Distribución longitudinal de Hydraenidae y Elmidae (Coleoptera) en la cuenca del río Órbigo (León, España)

Making use of the distance to the source, an anylisis of the longitudinal distribution of 32 taxa of Hydraenidae and Elmidae frorn lotic environments is carried out. By means of a statistical method, the indicator species in relation to this factor have been identified. Three groups of taxa have been distinguished according to their distribution: species of upper reaches, those of lower reaches and those widely distributed. Both families are compared in terms of their longitudinal zonation; Hydraenidae have been found to be more closely related to upper reaches, whereas Elmidae show, as a whole, a wider ecological amplitude and a preference to areas near the confluence.Tomando como parámetro estudiado la distancia al nacimiento, se establece la zonación de los treinta y dos taxones de Hydraenidae y Elmidae recogidos en ambientes lóticos de la cuenca del Órbigo. Por medio de un conjunto de técnicas estadísticas se establecen cuáles de estos taxones pueden ser considerados como indicadores del factor analizado. Dentro de éstos se han distinguido, en base a su repartición, tres grupos de especies: de cabecera, de tramos inferiores y ampliamente distribuidas. Se compara la distribución de las dos familias, observándose que Hydraenidae, en lineas generales, queda relegada a tramos superiores, mientras que la familia Elmidae, en conjunto, manifiesta una mayor amplitud ecológica y cierta preferencia por zonas mis próximas a la desembocadura

Electromyographic biofeedback training for reducing muscle pain and tension on masseter and temporal muscles: A pilot study

Due to the absence of agreement about an effective unified treatment for temporomandibular disorders, non-invasive therapies such as EMG-biofeedback generate a greater interest. Furthermore, most studies to the present show methodological deficiencies that must be solved in the future, which makes important to emphasize this line of studies. Fourteen patients were selected for this case series study, and replied to a questionnaire concerning awareness of bruxism, painful muscles, and muscle tension. They also practiced an intraoral exploration (occlusal analysis and mandibular dynamics), and an extraoral exploration of the head and neck muscles and the temporomandibular joint. Before each session, patients responded to a questionnaire about the subjective perceived improvement. In each session, a period of three minutes of pre-biofeedback EMG activity of right masseter and temporal muscles was registered, then patients performed 30 iterations of visual EMG-biofeedback training and finally, a period of three minutes of post-EMG activity was also registered for those muscles. Patients performed four sessions. A decrease in painful symptoms was found for all patients since the first session. EMG activity decreases (p<0,05) in both muscles during the biofeedback training stage, in the four sessions. It is also observed a decrease (p<0,05) in EMG activity in the masseter muscle at the post-biofeedback stage, in the second and third sessions. There is likewise a decrease in EMG post-biofeedback activity of the temporal muscle (p<0,05) in sessions two, three, and four. EMG-biofeedback training produces a decrease in EMG activity in both masseter and temporal muscles during the session. This decrease persists during the post-biofeedback period since the second session. Also there is a decrease in painful symptoms for all patients

Estudio sobre la motivación del profesorado en un contexto urbano

The present study aims to determine the motivation of kinder garden, primary and secondary teachers in the city of Vigo. The sample consists of 392 teachers (111 men and 281 women) with an average age of 45.20 years and an average of 19.86 working years. The instrument tool used in the research was The Work Task Motivation Scale for Teachers (Fernet, Senecal, Guay, Marsh, and Dowson, 2008), based on the Self-Determination Theory. This 90 items scale was designed to measure five motivational constructs (intrinsic motivation, identified regulation, introjected regulation, external regulation and amotivation) among towards six of the work tasks of teachers (teaching, class preparation, evaluation of students, classroom management, administrative tasks and complementary tasks).Results show low scores on in a motivation demotivation in the 6 tasks set, which means that teachers do not have suffer a motivation lack of motivation. The tasks in which teachers are intrinsically motivated are teaching and class preparing. Otherwise, while low values are observed in introjected regulation when performing administrative tasks , complementary tasks or when evaluating students. This means that these three actions are performed, not because they are motivating in by themselves, but in order to avoid guilt or anxiety or to promote self-esteem.El presente estudio tiene como objetivo determinar la motivación del profesorado de educación infantil, primaria y secundaria de la ciudad de Vigo.

Las tareas en las que la motivación intrínseca es mayor son enseñar y preparar clases, mientras que observamos valores bajos en regulación introyectada a la hora de llevar a cabo tareas administrativas, tareas complementarias o al evaluar a los alumnos. Esto supone que estas tres acciones se llevan a cabo, no porque sean motivadoras en sí mismas, sino con el fin de evitar la sensación de culpa o ansiedad o para favorecer la autoestima

Mechanism of the photosensitizing action of a mixture humic acid-riboflavin in the degradation of water-contaminants

Kinetic and mechanistic aspects on the photooxidation of 3-hydroxypyridine (3-OHP) and phenol (PhOH), taken as model compounds for hydroxyaromatic water-contaminants, was studied. A mixture of the naturally occurring visible-light absorbers humic acid (HA) and vitamin B2 (riboflavin, Rf) was employed as a photosensitizing agent. The work was done in pH 7 aqueous solution, in the presence of 0.04 mM Rf and 50 μg/ml HA and employing photoirradiation wavelengths higher than 360 nm, a range where 3-OHP and PhOH are transparent. The mechanism involved in the photooxidation was mainly evaluated through oxygen consumption measurements. The mixture HA + Rf generates O2(1Δg) and O2-, the latter especially in the presence of electron donors such as the hydorxyaromatic compounds. The rates of oxygen consumption were taken as a measure of the overall oxidation rate of the contaminant model compounds. The photooxidation of 3-OHP at pH 7, sensitized by low Rf and HA concentrations, and standarized by comparison with the photooxidation rate of the known oxidizable target furfuryl alcohol, is an efficient process. PhOH is only degradable in the alkaline range of pH. A moderate decrease in the rate of oxygen consumption by 3-OHP upon Rf + HA sensitization was observed as compared to the simple addition of the oxygen uptake rates for 3-OHP upon individual Rf and HA sensitization. It is attributed to a catalytic decomposition of O2- by HA, which competes with 3-OHP by the oxidative species, inhibiting this oxygen-consumer channel, especially active in the presence of the pyridine derivative. Noticeable photofading of the sensitizers was detected when photolyzed in the absence of the contaminants, within typical irradiation times employed for the hydroxyaromatics degradation.Fil: Pajares, Adriana Mabel.

Factors Involved in the Functional Motor Recovery of Rats with Cortical Ablation after GH and Rehabilitation Treatment: Cortical Cell Proliferation and Nestin and Actin Expression in the Striatum and Thalamus

Previously we demonstrated, in rats, that treatment with growth hormone (GH) and rehabilitation, carried out immediately after a motor cortical ablation, significantly improved the motor affectation produced by the lesion and induced the re-expression of nestin in the contralateral motor cortex. Here we analyze cortical proliferation after ablation of the frontal motor cortex and investigate the re-expression of nestin in the contralateral motor cortex and the role of the striatum and thalamus in motor recovery. The rats were subjected to ablation of the frontal motor cortex in the dominant hemisphere or sham-operated and immediately treated with GH or the vehicle (V), for five days. At 1 dpi (days post-injury), all rats received daily injections (for four days) of bromodeoxyuridine and five rats were sacrificed at 5 dpi. The other 15 rats (n = 5/group) underwent rehabilitation and were sacrificed at 25 dpi. GH induced the greatest number of proliferating cells in the perilesional cortex. GH and rehabilitation produced the functional recovery of the motor lesion and increased the expression of nestin in the striatum. In the thalamic ventral nucleus ipsilateral to the lesion, cells positive for nestin and actin were detected, but this was independent on GH. Our data suggest that GH-induced striatal nestin is involved in motor recoveryThis research was funded by Foundation Foltra (Teo, Spain), grant number 2018-8S

Overexpression of kynurenic acid and 3-hydroxyanthranilic acid after rat traumatic brain injury

[EN]Using an immunohistochemical technique, we have studied the distribution of kynuneric acid (KYNA) and 3-hydroxyanthranilic acid (3-HAA) in a rat brain injury model (trauma). The study was carried out inducing a cerebral ablation of the frontal motor cortex. Two mouse monoclonal specific antibodies previously developed by our group directed against KYNA and 3-HAA were used. In control animals (sham-operated), the expression of both KYNA and 3-HAA was not observed. In animals in which the ablation was performed, the highest number of immunoreactive cells containing KYNA or 3-HAA was observed in the region surrounding the lesion and the number of these cells decreased moving away from the lesion. KYNA and 3-HAA were also observed in the white matter (ipsilateral side) located close to the injured region and in some cells placed in the white matter of the contralateral side. The distribution of KYNA and 3-HAA perfectly matched with the peripheral injured regions. The results found were identical independently of the perfusion date of animals (17, 30 or 54 days after brain injury). For the first time, the presence of KYNA and 3-HAA has been described in a rat trauma model

Effectiveness of motivational interviewing to improve therapeutic adherence in patients over 65 years old with chronic diseases: A cluster randomized clinical trial in primary care.

Objective: To evaluate the effectiveness of motivational interviewing (MI) in improving medication adherence in older patients being treated by polypharmacy. Methods: Cluster randomized clinical trial in 16 primary care centers with 27 health care providers and 154 patients. Thirty-two health care providers were assigned to an experimental (EG) or control group (CG). Interventions: MI training program and review of patient treatments. Providers in the EG carried out MI, whereas those in the CG used an “advice approach”. Three follow-up visits were completed, at 15 days and at 3 and 6[0] months. Medication adherence in both groups was compared (p<0.05). Results: Patients recruited: 70/84 (EG/CG). Mean age: 76 years; female: 68.8%. The proportion of subjects changing to adherence was 7.6% higher in the EG (p<0.001). Therapeutic adherence was higher for patients in the EG (OR=2.84), women (OR=0.24) and those with high educational levels (OR=3.93). Conclusion: A face-to-face motivational approach in primary care helps elderly patients with chronic diseases who are being treated by polypharmacy to achieve an improved level of treatment adherence than traditional strategies of providing information and advice. Practice Implications: MI is a patient-centered approach that can be used to improve medication adherence in primary care.pre-print152 K

Trasplantes amigdalares embrionarios en ratas adultas con lesiones de la corteza motora: análisis molecular y electrofisiológico

Transplants of embryonic nervous tissue ameliorate motor deficits induced by motor cortex lesions in adult animals. Restoration of lost brain functions has been recently shown in grafts of homotopic cortical origin, to be associated with a functional integration of the transplant after development of reciprocal host-graft connections. Nevertheless little is known about physiological properties or gene expression profiles of cortical implants with functional restorative capacity but no cortical origin. In this study, we show molecular and electrophysiological evidence supporting the functional development and integration of heterotopic transplants of embryonic amygdalar tissue placed into pre-lesioned motor cortex of adult rats. Grafts were analyzed 3 months post-transplantation
