Análisis Biomecánico de la carrera en curva y línea recta: Efectos del radio sobre los impactos de aceleración
2023
Introducción: Correr en curva requiere de cambios biomecánicos comparado con correr en calle recta. Los atletas de velocidad se enfrentan a adaptaciones cinemáticas cuando corren en curva. Se generan fuerzas de forma asimétrica en extremidades inferiores, lo que conlleva a desarrollar asimetrías a nivel óseo-muscular. Objetivo: Determinar si existen diferencias en los impactos de aceleración en la extremidad inferior al correr en curva y calle recta. Material y Método: Ocho atletas, 5 hombres y 3 mujeres (edad 16,3 ± 1,7 años, masa 58,5 ± 11,4 kg, talla 172,6 ± 10,5 cm) especialistas en pruebas de velocidad 100, 200 y 400m ejecutaron dos series por calle de 60m a velocidad máxima en la call…
In vitro plant regeneration of caper (Capparis spinosa L.) from floral explants and genetic stability of regenerants
2011
A new technique to regenerate caper plants (Capparis spinosa L. subsp. rupestris) starting from flower explant is reported. In vitro plant regeneration was attempted using stigma, anthers and unfertilized ovules of unopened flowers collected in the field. Plant regeneration was achieved from unfertilized ovules on MS medium supplemented with 88 mM sucrose and 13 lM 6-benzyladenine (BA). New individuals obtained from unfertilized ovules were used as source material for micropropagation and multiple shoots were obtained on MS medium sup- plemented with the adeninic cytokinin BA and the auxin indole-3-butyric acid (IBA). Explants obtained in micro- propagation step were used for rooting step u…
Angiotensin II type-2 receptors and colonic dysmotility associated to experimental colitis in rats
2016
Angiotensin II (Ang II) is a newly discovered modulator of intestinal motility, mainly via activation of excitatory AT1 receptors (AT1R). We demonstrated that during gut inflammation there is a recruitment of inhibitory AT2 receptors (AT2R) which would counteract the AT1R-induced effects. Our objective was to explore the consequence of AT2R activation in the pathogenesis of experimental colitis. Colitis was induced in rats by intrarectal administration of 2,4-Dinitrobenzene sulfonic acid (DNBS). Colonic damage was assessed by macro- and microscopic scores, myeloperoxidase activity and inflammatory cytokine expression on day 6 after colitis induction. Colonic contractility was recorded in vi…
Role for D1-like and D2-like dopamine receptors in the modulation of intestinal motility in mice
2015
Objective: In the last years a plethora of studies addressed dopamine (DA) as a modulator within the enteric nervous system (ENS), controlling gastrointestinal (GI) functions via activation of D1- and D2-like receptors. However, the effective role and functional significance of DA in the ENS, and the contribution of its receptors, are still a matter of debate. Pathological alterations of dopaminergic system in the gut may be likely implicated in different motor GI disorders, including dyspepsia and gastroparesis. Thus, a detailed characterization of the enteric dopaminergic signalling is necessary. The aim of this study was to explore the role of DA in the GI tract, using as model the mouse…

I GESTI MOTORI NELLE SCOLIOSI MINORI
2008
Per scoliosi s'intende una deviazione laterale permanente della colonna vertebrale, che si accompagna ad alterazioni anatomiche delle vertebre e delle altre strutture di sostegno del tronco. La Scoliosis Research Society definisce la scoliosi come una curva (> 10 gradi Cobb) sul piano frontale che si manifesta con un'inclinazione laterale, che comporta l'allontanamento di un certo numero di vertebre dalla linea mediana; questa modificazione dà origine ad una curva laterale, caratterizzata da un apice, essendo la vertebra apice la più scostata dall’ asse mediano, e da vertebre neutre o vertebre limite, alle estremità della curva, dove le articolazioni intervertebrali ritornano verso la linea…
Risposte agli stress ambientali in CYSTOSEIRA (C. AGARDH): effetti della temperatura sul contenuto dei composti fenolici
2012
Phenolic compounds are secondary metabolites involved in different protection mechanisms as, for example, against grazers, epiphytes and UV radiation. Seasonal variations of phenolic content in C. amentacea were analysed and laboratory experiments, in which C. amentacea was exposed to an increase of temperature (258C and 308C), were performed. Total phenolic content (TPC) was determined colorimetrically with the Folin–Ciocalteu reagent. In C. amentacea, a seasonal pattern in TPC was observed, with a maximum value in winter-spring. C. amentacea responded significantly to the temperature treatments with a consistent decrease in TPC after 48 h.
