SVM en paralelo para optimizar el tiempo de respuesta en la predicción de co-receptores de los virus R5, X4 Y R5X4 (mutado) que causan el Sida (VIH-1) en células CD4

In particular, the R5 HIV-1 viruses use CCR5 as co-receptor for the virus entrance, the X4 virus HIV-1 use the CXCR4, while some strange viruses known as R5X4 or D-tropic, have the ability to use both co-receptors. The X4 and R5X4 viruses are associated with rapid progress in HIV-1. In this article a series of experiments will be carried out to implement a Supervised Learning Machine in Parallel that allows optimizing the response time in the prediction of co-receptors (CCR5, CXCR4) of the virus that cause AIDS (HIV-1) in CD4 cells. To implement the machine in parallel we will use Snow in R. Snow provides the support to easily execute functions in R in parallel. Most functions in parallel in Snow are variations of the standard lapply () function. To implement the functions in parallel, Snow uses a master / slave architecture where the teacher sends tasks to the workers, and the workers execute the tasks and return the results to the teacheR.

Peróxido de Hidrógeno al 35% y su efecto sobre la microdureza dental

Peroxides are currently the most widely used products for tooth whitening, when peroxide decomposes it produces a decrease in the pH in the medium in which it is found, immediately in the enamel produces acid etching that varies depending on the pH of the product, contact time and concentration. Objectives: To know the effect of hydrogen peroxide at 35% on dental microhardness. Methodology: Experimental, transversal, descriptive study. Using 50 teeth that were cut 1 mm below the amelocemental junction to create two vestibular and palatal faces. The teeth were lightened with 35% hydrogen peroxide to find out how much micro-hardness the enamel loses, the Vickers unit of measurement. The microhardness was measured after making 3 indentations in different surfaces of the enamel at a force of 50 grams and a time of 20 seconds with a diamond tip that left a trace observed under the microscope in the form of a pyramidal diamond; based on the vertical and horizontal diagonals, the Vickers microhardness was determined. Contribution: According to the results obtained, we found that the application of 35% hydrogen peroxide decreased dental microhardness by 25.08%.

Diagnóstico higiénico-sanitario e identificación de factores de riesgo en restaurantes

The purpose was to make a hygienic-sanitary diagnosis and risk factors identification in 81 fixed establishments of food restoration located in the metropolitan area of Guadalajara, Jalisco, Mexico. The establishments were grouped according to the North American Industry Classification System (NAICS). The sanitary verification act, based on NOM-251-SSA1-2009, was applied. The minimum was 85 % in order to consider the evaluation was approved. 26 places approved the evaluation, the three best qualified, belong to franchises, 55 establishments were failed. Statistically it represents the same as the service corresponds to any of the NAICS categories addressed in the study. The risk factors detected in order of importance are associated with the following programs: quality control in water for general use; staff training; transport; pest control; operations control; maintenance and cleaning; Facilities and areas; quality control of the water in contact with foods. The written and operational absence of prerequisite programs was evidenced, so the conditions and measures applied are not sufficient to ensure the quality and safety of the food, and therefore represent a potential disease risk for diners in local restaurants.

Índice de masa corporal, conductas alimentarias de riesgo y percepción de la imagen corporal en estudiantes de un colegio de bachilleres en Yucatán, México

Adolescence is related to physical and psychological changes and is an important factor for the development of body image. At this stage, body awareness increases due to physical changes, society's importance to physical traits and the growing tendency to compare with cultural norms; in adolescents of both sexes there is the possibility of rapid increases in height and weight, but in women, these body changes are associated with a higher prevalence of overweight and obesity; At present, people's lifestyle has changed since bad eating habits, sedentary lifestyle and stress have dominated and physical activity has decreased. The objective of this work was to establish the relationship between the real BMI, risky eating behaviors and the perception of body image in students of a high school in the state of Yucatan. The study was cross-sectional; 212 students participated. Two thirds of the participants were perceived with a body that does not correspond to theirs. A relationship was found between real BMI and perceived BMI, as well as between BMI and the presence of risky eating behaviors.

Diseño y manufactura de ortesis dinámica para mano mediante el modelado por deposición fundida (MDF)

Currently a large number of hand injuries occur in the Mexican population, mainly caused by accidents at work and in sports activities. To help the population have access to a brachiopalmar rehabilitation, In this work it was proposed to develop a rehabilitative prototype “dynamic hand orthosis” to address the main pathologies that affect our society (fractures, dislocations, sprains, tendonitis and sx of the carpal tunnel). The design was analyzed in a finite element for its validation, having a safety factor of 2.6 and a maximum tension of 12.84 MPa below the ABS elastic limit, Manufacturing was done using a 3D printer with the ABS filament. This orthosis has an extensor finger attachment composed of hammocks, one for each finger. Due to its universal design, it can be used for both hands only by exchanging the extension of the thumb.
