Alteraciones de la prueba ergométrica en pacientes con fibromialgia Alterations of the ergometric test in patients with fibromyalgia
Ana del Carmen Argüelles Zayas,Adalberto Infante Amorós,Marta M. Rivero Varona,Rosa María Flores Sánchez
Revista Cubana de Medicina , 2004,
Abstract: La fibromialgia es uno de los síndromes reumáticos más comunes, caracterizado por dolores musculoesqueléticos y puntos dolorosos sin existir sinovitis ni miositis. Se estudiaron 20 pacientes con diagnóstico de fibromialgia para conocer, mediante la prueba ergométrica, las alteraciones del sistema nervioso autónomo. Se observó, en el grupo control, un incremento normal de la frecuencia al adoptar el ortostatismo lo cual refleja activación del sistema simpático, mientras que en las pacientes con fibromialgia no existió dicho reflejo. Se comprobó incremento adecuado de la tensión arterial en el 87 % de las pacientes con fibromialgia, infradesnivel del ST mayor de 1 mm en el 20 % de las pacientes, ausencia de arritmia y síntomas de cardiopatía en todas las pacientes y disminución de la capacidad física en 4.Se concluyó que las pacientes con fibromialgia presentan una disfunción del sistema nervioso autónomo. Fibromyalgia is one of the commonest rheumatic symptoms, characterized by musculoskeletal pain and painful points with neither synovitis nor myositis. 20 patients with diagnosis of fibromyalgia were studied to know the alterations of the autonomous nervous system by the ergometric test. In the control group, it was observed a normal increase of frequency on adopting orthostatism, which reflects the activation of the sympathetic system. This reflex did not exist among the patients with fibromyalgia. An adequate rise of the arterial pressure in 87 % of the patients with fibromyalgia, an infraunevenness of the ST over 1 mm in 20 % of the patients, an absence of arrhytmia and symptoms of heart disease in all patients, and a reduction of physical capacity in 4, were proved. It was concluded that patients with fibromyalgia present a dysfunction of the autonomous nervous system.

Abstract: a longitudinal study to determine the presence of intestinal parasites in canine faeces and their relationship with seasonal weather conditions during a year was carried out. 481 fecal canine deposits were collected from 13 public parks in two cities of chubut province, patagonia argentina. stools were analyzed by means of telemann and willis methods. weather conditions were daily registered from local stations. the frequency of positive canine faeces to intestinal parasites was found between 34,9% and 51,2% over the studied period and was season independent (p > 0.05). a predominance of helminths over protozoa was detected in all seasons. frequency of entamoeba spp. and nematoda was seasonal dependent (p < 0.05). the finding of toxocara canis eggs varied from 12,7% in winter to 20,9% in spring. pathogens to humans such as t. canis, taenia spp., uncinaria spp. and entamoeba spp. were found. spirocerca spp. and capillaria spp. have been reported for the first time for this region.
La filosofía del sujeto y la sociología del conocimiento en las teorías de Ju rgen Habermas y Niklas Luhmann
Sánchez Flores, Mónica Judith
CONfines de relaciones internacionales y ciencia política , 2007,
Abstract: In this article I show that, in spite of essential differences between Habermas and Luhmann with respect to the philosophy of the subject, they both depend on the modern idea of the individual self to pose their theories of meaning (Habermas 1989 and 1990, Luhmann 1998). Habermas and Luhmann belong to divergent theoretical schools (critical and functionalist respectively) and yet they both use essential lessons about language from the German “sciences of the spirit” (Geisteswissenschaften); the phenomenological perspective and the sociology of knowledge. Even though their positions on the value of the modern individual self are opposed, the latter is an essential element in the theoretical perspectives of both sociologists: Habermas describes the individual subject as a linguistically competent, rational, and critical entity; while Luhmann rejects this anthropocentric conception outright and contemplates society as a set of systems oriented towards their own functionality. Luhmann produces a very useful sociological perspective, but rhetorically rejects the substantive aspect of the philosophy of the subject without recognizing that his perspective depends on the consciousness of the subject that he rejects at the same time. In the light of this dilemma I argue that it is necessary to remember essential lessons from Max Weber’s methodology of the social sciences.
Causality and Conjugate Points in General Plane Waves
J. L. Flores,M. Sánchez
Physics , 2002,
Abstract: Let $M = M_0 \times \R^2$ be a pp--wave type spacetime endowed with the metric $<\cdot,\cdot>_z = <\cdot,\cdot>_x + 2 du dv + H(x,u) du^2$, where $(M_0, <\cdot,\cdot>_x) $ is any Riemannian manifold and $H(x,u)$ an arbitrary function. We show that the behaviour of $H(x,u)$ at spatial infinity determines the causality of $M$, say: (a) if $-H(x,u)$ behaves subquadratically (i.e, essentially $-H(x,u) \leq R_1(u) |x|^{2-\epsilon} $ for some $\epsilon >0$ and large distance $|x|$ to a fixed point) and the spatial part $(M_0, <\cdot,\cdot>_x) $ is complete, then the spacetime $M$ is globally hyperbolic, (b) if $-H(x,u)$ grows at most quadratically (i.e, $-H(x,u) \leq R_1(u) |x|^{2}$ for large $|x|$) then it is strongly causal and (c) $M$ is always causal, but there are non-distinguishing examples (and thus, non-strongly causal), even when $-H(x,u) \leq R_1(u) |x|^{2+\epsilon} $, for small $\epsilon >0$. Therefore, the classical model $M_0 = \R^2$, $H(x,u) = \sum_{i,j} h_{ij}(u) x_i x_j (\not\equiv 0)$, which is known to be strongly causal but not globally hyperbolic, lies in the critical quadratic situation with complete $M_0$. This must be taken into account for realistic applications. In fact, we argue that $-H$ will be subquadratic (and the spacetime globally hyperbolic) if $M$ is asymptotically flat. The relation of these results with the notion of astigmatic conjugacy and the existence of conjugate points is also discussed.
The Health of Paid Caregivers: A Cross-Sectional Study in Spanish Population  [PDF]
Isabel Cuéllar-Flores, Rosa M. Limi?ana-Gras, M. Pilar Sánchez-López
Psychology (PSYCH) , 2013, DOI: 10.4236/psych.2013.46A1008
Abstract:

In countries with a welfare system, such as Spain, paid caregiving is an important profession and investigating the health of people who care for the health of others is becoming an issue of increasing interest. This paper reports on a study assessing the health of people who care for the health of others. It investigates whether caregiving jobs carry with them a higher risk of psychological and physical health problems than other unrelated occupations, and it examines whether risk profiles differ by sex and educational level. A descriptive correlational approach and a cross-sectional design were used. The sample included 330 participants. Half of the participants worked as caregivers, and the other half worked in professions unrelated to caregiving services. The results indicate that paid caregivers have poorer health than their matched counterparts. The variable of caregiving explains this difference better than sex or educational level and professional category.

Mineralogical and morphological changes of fly ashes with leaching phenomenon
Marta, J.,Sánchez Rojas, M. I.,Frías, M.
Materiales de Construccion , 1999,
Abstract: In this study, three Fly Ashes (FA) from Spanish Power Plants with CaO contents between 2-30% in weight were examined. They were leached using a variation on EPA-EP leaching test, checking the influence of the leaching process on FA. Leaches were analyzed by ICP. XRD and SEM-EDX technique were used to analyze the leached FA. The study carried out was mainly centered in following the evolution of the most soluble elements and the formation of new secondary crystalline phases. The relationship between dissolution pH and the percentage of the extracted element was also confirmed. La investigación se realiza en tres cenizas volantes espa olas con contenidos de CaO entre 2-30% en peso. Para observar el proceso de lixiviación en estos subproductos industriales se lleva a cabo un ensayo similar al descrito por la EPA-EP. Las aguas lixiviadas se analizan por la técnica ICP, mientras que los residuos se caracterizan por difracción de rayos X y SEM-EDX. El estudio se centra en el seguimiento de los elementos más solubles, según la metodología aplicada, y en la formación de nuevas fases cristalinas secundarias. Además, se confirma la relación existente entre el pH de la disolución y el porcentaje de elemento extraído.

Abstract:

Background: Aloe vera has been used by many civilizations throughout history due to the numerous properties attributed. Gastro oesophageal reflux disease is a common disorder with consequences for the patient’s health related quality of life. Aims: The purpose of this study was to assess the benefits of the Aloe vera in 80 patients with gastro oesophageal reflux. Methods: This is probably the first randomised and double-blind trail ever performed on this subject. The study included eight weeks of treatment with milk enriched with Aloe vera or placebo. Data of diet (frequency questionnaire), symptoms (gastrointestinal symptom rating scale) and quality of life (quality of life in reflux and disease) were obtained. Results: So far, there has been hardly any proof that Aloe vera decreases symptoms of reflux disease; on the contrary, a lower percentage of remission of pain is observed among the Aloe vera group. As long as its effectiveness has not been proven properly, the use of Aloe vera in reflux disease cannot be recommend. Conclusion: Aloe vera does not have a beneficial effect on reflux disease under the study conditions.

Enzimas generadoras de especies reactivas del oxígeno: mieloperoxidasa
García Morales,Onel H; Pereira Roche,Nayade; Flores Sánchez,Rosa M;
Revista Cubana de Investigaciones Biom??dicas , 1998,
Abstract: organism′s defence is mediated by cells of the so-called reticuloendothelial system, of which, nautrophils polymorphonuclear, are the first line of nonspecific defense. myeloperoxidase is the more abundant protein in neutrophils, and is the sole peroxidase catalising hydrogen peroxide and chloride donversion to hypochlorous acid. this es a powerful oxidative agent leading to defense mechanism against infectious agents; however, is able to act on host cells in case of uncontrollable or excessive activation, and in the humoral factors inactivation. in view of the ample spectrum of reactivity, hypochlorous acid is a mediator of tissue damage in many inflammatory process. authors present some physico-chemical features, mechanism of action, biosynthesis, and relation of myeloperoxidase with different pathologic process.

Abstract: La defensa del organismo está mediada por las células del llamado sistema retículo endotelial, de las cuales los polimorfonucleares neutrófilos constituyen la primera línea de defensa inespecífica. La mieloperoxidasa es la proteína más abundante en los neutrófilos y es la única peroxidasa que cataliza la conversión del peróxido de hidrógeno y cloruro a ácido hipocloroso. Este es un potente agente oxidante que contribuye al mecanismo de defensa contra los agentes infecciosos; sin embargo, puede ser capaz de actuar sobre las células del hospedero en caso de activación incontrolable o excesiva e inactivar factores humorales. Dado el amplio espectro de reactividad, el ácido hipocloroso es un mediador de da o hístico en numerosos procesos inflamatorios. Se presentan algunas características físico-químicas, el mecanismo de reacción, la biosíntesis y la relación de la enzima mieloperoxidasa con diferentes procesos patológicos.
