 3 categories: normal, hypointense, and Hyperintense. Materials and Methods: Thirty-eight patients with myocardial infarction underwent short-axis cine-MRI and contrast-enhanced MRI to provide data on wall thickening and the transmural extent of infarction. Of these, 17 had a second cardiac MRI to ascertain the functional recovery in each segment. Results: The fuzzy logic based classification …

Impaired conflict resolution and vigilance in euthymic bipolar disorder.

2015

Abstract Difficulty attending is a common deficit of euthymic bipolar patients. However, it is not known whether this is a global attentional deficit or relates to a specific attentional network. According to the attention network approach, attention is best understood in terms of three functionally and neuroanatomically distinct networks-alerting, orienting, and executive control. In this study, we explored whether and which of the three attentional networks are altered in euthymic Bipolar Disorder (BD). A sample of euthymic BD patients and age-matched healthy controls completed the Attention Network Test for Interactions and Vigilance (ANTI-V) that provided not only a measure of orienting…

The treatment of wrist fractures with Epibloc System

2011

BACKGROUND Fractures of the distal extremity of the radius are the most common bone lesions of the superior extremity of the body, representing 17% of the fractures treated in First Aid facilities. The restoration of anatomical relationships in the radiocarpal joint is considered to be a prerequisite for good functional recovery. There are numerous methods of treatment of these fractures. The Epibloc system is a percutaneous endomedullary synthesis alternative to the plaster cast in wrist fracture treatment. MATERIALS AND METHODS The authors describe their experience with 81 fractures (63 type A2-3 fractures and 18 type C1) of the wrist treated with the Epibloc System (ES). The results were…

0229: Alterations of cardiac function induced by postnatal overfeeding can be reversed by moderate diet restriction

2014

Postnatal overfeeding (OF) in rodents induces a permanent moderate increase in body weight, metabolic disorders and progressive alterations of cardiac function. Our aim was to determine whether moderate diet restriction could restore cardiac function in mature overfed mice. Immediately after birth, litters of C57BL/6 mice were either maintained at nine (normal-fed group, NF), or reduced to three in order to induce OF. At weaning, mice of both groups received a standard diet ad libitum (AL). At 6 months of age, half of the OF mice were assigned to a moderate 20% calorie restriction (CR, OF-CR) for one month, while NF and the other half of the OF mice continued to eat ad libitum (NF-AL, OF-AL…

Translating intracarotid artery transplantation of bone marrow-derived NCS-01 cells for ischemic stroke: Behavioral and histological readouts and mec…

2019

Abstract The present study used in vitro and in vivo stroke models to demonstrate the safety, efficacy, and mechanism of action of adult human bone marrow‐derived NCS‐01 cells. Coculture with NCS‐01 cells protected primary rat cortical cells or human neural progenitor cells from oxygen glucose deprivation. Adult rats that were subjected to middle cerebral artery occlusion, transiently or permanently, and subsequently received intracarotid artery or intravenous transplants of NCS‐01 cells displayed dose‐dependent improvements in motor and neurological behaviors, and reductions in infarct area and peri‐infarct cell loss, much better than intravenous administration. The optimal dose was 7.5 × …

The effect of two physiotherapy approaches on physical and cognitive functions and independent coping at home in stroke rehabilitation. A preliminary…

2007

Activating physiotherapy was used to support the principle of post stroke functional recovery as a learning process which requires both cognitive and physical actions. The purpose of the present preliminary study was to examine the influence of activating physiotherapy on stroke patients' cognitive and physical functions and independent living at home compared with traditional treatment over a 12-month follow-up.The 40 patients who received activating physiotherapy were compared with 40 patients receiving traditional therapy. Patients' physical functional capacity was measured one week and 12 months post stroke with the Barthel Index (BI), 10-m gait speed, the Postural Control and Balance f…

Functional reorganization of the attentional networks in low-grade glioma patients: a longitudinal study.

2015

International audience; Right brain damage often provokes deficits of visuospatial attention. Although the spatial attention networks have been widely investigated in stroke patients as well as in the healthy brain, little is known about the impact of slow growing lesions in the right hemisphere. We here present a longitudinal study of 20 patients who have been undergoing awake brain surgery with per-operative line bisection testing. Our aim was to investigate the impact of tumour presence and of tumour resection on the functional (re)organization of the attention networks. We assessed patients' performance on lateralized target detection, visual exploration and line bisection before surger…
