Genetic study in patients operated dentally and anesthetized with articaine-epinephrine

Aims: In this study we wanted to figure out if there was a correlation between OPRM1 N40D, TRPV1 I316M, TRPV1 I585V, NOS3 −786T>C and IL6 −174C>G polymorphisms and the response to locally applied articaine-epinephrine anesthetic. Methods: In this observational study, 114 oral cell samples of patients anesthetized with articaine-epinephrine (54 from men 60 from women), were collected from dental centers in Madrid (Spain). High molecular weight DNA was obtained from oral mucosa cells. The analysis of OPRM1 N40D (rs1799971), TRPV1 I316M (rs222747), TRPV1 I585V (rs8065080) and IL6 −174C>G polymorphism was performed through real-time PCR allelic discrimination using TaqMan probes. Polymorphism NOS3 −786T> C (rs2070744) was analyzed using RFLP-PCR. Results: The studied polymorphisms are involved neither in the response to the anesthetic, nor in the intensity of perceived dental pain. However, in a subset of female patients we found that TRPV1 I316M was associated with a delayed onset of anesthesia. Conclusions: There is no association among these polymorphisms and the time elapsed between the application of the anesthetic and the onset of its effect

Effect of stress and/or field annealing on the magnetic behavior of the „Co77Si13.5B9.5…90Fe7Nb3 amorphous alloy

Variations of coercive field, induced magnetic anisotropy, and saturation magnetostriction constant in sCo77Si13.5B9.5d90Fe7Nb3 amorphous ribbons submitted to stress and/or axial magnetic-field annealing are reported. The annealing was carried out by using the Joule-heating effect saverage temperature values of the sample corresponding to the intensity of the electrical current were 273, 378, 409, and 445 °Cd and the applied stress and axial magnetic field during the thermal treatments were 500 MPa and 750 A/m, respectively. As a result of these treatments, a uniaxial in-plane magnetic anisotropy, which affects drastically the soft magnetic character of the samples, was developed.Ministerio de Ciencia y Tecnología de España-MAT2001-0082-C04-0

Intervención farmacéutica en un caso de bradicardia asociada al uso de timolol por vía oftálmica

Una paciente habitual de nuestra farmacia comunitaria nos consulta acerca de un cuadro de astenia, debilidad y fatiga de varias semanas de evolución. Tras realizar el estado de situación inicial y estudiar el caso detectamos varios problemas relacionados con medicamentos, siendo una marcada bradicardia el más acuciante. El estudio en detalle de la farmacoterapia de la paciente revela que la fracción de timolol absorbida tras su instilación ocular, que emplea para tratar su hipertensión ocular, podría ser responsable de una acusada disminución de su frecuencia cardiaca. Dicha bradicardia puede ser especialmente significativa en personas de edad avanzada y en individuos que, como consecuencia del polimorfismo de la enzima responsable del metabolismo de timolol, expresan un determinado genotipo con menor capacidad de biotransformación. Intervenimos indicando a la paciente la conveniencia de que su médico valorase otras opciones para el tratamiento de la hipertensión ocular. Tras una visita a urgencias por el agravamiento de los síntomas, se constata la bradicardia severa y el betabloqueante es sustituido por un tratamiento alternativo (latanoprost). La intervención farmacéutica resulta en la retirada de timolol, la remisión de los síntomas y en la resolución de dos problemas relacionados con medicamentos

Noncommutative 6D Gauge Higgs Unification Models

The influence of higher dimensions in noncommutative field theories is considered. For this purpose, we analyze the bosonic sector of a recently proposed 6 dimensional SU(3) orbifold model for the electroweak interactions. The corresponding noncommutative theory is constructed by means of the Seiberg-Witten map in 6D. We find in the reduced bosonic interactions in 4D theory, couplings which are new with respect to other known 4D noncommutative formulations of the Standard Model using the Seiberg-Witten map. Phenomenological implications due to the noncommutativity of extra dimensions are explored. In particular, assuming that the commutative model leads to the standard model values, a bound -5.63 10^{-8} GeV^{-2}< theta <1.06 10^{-7}GeV^{-2} on the corresponding noncommutativity scale is derived from current experimental constraints on the S and T oblique parameters. This bound is used to predict a possibly significant impact of noncommutativity effects of extra dimensions on the rare Higgs boson decay H-> gamma gamma.Comment: Latex file, 11 pages, 1 figur

Actividades intersectoriales en la prevención de accidentes de tráfico

ResumenSe describen las líneas de trabajo priorizadas y algunos resultados obtenidos en la implantación del programa de prevención y reducción de lesiones por accidentes de tráfico en un área de salud. A partir de 1999 el Centro de Salud Pública priorizó la identificación y búsqueda de aliados en otros sectores (Asociación de policías locales y educación), la construcción de la capacidad de trabajo conjunta y la formación de un grupo intersectorial. Se llevaron a cabo actividades docentes y jornadas. Se formó una red de personas en 17 de un total de 39 ayuntamientos que participan con actividades en el grupo intersectorial. Un total de 10 de estos ayuntamientos participaron con actividades educativas y siete, además, exigieron al cumplimiento de la legislación.El grupo intersectorial potenció la visibilidad de sus actividades a través de los medios de comunicación local. Estas actividades no están dirigidas a reducir las lesiones por tráfico, sino a crear un marco de trabajo para la movilización de los sectores implicados. Se pretende potenciar más el compromiso entre los niveles políticos, técnicos y civiles incidiendo en valores sociales de respeto para una vida más saludable.AbstractWe describe priority issues and some of the results obtained from the implementation of the «Prevention and Reduction of Traffic Accident Injuries» program in a health area. Since 1999 the public health center has made a priority of identifying and recruiting partners from other sectors (the local police association and the local education authority), increasing its capacity for working together, and setting up an intersectorial working group. Teaching activities and meetings were held. A network of people was created from 17 of a total of 39 town halls that participate in activities supported by the intersectorial group. Ten are involved in educational activities and a further seven focus on ensuring compliance with the law. The intersectorial group promoted their visibility through the local media. These activities are not aimed at reducing injuries from road traffic accidents, but rather at creating an action framework through which all the sectors involved can be mobilized. The aim is to strengthen commitment among political, technical and civil sectors by focussing on social values of respect for a healthier life

Microalgal Biomass: A Biorefinery Approach

The biorefinery concept has been identified as the most promising way to create a biomass-based industry, which can be defined as the sustainable biomass processing to obtain energy biofuels and high-value products through processes and equipment for biomass. Microalgae can be used as an efficient and economically viable biorefinery feedstock; microalgae could be used in different areas such as human and animal nutrition, nutraceutical and therapeutic products, fertilizers, plastics, isoprenes and biofuels and also in the treatment of wastewaters and CO2 capture. Microalgae biomass can be used for biofuel production, such as bioelectricity, methane, biohydrogen, bioethanol and biodiesel. In this chapter, an overview of the factors that affect the production of the microalgal biomass yield and value-added by-products production is presented. Likewise, we present the results of the microalgal culture of Scenedesmus sp. SCX2 performed in semicontinuous culture (SCC), in 2000 raceway ponds employing Bold’s Basal Medium (BBM), under greenhouse conditions. Over the SCC, we monitored biomass concentration, lipid, protein, pigments and sugar production, light irradiance, culture and greenhouse temperature and nitrate concentration in the medium

Strength distribution of solar magnetic fields in photospheric quiet Sun regions

The magnetic topology of the solar photosphere in its quietest regions is hidden by the difficulties to disentangle magnetic flux through the resolution element from the field strength of unresolved structures. The observation of spectral lines with strong coupling with hyperfine structure, like the observed MnI line at 553.7 nm, allows such differentiation. The main aim is to analyse the distribution of field strengths in the network and intranetwork of the solar photosphere through inversion of the MnI line at 553.7 nm. An inversion code for the magnetic field using the Principal Component Analysis (PCA) has been developed. Statistical tests are run on the code to validate it. The code has to draw information from the small-amplitude spectral feature oppearing in the core of the Stokes V profile of the observed line for field strengths below a certain threshold, coinciding with lower limit of the Paschen-Back effect in the fine structure of the involved atomic levels. The inversion of the observed profiles, using the circular polarization (V) and the intensity (I), shows the presence of magnetic fields strengths in a range from 0 to 2 kG, with predominant weak strength values. Mixed regions with mean strength field values of 1130 and 435 Gauss are found associated with the network and intranetwork respectively. The MnI line at 553 nm probes the field strength distribution in the quiet sun and shows the predominance of weak, hectoGauss fields in the intranetwork, and strong, kiloGauss fields in the network. It also shows that both network and intranetwork are to be understood at our present spatial resolutions as field distributions of which we hint the mean properties.Comment: 10 pages, 6 figure

The informal social support for autonomy and dependence in pain inventory Spanish version

Social support plays a crucial role in the quality of life of people with chronic pain. The Informal Social Support for Autonomy and Dependence in Pain Inventory assesses two functions of received social support: the promotion of autonomy and the promotion of dependence. The aim of this cross-sectional study was to adapt this instrument for its use in the Spanish population. The sample comprised 256 individuals with chronic pain. Participants were recruited through two local associations of people with fibromyalgia, a physiotherapy unit and a hospital pain unit. The data were collected in Spain between October 2018 and January 2020. The structure of the questionnaire was analysed using confirmatory factor analysis, average variance extracted, composite reliability and internal consistency indexes, and inter-correlations between the scales. The criterion-related validity of the instrument was analysed by investigating its relationship with pain intensity, positive and negative affect, daily functioning, activity impairment, wellbeing and satisfaction with life. The structure with the best fit had four related factors: emotional social support for the promotion of autonomy; instrumental social support for the promotion of autonomy; emotional social support for the promotion of dependence and instrumental social support for the promotion of dependence. The scales showed adequate internal consistency. An association was found between higher levels of instrumental social support for the promotion of dependence and higher levels of pain-related disability and decreased daily functioning. An association was also found between the promotion of autonomy and increased satisfaction with life. The Spanish version of the inventory shows appropriate psychometric properties. In the setting of disability prevention, this instrument is useful in assessing the support relationships between people with chronic pain and their relatives.info:eu-repo/semantics/publishedVersio
