Paleomagnetismo e isotopos de Hf en rocas del Cretacico Inferior del Terreno Guerrero, Bahia Chamela e Isla Cocinas (Jalisco, Mexico): implicaciones tectonicas
Authors: Montaño-Cortes Paola Catalina , Molina-Garza Roberto Stanley , Iriondo Alexander 
Published: December 2019

La extensión sur de la Cordillera Occidental de Norte América, en el occidente de México, está integrada por terrenos acrecionados que conforman el superterreno Guerrero. Estos elementos tectónicos están compuestos por rocas volcánicas y volcano-sedimentarias del Jurásico Superior al Cretácico, que descansan sobre un basamento meta-sedimentario de supuesta edad triásica, esquistos con tobas y basaltos con química de MORB. En el subterreno Zihuatanejo se reconoce a la Formación Tecalitlán del Cretácico Inferior aflorando en Bahía Chamela e Isla Cocinas (Jalisco), donde en su parte norte estas rocas son aparentemente intrusionadas por el batolito de Puerto Vallarta. Esta unidad está compuesta principalmente por flujos volcánicos andesíticos, depósitos epiclásticos desde tobas a brechas y algunas areniscas. De esta secuencia se obtuvieron 35 sitios para paleomagnetismo, dos muestras para geocronología U-Pb y una de estas para análisis de Hf en zircones con el objetivo de establecer su relación paleogeográfica con el resto de México, así como establecer una edad absoluta y la naturaleza de la corteza del bloque Jalisco del subterreno Zihuatanejo. Los resultados obtenidos muestran que las rocas volcánicas de la Fm. Tecalitlán son andesitas y dacitas con una edad U-Pb en zircones de 120 ± 1 Ma. Los isótopos de Hf en zircones presentan eHf inicial entre +7.2 y +11.5 y edades modelo Hf TDM2C (“two-stage Hf model ages”) entre 442 y 714 Ma (media 557 Ma), indicando que no existe una contaminación significativa de corteza continental evolucionada similar a la que existe en el este de México (Oaxaquia). La magnetización remanente de estas unidades es multivectorial. Se identificaron tres componentes paleomagnéticas, donde la componente C es la característica de polaridad dual, con media de D = 341.0° e I = 38.9° (n = 25 sitios, k = 15.1, a95 = 7.7°), indicando paleolatitudes norte de 21.8°+/-3.8°. Comparando la paleolatitud obtenida en este trabajo con las paleolatitudes esperadas para el Aptiano calculadas a partir del polo de referencia de compilaciones globales recientes (28° a 26.2°), se concluye que la parte occidental del superterreno Guerrero estaba cercana a su latitud actual con respecto al cratón Norteamericano a los 120 Ma. Los isótopos de Hf son consistentes con modelos que interpretan al subterreno Zihuatanejo como un arco intra-oceánico, y no con los modelos que sugieren la separación de un fragmento de Oaxaquia por la apertura de una cuenca de tras-arco.

Published: December 2019

Garlic as feed additives have been widely used to increase animals performance due to it can help absorption process of nutrients so that it can spur animal growth and produce healthy products. Garlic is crushed or damaged easily and when is broken, some of these bioactive sulfur components produce a strong pungent odor. Black garlic is fresh garlic that has been fermented for a period of time. Black garlic is formed through heating and causing the garlic turn to black because of its browning compounds. Black garlic does not exude a strong off-flavor, like fresh garlic because of changes to the compound allicin, which is responsible for its odor. The study was done to measure the nutritional content on black garlic based on different times of heat treatment at 600C. The research design was complete randomized design (CRD) with 4 treatments and 5 replications. The treatments were time of heating; P0 (control, 0 day), P1 (15 days), P2 (30 days) and P3 (45 days) 500 g each. Parameters were moisture content, crude protein, ash, fat and carbohydrate. Data were analysed by analysis of variance, the significant effects were tested by Duncan’s multiple range test. To determine the best time of heating would be tested by Polynomial orthogonal. The results showed that different times of heat treatment significantly (P<0.05) affect nutrition of black garlic. Fifteen days of heating significantly incease moisture content but the moisture content decreased when heating was longer such as for 30 and 45 days. Longer time of heating increased significantly (P <0.05) the protein and fat content of black garlic, while the carbohydrate content significantly decreased (P <0.05). Polynomial orthogonal test resulted that the heating of garlic at 600C for 17 days gives the best nutrient content of black garlic. It was concluded that the length heating of garlic to produce the best nutrition content of black garlic was at a temperature of 600C for 17 days.

In recent years, there has been an increase in the incidence of salmonellosis in children, including in the Yaroslavl region by 52.7%.In order to study salmonellosis in children at the present stage, we observed 185 patients aged from 1 month to 18 years who were hospitalized in the Infectious Clinical Hospital of the city of Yaroslavl from 2015 to 2017. The analysis of the main clinical, epidemiological and laboratory parameters was carried out and the peculiarities of the course of salmonellosis in children were established.Results: Salmonella enteritidis remains the dominant pathogen. The children of the first 3 years of life prevailed — 65.4%, of which under the age of 1 year — 18.9%, unorganized in preschool institutions — 49.2%. Alimentary infection was found in 49.7% of cases. In 71.4% of patients, the disease developed against a background of concomitant pathology. In most cases (74.1%), damage to the gastrointestinal tract was manifested by gastroenterocolitis or enterocolitis. In 38.9% of cases, salmonellosis occurred in combination with bacterial and viral pathogens, especially with rota and noroviruses (81.9%), which aggravated the course of the infection. Severe forms accounted for 24.9% and were due to the development of dehydration, mainly in patients with mixed infections.

The study is devoted to the clinical examination of frequently ill children in the North-Eastern regions of Russia and the laboratory detection of markers of herpesvirus infections, as well as pneumocystosis and the establishment of the relationship with their immune status.62 children aged 8—15 years were examined. Samples of serum and blood cells, sputum on markers of herpesvirus infections and pneumocystosis by ELISA, indirect immunofluorescence reaction and rapid culture method were studied. Assessment of humoral immunity and determination of circulating immune complexes was performed by solid-phase enzyme immunoassay and immune turbodimetric analysis.The study shows the etiological role of herpesviruses. Active infection (acute, reactivation) was caused in 9.7% of cases of HSV-1,2, 12.9% — EBV, 6.5% — CMV, 19.4% — HHV-6. This is indicated by a large number of convalescents: with EBVI — 40.3%, HSVI — 27.4%, HHVI-6 — 8.1%, CMVI — 4.8%. Also, a significant number of children were found and latent form. The formation of the circulating immune complexes (CIC) is a physiological mechanism of protection of the body, and their excessive accumulation indicates the development of inflammatory processes and autoimmune diseases. In the increase in CIC observed mainly in individuals with latent infection: HSVI — 29.4%; HHVI-6 — 20.8%; CMVI — 16.7%, EBVI — 11.9%. It is important to note that in almost half of the cases the increase in CIC level occurred simultaneously with the increase in the concentration of total IgE. A survey of children on Pneumocystis showed that among them, dominated native — 11.3%, in which the sputum was identified pnevmotsisty. It should be noted that one child was found mixed infection with reactivated CMVI. Acute infection was diagnosed only in 6.4% of the patients.

Authors: BULLO Tesfaye , DURESSA Gemechis , DEGLA Guy 
Published: December 2019

In this paper, we consider singularly perturbed parabolic convection-diffusion initial boundary value problems with two small positive parameters to construct higher order fitted operator finite difference method. At the beginning, we discretize the solution domain in time direction to approximate the derivative with respect to time and considering average levels for other terms that yields two point boundary value problems which covers two time level. Then, full discretization of the solution domain followed by the derivatives in two point boundary value problem are replaced by central finite difference approximation, introducing and determining the value of fitting parameter ended at system of equations that can be solved by tri-diagonal solver. To improve accuracy of the solution with corresponding higher orders of convergence, we applying Richardson extrapolation method that accelerates second order to fourth order convergent. Stability and consistency of the proposed method have been established very well to assure the convergence of the method. Finally, validate by considering test examples and then produce numerical results to care the theoretical results and to establish its effectiveness. Generally, the formulated method is stable, consistent and gives more accurate numerical solution than some methods existing in the literature for solving singularly perturbed parabolic convection- diffusion initial boundary value problems with two small positive parameters.

Published: December 2019

El trabajo pone el eje en el respeto de la garantía de cobertura de cargos en dos premisas derivadas del artículo 16 de la Constitución Nacional: exigir idoneidad en los postulantes y habilitar a todos los habi­tantes de la Nación a demostrar tal requisito. Dicho postulado es conside­rado un principio estructural previsto en el programa constitucional inicial como ínsito en el sistema republicano de gobierno constituyendo, tanto un derecho exigible por cada habitante del Estado como un deber para las autoridades de cada una de las esferas de gobierno que conforman nuestro sistema federal. Considera la previsión de cupos necesarios para resguardar a determinadas categorías desaventajadas -en muchos casos por prejuicios culturales que deben superarse- dentro de los cuales debe respetarse el principio de selección previsto constitucionalmente. Des­cribe distintos fallos en los que se aborda la aplicación del requisito de idoneidad como exigencia en la cobertura de cargos públicos.

Aims
The use of MitraClip (Abbott Vascular, Santa Clara, California, USA) for the treatment of severe functional mitral valve regurgitation (FMR) has drastically increased over recent years. We analysed the Worldwide and European interest on the MitraClip among Internet users performing a Google Trends-based analysis.

Methods
We conducted a retrospective analysis extracting the data from the cited Google Trends (https://trends.google.com) to explore both the worldwide and European interest in the MitraClip over recent years. Specifically, Google Trends was queried from 1 January 2008 to 31 September 2019 using the item ‘MitraClip’.

Results
Over the study period, the worldwide interest in the MitraClip steadily increased by 47.7% per month (P
trend < 0.001). The analysis performed among the 11 European countries in which the search volume allowed a trend to be created over the study period confirming an increasing significant interest. Specifically, the higher rate of interest increase per month was registered in France followed by Poland, Spain and Italy (40.5, 35.9, 37.3 and 31.8%, respectively).

Conclusion
A growing interest in the MitraClip exists both in Europe and worldwide.

Background
The association between atrial fibrillation and dementia has been described. Whether a specific association exists between atrial fibrillation and Alzheimer's disease remains uncertain. This study aims to assess the association between atrial fibrillation and Alzheimer's disease through a systematic review and meta-analysis of the literature.

Methods
An exhaustive search of electronic databases up to October 2018 was conducted. Studies that identified patients with and without atrial fibrillation as well as patients with and without Alzheimer's disease and reported results of at least one relevant outcome, including hazard ratio of the association between atrial fibrillation and Alzheimer's disease were included in this analysis. The hazard ratios and their confidence interval were then pooled using a DerSimonian and Laird random effects model.

Results
Six studies enrolling a total of 56 370 patients were included. At baseline, the mean or median ages ranged from 50 to 78 years with a subsequent follow-up of 3 to 25 years. The random-effect pooled analysis showed a hazard ratio of 1.30 (95% confidence interval 1.01–1.59) and the heterogeneity was not significant, I
2 48.1%. All of the included studies were rated as good quality.

Conclusion
Pooled analysis suggest that patients with atrial fibrillation may be exposed to an increased risk of developing new onset of Alzheimer's disease. Given the relevant clinical implications, further studies are required to corroborate these findings.
