Quasi-Fractional Models of Human Tendons Hereditariness
2018
In this study, the authors, after collecting a series of experimental evidences following a creep and relaxation tendon campaign, propose a non-linear model of the viscoelastic behavior of the tendons. The ligaments investigated are the patellars and the hamstrings. The analytical model proposed by the authors aims to explain the non-linear hereditary behavior of these tissues and proposes an approach with which to develop a hereditary fractional-order non-linear model.
M-mode Ultrasound Examination of Soleus Muscle in Healthy Subjects: Intra- and Inter-Rater Reliability Study
2020
Objective: M-mode ultrasound imaging (US) reflects the motion of connective tissue within muscles. The objectives of this study were to evaluate inter-rater and intra-rater reliability of soleus muscle measurements between examiners with different levels of US experience in asymptomatic subjects and to investigate the level of soleus muscle isometric activity in two positions (knee extended and knee flexed at 30°
The influence of the decompressive operation on the intracranial pressure and the pressure-volume relation in patients with severe head injuries.
1978
Measurements of intracranial pressure by ventricular catheter were performed in 47 patients with severe head injuries. Thirty-three patients with decompressive operations such as osteoclastic craniotomy and dilatation by means of duraplastic have been compared with 14 patients with closed heads with regard to volume pressure response (intracranial elasticity). This was determined either by intraventricular injection of 2 ml saline or by drainage of cerebrospinal fluid. The examination clearly shows that patients with closed heads have a much higher intracranial elasticity than patients who have decompressive operations, so that in the first group minor differences of the intracranial volume…
The challenge of using the rheumatoid arthritis diagnostic criteria in clinical practice.
2015
The new 2010 ACR/EULAR (American College of Rheumatology/European League Against Rheumatism) criteria of Rheumatoid Arthritis recently published, have been released to classify and identify patients with early RA who could benefit from early therapy. They recommend anti-citrullinated protein antibody (ACPA) testing as an alternative criterion to Rheumatoid Factor (RF) and ACPA that were introduced together with the other classic criteria in a scoring system. We previously criticized these new criteria because of unavailable specificity and sensibility in the first paper, and the use of ACPA as dichotomous criterion (presence/absent) and alternatives to rheumatoid factor. Our previous work p…
MINIMIZING INFLIXIMAB TOXICITY IN THE TREATMENT OF INFLAMMATORY BOWEL DISEASE
2008
Abstract Background Infliximab is a widely used biological agent for the treatment of inflammatory bowel disease, and has a favorable risk/benefit ratio. Aim It is useful to know that patients treated with infliximab are exposed to developing adverse events that could be reduced with a prudent and a rational clinical approach and by optimizing the treatment protocol. Methods PubMed (including Epub) was searched in October 2006 and again in March 2007. Results The high immunogenic potential of infliximab determines the antibodies that inhibit the effect of infliximab and the appearance of subsequent acute and delayed infusion reactions. Infliximab has an immunomodulatory effect, thus increas…
Warm-Up and Hamstrings Stiffness, Stress Relaxation, Flexibility, and Knee Proprioception in Young Soccer Players
2022
Context: Nerves or fascia may limit motion in young soccer players, thereby contributing to frequent hamstring injuries. Nerve gliding exercises and self-myofascial release techniques may enhance the range of motion. Objective: The aim of this study was to compare the acute effect of foam rolling (FR) and neurodynamic nerve gliding (NDNG) on hamstring flexibility, passive stiffness, viscoelasticity and proprioception during the warm-up of soccer players. Design: Crossover study design. Setting: Research laboratory. Participants: Fifteen male soccer players on the same team (age 18.0 ± 1.4 years, body mass 76.9 ± 7.8 kg, height 183 ± 6 cm). Intervention: FR and NDNG included six sets of 45 s…
Endocannabinoid Role in Synaptic Plasticity and Learning
2009
Endocannabinoids have recently emerged as versatile modulators of synaptic transmission and can act as retrograde neurotransmitters. As they cannot be stored in synaptic vesicles, endocannabinoid signaling is believed to start ‘on-demand,’ via a stimulus-dependent synthesis from membranous precursors at the postsynaptic site. After synthesis, endocannabinoids bind presynaptically to cannabinoid type 1 (CB1) receptors, leading to a short- or long-term suppression of neurotransmitter release. CB1 receptors are present in a plethora of different synaptic connections in the brain. Electrophysiological and behavioral analyses of mutant mice lacking CB1 receptors and of pharmacologically treated …
Chapter 31 Transcranial magnetic stimulation studies of contralesional space attention deficits
2002
Publisher Summary The power of transcranial magnetic stimulation (TMS) to disrupt and modulate the neural activity in focal brain regions has provided researchers in this field a promising tool to empirically test specific neuropsychological models and constructs of contralesional space attention deficits. A group of studies has used TMS to transiently disrupt the cortical activity of the focal brain areas in normal subjects to replicate the effects of neurological lesions. This chapter discusses a number of studies, using single-pulse, paired-TMS, and repetitive TMS (rTMS) and different experimental paradigms that show how this technique can be of fundamental importance, in elucidating the…
Music Cities. Estrategias para el desarrollo de la economía de la música
2016
El concepto de Music City está adquiriendo relevancia paralelamente al interés sobre el impacto económico de la cultura, especialmente del sector musical comercial, y su creciente importancia en la planificación urbanística. Con la política local y regional postcrisis en el punto de mira, la gestión cultural apoyada en una investigación apropiada posibilita el desarrollo de una estrategia musical que aproveche los recursos creativos e industriales del territorio. Coordinando a las instituciones públicas, la iniciativa privada y la ciudadanía, esta especialización estratégica genera beneficios transversales para la ciudad, aumentando también su atractivo para visitantes y residentes. The con…
The unspoken pressure of tradition : East Asian classical musicians in western classical music
2013
Itäaasialaisia klassisia muusikoita käsittelevät artikkelit ovat olleet yleisiä eurooppalaisissa klassisen musiikin lehdissä siitä lähtien kun itäaasialaiset alkoivat yhä suuremmassa määrin voittaa kansainvälisiä musiikkikilpailuita ja luoda kansainvälistä uraa 1900-luvun viimeisinä vuosikymmeninä. Läntinen taidemusiikki on kansainvälistymässä aikana, jolloin pelot klassisen musiikin kuolemasta ovat myös päässeet otsikoihin Euroopassa. Itäaasialaiset muusikot työskentelevät kompleksisella kulttuurien kentällä, jossa heidän muusikkoutensa on jatkuvasti arvostelun alaisena. Tämän tutkimuksen tarkoitus oli saada selville, miten itäaasialaiset klassiset muusikot ja heidän kulttuurinen identitee…
