La obesidad desde la perspectiva de la selección de alimentos.

La obesidad es un problema de salud a nivel mundial, así como en México. La iniciación de la alimentación se ha estudiado desde la perspectiva de la homeostasis. El aprendizaje es un mecanismo de adaptación que permite la regulación de la alimentación en ausencia de señales de error, como lo implican las estrategias basadas en perturbaciones de las variables reguladas homeostáticamente y provee un mecanismo flexible y dinámico especialmente en ambientes predecibles. En el aprendizaje de preferencias alimenticias, el sabor del alimento se asocia con sus efectos. La selección de alimentos tiene una base en la influencia social y puede proveer estrategias para controlar la obesidad mediante la limitación en la cantidad de carbohidratos consumidos. Se ha encontrado que las dietas bajas en carbohidratos producen una disminución de peso mayor que la limitación del contenido de grasa en la dieta. En las dietas bajas en carbohidratos, una variedad de éstas que se ha encontrado efectiva en reducción de peso es la dieta cetogénica. La selección de alimentos mediada socialmente puede ayudar a resolver el problema de la obesidad causada por el consumo excesivo de carbohidratos mediante la influencia activa para seleccionar alimentos de una lista

A rapid method for interfacial tension calculation between rock plug and crude oil based on contact angles, application for EOR

"Interfacial tension and contact angle are two specific important parameters to take decisions for enhanced oil recovery, for instance, proper chemicals to use for surface tension reduction, expected wettability of solids, interaction between crude oil and rock. For this purpose, the article presents a method for easy calculation of the solid-liquid interfacial tension based on contact angle measurements applying Neumann's correlation and Young's equation. The main idea stands on the calculation of the rock parameters, like wettability, with known substances and extend these results to crude oils. It was possible, based on the results obtained, to establish a relationship between solid-liquid interfacial tension and contact angle for the crude oil – rock system, which can definitively be used for the calculation of interfacial tension of any other fluid spread out on the same kind of rock. A linear regression was obtained with an accuracy as good as R2 = 0.9989. Viscosity as a function of contact angle could also be obtained for the studied crude oils in the same kind of rock.

Online detection and SNR estimation in cooperative spectrum sensing

ABSTRACT: Cooperative spectrum sensing has proved to be an effective method to improve the detection performance in cognitive radio systems. This work focuses on centralized cooperative schemes based on the soft fusion of the energy measurements at the cognitive radios (CRs). In these systems, the likelihood ratio test (LRT) is the optimal detection rule, but the sufficient statistic depends on the local signal-to-noise ratio (SNR) at the CRs, which are unknown in most practical cases. Therefore, the detection problem becomes a composite hypothesis test. The generalized LRT is the most popular approach in those cases. Unfortunately, in mobile environments, its performance is well below the LRT because the local energies are measured under varying SNRs. In this work, we present a new algorithm that jointly estimates the instantaneous SNRs and detects the presence of primary signals. Due to its adaptive nature, the algorithm is well suited for mobile scenarios where the local SNRs are time-varying. Simulation results show that its detection performance is close to the LRT in realistic conditions.This work was supported in part by the Ministerio de Ciencia, Innovación y Universidades, jointly with European Commission [European Regional Development Fund (ERDF)], under Grant TEC2017-86921-C2-1-R and Grant TEC2017-86921-C2-2-R (CAIMAN) and in part by The Comunidad de Madrid under Grant Y2018/TCS-4705 (PRACTICO-CM)

Identification of Cryptotermes brevis (Walker, 1853) and Kalotermes flavicollis (Fabricius, 1793) Termite Species by Detritus Analysis

Producción CientíficaWe carried out morphological and dimensional analysis of the detritic elements deposited in the galleries of two termite species of the Kalotermitidae family present in Spain known as drywood termites (Cryptotermes brevis (Walker, 1853) and Kalotermes flavicollis (Fabricius, 1793)). This was in order to gauge the possibility of differentiating the species only on the basis of debris observation and analysis. Ten samples from six different geographical sources were analyzed and measured. Significant statistical differences were found between these two termite species in all measured parameters, and multivariate statistical models, able to predict species on the basis of dimensional measurements, were developed, with a degree of success higher than 75%. The most important dimensional differences were length and width, as well as the variable hexagonal shape of the cross-section of the detritic elements. The detritic elements of both species had a variable form of a hexagonal prism with slightly concave faces, and with pointed or rounded ends. Those of the Cryptotermes brevis species were significantly larger, less elongated, and had a smaller concavity on the faces of the prism. Color was found to be particularly variable in both species, and was not useful. Nevertheless, the debris of Kalotermes flavicollis was markedly “dirty” (mixed with other wood remains)

Metabolic Syndrome, depression and patient safety culture in Mexican resident physicians

Background: Medical residence can affect the well-being and health of resident physicians (rp), which are directly related to the quality of medical care and patient safety. El objective was to identify the prevalence of metabolic syndrome (MetS), depressive symptoms, and evaluate the culture of patient safety in resident physicians. Methods: Cross-sectional analytical survey of 106 physicians residing in 13 medical specialties of a public hospital in Mexico. MetS was defined according to who criteria and depressive symptoms using the cesd-r scale; the culture of patient safety was evaluated with the Spanish version of the Hospital Survey on Patient safety. Results: 53.7% had a combined prevalence of overweight/obesity and insulin resistance was found in 33%. 8.5% of rp had prediabetes and 2.5% diabetes. 23.6% of the sample presented two MetS components. The prevalence of MetS was 8.5% and depressive symptoms were found in 21.7% of rp. The evaluation of the culture of patient safety showed strength in the dimensions of teamwork in the unit-service, organizational learning- continuous improvement, expectations and actions of the direction and frequency of reported events, perception of patient safety culture was found in 8/10 rp. Conclusions: A high prevalence of cardiometabolic alterations and depressive symptoms was found in Mexican rp. It is necessary to promote self-care for health and to strengthen the concept of patient safety culture among resident physicians

The Role of Lipopeptidophosphoglycan in the Immune Response to Entamoeba histolytica

The sensing of Pathogen Associated Molecular Patterns (PAMPs) by innate immune receptors, such as Toll-like receptors (TLRs), is the first step in the inflammatory response to pathogens. Entamoeba histolytica, the etiological agent of amebiasis, has a surface molecule with the characteristics of a PAMP. This molecule, which was termed lipopeptidophosphoglycan (LPPG), is recognized through TLR2 and TLR4 and leads to the release of cytokines from human monocytes, macrophages, and dendritic cells; LPPG-activated dendritic cells have increased expression of costimulatory molecules. LPPG activates NKT cells in a CD1d-dependent manner, and this interaction limits amebic liver abscess development. LPPG also induces antibody production, and anti-LPPG antibodies prevent disease development in animal models of amebiasis. Because LPPG is recognized by both the innate and the adaptive immune system (it is a “Pamptigen”), it may be a good candidate to develop a vaccine against E. histolytica infection and an effective adjuvant
