La organización y la gestión en los servicios sociales: el trabajador social en la organización y gestión de los servicios sociales
2010
En este artículo se pretende fomentar la reflexión de las y los trabajadores sociales en temas que no han sido considerados prioritarios entre las funciones a desarrollar desde el trabajo social y que sin embargo son elementos de primera necesidad si queremos hacer perdurar el sistema de servicios sociales, en el que una parte importante de la profesión desarrolla su actividad. Dotar a las unidades, departamentos, servicios, áreas en las que se trabaja de una estructura de organización y gestión que favorezca la consolidación del sistema, poner en valor la gestión del conocimiento, abordar el tema de introducir parámetros de calidad en los servicios que prestamos, establecer procesos y defi…
Cannabinoid type 1 receptor modulates intestinal propulsion by an attenuation of intestinal motor responses within the myenteric part of the peristal…
2007
Cannabinoid-1 (CB1) receptor activation affects gastrointestinal propulsion in vivo. It was our aim to further characterize the involved myenteric mechanisms in vivo and in vitro. In CB1(-/-) mice and wild-type littermates we performed in vivo transit experiments by charcoal feeding and in vitro electrophysiological recordings in mouse small intestinal smooth muscle. Ascending neuronal contraction (ANC) following electrical field stimulation was studied in rat ileum in a partitioned organ bath separating the aboral stimulation site from the oral recording site. The knockout animals displayed an accelerated upper gastrointestinal transit compared to control animals. The CB1 receptor antagoni…
Flexibility in otherwise consistent non-breeding movements of a long-distance migratory seabird, the long-tailed skua
2017
Quantifying within- and between-individual variation in animal migration strategies is a first step towards our understanding of the ability of migrants to adjust to changes in the en - vironment. We studied consistency (or, conversely, flexibility) in movement patterns at large (>1000 km) to meso-scales (100−1000 km) during the non-breeding season of the long-tailed skua Stercorarius longicaudus, a long-distance migratory Arctic seabird, using light-based geolocation. We obtained 97 annual tracks of 38 individuals and quantified similarity between routes. Overall, tracks of the same individual were generally within about 200 to 300 km of their previous year’s route, and more similar than t…
Basalt Fibre Composite with Carbon Nanomodified Epoxy Matrix under Hydrothermal Ageing
2021
This work aimed to investigate the effect of hybrid carbon nanofillers (e.g., carbon nanotubes/carbon nanofibers in the ratio 1:1 by mass) over the electrical and flexural properties for an epoxy matrix and corresponding basalt fibre reinforcing composite (BFRC) subjected to full-year seasonal water absorption. Hydrothermal ageing was performed by full immersion of the tested materials into distilled water according to the following model conditions (seasons). The mechanical properties were measured in three-point bending mode before environmental ageing and after each season. Upon environmental ageing, the relative change of flexural strength and elastic modulus of the epoxy and NC was wit…
Hydrothermal Aging of an Epoxy Resin Filled with Carbon Nanofillers
2020
The effects of temperature and moisture on flexural and thermomechanical properties of neat and filled epoxy with both multiwall carbon nanotubes (CNT), carbon nanofibers (CNF), and their hybrid components were investigated. Two regimes of environmental aging were applied: Water absorption at 70 °
Significance of passively induced stretch reflexes on achilles tendon force enhancement
1998
An in vivo buckle transducer technique was applied to study the reflex contribution to ATF enhancement during passive dorsiflexion stretches. Single stretches led to a linear ATF increase in the absence of an EMG reflex response, whereas clear ATF enhancement over the passive component occurred 13-15 ms after the onset of EMG responses. To quantify the reflexly induced increase in ATF, the stretched position was maintained. The mean reflex effect was two to four times greater than the passive stretch effect.
P1319 Speckle tracking echocardiography in patients with acute coronary syndrome: the added value
2020
Abstract Background Speckle tracking echocardiography with assessment of left ventricular global longitudinal strain (GLS) allows to identify early signs of cardiac dysfunction. The superiority of GLS in the prediction of all-cause mortality in the general population compared with LVEF is well known; in addiction GLS improves risk stratification and recognize early left ventricular dysfunction in several clinical setting. Purpose the aim of this study was to assess the diagnostic and prognostic role of global and segmental strain in the early identification of cardiac dysfunction in patients with myocardial infarction without persistent ST segment elevation (NSTEMI) and without obvious wall…
Evidence of a contralateral motor influence on reciprocal inhibition in man
1992
The role of contralateral movement on both H reflex and reciprocal inhibition was studied. In normal men H reflex was induced by median nerve stimulation. Reciprocal inhibition was achieved through stimulation of the antagonist radial nerve. On this basis the effects of contralateral arm movement were analized. Furthermore the putative influence of exteroceptive origin was also verified by means of digit stimulation. Results showed that contralateral arm movement did not affect H reflex amplitude; on the contrary, it was able to enhance reciprocal inhibition induced by extensors on flexors. Study of cutaneous afferents demonstrated that contralateral digit stimulation failed to elicit modif…
Anatomical correlates of ocular motor deficits in cerebellar lesions
2009
Humans are able to stabilize the images of moving targets on the retina by means of smooth pursuit eye movements. After the pontine level, all smooth pursuit pathways pass through the cerebellum. Previous animal studies gave evidence that two specific lesion sites within the cerebellum cause smooth pursuit disorders: those of the flocculus/paraflocculus and the vermis including lobule VI, VII, the uvula and the deep cerebellar nuclei. To date, there have been only a few lesion studies in patients with smooth pursuit disorders that do not allow direct comparison with a control group. In the present study, new lesion mapping techniques determined which cerebellar structures were involved in p…
Local anaesthetic sympathetic blockade for complex regional pain syndrome
2016
This is the peer reviewed version of the following article: The Cochrane database of systematic reviews, which has been published in final form at https://doi.org/10.1002/14651858.CD004598.pub4. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving. Background: This review is an update of a previously published review in the Cochrane Database of Systematic Reviews, 2005, Issue 4 (and last updated in the Cochrane Database of Systematic Reviews, 2013 issue 8), on local anaesthetic blockade (LASB) of the sympathetic chain to treat people with complex regional pain syndrome (CRPS). Objectives: To assess the efficacy of LASB for the…
