ABSTRACT During gastrulation, embryonic cells become specified into distinct germ layers. In mouse, this continues throughout somitogenesis from a population of bipotent stem cells called neuromesodermal progenitors (NMps). However, the degree of self-renewal associated with NMps in the fast-developing zebrafish embryo is unclear. Using a genetic clone-tracing method, we labelled early embryonic progenitors and found a strong clonal similarity between spinal cord and mesoderm tissues. We followed individual cell lineages using light-sheet imaging, revealing a common neuromesodermal lineage contribution to a subset of spinal cord tissue across the anterior-posterior body axis. An initial pop…
Validation of Using Smartphone Built-In Accelerometers to Estimate the Active Energy Expenditures of Full-Time Manual Wheelchair Users with Spinal Co…
2021
[EN] This study aimed to investigate the validity of using built-in smartphone accelerometers to estimate the active energy expenditures of full-time manual wheelchair users with spinal cord injury (SCI). Twenty participants with complete SCI completed 10 5-min daily activities that involved the upper limbs, during which their oxygen consumption and upper limb activity were registered using a portable gas analyzer and a smartphone (placed on the non-dominant arm), respectively. Time series of 1-min averaged oxygen consumption and 55 accelerometer variables (13 variables for each of the four axes and three additional variables for the correlations between axes) were used to estimate three mu…
Diferenças de sexo no uso de estratégias de enfrentamento em pessoas com lesão medular
2017
12 Páginas Objetivo: profundizar en la experiencia de afrontamiento en personas con lesión medular (LM), teniendo en cuenta tanto el afron- tamiento actual como el afrontamiento durante momentos iniciales tras sufrir la LM. Materiales y métodos: estudio transversal de encuesta. Participaron 127 personas con LM de larga evolución, 95 hombres y 32 mujeres. Los datos fueron recogidos por medio de un cuestionario online con información sociodemográfica y el Cuestionario de Afrontamiento del Estrés (CAE). Se han realizado análisis descriptivos, pruebas t de Student y análisis multivariados de la varianza (Manovas) Resultados: las comparaciones intrasujetos muestran que la estrategia de focalizac…
Impact of COVID-19 on the self-reported physical activity of people with complete thoracic spinal cord injury full-time manual wheelchair users
2021
Coronavirus SARS-CoV-2; COVID-19; 2019-nCoV; Activitat física; Lesió medul·lar Coronavirus SARS-CoV-2; COVID-19; 2019-nCoV; Actividad física; Lesión de la médula espinal Coronavirus SARS-CoV-2; COVID-19; 2019-nCoV; Physical activity; Spinal cord injury Context The emergence of COVID-19 caused a new public health crisis, leading to major changes in daily life routines, often including physical activity (PA) levels. The main goal of this study was to analyze the differences in self-reported physical activity of people with complete spinal cord injuries between the time prior to the COVID-19 lockdown and the lockdown period itself. Methods A sample of 20 participants with complete thoracic spi…
Pedaleo de brazos en personas con lesión medular, parálisis cerebral o ataxia cerebelosa: Parámetros fisiológicos. [Armcrank pedaling in persons with…
2016
espanolLos desordenes neurologicos generan afectacion fisica y derivan en sedentarismo, enfermedades coronarias y obesidad o diabetes, reduciendo tanto la esperanza como la calidad de vida. La oferta de actividad fisica adaptada es escasa por falta de informacion especifica sobre la forma de adecuarlo y dosificarlo a las personas que presentan estos desordenes. Con el fin de comparar el efecto del ejercicio de pedaleo de brazos sobre la respuesta fisiologica y la percepcion del esfuerzo, en 8 personas con lesion medular, 4 con paralisis cerebral y 4 con ataxia de Friedreich, se analizo su respuesta fisiologica, asi como su percepcion subjetiva al esfuerzo, frente a un grupo Control (16 part…
Balance Perturbations as a Measurement Tool for Trunk Impairment in Cross-Country Sit Skiing
2018
In cross-country sit-skiing, the trunk plays a crucial role in propulsion generation and balance maintenance. Trunk stability is evaluated by automatic responses to unpredictable perturbations; however, electromyography is challenging. The aim of this study was to identify a measure to group sit-skiers according to their ability to control the trunk. Seated in their competitive sit-ski, 10 male and 5 female Paralympic sit-skiers received 6 forward and 6 backward unpredictable perturbations in random order. k-means clustered trunk position at rest, delay to invert the trunk motion, and trunk range of motion significantly into 2 groups. In conclusion, unpredictable perturbations might quantif…
Corticospinal Tract Integrity and Long-Term Hand Function Prognosis in Patients With Stroke
2019
Background: The restoration of hand function is an important goal for patients with stroke. This study investigated the relationship between corticospinal tract (CST) integrity and the functional status of the hand in patients with stroke 6 months after onset and evaluated which of the following values would be useful for predicting hand function: fiber number (FN), fractional anisotropy (FA) at the mid-pons, and FA at the pontomedullary junction. Methods: The present retrospective cross-sectional observational study assessed 44 patients with stroke who were able to walk without using a walking aid or orthosis. The final hand function results were classified into three groups: no recovery (…
Wheelchair half-marathon and marathon performance: The ‘Oita International Wheelchair Marathon’ 1983-2011
2013
Knechtle, B. & Lepers, R. (2013). Wheelchair half-marathon and marathon performance ‐ the ‘Oita International Wheelchair Marathon’ 1983-2011. J. Hum. Sport Exerc., 8(4), pp.974-985. We compared participation and performance trends of individuals with disabilities competing in the half- and full-marathon in the ‘Oita International Wheelchair Marathon’ from 1981 to 2011. The performance times decreased during the 1980’s until the middle 1990’s and stabilized thereafter for both half-marathoners and marathoners. The mean top five overall finishers times were 0:52±0:07 h:min for half-marathoners and 1:36 ±0:11 h:min for marathoners, respectively. The mean age of the finishers increased signific…

In Vivo Reprogramming for Brain and Spinal Cord Repair.
2015
AbstractCell reprogramming technologies have enabled the generation of various specific cell types including neurons from readily accessible patient cells, such as skin fibroblasts, providing an intriguing novel cell source for autologous cell transplantation. However, cell transplantation faces several difficult hurdles such as cell production and purification, long-term survival, and functional integration after transplantation. Recently,in vivoreprogramming, which makes use of endogenous cells for regeneration purpose, emerged as a new approach to circumvent cell transplantation. There has been evidence forin vivoreprogramming in the mouse pancreas, heart, and brain and spinal cord with …
