Acciones Estratégicas para reducir los efectos de las Presiones Ambientales que influyen en el redimiento deportivo de Judocas (Original)

Recent data has shown that even in Olympic Games the athlete can lose a medal, a positive result due to the effects exerted by environmental pressures. The objective of this research is to propose a group of strategic actions to diminish the effects of environmental pressures in a judo team in Pinar del Río, Cuba. In order to carry out this study, a documentary review, a survey to athletes and an interview to Judo coaches were applied. It was demonstrated that all the pressures proposed in the study have a relative incidence in the state of opinion of the athletes, but it is the public pressure that most concerns the athletes. As a product of contribution to the solution of the scientific problem, a group of strategic actions is proposed that are directed to treat the pressures that most affect the athletes under study and also to foresee some consequences that could be caused by a deficient treatment of other environmental pressures.En datos recientes se ha demostrado que hasta en juegos olímpicos el atleta puede perder una medalla, un resultado positivo debido a los efectos que ejercen las presiones ambientales.

Factors associated with perception and expectations to work in the area of primary health care at five facilities of the first level care in Lima, Peru

Aim: To identify the frequency of perception and expectations to work in the area of primary health care(PHC) as well as theirassociated factors with personnel at five health facilities. Method: Cross-sectional study on five health facilities of PHC. Perception and expectations to work in PHC were measured, and their association with social-work variables was investigated. Simple and multiple regression analysis was performed to estimate prevalence ratios (PR), using the Poisson family, robust variance and having a health facility as a cluster. Results: Out of 94 participants, 64.9% did not have an adequate perceptionabout working in the area of PHC. The 60.6% had an expectation to work in PHC 10 years from now. A positive association was found between female gender and perception about working in the area of PHC (PR = 3.24). There was a negative association between being divorced and/or widowed and the expectation to work in PHC (PR: 0.51). Conclusions: Perception about working in PHC is low, but more than half of the sample expect to work in PHC10 years from now. Being a woman increases the prevalence job perception in PHC. Working time over 5 years was positively associated with having expectations to work in PHC. On the contrary, divorced/widowed marital status was negatively associated

Activation of the Wnt/β-Catenin Signaling Pathway by Mechanical Ventilation Is Associated with Ventilator-Induced Pulmonary Fibrosis in Healthy Lungs

BACKGROUND: Mechanical ventilation (MV) with high tidal volumes (V(T)) can cause or aggravate lung damage, so-called ventilator induced lung injury (VILI). The relationship between specific mechanical events in the lung and the cellular responses that result in VILI remains incomplete. Since activation of Wnt/β-catenin signaling has been suggested to be central to mechanisms of lung healing and fibrosis, we hypothesized that the Wnt/β-catenin signaling plays a role during VILI. METHODOLOGY/PRINCIPAL FINDINGS: Prospective, randomized, controlled animal study using adult, healthy, male Sprague-Dawley rats. Animals (n = 6/group) were randomized to spontaneous breathing or two strategies of MV for 4 hours: low tidal volume (V(T)) (6 mL/kg) or high V(T) (20 mL/kg). Histological evaluation of lung tissue, measurements of WNT5A, total β-catenin, non-phospho (Ser33/37/Thr41) β-catenin, matrix metalloproteinase-7 (MMP-7), cyclin D1, vascular endothelial growth factor (VEGF), and axis inhibition protein 2 (AXIN2) protein levels by Western blot, and WNT5A, non-phospho (Ser33/37/Thr41) β-catenin, MMP-7, and AXIN2 immunohistochemical localization in the lungs were analyzed. High-V(T) MV caused lung inflammation and perivascular edema with cellular infiltrates and collagen deposition. Protein levels of WNT5A, non-phospho (Ser33/37/Thr41) β-catenin, MMP-7, cyclin D1, VEGF, and AXIN2 in the lungs were increased in all ventilated animals although high-V(T) MV was associated with significantly higher levels of WNT5A, non-phospho (Ser33/37/Thr41) β-catenin, MMP-7, cyclin D1, VEGF, and AXIN2 levels. CONCLUSIONS/SIGNIFICANCE: Our findings demonstrate that the Wnt/β-catenin signaling pathway is modulated very early by MV in lungs without preexistent lung disease, suggesting that activation of this pathway could play an important role in both VILI and lung repair. Modulation of this pathway might represent a therapeutic option for prevention and/or management of VILI

Soluble platelet-endothelial cell adhesion molecule-1, a biomarker of ventilator-induced lung injury

Introduction: Endothelial cell injury is an important component of acute lung injury. Platelet-endothelial cell adhesion molecule-1 (PECAM1) is a transmembrane protein that connects endothelial cells to one another and can be detected as a soluble, truncated protein (sPECAM1) in serum. We hypothesized that injurious mechanical ventilation (MV) leads to shedding of PECAM1 from lung endothelial cells resulting in increasing sPECAM1 levels in the systemic circulation. Methods: We studied 36 Sprague–Dawley rats in two prospective, randomized, controlled studies (healthy and septic) using established animal models of ventilator-induced lung injury. Animals (n = 6 in each group) were randomized to spontaneous breathing or two MV strategies: low tidal volume (VT) (6 ml/kg) and high-VT (20 ml/kg) on 2 cmH2O of positive end-expiratory pressure (PEEP). In low-VT septic animals, 10 cmH2O of PEEP was applied. We performed pulmonary histological and physiological evaluation and measured lung PECAM1 protein content and serum sPECAM1 levels after four hours ventilation period. Results: High-VT MV caused severe lung injury in healthy and septic animals, and decreased lung PECAM1 protein content (P < 0.001). Animals on high-VT had a four- to six-fold increase of mean sPECAM1 serum levels than the unventilated counterpart (35.4 ± 10.4 versus 5.6 ± 1.7 ng/ml in healthy rats; 156.8 ± 47.6 versus 35.6 ± 12.6 ng/ml in septic rats) (P < 0.0001). Low-VT MV prevented these changes. Levels of sPECAM1 in healthy animals on high-VT MV paralleled the sPECAM1 levels of non-ventilated septic animals. Conclusions: Our findings suggest that circulating sPECAM1 may represent a promising biomarker for the detection and monitoring of ventilator-induced lung injury

La Educación Superior en Cuba: Un espacio de inclusión mediante las políticas públicas

La Educación Superior forma parte de las conquistas sociales que ha mantenido durante más de 50 años la revolución cubana. Constituye una de las obras más humanas y solidarias que se haya desarrollado en el mundo. Su inversión es importante para acometer el desarrollo económico-social de la nación, la cual se encuentra en el proceso de construcción socialista y, en las condiciones actuales, rediseña su modelo económico social. Desde la Economía Política como ciencia, es importante percibir a la Educación Superior, como una forma de distribución social. Carlos Marx en su estudio acerca de la reproducción, y los destinos de la riqueza creada a escala social, tuvo en cuenta que se instrumentaría, independientemente del aporte de cada cual, a la sociedad, sino que formaba parte según, el, de la satisfacción de necesidades colectivas. Sin embargo, la Educación Superior, dentro de los otros niveles educacionales, tiene sus peculiaridades y aunque en Cuba, todos por derecho que otorga la Constitución de la República podemos acceder a estos servicios, tiene un carácter elitista. Muchos factores inciden en ello forman parte de este análisis. Se trata entonces ante las nuevas condiciones de: Proponer vías que redunden en el perfeccionamiento de la Educación Superior, promuevan el acceso e inclusión mediante las políticas públicas. Se trata de lograr un mayor acceso a esta forma de enseñanza, sobre todo, tomando en cuenta que, en las condiciones actuales, la brecha en las desigualdades sociales, se amplían

Carbothermal reduction of mill scales formed on steel billets during continuous casting

AbstractA billet is a bar made from crude steel which surface contains scales which are rich in iron oxides. This study presents the carbothermal reduction of the scales formed in steel billets. The process included the reaction of the iron oxides contents with carbon (in ratio 5:1) and annealing in a tubular furnace under argon atmosphere. The occurred reactions are discussed using thermodynamic calculations and thermal analysis which indicate a three-stage reduction process Fe3O4 ➔ FeO ➔ Fe3C ➔α-Fe with intermediate reactions at the interval temperature 960 and 1300 °C. The X-ray diffraction confirms the reduction to α-Fe with minor presence of unreacted C, magnetite and wustite. Mössbauer spectroscopy analysis was performed at room temperature where a typical sextet corresponding to the dominant α-Fe is shown as well as wustite, magnetite and cementite to a lesser extent. The magnetization measurements confirm the ferromagnetic state corresponding to the α-Fe.</jats:p
