Highlights: • The combination of biomechanical analysis and open-access Kinovea software enables the study of musculoskeletal and articular wear of experimentally reproduced tasks. • The repeated use of the right arm during indirect percussion and abrasion in lithic production could increase the changes in bone robusticity of specific muscle atta...

Se hace una revisión de la evolución de los estudios de Matrona en Europa, desde la atención al parto basada en la transmisión oral entre generaciones y la tradición cultural, hasta la asistencia basada en los conocimientos científicos actuales. Esta profesión ha tropezado con numerosos obstáculos a lo largo de la historia por ser considerada en su...

La Biomecánica de la rodilla es un campo necesario para entender gran parte de la patología de esta articulación, y en este trabajo se hace una revisión exhaustiva de la misma.

Childhood obesity is nowadays a global epidemic. This illness sometimes comes with another associated problem, like Diabetes type II. In this paper we present a case of study about the results of the application of a gamified educational program. A 3-year longitudinal and prospective study was conducted a patient with obesity and diabetes. Differen...

During suspended training athletes usually take a close grip or an open one. Here we compare both of them through superficial EMG in different tasks.

World Health Organization (WHO) has declared obesity as an epidemic of the XXI century after reaching global proportions. In Spain, this disease is suffered by 62% of the population leading to the emergence of new health problems. Increasing numbers of childhood obesity in the world is a direct result of changes in the lifestyles of the population....

In this paper we have made the comparison of two different methods for calculating the fat component of body weight in athletes. One through a new mathematical formula, the CUN-BAE (Clínica Universitaria de Navarra-Body Adiposity Estimation), described by Gomez-Ambrosi et al in 2012, and another using dual X-ray absorptiometry or DXA, which is cons...

RESUMEN La Lucha Canaria (LC) ha sido recientemente reconocida como deporte por el Consejo Superior de Deportes, aunque su origen se pierde en el tiempo. Sin embargo, no hay ningún trabajo en la bibliografía científica que describa qué ocurre fisiológicamente durante la competición en esta modalidad de lucha, y éste es el objetivo del presente tra...

The aim of this article is to describe what happens from a physiological point of view in a Canarian Wrestling (CW) contest. The Spanish National Sports Council recognized Canarian Wrestling as a sport on June 1st, 2009, although its origin is not very well documented. No scientific article exists in the scientific literature to describe what happe...

Subcommissural organ (SCO) secretory activity of the goat (variations of Capra hircus, that live in arid conditions) was examined during the postnatal development, using specific antibodies against the Reissner's fibre (AFRU) and angiotensin II (AAGII). The SCO was strongly stained with the anti-glycoproteins that form the Reissner's fibre and ligh...

We studied the effects of spontaneous high blood pressure and the captopril treatment on the subfornical organ (SFO) of rats. The brains of control Wistar-Kyoto rats (WKY), WKY rats treated with captopril (WKY-T), spontaneously hypertensive rats (SHR) and SHR rats treated with captopril (SHR-T) were processed immunohistochemically using anti-angiot...

El OSC es una diferenciación del revestimiento ependimario que hace relieve en la parte más posterior del techo del tercer ventrículo, localizado caudal a la glándula pineal, bajo la comisura posterior y al inicio del acueducto de Silvio. La regulación del equilibrio hidrosalino corporal es una de las funciones con la que se le ha relacionado al OS...

Estudiamos cualitativa y cuantitativamente el área postrema (AP) de ratas machos, espontáneamente hipertensas (SHR) y normo tensas Wistar-Kyoto (WKY). También se registró la presión arterial así como el agua y la solución salina bebida. Las ratas SHR bebieron más solución salina que agua. El tamaño nuclear de las neuronas de la parte rostral de la...

Most types of wrestling classify competitors by weight. In Canarian wrestling the best performers are known as "puntales" (A, B and C), without taking their weight into account. Few morphological studies of Canarian wrestlers have been performed. This means that there is a lack of scientific information that could limit their performance. No Refere...

We studied immunohistochemically the posterior lobe of the hypophysis (PL) of 15-week-old spontaneously hypertensive rats (SHR) and of matched normotensive Wistar Kyoto rats (WKY), by using our own polyclonal antibody raised in mice against Angiotensin II (mouse-antiangiotensin II, MAAII). The blood pressure, water intake and volume of the PL were...

The present study analyses the effects of hypertension and/or its oral treatment with captopril (angiotensine-converting enzyme inhibitor) on the rat median eminence (ME) and the posterior lobe of the hypophysis (PL). After an immunohistochemical reaction using an antibody against arginine-vasopressin, we compared by densitometry the amount of vaso...

A three dimensional analysis was used to compare the technical execution of two techniques of two very similar types of struggle. One, from a Japanese Martial Art known as Judo, and the other from The Canary Islands, called Canarian Wrestling. We explored these techniques with the possibility of bring something new to a young sport from another old...

We have studied the morphometric changes of the neurons of the cingular area 24 and frontal area 6 of the mouse, produced by age and/or chronic alcohol intake. The parameters analyzed were nuclear area of these cortical neurons and cellular density (cell/neuropil coefficient). We detected a decrease in the number of neurons with age in practically...

The subcommissural organ (SCO) is a glandular circumventricular organ secreting glycoproteins into the cerebrospinal fluid. The SCO of 15-week-old spontaneously hypertensive rats (SHR) and of matched normotensive Wistar-Kyoto rats (WKY) was studied immunocytochemically by using an antibody against the glycoproteins secreted by the SCO. The blood pr...

The effects of Captopril (an angiotensin-converting enzyme inhibitor) on the median eminence (ME) of the male albino mouse have been examined using morphometric and immunohistochemical procedures. We measured the nuclear area of the ependymocytes of the ME and of the glial cells of the reticular external zone of the ME. We also determined the cell/...

The present study analyses the response of the paraventricular (PVN) and supraoptic (SPO) nuclei of the hypothalamus of the male mouse to chronic alcohol intake by immunohistochemical and morphometric methods. We relate the intensity of the reaction to A-V with the vasopressin content of the nucleus, as all the slides, from the control and experime...

We have analyzed the morphometric effects on the dorsal vagal complex (DVC) of the rat of alcohol exposure and/or hypoproteic diet intake during 8 weeks. In the area postrema (AP), alcohol treatment (combined with normal isoproteic or hypoproteic diet) caused a significant decrease in karyometric parameters. In the dorsal motor nucleus of the vagus...
