Effect of Training-Induced Changes in Achilles Tendon Stiffness on Muscle–Tendon Behavior During Landing
2018
During rapid deceleration of the body, tendons buffer part of the elongation of the muscle–tendon unit (MTU), enabling safe energy dissipation via eccentric muscle contraction. Yet, the influence of changes in tendon stiffness within the physiological range upon these lengthening contractions is unknown. This study aimed to examine the effect of training-induced stiffening of the Achilles tendon on triceps surae muscle–tendon behavior during a landing task. Twenty-one male subjects were assigned to either a 10-week resistance-training program consisting of single-leg isometric plantarflexion (n = 11) or to a non-training control group (n = 10). Before and after the training period, plantarf…
Training-induced increase in Achilles tendon stiffness affects tendon strain pattern during running
2019
Background During the stance phase of running, the elasticity of the Achilles tendon enables the utilisation of elastic energy and allows beneficial contractile conditions for the triceps surae muscles. However, the effect of changes in tendon mechanical properties induced by chronic loading is still poorly understood. We tested the hypothesis that a training-induced increase in Achilles tendon stiffness would result in reduced tendon strain during the stance phase of running, which would reduce fascicle strains in the triceps surae muscles, particularly in the mono-articular soleus. Methods Eleven subjects were assigned to a training group performing isometric single-leg plantarflexion co…
Medial Gastrocnemius Muscle Architecture Is Altered After Exhaustive Stretch-Shortening Cycle Exercise
2019
Muscle architecture is an important component of muscle function, and recent studies have shown changes in muscle architecture with fatigue. The stretch-shortening cycle is a natural way to study human locomotion, but little is known about how muscle architecture is affected by this type of exercise. This study investigated potential changes in medial gastrocnemius (MG) muscle architecture after exhaustive stretch-shortening cycle exercise. Male athletes (n = 10) performed maximal voluntary contractions (MVC) and maximal drop jump (DJ) tests before and after an exercise task consisting of 100 maximal DJs followed by successive rebound jumping to 70% of the initial maximal height. The exerci…
Muscle‐tendon morphology and function following long‐term exposure to repeated and strenuous mechanical loading
2020
We mapped structural and functional characteristics of muscle‐tendon units in a population exposed to very long‐term routine overloading. Twenty‐eight military academy cadets (age: 21.00 ± 1.1 yrs; height: 176.1 ± 4.8 cm; mass: 73.8 ± 7.0 kg) exposed for over 24 months to repetitive overloading were profiled via ultrasonography with a senior subgroup of them (n = 11; age = 21.4 ± 1.0 yrs; height = 176.5 ± 4.8 cm; mass = 71.4 ± 6.6 kg) also tested while walking and marching on a treadmill. A group of eleven ethnicity‐ and aged‐matched civilians (age = 21.6 ± 0.7 yrs; height = 176.8 ± 4.3 cm; mass = 74.6 ± 5.6 kg) was also profiled and tested. Cadets and civilians exhibited similar morphology…
Scicli: conservazione, trasformazione e valorizzazione del "capitale territoriale"
2013
La ricerca che presentiamo deriva da un rapporto virtuoso tra un ente locale di tradizioni illustri, il Comune di Scicli, in provincia di Ragusa, e una struttura di ricerca dell’Università di Palermo – il Centro Interdipartimentale di ricerca sui centri storici (C.I.R.CE.S.). i . Il territorio comunale di Scicli è caratterizzato da un paesaggio di grande fascino in cui si alternano le fenditure scoscese delle “cave” e i costoni collinari che le disegnano. I fianchi delle colline a volte presentano configurazioni prevalentemente naturalistiche, costituite da bianchi paesaggi di roccia punteggiati dagli ingressi alle abitazioni in grotta e da macchie di vegetazione rupestre, a volte si presen…
The Ipsilateral Interhemispheric Transprecuneal Approach to the Atrium: Technical Considerations and Clinical Outcome on a Series of 7 Patients
2022
Surgical removal of tumors of the atrium is challenging due to their deep location, vascularization, and to their complex three-dimensional relationships with the highly functional white matter fibers of the region. To assess the feasibility and the effectiveness of the ipsilateral interhemispheric transprecuneus approach (IITA) for tumors involving the atrium and the posterior third of the temporal horn, a retrospective chart review of all patients who had undergone a surgical treatment for intraventricular tumors between January 2008 and January 2017 was performed, and the step-by-step approach is described. Ten patients affected by lesions of the atrium of the lateral ventricle underwent…
Tensor tympani muscle: strange chewing muscle
2007
This work seeks to alert medical and odontological staff to understanding and using interdisciplinary handling for detecting different pathologies’ common otic symptoms. It offers better tools for this shared symptomatology during therapy’s conservative phase. Tensor tympani muscle physiology and function in the middle ear have been veiled, even when their dysfunction and anatomical relationships may explain a group of confused otic symptoms during conventional clinical evaluation. Middle ear muscles share a common embryological and functional origin with chewing and facial muscles. This article emphasizes that these muscles share a functional neurological and anatomical dimension with the …
La SCIC : une structure originale pour une agriculture innovante
2018
International audience; Largement ignorée du milieu agricole, la SCIC est en plein développement pour structurer des projets collectifs à l'échelle territoriale. Cette société, à la forme commerciale, redéfinit les termes du pacte coopératif sur la base d'un sociétariat ouvert et pluriel pouvant correspondre aux nouvelles formes d'agriculture.
Il regime di mantenimento potenzia l’efficacia della chemioprofilassi endovescicale precoce e induzione settimanale nei confronti delle recidive degl…
2008
SCOPO DEL LAVORO: Malgrado l’efficacia della chemioterapia endovescicale eseguita precocemente dopo la resezione endoscopica di uroteliomi vescicali NMI sia stata confermata da numerosi studi multicentrici, ancora dubbio rimane il ruolo di un ulteriore schema terapeutico di mantenimento nel potenziarne l’efficacia. Ciò rimane ancora più incerto se alla singola instillazione segue un ciclo di instillazioni settimanali. Scopo dello studio è stato valutare l’utilità di uno schema di mantenimento mensile per un anno rispetto alla sola induzione settimanale per 6 settimane in pazienti sottoposti a TUR e chemioprofilassi precoce con epirubicina. MATERIALI E METODI: Sono stati randomizzati 577 paz…
LE VESCICOLE EXTRACELLULARI VEGETALI PER LO SVILUPPO DI NUOVI NUTRACEUTICI: STUDIO PRE-CLINICO E CLINICO DELLE PROPRIETÀ BIOLOGICHE DELLE VESCICOLE I…
2021
Razionale dello studio: Le vescicole extracellulari (EVs) sono strutture lipoproteiche rilasciate dalle cellule animali e vegetali, che veicolano sostanze bioattive tra cui lipidi, proteine, acidi nucleici e altri metaboliti, rendendole più stabili e biodisponibili. EVs isolate da semi, foglie e frutti di svariate specie vegetali presentano attività anti-tumorale, anti-infiammatoria ed anti-ossidante. Metodi e Risultati: Il nostro gruppo di ricerca si occupa da anni della caratterizzazione strutturale e funzionale delle EVs da succo di limone (LEVs). Le LEVs esercitano effetti antinfiammatori sia in vitro, su linee di macrofagi murini, che ex vivo, su linfociti T, attraverso l’inibizione de…
