Infrared glucose portable device

There are quite a few persons worldwide with severe issues to control the glucose level on its blood. Only in Mexico, there are about 10 million persons with this disease and well over 13 deaths in 100 in this country are due to diabetes. In order to help to control this health issue, we are proposing a device to measure in a swift, simple and efficient way abnormality glucose levels in blood by using infrared sensors. Glucose shows a high absorbance to infrared wavelength. By using such characteristic, it is possible to develop a mobile, low-cost electronic device capable to analyse a blood sample by measuring the absorbance in it. The process is performed by using an array of infrared diodes controlled by a low-power consumption microcontroller as well as by several algorithms within a case. A blood sample is put in a substrate within the case. Once analysed, the glucose level of such sample is analysed and displayed on a scree

Mesenchymal Stem Cells for Clinical Use after Spinal Cord Injury

Since multipotential and immunoregulatory properties were identified in mesenchymal stem cells (MSCs) in the twentieth century, they have been proposed as an effective therapy for many degenerative and traumatic diseases such as spinal cord injury (SCI). SCI is a devastating event with a high mortality rate that evokes the loss of motor and sensory functions due to neurochemical imbalance and an exacerbated immune response as a consequence of the initial mechanical damage, which in conjunction creates a hostile microenvironment that inhibits neuronal circuitry restoration. This chapter pretends to lead the reader towards the immunomodulatory, differentiation, and tissue repairing capacities of MSCs that allow them to be a valuable candidate for clinical trials. In the first section, the physiopathology of SCI will be addressed; after that, the chapter will review the general aspects of MSCs such as origin, molecular markers, and the different mechanisms by which MSCs can heal the target tissues. Finally, we will discuss clinical trials involving autologous MSC transplantation and their limitations

Obtención de quitosano a partir de exoesqueleto de langostino blanco (litopenaeus vannamei), para el tratamiento de efluentes industriales

En la presente investigación se obtuvo la quitina y el quitosano a partir del exoesqueleto de langostino Blanco (Litopenaeus vannamei), variando algunos parámetros respecto a los protocolos reportados en otros trabajos de investigación. El procedimiento propuesto para la extracción desde el exoesqueleto involucró procesos de desmineralización, desproteinización y desacetilación. El quitosano ha demostrado ser un buen coagulante durante el tratamiento de aguas residual. En el proceso de extracción de quitosano el rendimiento es mayor a temperatura de 75ºC y una relación Quitina/NaOH de 1:5. El biopolímero obtenido se empleó para realizar la evaluación de coagulación de muestras de aguas contaminadas observando el rendimiento de remoción de color, obteniendo el máximo rendimiento a un pH de 7 y una concentración de quitosano de 60 ml de solución a una concentración de 1mg/100ml de solución.Tesi

Nueva Normalidad en las Micro Unidades Económicas Turísticas de la Sierra Norte de Puebla

La actividad turística, una de las más dañadas en la Sierra Norte del Estado de Puebla (México) por la crisis del coronavirus COVID-19 provocó el cierre parcial o total de decenas de Micro Unidades Económicas (MUE), poblaciones como Cuetzalan del Progreso y Chignahuapan donde se realizó el presente estudio, reconocen que deberán adaptarse a las nuevas circunstancias, tanto en espacio, capacitación y difusión para mantener su presencia en los consumidores a través de sus servicios; de ahí que los giros empresariales como Hoteles, Tours, Restaurantes entre otros, deberán mantener una comunicación continua, información oportuna y adaptarse rápidamente a las normas que se dicten oficialmente en la materia con el fin de reinsertarlos a la dinámica económica de la región. Se realizó un análisis metodológico mixto de UE con giros turísticos, de donde se identificaron factores organizacionales externos, internos y de comunicación, cuyos resultados reflejaron numerosas áreas de oportunidad para una toma la de decisiones para diseñar y proponer estrategias de mercadotecnia, adaptadas a las tendencias internacionales que se toman debido a la afectación del SARS CoV2.   The COVID-19 crisis affected a lot of activities in the Sierra Norte of the State of Puebla (Mexico) including tourism activity. This resulted to the partial or total closure of dozens of Micro Economic Units (EUTM). This study was carried out in Cuetzalan del Progreso and Chignahuapan and they realised the need to adapt to the new circumstances both in space, training, and dissemination to maintain their consumers through their services. For this reason, business tours such as hotels and restaurants must maintain a continuous communication, timely information, and adapt quickly to the rules that are officially dictated in this field in order to reinsert them to the economic dynamics of the region. A mixed EU methodological analysis was carried out from which external, internal, and communication organizational factors were identified. This resulted to numerous areas of opportunity for decision-making to design and propose marketing strategies, which are adapted to international trends that are taken due to the involvement of SARS CoV2

Rampant Arch and Its Optimum Geometrical Generation

Gothic art was developed in western Europe from the second half of the 12th century to the end of the 15th century. The most characteristic Gothic building is the cathedral. Gothic architecture uses well-carved stone ashlars, and its essential elements include the arch. The thrust is transferred by means of external arches (flying buttresses) to external buttresses that end in pinnacles, which accentuates the verticality. The evolution of the flying buttresses should not only be considered as an aesthetic consideration, but also from a constructive point of view as an element of transmission of forces or loads. Thus, one evolves from a beam-type buttress to a simple arch, and finally to a rampant arch. In this work, we study the geometry of the rampant arch to determine which is the optimum from the constructive point of view. The optimum rampant arch obtained is the one with the common tangent to the two arches parallel to the slope line. A computer program was created to determine this optimal rampant arch by means of a numerical or graphical input. It was applied to several well-known and representative cases of Gothic art in France (church of Saint Urbain de Troyes) and Spain (Cathedral of Palma de Mallorca), establishing if they were designs of optimal rampant arches or not

Organic carbon, water repellency and soil stability to slaking under different crops and managements: a case study at aggregate and intra-aggregate scales

This research studies the distribution of organic C and intensity of water repellency in soil aggregates with different size and in the interior of aggregates from Mediterranean soils under different crops (apricot, citrus and wheat) and management (con- 5 ventional tilling and no tilling/mulching). For this, undisturbed aggregates were sampled and carefully divided in size fractions (0.25–0.5, 0.5–1, 1–2, 2–5, 5–10 and 10–15 mm) or peeled to obtain separated aggregate layers (exterior, transitional and interior). Organic C content in the fine earth fraction of soils under different crops did not show important variations, although it increased significantly from conventionally tilled to 10 mulched soils. The distribution of organic C content in aggregates with different size varied among soils under different crops, generally increasing with decreasing size. At the intra-aggregate level, organic C concentrated preferably in the exterior layer of aggregates from conventionally tilled soils, probably because of recent organic inputs or leachates. In the case of mulched soils, higher concentrations were observed, but 15 no significant differences among aggregate regions were found. The intensity of water repellency, determined by the ethanol method, did not show great variations among crops, but increased significantly from conventionally tilled to mulched soils. Coarser aggregates were generally wettable, while finer aggregates showed slight water repellency. Regardless of variations in the distribution of organic C in aggregate layers from 20 conventionally tilled soils, great or significant differences in the distribution of water repellency at the intra-aggregate level were not found in any case. Finally, the intensity of water repellency was much more important than the concentration of organic C in the stability to slaking of aggregates.Ministerio de Ciencia e Innovación CGL2010-21670-C02-01Ministerio de Ciencia e Innovación CGL2012-38655-C04-0

Anti-inflammatory activity of

The anti-inflammatory activity of the chloroform, methanol and aqueous extracts of Wigandia urens and Acalypha alopecuroides were investigated on carrageenan-induced paw edema at doses of 400 mg/kg. The three extracts of W. urens, and the aqueous extract of A. alopecuroides caused significantinhibition of the edema (58.1±6.5% and 63.5±5.4%, respectively). Indomethacin was used as positive control (8 mg/kg), and inhibited edema by 66.3±5.2%. The methanol extract of W. urens and the aqueous extract of A. alopecuroides, at doses of 200 mg/kg, inhibited pellet implantation-induced granuloma formation by 69.4±6.5 and 70.6±6.6%, respectively. These levels of inhibition are higher than those exhibited by naproxen at doses of 50 mg/kg (46.1±7.1%). Both extracts showed activity on adjuvantinduced arthritis in rats, with the best effect being observed after 96 h (82.2±4.6 and 80.6±7.3%, respectively)
