Abstract: Suicide is treated by society as a taboo subject despite it being the leading cause of unnatural death in Spain. The Tenerife Province is ranked 16th among the 52 Spanish provinces for its suicide rate. From 2007 till 2010, the rate increased from 2007 to 2008, then dropped in 2010. Slight rise occurred in suicide rates in 2010. This rate increased from 2007 to 2008, with a decrease of rate in 2010. Slight rise occurred in suicide rates in 2010. In 2013 the province saw 75 suicides per year. 90% - 98% of suicides are closely related to mental disease with the remaining 10% associated with different poor causes of the subject, according to bibliography. In this retrospective study, it has been found that the highest risk rests with men over 40 years of age in the central and southern part of the island. Among the forms of suicide reported, the most common is hanging followed by jumping from a height. It’s important to understand the reasons behind suicidal behavior from a psychosocial perspective, taking into account “unsafe” indicators and individual profiles. The lethal nature of a suicide attempt also depends on the form of suicide adopted and the possibility of a rescue. Specific protocols to prevent suicide should be promoted and discussed between health and social services.

Abstract: La vacuna antitifoídica vax-TyVi consiste en una preparación de polisacárido capsular Vi de Salmonella typhi, el cual es diluido en una solución buffer isotónica solución amortiguador, a laque se le a ade fenol como preservo. Cada dosis de 0,5 mL contiene 25 μg de polisacárido como sustancia activa. En nuestro país el esquema de vacunación contra la fiebre tifoidea con vax-TyVi se aplica a los alumnos de 9-10 a os (5to grado), una 2da dosis a la edad de 12-13 a os (8vo grado) y una 3ra dosis a la edad de 16-17 a os (11no grado). Además, es vacunado el personal de riesgo de Salud Pública y el personal que manipula alimentos. En el presente trabajose describe el ensayo de tolerancia local llevado a cabo con la vacuna vax-TyVi durante su fase de estudios preclínicos, actualmente utilizada en la vacunación contra la fiebre tifoidea en Cuba.Se empleó un total de 170 ratas que fueron tratadas con la vacuna, su placebo (todos los componentes, excepto la materia prima activa), o que no recibieron tratamiento alguno (controles). Se realizaron observaciones clínicas diarias durante todo el ensayo, se determinó el consumo de agua y alimentos y se realizaron investigaciones anatomopatológicas a animales sacrificados 3, 7, 14, 21, 28, 35 y 42 días después de la inoculación. No se observaron muertes ni síntomas de toxicidad; no se encontraron diferencias estadísticamente significativas entre los pesos vivos, el consumo de agua ni el de alimentos entre los grupos del ensayo. Tampoco se observaron lesiones anatomopatológicas que indicaran toxicidad por parte del producto inoculado. Los resultados permitieron concluir que la potencialidad de la vacuna vax-TyVi para producir efectos adversos locales es baja.

Novel Two-Component Systems Implied in Antibiotic Production in Streptomyces coelicolor
Ana Yepes,Sergio Rico,Antonio Rodríguez-García,Ramón I. Santamaría,Margarita Díaz
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0019980
Abstract: The abundance of two-component systems (TCSs) in Streptomyces coelicolor A3(2) genome indicates their importance in the physiology of this soil bacteria. Currently, several TCSs have been related to antibiotic regulation, and the purpose in this study was the characterization of five TCSs, selected by sequence homology with the well-known absA1A2 system, that could also be associated with this important process. Null mutants of the five TCSs were obtained and two mutants (ΔSCO1744/1745 and ΔSCO4596/4597/4598) showed significant differences in both antibiotic production and morphological differentiation, and have been renamed as abr (antibiotic regulator). No detectable changes in antibiotic production were found in the mutants in the systems that include the ORFs SCO3638/3639, SCO3640/3641 and SCO2165/2166 in any of the culture conditions assayed. The system SCO1744/1745 (AbrA1/A2) was involved in negative regulation of antibiotic production, and acted also as a negative regulator of the morphological differentiation. By contrast, the system SCO4596/4597/4598 (AbrC1/C2/C3), composed of two histidine kinases and one response regulator, had positive effects on both morphological development and antibiotic production. Microarray analyses of the ΔabrC1/C2/C3 and wild-type transcriptomes revealed downregulation of actII-ORF4 and cdaR genes, the actinorhodin and calcium-dependent antibiotic pathway-specific regulators respectively. These results demonstrated the involvement of these new two-component systems in antibiotic production and morphological differentiation by different approaches. One is a pleiotropic negative regulator: abrA1/A2. The other one is a positive regulator composed of three elements, two histidine kinases and one response regulator: abrC1/C2/C3.

Abstract: In cement-based materials porosity plays an important role in determining their mechanical and transport properties. This paper describes an improved low–cost embeddable miniature NMR sensor capable of non-destructively measuring evaporable water loss and porosity refinement in low and high water-to-cement ratio cement-based materials. The sensor consists of two NdFeB magnets having their North and South poles facing each other, separated by 7 mm to allow space for a Faraday cage containing a Teflon tube and an ellipsoidal RF coil. To account for magnetic field changes due to temperature variations, and/or the presence of steel rebars, or frequency variation due to sample impedance, an external tuning circuit was employed. The sensor performance was evaluated by analyzing the transverse magnetization decay obtained with a CPMG measurement from different materials, such as a polymer phantom, fresh white and grey cement pastes with different w/c ratios and concrete with low (0.30) and high (0.6) w/c ratios. The results indicated that the sensor is capable of detecting changes in water content in fresh cement pastes and porosity refinement caused by cement hydration in hardened materials, even if they are prepared with a low w/c ratio (w/c = 0.30). The short lifetime component of the transverse relaxation rate is directly proportional to the compressive strength of concrete determined by destructive testing. The r 2 (0.97) from the linear relationship observed is similar to that obtained using T 2 data from a commercial Oxford Instruments 12.9 MHz spectrometer.

Abstract: among bullous diseases, pemphigus vulgaris (pv) is a classical variety of this type of skin disorders. to establish the real prevalence of thyroid abnormalities in such a disease, a prospective study was developed. for this reason, thyroid evaluation was performed in 15 consecutive patients who attended the dermatology clinic for pv and in a group of 15 healthy volunteers (control group) matched by age and gender. thyroid function was evaluated by measuring t3, t4 and tsh. the presence or absence of goiter was searched by palpation, while thyroid autoimmunity was investigated through the assay of thyroperoxidase antibodies (tpo-ab). in each group there were 9 women and 6 men, aging 25-65 years (mean = 48.3 y) in the pv group, and 25-69 years (mean = 45.4 y) in the control group. it was found that 7 patients (46.6%) of the pv group and 1 subject (6.7%) of the control group (p < 0.015) disclosed thyroidal alterations. positive titers of tpo-ab were observed in 6 patients with pv and in one volunteer. goiter and subclinical hypothyroidism were found in one pv patient with negative tpo-ab. out of the total 7 cases with positive tpo-ab, only a pv patient had an overt hashimoto?s thyroiditis. all other cases had only the presence of thyroid auto-antibodies without clinical evidences of chronic thyroiditis. it is concluded that pv is highly associated with primary thyroid disorders, mainly with positive titers of tpo-ab, although most patients do not present overt clinical thyroid disease.

Abstract: La brucelosis es una zoonosis que se trasmite directa o indirectamente al hombre, a partir de reservorios animales, y es considerada una enfermedad ocupacional. Con el objetivo de estratificar el riesgo de brucela, para el dise o de un sistema de vigilancia, se realizó una investigación de innovación tecnológica bietápica durante los a os 2009-2010 en el municipio San Cristóbal. Durante la primera se estratificó el riesgo de brucela y en la segunda, se dise ó un sistema de vigilancia. Las unidades de análisis para la investigación están constituidas por la totalidad de animales, pertenecientes al sector estatal del municipio, de la cual se abastece (carnes, leche y derivados), la población y la totalidad de trabajadores expuestos ocupacionalmente al riesgo de brucela. La brucelosis es un importante problema de salud entre la masa animal, incide en ello, los bovinos, porcinos y los búfalos, todas las fuentes de alimento de la población, las principales zonas de riesgo para la salud de los humanos se encuentran en los Consejos Populares José Martí y López Pe a, considerados estos de alto riesgo epidemiológico para la salud de la población. Se propone un sistema de vigilancia conjunto con medicina veterinaria que garantizará el control de la enfermedad, tanto en los animales como en las personas.
